    Intracranial metastatic lesions arise through a number of routes. Therefore, they can involve any part of the central nervous system and their imaging appearances vary. Magnetic resonance imaging (MRI) plays a key role in lesion detection, lesion delineation, and differentiation of metastases from other intracranial disease processes. This article is a reasoned pictorial review illustrating the many faces of intracranial metastatic lesions based on the location - intra-axial metastases, calvarial metastases, dural metastases, leptomeningeal metastases, secondary invasion of the meninges by metastatic disease involving the calvarium and skull base, direct or perineural intracranial extension of head and neck neoplasm, and other unusual manifestations of intracranial metastases. We also review the role of advanced MRI to distinguish metastases from high-grade gliomas, tumor-mimicking lesions such as brain abscesses, and delayed post-radiation changes in radiosurgically treated patients.

    In a study of intracranial metastases, 46 cases having satisfactory clinical, operative and histological proofs were analyzed by computerized tomography at Presbyterian Medical Center from May, 1982 to February, 1986. The results were as follows: 1. The male to female ratio of intracranial metastases were 67:33. The 5th decade group (34.8%) was the most prevalent age group, followed by the 6th decade (21.7%) and 7th decade (21.7%). 2. The number of lesions was found be: single -25 cases (54.3%); multiple -21 cases (45.7%). 3. The source of intracranial metastases found to be: lung 15 cases (32.6%); unknown 12 cases (26.0%); chorioca 3 cases (6.5%); liver 3 cases (6.5%); stomach 2 cases (4.3%); parotid, breast, kidney, prostate, melanoma, rectal ca, rhabdomyosarcoma, nasal ca, lymphoma, testicular ca, cervix, each 1 case (2.2%). 4.

    Verma, Nipun; Nolan, Craig; Hirano, Miki; Young, Robert J


    We present an unusual case of a patient with an intracranial low-grade oligodendroglioma who developed recurrence with an intramedullary spinal cord metastasis and multiple spinal leptomeningeal metastases. The intramedullary spinal cord metastasis showed mild enhancement similar to the original intracranial primary, while the multiple spinal leptomeningeal metastases revealed no enhancement. This is the seventh reported case of symptomatic intramedullary spinal cord metastasis from a low-grade oligodendroglioma.

    Full Text Available Background: The most common sites of origin for neuroendocrine carcinoma are gastrointestinal tract and its accessory glands, and lungs. Materials and Methods: One-hundred fifty cases diagnosed with metastatic brain lesions were retrieved from hospital records within 5 years. For these cases, the primary neoplasm, histopathological classification, metastasis, treatment, and fate all were studied. Results: Intracranial deposits were detected in 10%. The primary lesion was in the lungs in 87% of patients, and 1 patient in the breast and 1 in esophagus. Pathological classification of the primary lesion was Grade 2 (MIB-1: 3–20% in 1 patient and neuroendocrine carcinoma (MIB-1: ≥21% in 14 patients. The median period from onset of the primary lesion up to diagnosis of brain metastasis was 12.8 months. About 33% of patients had a single metastasis whereas 67% patients had multiple metastases. Brain metastasis was extirpated in 33% of patients. Stereotactic radiotherapy alone was administered in 20% of patients, and brain metastasis was favorably controlled in most of the patients with coadministration of cranial irradiation as appropriate. The median survival period from diagnosis of brain metastasis was 8.1 months. Conclusion: Most of patients with brain metastasis from neuroendocrine carcinoma showed the primary lesion in the lungs, and they had multiple metastases to the liver, lymph nodes, bones, and so forth at the time of diagnosis of brain metastasis. The guidelines for accurate diagnosis and treatment of neuroendocrine carcinoma should be immediately established based on further analyses of those patients with brain metastasis.

    We reviewed several reports of this subtype of HCC. It was known that sarcomatous HCC is hard to be distinguished with ordinary HCC before surgery. There is no evidence that adjuvant therapy including chemotherapy, radiotherapy and target therapy may improve the survival rate. It would usually be diagnosed as atypical HCC and treated as ordinary HCC, however, the prognosis is much worse; this sarcomatosis type HCC should be seriously considered.

    Kim Se


    Full Text Available Abstract Background Pleomorphic adenoma of the lacrimal gland is known to undergo malignant transformation when incompletely excised. Even if such a malignant change occurs, intracranial direct invasion and leptomeningeal seeding are seldom encountered. Case presentation A 50-year-old woman presented with malignant transformation associated with both intracranial invasion and multiple intracranial and spinal disseminations in the third recurrence of pleomorphic adenoma of the lacrimal gland, 6 years after initial treatment. MRI demonstrated increased extent of orbital mass, extending to the cavernous sinus. The patient underwent intensity-modulated radiation therapy (IMRT and Gamma Knife radiosurgery. Follow-up MRI showed multiple leptomeningeal disseminations to the intracranium and spine. Conclusion It is important to recognize that leptomeningeal intracranial and spinal disseminations of pleomorphic adenocarcinoma can occur, although it is extremely rare. To our knowledge, we report the first case of pleomorphic adenocarcinoma of the lacrimal gland presumably metastasizing to the intracranium and spine.

    To evaluate the incidence and risk factors of post-treatment intracranial hemorrhage of brain metastases from hepatocellular carcinoma (HCC). Medical records of 81 patients who have been diagnosed of brain metastases from HCC and underwent surgery, radiosurgery and/or whole brain radiotherapy (WBRT) between January 2000 and December 2013 were retrospectively reviewed. Intracranial hemorrhage was present in 64 patients (79%) at the time of diagnosis. Median value of alpha-fetoprotein (AFP) level was 1,700 ng/mL. The Eastern Cooperative Oncology Group (ECOG) performance status for 20 patients was greater than 2. Fifty-seven patients underwent WBRT and the others were treated with surgery and/or radiosurgery without WBRT. During follow-up, 12 events of intracranial hemorrhage after treatment were identified. Three-month post-treatment hemorrhage rate was 16.1%. Multivariate analyses revealed that ECOG performance status, AFP, and WBRT were associated with post-treatment hemorrhage (p = 0.013, 0.013, and 0.003, respectively). Kaplan-Meier analysis showed that 3-month post-treatment hemorrhage rate of new lesion was higher in patients treated without WBRT, although statistical significance was not reached. (18.6% vs. 4.6%; p = 0.104). Ten of 12 patients with post-treatment hemorrhage died with neurologic cause. WBRT should be considered to prevent post-treatment hemorrhage in the treatment of brain metastases from HCC.

  8. Multidisciplinary Approach to Hepatic Metastases of Intracranial Hemangiopericytoma: A Case Report and Review of the Literature

    Directory of Open Access Journals (Sweden)

    Dimitrios K. Manatakis


    Full Text Available Hemangiopericytoma is a rare primary tumor originating from Zimmerman’s pericytes, with significant metastatic potential. Hepatic metastatic disease requires an aggressive approach by a multidisciplinary team of dedicated oncology specialists, to prolong survival in selected patients. We report on a patient with recurrent hepatic metastases of grade II intracranial hemangiopericytoma 5 years after initial treatment, managed by a stepwise combination of liver resection, radiofrequency ablation, and transarterial embolization. Although metastatic disease implies hematogenous dissemination, long-term survival after liver resection has been reported and major hepatectomies are justified in patients with adequate local control. Liver resections combined with transarterial embolization are highly recommended, due to hypervascularity of the tumor.

    Full Text Available Longitudinal MRI was applied to monitor intracranial initiation and development of brain metastases and assess tumor vascular volume and permeability in a mouse model of breast cancer brain metastases. Using a 9.4T system, high resolution anatomic MRI and dynamic susceptibility contrast (DSC perfusion MRI were acquired at different time points after an intracardiac injection of brain-tropic breast cancer MDA-MB231BR-EGFP cells. Three weeks post injection, multifocal brain metastases were first observed with hyperintensity on T2-weighted images, but isointensity on T1-weighted post contrast images, indicating that blood-tumor-barrier (BTB at early stage of brain metastases was impermeable. Follow-up MRI revealed intracranial tumor growth and increased number of metastases that distributed throughout the whole brain. At the last scan on week 5, T1-weighted post contrast images detected BTB disruption in 160 (34% of a total of 464 brain metastases. Enhancement in some of the metastases was only seen in partial regions of the tumor, suggesting intratumoral heterogeneity of BTB disruption. DSC MRI measurements of relative cerebral blood volume (rCBV showed that rCBV of brain metastases was significantly lower (mean= 0.89±0.03 than that of contralateral normal brain (mean= 1.00±0.03; p<0.005. Intriguingly, longitudinal measurements revealed that rCBV of individual metastases at early stage was similar to, but became significantly lower than that of contralateral normal brain with tumor growth (p<0.05. The rCBV data were concordant with histological analysis of microvascular density (MVD. Moreover, comprehensive analysis suggested no significant correlation among tumor size, rCBV and BTB permeability. In conclusion, longitudinal MRI provides non-invasive in vivo assessments of spatial and temporal development of brain metastases and their vascular volume and permeability. The characteristic rCBV of brain metastases may have a diagnostic value.

  10. Rapid progression of intracranial melanoma metastases controlled with combined BRAF/MEK inhibition after discontinuation of therapy: a clinical challenge. (United States)

    N Cagney, Daniel; Alexander, Brian M; Hodi, F Stephen; Buchbinder, Elizabeth I; Ott, Patrick A; Aizer, Ayal A


    Novel systemic therapies with anti-tumor activity in the brain including small molecules targeting BRAF and MEK, and immune checkpoint inhibition, offer the possibility of improved control of intracranial disease. A number of prospective trials support the judicious use of modern systemic therapies in patients with melanoma and limited brain metastases .The intracranial clinical course of patients who progress extracranially on BRAF/MEK inhibition remains poorly described in the literature. In this report, we highlight a series of clinical cases, with rapid progression of intracranial disease following discontinuation of dabrafenib/trametinib for extracranial disease progression or toxicity, a previously unreported finding in the medical literature with significant implications for patient care.

  11. Intracranial Tumor Cell Migration and the Development of Multiple Brain Metastases in Malignant Melanoma

    Directory of Open Access Journals (Sweden)

    Trude G. Simonsen


    Full Text Available INTRODUCTION: A majority of patients with melanoma brain metastases develop multiple lesions, and these patients show particularly poor prognosis. To develop improved treatment strategies, detailed insights into the biology of melanoma brain metastases, and particularly the development of multiple lesions, are needed. The purpose of this preclinical investigation was to study melanoma cell migration within the brain after cell injection into a well-defined intracerebral site. METHODS: A-07, D-12, R-18, and U-25 human melanoma cells transfected with green fluorescent protein were injected stereotactically into the right cerebral hemisphere of nude mice. Moribund mice were killed and autopsied, and the brain was evaluated by fluorescence imaging or histological examination. RESULTS: Intracerebral inoculation of melanoma cells produced multiple lesions involving all regions of the brain, suggesting that the cells were able to migrate over substantial distances within the brain. Multiple modes of transport were identified, and all transport modes were observed in all four melanoma lines. Thus, the melanoma cells were passively transported via the flow of cerebrospinal fluid in the meninges and ventricles, they migrated actively along leptomeningeal and brain parenchymal blood vessels, and they migrated actively along the surfaces separating different brain compartments. CONCLUSION: Migration of melanoma cells after initial arrest, extravasation, and growth at a single location within the brain may contribute significantly to the development of multiple melanoma brain metastases.

  12. Intracranial malignant meningioma with multiple spinal metastases--a case report and literature review: case report. (United States)

    Chuang, Hao-Che; Lee, Han-Chung; Cho, Der-Yang


    Case report. To report a case and review the literature on intracranial malignant meningioma with metastasis to the spine. Because so few cases have been recognized and reported, the radiologic and pathologic assessment, pathway of metastasis, and the concepts of surgical resection and other palliative management of this disease are still controversial. A big lobulated mass in the left frontal lobe containing calcifications and tumor bleeding was resected. Pathologic findings indicated malignant meningioma due to bone destruction and dura invasion grossly, and tumor cellular atypism with mitotic activity and massive tumor necrosis microscopically. Radiotherapy followed, and brain computed tomography revealed no definite evidence of recurrence. Three months later, spinal magnetic resonance imaging revealed multiple bone metastasis in lower T-L-S1, and pathologic fracture of L1 with compression of the dural sac and spinal cord. Surgical resection was done for decompression, fixation, and pathologic proof. Both pathologic and immunohistochemical survey found evidence consistent with malignant meningioma with spinal metastasis. Advanced treatment was refused, and the patient died. Spinal magnetic resonance imaging should be performed because of the high spinal metastatic rate, especially when spinal symptoms and signs are present. Immunohistochemical study has an important role in the differential diagnosis of primary or metastatic intracranial neoplasms.

  13. EGFR mutations are associated with favorable intracranial response and progression-free survival following brain irradiation in non-small cell lung cancer patients with brain metastases (United States)


    Background The presence of epidermal growth factor receptor (EGFR) mutations in non-small cell lung cancer (NSCLC) is associated with increased radiosensitivity in vitro. However, the results from clinical studies regarding the radiosensitivity in NSCLC with mutant EGFR are inconclusive. We retrospectively analyzed our NSCLC patients who had been regularly followed up by imaging studies after irradiation for brain metastases, and investigated the impact of EGFR mutations on radiotherapy (RT). Methods Forty-three patients with brain metastases treated with RT, together with EGFR mutation status, demographics, smoking history, performance status, recursive partitioning analysis (RPA) class, tumor characteristics, and treatment modalities, were included. Radiological images were taken at 1 to 3 months after RT, and 3 to 6 months thereafter. Radiographic response was evaluated by RECIST criteria version 1.1 according to the intracranial images before and after RT. Log-rank test and Cox regression model were used to correlate EGFR mutation status and other clinical features with intracranial radiological progression-free survival (RPFS) and overall survival (OS). Results The median follow-up duration was 15 months. Patients with mutant EGFR had higher response rates to brain RT than those with wild-type EGFR (80% vs. 46%; p = 0.037). Logistic regression analysis showed that EGFR mutation status is the only predictor for treatment response (p = 0.032). The median intracranial RPFS was 18 months (95% CI = 8.33-27.68 months). In Cox regression analysis, mutant EGFR (p = 0.025) and lower RPA class (p = 0.026) were associated with longer intracranial RPFS. EGFR mutation status (p = 0.061) and performance status (p = 0.076) had a trend to predict OS. Conclusions Mutant EGFR in NSCLC patients is an independent prognostic factor for better treatment response and longer intracranial RPFS following RT for brain metastases. PMID:23110940

  14. Meningeal Hemangiopericytoma with Intracranial Metastases in an HIV-Positive Male: Case Report and Review of the Literature

    Directory of Open Access Journals (Sweden)

    Zachary Beatty


    Full Text Available Background: Meningeal hemangiopericytoma is a rare, aggressive CNS tumor that tends to invade locally, metastasize, and has a high rate of recurrence. HIV classically increases the risk of 3 AIDS-defining malignancies: Kaposi’s sarcoma, non-Hodgkin’s lymphoma and invasive cervical cancer. More recently, considerable interest has been paid to the link between HIV and a wider range of non-AIDS-defining cancers. An HIV-positive patient with meningeal hemangiopericytoma is described. Case Description: A 36-year-old HIV-positive male presented with worsening headache and ataxia. The patient had experienced similar neurologic symptoms 4 months prior and MRI at that time had showed an extra-axial left cerebellar mass most consistent with benign meningioma. Repeat MRI showed the tumor had increased in size by a factor of greater than 20 in this 4-month period, with 4 small additional foci of similar enhancement. Subtotal resection was performed on the mass and final pathological diagnosis was meningeal hemangiopericytoma. Conclusions: This represents the first reported case of meningeal hemangiopericytoma in an HIV-positive patient. This is also the shortest time to intracranial metastasis ever reported for a meningeal hemangiopericytoma. Although the increased risk in the HIV-positive population of non-AIDS-defining cancers that has been observed in recent years can largely be attributed to cancers with a known viral pathogenesis, it is speculated that HIV infection in this patient may have contributed to the occurrence or unique behavior of this rare tumor.

    presented. The patient was a 62-year-old man who complained of a foreign body sensation. Endoscopic examination revealed a large pedunculated mass arising from the posterior wall of the mesopharynx. The lesion was surgically resected, using a cutting snare by the endo-oral approach, and was completely removed. A diagnosis of squamous cell carcinoma with sarcomatous stroma was made histopathologically. The clinicopathological features of this case are described and compared with those of previously reported cases.

  17. Rapid sarcomatous transformation of an ameloblastic fibroma of the mandible: case report and literature review. (United States)

    Kousar, Aisha; Hosein, Mervyn M; Ahmed, Zubair; Minhas, Khurram


    Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic tumour regarded as the malignant counterpart of ameloblastic fibroma. It is characterized by a benign epithelial component within a malignant fibrous stroma. AFS is a locally aggressive neoplasm with extremely low potential for metastasis. We report an extremely rare, rapidly progressive, and fatal case originating in the posterior mandible of a 20-year old female patient. Initially histopathologically diagnosed as a benign lesion, it rapidly recurred with apparent transformation into a high-grade sarcoma over a period of 6 months. Subsequent intracranial and pulmonary metastases were noted, and the patient died within 15 months of initial consultation. This case emphasizes the need for a high element of suspicion about clinically ambiguous lesions. We recommend more extensive or radical, primary excisions in lesions that have a known potential for recurrence or malignancy.

  18. Mullerian adenosarcoma (heterologous) of the cervix with sarcomatous overgrowth: a case report with review of literature (United States)

    Nijhawan, Raje; Aggarwal, Neelam; Sikka, Pooja


    Mullerian adenosarcoma is a rare biphasic malignant neoplasm of the cervix characterized by an admixture of benign epithelial elements and a malignant sarcomatous stromal component, which may be either homologous or heterologous. An aggressive variant of adenosarcoma, mullerian adenosarcoma with sarcomatous overgrowth (MASO) is extremely rare, with only two such cases being reported in the English literature to date. In this report we present a case of MASO of uterine cervix with heterologous elements in a 15-year-old unmarried girl presenting with foul smelling menstrual bleeding and passage of fleshy masses. Because MASO with heterologous elements seems to appear at the earliest stages of reproductive lifespan in women, and have an uncertain malignant potential, gynecologists and pathologists should be aware and think about the possibility of this tumor.

  20. An unusual presentation of dermatofibrosarcoma protuberans with pleomorphic sarcomatous transformation: potential pitfall and diagnostic strategy. (United States)

    Cesinaro, Anna Maria; Mataca, Ema; Gambini, Claudio; Kutzner, Heinz


    Dermatofibrosarcoma protuberans (DFSP) is a low grade, superficial sarcoma characterized by a proliferation of monomorphous, spindle cells arranged in a storiform pattern and infiltrating the subcutaneous tissue. The tumor is typically CD34 positive, and shows the characteristic COL1A1-PDGFB fusion gene, detectable either by florescent in situ hybridization (FISH) and polymerase chain reaction (PCR). We describe a case of DFSP with a focus of peculiar pleomorphic sarcomatous transformation. The focus constituted the entire bioptic tissue that was initially excised, raising considerable diagnostic problems for pathologist. The use of FISH as an ancillary technique allowed the right diagnosis.

  1. AB047. The challenges in the diagnosis of sarcomatous mesothelioma—a case report (United States)

    Stathakis, Eustathios; Kilmpasani, Maria; Cheva, Angeliki; Dimitriadis, Ioannis; Pastelli, Nikoleta; Papaemmanouil, Styliani


    Background To report the case of a male patient, 65, who presented with a mass of the left lower lobe of the lung, incidentially found during a CT scan of the thorax. Methods At first, we received bioptic material, following CT-guided biopsy, and, secondly, we received a surgical specimen of left lower lobectomy of the lung. Results The bioptic material consisted of 2 tissue cylinders, 1.6 cm in total length. The microscopic examination revealed scattered cells with severe atypia, within desmoplastic stroma. Necrotic areas and an increased number of mitoses were observed. Immunohistochemistry showed a positive expression for CK8/18, CK7 and Vimentin, while Calretinin and WT-1 were only lightly and focally expressed. Negative staining was observed for CK5/6, CD56, TTF-1, BerEP4 and Napsin. The surgical specimen consisted of a lung lobe, 10×8×8 cm, with a peripheral mass, 3.5 cm in greatest diameter. The microscopic study confirmed the presence of a malignant neoplasm, consisting mainly of spindle cells, with pleomorphy and nuclear atypia, in compact growth pattern. Necrosis was present. The neoplasm infiltrated the pulmonary parenchyma, as well as the skeletal muscles and fat tissue of the parietal pleura. An inflammatory stromal reaction involved mainly lymphocytes and plasmocytes. The immunohistochemical findings were similar to the previous ones, with the exception of Calretinin and WT-1, which were better expressed this time. The proliferation marker Ki67 was positive in 30% of the neoplastic cells. According to these findings, the diagnosis was sarcomatous mesothelioma. Conclusions The diagnosis of sarcomatous mesothelioma, especially in bioptic tissue material, can be problematic. Immunohistochemical stains that are frequently used for epithelial mesothelioma, may not have the same results for the sarcomatous subtype. The differential diagnosis includes a malignant mesenchymal neoplasm (sarcoma) and sarcomatoid carcinoma. Positive cytokeratin staining is

  3. Squamous cell carcinoma with sarcomatous stroma in the nasal cavity of a dog. (United States)

    Bosward, K L; Kessell, A E; Lucy, R J


    This is a report of an unusual squamous cell carcinoma in the nasal cavity of a dog. A 13-year-old Golden Retriever was presented with a unilateral nasal and ocular discharge. Although a nasal tumour was suspected, initial diagnostic investigations were unrewarding, and, with worsening clinical signs, the dog was euthanatized. Necropsy examination confirmed the presence of a nasal tumour that was composed histologically of both a well-differentiated squamous cell carcinoma component blending with a predominant spindle cell component. Immunohistochemical staining with anti-human keratin/cytokeratin (AE1/AE3, CAM 5.2 and broad spectrum cytokeratin), Vimentin, Desmin, smooth muscle actin and S-100 protein supported a diagnosis of a squamous cell carcinoma with (pseudo) sarcomatous stroma.

    Refaat, Tamer; Sachdev, Sean; Desai, Brijal; Bacchus, Ian; Hatoum, Saleh; Lee, Plato; Bloch, Orin; Chandler, James P; Kalapurakal, John; Marymont, Maryanne Hoffman


    Brain metastases are the most common intracranial tumors in adults, accounting for over half of all lesions. Whole-brain radiation therapy (WBRT) has been a cornerstone in the management of brain metastases for decades. Recently, stereotactic radiosurgery (SRS) has been considered as a definitive or postoperative approach instead of WBRT, to minimize the risk of cognitive impairment that may be associated with WBRT. This is the case report of a 74-year-old female patient who was diagnosed with lung cancer in November, 2002, and histopathologically confirmed brain metastases in January, 2005. The patient received 5 treatments with Gamma Knife SRS for recurring brain metastases between 2005 and 2014. The patient remains highly functional, with stable intracranial disease at 10 years since first developing brain metastases, and with stable lung disease. Therefore, Gamma Knife SRS is a safe and effective treatment modality for patients with recurrent intracranial metastases, with durable local control and minimal cognitive impairment.

    Full Text Available Ependymoma are rare glial neoplasm, it rarely metastasize outside the central nervous system. We present a case of anaplastic ependymoma with extraneural metastases with review of literature. A ten-year-old male child presented with anaplastic ependymoma of choroid plexus and treated with craniospinal radiotherapy in 1998. He had intracranial recurrence in 2004, confirmed by biopsy. He was given adjuvant chemotherapy in form of PCV. At 10 months after completion of chemotherapy, he developed extracranial scalp metastasis and so was treated with palliative local radiation therapy to the scalp metastasis and systemic chemotherapy with oral Etoposide. Scalp metastasis completely disappeared and ataxia improved. After five cycles of chemotherapy, the patient had progression of disease in form of scalp and cervical lymph node metastasis confirmed by fine needle aspiration cytology, biopsy and immunohistochemistry. He was given salvage chemotherapy (carboplatin + ifosfamide + etoposide at 3-weekly. He had partial response and was still on chemotherapy till May 2007.

    Gonzalez-Vitale, J.C.; Slavin, R.E.; McQueen, J.D.


    An autopsy case of radiation-induced intracranial malignant fibrous histiocytoma (fibroxanthosarcoma) is reported. The tumor developed in the region of the sella turcica 11 years after high dose radiotherapy of a chromophobe adenoma of the pituitary. The tumor had infiltrated the base of the brain as well as the base of the skull. Metastases were not found. The tumor was composed of an admixture of bizarre fibroblasts, histiocytes and giant cells, xanthoma cells and siderophages, with a storiform fibrous stroma. This appears to be the first documented instance of a malignant fibrous histiocytoma occurring intracranially after local x irradiation.

  9. Sarcomatous transformation of osteochondroma of the coronoid process forming pseudoarthrosis with zygomatic arch mistaken for Jacob disease. (United States)

    Jha, Abhishek; Gupta, Prakhar; Khalid, Mohd; Naseem, Iqbal; Gupta, Gagan


    Osteochondromas are the most common benign osseous neoplasms, with a propensity to involve long bones. The involvement of the coronoid process is extremely rare, and osteochondromas of the coronoid process may form pseudoarticulations with the zygomatic arch when large, an entity that is extremely rare and termed as Jacob disease. Sarcomatous degeneration of osteochondroma of the coronoid process is an extremely rare entity and has not been described to date. Only 1 case of primary mesenchymal chondrosarcoma has been described. We present a case of a 24-year-old man with a chondrosarcoma of the coronoid process, who was wrongly diagnosed with Jacob disease on the basis of radiologic findings.

  10. Intracranial endoscopy. (United States)

    Schroeder, H W; Gaab, M R


    The authors' intention is to reduce the invasiveness of intracranial procedures while avoiding traumatization of brain tissue, to decrease the risk of neurological and mental deficits. Intracranial endoscopy is a minimally invasive technique that provides rapid access to the target via small burr holes without the need for brain retraction. Craniotomy as well as microsurgical brain splitting and dissection can often be avoided. Furthermore, because obstructed cerebrospinal fluid pathways can be physiologically restored, the need for shunt placement is eliminated. The ventricular system and subarachnoid spaces provide ideal conditions for the use of an endoscope. Therefore, a variety of disorders, such as hydrocephalus, small intraventricular lesions, and arachnoid and parenchymal cysts can be effectively treated using endoscopic techniques. With the aid of special instruments, laser fibers, and bipolar diathermy, even highly vascularized lesions such as cavernomas may be treated. Moreover, during standard microsurgical procedures, the endoscopic view may provide valuable additional information ("looking around a corner") about the individual anatomy that is not visible with the microscope. In transsphenoidal pituitary surgery, transseptal dissection can be avoided if an endonasal approach is taken. In the depth of the intrasellar space, the extent of tumor removal can be more accurately controlled, especially in larger tumors with para- and suprasellar growth. The combined use of endoscopes and computerized neuronavigation systems increases the accuracy of the approach and provides real-time control of the endoscope tip position and approach trajectory. In the future, the indications for neuroendoscopy will certainly expand with improved technical equipment.

    Objective To study the value of different MR sequences in monitoring intracranial metastases of lung cancer using 3.0 T MR scanner. Methods 11 patients with brain metastases of primary lung cancer underwent MRI examination including T1 WI,T2 WI, T2 FLAIR, DWI, contrast-enhanced T1 WI sequences. Of them, 4 cases underwent DTI scan, 3 patients underwent SWI scan. The location of metastatic tumors, signal characteristics, the detecting rate of tumors with different sequences, the rADC value of metastatic tumor and normal brain were analysed. Results The metastatic tumors of the brain most located in the junctional zone of cerebral gray-white matter, 73.5 % located in supratentorial region and 24.7% in infratentorial region. The enhanced patterns of metastases at contrast-enhanced MR imaging were nodular (80.7 %) and ring( 16.3 %). Compared with other sequences, T1 WI enhancement had the highest detecting rate. The rADC value of metastatic substantial part, edema part, normal contralateral brain were( 126.5 ± 28.2) %, (159.3± 42.1) %, 100 % respectively and there was statistically significance difference between them (P<0. 05). 3 cases on SWI, the lesions showed relatively low signal areas which were smaller than those in enhanced MRI images. 4 cases on DTI, the white matter tracts of metastatic region displayed shift and infiltration. Conclusion High field MR has advantages for the detection of intracranial metastases of lung cancer. T1 WI enhancement is best sequence to find metastases. DWI, DTI and SWI are helpful for the diagnosis and evaluation of brain metastases.%目的 探讨3.0T MR不同序列对肺癌脑转移的诊断价值.方法 回顾性分析本院经病理确诊为肺癌并经临床诊断为脑转移瘤的11例患者,所有病例均行常规T1WI、T2WI、T2 FLAIR、DWI、T1WI增强MR检查;其中4例行DTI检查;3例行SWI检查.对转移瘤的部位、信号特点、不同序列病灶的检出率、转移瘤与正常脑实质

  16. Implications of Identifying Additional Cerebral Metastases during Gamma Knife Radiosurgery

    Directory of Open Access Journals (Sweden)

    Toral R. Patel


    Full Text Available Introduction. Gamma Knife radiosurgery (GK-SRS is commonly used to treat cerebral metastases. Although additional intracranial metastases are often found on the day of GK-SRS, the significance of finding them is unknown. Methods. A retrospective review of 133 patients undergoing GK-SRS for cerebral metastases was performed. The change in number of metastases detected between initial referral magnetic resonance imaging (MRI and subsequent treatment MRI was quantified. Multivariate and Kaplan-Meier analyses were employed to examine the significance of identifying additional lesions. Results. Additional lesions were identified in 41% of patients. An increasing number of metastases on referral MRI (=0.001 and the presence of progressive systemic disease (=0.003 were predictive of identifying additional metastases. Median survival was 6.9 months for patients with additional metastases, compared to 12.1 months for patients without additional metastases (hazard ratio 1.56, =0.021. Conclusions. Identifying additional metastases on the day of GK-SRS may add important prognostic information.

  17. Intracranial aneurysms. (United States)

    Puskar, G; Ruggieri, P M


    MR angiography provides a rapid, accurate, and extremely flexible noninvasive evaluation of intracranial aneurysms without the cost and risk of conventional angiography. TOF and phase contrast techniques each have specific advantages and disadvantages that can be selectively exploited to optimize aneurysm evaluation. Present indications for MR angiography in aneurysm evaluation include: (1) the presence of incidental findings on a CT or MR examination that suggest the possibility of aneurysm (Figs. 7 and 8), (2) when angiography is contraindicated or when the risk is too high, (3) non-invasive follow-up of patients with known aneurysms, (4) patient refusal of contrast angiography, and (5) evaluation of patients with specific clinical symptoms (i.e., third cranial nerve palsy) or patients with non-specific subacute symptoms in whom an aneurysm might explain the clinical presentation. Although MR angiography certainly can detect aneurysms with a high rate of sensitivity and specificity, detailed decision analyses generally have not supported the overall benefit of this type of screening. Future technical advances as well as advances in the overall understanding of aneurysms may one day prove unequivocally the benefit of MR angiography in screening high-risk patient groups. MR angiography has not yet been clinically evaluated as a tool in the evaluation of acute subarachnoid hemorrhage. Potential obstacles to such an evaluation include the clinical instability of SAH patients, limited spatial resolution of the MR angiography acquisitions, the potential for subarachnoid blood or focal intraparenchymal hematomas to obscure or mimic small aneurysms, and the unreliability of MR angiography in demonstrating vasospasm. Currently these factors continue to provide an integral role for contrast angiography in aneurysm evaluation.

  18. Intracranial manifestations of malignant lymphomas

    Energy Technology Data Exchange (ETDEWEB)

    Galanski, M.; Fahrendorf, G.; Urbanitz, D.; Beckmann, A.; Elger, C.


    Approximately 10% of patients with malignant lymphoma will show neurological symptoms at some time during the course of their illness. In non-Hodgkin lymphoma, CNS involvement is more frequent than in Hodgkin's disease. Diffuse histiocytic and poorly differentiated lymphomas, bone marrow involvement, advanced tumor stage and hematogenous spread are particular risk factors. Invasion of the spinal canal is the most common type of CNS involvement. Intracranial lesions, which are comparatively rare, may present as intracerebral metastases, epi- or subdural masses or focal or diffuse leptomeningeal disease. Lymphomatous leptomeningitis usually cannot be demonstrated by CT. On the other hand, dural and cerebral parenchymal lesions are sometimes highly characteristic of lymphoma as a result of their features and location.

  19. The Treatment of Melanoma Brain Metastases. (United States)

    Kibbi, Nour; Kluger, Harriet


    Melanoma is the malignancy with the highest rate of dissemination to the central nervous system once it metastasizes. Until recently, the prognosis of patients with melanoma brain metastases (MBM) was poor. In recent years, however, the prognosis has improved due to high-resolution imaging that facilitates early detection of small asymptomatic brain metastases and early intervention with local modalities such as stereotactic radiosurgery. More recently, a number of systemic therapies have been approved by the Food and Drug Administration for metastatic melanoma, resulting in improved survival for many MBM patients. Registration trials for these newer therapies excluded patients with untreated brain metastases, and a number of studies specifically tailored to this population of patients have been conducted or are underway. Herein, we review contemporary locoregional and systemic therapies and describe the unique challenges posed by treatment of brain metastases, such as radionecrosis, cerebral edema, and pseudoprogression. Since the number of systemic and combined modality clinical trials has increased, we expect that the treatment landscape for patients with melanoma brain metastasis will change dramatically. In addition to ongoing clinical trials, which show great promise, we conclude that our understanding of intracranial metastasis remains quite limited. In addition to inter-disciplinary, multi-modality studies, bench-side work to better understand the process of cerebrotropism is needed to fuel more drug development and further improve outcomes.

    Gazit, Inbal; Har-Nof, Sagi; Cohen, Zvi R; Zibly, Zion; Nissim, Uzi; Spiegelmann, Roberto


    The objective of this study was to assess reduction in cerebral edema following linear accelerator radiosurgery (LINAC) as first line therapy for brain metastasis. We reviewed the medical records of all patients who underwent LINAC radiosurgery for brain metastasis at our institution during 2010-2012, and who had not previously undergone either surgery or whole brain radiotherapy. Data were analyzed for 55 brain metastases from 46 patients (24 males), mean age 59.9 years. During the 2 months following LINAC radiosurgery, the mean steroid dose decreased from 4.8 to 2.6 mg/day, the mean metastasis volume decreased from 3.79±4.12 cc to 2.8±4.48 cc (p=0.001), and the mean edema volume decreased from 16.91±30.15 cc to 12.85±24.47 cc (p=0.23). The 17 patients with reductions of more than 50% in brain edema volume had single metastases. Edema volume in the nine patients with two brain metastases remained stable in five patients (volume change 10%, 2-14 cc). In a subanalysis of eight metastases with baseline edema volume greater than 40 cc, edema volume decreased from 77.27±37.21 cc to 24.84±35.6 cc (p=0.034). Reductions in brain edema were greater in metastases for which non-small-cell lung carcinoma and breast cancers were the primary diseases. Overall, symptoms improved in most patients. No patients who were without symptoms or who had no signs of increased intracranial pressure at baseline developed signs of intracranial pressure following LINAC radiosurgery. In this series, LINAC stereotactic radiosurgery for metastatic brain lesions resulted in early reduction in brain edema volume in single metastasis patients and those with large edema volumes, and reduced the need for steroids.

    Rajeev Kumar


    Full Text Available Background: Intracranial endoscopy is a minimum invasive procedure, which reduces trauma to the brain, is cost-effective, and carries a shortened hospital stay with an improved postoperative outcome. Objective: To monitor intracranial pressure changes during intracranial endoscopy among children and adults under general anesthesia/sedation, and to compare the intracranial pressure changes between children and adults receiving general anesthesia and among adults receiving general anesthesia and sedation. Methods: The present cross-sectional study was conducted in one of the tertiary care hospitals of Lucknow. This was carried out in the department of neurosurgery from January 2008 to December 2008. Patients who were not fit for general anesthesia received local anesthesia under sedation. Patients participating in the study were divided into three groups. Intracranial pressure was recorded at specific intervals. Parametric data were subjected to statistical analysis using a student\\s t test. Result: A total of 70 patients were undergoing intracranial endoscopy under general anesthesia during the study period. In both groups A and B, intracranial pressure increases the maximum during inflation of the balloon. In group C, all the variations in ICP were found to be statistically significant. In the comparison of intracranial pressure changes between groups A and B, no significant difference was found. All correlations in the comparison of groups B and C were found to be statistically significant (p< 0.001. Conclusion: There is a need for continuous intraoperative monitoring of ICP intracranial endoscopy, because ICP increases in various stages of the procedure, which can be detrimental to the perfusion of the brain.

  2. Nontraumatic intracranial hemorrhage. (United States)

    Fischbein, Nancy J; Wijman, Christine A C


    Nontraumatic (or spontaneous) intracranial hemorrhage most commonly involves the brain parenchyma and subarachnoid space. This entity accounts for at least 10% of strokes and is a leading cause of death and disability in adults. Important causes of spontaneous intracranial hemorrhage include hypertension, cerebral amyloid angiopathy, aneurysms, vascular malformations, and hemorrhagic infarcts (both venous and arterial). Imaging findings in common and less common causes of spontaneous intracranial hemorrhage are reviewed.

    Sumit Thakar


    Full Text Available Intracranial occurrence of Ewing sarcoma (ES is unusual, with a skull-base location being anecdotal. We report a 29-year-old man who presented with rapidly progressive ophthalmoplegia, and was found to be harboring an infiltrative lesion involving the sphenoid sinus, sella, and clivus. He underwent trans-sphenoidal decompression of the lesion which was histologically suggestive of ES. He developed paraparesis 2 weeks after commencing adjuvant therapy. Imaging revealed two thoracic extradural lesions and florid vertebral and pulmonary metastases. This is the first report in indexed literature of a primary intracranial ES on the skull-base with disseminated extracranial disease.

    Between February 1992 and April 1993, six patients with lung cancer were treated with gamma knife radiosurgery for brain metastases. Five patients had adenocarcinoma, and one patient had small cell carcinoma. Two patients had solitary metastases, and four patients had multiple metastases. Twelve metastases were treated with the gamma knife (peripheral dose between 12 Gy and 25 Gy). After radiosurgery, three complete and eight partial responses were achieved, which resulted in an overall response rate of 92%. In two patients, histological studies showed that few viable cells were surrounded by necrosis. Neurological status improved in all patients, and none died of complications. However, four of six patients later developed new intracranial metastases outside the treatment field. These data suggest that radiosurgery with the gamma knife is effective against brain metastases in patients with lung cancer, especially when the lesions are deep in the brain. (author).

    Full Text Available Intracranial aneurysms in childhood account for 1-2% of intracranial aneurysms.[1],[2] These aneurysms have unique characteristics that make them different from those in adults. These differences are evident in their epidemiology, location, clinical spectrum, association with trauma and infection, complications and outcome.

  9. Intracranial microcapsule chemotherapy delivery for the localized treatment of rodent metastatic breast adenocarcinoma in the brain. (United States)

    Upadhyay, Urvashi M; Tyler, Betty; Patta, Yoda; Wicks, Robert; Spencer, Kevin; Scott, Alexander; Masi, Byron; Hwang, Lee; Grossman, Rachel; Cima, Michael; Brem, Henry; Langer, Robert


    Metastases represent the most common brain tumors in adults. Surgical resection alone results in 45% recurrence and is usually accompanied by radiation and chemotherapy. Adequate chemotherapy delivery to the CNS is hindered by the blood-brain barrier. Efforts at delivering chemotherapy locally to gliomas have shown modest increases in survival, likely limited by the infiltrative nature of the tumor. Temozolomide (TMZ) is first-line treatment for gliomas and recurrent brain metastases. Doxorubicin (DOX) is used in treating many types of breast cancer, although its use is limited by severe cardiac toxicity. Intracranially implanted DOX and TMZ microcapsules are compared with systemic administration of the same treatments in a rodent model of breast adenocarcinoma brain metastases. Outcomes were animal survival, quantified drug exposure, and distribution of cleaved caspase 3. Intracranial delivery of TMZ and systemic DOX administration prolong survival more than intracranial DOX or systemic TMZ. Intracranial TMZ generates the more robust induction of apoptotic pathways. We postulate that these differences may be explained by distribution profiles of each drug when administered intracranially: TMZ displays a broader distribution profile than DOX. These microcapsule devices provide a safe, reliable vehicle for intracranial chemotherapy delivery and have the capacity to be efficacious and superior to systemic delivery of chemotherapy. Future work should include strategies to improve the distribution profile. These findings also have broader implications in localized drug delivery to all tissue, because the efficacy of a drug will always be limited by its ability to diffuse into surrounding tissue past its delivery source.

  11. Sarcomatous evolution of oligodendroglioma ("oligosarcoma"): confirmatory report of an uncommon pattern of malignant progression in oligodendroglial tumors. (United States)

    Vajtai, Istvan; Vassella, Erik; Hewer, Ekkehard; Kappeler, Andreas; Reinert, Michael M


    By analogy to gliosarcoma, the neologism "oligosarcoma" is to describe an uncommon form of biphasic central nervous system tumor composed of contiguous neuroepithelial and mesenchymal elements, each of which individually meet the criteria of oligodendroglioma and sarcoma, respectively. By virtue of its distinctive genotype (codeletion 1p/19q), oligodendroglioma is a particularly inviting paradigm to test the assumption that such mixed tumors are clonally derived from a glial primary. We observed this constellation in a 41-year-old male who underwent two resection procedures for a recurring right frontal tumor at five years' interval. On imaging, both lesions were contrast-enhancing, and measured 7 cm × 7 cm × 6.8 cm and 7 cm × 6.5 cm × 4cm, respectively. Following the first operation, temozolomide monotherapy was administered. Whereas initial histology showed conventional anaplastic oligodendroglioma, the recurrence consisted mostly of a fibrosarcoma-like, fascicular neoplasm that was immunoreactive for vimentin, smooth muscle actin, S100 protein, and focally epithelial membrane antigen. In between, a subset of otherwise indistinguishable spindle cells expressed GFAP, and focally merged with residues of oligodendroglioma. Molecular testing for loss of heterozygosity confirmed codeletion of 1p/19q in both the primary tumor and the sarcomatous recurrence. Similarly, generalized immunoreactivity for the mutant R132H form of isocitrate dehydrogenase in both lesions indicated an identical mutation of the IDH1 gene. By the above standards, biologically consistent "oligosarcomas" are felt to be exceedingly rare, and possibly participate of a nosologically heterogeneous group of combined glial/mesenchymal lesions that may also include iatrogenically induced second malignancies as well as true collision tumors.

    Woodroffe, Royce W; Abel, Taylor J; Fletcher, Aaron; Grossbach, Andrew; Van Daele, Douglas J; O'Brien, Erin; Greenlee, Jeremy D W


    Ameloblastoma is a rare odontogenic tumor with characteristics of epithelial tissue that produces enamel for the developing tooth. This lesion is generally considered benign, but has malignant forms that invade locally and metastasize. We present a 60-year-old man with maxillary ameloblastoma that after multiple recurrences developed intracranial extension with dural involvement of the middle cranial fossa and was treated by endoscopic transnasal resection followed by radiation therapy. Our technique and intraoperative findings are described with a review of the literature on intracranial ameloblastoma. This patient represents a unique account of endoscopic transnasal resection being utilized in the treatment of intracranial extension of ameloblastoma and demonstrates potential for application in similar cases.

    Full Text Available Background: Isolated adrenal gland metastases are not frequently finding. The aim of the present retrospective study was to estimate clinical and pathological parameters that could be used to predict survival after adrenalectomy. Material and methods: A total of 34 patients with adrenal gland masses suspected to be metastases was included in this study. The group of patients with isolated metastases was19 (56% and a group of patients with adrenal adenomas -15 (44%. Results: The sample of patients consisted of 18 (53% men and 16 (47% women from 40 to 81 years old with a mean (±SD age of 61.6±10.3 years, presented with adrenal mass suspected to be metastases. Nineteen (56% of them had demonstrated metastases and 16 (84% metachronous with median overall survival (OS 54.6 (range 43-66 months. Median OS in the group with metastases was 22.6 months. Lung carcinoma was the most common primary tumour metastasizing in the adrenal gland – 58% of all metastases with a disease-free interval (DFI of 13 months. It was presented by shorter median survival than the rest primary tumour types (37.8 vs. 96.7months; log-rank test, p=0.028. In the multivariate Cox’s hazard analysis of the surgical technique was found to be an independent prognostic factor (p=0.047, together with lung carcinoma vs. renal cell carcinoma (p=0.045. Conclusion: Adrenalectomy due to isolated metastases in the adrenal glands showed the median overall survival of 22.6 months. Shorter survival periods were associated with lung carcinoma, DFI<12months, conversion to open surgery, synchronous metastases, but not with age, tumour size or resection status.

    Gheorghita, Eva; Pruna, Viorel Mihai; Neagoe, Luminita; Bucur, Cristina; Cristescu, Catioara; Gorgan, Mircea Radu


    ABSTRACT Objective: The present study proposes to present the importance of perioperative therapeutic management in survival prolongation and the quality of life for patients that have undergone surgery for cerebral metastases secondary to pulmonary tumors. Method: During 2001-2009, 40 patients with ages between 43-74 years have been diagnosed in our clinic with pulmonary tumor and cerebral metastases. The patients presented single cerebral lesion (excepting one patient with 2 cerebral metastases) and pulmonary tumor. Intracranial pressure (ICP) was high in all cases. All patients have undergone operation with general anesthesia. Results:For all patients the reduction of ICP and keeping an optimal CPP (cerebral perfusion pressure) was pursued. In 38 cases, general anesthesia was performed with Sevoflurane and opioids (fentanyl, remifentanyl, sufentanyl) and in 2 cases the TIVA (total intravenous anesthesia) technique was used with propofol and remifentanyl. 14 of the patients required intraoperative depletive treatment through administering mannitol 20%. 37 patients (92%) have been discharged with improved neurological condition without showing signs of intracranial hypertension, convulsive seizures and with partially or totally remitted hemiparesis and one patient had worse postoperative neurological status. Conclusion:Pulmonary tumor with cerebral metastases represent an important cause for death rate. To solve secondary cerebral lesions, the perioperative management must include assesment and choosing an anesthesia technique with a proper intraoperative management. PMID:21977115

  15. Radiotherapy for cranial and brain metastases from prostate cancer: a systematic review. (United States)

    Sita, Timothy L; Petras, Katarina G; Wafford, Q Eileen; Berendsen, Mark A; Kruser, Tim J


    Intracranial metastasis from prostate cancer is rare. As treatment of castration-resistant prostate cancer improves, the incidence of men with intracranial metastasis from prostate cancer is increasing. Radiation therapy for treatment of intracranial metastasis from prostate cancer is systematically reviewed. A comprehensive review examining peer-reviewed, English language articles from 1990 to 2015 was performed on multiple databases, yielding 1274 articles. These articles were reviewed and selected for studies that met the following inclusion criteria: (1) patients with intracranial metastases from prostate cancer; (2) patients underwent radiation therapy as primary or adjuvant therapy; (3) the sample size of patients was larger than 2. All studies that met inclusion criteria utilized whole-brain radiation therapy (WBRT) in at least one patient. Other treatment regimens included stereotactic radiosurgery (SRS), surgical resection followed by WBRT, as well as concurrent cabazitaxel and WBRT. The range of average time from initial diagnosis of prostate cancer to diagnosis of brain metastasis was 29-45 months. The range of reported median survival time after WBRT was 4-9 months, whereas median survivals after SRS ranged from 9 to 13 months. Intracranial metastases from prostate cancer occur late in the disease process, and are increasing as novel therapies for metastatic disease prolong survival. The reviewed literature suggests that outcomes of patients with prostate cancer intracranial metastases appear similar to those of intracranial metastases from other histologies. Prospective examinations of systemic therapies that cross the blood-brain barrier in conjunction with targeted radiotherapy appear warranted for this increasingly common clinical problem.

  19. [Correction of intracranial pressure in patients with traumatic intracranial hemorrhages]. (United States)

    Virozub, I D; Chipko, S S; Chernovskiĭ, V I; Cherniaev, V A


    Therapeutical correction of intracranial pressure changes were conducted in 14 patients suffering from traumatic intracranial hematomas by endolumbar administration of physiological solution. The distinguishing feature of this method is the possibility of continuous control of the intracranial pressure level by means of long-term graphic recording of epidural pressure. This makes it possible to perform endolumbar administration of physiological solution in a dose which is determined by the initial level of epidural intracranial pressure. Therapeutic correction of intracranial pressure by endolumbar injection of physiological solution proved successful in the initial stages of dislocation of the brain and in stable intracranial hypotension.

    Three cases of neuroblastoma with intracranial metastases were reported. The first case was a 13-year-old girl with sacral neutroblastoma who had metastases to the left parietal bone and dura, and had bilateral intraorbital metastases. The second case was a 13-year-old girl with mediastinal neutroblastoma who had metastases to the dura at the left middle fossa, and had bilateral intraorbital metastases. The third case was a 49-year-old woman with esthesioneuroblastoma which had invaded to the dura at the right middle fossa and the right orbit. CT findings of the brain of these three cases were investigated, and summarized as follows: 1) The intracranial invasions of the metastatic tumors were seen to be slightly high density (EMI-number 25 - 27) in plain scans, and homogeneously enhanced as a well-defined high density mass (EMI-number 35 - 37). 2) The tumors invading the skull were observed as a mass lesion of the bone on osteolytic lesion. 3) The intraorbital metastatic tumors were seated on the orbital wall invading the rectal muscles, but they remained extraconal. It was emphasized that CT could give valuable information for the diagnosis of skull and intracranial metastasis of neutroblastoma.

    Extra-axial intracranial metastases may arise through several situations. Hematogenous spread to the meninges is the most frequent cause. Direct extension from contiguous extra-cranial neoplasms, secondary invasion of the meninges by calvarium and skull base metastases, and migration along perineural or perivascular structures are less common. Leptomeningeal invasion gives rise to tumour cell dissemination by the cerebrospinal fluid (CSF), eventually leading to neoplastic coating of brain surfaces. Contrast-enhanced magnetic resonance (MR) imaging is complementary to CSF examinations and can be invaluable, detecting up to 50% of false-negative lumbar punctures. MR findings range from diffuse linear leptomeningeal enhancement to multiple enhancing extra-axial nodules, obstructive communicating and non-communicating hydrocephalus. Both calvarial and epidural metastases infrequently transgress the dura, which acts as a barrier against tumour spread. Radionuclide bone studies are still a valuable screening test to detect bone metastases. With computed tomography (CT) and MR, bone metastases extending intracranially and primary dural metastases show the characteristic biconvex shape, usually associated with brain displacement away from the inner table. Although CT is better in detecting skull base erosion, MR is more sensitive and provides more detailed information about dural involvement. Perineural and perivascular spread from head and neck neoplasms require thin-section contrast-enhanced MR. (orig.)

  4. Intracranial tuberculoma: MR imaging

    Energy Technology Data Exchange (ETDEWEB)

    Salgado, P.; Zenteno, M.A.; Rodriguez-Carbajal, J.; Brutto, O.H. del; Talamas, O.


    MR studies of 6 patients with intracranial tuberculoma are reviewed. All patients also underwent CT scans which showed hypo- or isodense lesions with abnormal enhancement following contrast administration. MR showed lesions with prolongation of the T1 relaxation time in every case. On the T2-weighted sequences, the signal properties of the tuberculoma varied according to the stage of evolution of the lesion. Incipient tuberculomas appeared as scattered areas of hypointensity surrounded by edema. Mature tuberculomas were composed of a dark necrotic center surrounded by an isointense capsule which was, in turn, surrounded by edema. In one patient, the center of the lesion was hyperintense probably because of liquefaction and pus formation (tuberculous abscess). While both, CT and MR, were equally sensitive in visualizing the intracranial tuberculoma in every patient, MR was slightly superior in demonstrating the extent of the lesion, especially for brainstem tuberculomas. Nevertheless, the potential role for MR diagnosis of intracranial tuberculoma is limited by the fact that other infectious or neoplasic diseases may present similar findings. The diagnosis of intracranial tuberculoma should rest on a proper integration of data from clinical manifestations, cerebrospinal fluid analysis, and neuroimaging studies. (orig.).

    Full Text Available Evidence about distribution patterns of brain metastases with regard to breast cancer subtypes and its influence on the prognosis of patients is insufficient. Clinical data, cranial computed tomography (CT and magnetic resonance imaging (MRI scans of 300 breast cancer patients with brain metastases (BMs were collected retrospectively in four centers participating in the Brain Metastases in Breast Cancer Registry (BMBC in Germany. Patients with positive estrogen (ER, progesterone (PR, or human epidermal growth factor receptor 2 (HER2 statuses, had a significantly lower number of BMs at diagnosis. Concerning the treatment mode, HER2-positive patients treated with trastuzumab before the diagnosis of BMs showed a lower number of intracranial metastases (p < 0.001. Patients with a HER2-positive tumor-subtype developed cerebellar metastases more often compared with HER2-negative patients (59.8% vs. 44.5%, p = 0.021, whereas patients with triple-negative primary tumors had leptomeningeal disease more often (31.4% vs. 18.3%, p = 0.038. The localization of Brain metastases (BMs was associated with prognosis: patients with leptomeningeal disease had shorter survival compared with patients without signs of leptomeningeal disease (median survival 3 vs. 5 months, p = 0.025. A shorter survival could also be observed in the patients with metastases in the occipital lobe (median survival 3 vs. 5 months, p = 0.012. Our findings suggest a different tumor cell homing to different brain regions depending on subtype and treatment.

  11. Intracranial Atherosclerotic Disease

    Full Text Available Intracranial atherosclerotic disease (ICAD is the most common proximate mechanism of ischemic stroke worldwide. Approximately half of those affected are Asians. For diagnosis of ICAD, intra-arterial angiography is the gold standard to identify extent of stenosis. However, noninvasive techniques including transcranial ultrasound and MRA are now emerging as reliable modalities to exclude moderate to severe (50%–99% stenosis. Little is known about measures for primary prevention of the disease. In terms of secondary prevention of stroke due to intracranial atherosclerotic stenosis, aspirin continues to be the preferred antiplatelet agent although clopidogrel along with aspirin has shown promise in the acute phase. Among Asians, cilostazol has shown a favorable effect on symptomatic stenosis and is of benefit in terms of fewer bleeds. Moreover, aggressive risk factor management alone and in combination with dual antiplatelets been shown to be most effective in this group of patients. Interventional trials on intracranial atherosclerotic stenosis have so far only been carried out among Caucasians and have not yielded consistent results. Since the Asian population is known to be preferentially effected, focused trials need to be performed to establish treatment modalities that are most effective in this population.

    Wang, Yutang; Emeto, Theophilus I; Lee, James; Marshman, Laurence; Moran, Corey; Seto, Sai-wang; Golledge, Jonathan


    Subarachnoid hemorrhage secondary to rupture of an intracranial aneurysm is a highly lethal medical condition. Current management strategies for unruptured intracranial aneurysms involve radiological surveillance and neurosurgical or endovascular interventions. There is no pharmacological treatment available to decrease the risk of aneurysm rupture and subsequent subarachnoid hemorrhage. There is growing interest in the pathogenesis of intracranial aneurysm focused on the development of drug therapies to decrease the incidence of aneurysm rupture. The study of rodent models of intracranial aneurysms has the potential to improve our understanding of intracranial aneurysm development and progression. This review summarizes current mouse models of intact and ruptured intracranial aneurysms and discusses the relevance of these models to human intracranial aneurysms. The article also reviews the importance of these models in investigating the molecular mechanisms involved in the disease. Finally, potential pharmaceutical targets for intracranial aneurysm suggested by previous studies are discussed. Examples of potential drug targets include matrix metalloproteinases, stromal cell-derived factor-1, tumor necrosis factor-α, the renin-angiotensin system and the β-estrogen receptor. An agreed clear, precise and reproducible definition of what constitutes an aneurysm in the models would assist in their use to better understand the pathology of intracranial aneurysm and applying findings to patients.

    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE Intracranial pressure is total of pressure that is produced by brain, blood, and cerebrospinal fluid/CSF in the tight cranial space. As a respon to intracranial pressure increasing, compensation begin by movement of CSF from ventricle to cerebral subarachnoidal space, and increase the absorption of CSF. Increasing of ICP usually caused by increasing of brain volume (cerebral oedem, blood (intracranial bleeding, space occupying lesion, or CSF (hidrocephalus. Indication in ICP monitoring can be seen from : neurological criteria, abnormal CT-scan result when admission, normal CT-scan result, but had more two risk factors. According to the procedure that must be done, there are two methods in ICP monitoring: invasive ICP monitoring methodes and non-invasive measuring method. Increasing of ICP will decrease the compliance of brain, pulsation of artery more clearly, and the component of vein is lost. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

    Afshan B. Hameed


    Full Text Available A pregnant woman with a mechanical prosthetic mitral valve was anticoagulated with low-molecular-weight heparin in the first trimester followed by warfarin until 36 weeks' gestation. She was then switched to intravenous unfractionated heparin infusion to allow for regional anesthesia in anticipation of vaginal delivery. She developed severe headache on hospital day 2 that was refractory to pain medications. Cranial imaging demonstrated a large subdural hematoma with midline shift. She delivered a healthy baby girl by cesarean section. Eventually, symptoms and intracranial abnormalities resolved over time. In conclusion, subdural hematoma is a relatively rare complication that requires multidisciplinary management plan.

  17. Pediatric intracranial aneurysms. (United States)

    Tripathy, L N; Singh, S N


    The incidence of subarachnoid haemorrhage from intracranial aneurysms in the paediatric age group is extremely rare. Interestingly, occurrence of vasospasm has been reported to be less in comparison to the adults. Both coiling and clipping have been advocated in selected cases. Because of the thinness of the wall of the arteries, utmost care should be taken while handling these arteries during surgery. The overall results of surgery in children have been reported to be better than their adult counterparts. We present four such cases from our own experience. All these children were operated upon, where the solitary aneurysm in each case was clipped and all of them made a good recovery.

    Boyer, Matthew J; Ricardi, Umberto; Ball, David; Salama, Joseph K


    Pulmonary metastases are common in patients with cancer for which surgery is considered a standard approach in appropriately selected patients. A number of patients are not candidates for surgery due to a medical comorbidities or the extent of surgery required. For these patients, noninvasive or minimally invasive approaches to ablate pulmonary metastases are potential treatment strategies. This article summarizes the rationale and outcomes for non-surgical treatment approaches, including radiotherapy, radiofrequency and microwave ablation, for pulmonary metastases.

  1. Bilateral sphenoid wing metastases of prostate cancer presenting with extensive brain edema. (United States)

    Lindsberg, P J; Tatlisumak, T; Tienari, J; Brander, A


    A 76-year-old man insidiously developed diffuse neurological symptoms: cognitive decline, dysphagia, dysphasia and mental disturbance. Computed tomography of the cranium revealed widespread bilateral brain edema and symmetrical bilateral sphenoid wing hyperostosis. Adjacent to the hyperostosis that resembled skull base meningiomas, two separate parenchymatous temporal lobe lesions enhancing with contrast medium were observed. The patient had earlier been diagnosed to have prostatic carcinoma. Dexamethasone therapy resulted in discontinuation of the neurological symptoms. The diagnosis of metastasized adenocarcinoma of the prostate was confirmed histologically on autopsy after a sudden death from pneumonia. Intracranial metastases of prostate cancer may have a predilection site at the sphenoid wing, and can mimic a skull base meningioma. Intracranial spread of prostatic adenocarcinoma should be considered in elderly men as a treatable cause of gradual neurological deterioration, especially if cranial malignancy or hyperostosis is found.

    Brain metastases are most common in adults with lung cancer, predicting uniformly poor patient outcome, with a median survival of only months. Despite their frequency and severity, very little is known about tumorigenesis in brain metastases. We applied previously developed primary solid tumor-initiating cell models to the study of brain metastases from the lung to evaluate the presence of a cancer stem cell population. Patient-derived brain metastases (n = 20) and the NCI-H1915 cell line were cultured as stem-enriching tumorspheres. We used in vitro limiting-dilution and sphere-forming assays, as well as intracranial human-mouse xenograft models. To determine genes overexpressed in brain metastasis tumorspheres, we performed comparative transcriptome analysis. All statistical analyses were two-sided. Patient-derived brain metastasis tumorspheres had a mean sphere-forming capacity of 33 spheres/2000 cells (SD = 33.40) and median stem-cell frequency of 1/60 (range = 0-1/141), comparable to that of primary brain tumorspheres (P = .53 and P = .20, respectively). Brain metastases also expressed CD15 and CD133, markers suggestive of a stemlike population. Through intracranial xenotransplantation, brain metastasis tumorspheres were found to recapitulate the original patient tumor heterogeneity. We also identified several genes overexpressed in brain metastasis tumorspheres as statistically significant predictors of poor survival in primary lung cancer. For the first time, we demonstrate the presence of a stemlike population in brain metastases from the lung. We also show that NCI-H1915 tumorspheres could be useful in studying self-renewal and tumor initiation in brain metastases. Our candidate genes may be essential to metastatic stem cell populations, where pathway interference may be able to transform a uniformly fatal disease into a more localized and treatable one.

  3. Multiple intracranial lipoma

    Directory of Open Access Journals (Sweden)

    B P Venkatesh


    Full Text Available Intracranial lipomas are rare congenital, non-neoplastic lesions discovered incidentally on computerised tomography (CT or magnetic resonance imaging (MRI with an incidence rate of less than 0.1% of all intracranial tumours. Most lipomas are asymptomatic pericallosal lesions sometimes presenting with seizures or headache. Corpus callosum agenesis and defects of midline structures differentiation may be present. Callosal lipomas are of two types: Anterior bulky tubulonodular variety associated with forebrain and rostral callosal anomalies, and posterior ribbon-like curvilinear lipoma generally seen with a normal or near normal corpus callosum. Corpus callosal hypogenesis/agenesis is seen in up to 90% of anterior and 30% of posterior pericallosal lipomas. The association of corpus callosal lipoma with choroid plexus lipoma is variable with its reported incidence rate being 20-50%. A 50-year-old patient was referred to our department for CT scan of brain with history of recent onset of headache and one episode of seizure. We present the imaging findings in this rare case of callosal tubulonodular lipoma having prominent intralesional vessels and extensive calcification with a concomitant intraventricular lipoma in a patient with dysgenetic corpus callosum.

    To analyse the survival rate of a cohort of patients with intracranial metastases treated with radiosurgery, and to determine the factors that influence the results. Retrospective analysis performed on a cohort of 126 patients undergoing radiosurgery for brain metastases. Patients treated with surgery before or after radiosurgery were excluded. Survival is analysed based on clinical (age, sex, primary tumour), radiological (number, location and volume of lesions), and radiotherapy factors (treatment dose, holocraneal radiation). Univariate and multivariate analyses were performed to determine significant prognostic factors. A total of 225 brain metastases in 126 patients, with a mean age of 59.8±11.6years, were treated between February 2008 and April 2015. The mean survival was 8.2 months. The overall survival rates at 6months, 1year, and 2years were 60.3%, 31.5%, and 12.8%, respectively. Lung (59.5%) and breast (14.3) were the most common primary tumours, and the most common site for metastases was the cerebral hemisphere (77%) and the average volume was 10.35 cc (0.2-43.5). Significant survival factors were: age under 60 (P=.046), female (P80 (P=.001), SIR6 >5 (P=.031), and GPA ≥2.5 (P=.003). Radiosurgery is an appropriate technique for the treatment of brain metastases, and the main prognostic factors include being age under 65, female, breast cancer, and good scores on Karnofsky, SIR, and GPA scales.

    Full Text Available Medulloblastoma is the most common childhood malignant tumor of central nervous system, but it may also occur in adults. It presents high invasive growth with spreading of tumor cells into the leptomeningeal space along the neuroaxis early in the course of the disease. Extraneural metastases are rare but frequently lethal, occurring only in 1 to 5% of patients, and are related, in the most of cases, to the presence of ventriculoperitoneal shunt. Here we characterize the clinical profile of five cases of medulloblastoma with systemic spreading of tumor cells, also comparing them to cases already described in the literature.

    Sixteen patients with choroid secondary tumours were treated with irradiation consisting of 40-50 Gy in 3-5 weeks. There were 14 female patients with breast cancer, one male patient with prostatic cancer and one male patient with cancer of unknown origin. In four cases bilateral ocular metastases were seen. Ten out of 20 treated eyes showed complete response to treatment, seven out of 20 showed partial response and three out of 20 were not influenced by irradiation. Survival of patients, all having widespread metastatic disease, was 3-48 months (median 20 months). All patients responding to treatment showed increased quality of life.

    Full Text Available Abstract Background Umbilical metastases from a malignant neoplasm, also termed Sister Mary Joseph's nodule, are not commonly reported in the English literature, and they have usually been considered as a sign of a poor prognosis for the patient. The present article reports on the current view point on umbilical metastasis besides discussing the epidemiology, clinical presentation, pathophysiology and treatment. Method A search of Pubmed was carried out using the term 'umblic*' and 'metastases' or metastasis' revealed no references. Another search was made using the term "Sister Joseph's nodule" or sister Joseph nodule" that revealed 99 references. Of these there were 14 review articles, however when the search was limited to English language it yielded only 20 articles. Articles selected from these form the basis of this report along with cross references. Results The primary lesions usually arise from gastrointestinal or genitourinary tract malignancies and may be the presenting symptom or sign of a primary tumour in an unknown site. Conclusion A careful evaluation of all umbilical lesions, including an early biopsy if appropriate, is recommended. Recent studies suggest an aggressive surgical approach combined with chemotherapy for such patients may improve survival.

    Full Text Available Aims: Differentiating intracranial mass lesions on CT scan is challenging. The purpose of our study was to determine the perfusion parameters in various intracranial space-occupying lesions (ICSOL, differentiate benign and malignant lesions, and differentiate between grades of gliomas. Materials and Methods: We performed CT perfusion (CTP in 64 patients, with age ranging from 17 to 68 years, having space-occupying lesions in brain and calculated relative cerebral blood flow (rCBF and relative cerebral blood volume (rCBV. Results: We found significantly lower perfusion in low-grade gliomas as compared to high-grade tumors, lymphoma, and metastases. Similarly in infective lesions, TWT and abscesses showed significantly lower perfusion compared to TOT. In ring enhancing lesions, capsule of TWT showed significantly lower perfusion as compared to abscesses, TOT, and metastases. Conclusion: Thus, in conclusion, infective lesions can be differentiated from tumors like lymphomas, high-grade gliomas, or metastases based on perfusion parameters. The cut off value of rCBV 1.64 can be used to differentiate between low grade and high grade gliomas. However, depending only on perfusion parameters, differentiation between the tumors like lymphomas, high-grade gliomas, and metastases may not be possible.

    Directory of Open Access Journals (Sweden)

    Hanson Peter W


    Full Text Available Abstract Melanoma and renal cell carcinoma have a well-documented tendency to develop metastases to the brain. Treating these lesions has traditionally been problematic, because chemotherapy has difficulty crossing the blood brain barrier and whole brain radiation therapy (WBRT is a relatively ineffective treatment against these radioresistant tumor histologies. In recent years, stereotactic radiosurgery (SRS has emerged as an effective and minimally-invasive treatment modality for irradiating either single or multiple intracranial structures in one clinical treatment setting. For this reason, we conducted a review of modern literature analyzing the efficacy of SRS in the management of patients with melanoma and renal cell carcinoma brain metastases. In our analysis we found SRS to be a safe, effective and attractive treatment modality for managing radioresistant brain metastases and highlighted the need for randomized trials comparing WBRT alone vs. SRS alone vs. WBRT plus SRS in treating patients with radioresistant brain metastases.

    Central nervous system metastases have been reported in 15-25% of breast cancer patients, and the incidence is increasing. Moreover, the survival of these patients is generally poor, with reports of a 1-year survival rate of 20%. Therefore, a better knowledge about the determinants of brain metastasization is essential for the improvement of the clinical outcomes. Here, we summarize the current data about the metastatic cascade, ranging from the output of cancer cells from the primary tumour to their colonization in the brain, which involves the epithelial-mesenchymal transition, invasion of mammary tissue, intravasation into circulation, and homing into and extravasation towards the brain. The phenotypic change in malignant cells, and the importance of the microenvironment in the formation of brain metastases are also inspected. Finally, the importance of genetic and epigenetic changes, and the recently disclosed effects of microRNAs in brain metastasization of breast cancer are highlighted. Copyright © 2017 Elsevier B.V.

  19. Mammaglobin-A immunohistochemistry in primary central nervous system neoplasms and intracranial metastatic breast carcinoma. (United States)

    Cimino, Patrick J; Perrin, Richard J


    Metastases represent the most common type of intracranial neoplasm. In women, 30% of such tumors derive from breast carcinoma. In neurosurgical cases with ambiguous cellular morphology and/or limited biopsy material, immunohistochemistry (IHC) is often performed to distinguish metastases from primary central nervous system (CNS) neoplasms. IHC for mammaglobin-A (MGA), a protein expressed in a majority of breast carcinomas, is commonly applied in this setting, but its utility for distinguishing primary CNS neoplasms from metastatic breast carcinoma is unknown; the reactivity of MGA in primary and metastatic CNS neoplasms has never been described. Here, we describe the frequency and patterns of IHC reactivity for MGA in metastatic and primary CNS neoplasms from patients with well-documented histories of breast carcinoma. Following a published protocol previously applied to non-CNS neoplasms, MGA staining of moderate to strong intensity within 5% or more of a neoplasm was considered positive. On the basis of these criteria, 3 of 12 (25.0%) glioblastomas, 1 of 10 (10.0%) meningiomas, and 47 of 95 (49.5%) metastases were positive. Importantly, the cytoarchitectural staining characteristics among all 4 MGA-positive primary CNS neoplasms (cytoplasmic and nuclear) differed from those of the metastases (cytoplasmic and membranous). These findings suggest that MGA IHC staining intensity and distribution can distinguish metastases from primary CNS neoplasms (P=0.0086) in women with a history of breast carcinoma but also indicate that cytologic staining patterns must be interpreted for more accurate tumor classification.

    Douglas A Hardesty


    Full Text Available Brain metastases are the most common intracranial malignancy, accounting for significant morbidity and mortality in oncology patients. The current treatment paradigm for brain metastasis depends on the patient’s overall health status, the primary tumor pathology, and the number and location of brain lesions. Herein, we review the modern management options for these tumors, including surgical resection, radiotherapy, and chemotherapy. Recent operative advances, such as fluorescence, confocal microscopy, and brachytherapy, are highlighted. With an increased understanding of the pathophysiology of brain metastasis come increased future therapeutic options. Therapy targeted to specific tumor molecular pathways, such as those involved in blood-brain barrier transgression, cell-cell adhesion, and angiogenesis, are also reviewed. A personalized plan for each patient, based on molecular characterizations of the tumor that are used to better target radiotherapy and chemotherapy, is undoubtedly the future of brain metastasis treatment.

    Helder Picarelli


    Full Text Available Brain metastases (BM are one of the most common intracranial tumors and surgical treatment can improve both the functional outcomes and patient survival, particularly when systemic disease is controlled. Image-guided BM resection using intraoperative exams, such as intraoperative ultrasound (IOUS, can lead to better surgical results. METHODS: To evaluate the use of IOUS for BM resection, 20 consecutives patients were operated using IOUS to locate tumors, identify their anatomical relationships and surgical cavity after resection. Technical difficulties, complications, recurrence and survival rates were noted. RESULTS: IOUS proved effective for locating, determining borders and defining the anatomical relationships of BM, as well as to identify incomplete tumor resection. No complications related to IOUS were seen. CONCLUSION: IOUS is a practical supporting method for the resection of BM, but further studies comparing this method with other intraoperative exams are needed to evaluate its actual contribution and reliability.

    Full Text Available Spontaneous intracranial hypotension is an important cause of new daily persistent headaches in young and middle-aged individuals. The diagnosis is made based on low cerebrospinal fluid pressure with characteristic findings upon brain and spinal magnetic resonance imaging (MRI. We present the case of a 15-year-old boy with spontaneous intracranial hypotension. Although his brain MRI was normal, his lumbar spinal MRI showed clustering of the nerve roots characteristic of arachnoiditis. Radionuclide cisternography revealed an epidural leak, which was treated with an epidural blood patch. The patient reached a near-full recovery within 24 h, and the lumbar spinal MRI findings mimicking arachnoiditis disappeared.

    Aneurysmal bone cysts (ABCs) are benign, expansile, blood-filled, osteolytic lesions with internal septations that may be intraosseous or extraosseous. The cysts may cause local mass effect, and changes in the regional vascular supply necessitating intervention. A case of an intracranial, intradural ABC in a young male patient with progressively severe headaches is presented. This is only the third recorded intradural case, the majority of these rare lesions being extracranial and only a minute fraction intracranial. Copyright © 2015 Elsevier Inc. All rights reserved.

    RAF inhibitors are an effective therapy for patients with BRAF-mutant melanoma and brain metastasis. Efficacy data are derived from clinical studies enriched with physiologically fit patients; therefore, it is of interest to assess the real-world experience of vemurafenib in this population. Tumor-specific genetic variants that influence sensitivity to RAF kinase inhibitors also require investigation. Records of patients with BRAF-mutant melanoma and brain metastases who were treated with vemurafenib were reviewed. Clinical data were extracted to determine extracranial and intracranial objective response rates, progression-free survival (PFS), overall survival (OS), and safety. A bait-capture, next-generation sequencing assay was used to identify mutations in pretreatment tumors that could explain primary resistance to vemurafenib. Among patients with intracranial disease treated with vemurafenib, 27 were included in survival analyses and 22 patients were assessable for response. The extracranial and intracranial objective response rates were 71% and 50%, respectively. Discordant responses were observed between extracranial and intracranial metastatic sites in 4 of 19 evaluable patients. Median PFS was 4.1 months (95% confidence interval [CI]: 2.6-7.9); median intracranial PFS was 4.6 months (95% CI: 2.7-7.9), median OS was 7.5 months (95% CI: 4.3-not reached), with a 30.4% 1-year OS rate. Outcomes were influenced by performance status. Vemurafenib was tolerable, although radiation-induced dermatitis occurred in some patients who received whole-brain radiotherapy. Adequate samples for next-generation sequencing analysis were available for seven patients. Melanomas categorized as "poorly sensitive" (≥20% tumor growth, new lesions, or ≤50% shrinkage for brain metastases but has limited activity in patients with poor performance status. The safety and efficacy of concurrent radiotherapy and RAF inhibition requires careful clinical evaluation. Combination

  12. Impact of Triple-Negative Phenotype on Prognosis of Patients With Breast Cancer Brain Metastases

    Purpose: To elucidate survival times and identify potential prognostic factors in patients with triple-negative (TN) phenotype who harbored brain metastases arising from breast cancer and who underwent stereotactic radiosurgery (SRS). Methods and Materials: A total of 103 breast cancer patients with brain metastases were treated with SRS and then studied retrospectively. Twenty-four patients (23.3%) were TN. Survival times were estimated using the Kaplan-Meier method, with a log-rank test computing the survival time difference between groups. Univariate and multivariate analyses to predict potential prognostic factors were performed using a Cox proportional hazard regression model. Results: The presence of TN phenotype was associated with worse survival times, including overall survival after the diagnosis of primary breast cancer (43 months vs. 82 months), neurologic survival after the diagnosis of intracranial metastases, and radiosurgical survival after SRS, with median survival times being 13 months vs. 25 months and 6 months vs. 16 months, respectively (p < 0.002 in all three comparisons). On multivariate analysis, radiosurgical survival benefit was associated with non-TN status and lower recursive partitioning analysis class at the initial SRS. Conclusion: The TN phenotype represents a significant adverse prognostic factor with respect to overall survival, neurologic survival, and radiosurgical survival in breast cancer patients with intracranial metastasis. Recursive partitioning analysis class also served as an important and independent prognostic factor.

    Osawa, Shin-ichiro; Kumabe, Toshihiro; Saito, Ryuta; Sonoda, Yukihiko; Niizuma, Hidetaka; Watanabe, Mika; Tominaga, Teiji


    Three pediatric patients with infratentorial metastatic non-epithelial malignant brain tumors were successfully treated by radical surgical resection followed by aggressive radiochemotherapy. One patient with neuroblastoma and two with rhabdomyosarcoma were successfully treated by first line multimodal treatments, but developed infratentorial metastasis after several months of remission. All patients revealed intracranial metastases manifesting as rapidly progressing neurological symptoms caused by mass effect in the posterior fossa. Radical surgical resection was performed without morbidity. The patients were then treated by adjuvant radiochemotherapy with or without autologous peripheral blood stem cell transplantation, resulting in complete remission. Two patients developed extracranial recurrences 4 months after the treatments for intracranial metastases. One patient was treated by second high-dose chemotherapy with allogeneic cord blood transplantation, again resulting in complete remission. Another patient was treated by second chemotherapy and maintaining stable disease. The other patient maintained complete remission. All three patients were alive without neurological deficit for 8, 11, and 12 months after diagnosis of brain metastasis. Patients with infratentorial brain metastases of highly malignant pediatric non-epithelial tumors are in a severe clinical state, but still can have longer and useful lives with aggressive multimodal treatments combined with radical surgical resection.

    Full Text Available Benign intracranial hypotension, otherwise called as idiopathic intracranial hypotension is caused by CSF leaks due to disruption in spinal meninges. It is most commonly caused by disruption and leak at cervical and thoracic spine. Imaging is sometimes the most important key to the diagnosis of idiopathic intracranial hypotension, which helps in appropriate treatment of the patient. Here, we are presenting a case of benign intracranial hypotension associated with incidental parasagittal meningioma. The presence of benign intracranial hypotension was confirmed by taking MR myelogram.

  16. [Bone metastases treated with radiopharmaceuticals]. (United States)

    Giammarile, Francesco


    The administration of a radionuclide in unsealed source whose radiation will destroy cells that have selectively accumulated product is called radiometabolic therapy. The management of bone pain is a major problem, particularly in cases of breast or prostate where the presence of metastases can remain compatible with long-term survival of cancer patients. In this context, the radiometabolic therapy reduces the pain secondary to bone metastases, in association or not with analgesics. This technique is rarely prescribed as first-line. It can also be combined with external beam radiotherapy or chemotherapy, if clinical conditions permit (due to the increased risk of hematologic toxicity). In this setting, the currently used substances are Metastron® and Quadramet®. Recently, a new product, radium chloride (or Alpharadin®) has shown efficacy in bone metastases from prostate cancer, particularly in terms of bone pain palliation, but also of increased overall survival. In addition, this product has virtually no hematologic toxicity.

    Reinstein, Zachary Z; Pamarthy, Sahithi; Sagar, Vinay; Costa, Ricardo; Abdulkadir, Sarki A; Giles, Francis J; Carneiro, Benedito A


    Bone metastases are present in up to 70% of advanced prostate and breast cancers and occur at significant rates in a variety of other cancers. Bone metastases can be associated with significant morbidity. The establishment of bone metastasis activates several immunosuppressive mechanisms. Hence, understanding the tumor-bone microenvironment is crucial to inform the development of novel therapies. This review describes the current standard of care for patients with bone metastatic disease and novel treatment options targeting the microenvironment. Treatments reviewed include immunotherapies, cryoablation, and targeted therapies. Combinatorial treatment strategies including targeted therapies and immunotherapies show promise in pre-clinical and clinical studies to overcome the suppressive environment and improve treatment of bone metastases.

    Esthesioneuroblastoma (ENB) is an aggressive neuroectodermal malignancy in the upper nasal cavity with local infiltration and lymphatic or hematogenous metastasis. The purpose of this paper is to document three types of direct intracranial extensions by ENB using computed tomography (CT) and magnetic resonance imaging (MRI). Eleven patients with pathologically confirmed ENB were admitted in our hospital between December 2002 and December 2008. Their magnetic resonance (MR; n = 10) and CT (n = 8) images were retrospectively reviewed, and particular attention was paid to tumor location and extension, enhancement pattern, cervical lymph node metastasis, and Kadish stage. The majority of patients were male (8/11) with Kadish stage C tumor (10/11). Three types of direct intracranial extension by ENBs were put forward according to their MR and CT findings. The primary tumors were well-defined soft-tissue masses centered in the roof of the nasal cavity eroding into the paranasal sinuses (11/11), the contralateral nasal cavity (4/11), the cranial cavity (5/11), and the fossa orbitalis (3/11). The tumor parenchyma were hypointensity on T1-weighted images, heterogeneous hyperintensity on T2-weighted images, and isodensity or slight hyperdensity on CT images with scattered necroses (4/11) and marginal cysts(4/11). Their enhancements were significant and inhomogeneous. Cervical lymph nodes metastases were observed in four patients (4/11), but no pathologically proved distant metastasis was observed. Three types of direct intracranial extensions by ENB can be found on CT and MRI: cranio-orbital-nasal-communicating ENB, cranio-nasal-communicating ENB, and orbital-nasal-communicating ENB. (orig.)

    Full Text Available Aim: Several epidemiological studies have shown an inverse correlation between allergy and brain cancer. The purpose of this study was to compare the serum IgE levels between patients with gliomas and nonglial tumors and their possible prognostic role. Methods: A total of 84 patients with intracranial tumors were included in this study. At clinical presentation, estimation of serum IgE levels was assessed by nephelometry. Detailed information regarding the history of allergies was collected by interview. Results: Of the 84 cases, 42 were gliomas, 23 were meningiomas, 16 were metastases and 3 were primary central nervous system lymphomas. Patients with high-grade glioma had lower IgE levels than patients with low-grade glioma. Patients with glioma and meningioma had statistical significant lower serum IgE levels than patients with metastases. Patients with glioblastoma with serum IgE levels greater than 24 U/mL had a better survival. Conclusion: Patients with glioma and meningioma had lower IgE levels than patients with metastatic lesions. A prognostic role of serum IgE levels was found in glioblastoma. Further studies in larger patient series are required in order to verify our preliminary observations.

We briefly discuss aspects of this comparatively rare gastrointestinal malignancy.

  1. Brain metastases from colorectal cancer: characteristics and management. (United States)

    Mege, Diane; Sans, Arnaud; Ouaissi, Mehdi; Iannelli, Antonio; Sielezneff, Igor


    Brain metastases (BMs) are the most common intracranial neoplasms in adults, but they rarely arise from colorectal cancer (CRC). The objective of this study was to report an overview of the characteristics and current management of CRC BMs. A systematic review on CRC BMs was performed using Medline database from 1983 to 2015. The search was limited to studies published in English. Review articles, not relevant case report or studies or studies relating to animal and in vitro experiments were excluded. BMs occurred in 0.06-4% of patients with CRC. Most BMs were metachronous and were associated with lung (27-92%) and liver (12-80%) metastases. Treatment options depended on the number of BMs, the general conditions of the patient and the presence of other metastases. Most frequent treatment was whole-brain radiotherapy (WBRT) alone (36%), with median overall survival comprised between 2 and 9 months. Median overall survival was better after surgery alone (from 3 to 16.2 months), or combined with WBRT (from 7.6 to 14 months). After stereotactic radiosurgery alone, overall survival could reach 9.5 months. Many favourable prognostic factors were identified, such as high Karnofsky performance status, low recursive partitioning analysis classes, lack of extracranial disease, low number of BMs and possibility to perform surgical treatment. BMs from CRC are rare. In the presence of favourable prognostic factors, an aggressive management including surgical resection with or without WBRT or stereotactic radiosurgery can improve the overall survival. © 2017 Royal Australasian College of Surgeons.

    Purpose/Objectives: Radiation therapy (RT) is the principal modality in the treatment of patients with brain metastases (BM). However, given the activity of EGFR tyrosine kinase inhibitors in the central nervous system, it is uncertain whether upfront brain RT is necessary for patients with EGFR-mutant lung adenocarcinoma with BM. Methods and Materials: Patients with EGFR-mutant lung adenocarcinoma and newly diagnosed BM were identified. Results: 222 patients were identified. Exclusion criteria included prior erlotinib use, presence of a de novo erlotinib resistance mutation, or incomplete data. Of the remaining 110 patients, 63 were treated with erlotinib, 32 with whole brain RT (WBRT), and 15 with stereotactic radiosurgery (SRS). The median overall survival (OS) for the whole cohort was 33 months. There was no significant difference in OS between the WBRT and erlotinib groups (median, 35 vs 26 months; P=.62), whereas patients treated with SRS had a longer OS than did those in the erlotinib group (median, 64 months; P=.004). The median time to intracranial progression was 17 months. There was a longer time to intracranial progression in patients who received WBRT than in those who received erlotinib upfront (median, 24 vs 16 months, P=.04). Patients in the erlotinib or SRS group were more likely to experience intracranial failure as a component of first failure, whereas WBRT patients were more likely to experience failure outside the brain (P=.004). Conclusions: The survival of patients with EGFR-mutant adenocarcinoma with BM is notably long, whether they receive upfront erlotinib or brain RT. We observed longer intracranial control with WBRT, even though the WBRT patients had a higher burden of intracranial disease. Despite the equivalent survival between the WBRT and erlotinib group, this study underscores the role of WBRT in producing durable intracranial control in comparison with a targeted biologic agent with known central nervous system activity.

  3. Whole brain radiotherapy after local treatment of brain metastases in melanoma patients - a randomised phase III trial

    Directory of Open Access Journals (Sweden)

    Forder Peta M


    Full Text Available Abstract Background Cerebral metastases are a common cause of death in patients with melanoma. Systemic drug treatment of these metastases is rarely effective, and where possible surgical resection and/or stereotactic radiosurgery (SRS are the preferred treatment options. Treatment with adjuvant whole brain radiotherapy (WBRT following neurosurgery and/or SRS is controversial. Proponents of WBRT report prolongation of intracranial control with reduced neurological events and better palliation. Opponents state melanoma is radioresistant; that WBRT yields no survival benefit and may impair neurocognitive function. These opinions are based largely on studies in other tumour types in which assessment of neurocognitive function has been incomplete. Methods/Design This trial is an international, prospective multi-centre, open-label, phase III randomised controlled trial comparing WBRT to observation following local treatment of intracranial melanoma metastases with surgery and/or SRS. Patients aged 18 years or older with 1-3 brain metastases excised and/or stereotactically irradiated and an ECOG status of 0-2 are eligible. Patients with leptomeningeal disease, or who have had previous WBRT or localised treatment for brain metastases are ineligible. WBRT prescription is at least 30 Gy in 10 fractions commenced within 8 weeks of surgery and/or SRS. Randomisation is stratified by the number of cerebral metastases, presence or absence of extracranial disease, treatment centre, sex, radiotherapy dose and patient age. The primary endpoint is the proportion of patients with distant intracranial failure as determined by MRI assessment at 12 months. Secondary end points include: survival, quality of life, performance status and neurocognitive function. Discussion Accrual to previous trials for patients with brain metastases has been difficult, mainly due to referral bias for or against WBRT. This trial should provide the evidence that is currently lacking in

    Kim In-Young


    Full Text Available Abstract Background Transitional cell carcinoma (TCC of the female urethra is a rare urological malignancy, and intracranial metastasis of this cancer has not yet been reported in the literature. This review is intended to present a case of multiple intracranial metastasis in a female patient with a remote history of primary urethral TCC. Case Presentation A 49-year-old woman, presented with a prolapsed mass in urethral orifice that was diagnosed as primary urethral TCC with distant lung and multiple bone metastases. The patient subsequently underwent chemotherapy under various regimens. A year later, the patient developed headache and vomiting which as was found to be due to multiple intracranial metastasis. The patient underwent surgical resection of the largest lesion located on the cerebellum, and consecutively gamma knife radiosurgery was performed for other small-sized lesions. Pathological examination of the resected mass revealed a metastatic carcinoma from a known urethral TCC. Serial work-up of systemic metastasis revealed concomitant aggravation of lung, spleen, and liver metastasis. The patient died of lung complication 2 months after the diagnosis of brain metastasis. Conclusion To the best of our knowledge, this is the first reported case of cerebral metastasis from primary urethral TCC, with pathological confirmation. As shown in intracranial metastasis of other urinary tract carcinoma, this case occurred in the setting of uncontrolled systemic disease and led to dismal prognosis in spite of aggressive interventional modalities.

The prognosis of resectable colorectal liver metastases (CRLM was improved in the recent years with the consideration of chemotherapy and surgical resection as part of the multidisciplinary management of the disease; the current 5-year survival rates after resection of liver metastases are 25% to 40%. Resectable synchronous or metachronous liver metastases should be treated with perioperative chemotherapy based on three months of FOLFOX4 (5-fluorouracil [5FU], folinic acid [LV], and oxaliplatin chemotherapy before surgery and three months after surgery. In the case of primary surgery, pseudo-adjuvant chemotherapy for 6 months, based on 5FU/LV, FOLFOX4, XELOX (capecitabine and oxaliplatin or FOLFIRI (5FU/LV and irinotecan, should be indicated. In potentially resectable disease, primary chemotherapy based on more intensive regimens such as FOLFIRINOX (5FU/LV, irinotecan and oxaliplatin should be considered to enhance the chance of cure. The palliative chemotherapy based on FOLFIRI, or FOLFOX4/XELOX with or without targeted therapies, is the mainstay treatment of unresectable disease. This review would provide additional insight into the problem of optimal integration of chemotherapy and surgery in the management of CRLM.

  7. Melanoma brain metastases: an unmet challenge in the era of active therapy. (United States)

    Gorantla, Vikram; Kirkwood, John M; Tawbi, Hussein A


    Metastatic disease to the brain is a frequent manifestation of melanoma and is associated with significant morbidity and mortality and poor prognosis. Surgery and stereotactic radiosurgery provide local control but less frequently affect the overall outcome of melanoma brain metastases (MBM). The role of systemic therapies for active brain lesions has been largely underinvestigated, and patients with active brain lesions are excluded from the vast majority of clinical trials. The advent of active systemic therapy has revolutionized the care of melanoma patients, but this benefit has not been systematically translated into intracranial activity. In this article, we review the biology and clinical outcomes of patients with MBM, and the evidence supporting the use of radiation, surgery, and systemic therapy in MBM. Prospective studies that included patients with active MBM have shown clinical intracranial activity that parallels systemic activity and support the inclusion of patients with active MBM in clinical trials involving novel agents and combination therapies.

  8. Intracranial Metastatic Neuroblastoma Treated with Gamma Knife Stereotactic Radiosurgery: Report of Two Novel Cases

    Directory of Open Access Journals (Sweden)

    Nathan C. Rowland


    Full Text Available Intracranial metastasis of neuroblastoma (IMN is associated with poor survival. No curative therapy for the treatment of IMN currently exists. Unfractionated radiotherapy may be beneficial in the treatment of IMN given the known radiosensitivity of neuroblastoma as well as its proclivity to metastasize as discrete lesions. We present two patients with IMN treated with Gamma Knife stereotactic radiosurgery (SRS. Single-fraction radiotherapy yielded temporary reduction of tumor burden and stability of disease in both patients. SRS may be a useful palliative tool in the treatment of IMN and expands the overall treatment options for this disease.

    Intracranial metastases are a rare manifestation of prostate carcinoma and the dura mater is the most affected site. We report a series of six patients with dural prostate metastases (DPM) and perform a systematic review of the current literature in order to depict imaging trademarks of this condition. This review points to a magnetic resonance imaging (MRI) pattern of meningeal involvement characterized by a diffuse smooth thickening, nodular appearance or dural-based masses. We also demonstrate an osteoblastic pattern of lesions, particularly in sphenoid wing, by computed tomography (CT) scans. We suggest that these imaging findings may support an elevated index of suspicion of DPM in elderly men, including those patients without urologic symptoms.

  10. Risk factors for leptomeningeal carcinomatosis in patients with brain metastases who have previously undergone stereotactic radiosurgery. (United States)

    Huang, Andrew J; Huang, Karen E; Page, Brandi R; Ayala-Peacock, Diandra N; Lucas, John T; Lesser, Glenn J; Laxton, Adrian W; Tatter, Stephen B; Chan, Michael D


    Our objective was to explore the hypothesis that the risk of leptomeningeal dissemination (LMD) in patients who underwent stereotactic radiosurgery (SRS) for brain metastases is influenced by the site of the primary cancer, the addition of whole brain radiation therapy (WBRT), surgical resection, and control over their systemic disease. We conducted a retrospective cohort analysis of 805 patients who were treated with SRS for brain metastases between 1999 and 2012 at the Wake Forest Baptist Medical Center, and excluded all patients with evidence of LMD before SRS. The primary outcome was LMD. Forty-nine of 795 patients developed LMD with a cumulative incidence of 6.2% (95% Confidence Interval (CI), 4.7-8.0). Median time from SRS to LMD was 7.4 months (Interquartile Range (IQR), 3.3-15.4). A colorectal primary site (Hazard Ratio (HR), 4.5; 95% CI 2.5-8.0; p LMD. There was no evidence that surgical resection before SRS altered the risk of LMD (HR, 1.1; 95 % CI 0.6-2.0, p = 0.78). In patients who underwent SRS for brain metastases, a colorectal or breast primary site, distant brain failure, younger age, and an increased number of intracranial metastases were independently associated with LMD. Given its relative rarity as an outcome, multi-institutional prospective studies will likely be necessary to validate and quantify these relationships.

  11. The minor symptoms of increased intracranial pressure: 101 patients with benign intracranial hypertension. (United States)

    Round, R; Keane, J R


    Of 101 patients with benign intracranial hypertension not related to vasculitis, neck stiffness occurred in 31, tinnitus in 27, distal extremity paresthesias in 22, joint pains in 13, low back pain in 5, and gait "ataxia" in 4. Symptoms resolved promptly upon lowering the intracranial pressure by lumbar puncture, and were probably directly caused by intracranial hypertension. Awareness of these "minor" symptoms of increased intracranial pressure can facilitate diagnosis and management.

  12. Local control after stereotactic radiosurgery for brain metastases in patients with melanoma with and without BRAF mutation and treatment. (United States)

    Ly, David; Bagshaw, Hilary P; Anker, Christopher J; Tward, Jonathan D; Grossmann, Kenneth F; Jensen, Randy L; Shrieve, Dennis C


    BRAF inhibitors improve progression-free and overall survival in patients with metastatic melanoma. Brain metastases are common, and stereotactic radiosurgery (SRS) has been used, resulting in excellent local control. Because BRAF inhibitors are associated with intracranial responses, the authors hypothesized that BRAF inhibitors would improve local control in patients with melanoma who are receiving SRS for brain metastases. The authors retrospectively identified patients with metastatic melanoma who had been tested for BRAF mutation and treated with SRS for brain metastases. Patients with previous resection, multiple brain metastases, or multiple courses of SRS were eligible. SRS was delivered in a single fraction to a median dose of 2000 cGy. Patients with a BRAF mutation were treated with a BRAF inhibitor on the basis of physician preference. The authors identified 52 patients who were treated in 82 treatment sessions for 185 brain metastases and 13 tumor beds. At a median follow-up of 10.5 months, the 1-year local control rate was 69.2%. At 1 year, the local control rate for brain metastases in patients with BRAF mutation with BRAF treatment was 85.0%, and the local control rate for brain metastases in those without BRAF treatment was 51.5% (p = 0.0077). The rates of distant brain failure, freedom from whole-brain radiation, and overall survival were not different on the basis of BRAF mutation status or inhibitor therapy. The number of new intratumoral hemorrhages after SRS was increased significantly in patients with BRAF treatment. Treatment with BRAF inhibitors was associated with improved local control after SRS in patients with melanoma and brain metastases. An increased number of intratumoral hemorrhages was associated with BRAF inhibitor therapy.

    Background Echinococcosis is still endemic in many countries, including China, where it is especially prevalent in the northwest. The aim of this study was to enrich the international literature about the treatment of intracranial hydatid cysts.Methods We retrospectively reviewed the clinical features, radiological manifestations, and surgical outcome of 97 patients with intracranial hydatid cysts, who received surgical treatment at the Neurosurgical Department of First Affiliated Hospital of Xinjiang Medical University from 1985 to 2010 and followed up the patient via sending a questionnaire or telephone contact. Clinical outcome was evaluated using the Karnofsky Performance Scale Index.Results Headache and vomiting were the most common initial symptoms in our patients. Neurological deficits caused by the mass effect of the cysts were seen in 82 cases. On the X-ray, significant bone erosion was seen in only two cases with epidural hydatid cysts. Round-shaped and thin-walled homogeneous low-density cystic lesions without surrounding edema and enhancement were the main findings on computerized tomography (CT) in 95 patients with intraparenchymal hydatid cysts, while two cases with epidural hydatid cysts presented as a heterodensity lesions. On magnetic resonance imaging (MRI), hydatid cyst presented as a round-shaped low signal lesion in T1-weighted images and high signal lesion in T2-weighted images, without enhancement after contrast media injection, while the two cases with epidural cysts presented as mixed signal masses. Surgical removal of cyst was performed in all cases. Total removal was achieved in 93 cases without rupturing the cyst wall. Only two cysts ruptured during the dissection, resulting in two surgery-related mortalities. There was no other additional neurological deficit caused directly by surgery. In 97.2% of the patients, the Karnofsky Performance Scale score was 80 to 90 at the last follow-up.Conclusions Intracranial hydatid cyst is still a

    Infectious intracranial aneurysms are rare vascular lesions that classically occur in patients with infective endocarditis. We present a 49-year-old man with altered mental status and headache with rapid growth and rupture of an infectious intracranial aneurysm with catastrophic intracranial hemorrhage, and review issues related to open neurosurgical and endovascular interventions.

  15. Metastasizing Esthesioneuroblastoma in a Dog. (United States)

    Siudak, K; Klingler, M; Schmidt, M J; Herden, C


    A 7-year-old Afghan hound presented with a history of disorientation, loss of vision, and seizures. Magnetic resonance imaging helped identify a mass at the level of the main olfactory bulb that compressed and displaced adjacent tissues in the cribriform plate into the nasal cavity and nasopharynx. Bony structures were osteolytic. After removing almost 80% of the mass, the tumor recurred a few months later. Due to severe respiratory distress and subsequent to an ultrasound diagnosis of a liver tumor, the dog was euthanized. In addition to the nasal mass, a single nodule in the liver and multiple nodules in the lung were present. All masses had similar cell morphology and were diagnosed as metastasizing esthesioneuroblastoma. The neoplastic cells expressed neuron-specific enolase and chromogranin A, and a few cells within the nasal mass were positive for cytokeratin. This is the first description of a canine esthesioneuroblastoma with distant metastases.

    Brain metastases from colorectal cancer are rare. The prognosis for patients with even a single resectable brain metastasis is poor. A case of surgically treated cerebral metastasis from a rectal carcinoma is reported. The brain tumour was radically resected. However, cerebral, as well...... as extracerebral, disease recurred 12 months after diagnosis. Surgical removal of colorectal metastatic brain lesions in selected cases results in a longer survival time....

    The aim of this study is to present 2 rare cases of cutaneous metastases originated from adenocarcinoma of the gastro-esophageal junction, thus, underline the need for early diagnosis and possible treatment of suspicious skin lesions among patients with esophageal malignancy. Metastatic cancer to the skin originated from internal malignancies, mostly lung cancer, breast cancer, and colorectal cancer, constitute 0.5 to 9% of all metastatic cancers.5,8,15 Skin metastases, mainly from squamous cell carcinomas of the esophagus, are rarely reported. Cutaneous metastasis is a finding indicating progressiveness of the disease.17 More precisely, median survival is estimated approximately 4.7 months.2,14 This study is a retrospective review of 2 cases of patients with adenocarcinoma of the esophagus and a review of the literature. Two patients aged 60 and 32 years old, respectively, underwent esophagectomy. Both pathologic reports disclosed adenocarcinoma of the gastro-esophageal junction staged T3 N2 M0 (stage IIIB). During follow-up time, the 2 patients were diagnosed with cutaneous metastases originated from the primary esophageal tumor 11 and 4 months after surgery, respectively. The first patient is alive 37 months after diagnosis, while the second one died 16 months after surgery. Cutaneous metastasis caused by esophageal adenocarcinoma is possible. Therefore, follow-up of patients who were diagnosed with esophageal malignancy and underwent esophagectomy is mandatory in order to reveal early surgical stages. PMID:25785344

  18. Molecular insights into melanoma brain metastases. (United States)

    Westphal, Dana; Glitza Oliva, Isabella C; Niessner, Heike


    Substantial proportions of patients with metastatic melanoma develop brain metastases during the course of their disease, often resulting in significant morbidity and death. Despite recent advances with BRAF/MEK and immune-checkpoint inhibitors in the treatment of patients who have melanoma with extracerebral metastases, patients who have melanoma brain metastases still have poor overall survival, highlighting the need for further therapy options. A deeper understanding of the molecular pathways involved in the development of melanoma brain metastases is required to develop more brain-specific therapies. Here, the authors summarize the currently known preclinical data and describe steps involved in the development of melanoma brain metastases. Only by knowing the molecular background is it possible to design new therapeutic agents that can be used to improve the outcome of patients with melanoma brain metastases.

  19. Multifocal fibrosclerosis with intracranial pachymeningitis. (United States)

    Kitano, A; Shimomura, T; Okada, A; Takahashi, K


    A 29-year-old woman with a 4-year history of multifocal fibrosclerosis showed unique neurologic complications. Episcleritis, orbital pseudotumor, and eosinophilic phlegmon preceded intracranial inflammatory pachymeningitis. The pachymeningitis was associated with disturbance of the visual field, incomplete Gerstmann's syndrome, and pseudotumor cerebri. T2-weighted magnetic resonance images revealed a high signal intensity lesion in the left temporal and occipital lobes, and gadolinium-enhanced T1-weighted images revealed the enhancement of the thickened left tentorial leaf. The laboratory data suggested that the etiology might be autoimmunological. The disease and MRI abnormalities improved following administration of corticosteroids.

    Intracranial alveolar echinococcosis is uncommon. We report a patient with right frontal lobe and palpebral lesions secondary to a primary hepatic focus with secondary lesion in the lung. The intracranial and palpebral cystic masses were totally removed and both proved to be alveolar hydatid cysts. An unusual feature in this case is CT and MRI demonstration of dural and bony extension. (orig.)

  5. Intracranial arteriopathy in tuberous sclerosis complex. (United States)

    Boronat, Susana; Shaaya, Elias A; Auladell, Maria; Thiele, Elizabeth A; Caruso, Paul


    Arterial aneurysms, mostly aortic and intracranial, have been occasionally reported in patients with tuberous sclerosis complex. Brain magnetic resonance imaging reports of 404 patients with definite and 16 patients with either probable or possible tuberous sclerosis complex were revised for intracranial aneurysms. Among these patients, brain images of 220 patients with definite and 16 with probable or possible tuberous sclerosis complex were reviewed. Intracranial aneurysms were reported in 3 of 404 patients with a definite diagnosis (0.74%) (general population: 0.35%), including 2 children. A fourth intracranial aneurysm was found in a patient with probable tuberous sclerosis complex, who did not have tubers or subependymal nodules but had clinical manifestations related to neural crest derivatives, including lymphangioleiomyomatosis and extrarenal angiomyolipomas. The authors hypothesize that neural crest dysfunction can have a major role in intracranial arteriopathy in tuberous sclerosis complex, as smooth muscle cells in the forebrain vessels are of neural crest origin.

    CT is a valuable method in determining number, location and extent of lesions, although a definite diagnosis is often not possible on CT. In intracranial tuberculosis, CT was helpful in the diagnosis, assessing the degree of hydrocephalus and evaluating the effectiveness of antituberculous therapy. Twenty-one cases of clinically proven intracranial tuberculosis were studied by CT in our hospital during last 3 years. Of them, eighteen cases were tuberculous meningitis and the rests were tuberculoma. The results were as follows: 1. Tuberculous meningitis presented the following three patterns of CT findings according to its disease process. a. In early stage of the disease, suspicious multiple isodense small nodules in the cerebral and cerebellar hemispheres showed dense enhancement in postcontrast scan representing miliary tubercles. b. In later stage of the disease, precontrast scan showed partial or total obliteration of the basal and sylvian cisterns with mild dilatation of ventricular system. Postcontrast scan showed dense enhancement of basal and sylvian cisterns. This type of finding was the most common in our series. c. Moderate to marked dilatation of ventricle with or without a cluster of calcifications in suprsella area on precontrast scan was seen in far later stage of as a sequellae of the disease. No enhancement was noted in postcontrast study. 2. Tuberculoma showed an isodense or slightly hyperdense area in the cerebral or cerebellar hemisphere with associated minimal edema in precontrast study. Postcontrast scan showed a small ring enhancement with central lucent area.

    Stereotactic radiosurgery for intracranial meningiomas was attempted using a 201-source cobalt gamma knife. Forty patients bearing 42 tumors were involved in this study. Their ages ranged from 30 to 91 years, with an average of 55.1 years. The most frequent sites of origin were the parasellar and petroclival regions. The mean tumor diameter was 27.2 mm and the marginal tumor dose of radiosurgery ranged from 10 to 20 Gy, depending on tumor location and size. Serial imaging studies with MRI were obtained in all 40 cases, in which minor tumor shrinkage was demonstrated in 7.9%, 40.0% and 53.3% at 6, 12 and 18 months after radiosurgery respectively. Only two tumors became enlarged after the treatment. Obvious low signal intensity on MRI, indicating central tumor necrosis, was found in 32% at 12 months and 40% at 18 months. Four large tumors over 40 mm in mean diameter were treated by staged radiosurgery with intervals of 1.5 to 7 months. A similar good response was able to be obtained in all 4 cases, even though they were treated with a marginal dose less than 12 Gy. Symptomatic edema occurred in 5 cases (12.5%) within 12 months and required corticosteroid therapy and hyperosmotic diuresis. In conclusion stereotactic radiosurgery has proved to be an effective and relatively safe method for the treatment of intracranial meningiomas. (author).

  8. Desmopressin Acetate in Intracranial Haemorrhage

    Thomas Kapapa


    Full Text Available Introduction. The secondary increase in the size of intracranial haematomas as a result of spontaneous haemorrhage or trauma is of particular relevance in the event of prior intake of platelet aggregation inhibitors. We describe the effect of desmopressin acetate as a means of temporarily stabilising the platelet function. Patients and Methods. The platelet function was analysed in 10 patients who had received single (N=4 or multiple (N=6 doses of acetylsalicylic acid and 3 patients (control group who had not taken acetylsalicylic acid. All subjects had suffered intracranial haemorrhage. Analysis was performed before, half an hour and three hours after administration of desmopressin acetate. Statistical analysis was performed by applying a level of significance of P≤0.05. Results. (1 Platelet function returned to normal 30 minutes after administration of desmopressin acetate. (2 The platelet function worsened again after three hours. (3 There were no complications related to electrolytes or fluid balance. Conclusion. Desmopressin acetate can stabilise the platelet function in neurosurgical patients who have received acetylsalicylic acid prior to surgery without causing transfusion-related side effects or a loss of time. The effect is, however, limited and influenced by the frequency of drug intake. Further controls are needed in neurosurgical patients.

  9. Prescription dose and fractionation predict improved survival after stereotactic radiotherapy for brainstem metastases

    Leeman Jonathan E


    Full Text Available Abstract Background Brainstem metastases represent an uncommon clinical presentation that is associated with a poor prognosis. Treatment options are limited given the unacceptable risks associated with surgical resection in this location. However, without local control, symptoms including progressive cranial nerve dysfunction are frequently observed. The objective of this study was to determine the outcomes associated with linear accelerator-based stereotactic radiotherapy or radiosurgery (SRT/SRS of brainstem metastases. Methods We retrospectively reviewed 38 tumors in 36 patients treated with SRT/SRS between February 2003 and December 2011. Treatment was delivered with the Cyberknife™ or Trilogy™ radiosurgical systems. The median age of patients was 62 (range: 28–89. Primary pathologies included 14 lung, 7 breast, 4 colon and 11 others. Sixteen patients (44% had received whole brain radiation therapy (WBRT prior to SRT/SRS; ten had received prior SRT/SRS at a different site (28%. The median tumor volume was 0.94 cm3 (range: 0.01-4.2 with a median prescription dose of 17 Gy (range: 12–24 delivered in 1–5 fractions. Results Median follow-up for the cohort was 3.2 months (range: 0.4-20.6. Nineteen patients (52% had an MRI follow-up available for review. Of these, one patient experienced local failure corresponding to an actuarial 6-month local control of 93%. Fifteen of the patients with available follow-up imaging (79% experienced intracranial failure outside of the treatment volume. The median time to distant intracranial failure was 2.1 months. Six of the 15 patients with distant intracranial failure (40% had received previous WBRT. The actuarial overall survival rates at 6- and 12-months were 27% and 8%, respectively. Predictors of survival included Graded Prognostic Assessment (GPA score, greater number of treatment fractions, and higher prescription dose. Three patients experienced acute treatment-related toxicity consisting of

  10. Hyperaldosteronism associated with liver metastases. (United States)

    Pandya, K J; Whitehead, R; Crowley, J; Citrin, D L


    Plasma aldosterone levels were measured in 50 patients with confirmed liver metastases from various histologically proved primary tumors. None of these patients had electrolyte abnormalities or history of benign liver disease, congestive heart failure, hypertension, or renal disease. Patients with edema, ascites, or both had significantly greater elevation of plasma aldosterone levels compared to nonedematous patients; these patients also demonstrated a substantial degree of hepatic dysfunction as evidenced by lower serum albumin levels and higher bilirubin and alkaline phosphatase levels. This study provides a rational basis for the use of the specific aldosterone inhibitor spironolactone in the treatment of patients with advanced metastatic liver disease and edematous states.

  11. Testicular Metastases From Prostate Carcinoma

    Directory of Open Access Journals (Sweden)

    Harrina Erlianti Rahardjo


    Full Text Available Metastasis of prostate carcinoma to the testis is seldom reported. The tumour may spread from the prostatic urethra by retrograde venous extension, arterial embolism or through direct invasion into the lymphatics and lumen of the vas deferens. Clinical manifestations of secondary testicular tumours from the prostate are most often unsuspected clinically and are instead detected incidentally during orchidectomy. Less frequently, a palpable mass is detected, which may be confused with a primary testicular neoplasm. We report a case of a 66-year-old patient with adenocarcinoma of the prostate, and a left testicular tumour that was diagnosed as metastases from prostate carcinoma after radical orchidectomy.

  12. The incidence of radiation necrosis following stereotactic radiotherapy for melanoma brain metastases: the potential impact of immunotherapy. (United States)

    Kaidar-Person, Orit; Zagar, Timothy M; Deal, Allison; Moschos, Stergios J; Ewend, Matthew G; Sasaki-Adams, Deanna; Lee, Carrie B; Collichio, Frances A; Fried, David; Marks, Lawrence B; Chera, Bhishamjit S


    Stereotactic radiotherapy (SRT) is the standard treatment for patients with limited number of brain metastases. In the past few years, newer immunotherapies (immune checkpoint inhibitors) have been proven to prolong survival in patients with metastatic melanoma. The safety of the combination of SRT and immunotherapy for brain metastases is unknown. We retrospectively identified patients with melanoma brain metastases treated with SRT between 2007 and 2015. Patients who did not have at least 3 months of follow-up with imaging after SRT were excluded from the analysis. Outcomes were compared between patients who were treated with or without immunotherapy. A total of 58 patients were included; of these, 29 were treated with SRT and immunotherapy. MAPK inhibitors (BRAF, MEK inhibitors) were used more often in the immunotherapy group (nine vs. two patients). There was a higher incidence of intracranial complications in patients treated with immunotherapy and SRT. Eight patients had radiation necrosis; all occurred in patients who were treated with immunotherapy. Nine patients had hemorrhage, of which seven occurred in patients who were treated with immunotherapy (P=0.08). However, patients treated with immunotherapy and SRT had a significant overall survival advantage compared with SRT without immunotherapy (15 vs. 6 months, P=0.0013). Patients treated with SRT and immunotherapy have a higher incidence/risk of intracranial complications, but a longer overall survival.

    石浩军; 孔祥泉; 徐海波; 徐丽莹; 刘定西


    Summary: The MRI appearances of 7 adult patients with pathologically proven intracranial primitive neuroectodermal tumors (PNET) were retrospectively analyzed. The MRI features were compared with findings in pathology and surgery. In this group, the tumor masses were most commonly found in the semisphere of cerebrum and in the vermis of cerebellum. They were relatively large and 4 were in lobulated shape. All of them had well-defined margins. MR images showed the tumors to be mildly or obviously hypointense on Ti-weighted images and hyperintense on T2-weighted images. Most masses had heterogeneous appearances with some cystic and necrotic areas. Intratumoral haemorrhage and focal calcification were occasionally seen. Mostly, there was no or only mild surrounding edema. Marked inhomogeneous contrast enhancement on MRI was seen in 6 cases except one. Two patients with multiple intracranial metastases were revealed on MR images. In this series, there was good correlation between MRI features and findings in pathology and surgery.These results showed that certain MRI features might suggest the diagnosis of intracranial PNET in adults. MRI is an effective technique to detect these tumors and is helpful to treatment planning and follow-up.

    Objective: To study the mechanism, clinical characteristics, therapy regimens, and survival of cervical carcinoma metastases to the brain. Methods: We retrospectively analyzed 11 patients with brain metastases from cervical carcinoma. Results: Two cases were at stage lb, two at IIa, and seven at IIIb, respectively. Histologically, they were squamous cell carcinoma (6 cases), adeno-squamous carcinoma (2 cases), small cell carcinoma (2 cases), or adenocarcinoma (1 cases), poorly differentiated. Eight were accompanied with lung, liver, and bone metastases disease and three had no any other systemic metastases at the time of the brain metastases diagnosis. Two had controlled, and other nine were uncontrolled or progressive primary disease. The median interval from the diagnosis of the primary carcinoma to the detection of brain lesion was 14.6 months. Headache was the most common symptom of brain metastases. Eight of 11 patients developed multiple lesions and other 3 cases had a solitary lesion in brain. The patients were treated by combination of surgery and whole brain radiation therapy (WBRT) (3 cases), stereotactic radiosurgery (SRS) (3 cases), or WBRT (5 cases). The patients had a median survival of 6.6 months. Conclusion: Brain metastases are not always a late complication of cervical carcinoma. The development of the metastases is related to pathological type, poorly differentiation, and advanced stage. Surgery and SRS arc the appropriate therapy regimen for these patients.

  16. Cerebral venous etiology of intracranial hypertension and differentiation from idiopathic intracranial hypertension

    Directory of Open Access Journals (Sweden)

    Stefan Mircea Iencean


    Full Text Available This study presents the characteristics that distinguish between idiopathic intracranial hypertension (ICH and ICH caused by intracranial vascular damage. Twenty-one patients with ICH were included in this study. The analysis of the symptomatology correlated with the values of intracranial pressure, and the imaging findings revealed significant differences between these two types of ICH. ICH caused by intracranial venous vascular damage is named vascular ICH. Vascular ICH has a known etiology, such as cerebral vascular illness, and a relatively rapid increase in intracranial pressure of approximately 21 cmH2O and imaging findings show characteristic images of thrombosis or stenosis of the intracranial venous system, while all brain images (computed tomography, magnetic resonance imaging, angio-magnetic resonance imaging are normal in idiopathic ICH. The treatment of vascular ICH is etiologic, pathogenic, and symptomatic, but that of idiopathic ICH is only symptomatic.

  18. Pediatric intracranial primary anaplastic ganglioglioma. (United States)

    Lüdemann, Wolf; Banan, Rouzbeh; Hartmann, Christian; Bertalanffy, Helmut; Di Rocco, Concezio


    Primary intracranial anaplastic gangliogliomas are rare tumors in the pediatric patient group. Most of them present with symptoms of elevated pressure or symptomatic epilepsy. Extraaxial location is far more common than axial location. On MRI examination, they mimic pilocytic astrocytomas. The outcome after surgery depends mainly on the possible amount of surgical resection, and oncological therapy is necessary to prevent recurrence of the disease. An 11-year-old boy presented with headache and double vision due to obstructive hydrocephalus. MRI of the brain revealed an axial partially contrast enhancing lesion in the quadrigeminal plate extending from the cerebellum to the pineal gland and causing hydrocephalus. Subtotal removal of the lesion was performed, and the diagnosis of an anaplastic ganglioglioma was established and confirmed by the reference center. At the latest follow up (3 months), the boy is without any neurological symptoms and scheduled for radiation therapy as well as chemotherapy.

  19. Headache following intracranial neuroendovascular procedures. (United States)

    Baron, Eric P; Moskowitz, Shaye I; Tepper, Stewart J; Gupta, Rishi; Novak, Eric; Hussain, Muhammad Shazam; Stillman, Mark J


    Predicting who will develop post-procedure headache (PPH) following intracranial endovascular procedures (IEPs) would be clinically useful and potentially could assist in reducing the excessive diagnostic testing so often obtained in these patients. Although limited safety data exist, the use of triptans or dihydroergotamine (DHE) often raise concern when used with pre/post-coiled aneurysms. We sought to determine risk factors for PPH following IEP, to evaluate the utility of diagnostic testing in patients with post-coil acute headache (HA), and to record whether triptans and DHE have been used safely in this clinical setting. We conducted a retrospective chart review of adult patients undergoing IEPs. Bivariate analyses were conducted to compare patients who did and did not develop PPH. We reviewed records pertaining to 372 patients, of whom 263 underwent intracranial coil embolizations, 21 acrylic glue embolizations, and 88 stent placements. PPH occurred in 72% of coil patients, 33% of glue patients, and 14% of stent patients. Significant risk factors for post-coil HA were female gender, any pre-coil HA history, smoking, and anxiety/depression. A pre-stent history of HA exceeding 1 year's duration, and smoking were risk factors for post-stent HA. A pre-glue history of HA exceeding 1 year was the only risk factor for post-glue HA. In the small subgroup available for study, treatment with triptans or DHE was not associated with adverse events in pre/post-coiled aneurysms. Diagnostic testing was low yield. Occurrence of PPH was common after IEPs and especially so with coiling and in women, smokers, and those with anxiety/depression, and was often of longer duration than allowed by current International Classification of Headache Disorders-II criteria. The yield of diagnostic testing was low, and in a small subgroup treatment with triptans or DHE did not cause adverse events in pre/post-coiled aneurysms. Prospective studies are needed to confirm these findings.

  20. Occult intracranial injury in infants. (United States)

    Greenes, D S; Schutzman, S A


    The objectives of this study were as follows: (1) to determine whether clinical symptoms and signs of brain injury are sensitive indicators of intracranial injury (ICI) in infants admitted with head trauma, (2) to describe the clinical characteristics of infants who have ICI in the absence of symptoms and signs of brain injury, and (3) to determine the clinical significance of those ICIs diagnosed in asymptomatic infants. We conducted a retrospective analysis of all infants younger than 2 years of age admitted to a tertiary care pediatric hospital with acute ICI during a 6(1/2)-year period. Infants were considered symptomatic if they had loss of consciousness, history of behavior change, seizures, vomiting, bulging fontanel, retinal hemorrhages, abnormal neurologic examination, depressed mental status, or irritability. All others were considered to have occult ICI. Of 101 infants studied, 19 (19%; 95% confidence interval [CI] 12%, 28%) had occult ICI. Fourteen of 52 (27%) infants younger than 6 months of age had occult ICI, compared with 5 of 34 (15%) infants 6 months to 1 year, and none of 15 (0%) infants older than 1 year. Eighteen (95%) infants with occult ICI had scalp contusion or hematoma, and 18 (95%) had skull fracture. Nine (47%) infants with occult ICI received therapy for the ICI. No infants with occult ICI (0%) (95% CI 0, 14%) required surgery or medical management for increased intracranial pressure. Only 1 subject (5%) with occult ICI had any late symptoms or complications: a brief, self-limited convulsion. We found that 19 of 101 ICIs in infants admitted with head trauma were clinically occult. All 19 occult ICIs occurred in infants younger than 12 months of age, and 18 of 19 had skull fractures. None experienced serious neurologic deterioration or required surgical intervention. Physicians cannot depend on the absence of clinical signs of brain injury to exclude ICI in infants younger than 1 year of age.

    Currently, two radiopharmaceuticals are available in France to treat painful bone metastases Metastron for prostate cancers and Quadramet whatever is the primitive tumour. Efficacy is high since 70% of response is observed with 30% of complete response, allowing diminution and even withdrawal of antalgic medication. Toxicity is purely hematologic and is predictable in time, moderate and always transient. The interest is to use internal radiotherapy very early in the course of disease, as soon as there is one painful osseous site (and several metastatic localizations on bone scan), to treat pain, to prevent pain on other sites, and to delay recourse to other forms of therapy (such as morphinic with their side effects) and thus to ensure adequate quality of life for as long as possible.

  2. Hypertensive response to raised intracranial pressure in infancy.


    Kaiser, A M; Whitelaw, A G


    Mean arterial pressure and intracranial pressure were measured serially in six infants with intracranial hypertension (intracranial pressure greater than 20 mm Hg), and cerebral perfusion pressure was calculated from their difference. Overall, mean arterial pressure increased with rising intracranial pressure at a mean rate of 0.20 mm Hg/mm Hg. This caused a fall in cerebral perfusion pressure with increasing intracranial pressure at a mean rate of 0.80 mm Hg/mm Hg overall, although cerebral ...

  3. Managing leptomeningeal melanoma metastases in the era of immune and targeted therapy. (United States)

    Smalley, Keiran S M; Fedorenko, Inna V; Kenchappa, Rajappa S; Sahebjam, Solmaz; Forsyth, Peter A


    Melanoma frequently metastasizes to the brain, with CNS involvement being clinically evident in ∼30% of patients (as high as 75% at autopsy). In ∼5% cases melanoma cells also metastasize to the leptomeninges, the sub-arachnoid space and cerebrospinal fluid (CSF). Patients with leptomeningeal melanoma metastases (LMM) have the worst prognosis and are characterized by rapid disease progression (mean survival 8-10 weeks) and a death from neurological causes. The recent years have seen tremendous progress in the development of targeted and immune therapies for melanoma that has translated into an increased survival benefit. Despite these gains, the majority of patients fail therapy and there is a suspicion that the brain and the leptomeninges are a "sanctuary" sites for melanoma cells that escape both targeted therapy and immunologic therapies. Emerging evidence suggests that (1) Cancer cells migrating to the CNS may have unique molecular properties and (2) the CNS/leptomeningeal microenvironment represents a pro-survival niche that influences therapeutic response. In this Mini-Review, we will outline the clinical course of LMM development and will describe how the intracranial immune and cellular microenvironments offer both opportunities and challenges for the successful management of this disease. We will further discuss the latest data demonstrating the potential use of BRAF inhibitors and immune therapy in the management of LMM, and will review future potential therapeutic strategies for the management of this most devastating complication of advanced melanoma.

  4. Diffusion-weighted images of intracranial cyst-like lesions

    Magnetic resonance sequences may be designed to evaluate the diffusion movements of the protons (diffusion-weighted images, DWI). In these images, a bright signal identifies a region where the diffusion along a spatial axis is restricted. The contents of a cystic lesion frequently have the signal intensities of a generic homogeneous hyperproteinic fluid (hypointensity in T1-, hyperintensity in T2-weighted images). DWI may give further information about the microscopic organisation of these fluids: a hyperintense signal indicates the presence of a restricted diffusion, due to some kind of microscopic organisation, at the cellular or macromolecular level. This may provide additional information useful for clinical purposes. We obtained DWI in 24 consecutive patients with intracranial cystic lesions, (19 intra-axial: five abscesses, five gliomas, six metastases, two demyelinating lesions, one neurocysticercosis; five extra-axial: two arachnoid cysts, two epidermoid cysts, one cholesteatoma). We found a strongly hyperintense signal, indicating restricted diffusion, in brain abscesses, epidermoid cysts and cholesteatoma; all the remaining lesions were hypointense or mildly hyperintense. We found these data useful in critical diagnoses, such as in differentiating abscesses from tumours, and in identifying elusive tumours such as epidermoid cysts. (orig.)

  5. Intracranial radiosurgery: an effective and disruptive innovation in neurosurgery. (United States)

    Niranjan, Ajay; Madhavan, Ravindranath; Gerszten, Peter C; Lunsford, L Dade


    Physicians are guided by the teachings of their chosen field, standards of accepted practice, peer pressure, prior training, and other sources of bias. When potential bias begins to impact recommendations for care in the field of tumor management, physicians may fail to realize the importance of emerging medical innovations. Some of these ultimately turn out to be 'disruptive innovations.' These innovations are more often than not both low risk and cost effective. But the leaders in the field often initially ignore these newer technologies in favor of more mature existing technologies. However, over time these technologies gradually improve and become mainstream management practices. Intracranial radiosurgery is one such innovation which was not embraced by the neurosurgical community in the beginning. Nowadays, a wide variety of brain and body disorders are treated with radiosurgery. Acoustic neuromas and brain metastases are examples of rapidly growing indications of radiosurgery. In this report, the authors describe the emergence of stereotactic radiosurgery as a disruptive innovation in the field of medicine.

  6. National trends in radiotherapy for brain metastases at time of diagnosis of non-small cell lung cancer. (United States)

    Trifiletti, Daniel M; Sheehan, Jason P; Grover, Surbhi; Dutta, Sunil W; Rusthoven, Chad G; Kavanagh, Brian D; Sahgal, Arjun; Showalter, Timothy N


    To analyze the national trends of patients treated radiotherapy for brain metastases from non-small cell lung cancer (NSCLC) that were found at diagnosis. The National Cancer Database was queried for patients with NSCLC diagnosed from 2004 to 2013 that received brain irradiation for metastases and patients grouped into having had received fractionated brain radiotherapy (5-15 fractions with or without radiosurgery) or intracranial radiosurgery alone (1-5 fractions). Univariable and multivariable (MVA) analyses were performed to investigate factors associated with the receipt of SRS alone, and temporal/regional trends. 47,746 patients met inclusion criteria, of which 42,148 received fractionated brain irradiation (88%) and 5,598 received radiosurgery (12%). 345 patients received fractioned brain irradiation with a radiosurgical boost (0.8%). The utilization of radiosurgery-alone increased over time owing to increases in each radiosurgery modality. On MVA, several factors were associated with increased odds of receiving intracranial radiosurgery-alone over fractionated brain radiotherapy including more recent year of diagnosis, increased median income, eastern U.S. regions, further distance to the hospital, and the receipt of chemotherapy (each p<0.001). Patients of Asian descent were less likely to receive radiosurgery alone (p=0.044). In the management of brain metastases from NSCLC, overall utilization of an intracranial radiosurgery alone treatment strategy has increased over the past decade. Despite this, there appear to be significant geographic variations and disparities remain based on patient income level and race. Further study is needed to define the reasons for these disparities and appropriate actions to mitigate them. Copyright © 2017 Elsevier Ltd. All rights reserved.

    吴明灿; 刘建雄; 罗国才; 张志文; 闵杰; 余辉; 姚远


    Objective:To investigate the clinical characteristics of intracranial hematoma and the mechanism involved in its rapid natural resolution. Methods:Seventeen cases of intracranial hematoma with typical clinical and CT manifestations were retrospectively studied. Results: Intracranial hematoma was found obviously decreased in size within 72 h after its occurrence in 8 cases. The rest 9 cases presented complete resolution. Conclusions: Rapid natural resolution of acute epidural hematoma is mostly found in teenagers and the resolution is correlated with cranial fracture at the hematoma site. As for acute subdural hematoma, its rapid resolution is associated with the transfer of cerebrospinal fluid toward subdural space, the lavage effect, and the compression caused by the increased intracranial pressure or the space left resulting from redistribution of the hematoma in brain atrophy.

    Carcinosarcoma of the prostate is an uncommon malignancy with poor long-term prognosis. The cancer is typically discovered at an advanced stage, and with less than 100 reported cases, there is limited literature concerning treatment options. Our patient presented with a history of benign prostatic hypertrophy, erectile dysfunction, and nocturia. Biopsy of his prostate indicated that the patient had prostatic adenocarcinoma, but histopathology after prostatectomy revealed carcinosarcoma. It has been over six years since this patient's diagnosis of carcinosarcoma. Over this span of time, he has received a radical prostatectomy, radiotherapy, and androgen ablative therapy. The patient also developed multiple lung metastases that have been treated with video-assisted thoracic surgery and stereotactic body radiosurgery. Overall, he has remained unimpaired and in good condition despite his aggressive form of cancer.

    According to our research, this is the first case described in the literature of spontaneous intracranial epidural hematoma secondary to the use of Xarelto®. Spontaneous intracranial epidural hematomas are rarely described in the literature. They are associated with infectious diseases of the skull, coagulation disorders, vascular malformations of the dura mater and metastasis to the skull. Long-term post-marketing monitoring and independent reports will probably detect the full spectrum of hemorrhagic complications of the use of rivaroxaban. (author)

    Two cases are presented with frontal sinus pyocele and fronto-ethmoid sinus mucocele in which marked intracranial extension is shown. Their intracranial part appeared as a large biconvex mass, which showed iso or slightly low density homogeneously and had gross calcification in the posterior rim. The findings of the paranasal sinuses and the orbit in tomograms and CT scans are thought to be useful in the differential diagnosis of chronic subdural hematoma.

  20. Small RNAs in the peripheral blood discriminate metastasized from non-metastasized seminoma. (United States)

    Ruf, Christian G; Dinger, Daniela; Port, Matthias; Schmelz, Hans-Ulrich; Wagner, Walter; Matthies, Cord; Müller-Myhsok, Bertram; Meineke, Viktor; Abend, Michael


    We aimed to better discriminate metastasized (lymphogen/occult/both combined) from non-metastasized seminoma based on post-transcriptional changes examined in the peripheral blood. Total RNAs including small RNAs were isolated from the peripheral blood of patients suffering from metastasized testicular tumours (lymphogen, n = 5, clinical stage IIb/c; occult, n = 5, clinical stage I) and non-metastasized patients (n = 5, clinical stage I). Small RNA next generation sequencing (SOLID, Life Technologies) was employed to examine post-transcriptional changes. We searched for small RNAs showing at least 50 reads and a significant  ≥ 2-fold difference using peripheral blood small RNAs of non-metastasized tumours as the reference group. Candidate small RNAs were examined in univariate logistic regression analysis and combinations of two small RNAs were further examined using support vector machines. On average 1.3 x 10(7), 1.2 x 10(7) and 1.2 x 10(7) small RNA reads were detectable in non-metastasized, lymphogen and occult metastasized seminoma, respectively of which 73-76% remained after trimming. From these between 80-82% represented annotated reads and 7.2-7.8% (1.6-1.7 x 10(4)) were annotated small RNA tags. Of them 137 small RNAs showed > 50 reads and a ≥ two-fold difference to the reference. In univariate analysis we detected 33-35 different small RNAs which significantly discriminated lymphogen/occult/combined metastasized from non-metastasized seminoma and among these different comparisons it were the same small RNAs in 44-79%. Many combinations of two of these small RNAs completely discriminated metastasized from non-metastasized seminoma irrespective of the metastasis subtype. Metastasized (either lymphogen or occult) seminoma can be completely discriminated from non-metastasized seminoma with a combination of two small RNAs measured in the peripheral blood.

  1. Endobronchial metastases from extrathoracic malignancies. (United States)

    Endobronchial metastases (EBM) from extrapulmonary malignant tumors are rare. The most common extrathoracic malignancies associated with EBM are breast, renal and colorectal carcinomas. In this study, we aimed to evaluate the clinical, radiographic and bronchoscopic aspects of patients with EBM who were diagnosed between 1992 and 2002. Data about patients' clinical conditions, symptoms, radiographic and endoscopic findings, and histopathological examination results were investigated. EBM was defined as bronchoscopically visible lesions histopathologically identical to the primary tumor in patients with extrapulmonary malignancies. We found 15 cases with EBM. Primary tumors included breast (3), colorectal (3), and renal (2) carcinomas; Malignant Melanoma (2); synovial sarcoma (1), ampulla of Vater adenocarcinoma (1), pheochromocytoma (1), hypernephroma (1), and Hodgkin's Disease (1). The most common symptoms were dyspnea (80%), cough (66.6%) and hemoptysis (33.3%). Multiple (40%) or single (13.3%) pulmonary nodules, mediastinal or hilar lymphadenopathy (40%), and effusion (40%) were the most common radiographic findings. The mean interval from initial diagnosis to diagnosis of EBM was 32.8 months (range, 0-96 months) and median survival time was 18 months (range, 4-84). As a conclusion, various extrapulmonary tumors can metastasize to the bronchus. Symptoms and radiographic findings are similar with those in primary lung cancer. Therefore, EBM should be discriminated from primary lung cancer histopathologically. Although mean survival time is usually short, long-term survivors were reported. Consequently, treatment must be planned according to the histology of the primary tumor, evidence of metastasis to other sites and medical status of the patient.

  2. A Study on Role of Magnetic Resonance Imaging (MRI in Intracranial Space Occupying Lesions

    Directory of Open Access Journals (Sweden)

    Bhavesh Ramjibhai Goyani


    Full Text Available Background: The high morbidity and mortality associated with Intracranial Space Occupying Lesions necessitates their early diagnosis so as to plan the intervention that is required. In the present study cases of either clinically suspected brain space occupying lesions or already diagnosed cases of brain space occupying lesions were studied by cross sectional imaging of MRI. Methodology: The present cross-sectional study was conducted presented with symptoms of raised ICT of sub acute onset and had lateralizing sign. A semi-structured questionnaire was prepared and demographic and clinical data like age, sex, symptoms and various morphological characters of Supratentorial SOLs were studied. A clinico-radiological correlation and confirmation of Radiological diagnosis was done by biopsy/surgery/MRI whenever possible to minimize patient follow up. Results: Majority of the patients were in the fourth decade (28.5%. Metastases were the most common single group of intracranial space occupying lesion (27%, Gliomas were the most common brain tumors (31.4%. Of the Gliomas, astrocytomas accounted for (81.8%. Most common hemisphere to be involved was the parietal lobe (31.4%. Intra-axial involvement (78.58 % was most common localization in present study. Edema was the most common associated MRI finding (74.3%. Conclusion: The diagnostic accuracy of MRI in evaluation of intracranial space occupying lesion was 98.57 %. MRI remains the first line investigation for diagnosing and evaluation Intracranial space occupying lesion with a reasonable degree of diagnostic accuracy and with the advent of newer modifications of MRI such as MR Spectroscopy, 3-Tesla MRI, and newer techniques like MR Perfusion.

    Eighteen tumor samples from 11 patients with metastatic colorectal cancer were cytogenetically analyzed after short-term culturing. Of the 13 metastases examined, 11 were from lymph nodes, 1 from the peritoneum and 1 from the lung. In 5 of the 11 patients, matched samples from the primary tumor...... and lymph node metastases were analyzed. Cytogenetic similarities between the primary and secondary lesions were found in all 5 cases, indicating that many of the chromosomal aberrations presumably occurred before disease spreading took place. Compared with the primaries, the metastases appeared to exhibit...

  5. Targeting Brain Metastases in Patients with Melanoma

    Directory of Open Access Journals (Sweden)

    Dionysis Papadatos-Pastos


    Full Text Available Patients with brain metastases from malignant melanoma historically have a very poor outcome. Surgery and radiotherapy can be used, but for the majority of patients the disease will progress quickly. In the recent past, patients with brain metastases derived only minimal benefit from cytotoxic chemotherapy. Novel therapies that have been shown to be superior to chemotherapy in metastatic melanoma have made their way in clinic and data regarding their use in patients with treated or untreated brain metastases are encouraging. In this paper we describe the use of vemurafenib, dabrafenib, and ipilimumab in patients with melanoma disseminated to the brain in addition to other treatments currently in development.

  7. Occurrence studies of intracranial tumours

    Energy Technology Data Exchange (ETDEWEB)

    Larjavaara, S.


    Intracranial tumours are a histopathologically heterogeneous group of tumours. This thesis focused on three types of intracranial tumours; gliomas, meningiomas and vestibular schwannomas (VS). The main objectives of the dissertation were to estimate the occurrence of intracranial tumours by different subtypes, and to assess the validity and completeness of the cancer registry data. The specific aims of the publications were to evaluate the validity of reported incidence rates of meningioma cases, to describe the trends of VS incidence in four Nordic countries, and to define the anatomic distribution of gliomas and to investigate their location in relation to mobile phone use. Completeness of meningioma registration was examined by comparing five separate sources of information, and by defining the frequencies of cases reported to the Finnish Cancer Registry (FCR). Incidence trends of VS were assessed in the four Nordic countries over a twenty-one-year period (1987 - 2007) using cancer registry data. The anatomic site of gliomas was evaluated using both crude locations in the cerebral lobes and, in more detail, a three-dimensional (3D) distribution in the brain. In addition, a study on specific locations of gliomas in relation to the typical position of mobile phones was conducted using two separate approaches: a case-case and a case-specular analysis. The thesis was based on four sets of materials. Data from the international Interphone study were used for the studies on gliomas, while the two other studies were register-based. The dataset for meningiomas included meningioma cases from the FCR and four clinical data sources in Tampere University Hospital (neurosurgical clinic, pathology database, hospital discharge register and autopsy register). The data on VS were obtained from the national cancer registries of Denmark, Finland, Norway and Sweden. The coverage of meningiomas was not comprehensive in any of the data sources. The completeness of FCR was

  9. Pulmonary nodules and metastases in colorectal cancer

    DEFF Research Database (Denmark)

    Nordholm-Carstensen, Andreas


    Patients with newly diagnosed colorectal cancer (CRC) are subjected to a preoperative thoraco-abdominal CT scan to determine the cancer stage. This staging is of relevance with regard to treatment and prognosis. About 20% of the patients have distant metastatic spread at the time of diagnosis, i.......e. synchronous metastases. Most common are hepatic metastases followed by pulmonary involvement. The optimal staging modality for detecting synchronous pulmonary metastases is debated. It has been argued, that synchronous pulmonary metastases (SPCM) are rare in CRC and that the consequence of detecting SPCM...... is minimal. Furthermore, the current staging practice is complicated by a high number of incidental findings on the thoracic CT, so-called indeterminate pulmonary nodules (IPN). IPN can potentially represent SPCM. The purpose of this thesis was to estimate the prevalence, characteristics and clinical...

  13. Management of disappearing colorectal liver metastases. (United States)

    Kuhlmann, K; van Hilst, J; Fisher, S; Poston, G


    The development of new potent systemic treatment modalities has led to a significant increase in survival of patients with colorectal liver metastases. In the neo-adjuvant setting, these modalities can be used for patient selection, down staging, and conversion from non-resectable to resectable liver metastases. In addition, complete radiological disappearance of metastases can occur, the phenomenon of disappearing liver metastases. Because only a small percentage of these patients (0-8%) have a complete radiological response of all liver metastases, most patients will undergo surgery. At laparotomy, local residual disease at the site of the disappeared metastasis is still found in 11-67%, which highlights the influence of the imaging modalities used at (re)staging. When the region of the disappeared liver metastasis was resected, microscopically residual disease was found in up to 80% of the specimens. Alternatively, conservative management of radiologically disappeared liver metastases resulted in 19-74% local recurrence, mostly within two years. Obviously, these studies are highly dependent on the quality of the imaging modalities utilised. Most studies employed CT as the modality of choice, while MRI and PET was only used in selective series. Overall, the phenomenon of disappearing liver metastases seems to be a radiological rather than an actual biological occurrence, because the rates of macroscopic and microscopic residual disease are high as well as the local recurrence rates. Therefore, the disappeared metastases still require an aggressive surgical approach and standard (re)staging imaging modalities should include at least CT and MRI. Copyright © 2016 Elsevier Ltd.

    Asifa Andleeb


    Full Text Available Background: Brain metastases represent an important cause of morbidity for cancer patients. Its incidence has increased overall overtime as a consequence of improved detection by magnetic resonance imaging (MRI. However, in Indian literature, scant data are available. At this moment, we have analyzed our data from a single tertiary care center in North India. The purpose of the study was to analyze the clinical profile of patients with brain metastases. A retrospective study from a single tertiary care center. Patients and Methods: A retrospective review of records of all patients who were registered in hospital-based cancer registry and developed brain metastases from June 2011 to June 2013 yielded 95 patients for analyses. Results: Majority of cases were seen in the 6th decade of life. Lung cancer was the most common primary followed by breast. On imaging (computed tomography or MRI, multiple lesions were more common than single. Most of the patients presented with a headache (37.9%. Supratentorial involvement was seen in 87.3% against 12.6% infratentorial involvement. Median time interval from diagnosis of primary and development of brain metastases was 13.8 months. A median survival of only 3 months was seen after development of brain metastases. Conclusion: The present study highlights that brain metastases occur mainly in elderly people with lung being the most common primary malignancy. It is a deadly event with a median survival of only 3 months.

  16. The Analysis of Erlotinib on Brain Metastases in Patients with Non-small-cell Lung Cancer

    Directory of Open Access Journals (Sweden)

    Baohui HAN


    Full Text Available Background and objective Brain metastases are common in non-small-cell lung cancer (NSCLC and the prognosis is poor. Erlotinib is a specific inhibitor of the epidermal growth factor receptor-associated tyrosine kinase (EGFRTKI, which has been gradually used in the treatment for advanced NSCLC. The aim of this study is to evaluate the antitumor efficacy and its relevant factors of erlotinib in NSCLC patients with brain metastases. Methods The clinical data of 30 NSCLC patients with brain metastases were reviewed retrospectively. All of them were treated with erlotinib, given orally 150mg daily. These patients discontinued administration of erlotinib until disease progression, death or intolerable side effects. Results In terms of intracranial lesions, partial response (PR was observed in 2 patients (6.7%, with stable disease (SD in 17 patients (56.7%, for overall disease control rate (DCR of 63.4%. As for systemic disease, PR was observed in 2 patients (6.7%, with SD in 5 patients (16.7%, for overall DCR of 23.4%. There was no statistical difference in DCR among different subtypes of age, gender, smoking history, histology, PS score, the number of brain metastases, the onset of brain metastases, chemotherapy, brain radiotherapy and side effects. The median time to disease progression (MTTP and median survival time (MST was 2.4 months and 7.7 months respectively. The 1 and 2 year survival rate was 38.4% and 15.2%. The univariate analysis showed that the survival time was related to the patients’ PS score, smoking history, brain radiotherapy and chemotherapy. The multivariate analysis indicated that brain radiotherapy was the independent prognostic factor and the relationship between the survival time and smoking history was near to statistical significance. Conclusion The patients receiving brain radiotherapy may have better survival benefit. Non-smokers have a trend to survive longer than smokers. Erlotinib may be effective on brain metastases

    Full Text Available Background : Characteristics of intracranial aneurysms display ethnic variations. Data on this disease from the African continent is scarce and often conflicting. Aim : To describe site, age and gender distribution of intracranial aneurysms among Kenyans. Study Design and Setting : Retrospective study at Kenyatta National Hospital, Kenya. Materials and Methods: All records of black African patients with a diagnosis of intracranial aneurysms seen at Kenyatta National Hospital, the largest referral hospital in the Eastern and Central African region, over the period from January 1998 to December 2007 were examined for site, age and gender distribution. The data gathered were coded, analyzed with SPSS 11.50. Results : Fifty-six cases of intracranial aneurysms were analyzed. The posterior communicating artery was the most affected (35.7%, followed by the anterior communicating artery (26.8%, while the posterior cerebral artery was the least affected (2%. Multiple aneurysms were present in 2%. The mean age at presentation was 50.9 years (range 21-80 years and the gender distribution was equal. Conclusions : Intracranial aneurysms among Kenyans occur most commonly on the posterior communicating artery, in young individuals, and without gender bias. The distribution differs from that described in the literature and this requires search for risk factors.

  18. Hyperprolactinemia due to spontaneous intracranial hypotension. (United States)

    Schievink, Wouter I; Nuño, Miriam; Rozen, Todd D; Maya, M Marcel; Mamelak, Adam N; Carmichael, John; Bonert, Vivien S


    OBJECT Spontaneous intracranial hypotension is an increasingly recognized cause of headaches. Pituitary enlargement and brain sagging are common findings on MRI in patients with this disorder. The authors therefore investigated pituitary function in patients with spontaneous intracranial hypotension. METHODS Pituitary hormones were measured in a group of 42 consecutive patients with spontaneous intracranial hypotension. For patients with hyperprolactinemia, prolactin levels also were measured following treatment. Magnetic resonance imaging was performed prior to and following treatment. RESULTS The study group consisted of 27 women and 15 men with a mean age at onset of symptoms of 52.2 ± 10.7 years (mean ± SD; range 17-72 years). Hyperprolactinemia was detected in 10 patients (24%), ranging from 16 ng/ml to 96.6 ng/ml in men (normal range 3-14.7 ng/ml) and from 31.3 ng/ml to 102.5 ng/ml in women (normal range 3.8-23.2 ng/ml). In a multivariate analysis, only brain sagging on MRI was associated with hyperprolactinemia. Brain sagging was present in 60% of patients with hyperprolactinemia and in 19% of patients with normal prolactin levels (p = 0.02). Following successful treatment of the spontaneous intracranial hypotension, hyperprolactinemia resolved, along with normalization of brain MRI findings in all 10 patients. CONCLUSIONS Spontaneous intracranial hypotension is a previously undescribed cause of hyperprolactinemia. Brain sagging causing distortion of the pituitary stalk (stalk effect) may be responsible for the hyperprolactinemia.

  19. [Lymph node and distant metastases of thyroid gland cancer. Metastases in the thyroid glands]. (United States)

    Schmid, K W


    The different biological features of the various major entities of thyroid cancer, e.g. papillary, follicular, poorly differentiated, anaplastic and medullary, depend to a large extent on their different metastatic spread. Papillary thyroid cancer (PTC) has a propensity for cervical lymphatic spread that occurs in 20-50 % of patients whereas distant metastasis occurs in thyroid cancer (FTC) has a marked propensity for vascular but not lymphatic invasion and 10-20 % of FTC develop distant metastases. At the time of diagnosis approximately one third of medullary thyroid cancer (MTC) cases show lymph node metastases, in 10-15 % distant metastases and 25 % develop metastases during the course of the disease. Poorly differentiated (PDTC) and anaplastic thyroid cancer (ATC) spread via both lymphatic and vascular invasion. Thus distant metastases are relatively uncommon in DTC and when they occur, long-term stable disease is the typical clinical course. The major sites of distant metastases are the lungs and bone. Metastases to the brain, breasts, liver, kidneys, muscle and skin are relatively rare or even rare. The thyroid gland itself can be a site of metastases from a variety of other tumors. In autopsy series of patients with disseminated cancer disease, metastases to the thyroid gland were found in up to 10 % of cases. Metastases from other primary tumors to the thyroid gland have been reported in 1.4-3 % of patients who have surgery for suspected cancer of the thyroid gland. The most common primary cancers that metastasize to the thyroid gland are renal cell (48.1 %), colorectal (10.4 %), lung (8.3 %) and breast cancer (7.8 %) and surprisingly often sarcomas (4.0 %).

    Full Text Available Background and objective There is no high-level evidence for the time of whole brain radiotherapy (WBRT for patients with epidermal growth factor receptor (EGFR-mutated non-small cell lung cancer (NSCLC and brain metastases. The aim of this study is to assess the appropriate timing of WBRT for patients with EGFR-mutated NSCLC and brain metastases (BM. Methods There were 78 patients diagnosed with EGFR-mutated NSCLC and BM in Beijing Chest Hospital between August 2009 and May 2015. 48 untreated patients who received both WBRT and EGFR-tyrosine kinase inhibitors (TKIs therapy. Prognostic factors of intracranial progression-free survival (PFS and overall survival (OS were identified by Cox proportional hazards modeling. Results Intracranial objective response rate was 81.3% and disease control rate was 93.8%. Median intracranial PFS was 10 months. Median OS was 18 months. Multivariate analysis of intracranial PFS revealed that Eastern Cooperative Oncology Group (ECOG performance status (PS 0-1 (HR=30.436, 95%CI: 4.721-196.211, P<0.001 and early WBRT (HR=3.663, 95%CI: 1.657-8.098, P=0.001 had a better intracranial PFS. Multivariate analysis of OS revealed that PS 0-1 (HR=57.607, 95%CI: 6.135-540.953, P<0.001, early WBRT (HR=2.757, 95%CI: 1.140-6.669, P=0.024, and stereotactic radiosurgery (HR=5.964, 95%CI: 1.895-18.767, P=0.002 were independent prognostic factors of OS. Conclusion Early WBRT combined with EGFR-TKIs can improve outcomes of patients with EGFR-mutated NSCLC and BM, but it needs to be confirmed by large-sample-size and multicenter prospective clinical trials.

    Aylward, Shawn C; Aronowitz, Catherine; Reem, Rachel; Rogers, David; Roach, E Steve


    We aimed to determine the frequency of intracranial hypertension without headache in children. We retrospectively analyzed patients evaluated in a pediatric intracranial hypertension referral center. Patients were divided into 2 groups depending on whether they complained of headache at the time of presentation. Age, body mass index, and opening cerebrospinal fluid pressures were considered continuous variables and compared by Wilcoxon rank-sum test because of non-normality. A P value of .05 was considered significant. A total of 228 charts were reviewed; 152 patients met the criteria for intracranial hypertension and 22/152 patients (14.5%) met the criteria of optic nerve edema without headache. There were clinically significant differences in age and body mass index between the 2 groups. The group without headache was typically younger and not obese. The opening pressure and modified opening pressure were not clinically significant between the 2 groups. © The Author(s) 2014.

  4. Are the Intracranial Lipomas Always Asymptomatic?

    Directory of Open Access Journals (Sweden)

    Mustafa Yilmaz


    Full Text Available Intracranial lipomas are rarely observed, and accepted as the congenital lesion of central nervous system. Intracranial lipomas are usually based centrally and have benign character. In the brain, it is mostly localized in pericallosal region, quadrigeminal system, and suprasellar region and cerebellopontine angles. As being mostly asymptomatic, the patients occasionally constitute clinical symptoms according to localization area. These symptoms are systemic symptoms such as cephalalgia, drowsiness, crisis and ataxy. In this article, we aimed to present the intracranial lipomas phenomenon which was diagnosed to have caused ptosis and upper lateral sight problem, namely causing localized neurological symptom, situated in mesencephalon and having pressure effect, regarding a 57-year old male patient brought to the emergency service with the nausea, throwing up and cephalalgia ailments.

    Directory of Open Access Journals (Sweden)



    Full Text Available In this retrospective study, 47 patients with clinical diagnosis of central nervous system metastases of breast cancer were evaluated by computerized tomography (CT, magnetic resonance imaging (MRI and cerebrospinal fluid (CSF examination. The patients were divided in 2 groups: 1, without leptomeningeal neoplasm and 2, with leptomeningeal neoplasm. In the group 2, the time interval between the primary disease and the central nervous system metastasis as well as the survival time were shorter than in group 1 (40 and 4.3 months in group 2 versus 57 and 10 months respectively, in group 1. In both groups the most common neurological symptoms and signs were intracranial hypertension and motor deficits. The most sensitive diagnostic methods were CT and MRI in group 1, and the CSF examination in group 2. The use of the tumor markers CEA and CA-15.3 in the routine examination of CSF showed promising results, mainly in leptomeningeal forms.

[Department of Therapeutic Radiology and Oncology, Medical University of Graz, Graz (Austria)


    Purpose: To determine prognostic factors that allow the selection of melanoma patients with advanced intra- and extracerebral metastatic disease for palliative whole-brain radiation therapy (WBRT) or best supportive care. Methods and Materials: This was a retrospective study of 87 patients who underwent palliative WBRT between 1988 and 2009 for progressive or multiple cerebral metastases at presentation. Uni- and multivariate analysis took into account the following patient- and tumor-associated factors: gender and age, Karnofsky performance status (KPS), neurologic symptoms, serum lactate dehydrogenase (LDH) level, number of intracranial metastases, previous resection or stereotactic radiosurgery of brain metastases, number of extracranial metastasis sites, and local recurrences as well as regional lymph node metastases at the time of WBRT. Results: In univariate analysis, KPS, LDH, number of intracranial metastases, and neurologic symptoms had a significant influence on overall survival. In multivariate survival analysis, KPS and LDH remained as significant prognostic factors, with hazard ratios of 3.3 (95% confidence interval [CI] 1.6-6.5) and 2.8 (95% CI 1.6-4.9), respectively. Patients with KPS ≥70 and LDH ≤240 U/L had a median survival of 191 days; patients with KPS ≥70 and LDH >240 U/L, 96 days; patients with KPS <70 and LDH ≤240 U/L, 47 days; and patients with KPS <70 and LDH >240 U/L, only 34 days. Conclusions: Karnofsky performance status and serum LDH values indicate whether patients with advanced intra- and extracranial tumor manifestations are candidates for palliative WBRT or best supportive care.

  12. Stereotactic radiosurgery for multiple brain metastases (United States)

    Lee, Anna; (Josh Yamada, Yoshiya


    Whole brain radiation therapy has been the traditional treatment of choice for patients with multiple brain metastases. Although stereotactic radiosurgery is widely accepted for the management to up to 4 brain metastases, its use is still controversial in cases of 5 or more brain metastases. Randomized trials have suggested that stereotactic radiosurgery alone is appropriate in up to 4 metastases without concomitant whole brain radiation. Level 1 evidence also suggests that withholding whole brain radiation may also reduce the impact of radiation on neurocognitive function and also may even offer a survival advantage. A recent analysis of a large multicentre prospective database has suggested that there are no differences in outcomes such as the likelihood of new metastasis or leptomeningeal disease in cases of 2-10 brain metastases, nor in overall survival. Hence in the era of prolonged survival with stage IV cancer, stereotactic radiosurgery is a reasonable alternative to whole brain radiation in order to minimize the impact of treatment upon quality of life without sacrificing overall survival.

  13. Benign Metastasizing Pleomorphic Adenoma: A Case Report

    Directory of Open Access Journals (Sweden)



    Full Text Available Introduction Pleomorphic adenoma (mixed tumor is the most common neoplasm of the salivary gland. It is usually a benign, slow-growing and well-circumscribed tumor. However, there are rare reports of a subset of these tumors metastasizing to distant sites without undergoing malignant transformation. Here we describe a case of pleomorphic adenoma of the parotid gland that metastasied to the cervical lymph node coincidentally with similar appearance of the primary lesion in the ipsilateral parotid gland. Case Presentation A 78-year-old male with right sided cervical lymph node and ipsilateral parotid mass from one year ago came to Imam Khomeini hospital. Physical examination, a painless firm mass was found within year, the parotid and lymph node of the neck concomitantly with no other organs abnormalities. A diagnosis of pleomorphic adenoma was made from completion parotidectomy and cervical lymphadenectomy. No histologic characteristic of malignancy were seen in either specimen; therefore a diagnosis of benign metastasizing mixed tumor was rendered. Discussion Benign metastasizing pleomorphic adenoma is a rare and controversial but distinct clinical entity. Although the definition of the term benign precludes metastatic disease, these tumors do not demonstrate any malignant features yet metastasized to distinct sites. It remains to be determined whether this benign metastasizing pleomorphic adenoma is really low grade salivary malignancy.

    Purpose: To report the outcomes of repeat stereotactic radiosurgery (SRS), deferring whole-brain radiation therapy (WBRT), for distant intracranial recurrences and identify factors associated with prolonged overall survival (OS). Patients and Methods: We retrospectively identified 652 metastases in 95 patients treated with 2 or more courses of SRS for brain metastases, deferring WBRT. Cox regression analyzed factors predictive for OS. Results: Patients had a median of 2 metastases (range, 1-14) treated per course, with a median of 2 courses (range, 2-14) of SRS per patient. With a median follow-up after first SRS of 15 months (range, 3-98 months), the median OS from the time of the first and second course of SRS was 18 (95% confidence interval [CI] 15-24) and 11 months (95% CI 6-17), respectively. On multivariate analysis, histology, graded prognostic assessment score, aggregate tumor volume (but not number of metastases), and performance status correlated with OS. The 1-year cumulative incidence, with death as a competing risk, of local failure was 5% (95% CI 4-8%). Eighteen (24%) of 75 deaths were from neurologic causes. Nineteen patients (20%) eventually received WBRT. Adverse radiation events developed in 2% of SRS sites. Conclusion: Multiple courses of SRS, deferring WBRT, for distant brain metastases after initial SRS, seem to be a safe and effective approach. The graded prognostic assessment score, updated at each course, and aggregate tumor volume may help select patients in whom the deferral of WBRT might be most beneficial.

    This study aimed to determine factors allowing the prediction of extracranial metastases in patients presenting with brain metastases at the first diagnosis of cancer. Data from 659 patients with brain metastases upon first diagnosis of cancer were retrospectively analyzed. The parameters age, gender, Karnofsky performance score (KPS), primary tumor type and number of brain metastases were compared between 359 patients with extracranial metastases and 300 patients without extracranial metastases. Additional analyses were performed for patients with the most unfavorable and those with the most favorable characteristics. The comparison of patients with versus without extracranial metastases revealed significant differences between the groups in terms of KPS (p < 0.001) and number of brain metastases (p < 0.001). Of the study patients, 113 had both most unfavorable characteristics, i.e. KPS ≤ 50 and ≥ 4 brain metastases. The sensitivity for identifying patients with extracranial metastases was 82 %; specificity was 51 %. A total of 50 patients had KPS ≥ 90 and only one brain metastasis. The sensitivity for identifying patients without extracranial metastases was 86 %; specificity was 58 %. The combination of KPS and the number of brain metastases can help to predict the presence or absence of extracranial metastases. (orig.)

    Frenzel, Laurent; Javier, Rose-Marie; Eichler, Francoise; Zollner, Goerg; Sibilia, Jean


    Bone metastases are usually seen on imaging studies as lytic lesions and less often as sclerotic or mixed lesions. We report an exceedingly unusual case of breast cancer identified after magnetic resonance imaging showed bone metastases with fluid-fluid levels in the spine and sacrum. Bone images containing fluid-fluid levels are usually solitary abnormalities produced by aneurismal bone cysts. The fluid-fluid level is due to bleeding within the tumor followed by layering of the blood components based on density differences. Only two other cases of bone metastases with multiple fluid-fluid levels have been reported. Although fluid-fluid levels are exceedingly rare, clinicians should be aware that they might indicate a malignancy, particularly when they are multiple.

    Skeletal metastasis in carcinoma cervix occurs in about 0.8-23% of cases. These lesions are usually radiographically lytic. Very few cases of metastases to the skull have been identiifed, about 5 cases to the best of our knowledge. We present a case of adenosquamous cell carcinoma of cervix with fat attenuating skull metastases in a 38-year-old lady that is not reported till date. The lesion was lytic, expansile and with negative attenuation of -15 to -30 Hounsifeld units corresponding to fat.Metastases must be included in the differentials of scalp lesions. A history of recent onset of swelling and associated lytic areas in calvarium on contrast enhanced computed tomography with multiplicity can give a clue to metastatic nature of disease.

    Melanomas have a high rate of brain metastases. Both the functional prognosis and the overall survival are poor in these patients. Until now, surgery and radiotherapy represented the two main modalities of treatment. Nevertheless, due to the improvement in the management of the extracerebral melanoma, the systemic treatment may be an option in patients with brain metastases. Immunotherapy with anti-CTLA4 (cytotoxic T-lymphocyte-associated protein 4) - ipilimumab - or BRAF (serine/threonine-protein kinase B-raf) inhibitors - vemurafenib, dabrafenib - has shown efficacy in the management of brain metastases in a- or pauci-symptomatic patients. Studies are ongoing with anti-PD1 (programmed cell death 1) and combinations of targeted therapies associating anti-RAF (raf proto-oncogene, serine/threonine kinase) and anti-MEK (mitogen-activated protein kinase kinase).

    Bone metastases have a major impact on morbidity and on mortality in cancer patients. Despite its clinical relevance, metastasis remains the most poorly elucidated aspect of carcinogenesis. The biological mechanisms leading to bone metastasis establishment have been referred as "vicious circle," a complex network between cancer cells and the bone microenvironment. This review is aimed to underline the new molecular targets in bone metastases management other than bisphosphonates. Different pathways or molecules such as RANK/RANKL/OPG, cathepsin K, endothelin-1, Wnt/DKK1, Src have recently emerged as potential targets and nowadays preclinical and clinical trials are underway. The results from those in the advanced clinical phases are encouraging and underlined the need to design large randomised clinical trials to validate these results in the next future. Targeting the bone by preventing skeletal related events (SREs) and bone metastases has major clinical impact in improving survival in bone metastatic patients and in preventing disease relapse in adjuvant setting.

  20. Treatment of breast cancer brain metastases. (United States)

    Hofer, Silvia; Pestalozzi, Bernhard C


    Breast cancer represents the second most frequent cause of brain metastases. Treatment planning should consider several tumor and patient factors to estimate prognosis based on the Karnofsky Performance Status (KPS), age, extent of extra-cerebral disease as well as genetic subtype. When systemic disease is under control patients with up to three metastases qualify for local therapy, such as surgical excision or stereotactic radiotherapy. After the local treatment the addition of whole brain radiation therapy may be postponed until disease progression in the brain is observed and overall survival will not be compromised. Asymptomatic brain metastases may be first approached with a systemic treatment to which the primary tumor is considered to be sensitive.

    Full Text Available Secondary symptomatic gastrointestinal metastases from lung primary tumor are rare. They can cause a variety of clinical conditions such as perforation, obstruction and bleeding. Intestinal perforations of intestinal metastases have a very poor prognosis. We present a case of a patient with metastatic lung cancer who presents with intestinal perforation and pneumoperitoneum. A 67 year old male, immunosuppressed and smoker is diagnosed with acute abdomen secondary to perforation of a tumor of the terminal ileum, as well as three other similar injuries. Resection and anastomosis. The patient died two months after surgery. The final pathological diagnosis supports epidermoidide poorly differentiated lung carcinoma. It was concluded that given an intestinal perforation in a patient diagnosed with lung carcinoma, it shouldn´t be excluded the metastases origen . Surgery is a purely palliative procedure.

  2. Strategies for Management of Synchronous Colorectal Metastases. (United States)

    Castellanos, Jason A; Merchant, Nipun B


    The management of synchronous presentation of colorectal cancer and liver metastases has long been a topic of debate and discussion for surgeons due to the unique dilemma of balancing operative timing along with treatment strategy. Operative strategies for resection include staged resection with colon first approach, "reverse" staged resection with liver metastases resected first, and one-stage, or simultaneous, resection of both the primary tumor and liver metastases approach. These operative strategies can be further augmented with perioperative chemotherapy and other novel approaches that may improve resectability and patient survival. The decision on operative timing and approach, however, remains largely dependent on the surgeon's determination of disease resectability, patient fitness, and the need for neoadjuvant chemotherapy.

  7. Diagnosis and evaluation of intracranial arteriovenous malformations (United States)

    Conger, Andrew; Kulwin, Charles; Lawton, Michael T.; Cohen-Gadol, Aaron A.


    Background: Ideal management of intracranial arteriovenous malformations (AVMs) remains poorly defined. Decisions regarding management of AVMs are based on the expected natural history of the lesion and risk prediction for peritreatment morbidity. Microsurgical resection, stereotactic radiosurgery, and endovascular embolization alone or in combination are all viable treatment options, each with different risks. The authors attempt to clarify the existing literature's understanding of the natural history of intracranial AVMs, and risk-assessment grading scales for each of the three treatment modalities. Methods: The authors conducted a literature review of the existing AVM natural history studies and studies that clarify the utility of existing grading scales available for the assessment of peritreatment risk for all three treatment modalities. Results: The authors systematically outline the diagnosis and evaluation of patients with intracranial AVMs and clarify estimation of the expected natural history and predicted risk of treatment for intracranial AVMs. Conclusion: AVMs are a heterogenous pathology with three different options for treatment. Accurate assessment of risk of observation and risk of treatment is essential for achieving the best outcome for each patient. PMID:25984390

  9. Differentiating Concussion From Intracranial Pathology in Athletes. (United States)

    Cripps, Andrea; Livingston, Scott C


    Clinical Scenario: A cerebral concussion is a traumatically induced transient disturbance of brain function characterized by a complex pathophysiologic process and is classified as a subset of mild traumatic brain injury. The occurrence of intracranial lesions after sport-related head injury is relatively uncommon, but the possibility of serious intracranial injury (ICI) should be included in the differential diagnosis. ICIs are potentially life threatening and necessitate urgent medical management; therefore, prompt recognition and evaluation are critical to proper medical management. One of the primary objectives of the initial evaluation is to determine if the concussed athlete has an acute traumatic ICI. Athletic trainers must be able promptly recognize clinical signs and symptoms that will enable them to accurately differentiate between a concussion (ie, a closed head injury not associated with significant ICI) and an ICI. The identification of predictors of intracranial lesions is, however, relatively broad. Focused Clinical Question: Which clinical examination findings (ie, clinical signs and symptoms) indicate possible intracranial pathology in individuals with acute closed head injuries?

    Divya Nandwani, OD


    Full Text Available Background: Idiopathic intracranial hypertension (IIH presents differently in prepubertal children as compared to postpubertal children and adults. In adults, IIH is most common in obese women of child-bearing age. However, when occurring in prepubertal children, IIH has been shown to have no predilection for gender and does not correlate with obesity. This case report exemplifies the rare occurrence of IIH in a pediatric patient. Case Report: A five-year-old Hispanic female patient was seen at the University Eye Center for a longstanding hypotropia secondary to a likely congenital fourth nerve palsy with an exotropia component. After a strabismus surgery and a series of follow-up visits, bilateral swollen optic nerves were observed, and a prompt referral to the emergency room was made. Consequently, she was diagnosed with IIH. A treatment regimen of acetazolamide was initiated with subsequent improvement of the clinical presentation of increased intracranial pressure, confirmed by the reduction of swelling of her optic nerves. Conclusions: Bilateral swelling of the optic nerves can be an emergency, especially in children. It is important urgently to rule out causes for increased intracranial pressure. If treatment is significantly delayed, or if no treatment is given to a patient with this condition, loss of visual function may occur. In addition to reporting a rare circumstance of pediatric idiopathic intracranial hypertension, this case report serves to remind eye care practitioners of the importance of monitoring the ocular health of patients closely, even in young, healthy children.

    Purpose: Radiation therapy following resection of a brain metastasis increases the probability of disease control at the surgical site. We analyzed our experience with postoperative stereotactic radiosurgery (SRS) as an alternative to whole-brain radiotherapy (WBRT), with an emphasis on identifying factors that might predict intracranial disease control and overall survival (OS). Methods and Materials: We retrospectively reviewed all patients through December 2008, who, after surgical resection, underwent SRS to the tumor bed, deferring WBRT. Multiple factors were analyzed for time to intracranial recurrence (ICR), whether local recurrence (LR) at the surgical bed or “distant” recurrence (DR) in the brain, for time to WBRT, and for OS. Results: A total of 49 lesions in 47 patients were treated with postoperative SRS. With median follow-up of 9.3 months (range, 1.1-61.4 months), local control rates at the resection cavity were 85.5% at 1 year and 66.9% at 2 years. OS rates at 1 and 2 years were 52.5% and 31.7%, respectively. On univariate analysis (preoperative) tumors larger than 3.0 cm exhibited a significantly shorter time to LR. At a cutoff of 2.0 cm, larger tumors resulted in significantly shorter times not only for LR but also for DR, ICR, and salvage WBRT. While multivariate Cox regressions showed preoperative size to be significant for times to DR, ICR, and WBRT, in similar multivariate analysis for OS, only the graded prognostic assessment proved to be significant. However, the number of intracranial metastases at presentation was not significantly associated with OS nor with other outcome variables. Conclusions: Larger tumor size was associated with shorter time to recurrence and with shorter time to salvage WBRT; however, larger tumors were not associated with decrements in OS, suggesting successful salvage. SRS to the tumor bed without WBRT is an effective treatment for resected brain metastases, achieving local control particularly for tumors up to

    An intracranial aneurysm, with or without subarachnoid hemorrhage (SAH), is a relevant health problem. The rupture of an intracranial aneurysm is a critical concern for individual health; even an unruptured intracranial aneurysm is an anxious condition for the individual. The aim of this guideline is to present current and comprehensive recommendations for the management of intracranial aneurysms, with or without rupture. We performed an extensive literature search, using Medline. We met in person to discuss recommendations. This document is reviewed by the Task Force Team of the Korean Society of Interventional Neuroradiology (KSIN). We divided the current guideline for ruptured intracranial aneurysms (RIAs) and unruptured intracranial aneurysms (UIAs). The guideline for RIAs focuses on diagnosis and treatment. And the guideline for UIAs focuses on the definition of a high-risk patient, screening, principle for treatment and selection of treatment method. This guideline provides practical, evidence-based advice for the management of patients with an intracranial aneurysm, with or without rupture.

    Congenital fibrosarcomas are malignant tumors that arise in soft tissues. In infants this unique tumor does not commonly metastasize, even though there may be local recurrences. We report here a boy who had congenital fibrosarcoma in his right foot, which was completely excised at the age of 3 days. Four months later, a solitary encapsulated metastasis emerged in thoracic chest wall, which was operated. During adjuvant chemotherapy he developed histologically confirmed fibrosarcoma metastases in the heart. After extended treatment with cyclophosphamide/topotecan and gemcitabine/docetaxel, the heart tumors disappeared and he has been in complete remission for 3 years.

    Full Text Available Objective To study the clinical, neuroimaging and histopathological features of intracranial germinoma.  Methods One case of intracranial germinoma with ventricular system dissemination was reported, and related literatures were reviewed.  Results A 34-year-old male complained of progressive dizziness for 30 d and manifested unsteady gait for 45 d. Radiological examinations revealed low signal intensity on T1WI and hyperintense on T2WI in the corpus callosum, left cerebellum, around the fourth ventricle, aqueduct mesencephalon, the ventral pons and pineal region, with even or uneven enhancement after contrast. The clinical initial diagnosis was "intracranial multiple focal lesions and high possibility of multiple sclerosis". After well response to glucocorticoid impact and dehydration, the patient stopped taking drugs but presented relapse and exacerbation. Later, he underwent biopsy on pineal region and was diagnosed as intracranial germinoma. Microscopically, the big germ cells and lymphocytes coexisted. Tumor cells were epithelioid cells with transparent cytoplasm, prominent nuclei and mitotic activity. Lymphocytes were distributed along interstitial substance of vessel and fiber, and individual syncytiotrophoblasts were sprasely distributed. Immunohistochemical staining showed tumor cells were positive for CD117 and OCT3/4, and the syncytiotrophoblasts were positive for β-human chorionic gonadotropin ( β-hCG. The clinical symptoms were completely alleviated after radiotherapy and chemotherapy.  Conclusions Because of the sensitivity for radiotherapy and chemotherapy, intracranial germinoma can be diagnosed and treated early to improve its prognosis. However, it is very easy to disseminate along with ventricular system and form multiple lesions, leading to atypical clinical and imaging manifestations, which is a big challenge for clinical diagnosis. doi: 10.3969/j.issn.1672-6731.2014.05.010

    Full Text Available ABSTRACT: Neurofibromatoses Type 1(NF 1 is an autosomal domin ant disease characterized by disordered growth of ectodermal tissues, and is part of a group of disorders called Phakomatoses (neurocutaneous syndrome. NF 1 (aka V on Recklinghausen's disease patients develop both benign and malignant tumors at an incre ased frequency. Malignant peripheral nerve sheath tumours (MPNST is a very rare tumor, with an incidence of 1 per 1,00,000 population. MPNSTs occur in about 2% to 5% of neurofi bromatosis patients and constitutes between 3 to 10% of all soft tissue sarcomas. Most MPNSTs are considered as high-grade sarcomas originating from tissues of mesenchymal or igin and are biologically aggressive tumours with notoriety for recurrence and metastase s. In this paper, we present a case of a 64 yr old male, who was diagnosed with NF 1 at the age of 25 yrs. He presented with a local recurrence of MPNST in left thigh, He was previously operated for MPNST (Stage 1 at the same site with a tumor free margin, 3 yrs back. Thereafter patient was disease free but two and half yrs later developed a swelling at the same site. Diagnostic core needle biopsy demonstrated a high g rade MPNST.

  2. Epidemiology and genetics of intracranial aneurysms. (United States)

    Caranci, F; Briganti, F; Cirillo, L; Leonardi, M; Muto, M


    Intracranial aneurysms are acquired lesions (5-10% of the population), a fraction of which rupture leading to subarachnoid hemorrhage with devastating consequences. Until now, the exact etiology of intracranial aneurysms formation remains unclear. The low incidence of subarachnoid hemorrhage in comparison with the prevalence of unruptured IAs suggests that the vast majority of intracranial aneurysms do not rupture and that identifying those at highest risk is important in defining the optimal management. The most important factors predicting rupture are aneurysm size and site. In addition to ambiental factors (smoking, excessive alcohol consumption and hypertension), epidemiological studies have demonstrated a familiar influence contributing to the pathogenesis of intracranial aneurysms, with increased frequency in first- and second-degree relatives of people with subarachnoid hemorrhage. In comparison to sporadic aneurysms, familial aneurysms tend to be larger, more often located at the middle cerebral artery, and more likely to be multiple. Other than familiar occurrence, there are several heritable conditions associated with intracranial aneurysm formation, including autosomal dominant polycystic kidney disease, neurofibromatosis type I, Marfan syndrome, multiple endocrine neoplasia type I, pseudoxanthoma elasticum, hereditary hemorrhagic telangiectasia, and Ehlers-Danlos syndrome type II and IV. The familial occurrence and the association with heritable conditions indicate that genetic factors may play a role in the development of intracranial aneurysms. Genome-wide linkage studies in families and sib pairs with intracranial aneurysms have identified several loci on chromosomes showing suggestive evidence of linkage, particularly on chromosomes 1p34.3-p36.13, 7q11, 19q13.3, and Xp22. For the loci on 1p34.3-p36.13 and 7q11, a moderate positive association with positional candidate genes has been demonstrated (perlecan gene, elastin gene, collagen type 1 A2 gene

The low incidence of subarachnoid hemorrhage in comparison with the prevalence of unruptured IAs suggests that the vast majority of intracranial aneurysms do not rupture and that identifying those at highest risk is important in defining the optimal management. The most important factors predicting rupture are aneurysm size and site. In addition to ambiental factors (smoking, excessive alcohol consumption and hypertension), epidemiological studies have demonstrated a familiar influence contributing to the pathogenesis of intracranial aneurysms, with increased frequency in first- and second-degree relatives of people with subarachnoid hemorrhage. In comparison to sporadic aneurysms, familial aneurysms tend to be larger, more often located at the middle cerebral artery, and more likely to be multiple. Other than familiar occurrence, there are several heritable conditions associated with intracranial aneurysm formation, including autosomal dominant polycystic kidney disease, neurofibromatosis type I, Marfan syndrome, multiple endocrine neoplasia type I, pseudoxanthoma elasticum, hereditary hemorrhagic telangiectasia, and Ehlers-Danlos syndrome type II and IV. The familial occurrence and the association with heritable conditions indicate that genetic factors may play a role in the development of intracranial aneurysms. Genome-wide linkage studies in families and sib pairs with intracranial aneurysms have identified several loci on chromosomes showing suggestive evidence of linkage, particularly on chromosomes 1p34.3–p36.13, 7q11, 19q13.3, and Xp22. For the loci on 1p34.3–p36.13 and 7q11, a moderate positive association with positional candidate genes has been demonstrated (perlecan gene, elastin gene, collagen type 1 A2

    Two cases of osteogenic sarcoma with skeletal muscle metastases are described. A 40-year-old woman presented with progressive swelling of both calves and a soft tissue back lump. She had been diagnosed with mandibular chondroblastic osteogenic sarcoma 6 years earlier. Radiographs showed calcified masses. MRI scans and bone scintigraphy revealed multiple soft tissue masses in both calves. Bone scintigraphy also showed uptake in the back lump, right thigh and left lung base. Biopsy confirmed metastatic chondroblastic osteogenic sarcoma, which initially responded well to chemotherapy. However, the metastatic disease subsequently progressed rapidly and she died 21 months after presentation. The second case concerns a 20-year-old man who presented with a pathologic fracture of the humerus, which was found to be due to osteoblastic osteogenic sarcoma. He developed cerebral metastases 17 months later, followed by metastases at other sites. Calcified masses were subsequently seen on radiographs of the abdomen and chest. CT scans confirmed the presence of densely calcified muscle metastases in the abdominal wall, erector spinae and gluteal muscles. The patient`s disease progressed rapidly and he died 30 months after presentation. (orig.) With 6 figs., 29 refs.

    The management of brainstem metastases is challenging. Surgical treatment is usually not an option, and chemotherapy is of limited utility. Stereotactic radiosurgery has emerged as a promising palliative treatment modality in these cases. The goal of this study is to assess our single institution experience treating brainstem metastases with Gamma Knife radiosurgery (GKRS). This retrospective chart review studied 41 patients with brainstem metastases treated with GKRS. The most common primary tumors were lung, breast, renal cell carcinoma, and melanoma. Median age at initial treatment was 59 years. Nineteen (46%) of the patients received whole brain radiation therapy (WBRT) prior to or concurrent with GKRS treatment. Thirty (73%) of the patients had a single brainstem metastasis. The average GKRS dose was 17 Gy. Post-GKRS overall survival at six months was 42%, at 12 months was 22%, and at 24 months was 13%. Local tumor control was achieved in 91% of patients, and there was one patient who had a fatal brain hemorrhage after treatment. Karnofsky performance score (KPS) >80 and the absence of prior WBRT were predictors for improved survival on multivariate analysis (HR 0.60 (p = 0.02), and HR 0.28 (p = 0.02), respectively). GKRS was an effective treatment for brainstem metastases, with excellent local tumor control. PMID:24886816

    Fahad Al-Lhedan


    Full Text Available Secondary osseous involvement in lymphoma is more common compared to primary bone lymphoma. The finding of osseous lesion can be incidentally discovered during the course of the disease. However, osseous metastases are infrequently silent. Detection of osseous metastases is crucial for accurate staging and optimal treatment planning of lymphoma. The aim of imaging is to identify the presence and extent of osseous disease and to assess for possible complications such as pathological fracture of the load-bearing bones and cord compression if the lesion is spinal. We are presenting two patients with treated lymphoma who were in complete remission. On routine follow-up contrast enhanced CT, there were new osteoblastic lesions in the spine worrisome for metastases. Additional studies were performed for further evaluation of both of them which did not demonstrate any corresponding suspicious osseous lesion. The patients have a prior history of chronic venous occlusive thrombosis that resulted in collaterals formation. Contrast enhancement of the vertebral body marrow secondary to collaterals formation and venous flow through the vertebral venous plexus can mimic the appearance of spinal osteoblastic metastases.

  11. Role of palliative radiotherapy in brain metastases

    Directory of Open Access Journals (Sweden)

    Ramesh S Bilimagga


    Full Text Available Background: Brain metastases are a common manifestation of systemic cancer and exceed primary brain tumors in number and are a significant cause of neurologic problems. They affect 20-40% of all cancer patients. Aggressive management of brain metastases is effective in both symptom palliation and prolonging the life. Radiotherapy has a major role to play in the management of brain metastases. AIM: The aim of the study was to know the outcome of palliative radiotherapy in symptomatic brain metastases in terms of improvement in their performance status. Materials and Methods: This is a retrospective study of 63 patients diagnosed to have brain metastases and treated with palliative whole brain radiotherapy to a dose of 30 Gy in 10 fractions over two weeks between June 1998 and June 2007. Diagnosis was done in most of the cases with computed tomography scan and in a few with magnetic resonance imaging. Improvement in presenting symptoms has been assessed in terms of improvement in their performance status by using the ECOG scale. Results: Fifty-four patients completed the planned treatment. Eight patients received concurrent Temozolamide; 88% of patients had symptom relief at one month follow-up; 39/54 patients had a follow-up of just one to three months. Hence survival could not be assessed in this study. Conclusion: External beam radiotherapy in the dose of 30 Gy over two weeks achieved good palliation in terms improvement in their performance status in 88% of patients. Addition of concurrent and adjuvant Timozolamide may improve the results.

  12. Zosteriform skin metastases: Clue to an undiagnosed breast cancer

    Directory of Open Access Journals (Sweden)

    Neha C Virmani


    Full Text Available Cancer metastases represent the most devastating aspect of malignancy, since the mortality of cancer patients is mainly related to the metastatic behavior of the primary neoplasm. Skin metastases are usually late events in the course of tumor progression. Excluding melanoma, the most common tumor to metastasize to the skin is breast cancer. Patients who develop cutaneous metastases rarely present with a zosteriform distribution. Herein, we present a 60-year-old female, an undiagnosed case of breast cancer, with zosteriform metastases along her right T2-T3 dermatome.

    The endovascular treatment of intracranial aneurysms 3 mm or less is considered controversial. The purpose of this study is to report angiographic and clinical results following coiling of such aneurysms and compare them to those of larger aneurysms (> 3 mm).Between November 1999 and November 2009...... endovascular treatment was attempted in 956 consecutive intracranial aneurysms. Of 956 aneurysms, 111 aneurysms were very small aneurysms with a maximal diameter of 3 mm or less. We conducted a retrospective analysis of angiographic and clinical outcome following coiling of very small aneurysms...... and subsequently comparing it to the results of larger aneurysms.Coiling initially failed in eight aneurysms. In the remaining 103 aneurysms endovascular treatment was accomplished and immediate angiographic results showed complete aneurysm occlusion in 43 aneurysms, nearly complete aneurysm occlusion in 54...

  16. A giant frontoethmoid mucocele with intracranial extension. (United States)

    Işık, Abdülcemal Ümit; Arslan, Selçuk; Arslan, Erhan; Baykal, Süleyman


    Mucoceles are mucus-containing cysts lined by epithelium. Although benign, they may show expansive growth and remain undiagnosed until symptoms due to compression of surrounding structures arise. We report a rare case of frontoethmoid mucocele with intracranial extension in an 80-year-old woman with complaints of headache, right diplopia and proptosis. A right frontoorbital craniotomy was performed, and a mucocele in the frontal sinus extending into the frontal lobe and orbit was totally removed. The patient was successfully treated without any complication. The two-year follow-up results were satisfactory. Magnetic resonance imaging excluded any recurrence of the mucocele. Combined intranasal and transcranial approach is necessary to treat giant frontoetmoid mucoceles with intracranial extension. © The Author(s) 2014 Reprints and permissions:

    The radiologist plays a crucial role in identifying and narrowing the differential diagnosis of intracranial infections. A thorough understanding of the intracranial compartment anatomy and characteristic imaging findings of specific pathogens, as well incorporation of the clinical information, is essential to establish correct diagnosis. Specific types of infections have certain propensities for different anatomical regions within the brain. In addition, the imaging findings must be placed in the context of the clinical setting, particularly in immunocompromised and human immunodeficiency virus (HIV)-positive patients. This paper describes and depicts infections within the different compartments of the brain. Pathology-proven infectious cases are presented in both immunocompetent and immunocompromised patients, with a discussion of the characteristic findings of each pathogen. Magnetic resonance spectroscopy (MRS) characteristics for several infections are also discussed.

  18. Intracranial neurenteric cyst traversing the brainstem

    Directory of Open Access Journals (Sweden)

    Jasmit Singh


    Full Text Available Neurenteric cysts (NECs, also called enterogenous cysts, are rare benign endodermal lesions of the central nervous system that probably result from separation failure of the notochord and upper gastrointestinal tract. Most frequently they are found in the lower cervical spine or the upper thoracic spine. Intracranial occurrence is rare and mostly confined to infratentorial compartment, in prepontine region [51%]. Other common locations are fourth ventricle and cerebellopontine angle. There are few reports of NEC in medulla or the cerebellum. Because of the rarity of the disease and common radiological findings, they are misinterpreted as arachnoid or simple cysts until the histopathological confirmation, unless suspected preoperatively. We herein report a rare yet interesting case of intracranial NEC traversing across the brainstem.

  19. The contemporary management of intracranial atherosclerotic disease. (United States)

    Leng, Xinyi; Wong, Ka Sing; Leung, Thomas W


    Intracranial atherosclerotic disease is the most common cause of cerebral vasculopathy and an important stroke etiology worldwide, with a higher prevalence in Asian, Hispanic and African ethnicities. Symptomatic intracranial atherosclerotic disease portends a recurrent stroke risk as high as 18% at one year. The key to secondary prevention is an understanding of the underlying stroke mechanism and aggressive control of conventional cardiovascular risks. Contemporary treatment includes antiplatelet therapy, optimal glycemic and blood pressure control, statin therapy and lifestyle modifications. For patients with high-grade (70-99%) symptomatic steno-occlusion, short-term dual antiplatelet therapy with aspirin and clopidogrel followed by life-long single antiplatelet therapy may reduce the recurrent risk. Current evidence does not advocate percutaneous transluminal angioplasty and stenting as an initial treatment. External counterpulsation, encephaloduroarteriosynangiosis and remote limb ischemic preconditioning are treatments under investigation. Future studies should aim at predicting patients prone to recurrence despite of medical therapies and testing the efficacy of emerging therapies.

    Andrew Conger; Charles Kulwin; Lawton, Michael T; Cohen-Gadol, Aaron A.


    Background: Ideal management of intracranial arteriovenous malformations (AVMs) remains poorly defined. Decisions regarding management of AVMs are based on the expected natural history of the lesion and risk prediction for peritreatment morbidity. Microsurgical resection, stereotactic radiosurgery, and endovascular embolization alone or in combination are all viable treatment options, each with different risks. The authors attempt to clarify the existing literature′s understanding of the natu...

  2. Diagnosis and treatment of intracranial immature teratoma. (United States)

    Huang, Xiang; Zhang, Rong; Zhou, Liang-Fu


    The purpose of this paper is toexplore the clinical features, treatment and prognosis of intracranial immature teratomas. The clinical data, serum levels of tumor markers, treatment regimens and prognosis of 15 patients with intracranial immature teratomas were reviewed retrospectively. In patients whose plasma alpha-fetoprotein (AFP) and beta-human chorionic gonadotropin (beta-HCG) were determined, AFP and beta-HCG were elevated in 57.1 and 16.7% of the cases, respectively. All patients received surgical treatment. The tumor was totally removed in 12 cases, subtotally in 2, and partially in 1 case. After surgery, of the 15 patients, 9 received radiotherapy, 4 gamma knife surgery and 7 chemotherapy. Thirteen patients were followed up. Compared to the common 5-year survival rate of 40%, in patients who received gamma knife surgery, the 5-year survival rate after surgery was 100%, which is better than the 5-year survival rate of patients who did not receive gamma knife surgery (p = 0.0049). Postoperative radiotherapy and chemical therapy had no significant impact on the 5-year survival rate (p > 0.05). The prognosis of intracranial immature teratomas is poor. The detection of their clinical manifestation, the analysis of imaging features and the serum levels of tumor markers are helpful in diagnosing intracranial teratomas. The total removal of the tumor is important to cure the disease. We did not see a difference in outcome between patients who received postoperative chemotherapy or radiotherapy and those who did not. Regular follow-up MRI examinations are necessary so that the conditions of the patients can be closely monitored. If a patient has residual or recurrent tumor after surgery, gamma knife surgery can be effective. Copyright 2009 S. Karger AG, Basel.

    Conill, C; Jorcano, S; Planas, I; Marruecos, J; Casas, F; Fontenla, J R


    Choroidal metastases from lung cancer can be the initial clinical manifestation of metastasic disease, although they generally coexist with at least two more metastasic sites. The most common symptom is decreased vision, however 20% of brain metastases can present with visual alterations. A differential diagnosis within brain metastases and/or choroidal is necessary. We present the case of a patient with lung cancer and decreased vision who was diagnosed as simultaneous choroidal and brain metastases. Radiation therapy (20Gy/5fractions) significantly improves decreased vision. This case shows that, although life expectancy of patients with metastasic lung cancer is short, an adequate diagnosis and treatment, can improve the quality of life of those patients.

    Intracranial lipomas are very rare and reports of infantile lipomas are scarce. Nine cases of intracranial lipomas, five in infants and four in adults are described and characteristic findings of the CT are presented. Two of the six cases involved lipomas at the corpus callosum that were associated with frontal dysraphism and cranium bifidum at the midline of frontal region. Five of the nine cases involved lipomas at the quadrigeminal cistern. In one case with an advanced enlargement in circumference of the head in the perinatal period, a V-P shunt was conducted for obstructive hydrocephalus. Another case had widely ranging agenesis of the corpus callosum associated with an interhemispheric cyst showing the right sided parietal and occipital lobes through the callosal agenesis. One of the nine cases had a lipoma in the left sylvian fissure and in the adult was in the interpeduncular cistern. Four of the nine cases were associated with agenesis of the corpus callosum. Based on these cases and published reports, the CT features of intracranial lipoma are discussed.

    Traver, William J.


    This slide presentation is an overview of the some of the known results of spaceflight induced intracranial hypertension. Historical information from Gemini 5, Apollo, and the space shuttle programs indicated that some vision impairment was reported and a comparison between these historical missions and present missions is included. Optic Disc Edema, Globe Flattening, Choroidal Folds, Hyperopic Shifts and Raised Intracranial Pressure has occurred in Astronauts During and After Long Duration Space Flight. Views illustrate the occurrence of Optic Disc Edema, Globe Flattening, and Choroidal Folds. There are views of the Arachnoid Granulations and Venous return, and the question of spinal or venous compliance issues is discussed. The question of increased blood flow and its relation to increased Cerebrospinal fluid (CSF) is raised. Most observed on-orbit papilledema does not progress, and this might be a function of plateau homeostasis for the higher level of intracranial pressure. There are seven cases of astronauts experiencing in flight and post flight symptoms, which are summarized and follow-up is reviewed along with a comparison of the treatment options. The question is "is there other involvement besides vision," and other Clinical implications are raised,

    Background Olfactory neuroblastoma (ONB) is a rare tumor that often arise from the nasal cavity. The aim of this study was to investigate the clinical characteristics and treatments of intracranial invasive ONB.Methods Between July 2001 and August 2005, 5 patients with intracranial invasive ONB were treated in our department. Their clinical features, radiological and pathological characteristics, and surgical treatments were analyzed.Among the 5 patients, 1 received transnasal biopsy, and 4 were operated through the transfrontal or extended bifrontal approaches to reconstruct the skull base. After the operation, all the patients received radiotherapy, and one received chemotherapy. They were followed up for 6 to 45 months.Results The ONB was resected totally in the 4 patients. In all the patients, nasal obstruction was alleviated without cerebrospinal fluid leakage. The visual acuity was improved in 3 patients, who had a decreased visual acuity before the operation. Two patients had metastasis into the lumbosacral spinal canal 6 and 8 months after the operation, one of them received a second operation and the other died.Concluslon ONB has no specific symptoms. Intracranial ONB should be resected as far as possible, and treated by radiotherapy afterthe operation.

    The purpose of this study is to report the characteristics and outcomes of pediatric patients with intracranial aneurysms. From 1998 to 2005, 25 pediatric patients (aged {<=}17 years) with intracranial aneurysm were treated at our institute. Eleven of 25 patients had subarachnoid hemorrhage. In ten patients, the aneurysm was an incidental finding. One patient presented with cranial nerves dysfunction and three with neurological deficits. The locations of the aneurysms were as follows: vertebral artery (VA; n = 9), middle cerebral artery (MCA; n = 5), posterior cerebral artery (PCA; n = 4), basilar artery (BA; n = 2), anterior communicating artery (n = 2), anterior cerebral artery (n = 2), and internal carotid artery (n = 1). Five patients were treated with selective embolization with coils. Sixteen patients were treated with parent vessel occlusion (PVO). Eight PVOs were performed with balloons and eight were performed with coils. One patient with a VA aneurysm was spontaneously thrombosed 4 days after the initial diagnostic angiogram. In three patients treated with stent alone or stent-assisted coiling, one with BA trunk aneurysm died. One aneurismal recurrence occurred and was retreated. At a mean follow-up duration of 23.5 months, 96% of patients had a Glasgow Outcome Scale score of 4 or 5. Pediatric intracranial aneurysms occur more commonly in male patients and have a predilection for the VA, PCA, and MCA. PVO is an effective and safe treatment for fusiform aneurysms. Basilar trunk fusiform aneurysms were difficult to treat and were associated with a high mortality rate. (orig.)

    Full Text Available Cerebral metastases occur with 10 to 30 % of all oncological patients. Hemorrhages into cerebral metastases are one of the most dangerous complications of the metastatic process. With that, cerebral metastases of such widespread solid malignant tumors as melanoma, kidney cancer, germ cell tumors, less frequently, lung cancer and breast cancer are prone to hemorrhages. The purpose of the work is to improve the results of surgical treatment of patients with brain metastases complicated with hemorrhages.Materials  and  methods. Surgical  treatment  of  69  patients  with  brain  metastases complicated  with  hemorrhages was  performed in N.N. Blokhin Russian Cancer Research Center. Hemorrhage on the macroscopic level was confirmed intraoperatively and in accordance with the results of the morphological study of surgical drugs. Total microsurgical resection of one or several cerebral metastases with hemor rhages was performed regarding all patients studied. The time interval of observation of patients after the surgical treatment comprises 1 to 72 months. There were 27 women and 42 men. The age range was from 18 to 74 y.o. Besides, the state of veins of lower extremities and the state of the coagulation blood system in accordance with the data of coagulograms was studies. The analysis of the macrostructure and the microstructure of metastases with hemorrhages as well as the morphological study of the brain tissue adjacent to hematomas was performed with a morphological study and histological techniques.

    Hippocampal-avoidance whole brain radiotherapy (HA-WBRT) for multiple brain metastases may prevent treatment-related cognitive decline, compared to standard WBRT. Additionally, simultaneous integrated boost (SIB) on individual metastases may further improve the outcome. Here, we present initial data concerning local tumour control (LTC), intracranial progression-free survival (PFS), overall survival (OS), toxicity and safety for this new irradiation technique. Twenty patients, enrolled between 2011 and 2013, were treated with HA-WBRT (30 Gy in 12 fractions, D{sub 98} {sub %} to hippocampus ≤ 9 Gy) and a SIB (51 Gy) on multiple (2-13) metastases using a volumetric modulated arc therapy (VMAT) approach based on 2-4 arcs. Metastases were evaluated bidimensionally along the two largest diameters in contrast-enhanced three-dimensional T1-weighed MRI. Median follow-up was 40 weeks. The median time to progression of boosted metastases has not been reached yet, corresponding to a LTC rate of 73 %. Median intracranial PFS was 40 weeks, corresponding to a 1-year PFS of 45.3 %. Median OS was 71.5 weeks, corresponding to a 1-year OS of 60 %. No obvious acute or late toxicities grade > 2 (NCI CTCAE v4.03) were observed. D{sub mean} to the bilateral hippocampi was 6.585 Gy ± 0.847 (α/β = 2 Gy). Two patients developed a new metastasis in the area of hippocampal avoidance. HA-WBRT (simultaneous integrated protection, SIP) with SIB to metastases is a safe and tolerable regime that shows favorable LTC for patients with multiple brain metastases, while it has the potential to minimize the side-effect of cognitive deterioration.

    Purpose: This is the first Brazilian study intended to evaluate the response of pain relief with radiotherapy in three different fractionation and the clinical differences in managing pain in patients with painful bone metastases. Methods: Prospective study of patients with painful bone metastases referred to the Radiotherapy Sector of the Hospital de Cancer de Barretos for pain-relieving radiotherapy between March and December 2010. It is known that radiotherapy seems to alter the activation of osteoclast-mediated bone resorption, relieving pain in cases of painful bone metastases. Patients were assessed in relation to the status of pain intensity before and after the initiation of radiotherapy. Either a single fraction of 8Gy, five fractions of 4Gy or ten fractions of 3Gy were given. A visual analog scale (VAS) was applied by doctors, nurses and nursing technicians to assess pain intensity at each session of radiotherapy, and follow-up at 8, 30 and 90 days from the end of treatment. Results: We evaluated 92 consecutive patients, 48 male and 44 female, with a median age of 58 years. We found that 14% of patients referred from the Palliative Care or Clinical Oncology sectors need better pharmacological analgesia due to severe pain, compared with 40.5% of patients from the other sectors (p = 0.004). We also found that the onset of pain relief to patients receiving 10 fractions of 300cGy analgesia without changing the pre-radiotherapy analgesia occurred with significance after the fifth fraction. Improvement in pain experienced within 90 days of follow-up was found in eighty percent of patients, independent of fractionated radiotherapy, site of metastases and the clinical condition of the patient. Discussion/Conclusion: The Palliative Care and Clinical Oncology sectors expressed greater concern in regards to analgesia for the patient with painful bone metastases. Radiotherapy is an effective pain-relieving treatment in different fractionation studied, even though the

    Piantino, Juan A; Goldenberg, Fernando D; Pytel, Peter; Wagner-Weiner, Linda; Ansari, Sameer A


    In the pediatric population, intracranial fusiform aneurysms have been associated with human immunodeficiency virus/acquired immunodeficiency syndrome and rarely with opportunistic infections related to other immunodeficiencies. The HIV virus and other infectious organisms have been implicated in the pathophysiology of these aneurysms. We present a child with T-cell immunodeficiency but no evidence of human immunodeficiency virus or opportunistic intracranial infections that developed progressive bilateral fusiform intracranial aneurysms. Our findings suggest a role of immunodeficiency or inflammation in the formation of some intracranial aneurysms.

    Rovegno, Maximiliano; Valenzuela, José Luis; Mellado, Patricio; Andresen, Max


    The use of hypothermia after cardiac arrest caused by ventricular fibrillation is a standard clinical practice, however its use for neuroprotection has been extended to other conditions. We report a 23-year-old male with intracranial hypertension secondary to a parenchymal hematoma associated to acute hydrocephalus. An arterial malformation was found and embolized. Due to persistent intracranial hypertension, moderate hypothermia with a target temperature of 33°C was started. After 12 hours of hypothermia, intracranial pressure was controlled. After 13 days of hypothermia a definitive control of intracranial pressure was achieved. The patient was discharged 40 days after admission, remains with a mild hemiparesia and is reassuming his university studies.

    Cancer invasion and metastases is a complex multistep process. In order for a tumor cell to successfully traverse all the steps of this process and initiate a metastatic colony, it must express the right combination of gene products. Such gene products may include proteins which regulate cell...... interaction with the basement membrane and cell motility. Tumor cells attach to the basement membrane glycoprotein laminin via the cell surface laminin receptor. The human laminin receptor was purified and molecularly cloned. The level of laminin receptor mRNA is a variety of human carcinoma cells correlated...... with the number of laminin receptors on the cell surface of these cells. Following attachment to the basement membrane, the tumor cell next secretes proteases which may degrade type IV collagen.

    Dobrowsky, W; Schmid, A P; Dobrowsky, E


    From 1975 to 1984, thirteen patients were submitted to radiotherapy for choroid metastases of mammary carcinoma. Bilateral manifestation was found in three cases, thus sixteen eyes have been treated. All irradiations were performed with high voltage equipment. The posterior section of the eye was irradiated with 25 to 50 Gy over 2.5 to 5 weeks. Complete regression was achieved in nine out of sixteen cases, five patients showed an improvement of at least 50%, no considerable effect was found in two cases. The survival is 4 to 48 months (median survival 20 months) from the beginning of radiotherapy. Radiotherapy is a quick, efficient, and sparing treatment in choroid metastases. If applied in due time, it can prevent a visual disorder or amaurosis, thus improving the patients' quality of life.

    Full Text Available BackgroundThe objective of this study was to report our institutional experience with Gamma Knife® Radiosurgery (GKRS in the treatment of patients with brain metastases.MethodsRetrospectively collected demographic and clinical data on 126 patients with intracranial metastases were reviewed. The patients in our study underwent GKRS at Vidant Medical Center between 2009 and 2014. Kaplan–Meier curves were used to compare survival based on clinical characteristics for univariate analysis, and a Cox proportional hazards model was used for multivariate analysis.ResultsThe median age of the patient population was 62 years. Medicare patients constituted 51% of our patient cohort and Medicaid patients 15%. The most common tumor histologies were non-small cell lung cancer (50%, breast cancer (12.7%, and melanoma (11.9%. The median overall survival time for all patients was 5.8 months. Patients with breast cancer had the longest median survival time of 9.15 months, while patients with melanoma had the shortest median survival time of 2.86 months. On univariate analysis, the following factors were predictors for improved overall survival, ECOG score 0 or 1 vs. 2 or greater (17.0 vs. 1.8 months, p < 0.001, controlled extracranial disease vs. progressive extracranial disease (17.4 vs. 4.6 months, p = 0.0001, recursive partitioning analysis Stage I vs. II–III (18.2 vs. 6.2 months, p < 0.007, multiple GKRS treatments (p = 0.002, prior brain metastasectomy (p = 0.012, and prior chemotherapy (p = 0.021. Age, ethnicity, gender, previous external beam radiation therapy, number of brain metastases, and hemorrhagic vs. non-hemorrhagic tumors were not predictors of longer median survival time. Number of metastatic brain lesions of 1–3 vs. ≥4 (p = 0.051 and insurance status of Medicare/Medicaid vs. commercial insurance approached significance (13.7 vs. 6.8 months, p = 0.08.

    Berber, Eren; Flesher, Nora; Siperstein, Allan E


    We previously reported on the safety and efficacy of laparoscopic radiofrequency thermal ablation (RFA) for treating hepatic neuroendocrine metastases. The aim of this study is to report our 5-year RFA experience in the treatment of these challenging group of patients. Of the 222 patients with 803 liver primary and secondary tumors undergoing laparoscopic RFA between January 1996 and August 2001, a total of 34 patients with 234 tumors had neuroendocrine liver metastases. There were 25 men and 9 women with a mean +/- SEM age of 52 +/- 2 years who underwent 42 ablations. Primary tumor types included carcinoid tumor in 18 patients, medullary thyroid cancer in 7, secreting islet cell tumor in 5, and nonsecreting islet cell tumor in 4. There was no mortality, and the morbidity was 5%. The mean hospital stay was 1.1 days. Symptoms were ameliorated in 95%, with significant or complete symptom control in 80% of the patients for a mean of 10+ months (range 6-24 months). All patients were followed for a mean +/- SEM of 1.6 +/- 0.2 years (range 1.0-5.4 years). During this period new liver lesions developed in 28% of patients, new extrahepatic disease in 25%, and local liver recurrence in 13%; existing liver lesions progressed in 13%. Overall 41% of patients showed no progression of their cancer. Nine patients (27%) died. Mean +/- SEM survivals after diagnosis of primary disease, detection of liver metastases, and performance of RFA were 5.5 +/- 0.8 years, 3.0 +/- 0.3 years, and 1.6 +/- 0.2 years, respectively. Sixty-five percent of the patients demonstrated a partial or significant decrease in their tumor markers during follow-up. In conclusion, RFA provides excellent local tumor control with overnight hospitalization and low morbidity in the treatment of liver metastases from neuroendocrine tumors. It is a useful modality in the management of these challenging group of patients.

    Forty-one patients suffered initial relapses with brain metastasis after surgery for non-small lung cancer at our hospital between 1978 and 1995. These patients were a total of 8.4% of all cases of surgical removal, and had an average relapse period of 8.6 months {+-} 8.0 months after surgery on the primary lesions. Of these, surgical removal of metastasized lesions was performed on 18 patients (43%), in which the 5-year post-operative survival rate was 35.7%, and the median survival time was good at 28 months. It was found that the survival period was significantly extended in the group whose relapse period was less than one year after surgery on the primary lesions, and in the group who received cranial irradiation post-operatively on the metastasized brain lesion. Following surgery on the metastasized lesion, second relapses occurred in nine patients, and six patients suffered from second relapses in the brain, of which four did not receive cranial irradiation post-operatively. Cases of radiotherapy in patients of 70 years of age or more frequently manifested post-radiotherapy subacute neuropathy. From the above, it is thought that the following procedures should be adopted: Periodic examination for brain metastasis during the 24 months following surgery for non-small cell lung carcinoma for purposes of early detection; in cases where brain metastasis is detected, if no metastasis is identified in other organs, a policy of surgical removal should be adopted where possible; and, in cases of 70 years of age or less following surgery on the metastasized lesion, cranial irradiation should be considered.

    The presence of distant metastases from differentiated thyroid carcinoma decreases the 10-year survival of patients by 50%. Bone metastases represent a frequent complication especially of follicular thyroid cancer and severely reduce the quality of life causing pain, fractures, and spinal cord compression. Diagnosis is established by correlating clinical suspicion with imaging. Imaging is essential to detect, localize, and assess the extension of the lesions and should be used in conjunction with clinical evidence. Bone metastases are typically associated with elevated markers of bone turnover, but these markers have not been evaluated in differentiated thyroid cancer. Skeletal and whole-body magnetic resonance imaging and fusion 2-deoxy-2-[18F]fluoro-D-glucose whole-body positron emission tomography/computed tomography (PET/CT) are the best anatomic and functional imaging techniques available in specialized centers. For well-differentiated lesions, iodine-PET scan combined (124)I-PET/CT is the newest imaging development and (131)I is the first line of treatment. Bisphosphonates reduce the complications rate and pain, alone or in combination with radioiodine, radionuclides, or external beam radiotherapy and should be employed. Surgery and novel minimally invasive consolidation techniques demand an appropriate patient selection for best results on a multimodal approach. Basic research on interactions between tumor cells and bone microenvironment are identifying potential novel targets for future more effective therapeutic interventions for less differentiated tumors.

  6. Pancreatic neuroendocrine tumor accompanied with multiple liver metastases

    Tomohide; Hori; Kyoichi; Takaori; Shinji; Uemoto


    Pancreatic neuroendocrine tumor(P-NET) is rare and slow-growing. Current classifications predict its progno-sis and postoperative recurrence. Curative resection is ideal, although often difficult, because over 80% of pa-tients have unresectable multiple liver metastases and extrahepatic metastasis. Aggressive surgery for liver metastases is important to improve survival. Aggressive or cytoreductive surgery for liver metastases is indi-cated to reduce hormone levels and improve symptoms and prognosis. Liver transplantation was originally con-ceived as an ideal therapy for unresectable liver metas-tases. Unfortunately, there is no clear consensus on the role and timing of surgery for primary tumor and liver metastases. Surgeons still face questions in deciding the best surgical scenario in patients with P-NET with unresectable liver metastases.

    Chordoma is a locally invasive tumor of low metastatic potential. Only six cases of chordoma that metastasized to the brain are found in the English literature. Most of these lesions were clinically silent and all were associated with extraneural metastases. The authors report a case of symptomatic brain metastasis from a sacrococcygeal chordoma in the absence of other metastases. The incidence, sites, and factors predictive of chordoma metastasis are discussed.

  8. Intracranial germ cell tumor mimicking anorexia nervosa. (United States)

    Andreu Martínez, F J; Martínez Mateu, J M


    We report on a case of a 23 year-old female diagnosed as having a germ-cell tumour located in the sellar region. The patient referred anorexia, psychic disorders, weight loss of 15 kilograms and secondary amenorrhea during the previous three years. This is the reason why the patient was diagnosed as having anorexia nervosa. Subsequently, the patient presented some endocrine dysfunction. MRI revealed the existence of a lesion located in suprasellar and hypothalamic regions. This case shows that the presence of intracranial tumours next to the hypothalamus must be borne in mind as a rare but real possibility in cases of anorexia nervosa, specially in those non-typical cases.

    Intracranial blister aneurysms are difficult to treat cerebrovascular lesions that typically affect the anterior circulation. These rare aneurysms can lead to acute rupture which usually cannot be treated via endovascular methods, but still require urgent surgical intervention. Surgical options are limited given their unique pathology and often require a combination of wrapping and clip reconstruction. In this video we present two patients with acute subarachnoid hemorrhage secondary to ruptured blister aneurysms. We demonstrate several surgical techniques for repairing the vascular defect with and without intraoperative rupture. The video can be found here:

    Bulens, C; Meerwaldt, J D; Koudstaal, P J; Van der Wildt, G J


    Spatial Contrast Sensitivity (CS) was studied in 20 patients with benign intracranial hypertension (BIH). At presentation CS loss was found in 43% of the eyes, and impairment of visual acuity attributed to BIH in only 16%. Nine patients had blurred vision or visual obscurations, all of whom had abnormal CS. The clinical application of CS measurement in BIH for monitoring the progression or regression of the disease is illustrated by serial measurements in 11 patients. Progressive visual loss in longstanding papilloedema and improvement of visual function in subsiding papilloedema can occur without any change in Snellen acuity or visual field charting.

    Extramedullary hematopoiesis (EMH) represents tumor-like proliferation of hemopoietic tissue which complicates chronic hemoglobinopathy. Intracranial EMH is an extremely rare occurrence. Magnetic resonance imaging (MRI) offers a precise diagnosis. It is essential to distinguish EMH from other extradural central nervous system tumors, because treatment and prognosis are totally different. Herein, we report the imaging findings of beta-thalassemia in a 13-year-old boy complaining of weakness of left side of the body and gait disturbance; CT and MRI revealed an extradural mass in the right temporoparietal region.

    Cebral, Juan R.; Hernandez, Monica; Frangi, Alejandro; Putman, Christopher; Pergolizzi, Richard; Burgess, James


    Characterization of the blood flow patterns in cerebral aneurysms is important to explore possible correlations between the hemodynamics conditions and the morphology, location, type and risk of rupture of intracranial aneurysms. For this purpose, realistic patient-specific models are constructed from computed tomography angiography and 3D rotational angiography image data. Visualizations of the distribution of hemodynamics forces on the aneurysm walls as well as the intra-aneurysmal flow patterns are presented for a number of cerebral aneurysms of different sizes, types and locations. The numerical models indicate that there are different classes of intra-aneurysmal flow patterns, that may carry different risks of rupture.

    Full Text Available We describe a case of intracranial malignant fibrous histiocytoma which had infiltrated pons, cerebellum and basal surface of left temporal lobe without any visible mass. The patient presented with a sudden loss of consciousness and vomiting. Clinical findings, laboratory tests, imaging and examination of the cerebrospinal fluid tended to establish the diagnosis of an infectious condition than a malignancy. Without any response to the antibiotics and with a progressive deterioration of neurologic and mental condition, the patient died after 20 days. In the autopsy, histological and immunohistochemical study of the brain revealed the diagnosis of malignant fibrous histiocytoma (MFH.

    We report a case of encephalopathy with paranoid psychosis in association with intracranial hypertension. This occurred in a patient whose diet consisted almost solely of walnuts, ginseng tea, and vitamin A supplements. The patient was found to be severely iron- and vitamin B12-deficient. She was vitamin A toxic. Venous sinus thrombosis was also present. Symptoms remitted with serial lumbar punctures, normalization of diet, and repletion of vitamin B12 and iron stores. Physicians should be alerted to the possibility of a potentially confusing clinical presentation with coexistent and seemingly mutually exclusive neurologic conditions in patients with extremely restricted or fad diets.

    Habib Rehman Khan


    Full Text Available Benign intracranial hypertension is characterized with increase in CSF opening pressure with no specific etiology. It is predominantly found in women of child bearing age and particularly in individuals with obesity. Visual disturbances or loss and associated headaches are common and can lead to blindness if left untreated. Diagnosis can be achieved once other causes of visual loss, headaches and high opening pressures are excluded. Management consists of serial optic disc assessments although no specific treatment is available despite recent trials using carbonic anhydrase inhibitors. Diet modification and weight management can help in therapy.

  18. The Intracranial Volume Pressure Response in Increased Intracranial Pressure Patients: Clinical Significance of the Volume Pressure Indicator (United States)


    Background For patients suffering from primary brain injury, monitoring intracranial pressure alone is not enough to reflect the dynamic intracranial condition. In our previous study, a segment of the pressure-volume curve can be expressed by the parabolic regression model with single indicator “a”. The aim of this study is to evaluate if the indicator “a” can reflect intracranial conditions. Methods Patients with traumatic brain injury, spontaneous intracranial hemorrhage, and/or hydrocephalus who had external ventricular drainage from January 2009 to February 2010 were included. The successive volume pressure response values were obtained by successive drainage of cerebral spinal fluid from intracranial pressure 20–25 mm Hg to 10 mm Hg. The relationship between withdrawn cerebral spinal fluid volume and intracranial pressure was analyzed by the parabolic regression model with single parameter “a”. Results The overall mean for indicator “a” was 0.422 ± 0.046. The mean of “a” in hydrocephalus was 0.173 ± 0.024 and in severe intracranial mass with slender ventricle, it was 0.663 ± 0.062. The two extreme intracranial conditions had a statistical significant difference (phydrocephalus. Brain computed tomography should be performed early if a rapid elevation of indicator “a” is detected, as it can reveal some ongoing intracranial pathology prior to clinical deterioration. Increased intracranial pressure was frequently observed in patients with intracranial pathology. The progression can be differentiated using the pattern of the volume pressure indicator.

  7. Management of breast cancer brain metastases: A practical review. (United States)

    Phillips, Claire; Jeffree, Rosalind; Khasraw, Mustafa


    Brain metastases are a common, and frequently challenging, clinical problem in the contemporary management of metastatic breast cancer. While the management of extracranial metastatic breast cancer is now strongly defined by tumour phenotype, this approach is not so well defined for brain metastases. We review available evidence regarding management of brain metastases, including the limited breast-cancer-specific data. A framework for management according to breast cancer phenotype is proposed.

    A whole-body mathematical model (10) for simulating intracranial pressure dynamics. In one embodiment, model (10) includes 17 interacting compartments, of which nine lie entirely outside of intracranial vault (14). Compartments (F) and (T) are defined to distinguish ventricular from extraventricular CSF. The vasculature of the intracranial system within cranial vault (14) is also subdivided into five compartments (A, C, P, V, and S, respectively) representing the intracranial arteries, capillaries, choroid plexus, veins, and venous sinus. The body's extracranial systemic vasculature is divided into six compartments (I, J, O, Z, D, and X, respectively) representing the arteries, capillaries, and veins of the central body and the lower body. Compartments (G) and (B) include tissue and the associated interstitial fluid in the intracranial and lower regions. Compartment (Y) is a composite involving the tissues, organs, and pulmonary circulation of the central body and compartment (M) represents the external environment.

    The charts of 176 previously untreated patients with head and neck squamous cell carcinoma who completed treatment during 2006 in Oro-Maxillo-Facial Clinic, UMF "Carol Davila" Bucharest were reviewed. These patients had no evidence of distant metastases when initially evaluated. The overall incidence of distant metastases was 27.84%, varying from 10.52% for buccal mucosa to 63.63% for tongue and floor of the mouth (p < 0.05). 80% of the metastases were detected within two years after treatment. The rate also increased with the T and N classification; however, the N stage had greater influence on the rate of metastases than the T stage.

    BACKGROUND: The design of melanoma sentinel lymph node (SLN) histologic protocols is based on the premise that most metastases are found in the central parts of the nodes, but the evidence for this belief has never been thoroughly tested. METHODS: The nodal location of melanoma metastases in 149...... were 77%, 79%, and 78%, respectively. No difference in either the mean volume or the maximum diameter of the metastases located exclusively outside the central and the peripheral protocols was found (volume: 0.036 vs. 0.031 mm and diameter: 0.320 vs. 0.332 mm). CONCLUSIONS: In SLNs, melanoma metastases...

    Full Text Available Bénédicte L'Heureux-Lebeau,1 Issam Saliba2 1University of Montreal, 2Department of Otolaryngology Head and Neck Surgery, Montreal University Hospital Center (CHUM, University of Montreal, Montreal, Quebec, Canada Background: Malignant peripheral nerve sheath tumors (MPNSTs are rare entities and MPNSTs of intracranial nerves are even more sporadic. MPNSTs present diagnosis and treatment challenges since there are no defined diagnosis criteria and no established therapeutic strategies. Methods: We reviewed literature for MPNST-related articles. We found 45 relevant studies in which 60 cases were described. Results: We identified 60 cases of intracranial nerve MPNSTs. The age ranged from 3 to 75 years old. Male to female ratio was 1.5:1. The most involved cranial nerves (CNs were CN VIII (60%, CN V (27%, and CN VII (10%. Most of the MPNSTs reported (47% arose sporadically, 40% arose from a schwannoma, 8% arose from a neurofibroma, and 6% arose from an unspecified nerve tumor. Twenty patients had a history of radiation exposure, four patients had neurofibromatosis type 1 (NF1, four patients had neurofibromatosis type 2 (NF2, and NF2 was suspected in two other patients. Twenty-two patients were treated with radiotherapy and presented a higher survival rate. Seventy-two percent of patients died of their disease while 28% of patients survived. One-year survival rate was 33%. Forty-five percent of tumors recurred and 19% of patients had metastases. Conclusion: MPNSTs involving CNs are very rare. Diagnosis is made in regards to the histological and pathological findings. Imaging may help orient the diagnosis. A preexisting knowledge of the clinical situation is more likely to lead to a correct diagnosis. The mainstay of treatment is radical surgical resection with adjuvant radiotherapy. Since these tumors are associated with a poor prognosis, a close follow-up is mandatory. Keywords: malignant peripheral nerve sheath tumor, MPNST, neurofibroma

    25 cases of clinically proved intracranial tuberculosis were studied by CT in the Hanyang Hospital from Feb. 1979 to July 1981. The medical records and CT films were reviewed. The results were as follows; 1. The age distribution was broad from 8 months to 43 years old. The incidence was higher in the age group from 0 to 5 years old. The male to female ratio was 1.8 : 1. 2. Clinical symptoms and signs revealed headache, nausea and vomiting, neck stiffness, positive Kernig's sign, and paralysis of the extremities. 3. At the time of CT examination 8 out of 25 cases were conscious, stuporous in 14 and unconscious in 3. 4. In CT, total or partial obliterations of the basal cisterns were observed in 21 out of 25 cases. 5. Intense abnormal contrast enhancement of the basal cistern were observed in 9 out of 25 cases. 6. Tuberculoma was found in 3 cases. Among these 3 cases had multiple tuberculomas and 1 case had single tuberculoma. 7. Moderate to marked dilatation of both lateral ventricles were observed in 21 cases. The 3rd and 4th ventricles were also dilated in 19 and 12 cases respectively. 8. 2 cases of cerebral infarction were observed, all in the bilateral basal gangilas. 9. Intracranial calcifications were observed in 2 cases who had histories of tuberculous meningitis, 4 to 9 years prior to CT examinations. The calcifications were multiple and located in the suprasellar areas.

    Objective: To study the neuroimaging features of intracranial solitary fibrous tumors (ISFTs). Materials and methods: Retrospective study of neuroimaging features of 9 consecutive histopathologically proven ISFT cases. Location, size, shape, density, signal intensity and gadolinium uptake were studied at CT and MRI. Data collected from diffusion-weighted imaging (DWI) (3 patients), perfusion imaging and MR spectroscopy (2 patients), and DSA (4 patients) were also analyzed. Results: The tumors most frequently arose from the intracranial meninges (7/9), while the other lesions were intraventricular. Tumor size ranged from 2.5 to 10 cm (mean = 6.6 cm). They presented multilobular shape in 6/9 patients. Most ISFTs were heterogeneous (7/9) with areas of low T2 signal intensity that strongly enhanced after gadolinium administration (6/8). Erosion of the skull was present in about half of the cases (4/9). Components with decreased apparent diffusion coefficient were seen in 2/3 ISFTs on DWI. Spectroscopy revealed elevated peaks of choline and myo-inositol. MR perfusion showed features of hyperperfusion. Conclusion: ISFT should be considered in cases of extra-axial, supratentorial, heterogeneous, hypervascular tumor. Areas of low T2 signal intensity that strongly enhance after gadolinium injection are suggestive of this diagnosis. Restricted diffusion and elevated peak of myo-inositol may be additional valuable features.

    Full Text Available Abstract: Symptomatic intracranial atherosclerotic disease (ICAD is responsible for approximately 10% of all ischemic strokes in the United States. The risk of recurrent stroke may be as high as 35% in patient with critical stenosis greater than 70% in diameter narrowing. Recent advances in medical and endovascular therapy have placed ICAD at the forefront of clinical stroke research to optimize the best medical and endovascular approach to treat this important underlying stroke etiology. Analysis of symptomatic ICAD studies lead to the question that whether angioplasty and or stenting is a safe, suitable and efficacious therapeutic strategy in patients with critical stenoses that are deemed refractory to medical management. Most of the currently available data in support of angioplasty and or stenting in high risk patients with severe symptomatic ICAD is in the form of case series and randomized trial results of endovascular therapy versus medical treatment are awaited. This is a comprehensive review of the state of the art in the endovascular approach with angioplasty and or stenting of symptomatic intracranial atherosclerotic disease.

    To evaluate the CT and MRI findings of neurosyphilis. We retrospectively reviewed the CT and MR imaging findings in five patients with intracranial neurosyphilis confirmed by CSF, VDRL, TPHA, and clinical follow-up. MR imaging was performed in all five cases, and CT in two. The MRI and CT findings of intracranial neurosyphilis included infarction (n=3), focal inflammation (n=1) and encephalopathy (n=1). There was a total of ten infaretions : three of the basal ganglia, two each of the frontal lobe, watershed zone, and cerebellum, and one of the occipital lobe. Intaretion was most common in MCA territory (n=9; 50%), followed by the watershed zone (16.6%), posterior cerebral artery territory (16.6%), and posterior inferior cerebellar artery territory (11.1%). The size of the lesion varied from 1cm to larger than one lobe. One patient showed diffuse high signal intensity in the left temporal lobe, but on follow-up MRI, this had resolved. The most common finding of neurosyphilis, as seen on MRI and CT, was infarction in middle cerebral arterial territory.

  17. Intracranial Hemorrhage Annotation for CT Brain Images

    Directory of Open Access Journals (Sweden)

    Tong Hau Lee


    Full Text Available In this paper, we created a decision-making model to detect intracranial hemorrhage and adopted Expectation Maximization(EM segmentation to segment the Computed Tomography (CT images. In this work, basically intracranial hemorrhage is classified into two main types which are intra-axial hemorrhage and extra-axial hemorrhage. In order to ease classification, contrast enhancement is adopted to finetune the contrast of the hemorrhage. After that, k-means is applied to group the potential and suspicious hemorrhagic regions into one cluster. The decision-making process is to identify whether the suspicious regions are hemorrhagic regions or non-regions of interest. After the hemorrhagic detection, the images are segmented into brain matter and cerebrospinal fluid (CSF by using expectation-maximization (EM segmentation. The acquired experimental results are evaluated in terms of recall and precision. The encouraging results have been attained whereby the proposed system has yielded 0.9333 and 0.8880 precision for extra-axial and intra-axial hemorrhagic detection respectively, whereas recall rate obtained is 0.9245 and 0.8043 for extra-axial and intra-axial hemorrhagic detection respectively.

    AIM: To explore the oncological outcomes of unresectable lung metastases without extrapulmonary metastases in colorectal cancer. METHODS: Patients with unresectable isolated lung metastases from colorectal cancer were prospectively collected in a single institution during a 5-year period. All patients received either the fluorouracil/leucovorin plus oxaliplatin, fluorouracil/leucovorin plus irinotecan or capecitabine plus oxaliplatin regimen as first-line treatment. The resectability after preoperative chemotherapy was evaluated. Patients’ outcome and predictive factors for overall survival were also investigated by univariate and multivariate analysis. RESULTS: A total of 70 patients were included in the study. After standardized first-line chemotherapy, only 4 patients (5.7%) were converted to resectable disease. The median overall survival time in all patients was 19 mo (95% CI: 12.6-25.4), with a 2-year overall survival rate of 38.8%. No survival difference was found among different first-line chemotherapeutic regimens. Prognostic analysis demonstrated that only the first response assessment for first-line treatment was the independent factor for predicting overall survival. The median survival time in partial response, stable disease and progressive disease patients were 27 mo, 16 mo and 8 mo (P = 0.00001). CONCLUSION: Pulmonary metastasectomy can only be performed in a small part of unresectable lung metastases patients after chemotherapy. Patients’ first response assessment is an important prognostic factor. PMID:20614489

    Pineal germinoma is the commonest pineal region tumor of childhood and adolescence. Metastatic germinoma most commonly occurs via the cerebrospinal fluid (CSF), and it is usually limited to the cerebrospinal axis. ExtacraniaI hematogenous metastasis is known to be very rare. We report here on a case of pineal germinoma with gradual extracranial metastases that occurred both through the CSF pathway and by hematogenous spread. The patient had multifocal CSF seeding after his surgery for pineal germinoma, and the left iliac metastasis and lung metastasis then occurred.

    Brain metastases account for 30 to 40% of all brain tumors in adults. Even if urological carcinomas are not very common, anti-angiogenic drugs have transformed their prognosis, leading physicians to consider their specific treatment. For the majority of cases, surgery is quite simple with low associated morbidity. Depending on the size and the location, surgery or stereotaxic radiotherapy should be discussed. As soon as the metastasis is suspected a neurosurgerical opinion must be sought before beginning any treatment to coordinate the global management.

    Thee cases of pituitary metastases were reported. They all had operations and the pathological examination confirming the diagnosis. The clinical features of diabetes insipidus and extraocular nerve palsy were presented. In two cases, the original tumors were bronchioloalveolar carcinoma; in the other one, the original tumor was unknown. All three cases had poor outcome. These cases illustrate the fact that a pituitary metastasis can closely mimic a pituitary benign tumor, such as pituitary adenoma. Especially in the presence of suggestive symptoms such as diabetes insipidus and/or cranical nerve paralysis, the possibility of metastatic disease in the differential diagnosis of a pituitary mass should always be considered.

    Rubegni, Pietro; Lamberti, Arianna; Mandato, Filomena; Perotti, Roberto; Fimiani, Michele


    In 2-8% of patients with melanoma, the first clinical manifestation of the disease may be skin metastasis. In these cases, differential diagnosis with the primary melanoma, benign melanocytic lesions, and other malignant and benign skin growths is particularly challenging. For this reason, the dermatologist's approach to cutaneous metastases of malignant melanoma calls for knowledge of the great morphological variety of these lesions. Dermoscopic characteristics associated with CMMMs have not yet been codified. The aim of the present review is to provide additional information about dermoscopic aspects of these skin lesions.

  5. Facial Paralysis and Hearing Loss: A Rare Manifestation of Prostate Cancer Metastases (United States)

    Saqib, Amina; Mohammad, Farhan; Raza, Muhammad R; Nalluri, Nikhil; Forte, Frank


    Dural prostate metastases (DPM) are a rare manifestation of metastatic prostate cancer seen in approximately one to six percent of cases. Presenting symptoms may include signs of elevated intracranial pressure, headache, altered mental status, or cranial nerve palsies. Hearing loss, sensory changes, dysarthria, and dysphagia are rare symptoms in DPM that were present in our patient. We present a case of a 58-year-old male with a known diagnosis of adenocarcinoma of the prostate presenting with symptoms of acute exacerbation of chronic obstructive pulmonary disease (COPD), sub-acute right-sided hearing loss, and right-sided facial paralysis. Over the course of hospitalization, his neurological symptoms worsened and he developed dysarthria, dysphagia, facial numbness, and worsening back pain. He also appeared more withdrawn and lethargic. The symptoms prompted a neurological evaluation and a magnetic resonance imaging (MRI) revealed multiple areas of bone marrow signal abnormality compatible with osseous metastatic disease. There was extensive smooth dural thickening as well as focal nodular thickening, both consistent with dural metastases. The patient was treated with corticosteroids and external beam radiation therapy (EBRT) with improvement in his back pain and facial paralysis. He died two weeks after completing EBRT. Although rare, DPM should be suspected in males over 50 years of age presenting with neurological symptoms. An MRI with gadolinium is most helpful in delineating the presence and extent of dural and calvarial involvement. Corticosteroids and EBRT have been shown to improve neurological function in up to 67% of patients. However, median survival post-radiation remains approximately three months. PMID:28409073

Historically, treatment options for melanoma brain metastases (MBM have predominantly consisted of surgery and radiotherapy. While these options can help provide local control, the majority of patients still develop intracranial progression. Indeed, novel therapeutic options, including molecularly targeted agents and immunotherapy, have improved outcomes and are now changing the role of radiotherapy. Up to 50% of melanomas contain an activating BRAF mutation, resulting in hyperactive cellular proliferation and survival. Drugs that target BRAF have been introduced for the treatment of metastatic melanoma and offer hope in improving disease outcomes; however, many of these trials either excluded or had a limited amount of patients with MBM. Recent studies have revealed that melanoma cell lines become more radiosensitive following BRAF inhibition, thus providing a potential synergistic mechanism when combining BRAF inhibitor (BRAFi and radiotherapy. However, neurotoxicity concerns also exist with this combination. This article reviews the efficacy and limitations of BRAFi therapy for MBM, describes current evidence for combining BRAFis with radiation, discusses the rationale and evidence for combination modalities, and highlights emerging clinical trials specifically investigating this combination in MBM.

  8. Molecular basis and genetic predisposition to intracranial aneurysm. (United States)

    Tromp, Gerard; Weinsheimer, Shantel; Ronkainen, Antti; Kuivaniemi, Helena


    Intracranial aneurysms, also called cerebral aneurysms, are dilatations in the arteries that supply blood to the brain. Rupture of an intracranial aneurysm leads to a subarachnoid hemorrhage, which is fatal in about 50% of the cases. Intracranial aneurysms can be repaired surgically or endovascularly, or by combining these two treatment modalities. They are relatively common with an estimated prevalence of unruptured aneurysms of 2%-6% in the adult population, and are considered a complex disease with both genetic and environmental risk factors. Known risk factors include smoking, hypertension, increasing age, and positive family history for intracranial aneurysms. Identifying the molecular mechanisms underlying the pathogenesis of intracranial aneurysms is complex. Genome-wide approaches such as DNA linkage and genetic association studies, as well as microarray-based mRNA expression studies, provide unbiased approaches to identify genetic risk factors and dissecting the molecular pathobiology of intracranial aneurysms. The ultimate goal of these studies is to use the information in clinical practice to predict an individual's risk for developing an aneurysm or monitor its growth or rupture risk. Another important goal is to design new therapies based on the information on mechanisms of disease processes to prevent the development or halt the progression of intracranial aneurysms.

  9. The Familial Intracranial Aneurysm (FIA study protocol

    Directory of Open Access Journals (Sweden)

    Meissner Irene


    Full Text Available Abstract Background Subarachnoid hemorrhage (SAH due to ruptured intracranial aneurysms (IAs occurs in about 20,000 people per year in the U.S. annually and nearly half of the affected persons are dead within the first 30 days. Survivors of ruptured IAs are often left with substantial disability. Thus, primary prevention of aneurysm formation and rupture is of paramount importance. Prior studies indicate that genetic factors are important in the formation and rupture of IAs. The long-term goal of the Familial Intracranial Aneurysm (FIA Study is to identify genes that underlie the development and rupture of intracranial aneurysms (IA. Methods/Design The FIA Study includes 26 clinical centers which have extensive experience in the clinical management and imaging of intracerebral aneurysms. 475 families with affected sib pairs or with multiple affected relatives will be enrolled through retrospective and prospective screening of potential subjects with an IA. After giving informed consent, the proband or their spokesperson invites other family members to participate. Each participant is interviewed using a standardized questionnaire which covers medical history, social history and demographic information. In addition blood is drawn from each participant for DNA isolation and immortalization of lymphocytes. High- risk family members without a previously diagnosed IA undergo magnetic resonance angiography (MRA to identify asymptomatic unruptured aneurysms. A 10 cM genome screen will be performed to identify FIA susceptibility loci. Due to the significant mortality of affected individuals, novel approaches are employed to reconstruct the genotype of critical deceased individuals. These include the intensive recruitment of the spouse and children of deceased, affected individuals. Discussion A successful, adequately-powered genetic linkage study of IA is challenging given the very high, early mortality of ruptured IA. Design features in the FIA Study

    Efficacy of palliative and prophylactic radiotherapies for metastatic bone pain and pathological fracture was investigated in 14 patients with long bone metastases. Irradiation sites were the femur in 10 patients, the humerus in 2, the radius in one, and the tibia in one. Radiographs showed osteolytic lesion in 13 patients and osteoblastic lesion in one. A total dose of 48.6 Gy to 87.3 Gy was delivered in daily fractional doses of 2 Gy (one patient), 2.5 Gy (3), 3 Gy (6), 4 Gy (2) and 5 Gy (2), 5 days a week. For 13 patients, except for one death within one month after the completion of irradiation, pain relief was attained. Of these patients, 7 (54%) had complete pain relief. In one patient, pathological fracture occurred as early as 10 days after the beginning of irradiation when irradiation efficacy was not attained. In none of the 13 others, was pathological fracture encountered. No side effects were seen at all during or after irradiation. Radiation therapy was an extremely effective means for managing patients with long bone metastases in terms of its palliative and prophylactic role. (N.K.).

  11. Unusual Orange-Colored Choroidal Metastases

    Hatem Krema


    Full Text Available Purpose: To report the clinical and paraclinical features of two patients with orangecolored choroidal metastases in whom the primary cancers have not previously been associated with such lesions. Case Report: Orange-colored choroidal lesions were detected on the fundus examination of one patient with metastatic small cell neuroendocrine tumor of the larynx and oropharynx, and in another subject with metastatic alveolar soft part sarcoma of the leg. Although ultrasonographic characteristics of the choroidal masses were comparable to those of choroidal hemangiomas, fluorescein angiography revealed delayed initial fluorescence along with minimal fluorescence in subsequent phases of the angiogram which were in clear distinction from the earlier appearing and progressively intense fluorescence observed with circumscribed choroidal hemangiomas. Conclusion: Small cell neuroendocrine tumors and alveolar soft part sarcomas should be considered among the differential diagnoses for orange-colored choroidal metastases. Identifying these choroidal lesions could facilitate localizing the occult primary tumor. Fluorescein angiography may differentiate a unifocal orange choroidal metastasis from a circumscribed choroidal hemangioma.

  12. The Surgical Treatment of Pelvic Bone Metastases

    Directory of Open Access Journals (Sweden)

    Daniel A. Müller


    Full Text Available Pelvic bone metastases are a growing concern in the field of orthopedic surgery. Patients with pelvic metastasis are individually different with different needs of treatment in order to attain the best possible quality of life despite the advanced stage of disease. A holistic collaboration among the oncologist, radiation therapist, and orthopedic surgeon is mandatory. Special attention has to be directed to osteolytic lesions in the periacetabular region as they can provoke pathological fractures and subsequent functional impairment. Different reconstruction techniques for the pelvis are available; the choice depends on the patient’s prognosis, size of the bone defect, and response of the tumor to adjuvant treatment. If all the conservative treatments are exhausted and the patient is not eligible for surgery, one of the various percutaneous ablation procedures can be considered. We propose a pelvic analogue to the treatment algorithm in long bone metastasis and a scoring system in pelvic metastasis. This algorithm aims to simplify the teamwork and to avoid under- or overtreatment of pelvic bone metastases.

  13. Uncommon mucosal metastases to the stomach

    Directory of Open Access Journals (Sweden)

    Kanthan R


    Full Text Available Abstract Background Metastases to the stomach from an extra-gastric neoplasm are an unusual event, identified in less than 2% of cancer patients at autopsy. The stomach may be involved by hematogenous spread from a distant primary (most commonly breast, melanoma or lung, or by contiguous spread from an adjacent malignancy, such as the pancreas, esophagus and gallbladder. These latter sites may also involve the stomach via lymphatic or haematogenous spread. We present three cases of secondary gastric malignancy. Methods/Results The first is a 19-year-old male who received a diagnosis of testicular choriocarcinoma in September 2004. Metastatic malignancy was demonstrated in the stomach after partial gastrectomy was performed to control gastric hemorrhage. The second is a 75-year-old male, generally well, who was diagnosed with adenocarcinoma of the lung in September 2005. Poorly differentiated adenocarcinoma of the lung was demonstrated in a subsequent biopsy of "gastric polyps". The third is an 85-year-old man with no known history of malignancy who presented for evaluation of iron deficiency anemia by endoscopy in February 2006. Biopsies of the colonic and gastric mucosa demonstrated moderately differentiated invasive colonic adenocarcinoma with metastatic deposits in the stomach. Conclusion While the accurate recognition of these lesions at endoscopy is fraught with difficulty, pathological awareness of such uncommon metastases in the gastric mucosa is essential for accurate diagnosis and optimal patient management.

    Full Text Available Objectives. To evaluate whether retroperitoneal approach for adrenalectomy is a safe and effective treatment for adrenal metastases (AM. Methods. From June 2004 to January 2014, nine consecutive patients with AM were treated with endoscopic retroperitoneal adrenalectomy (ERA. A retrospective study was conducted, and clinical data, tumor characteristics, and oncologic outcomes were acquired and analyzed. Results. Renal cancer was the primary site of malignancy in 44.4% of cases. The mean operative time was 132 ± 10.4 min. There were 5 synchronous and 4 metachronous AM. One patient required conversion to transperitoneal laparoscopic procedure. No mortality or perioperative complications were observed. The median overall survival was 11 months (range: 2–42 months. Survival rates of 50% and 25% were identified at 1 and 3 years, respectively. At the end of the study, 4 patients were alive with a mean observed follow-up of 20 months. No patients presented with local tumor relapse or port-site metastases. Conclusions. This study shows that ERA is a safe and effective procedure for resection of AM and advances the surgical treatment of adrenal disease. The use of the retroperitoneal approach for adrenal tumors less than 6 cm can provide very favorable surgical outcomes.

  15. Intracranial structural alteration predicts treatment outcome in patients with spontaneous intracranial hypotension. (United States)

    Choi, Hanna; Lee, Mi Ji; Choi, Hyun Ah; Cha, Jihoon; Chung, Chin-Sang


    Background Intracranial structural dislocation in spontaneous intracranial hypotension (SIH) can be measured by various intracranial angles and distances. We aimed to identify the clinical significance of structural dislocation in relation to treatment outcome in patients with SIH. Methods In this retrospective analysis, we identified patients with SIH who received an epidural blood patch (EBP) at Samsung Medical Center from January 2005 to March 2015. Structural dislocation in pretreatment MRIs of SIH patients was assessed by measuring tonsillar herniation, mamillopontine distance, the angle between the vein of Galen and straight sinus (vG/SS angle), the pontomesencephalic angle, and the lateral ventricular angle. After the first EBP, poor response was defined as the persistence of symptoms that prompted a repeat EBP. Results Out of the 95 patients included, 31 (32.6%) showed poor response. Among the radiological markers of structural dislocation, the vG/SS angle was associated with poor response (49.82 ± 16.40° vs 66.58 ± 26.08°, p = 0.002). Among clinical variables, premorbid migraine ( p = 0.036) was related to poor response. In multivariate analysis, reduced vG/SS angle was independently associated with poor response (OR 1.04 [95% CI 1.01 - 1.07] per 1° decrease, p = 0.006). In 23 patients who underwent MRI after successful treatment, the vG/SS angle significantly increased after the EBP ( p < 0.001, by paired t-test), while two patients with aggravation or recurrence showed a further reduction of their vG/SS angles. Conclusions Intracranial structural dislocation, measured by the vG/SS angle, is associated with poor response to the first EBP in patients with SIH. Successful treatment can reverse the structural dislocation.

    Abstract The aim of this study was to investigate whether there is a long-term improvement in headache of patients with unruptured intracranial aneurysms (UIAs) treated with intracranial endovascular procedures. Using a prospective design, consecutive patients with UIAs with neuroendovascular treatment from January 2014 to December 2014 were asked to participate. Headache outcomes were established before aneurysm treatment and for 6 months following treatment. Factors associated with different headache outcomes were investigated. Ultimately, 58 patients completed the 6-month follow-up. In total, 29 patients had preoperative headache. Six months after the intracranial endovascular procedure, 13 patients (44.8%) stated that their headaches were relieved after endovascular treatment; headache in 1 patient improved slightly, and 12 reported disappearance of headache and marked improvement. Overall, the mean headache scores of 29 patients improved on the self-reported Numeric Rating Scale (NRS) after endovascular treatment (6.00 vs. 2.30; P aneurysm were the important disadvantage for patients in improvement of post-procedure headache. Treatment of UIAs resulted in relief of headaches in about half of patients who had headaches pre-operatively. PMID:28178166

    Full Text Available The syndrome of multiple enchondromas is known as Ollier′s disease. Enchondromas are benign tumours of hyaline cartilage arising within the medullary cavity of tubular bones. We are reporting the case of a 16 year old girl with Ollier′s disease who presented with seizures and brainstem compression. A MRI scan of brain showed an intracranial space-occupying lesion in the region of clivus. The intracranial tumour was surgically removed and the histopathology confirmed the diagnosis of enchondroma. Intracranial enchondroma is an extremely rare situation and reported for the first time from south India.

  9. Musical hallucinations associated with seizures originating from an intracranial aneurysm. (United States)

    Roberts, D L; Tatini, U; Zimmerman, R S; Bortz, J J; Sirven, J I


    Hallucinations are defined as sensory phenomena in the absence of external sensory stimuli. Auditory hallucinations have been shown to arise from many different intracranial lesions, but seizures manifesting as musical hallucinations triggered by unruptured intracranial aneurysms are rare. We present a case of persistent, episodic musical hallucinations associated with seizures that led to the discovery of 2 small intracranial aneurysms. Typical electroencephalographic findings for seizure activity were observed but resolved after surgical clipping of the aneurysms. Concomitantly, the patient's hallucinations resolved. The literature on musical hallucinations is reviewed.

  11. Management of dual intracranial germinoma by radiotherapy alone

    Directory of Open Access Journals (Sweden)

    Rakesh Gupta


    Full Text Available Synchronous intracranial germ cell tumor in the pineal and suprasellar region is rare. They represent only 5-10% of all intracranial germinomas. They are also known by the entity "double midline atypical teratoma" and are common in the second decade of life. We report a case of an 11-year-old girl having dual midline intracranial lesions with obstructive hydrocephalus treated by ventriculo-peritoneal shunt. Diagnosis of germinoma was made on the basis of imaging and elevated beta-human chorionic gonadotropin in cerebrospinal fluid. Radiotherapy was instituted, which resulted in the total disappearance of both the lesions. Clinical expression, diagnosis and management strategies are discussed.

    Petrou, Panayota; Moscovici, Samuel; Leker, Ronen R; Itshayek, Eyal; Gomori, John M; Cohen, José E


    The use of a ventriculoperitoneal (VP) shunt to treat uncontrollable intracranial hypertension in patients with cryptococcal meningitis without hydrocephalus is somewhat unusual and still largely unreported. However, uncontrollable intracranial hypertension without hydrocephalus in these patients is a potentially life-threatening condition. Early diagnosis and shunt placement are essential to improve survival and neurological function. We report uncontrollable intracranial hypertension without hydrocephalus in a 23-year-old woman, which was successfully managed by VP shunt placement. Copyright © 2012 Elsevier Ltd.

  14. Intracranial drug delivery for subarachnoid hemorrhage. (United States)

    Macdonald, Robert Loch; Leung, Ming; Tice, Tom


    Tice and colleagues pioneered site-specific, sustained-release drug delivery to the brain almost 30 years ago. Currently there is one drug approved for use in this manner. Clinical trials in subarachnoid hemorrhage have led to approval of nimodipine for oral and intravenous use, but other drugs, such as clazosentan, hydroxymethylglutaryl CoA reductase inhibitors (statins) and magnesium, have not shown consistent clinical efficacy. We propose that intracranial delivery of drugs such as nimodipine, formulated in sustained-release preparations, are good candidates for improving outcome after subarachnoid hemorrhage because they can be administered to patients that are already undergoing surgery and who have a self-limited condition from which full recovery is possible.

  15. Intracranial Aspergillosis in an Immunocompetent Young Woman. (United States)

    Panda, Prasan Kumar; Mavidi, Sunil Kumar; Wig, Naveet; Garg, Ajay; Nalwa, Aasma; Sharma, M C


    Intracranial aspergillosis (ICA) is very rare in the immunocompetent individuals, usually misdiagnosed as a tumor or an abscess. A high index of clinical suspicion is required in patients who present with focal neurological deficits, headache, or seizures. We report the case of a 25-year-old immunocompetent female, who presented with a 15-month history of headache, seizures, left-sided proptosis and ophthalmoplegia, and right hemiparesis. Recovery from the symptoms and decrease in the lesion size seen on the radiological assessment were achieved through two decompressive craniotomies followed by prolonged combined systemic antifungal therapies. Although the initial neuroimaging suggested a mitotic pathology, the surgical sample confirmed ICA. Now the patient is on single antifungal therapy (Tab. voriconazole, 200 mg twice daily) and doing her daily activities, but with a reduced intelligent quotient. We report a challenging case of ICA where multiple courses of combined antifungal therapies and repeat surgeries paved the way for a good prognosis.

  16. Rapid virtual stenting for intracranial aneurysms (United States)

    Zhao, Liang; Chen, Danyang; Chen, Zihe; Wang, Xiangyu; Paliwal, Nikhil; Xiang, Jianping; Meng, Hui; Corso, Jason J.; Xu, Jinhui


    The rupture of Intracranial Aneurysms is the most severe form of stroke with high rates of mortality and disability. One of its primary treatments is to use stent or Flow Diverter to divert the blood flow away from the IA in a minimal invasive manner. To optimize such treatments, it is desirable to provide an automatic tool for virtual stenting before its actual implantation. In this paper, we propose a novel method, called ball-sweeping, for rapid virtual stenting. Our method sweeps a maximum inscribed sphere through the aneurysmal region of the vessel and directly generates a stent surface touching the vessel wall without needing to iteratively grow a deformable stent surface. Our resulting stent mesh has guaranteed smoothness and variable pore density to achieve an enhanced occlusion performance. Comparing to existing methods, our technique is computationally much more efficient.

  17. Chronic inflammatory demyelinating polyradiculoneuropathy associated intracranial hypertension. (United States)

    Altinkaya, Ayca; Topcular, Baris; Sakalli, Nazan Karagoz; Kuscu, Demet Yandim; Kirbas, Dursun


    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired immune-mediated demyelinating neuropathy. In this report, we detail the course of a 58-year-old male patient who had headache and double vision followed by progressive paresthesia and difficulty in walking. The patient had bilateral papilledema and mild leg weakness, absent ankle jerks and loss of sensation in distal parts of his lower and upper extremities. His electromyography (EMG) was concordant with CIDP and lumbar puncture revealed high opening pressure. The polyradiculoneuropathy as well as the papilledema and elevated cerebrospinal fluid (CSF) pressure improved under steroids. The improvement in intracranial hypertension (IHT) and papilledema under steroid treatment suggests that the IHT in this patient might be associated with CIDP.

    We reviewed MRI findings in proven intracranial germ cell tumours in 22 cases, 12 of whom received Gd-DTPA. On T1-weighted images, the signal intensity of the tumour parenchyma was moderately low in 19 cases and isointense in 3; on T2-weighted images, it was high in all cases. Regions of different intensity thought to be cysts were found in 17 (77 %): 7 of 12 patients with germinoma (58 %) and in all other cases. Of the 13 patients with pineal lesions T1-weighted sagittal images showed the aqueduct to be obstructed in 5, stenotic in 7 and normal in 1. Strong contrast enhancement was observed in all 12 cases. Of the 14 patients with suprasellar lesions, 5 were found to have an intrasellar extension, and in 3 of these, the normal pituitary gland, which could be distinguished from the tumour, was displaced anteriorly. Ten patients (45 %) had multiple lesions. (orig.)

  19. Intracranial meningeal chondrosarcoma--probable mesenchymal type. (United States)

    Rodda, R A; Franklin, C I


    A 12 year old girl with episodes of left hemiparesis for 9 months was found to have a large, partly calcified brain tumour which at craniotomy presented on the parasagittal and medial surfaces of the right frontal lobe. No dural or falx attachment could be found and naked eye removal of the tumour was achieved. At a second craniotomy 10 weeks later there was recurrent tumour attached to the falx and involving the sagittal sinus. She died 5 months later. Pathologically, almost all this malignant intracranial neoplasm comprised differentiated cartilaginous tumour. Although only a very small amount of undifferentiated mesenchymal tissue was found in the surgical material available for histological study, it is suggested the tumour can be regarded as a predominantly mature mesenchymal chondrosarcoma of the meninges.

    BACKGROUND: Parkinson's disease (PD) and multiple system atrophy (MSA) are neurodegenerative diseases that can be difficult to diagnose and distinguish from each other. STUDY AIMS AND METHODS: Patients with PD and MSA and controls were studied with magnetic resonance imaging (MRI) using tissue...... segmentation and outlining of regions in order to identify regional volume changes that might be useful in the diagnosis of the two diseases. RESULTS: Patients with PD had significantly larger intracranial volumes (ICVs) and significantly smaller putaminal and sustantia nigra volumes than controls. MSA...... or compensatory responses to early CNS damage. Atrophy of the amygdala in MSA patients has not been demonstrated with MR before. It might explain why these patients can have hyposmia. The putaminal atrophy found in the PD group may be a trait of the later stages of PD. Segmentation of the substantia nigra can...

  1. Visual Impairment/Intracranial Pressure Risk Assessment (United States)

    Fogarty, Jennifer A.; Durham, T.; Otto, C.; Grounds, D.; Davis, J. R.


    Since 2006 there have been 6 reported cases of altered visual acuity and intracranial pressure (ICP) in long duration astronauts. In order to document this risk and develop an integrated approach to its mitigation, the NASA Space Life Sciences Directorate (SLSD) and Human Research Program (HRP) have chosen to use the Human System Risk Board (HSRB) and the risk management analysis tool (RMAT). The HSRB is the venue in which the stakeholders and customers discuss and vet the evidence and the RMAT is the tool that facilitates documentation and comparison of the evidence across mission profiles as well as identification of risk factors, and documentation of mitigation strategies. This process allows for information to be brought forward and dispositioned so that it may be properly incorporated into the RMAT and contribute to the design of the research and mitigation plans. The evidence thus far has resulted in the identification of a visual impairment/intracranial pressure (VIIP) project team, updating of both short and long duration medical requirements designed to assess visual acuity, and a research plan to characterize this issue further. In order to understand this issue more completely, a plan to develop an Accelerated Research Collaboration (ARC) has been approved by the HSRB. The ARC is a novel research model pioneered by the Myelin Repair Foundation. It is a patient centered research model that brings together researchers and clinicians, under the guidance of a scientific advisory panel, to collaborate and produce results much quickly than accomplished through traditional research models. The data and evidence from the updated medical requirements and the VIIP ARC will be reviewed at the HSRB on a regular basis. Each review package presented to the HSRB will include an assessment and recommendation with respect to continuation of research, countermeasure development, occupational surveillance modalities, selection criteria, etc. This process will determine the

  2. Endoscope-assisted microsurgery for intracranial aneurysms. (United States)

    Kalavakonda, Chandrasekar; Sekhar, Laligam N; Ramachandran, Pranatartiharan; Hechl, Peter


    We discuss the role of the endoscope in the microsurgical treatment of intracranial aneurysms, analyzing its benefits, risks, and disadvantages. This was a prospective study of 55 patients with 79 aneurysms, treated between July 1998 and June 2001, for whom the endoscope was used as an adjunct in the microsurgical treatment of their lesions. Seventy-one aneurysms were located in the anterior circulation, and eight were located in the posterior circulation. Thirty-seven patients presented with subarachnoid hemorrhage. Eighteen patients had unruptured aneurysms, of whom 5 presented with mass effect, 2 presented with transient ischemic attacks, and 11 were without symptoms. In all cases, the endoscope was used in addition to microsurgical dissection and clipping (sometimes before clipping, sometimes during clipping, and always after clipping), for observation of the neck anatomic features and perforators and verification of the optimal clip position. Intraoperative angiography was performed for all patients after aneurysm clipping. In the majority of cases, the endoscope was very useful for the assessment of regional anatomic features. It allowed better observation of anatomic features, compared with the microscope, for 26 aneurysms; in 15 cases, pertinent anatomic information could be obtained only with the endoscope. The duration of temporary clipping of the parent artery was significantly reduced for two patients. The clip was repositioned because of a residual neck or inclusion of the parent vessel during aneurysm clipping in six cases, and the clip position was readjusted because of compression of the optic nerve in one case. One patient experienced a small aneurysm rupture that was directly related to use of the endoscope, but this was easily controlled, with no sequelae. For many patients, the combination of the neuro-endoscope and the micro-Doppler probe made intraoperative angiography redundant. "Endoscope-assisted microsurgery" is a major advance in the

    Full Text Available Background:The endovascular techniques has widely changed the treatment of intracranial aneurysms.However surgery still represent the best therapeutic option in case of broad-based and complex lesions.The combined use of endoscopic and microsurgical techniques (EAM may improve surgical results. Objective:The purpose of our study is to evaluate the advantages and limits of EAM for intracranial aneurysms.Methods:Between January 2002 and December 2012,173 patients,harbouring 206 aneurysms were surgically treated in our department with the EAM technique.157 aneurysms were located in the anterior circulation and 49 were in the posterior circulation.Standard tailored approaches,based on skull base surgery principles,were chosen.The use of the endoscope included three steps:initial inspection,true operative time and final inspection.For each procedure,an intraoperative video and an evaluation schedule were prepared,to report surgeons’ opinions about the technique itself.In the first cases,we always used the endoscope during surgical procedures in order to get an adequate surgical training.Afterwards we became aware in selecting cases in which to apply the endoscopy,as we started to become familiar with its advantages and limits.Results:After clipping,all patients were undergone postoperative cerebral angiography.No surgical mortality related to EAM were observed.Complications directly related to endoscopic procedures were rare.Conclusions:Our retrospective study suggests that endoscopic efficacy for aneurysms is only scarcely influenced by the preoperative clinical condition (Hunt-Hess grade,surgical timing,presence of blood in the cisterns (Fisher grade and/or hydrocephalus.However the most important factors contributing to the efficacy of EAM are determined by the anatomical locations and sizes of the lesions.Furthermore,the advantages are especially evident using dedicated scopes and holders,after an adequate surgical training to increase the

    Full Text Available Introduction: The purpose of this study is to evaluate the distribution, clinical features, and treatment modalities of arachnoid cyst in our department. The study was carried out between April 1, 1996 and October 1, 2006 at the neurosurgery department, Ghaem hospital, Mashhad university of medical sciences. Material and Methods: Twenty patients with arachnoid cyst underwent surgery between April 1, 1996 until October 1, 2006, consisting of 12 males and 8 females ranging in age 5 to 68 years (mean age 32.4 years. Twelve patients underwent surgery and one patient underwent endoscopic fenestration, and cystoperitoneal shunting (medium pressure was performed in 7 patients. All patients were followed for minimum of 6 months after surgery. Results: During the study period, 20 patients were investigated. The cysts had strong predilection for the middle cranial fossa in 12 patients (60%, suprasellar region in 1 patient (5%, the cerebral convexity in 1 patient (5%, posterior cranial fossa in 2 patients (10%, cerebellopontine angle in 3 patients (15%, quadrigeminal cisterns in 1 patient (5%. All of 20 cysts had clearly unilateral distribution, 12 (60% were located on the left side and 8 (40% on the right side. The most common symptoms on presentation were epileptic seizures (46%, increased intracranial pressure (34%, visual impairment (5%, headache (10%, cerebellar sign (5%. Conclusion: Arachnoid cysts have a strong predilection for the middle cranial fossa that may be explained by a meningeal maldevelopment theory. We also conclude that the major indication for surgery in patients with arachnoid cyst is the presence of intractable seizures, increased intracranial pressure, and compression of neuronal tissues. Headache only is not a surgical indication.

    Purpose: To evaluate local control after surgical resection and postoperative stereotactic radiosurgery (SRS) for brain metastases. Methods and Materials: A total of 49 patients (50 lesions) were enrolled and available for analysis. Eligibility criteria included histologically confirmed malignancy with 1 or 2 intraparenchymal brain metastases, age ≥18 years, and Karnofsky performance status (KPS) ≥70. A Cox proportional hazard regression model was used to test for significant associations between clinical factors and overall survival (OS). Competing risks regression models, as well as cumulative incidence functions, were fit using the method of Fine and Gray to assess the association between clinical factors and both local failure (LF; recurrence within surgical cavity or SRS target), and regional failure (RF; intracranial metastasis outside of treated volume). Results: The median follow-up was 12.0 months (range, 1.0-94.1 months). After surgical resection, 39 patients with 40 lesions were treated a median of 31 days (range, 7-56 days) later with SRS to the surgical bed to a median dose of 1800 cGy (range, 1500-2200 cGy). Of the 50 lesions, 15 (30%) demonstrated LF after surgery. The cumulative LF and RF rates were 22% and 44% at 12 months. Patients who went on to receive SRS had a significantly lower incidence of LF (P=.008). Other factors associated with improved local control include non-small cell lung cancer histology (P=.048), tumor diameter <3 cm (P=.010), and deep parenchymal tumors (P=.036). Large tumors (≥3 cm) with superficial dural/pial involvement showed the highest risk for LF (53.3% at 12 months). Large superficial lesions treated with SRS had a 54.5% LF. Infratentorial lesions were associated with a higher risk of developing RF compared to supratentorial lesions (P<.001). Conclusions: Postoperative SRS is associated with high rates of local control, especially for deep brain metastases <3 cm. Tumors ≥3 cm with superficial dural

    Lung cancer is one of the most frequent malignancies, with high mortality rates. It can metastasize in almost all organs, but more often invades hilar nodes, liver, adrenal glands, bones and brain. There are various data on the incidence of lung cancer metastases in the skin. In 1-12% of patients with lung cancer are developed skin metastases. Metastases in the skin may be the first sign of lung cancer. Forty-five years old Albanian male, smoker, was admitted to our department with multiple nodules localized in the skin of the head, neck, back and chest. The nodules measuring 5-15 millimeters in greatest dimension were round and skin-colored, with telangiectasias, firm and tender. They appeared in an eruptive form about two weeks before being admitted at our hospital. In addition, the patient exhibited signs of weight loss, anorexia and fatigue. Excisional biopsy was performed to one of the lesions. Histopathology confirmed metastatic nature of the lesion namely, malignant tumor of neuroendocrine phenotype consistent with small-cell carcinoma. Chest X-ray and computed tomography revealed an expansive process in the 7(th) segment of the left lung, left hilar and mediastinal lymphadenopathy and a suspicious initial secondary deposit in the left adrenal gland. The patient was referred to the department of oncology for further treatment. After the third cycle of chemotherapy, the magnetic resonance imaging revealed brain metastases. The patient passed away four months after the diagnosis of lung cancer first presented with skin metastases. Metastases in skin may be the first sign of lung cancer. Although rare appearing, we should raise suspicion in cases of atypical lesions in the skin not only of the smokers, but also of the non-smokers. Skin metastases from small-cell lung carcinoma are a poor prognostic indicator. The appearance of multiple skin metastases with other internal metastases shorten the survival time.

The use of epidermal growth factor receptor (EGFR tyrosine kinase inhibitors (TKIs to treat brain metastases remains controversial. Thus, we performed a pooled analysis of published data to evaluate the efficacy of EGFR-TKIs in NSCLC patients with brain metastases, particularly for tumors with activating EGFR mutations. Methods: Several data sources were searched, including PubMed, Web of Science, and ASCO Annual Meetings databases. The end points were intracranial overall response rate (ORR, disease control rate (DCR, progression-free survival (PFS, overall survival (OS, and adverse events. The pooled ORR, DCR, PFS, and OS with 95% confidence intervals (CIs were calculated employing fixed- or random-effect models, depending on the heterogeneity of the included studies. Results: Sixteen published studies were included in this analysis, with a total of 464 enrolled patients. The EGFR mutational status was unknown for 362 (unselected group, and 102 had activating EGFR mutations. The pooled intracranial ORR and DCR were 51.8% (95% CI: 45.8%–57.8% and 75.7% (95% CI: 70.3%–80.5%, respectively. A higher ORR was observed in the EGFR mutation group than in the unselected group (85.0% vs 45.1%; a similar trend was observed for the DCR (94.6% vs 71.3%. The pooled median PFS and OS were 7.4 months (95% CI, 4.9–9.9 and 11.9 months (95% CI, 7.7–16.2, respectively, with longer PFS (12.3 months vs 5.9 months and OS (16.2 months vs

    Dissemination of high-grade gliomas (WHO IV) has been investigated poorly so far. We conducted an extensive analysis of the characteristics, treatments and outcomes of the glioblastoma multiforme (GBM)/gliosarcoma (GS) patients with central nervous system (CNS) metastases reported in literature until April 2013. PubMed and Web of Science searches for peer-reviewed articles pertaining to GBM/GS patients with metastatic disease were conducted using predefined keywords. Additionally, we performed hand search following the references from the selected papers. Cases in which the metastases exclusively occurred outside the CNS were excluded. 110 publications reporting on 189 patients were eligible. There was a significant increase in the number of reported cases over the last decades. We calculated a median overall survival from diagnosis of metastasis (from initial diagnosis of GBM/GS) of 3.0 ± 0.3 (11 ± 0.7) months. On univariate analyses, gender, age, the histological subtype, the time interval between initial diagnosis and the occurrence of metastases and the location of CNS metastasis (intracranial versus spinal and parenchymal versus leptomeningeal, respectively) did not influence survival after diagnosis of metastasis. There was no substantial treatment progress over the recent decades. GBM/GS with CNS metastasis are associated with a dismal prognosis. Crucial treatment progress is not evident. A central registry should be considered to consecutively gain more information about the ideal therapeutic approach.

    High expression of fibrinogen and platelets are often observed in non-small cell lung cancer (NSCLC) patients with local regional or distant metastasis. However, the role of these factors remains unclear. The aims of this study were to evaluate the prognostic significance of plasma fibrinogen concentration and platelet count, as well as to determine the overall survival of NSCLC patients with brain metastases. A total of 275 NSCLC patients with brain metastasis were enrolled into this study. Univariate analysis showed that high plasma fibrinogen concentration was associated with age≥65 years (P = 0.011), smoking status (P = 0.009), intracranial symptoms (P = 0.022), clinical T category (P = 0.010), clinical N category (P = 0.003), increased partial thromboplastin time (P low plasma fibrinogen concentration demonstrated longer overall survival compared with those with high plasma fibrinogen concentration (median, 17.3 months versus 11.1 months; P≤0.001). A similar result was observed for platelet counts (median, 16.3 months versus 11.4 months; P = 0.004). Multivariate analysis showed that both plasma fibrinogen concentration and platelet count were independent prognostic factors for NSCLC with brain metastases (R2 = 1.698, P high plasma fibrinogen concentration and platelet count indicate poor prognosis for NSCLC patients with brain metastases. Thus, these two biomarkers might be independent prognostic predictors for this subgroup of NSCLC patients.

    higher RPA class (HR 2.26; p = 0.03) in univariate analysis. In this series, the main prognostic factors associated with OS were performance status, time of appearance of intracranial disease (synchronous vs. metachronous), initial response to chemotherapy and higher RPA class. NPFS was negatively influenced by poor KPS, multiplicity of brain metastases, and higher RPA class in univariate analysis. For patients with low performance status, metachronous disease or RPA class III, WBRT should be weighed against supportive therapy with steroids alone or palliative chemotherapy.

    Full Text Available Idiopathic intracranial hypertension (IIH is characterized by an increased intracranial pressure in the absence of a tumor and in the absence of a venous thrombosis. Associated risk factors include obesity and several medications such as tetracyclines. We report a 60-year-old patient who developed IIH under treatment with imatinib. To our knowledge such a possible connection has not been reported in the literature, even though intracranial hypertension is now listed as a rare possible side effect of treatment with imatinib in the Swiss List of Medications Arzneimittelkompendium. It remains to be seen, if further case reports will support this observation.

    Radiotherapy for bone metastases represents an important part of daily practice in our departments of radiotherapy. Majority of treatments deliver either one fraction (6 to 10 Gy) or multi-fractions mainly using 30 Gy in ten fractions. In the past decade, several randomized trials aimed to determine the optimal scheme of radiotherapy in this setting. In the present review, the efficacy of radiotherapy on bone metastases will be evaluated using the following parameters: the partial or complete responses on pain, the reduction of antalgic intake, bone re-calcification, and need for reirradiation. Other parameters must also be considered, such as the primary site, number of metastasis, performance status, overall prognosis and side effects of radiotherapy. (authors)

    Kreutz, Julie; Potorac, Iulia; Lutteri, Laurence; Gennigens, Christine; Martin, Didier; Daly, Adrian F; Bonneville, Jean-Francois; Tshibanda, Luaba; Beckers, Albert


    Adipsic diabetes insipidus is a rare complication of intracranial tumors in which impaired antidiuretic hormone secretion is associated with the loss of thirst sensation. Here, we present the case of a patient with bifocal intracranial germinoma, diagnosed due to symptoms mainly caused by adipsic diabetes insipidus. This is, to our knowledge, the first case of adipsic diabetes insipidus revealing an intracranial germinoma reported in the literature. We describe the diagnostic procedures and the three-year follow-up of this patient. Management of intracranial germ-cell tumors is made complex by the wide range of histological features. Although germinomas have a generally better prognosis than most nongerminomatous tumors, they can have severe or even life-threatening presentations. Adipsic diabetes insipidus is one such severe presentation and its rarity can make it difficult to recognize and manage. Awareness of this potential entity is therefore important for clinical practice. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Since 2009, this technique completes our trauma protocol. The study has been carried out from 2011 to 2013 in Prof. Dr. N. Oblu hospital in Iasi. There have been included in the study patients with severe craniocerebral trauma, who had traumatic brain lesions CT detected and Glasgow score between 3 and 8. The age ranged from 16 to 60, an average of 35.5 years old. 50% of the studied cases had a favorable outcome. Diagrams associated to this category of patients showed increases in intracranial pressure above normal values but without repeated values above 50 mm Hg. Most of those patients had a good evolution under medical treatment. Monitoring intracranial pressure is an extremely useful stage in treating intracranial high pressure in traumatology and it should be included in the equipment of any intensive therapy section caring traumatic patients

    Full Text Available Bedside sonographic measurement of optic nerve sheath diameter can aid in the diagnosis of elevated intracranial pressure in the emergency department. This case report describes a 21-year-old female presenting with 4 months of mild headache and 2 weeks of recurrent, transient binocular vision loss. Though limited by patient discomfort, fundoscopic examination suggested the presence of blurred optic disc margins. Bedside ocular ultrasound (BOUS revealed wide optic nerve sheath diameters and bulging optic discs bilaterally. Lumbar puncture demonstrated a cerebrospinal fluid (CSF opening pressure of 54 cm H2O supporting the suspected diagnosis of idiopathic intracranial hypertension. Accurate fundoscopy can be vital to the appropriate diagnosis and treatment of patients with suspected elevated intracranial pressure, but it is often technically difficult or poorly tolerated by the photophobic patient. BOUS is a quick and easily learned tool to supplement the emergency physician’s fundoscopic examination and help identify patients with elevated intracranial pressure.

    Evangelos P Misiakos; Nikolaos P Karidis; Gregoryr Kouraklis


    Surgical resection offers the best opportunity for survival in patients with colorectal cancer metastatic to the liver, with five-year survival rates up to 58% in selected cases. However, only a minority are resectable at the time of diagnosis. Continuous research in this field aims at increasing the percentage of patients eligible for resection, refining the indications and contraindications for surgery , and improving overall survival. The use of surgical innovations, such as staged resection, portal vein embolization, and repeat resection has allowed higher resection rates in patients with bilobar disease. The use of neoadjuvant chemotherapy allows up to 38% of patients previously considered unresectable to be significantly downstaged and eligible for hepatic resection. Ablative techniques have gained wide acceptance as an adjunct to surgical resection and in the management of patients who are not surgical candidates. Curent management of colorectal liver metastases requires a multidisciplinary approach, which should be individu alized in each case.

  1. Novel approaches to treating leptomeningeal metastases. (United States)

    Grewal, Jai; Saria, Marlon Garzo; Kesari, Santosh


    Leptomeningeal metastasis is a devastating complication of the central nervous system in patients with late-stage solid or hematological cancers. Leptomeningeal metastasis results from the multifocal seeding of the leptomeninges by malignant cancer cells. Although central nervous system metastasis usually presents in patients with widely disseminated and progressive late-stage cancer, malignant cells may spread to the cerebrospinal fluid during earlier disease stages in particularly aggressive cancers. Treatment of leptomeningeal metastasis is largely palliative but will often provide stabilization and protection from further neurological deterioration and improve quality of life. There is a need to raise awareness of the impact of leptomeningeal metastases on cancer patients and its known and putative biological basis. Novel diagnostic approaches include identification of biomarkers that may stratify the risk for developing leptomeningeal metastasis. Current therapies can be used more effectively while waiting for advanced treatments to be developed.

    Nohad Hanbala


    Full Text Available Cutaneous metastases of rectal carcinoma is a rare event. It occurs in fewer than 4% of all patients with rectal cancer. When present, it typically signifies a disseminated disease with a poor prognosis. Early detection and proper diagnosis of metastatic rectal cancer can significantly alter treatment and prognosis. We report a 70-year-oldmale who underwent rectal resection with permanent colostomy for rectal adenocarcinoma since seven years. The patient recently developed multiple skin nodules, mainly in his face, scalp, and upper trunk, associated with itching. Fine needle aspiration cytology from a face nodule was done which revealed metastatic adenocarcinoma associated with severe inflammation. Cutaneous metastasis of rectaladenocarcinoma is an unusual event that presents mainly in the form of skin nodules and could be the first sign of metastasis. Early diagnosis of cutaneous metastasis in these patients is important because it can alter treatment and prognosis.

Herein, we are reporting a rare case of a 61-year-old man with nasopharyngeal carcinoma (NPC who presented with 3 weeks history of blood streaked sputum, post nasal drip and blocked nose with no history of epistaxis, tinnitus and unilateral hearing loss. Almost 2 years upon completion of his concurrent chemotherapy and radiotherapy, he developed a right hypochondrium mass and underwent colonoscopy which revealed a mass in ascending colon and which was then subsequently resected via right hemicolectomy. Histological analyses from the resected specimen confirmed its nasopharyngeal origin.

    Choroidal and skin metastasis of colon cancer is rare. In women, the frequency of cutaneous metastasis from colon cancer as the primary lesion in is 9% and skin metastasis occurs in 0.81% of all colorectal cancers. We report a patient with colonic adenocarcinoma who presented with visual disorder in her right eye and scalp pain as her initial symptoms. Contrast-enhance orbital magnetic resonance imaging with fat suppression revealed an infrabulbar mass, and skin biopsy of the posterior parietal scalp confirmed adenocarcinoma. These symptoms were diagnosed as being caused by choroidal and skin metastases of colonic adenocarcinoma. We started palliative chemotherapy with oral capecitabine (1000 mg/m(2), twice a day, on days 1-14) every 3 wk, which was effective at shrinking the brain masses and improving the visual disorder. This is the first report that capecitabine is effective at reducing a choroidal and cutaneous metastatic lesion from right-sided colorectal cancer.

    Kamlesh S Bhaisora


    Full Text Available Traumatic intracranial aneurysms (TICA are rare in occurrence, constituting less than 1% of the total cases of intracranial aneurysms. Cervical posttraumatic aneurysms arising from major blood vessels supplying the brain are also extremely rare. Their variable locations, morphological variations and the presence of concomitant head injury makes their diagnosis and treatment a challenge. In this review, we discuss the epidemiology, etiology, classification and management issues related to TICA as well as traumatic neck aneurysms and review the pertinent literature.

  12. [Congenital anomalies of cerebral artery and intracranial aneurysm]. (United States)

    Nakajima, K; Ito, Z; Hen, R; Uemura, K; Matsuoka, S


    It is well known that congenital anomalies such as polycystic kidney, aortic coarctation, Marfan syndrome, Ehler-Danlos syndrome are apt to be complicated by intracranial aneurysms. In this report we attempt to reveal the relation and incidence between cerebrovascular anomalies and intracranial aneurysms. The etiology of aneurysms has been discussed, too. 12 cases of persistent trigeminl artery, 2 cases of persistent hypoglossal artery and 11 cases of fenestration were obtained from 3841 patients who were angiographically examined in our clinic for 5 years. The incidence is 0.31%, 0.05% and 0.29%, respectively. Persistent trigeminal arteries were complicated by 2 cases of intracranial aneurysms and one case of arterivenous malformations (AVM), persistent hypoglossal arteries were complicated by one case of aneurysm, and fenestrations were complicated by 2 cases of aneurysms and one case of AVM. One case of congenital agenesis of right internal carotid artery was obtained which was complicated by aneurysm of anterior communicating artery. Totally, 8 cases of aneurysms and AVM were obtained from 26 cases of cerebrovascular anomalies (incidence 30.8%). On the other hand, thalamic or caudate hemorrhage revealed the highest incidence of complication of intracranial aneurysms among intracerebral hematomas (10.7%). Compared with the incidence of aneurysms between cerebro vascular anomalies (30.8%) and thalamic or caudate hemorrhage (10.7%), the difference is statistically signigicant (P less than 0.05). The cause of intracranial aneurysm has not yet been clarified. But it is well accepted that the defect of tunica media vasorum is most responsible factor as to the occurrence of intracranial aneurysms. We concluded that the genetic error of cerebral vessels including defect of media caused intracranial aneurysms, and this result was supported from the evidence that cerebrovascular anomalies showed statistically high incidence of complication of intracranial aneurysms.

  13. Probabilistic Modeling of Intracranial Pressure Effects on Optic Nerve Biomechanics (United States)

    Ethier, C. R.; Feola, Andrew J.; Raykin, Julia; Myers, Jerry G.; Nelson, Emily S.; Samuels, Brian C.


    Altered intracranial pressure (ICP) is involved/implicated in several ocular conditions: papilledema, glaucoma and Visual Impairment and Intracranial Pressure (VIIP) syndrome. The biomechanical effects of altered ICP on optic nerve head (ONH) tissues in these conditions are uncertain but likely important. We have quantified ICP-induced deformations of ONH tissues, using finite element (FE) and probabilistic modeling (Latin Hypercube Simulations (LHS)) to consider a range of tissue properties and relevant pressures.

  14. Intracranial Non-traumatic Aneurysms in Children and Adolescents


    Sorteberg, Angelika; Dahlberg, Daniel


    An intracranial aneurysm in a child or adolescent is a rare, but potentially devastating condition. As little as approximately 1200 cases are reported between 1939 and 2011, with many of the reports presenting diverting results. There is consensus, though, in that pediatric aneurysms represent a pathophysiological entity different from their adult counterparts. In children, there is a male predominance. About two-thirds of pediatric intracranial aneurysms become symptomatic with hemorrhage an...

  15. Chronic Meningitis Complicating Intracranial Hypertension in Neurobrucellosis: A Case Report. (United States)

    Tugcu, Betul; Nacaroglu, Senay Asik; Coskun, Cigdem; Kuscu, Demet Yandım; Onder, Feyza


    In neurobrucellosis, even though meningitis is encountered frequently, chronic intracranial hypertension is a rare manifestation. Early diagnosis and treatment is very important for the prevention of permanent visual loss secondary to poststasis optic atrophy in these cases. We report a case that presented with permanent visual loss secondary to intracranial hypertension in neurobrucellosis. Our goal is to draw attention to the consideration of neurobrucellosis in cases with papilla stasis, even in the absence of neurological findings in endemic areas.

    Background Differentiating melanoma metastasis from benign cutaneous lesions currently requires biopsy or costly imaging, such as positron emission tomography scans. Melanoma metastases have been observed to be subjectively warmer than similarly appearing benign lesions. We hypothesized that infrared (IR) thermography would be sensitive and specific in differentiating palpable melanoma metastases from benign lesions. Materials and methods Seventy-four patients (36 females and 38 males) had 251 palpable lesions imaged for this pilot study. Diagnosis was determined using pathologic confirmation or clinical diagnosis. Lesions were divided into size strata for analysis: 0–5, >5–15, >15–30, and >30 mm. Images were scored on a scale from −1 (colder than the surrounding tissue) to +3 (significantly hotter than the surrounding tissue). Sensitivity and specificity were calculated for each stratum. Logistical challenges were scored. Results IR imaging was able to determine the malignancy of small (0–5 mm) lesions with a sensitivity of 39% and specificity of 100%. For lesions >5–15 mm, sensitivity was 58% and specificity 98%. For lesions >15–30 mm, sensitivity was 95% and specificity 100%, and for lesions >30 mm, sensitivity was 78% and specificity 89%. The positive predictive value was 88%–100% across all strata, and the negative predictive value was 95% for >15–30 mm lesions and 80% for >30 mm lesions. Conclusions Malignant lesions >15 mm were differentiated from benign lesions with excellent sensitivity and specificity. IR imaging was well tolerated and feasible in a clinic setting. This pilot study shows promise in the use of thermography for the diagnosis of malignant melanoma with further potential as a noninvasive tool to follow tumor responses to systemic therapies.

  17. Renal Cell Carcinoma Metastasized to Pagetic Bone. (United States)

    Ramirez, Ashley; Liu, Bo; Rop, Baiywo; Edison, Michelle; Valente, Michael; Burt, Jeremy


    Paget's disease of the bone, historically known as osteitis deformans, is an uncommon disease typically affecting individuals of European descent. Patients with Paget's disease of the bone are at increased risk for primary bone neoplasms, particularly osteosarcoma. Many cases of metastatic disease to pagetic bone have been reported. However, renal cell carcinoma metastasized to pagetic bone is extremely rare. A 94-year-old male presented to the emergency department complaining of abdominal pain. A computed tomography scan of the abdomen demonstrated a large mass in the right kidney compatible with renal cell carcinoma. The patient was also noted to have Paget's disease of the pelvic bones and sacrum. Within the pagetic bone of the sacrum, there was an enhancing mass compatible with renal cell carcinoma. A subsequent biopsy of the renal lesion confirmed renal cell carcinoma. Paget's disease of the bone places the patient at an increased risk for bone neoplasms. The most commonly reported sites for malignant transformation are the femur, pelvis, and humerus. In cases of malignant transformation, osteosarcoma is the most common diagnosis. Breast, lung, and prostate carcinomas are the most common to metastasize to pagetic bone. Renal cell carcinoma associated with Paget's disease of the bone is very rare, with only one prior reported case. Malignancy in Paget's disease of the bone is uncommon with metastatic disease to pagetic bone being extremely rare. We report a patient diagnosed with concomitant renal cell carcinoma and metastatic disease within Paget's disease of the sacrum. Further research is needed to assess the true incidence of renal cell carcinoma associated with pagetic bone.

    This paper describes the imaging features of ovarian metastases from adenocarcinoma of the colon in adolescent females. We reviewed retrospectively abdominal and pelvic computed tomographic and pelvic ultrasound examinations, histologic slices, and clinical charts of six adolescent females with ovarian metastases secondary to adenocarcinoma of the colon. One patient had ovarian metastasis at presentation and was presumed to have a primary ovarian tumor. The ovarian metastases were either solid (n = 3), complex with both solid and cystic components (n = 2), or multilocular cysts (n = 1). The ovarian lesions were large, ranging from 6 cm to 18 cm in diameter. Colorectal carcinoma in adolescent females is frequently associated with ovarian metastases. One imaging characteristic differs in adult and adolescent ovarian metastases, although they do have features in common: in adolescents, a smaller proportion of colorectal ovarian metastases are multicystic (17%) compared with the adult series (45%). These lesions are frequently large and may be complex, multicystic, or solid. Although it is a rare disease, the differential dignosis of adnexal masses in adolescent females should include ovarian metastases from adenocarcinoma of the colon. (orig.)

  19. Metastases in small lymph nodes from colon cancer. (United States)

    Herrera-Ornelas, L; Justiniano, J; Castillo, N; Petrelli, N J; Stulc, J P; Mittelman, A


    Lymph node metastases are important determinants in the prognosis of primary colorectal cancer. Although it has been established that enlarged, palpable lymph nodes contain metastases in less than half of the cases, no definitive data concerning the incidence of metastases in lymph nodes measuring 5 mm or less are available. We treated the surgical specimens of 52 consecutive patients who had colon cancer with a lymph node clearance technique at the Roswell Park Memorial Institute, Buffalo. We found 2699 lymph nodes in the 52 specimens, with a mean of 52 lymph nodes per specimen (range, five to 151). Sixty-four lymph nodes were found with metastases in 21 (40%) of the 52 patients. Fifty-nine of 64 of the lymph nodes were reexamined and remeasured. Thirty-nine lymph node metastases measured less than 5 mm, 13 were between 5 and 10 mm, and eight were larger than 10 mm. We concluded that lymph node metastases in colon cancer occur most frequently in lymph nodes measuring less than 5 mm (small lymph nodes). The use of lymph node clearing techniques in surgical specimens improves detection of small lymph node metastases and thereby diminishes understaging.

    Lièvre, Astrid; Leboulleux, Sophie; Boige, Valérie; Travagli, Jean-Paul; Dromain, Clarisse; Elias, Dominique; Ducreux, Michel; Malka, David


    The prevalence of thyroid metastases in colorectal cancer (CRC) patients is unknown. We retrieved the records of all patients with CRC and pathologically proved thyroid metastasis for the period 1993-2004. Among 5,862 consecutive patients with CRC, 6 (0.1%) were diagnosed with thyroid metastases, a median of 61 months after the diagnosis of primary tumour, and a median of 19 months after the last surgical resection or radiofrequency ablation of other metastases (which were present in all cases). Signs and symptoms, when present (n=3), consisted of cervical pain, cervical adenopathy, goitre, dysphagia, and/or dysphonia. In other cases, the diagnosis was made by positron emission tomography scanning. Thyroidectomy was performed in the 5 patients with isolated thyroid metastases, with cervical lymph node dissection being required in all cases. The only patient treated conservatively because of concomitant liver and lung metastases developed life-threatening dyspnoea, which required emergent tracheal stenting. Median overall survival was 77 months, 58 months, and 12 months after the diagnosis of primary CRC, initial metastases, and thyroid metastasis, respectively. It is concluded that thyroid metastases are rare and occur late in the course of CRC. Thyroidectomy (with cervical lymph node dissection) may result in prevention or improvement of life-threatening symptoms and prolonged survival.

    Ebuzer Kalender


    Full Text Available Aim: The aim of our multicenter study is to determine retrospectively the regional distributions of distant metastases which are detected in differentiated thyroid cancers (DTC. Material and Method: Thirty-two of 960 patients with distant metastases who were given radioiodine (RAI treatment in Gaziantep University School of Medicine and Mustafa Kemal University School of Medicine were included to study. Six of patients were male, 26 of them were female. Mean age was 52±15.4. Hystopathological diagnoses were reported as papillary thyroid cancer in 23 patients and folliculary thyroid cancer in 9 patients. The distant metastasis ratio, metastasis regions and distributions were determined. Results: It was observed only lung metastasis in 18 (56.25 %, only bone metastasis in 6 (18.75 %, combination of lung and bone metastases in 3 (9.4 %, other organ metastases accompanying to bone and lung metastases in 3 (9.4 % (liver, soft tissue, mediastinum and multipl organ involvoment in 2 (6.2 % of patients. It was determined single metastasis region in 24 (75 %, 2 metastasis regions in 6 (18.75 % and multipl metastasis regions in 2 (6.25 % of patients. Discussion: Distant metastases are the biggest problem in treatment and follow-up of DTCs. It is very important to diagnosis of metastases and determine the regions of involvoment in these patients.

    Labeyrie, Paul-Emile; Braud, Florent; Gakuba, Clément; Gaberel, Thomas; Orset, Cyrille; Goulay, Romain; Emery, Evelyne; Courthéoux, Patrick; Touzé, Emmanuel


    Background Intracranial aneurysms may be associated with an underlying arteriopathy, leading to arterial wall fragility. Arterial tortuosity is a major characteristic of some connective tissue disease. Aim To determine whether intracranial aneurysm is associated with an underlying arteriopathy. Methods Using a case-control design, from May 2012 to May 2013, we selected intracranial aneurysm cases and controls from consecutive patients who had conventional cerebral angiography in our center. Cases were patients with newly diagnosed intracranial aneurysm. Controls were patients who had diagnostic cerebral angiography and free of aneurysm. The prevalence of tortuosity, retrospectively assessed according to standard definitions, was compared between cases and controls and, association between tortuosity and some aneurysm characteristics was examined, in cases only. Results About 659 arteries from 233 patients (112 cases and 121 controls) were examined. Tortuosity was found in 57 (51%) cases and 31 (26%) controls (adjusted OR = 2.71; 95%CI, 1.53-4.80). The same trend was found when looking at each tortuosity subtype (simple tortuosity, coil, kink) or at carotid or vertebral territory separately. In contrast, no association between tortuosity and rupture status, aneurysm number or neck size was found. Conclusions Cervical artery tortuosity is significantly associated with intracranial aneurysm, although not related to main aneurysm characteristics. Our results support the presence of an underlying diffuse arteriopathy in intracranial aneurysm patients.

  3. Brain metastases free survival differs between breast cancer subtypes (United States)

    Background: Brain metastases (BM) are frequently diagnosed in patients with HER-2-positive metastatic breast cancer; in addition, an increasing incidence was reported for triple-negative tumours. We aimed to compare brain metastases free survival (BMFS) of breast cancer subtypes in patients treated between 1996 until 2010. Methods: Brain metastases free survival was measured as the interval from diagnosis of extracranial breast cancer metastases until diagnosis of BM. HER-2 status was analysed by immunohistochemistry and reanalysed by fluorescent in situ hybridisation if a score of 2+ was gained. Oestrogen-receptor (ER) and progesterone-receptor (PgR) status was analysed by immunohistochemistry. Brain metastases free survival curves were estimated with the Kaplan–Meier method and compared with the log-rank test. Results: Data of 213 patients (46 luminal/124 HER-2/43 triple-negative subtype) with BM from breast cancer were available for the analysis. Brain metastases free survival differed significantly between breast cancer subtypes. Median BMFS in triple-negative tumours was 14 months (95% CI: 11.34–16.66) compared with 18 months (95% CI: 14.46–21.54) in HER-2-positive tumours (P=0.001) and 34 months (95% CI: 23.71–44.29) in luminal tumours (P=0.001), respectively. In HER-2-positive patients, co-positivity for ER and HER-2 prolonged BMFS (26 vs 15 m; P=0.033); in luminal tumours, co-expression of ER and PgR was not significantly associated with BMFS. Brain metastases free survival in patients with lung metastases was significantly shorter (17 vs 21 months; P=0.014). Conclusion: Brain metastases free survival in triple-negative breast cancer, as well as in HER-2-positive/ER-negative, is significantly shorter compared with HER-2/ER co-positive or luminal tumours, mirroring the aggressiveness of these breast cancer subtypes.

  4. Terson syndrome in conjunction with ruptured intracranial aneurysm and penetrating intracranial injury: a review of two cases. (United States)

    Rheinboldt, Matt; Francis, Kirenza; Parrish, David; Harper, Derrick; Blase, John


    Terson syndrome, the presence of intraocular hemorrhage in the setting of acutely elevated intracranial pressure, was historically described in conjunction with acute subarachnoid hemorrhage; however, more recently, it has been associated with a gamut of intracranial pathophysiology ranging from blunt or penetrating injury to neurosurgical procedures. We describe two cases of profound intracranial injury, secondary to ballistic injury, and a ruptured intracranial aneurysm, in which posterior chamber ocular hemorrhage was noted on CT imaging. Though the outcome in such cases, as with ours, is often poor, the findings are germane to clinical care as the presence of Terson syndrome has been noted to be a negative prognostic factor in multiple clinical reviews. Additionally, clinical recovery can be impacted adversely by lasting visual deficits or retinal degradation in the absence of timely ophthalmologic intervention.

  5. A Metachronous splenic metastases from esophageal cancer: a case report

    Vercelli Alessandro


    Full Text Available Abstract The spleen is an infrequent site for metastatic lesions, and solitary splenic metastases from squamous cell carcinoma of the esophagus are very rare: only 4 cases have been reported thus far. These lesions are whitish nodules that are macroscopically and radiologically similar to primary splenic lymphomas. We report a case of metachronous splenic metastases from esophageal cancer and multiple splenic abscesses, which developed nine months after apparently curative esophagectomy without adjuvant chemotherapy. The patient underwent splenectomy dissection followed by adjuvant chemotherapy, but liver and skin metastases developed, and the patient died 9 months later.

    Objective: The spine is the most common location for bone metastases. Since cure is not possible, local control and relief of symptoms is the basis for treatment, which is grounded on the use of conventional radiotherapy. Recently, spinal radiosurgery has been proposed for the local control of spinal metastases, whether as primary or salvage treatment. Consequently, we carried out a literature review in order to analyze the indications, efficacy, and safety of radiosurgery in the treatment of spinal metastases. Methods: We have reviewed the literature using the PubMed gateway with data from the Medline library on studies related to the use of radiosurgery in treatment of bone metastases in spine. The studies were reviewed by all the authors and classified as to level of evidence, using the criterion defined by Wright. Results: The indications found for radiosurgery were primary control of epidural metastases (evidence level II), myeloma (level III), and metastases known to be poor responders to conventional radiotherapy - melanoma and renal cell carcinoma (level III). Spinal radiosurgery was also proposed for salvage treatment after conventional radiotherapy (level II). There is also some evidence as to the safety and efficacy of radiosurgery in cases of extramedullar and intramedullar intradural metastatic tumors (level III) and after spinal decompression and stabilization surgery. Conclusion: Radiosurgery can be used in primary or salvage treatment of spinal metastases, improving local disease control and patient symptoms. It should also be considered as initial treatment for radioresistant tumors, such as melanoma and renal cell carcinoma. (author)

  8. Pulmonary nodules and metastases in colorectal cancer. (United States)

    Nordholm-Carstensen, Andreas


    Patients with newly diagnosed colorectal cancer (CRC) are subjected to a preoperative thoraco-abdominal CT scan to determine the cancer stage. This staging is of relevance with regard to treatment and prognosis. About 20% of the patients have distant metastatic spread at the time of diagnosis, i.e. synchronous metastases. Most common are hepatic metastases followed by pulmonary involvement. The optimal staging modality for detecting synchronous pulmonary metastases is debated. It has been argued, that synchronous pulmonary metastases (SPCM) are rare in CRC and that the consequence of detecting SPCM is minimal. Furthermore, the current staging practice is complicated by a high number of incidental findings on the thoracic CT, so-called indeterminate pulmonary nodules (IPN). IPN can potentially represent SPCM. The purpose of this thesis was to estimate the prevalence, characteristics and clinical significance of IPN and SPCM detected at the primary staging in CRC. Study I was a systematic review of published studies on IPN in CRC focusing on the prevalence and radiological characteristics of IPN proving to be malignant. This knowledge would be of value in management strategies for IPN. On average 9% of all patients staged with a thoracic CT had IPN, however, the prevalence varied significantly between patients series. This was mainly attributed to varying/lacking definitions on IPN and variable radiological expertise in the assessment of the scans. Data were too inconsistently reported in the case series for a robust statement to be made on potential radiological characteristics suggestive of malignancy in IPN. Lymph node metastasis was the most common clinicopathological finding associated with malignancy of IPN. In conclusion, one patient of every 100 scanned patients had an IPN proving to a SPCM at follow-up, but we found no evidence that IPN should result in intensified diagnostic work-up besides routine follow-up for CRC. Study II was an analysis of the

  9. Suppurative intracranial processes in 15 domestic ruminants

    Directory of Open Access Journals (Sweden)

    Antônio Carlos Lopes Câmara


    Full Text Available In addition to listeriosis which is relatively common in ruminants, there are three other uncommon suppurative intracranial processes (SIP identifiable in adult ungulates as brain abscess, basilar empyema and suppurative meningitis. The present paper reports the epidemiological, clinical, laboratorial, pathological and microbiological findings of 15 domestic ruminants with SIP. A total of 15 animals were selected (eight sheep, four cattle and three goats; with the definitive diagnoses of basilar empyema (n=3, brain abscess (n=1, listeriosis (n=5 and suppurative meningitis (n=6. Hematology revealed leukocytosis with inversion of the lymphocyte/ neutrophil ratio in 4 cases. In the majority of animals, cerebrospinal fluid (CSF presented light yellow coloration and cloudy aspect due to neutrophilic pleocytosis (15 - 997 leukocytes/µL. Microbiological culture of CSF or central nervous system (CNS fragments resulted on isolation of Trueperella (Arcanobacterium pyogenes,Listeria monocytogenes,Escherichia coli and Stenotrophomonas sp. In a goat with thalamic abscess, microbiological assay was not performed, but Gram positive bacilli type bacteria were observed in histology. The diagnosis of these outbreaks was based on the association of epidemiological, clinical, pathological and bacteriological findings; reiterating that the infectious component remains an important cause of CNS disease in domestic ruminants and also shows the need for dissemination of information about the most effective preventive measures for the ranchers.

  10. Spontaneous intracranial hypotension: a case study. (United States)

    Tyree, Tammy L; Porter, Randall


    To present an illustrative case study of a patient with spontaneous intracranial hypotension (SIH) and to increase awareness of this condition among nurse practitioners (NPs). A literature search was conducted, and deidentified patient information forms the basis of this presentation. The authors' experience and appropriate images enhance the presentation of the case study. SIH is a condition that typically occurs without a traumatic event, although it can be associated with minor trauma. It occurs when cerebrospinal fluid (CSF) leaks through a focal weakness in the dural sac or meningeal diverticula, resulting in CSF hypovolemia. Patients usually present with an orthostatic headache. The most common brain magnetic resonance imaging findings are diffuse pachymeningeal enhancement, descent of the cerebellar tonsils, and subdural fluid collections. Treatment options range from management of symptoms to surgical repair of the leak. As NPs continue to provide care in a variety of settings, including emergency departments and urgent care areas, they must be familiar with the progression of symptoms that might indicate SIH and be prepared to make appropriate referrals to prevent iatrogenic morbidity. ©2012 The Author(s) Journal compilation ©2012 American Academy of Nurse Practitioners.

  11. A retrospective study of spontaneous intracranial hemorrhage

    Directory of Open Access Journals (Sweden)

    Eka J. Wahjoepramono


    Full Text Available Spontaneous intracerebral hemorrhage (SICH is a serious disease despite progressing medical knowledge. SICH appears suddenly without warning, unlike ischemic strokes that are often preceded by a transient ischemic attack. Outcome is determined by the initial severity of the bleeding; mortality and morbidity of SICH are high. The aim of this study was to describe the characteristics of type, location, and outcome of SICH. A retrospective review was conducted on the records of 2042 cases admitted to a private hospital in Karawaci, Tangerang, between 1 January 1996 to 31 December 2008. Analysis was done on type, location, and the final outcome measures by the Glasgow Outcome Scale (GOS. The results of the study showed that the most prevalent type of SICH was hypertensive stroke, amounting to 1698 cases (83.1%, and the least commonly encountered type was dural fistula totaling  5 cases (0.3%. SICH due to hypertensive stroke frequently occurred in the basal ganglia (50.8% comprising the putamen, caudate nucleus and globus pallidus. On average, the outcome at the time of dismissal was good, where 105 cases (88.2% were GOS 4 and 5. SICH requires prompt and appropriate management. Therefore the signs and symptoms of intracranial hemorrhage should be promptly recognized and followed by appropriate ancillary examinations in order to promptly determine the management required, including possible surgical interventions.

    BACKGROUND: This paper describes histomorphologic studies on arachnoid granulations in rats, which have not been investigated in China to our knowledge.OBJECTIVE: To observe the distribution of intracranial arachnoid granulations in rats. DESIGN, TIME AND SETTING: The observational experiment was performed in the Academy of Life Sciences of Shandong Taishan Medical College from May to August 2004.MATERIALS: Thirty healthy adult Wistar rats (3-4 months old) of SPF grade, equal numbers of each sex, were selected for this study. Methylene blue parenteral solution was provided by Jiangsu Jichuan Pharmaceutical Company (China), and an optical microscope (Type: CH20; Olympus Co. Ltd., Japan) was used for observation of the histomorphology of the arachnoid granulations.METHOD: Injection of methylene blue parenteral solution into the cerebellomedullary cistern of rats.MAIN OUTCOME MEASURE: The blue stained parts of the lateral sinus were sectioned, stained by hematoxylin and eosin, and then observed under the microscope.RESULTS: The cavitas subarachnoidealis had extensive blue staining after methylene blue injection, while the arachnoid and dura were without dye accumulation. The blue dye indicated the location of the arachnoid granulations. The location of these granulations was fixed, mainly in the lateral sinus at both sides of confluence within 4 mm of the internal jugular vein.CONCLUSION: The arachnoid granulations of the rat were located mainly in the lateral sinuses of the dura mater.

  13. Potential for intracranial movements in pterosaurs. (United States)

    Prondvai, Edina; Osi, Attila


    Based on comparative anatomical, morphological, and phylogenetic considerations the potential of pterosaurs for cranial kinesis is assessed. Our investigation shows that whereas skeletally mature derived pterodactyloids have completely fused, rigid and doubtlessly akinetic skulls, skeletally immature derived pterodactyloids and more basal pterosaurs possess key features in the morphology of their otic and basal joints that are suggestive of cranial kinesis, namely streptostyly. In addition, pterosaurs exhibit an evolutionarily informative trend in the degree of cranial ossification, where it is low in most nonpterodactyloids (here named bifenestratans), intermediate in Rhamphorhynchus and Archaeopterodactyloidea, and high in derived pterodactyloids. Incomplete fusion could also indicate loose connections between skull elements. However, another crucial anatomical requirement of a kinetic skull, the permissive kinematic linkage is absent in all pterosaurian taxa. The fact, that the presence of permissive kinematic linkages in the skull is also a prerequisite of all types of cranial kinesis, provides hard evidence that all members of Pterosauria had akinetic skulls. Thus, the presence of the morphological attributes indicative of intracranial movements in some pterosaurs must be explained on grounds other than real potential for cranial kinesis. It could either be of mechanical or ontogenetic importance, or both. Alternatively, it might be considered as the morphological remnant of a real, kinetic skull possessed by the diapsid ancestors of pterosaurs.

    Abstract. Our aim was to review the MRI appearances of primary intracranial germ-cell tumours (GCT). We reviewed the MRI studies of 32 patients: 19 with germinomas, five with teratomas, one with an embryonal carcinoma, five with mixed and two with malignant nongerminomatous GCT. Eleven were in the pineal region, 12 suprasellar, five in the both sites, two in the basal ganglia and two in the corpus callosum. Contrast-enhanced images were available for 27 patients. The solid parts of GCT were nearly isointense with grey matter on both T1- and T2-weighted images. In seven patients with nongerminomatous GCT high-signal components were found on T1-weighted images, representing haemorrhage, high-protein fluid or fat. Cystic components were detected in 17 of 27 patients; eight germinomas and all nine nongerminomatous GCT had cysts. The solid components of germinomas enhanced homogeneously in eight cases and heterogeneously in 10, while all nongerminomatous GCT showed heterogeneous enhancement. MRI features tumours can facilitate correct diagnosis of GCT, including histological subtypes. (orig.)

  15. Vorticity dynamics in an intracranial aneurysm (United States)

    Le, Trung; Borazjani, Iman; Sotiropoulos, Fotis


    Direct Numerical Simulation is carried out to investigate the vortex dynamics of physiologic pulsatile flow in an intracranial aneurysm. The numerical solver is based on the CURVIB (curvilinear grid/immersed boundary method) approach developed by Ge and Sotiropoulos, J. Comp. Physics, 225 (2007) and is applied to simulate the blood flow in a grid with 8 million grid nodes. The aneurysm geometry is extracted from MRI images from common carotid artery (CCA) of a rabbit (courtesy Dr.Kallmes, Mayo Clinic). The simulation reveals the formation of a strong vortex ring at the proximal end during accelerated flow phase. The vortical structure advances toward the aneurysm dome forming a distinct inclined circular ring that connects with the proximal wall via two long streamwise vortical structures. During the reverse flow phase, the back flow results to the formation of another ring at the distal end that advances in the opposite direction toward the proximal end and interacts with the vortical structures that were created during the accelerated phase. The basic vortex formation mechanism is similar to that observed by Webster and Longmire (1998) for pulsed flow through inclined nozzles.

    Tabibian, Shadi; Motlagh, Hoda; Naderi, Majid; Dorgalaleh, Akbar


    : Intracranial hemorrhage (ICH), as a life-threatening bleeding among all kinds of congenital bleeding disorders (CBDs), is a rare manifestation except in factor XIII (FXIII) deficiency, which is accompanied by ICH, early in life, in about one-third of patients. Most inherited platelet function disorders (IPFDs) are mild to moderate bleeding disorders that can never experience a severe bleeding as in ICH; however, Glanzmann's thrombasthenia, a common and severe inherited platelet function disorder, can lead to ICH and occasional death. This bleeding feature can also be observed in grey platelet syndrome, though less frequently than in Glanzmann's thrombasthenia. In hemophilia, intracerebral hemorrhage is affected by various risk factors one of which is the severity of the disease. The precise prevalence of ICH in these patients is not clear but an estimated incidence of 3.5-4% among newborns with hemophilia is largely ascertained. Although ICH is a rare phenomenon in CBDs, it can be experienced by every patient with severe hemophilia A and B, FXIII deficiency (FXIIID), FVIID, FXD, FVD, FIID, and afibrinogenemia. Upon observing the general signs and symptoms of ICH such as vomiting, seizure, unconsciousness, and headache, appropriate replacement therapies and cranial ultrasound scans must be done to decrease ICH-related morbidity and mortality.

    Purpose: Cavitation of pulmonary metastases have been reported by several authors either as a spontaneous phenomenon or as a consequence of chemotherapy. We present two cases, with this type of image in follow-up, and 20-45 months after the end of treatment. This was the first sign of pulmonary metastases. Results: Two patients with osteogenic sarcoma developed radiological evidence of pulmonary 'bubble-like' cavitation several years following completion of chemotherapy. In one patient the 'bubble-like' cavitation transformed into a solid nodule. Both patients had surgical resections of all pulmonary lesions, and histology confirmed presence of viable osteosarcoma metastases. Conclusion: The two cases suggest that onset of 'bubble-like' cavitation in lung parenchyma of osteosarcoma patients may be the first sign of pulmonary metastases.

  2. Solitary calvarial metastases : An unusual presentation of thoracic neuroblastoma

    Directory of Open Access Journals (Sweden)

    Grover S


    Full Text Available A primary thoracic origin occurs only in 20% of neuroblastomas, and their classical presentation is mediastinal or cord compression. Skeletal metastases of neuroblastomas are characteristically multiple, and calvarial deposits usually show simultaneous involvement of orbit. Solitary metastases in neuroblastoma, is an unusual entity and its presentation as a large calvarial mass, especially from a thoracic primary, is rare. Furthermore, calvarial metastases are relatively uncommon in children compared to adults. We discuss the clinical, radiographic, CT features, and differential diagnosis of a large calvarial mass with sunray spiculation in a child, which was due to a solitary metastases from an occult thoracic neuroblastoma. The possibility of neuroblastoma presenting in this unique fashion and the importance of considering a chemosensitive tumor such as neuroblastoma in the differential diagnosis of a solitary calvarial mass in a child is highlighted by our report.

    Metastases of dedifferentiated sarcoma usually contain a dedifferentiated component. We report a rare case of dedifferentiated parosteal osteosarcoma (dd-POS) with well-differentiated multiple metastases in a 65-year-old woman with a painful firm mass on her thigh. Radiological examination revealed that the mass arose from the surface of her femur without medullary involvement. Multiple intramuscular metastases were detected in her lower leg on MR imaging. Small subcutaneous palpable masses were identified on her left lower leg, buttock, chest wall and head. An open biopsy and above-the-knee amputation were performed, and the mass on her femur was diagnosed as a dd-POS. However, histological examination on the subcutaneous lesions in her lower leg, buttock and head showed low-grade conventional POS without dedifferentiated components. To the best of our knowledge, this is the first report of a dd-POS with multiple metastases that do not contain any dedifferentiated components. (orig.)

    · AIM: To evaluate the visual findings as primary manifestations in patients with intracranial tumors.·METHODS: The medical charts of the patients with intracranial tumors who initially admitted to the Neuro-ophthalmology and Strabismus Department with ocular complaints between August 1999 and December 2012 were reviewed retrospectively. The detailed clinical history and the findings of neuro-ophthalmologic examination were recorded. Ocular symptoms and signs,the types and locations of intracranial tumors, and the duration of symptoms before the diagnosis were evaluated.·RESULTS: The mean age of 11 women(61.1%) and 7men(38.9%) was 42.2±11.0(range 20-66y) at the time of intracranial tumor diagnosis. Initial symptoms were transient visual obscurations, visual loss or visual field defect in 16 cases(88.9%), and diplopia in 2 cases(11.1%). Neuro-ophthalmologic examination revealed normal optic discs in both eyes of 6 patients(33.3%),paleness, atrophy or edema of optic disc in 12 patients(66.7%), and sixth cranial nerve palsy in 2 patients(11.1%). Visual acuity ranged between normal vision and loss of light perception. Cranial imaging demonstrated craniopharyngioma(n =1), plasmacytoma(n =1),meningioma(n =6; olfactory groove and tuberculum sellae, pontocerebellar angle, anterior cranial fossa,frontal vertex, suprasellar region), and pituitary macroadenoma(n =10). The mean duration between the onset of visual disturbances and the diagnosis of intracranial tumor was 9.8±18mo(range 3d-6y).·CONCLUSION: The ophthalmologist is frequently the first physician to encounter a patient with clinical manifestations of intracranial tumors that may cause neurological and ocular complications. Neuro-ophthalmologic findings should be carefully evaluated to avoid a delay in the diagnosis of intracranial tumors.

    Matveev, V B; Volkova, M I; Turkin, I N; Allakhverdiev, A K; Klimov, A V


    The medical records of 60 patients who underwent surgery to remove the lung metastases of T1-4N0-2 kidney cancer were retrospectively analyzed. The age of patients ranged from 31 to 70 years. Synchronous lung metastases were diagnosed in 20 (33.3%) cases, metachronous - in 40 (66.7%). 53 (88.3%) patients had lesions in one lung, and 7 (11.7%) patients--in both lungs. Solitary metastases were present in 41 (68.3%) patients, multiple--in 19 (31.7%). In 69.4% of cases, the size of lung metastases was more than 2 cm. Metastasis at other sites at the time of surgery on the lungs were present in 1 patient (supraclavicular lymph nodes). The primary tumor was removed in 56 (93.3%) of 60 patients. All 60 patients underwent removal of lung metastases (radical--53 [88.3%]). One patient underwent a radical supraclavicular lymph node dissection. All tumor lesions were removed in 50 (83.3%) patients. Median followup period was 20 (3-155) months. Perioperative complication rate was 6.6%; no deaths caused by complications of treatment were registered. Histologically, metastases of renal cell carcinoma were verified in all removed lesions from the lungs; 3 (5%) patients had mediastinal lymph node metastases. Five- and 10-year overall, specific and recurrence free survival rates were 36.3 and 19.1%, 38.9% and 27.2, 20.4 and 11.7%, respectively. Univariate analysis demonstrated an adverse effect of pN + category, bilateral pulmonary lesions, the presence of mediastinal lymph nodes metastases and non-radical removal of malignant lesions of the lung on the specific survival. Multivariate analysis confirmed a significant effect of radical surgery on the survival.

    Objective: To investigate the risk factors of bone metastases in breast carcinoma. Methods: By cross sectional study, the data of 225 breast cancer patients who were inpatients in four hospitals in Hangzhou were analyzed. All patients underwent total body bone scan with single photon emission computed tomography (SPECT) at least once during 1995 to 2000. Results: All patients were followed-up to 294 months after operation, bone metastases were found in 113 cases, suspected bone metastases 3 cases, with a bone metastases rate of 50.9% (113/222). Multivariate analysis by Cox's proportional hazards regression model showed that there were four risk factors of bone metastases in breast cancer: (1) clinical stage, I(IV stages with a hazard ratio of bone metastases of 1.945, 95% confidence interval 1.396(2.710; (2) number of invaded axillary lymph nodes, with a hazard ratio of 1.039, 95% confidence interval 1.0142(1.068; (3) skeletal complications (yes vs. no), with a hazard ratio of bone metastases of 1.722, 95% confidence interval 1.060(2.796; (4) age at the time of surgery or diagnosis, with a hazard ratio of 2.048, 95% confidence interval 1.123(3.876 for patients of age 40(50 y versus patients bellow 40 y of age and 2.837, 95% confidence interval 1.473(5.465 for patients of age above 50 y versus patients of ages between 40 and 50. Kaplan-Meier curves showed that for patients with more than 5 invasive axillary lymph nodes, compared with those with 1(5, the bone metastasis rates increased significantly ((2 =6.3319, P=0.012). Conclusion: The clinical stage, number of metastatic axillary lymph nodes, age at the time of operation and skeletal complications are essential risk factors of bone metastases.

    The presence of cutaneous metastases in squamous cell carcinomas of the head and neck (SCCHN) is rare and associated with a dismal prognosis. It is vital to distinguish these lesions from direct invasion of the skin by SCCHN or primary cutaneous malignancies as the prognosis is vastly different and so is the management. In this case report, we present four cases of cutaneous metastases and also briefly review the literature pertaining to this phenomenon.

    Full Text Available Metastases to the skeletal system are commonly observed in cancer patients, highly affecting the patients' quality of life. Imaging plays a major role in detection, follow-up, and molecular characterisation of metastatic disease. Thus, imaging techniques have been optimised and combined in a multimodal and multiparametric manner for assessment of complementary aspects in osseous metastases. This review summarises both application of the most relevant imaging techniques for bone metastasis in preclinical models and the clinical setting.

  17. Management of giant intracranial ICA aneurysms with combined extracranial-intracranial anastomosis and endovascular occlusion. (United States)

    Serbinenko, F A; Filatov, J M; Spallone, A; Tchurilov, M V; Lazarev, V A


    Nine patients with giant internal carotid artery (ICA) aneurysms (greater than 2.5 cm in diameter) were subjected to a combined extracranial-intracranial (EC-IC) bypass procedure and endovascular ICA occlusion during 1987 and 1988. The procedures were performed under one anesthetic. In all cases the collateral circulation had been judged insufficient on the basis of a strict preoperative testing protocol including: cerebral panangiography, electroencephalography, somatosensory potential recording, and cerebral blood flow monitoring during manual compression of the ICA in the neck. There were four intracavernous ICA aneurysms, four carotid-ophthalmic artery aneurysms, and one supraclinoid ICA aneurysm. All patients showed symptoms and signs of compression of the surrounding nervous structures. In the five cases of intradural lesions, the artery was occluded at the level of the aneurysm neck, so the ophthalmic artery had to be occluded. There was, nevertheless, no case of worsening of vision following surgery, and all nine patients showed significant improvement following the combined procedure. A combined EC-IC bypass procedure and endovascular ICA occlusion allows for immediate verification of the surgical results and appears to be a worthwhile method for treating giant intracranial aneurysms.

    Directory of Open Access Journals (Sweden)

    Vogl Ursula M


    Full Text Available Abstract Background In the era of cytokines, patients with brain metastases (BM from renal cell carcinoma had a significantly shorter survival than patients without. Targeted agents (TA have improved the outcome of patients with metastatic renal cell carcinoma (mRCC however, their impact on patients with BM is less clear. The aim of this analysis was to compare the outcome of patients with and without BM in the era of targeted agents. Methods Data from 114 consecutive patients who had access to targeted agent were analyzed for response rates (ORR, progression free survival (PFS and overall survival (OS. All patients diagnosed with BM underwent local, BM-specific treatment before initiation of medical treatment. Results Data of 114 consecutive patients who had access to at least one type of targeted agents were analyzed. Twelve out of 114 renal cell carcinoma (RCC patients (10.5% were diagnosed with BM. Systemic treatment consisted of sunitinib, sorafenib, temsirolimus or bevacizumab. The median PFS was 8.7 months (95% CI 5.1 - 12.3 and 11.4 months (95% CI 8.7 - 14.1 for BM-patients and non-BM-patients, respectively (p = 0.232. The median overall survival for patients with and without BM was 13.4 (95% CI 1- 43.9 and 33.3 months (95% CI 18.6 - 47.0 (p = 0.358, respectively. No patient died from cerebral disease progression. ECOG Performance status and the time from primary tumor to metastases (TDM were independent risk factors for short survival (HR 2.74, p = 0.001; HR: 0.552, p = 0.034. Conclusions Although extracerebral metastases determine the outcome of patients with BM, the benefit from targeted agents still appears to be limited when compared to patients without BM.

    Breast metastases from extramammary malignancies are uncommon. The most common sources are lymphomas/leukemias and melanomas. Some of the less common sources include carcinomas of the lung, ovary, and stomach, and infrequently, carcinoid tumors, hypernephromas, carcinomas of the liver, tonsil, pleura, pancreas, cervix, perineum, endometrium and bladder. Breast metastases from extramammary malignancies have both hematogenous and lymphatic routes. According to their routes, there are common radiological features of metastatic diseases of the breast, but the features are not specific for metastases. Typical ultrasound (US) features of hematogenous metastases include single or multiple, round to oval shaped, well-circumscribed hypoechoic masses without spiculations, calcifications, or architectural distortion; these masses are commonly located superficially in subcutaneous tissue or immediately adjacent to the breast parenchyma that is relatively rich in blood supply. Typical US features of lymphatic breast metastases include diffusely and heterogeneously increased echogenicities in subcutaneous fat and glandular tissue and a thick trabecular pattern with secondary skin thickening, lymphedema, and lymph node enlargement. However, lesions show variable US features in some cases, and differentiation of these lesions from primary breast cancer or from benign lesions is difficult. In this review, we demonstrate various US appearances of breast metastases from extramammary malignancies as typical and atypical features, based on the results of US and other imaging studies performed at our institution. Awareness of the typical and atypical imaging features of these lesions may be helpful to diagnose metastatic lesions of the breast.

    Ren, J; Xu, Y F; Kuang, T H; Chen, J; Liu, Y X


    Objective: To investigate the prognosis of osteosarcoma patients with lung metastases and its correlated factors. Methods: The clinical data of 104 osteosarcoma patients with lung metastasis from April 2007 to September 2015 were retrospectively analyzed. Univariate analysis was performed using Kaplan-Meier and Log rank test. Multivariate Cox regression was applied to analyze independent prognostic factor for patient survival. Results: The one-year, two-year and five-year survival rates of the 104 osteosarcoma patients with lung pulmonary metastasis were 93.3%, 61.5% and 11.5%, respectively, and the median survival time was 33 months. The univariate analysis revealed that number of lung metastases, objective response of first-line chemotherapy and therapeutic methods for lung metastases were significant prognostic factors for patient survival, whereas gender, age, time to lung metastasis and time to other metastasis were not (P>0.05). The multivariate analysis indicated that number of lung metastases, objective response of first-line chemotherapy and therapeutic methods for lung metastases were independent significant prognostic factors for patient survival. Conclusions: The prognosis of osteosarcoma patients with advanced lung metastases and active treatment is better. Surgery and adjuvant chemotherapy could effectively prolong survival time for osteosarcoma patients with pulmonary metastasis.

    Mori, Takeshi; Yoshioka, Masakazu; Iwatani, Kazunori; Kobayashi, Hironori; Yoshimoto, Kentaro; Nomori, Hiroaki


    Two patients with osteosarcoma lung metastases of which migrated to the parietal pleura due to contact are reported. The first patient was a 16-year-old male who had a pleural metastasis in the diaphragm within an area in contact with a single lung metastasis. Both of the tumors were resected, followed by systemic chemotherapy. Nine months after the resection of the first metastases, two other lung metastases were found which were resected after chemotherapy. The patient is alive without recurrence 84 months after the first resection of the metastases. The second patient was an 11-year-old female with a pleural metastasis of osteosarcoma which was within an area in contact with a single lung metastasis, which had been resected 4 months before. We concluded (1) that a lung metastasis of osteosarcoma occasionally metastasizes to the pleura due to contact; and (2) that because this kissing metastases of osteosarcoma could be cured by a complete resection, the intrathoracic cavity should be thoroughly observed.

  2. Brain metastases from gestational trophoblastic neoplasia: review of pertinent literature. (United States)

    Piura, E; Piura, B


    Brain metastasis from gestational trophoblastic neoplasia (GTN) is rare with about 222 cases documented in the literature and an incidence of about 11% in living GTN patients. Brain metastasis from GTN was part of a disseminated disease in 90% of patients, single metastases in the brain - 80% and located in the cerebrum - 90%. Brain metastasis was the only manifestation of metastatic GTN in 11.3% of patients, appeared synchronously with metastatic GTN in other sites of the body - 30.6% and was diagnosed from 0.3 to 60 months after diagnosis of metastatic GTN in other sites (most often in the lung) - 58.1%. Overall, 83.9% of patients with brain metastases from GTN had also lung metastases from GTN. Brain metastases from GTN showed a greater tendency to be hemorrhagic compared to brain metastases from other primaries. In patients with brain metastases from GTN, the best outcome was achieved with multimodal therapy including craniotomy, whole brain radiotherapy, and EP-EMA or EMA-CO chemotherapy. Nonetheless, brain metastasis from GTN is a grave disease with a median survival time from diagnosis of brain metastasis of about 12 months.

  3. Embolization for vertebral metastases of follicular thyroid carcinoma. (United States)

    Smit, J W; Vielvoye, G J; Goslings, B M


    The technique of selective embolization has been applied for years in the treatment of vascular anomalies, severe hemorrhage and benign or malignant tumors, notably vertebral metastases of renal cell carcinoma. Because this technique is relatively easy to perform and offers immediate relief of symptoms, it is an attractive option for patients with vertebral metastases of thyroid carcinoma with signs of spinal cord compression. In these patients, other treatment modalities like radioactive iodine, external irradiation, or surgery are more cumbersome or less effective in the short term. We describe four patients with metastasized follicular thyroid carcinoma, presenting with neurological symptoms due to vertebral metastases. All patients had undergone total thyroidectomy, ranging from 1 month to 4 yr before embolization. Embolization was combined with iodine-131 therapy when appropriate. Selective catheterization of the arteries feeding the metastases was performed, followed by infusion of polyvinyl alcohol particles (Ivalon). The procedure was technically successful in all patients without adverse effects. In the patients described, embolization resulted in rapid resolution of neurological symptoms, sometimes within hours. The therapeutic effect lasted from months to years. We conclude that embolization of vertebral metastases of follicular thyroid carcinoma is an attractive palliative therapeutic option that may offer rapid relief of symptoms.

    Full Text Available Sukirtha Tharmalingam, Edward Chow, Kristin Harris, Amanda Hird, Emily SinclairRapid Response Radiotherapy Program, Odette Cancer Centre, Sunnybrook Health Sciences Centre, University of Toronto, Toronto, CanadaAbstract: Quality of life (QOL has become an important consideration in the care of patients with bone metastases as prevalence, incidence and patient survival are on the rise. As a result, more interventional studies now measure patient’s QOL as a meaningful endpoint. However, well-developed bone metastases specific quality of life instruments are lacking. A literature review was conducted to better understand the nature of QOL instruments used in bone metastases trials. A total of 47 articles evaluating QOL in patients with bone metastases were identified. Twenty-five different instruments were used to evaluate QOL with study-designed questionnaires and the EORTC QLQ-C30 being most commonly employed. Many studies used more than one scale or instrument to measure QOL. This makes it difficult to compare QOL in bone metastases patients across studies and come to any formal conclusions. Therefore, this review demonstrates the need to develop a bone module that can be used across countries in future clinical trials.Keywords: bone metastases, quality of life, QOL instrument, review

    Background Intracranial aneurysm (IAN) is a protruding bubble or a sac on a brain artery that balloons out over time, which may lead to spontaneous subarachnoid hemorrhage (SAH), ultimately disability and mortality.Current research indicates that the disease is due to multiple causes, including environmental factors and various congenital abnormalities of blood vessels. Apart from congenital predisposition, various high-risk factors such as sex, age, hypertension, and atherosclerosis are involved in the formation of intracranial aneurysms. The aim of this study was to investigate the risk factors associated with the formation of sporadic intracranial aneurysms in Chinese Han ethnic patients.Methods A total of 251 patients with intracranial aneurysm and 338 patients with other cerebral diseases (control group) were enrolled in this study. Single factor and logistic regression model were used to analyze the association of intracranial aneurysms with age; sex; cigarette smoking; alcohol or cocaine consumption; history of hypertension, coronary artery disease, diabetes mellitus and inherited connective tissue disease; and the levels of fasting blood glucose and blood fat. The data expressed as mean ± standard deviation were processed with the statistical software SPSS13. Quantitative and qualitative data were analyzed by the independent-sample t test,and the chi-square test respectively. Logistic regression method was used to analyze the multiple factors.Results In the 251 patients, 163 (64.94%) were at age of 40 to 60 years. Sex (OR, 1.41; 95% CI, 1.01-1.96), cigarette smoking (OR, 1.81; 95% CI, 1.06-3.10), hypertension (OR, 2.32; 95% CI, 1.30-4.16) and fasting blood glucose were significantly associated with intracranial aneurysm (P<0.05). Intracranial aneurysm was correlated with alcohol consumption, coronary artery disease, and the level of blood lipids (P>0.05). Using logistic regression analysis, we identified female sex and advanced age as significant risk

  6. Irreversible Electroporation for Colorectal Liver Metastases. (United States)

    Scheffer, Hester J; Melenhorst, Marleen C A M; Echenique, Ana M; Nielsen, Karin; van Tilborg, Aukje A J M; van den Bos, Willemien; Vroomen, Laurien G P H; van den Tol, Petrousjka M P; Meijerink, Martijn R


    Image-guided tumor ablation techniques have significantly broadened the treatment possibilities for primary and secondary hepatic malignancies. A new ablation technique, irreversible electroporation (IRE), was recently added to the treatment armamentarium. As opposed to thermal ablation, cell death with IRE is primarily induced using electrical energy: electrical pulses disrupt the cellular membrane integrity, resulting in cell death while sparing the extracellular matrix of sensitive structures such as the bile ducts, blood vessels, and bowel wall. The preservation of these structures makes IRE attractive for colorectal liver metastases (CRLM) that are unsuitable for resection and thermal ablation owing to their anatomical location. This review discusses different technical and practical issues of IRE for CRLM: the indications, patient preparations, procedural steps, and different "tricks of the trade" used to improve safety and efficacy of IRE. Imaging characteristics and early efficacy results are presented. Much is still unknown about the exact mechanism of cell death and about factors playing a crucial role in the extent of cell death. At this time, IRE for CRLM should only be reserved for small tumors that are truly unsuitable for resection or thermal ablation because of abutment of the portal triad or the venous pedicles.

  7. Is neuroradiological imaging sufficient for exclusion of intracranial hypertension in children? Intracranial hypertension syndrome without evident radiological symptoms. (United States)

    Larysz, Dawid; Larysz, Patrycja; Klimczak, Andrzej; Mandera, Marek


    There are still many important questions about algorithms and clinical scenarios in the context of children with clinical intracranial hypertension symptoms (IHS) without radiological findings. Such conditions could appear in different clinical situations, including slit ventricle syndrome, overdrainage syndrome, normal volume hydrocephalus, or idiopathic intracranial hypertension. Many articles have defined specific treatment strategies for various forms of IHS, including ventriculoperitoneal shunting, medication for shunt-related migraine, steroids, and valve upgrades with antisiphoning devices or programmable systems. This study is an attempt to define the proper diagnostic procedures and treatment options for patients with various forms of IHS without evident neuroradiological findings. The authors discuss possible pathological mechanisms leading to IHS in the pediatric population. The authors present six children treated in their center. All of the children presented clinical manifestation of intracranial hypertension without evident neuroradiological findings in CT and/or MRI examinations. In three cases, the final diagnosis was slit ventricle syndrome; in two cases, normal volume hydrocephalus; in another case, idiopathic intracranial hypertension. The treatment options included short-term steroid (dexamethasone) administration and ventriculoperitoneal shunting using programmable systems. In one case of idiopathic intracranial hypertension, ICP monitoring was also performed. The authors discuss possible diagnostic and treatment strategies for the aforementioned cases. There are still many controversies about management of children with clinical symptoms of intracranial hypertension that are not confirmed in neuroimaging. It seems that our understanding of intracranial hypertension in the pediatric population is not nearly as sophisticated or complete as we might have imagined.

    The CT imaging and clinical presentation in 14 children with coexistent intracranial sepsis and sinusitis were reviewed. A routine CT head scan (10-mm thick semi-axial slices through the cranium done before and after intravenous contrast medium administration) was found to be an inadequate initial investigation as the intracranial collection was missed in four patients and the abnormal sinuses not shown in six. In half the children the dagnosis of sinusitis was unsuspected at the time of admission. The dominant clinical features were fever, intense headache and facial swelling in early adolescent males. In this clinical setting we recommend: (1) The routine scan is extended through the frontal and ethmoidal sinuses and photographed at a window level and width showing both bone detail and air/soft tissue interfaces; (2) direct coronal projections are performed through the anterior cranial fossa if no collection is seen on the routine study; (3) an early repeat scan within 48 h if the initial study shows no intracranial pathology but the fronto-ethomoidal sinuses are abnormal and there is a high clinical supicion of intracranial sepsis; and (4) in the presence of intracranial sepsis the vault is viewed at bone window settings to exclude cranial osteomyelitis.

  9. Micro packaged MEMS pressure sensor for intracranial pressure measurement (United States)

    Xiong, Liu; Yan, Yao; Jiahao, Ma; Yanhang, Zhang; Qian, Wang; Zhaohua, Zhang; Tianling, Ren


    This paper presents a micro packaged MEMS pressure sensor for intracranial pressure measurement which belongs to BioMEMS. It can be used in lumbar puncture surgery to measure intracranial pressure. Miniaturization is key for lumbar puncture surgery because the sensor must be small enough to allow it be placed in the reagent chamber of the lumbar puncture needle. The size of the sensor is decided by the size of the sensor chip and package. Our sensor chip is based on silicon piezoresistive effect and the size is 400 × 400 μm2. It is much smaller than the reported polymer intracranial pressure sensors such as liquid crystal polymer sensors. In terms of package, the traditional dual in-line package obviously could not match the size need, the minimal size of recently reported MEMS-based intracranial pressure sensors after packaging is 10 × 10 mm2. In this work, we are the first to introduce a quad flat no-lead package as the package form of piezoresistive intracranial pressure sensors, the whole size of the sensor is minimized to only 3 × 3 mm2. Considering the liquid measurement environment, the sensor is gummed and waterproof performance is tested; the sensitivity of the sensor is 0.9 × 10-2 mV/kPa.

    Full Text Available Background: Chronic otitis media is chronic inflammation of the mucoperiostial lining of the middle ear cleft. The prevalence of chronic otitis media and its intracranial complications poses a major public health problem in developing countries like India. By this study; we authors have attempted to highlight the significance of various etiological factors in the occurrence of intracranial complications due to chronic otitis media. Methods: The study was done prospectively in the department of otorhinolaryngology, J.A. group of hospitals, G. R. medical college, Gwalior during the period October 2007-2008. Thirty patients presenting to ear, nose and throat unit, diagnosed as having intracranial complications due to chronic otitis media were included in this study. Results: Most intracranial complications cases were that of meningitis. One third of the cases had past surgical history like mastoid exploration and incision and drainage of post aural abscess, and one fourth of the cases had associated extracranial complications like post aural abscess, lower motor neuron palsy, labrynthitis. Conclusion: The present study and the reference studies, both reveal that the intracranial complications of chronic otitis media are still common till date, and their signs and symptoms are often subtle until late in the course of the disease. Hence, clinicians need to maintain high index of suspicion to avoid delay in diagnosis as morbidity and mortality rates are still high, even with the advent of modern antimicrobials and aggressive surgical intervention.

  11. Cervical Myelopathy Caused by Intracranial Dural Arteriovenous Fistula (United States)

    Kim, Won Young; Kim, Jin Bum; Nam, Taek Kyun; Kim, Young Baeg


    Intracranial dural arteriovenous fistula (dAVF) usually results in various problems in the brain. But it can be presented as a myelopathy, which may make early diagnosis and management to be difficult. We recently experienced a case of cervical myelopathy caused by intracranial dAVF. A 60-year-old man presented with a 3-year history of gait disturbance due to a progressive weakness of both legs. Neurological examination revealed spastic paraparesis (grade IV) and Babinski sign on both sides. Magnetic resonance imaging showed serpentine vascular signal voids at C2-T1 on T2-weighted image with increased signal intensity and swelling of spinal cord at C1-C4. We performed a brain computed tomography angiography and found intracranial dAVF with multiple arteriovenous shunts. Venous drainages were noted at tentorial veins and cervical perimedullary veins. After Onyx embolization, the patient showed gradual improvement in motor power and gait disturbance. The venous drainage pattern is a well-known prognostic factor of dAVF. In our case, the intracranial dAVF drained to spinal perimedullary vein, which seemed to result in the ischemic myelopathy. Although it is rare condition, it sometimes can cause serious complications. Therefore, we should keep in mind the possibility of intracranial dAVF when a patient presents myelopathy. PMID:27437016

  12. Superficial siderosis is a warning sign for future intracranial hemorrhage. (United States)

    Linn, Jennifer; Wollenweber, Frank A; Lummel, Nina; Bochmann, Katja; Pfefferkorn, Thomas; Gschwendtner, Andreas; Bruckmann, Hartmut; Dichgans, Martin; Opherk, Christian


    Supratentorial superficial siderosis (SS) is a frequent imaging marker of cerebral amyloid angiopathy (CAA). It is most probably caused by focal subarachnoid hemorrhages (fSAHs). Based on single-case observations, it has been proposed that such fSAHs might be a predisposing factor for future intracranial hemorrhage. Here we tested the hypothesis if a SS as a residue of fSAHs must be regarded as a warning sign for future intracranial hemorrhage. Fifty-one consecutive patients with SS and no apparent cause other than possible or probable CAA were identified through a database search and followed-up for a median interval of 35.3 months (range 6-120 months). Main outcome measures were rate and location of new intracranial hemorrhages. Twenty-four patients (47.1 %) had experienced any new intracranial hemorrhage, 18 patients (35.3 %) had an intracerebral hemorrhage (ICH), and in 13 of them (25.5 %), the hemorrhage was located at the site of pre-existing siderosis. Six patients (11.7 %) had developed a new subarachnoid hemorrhage (SAH), four of them at the site of siderosis. Patients with SS are at substantial risk for subsequent intracranial hemorrhage. SS can be considered a warning sign of future ICH or SAH, which frequently occur adjacent to pre-existing SS. Prospective studies are needed to confirm these findings.

    Tortuous vasculature is a cause of failure of endovascular treatment of intracranial vascular lesions. We report our experience of direct cervical accesses in patients in whom the arterial femoral route was not attainable. In this retrospective study, 42 direct punctures of the carotid or the vertebral arteries at the neck were performed in 38 patients. The vessel harboring the intracranial lesion was punctured at the neck above the main tortuosity, a sheath was then positioned under fluoroscopic control to allow a stable access to the intracranial circulation. After the procedure, the sheath was removed and hemostasis was gained either by manual compression or by an arterial closure device (4 of 42, 9%). The cervical route allowed access to all intracranial lesions in all 42 procedures. A complication was encountered in six procedures (14%) related to the direct puncture. In 2 of the 42 procedures (4%), a transient vasospasm was encountered. A cervical hematoma formed in 3 of the 42 procedures (7%) after sheath withdrawal (one patient in whom an 8F sheath had been used, required surgical evacuation of a hematoma compressing the upper airways; the other patients did well without surgical evacuation). In the remaining patient (1 of 42 procedures, 2%), a small asymptomatic aneurysm at the puncture site was seen on the follow-up angiogram. Direct cervical arterial approaches to accessing the intracranial circulation is effective in patients in whom the femoral route does not allow the navigation and stabilization of guiding catheters.

  14. Surgical Management of Intracranial Neuroenteric Cysts: The UCSF Experience. (United States)

    Breshears, Jonathan D; Rutkowski, Martin J; McDermott, Michael W; Cha, Soonmee; Tihan, Tarik; Theodosopoulos, Philip V


    Objective Modern surgical experience with intracranial neuroenteric cysts is limited in the literature. We review our 15-year institutional experience with these rare lesions. Design Single-institution retrospective study. Setting Large North American tertiary care center. Participants Histologically confirmed cases of intracranial neuroenteric cyst from January 2000 to September 2014. Main Outcome Measures Pre- and postoperative modified Rankin Scale (mRS) scores, extent of resection, and postoperative complications are reported. Clinical presentation, imaging features, pathology, and operative approach are discussed. Results Five spinal and six intracranial neuroenteric cysts were surgically treated over a 15-year period. Median age at presentation for the intracranial cysts was 38.5 years. Mean cyst diameter was 3.8 cm. Five cysts were located in the pre-pontomedullary cistern, and one was located in the third ventricle. Gross total resection was achieved in four of the five posterior fossa cysts through a far lateral transcondylar approach. Postoperative complications included aseptic meningitis (one), transient abducens palsy (one), and pseudomeningocele requiring reoperation (three). Postoperative mRS scores improved to ≤1 by 6.5 months median follow-up. Conclusions Intracranial neuroenteric cysts are rare lesions with a variable imaging appearance. Complete surgical resection through a far lateral transcondylar approach is possible and usually results in symptom improvement or resolution.

    Full Text Available Background: Investigation of patients with intracranial non-traumatic hemorrhage (INH with the use of prolonged electroencephalographic (EEG monitoring allows for more effective identification of acute symptomatic seizures, subclinic epileptiform activity, local and diffuse abnormalities that are markers of brain functional activity.Aim: To increase treatment efficacy of patients with INH.Materials and methods: Thirty three patients were assessed in acute period of INH. Assessments included clinical and neurological examination, NIHSS (National Institute of Health Stroke Severity scale, GCS (Glasgow coma scale, HHS (Hunt-Hess scale; prolonged EEG monitoring with computerized tomography and/or magnetic resonance imaging of the brain. Patients received medical and surgical treatment (minimally invasive endovascular interventions or open operations, such as aneurysm clipping or wrapping/coating.Results: Twenty seven patients had open-type surgeries (among them, 23 patients had aneurysm clipping and 4, aneurysm wrapping. Two patients underwent the procedure of aneurysm embolization. Four patients were treated conservatively. According to results of prolonged pre-, peri- and postoperative EEG monitoring, most of patients had signs of disorganized electrical activity, with no regional differences, fragmented or absent alfa rhythm and diffuse polymorphic theta-activity. Marked EEG abnormalities correlated with severity registered with the assessment scales and with outcomes. During the study, epileptiform activity was registered in 1 patient, EEG comate in 3, diffuse abnormalities in 15 and local abnormalities in 14.Conclusion: The use of prolonged pre-, peri- and postoperative EEG monitoring allows for timely identification of status epilepticus, including the one without seizures. Minimally invasive interventions performed on time are associated with better prognosis in INH patients, whereas marked EEG abnormalities are associated with low scores of

    Wang, Wen-Xin; Xue, Zhe; Li, Lin; Wu, Chen; Zhang, Yan-Yang; Lou, Xin; Ma, Lin; Sun, Zheng-Hui


    Intracranial mirror aneurysms are clinically rare and uncommonly reported in the literature. Therefore, the present study evaluated a series of mirror aneurysm cases with respect to the clinical features of the patients and the treatment strategies that were used. This study retrospectively reviewed and systematically analyzed the clinical features, imaging data, treatment methods, and treatment outcomes of 68 cases of mirror aneurysms (a total of 70 pairs) in patients who were admitted to our department between November 2007 and May 2016. The patient population included 24 male and 44 female patients, with a mean age of 52 years. The mirror aneurysms were primarily located in posterior communicating artery and middle cerebral artery and 65 of the aneurysms were large or giant (≧10 mm). Of the 68 patients, 28 were treated by the clipping or embolization of all aneurysms in one stage, 16 were treated in 2 stages, 16 were treated by treating part of the aneurysms, and 8 were observed. The modified Rankin Scale scores of the 60 patients that were treated indicated that 52 had a good recovery (modified Rankin Scale score ≦2; 86.7%), and 1 patient died. Treatment strategies for mirror aneurysms should be determined individually according to the location, size, and morphology of the aneurysm, as well as the clinical manifestations of each patient. Furthermore, the responsible ruptured aneurysm should be given treatment priority, whereas the contralateral unruptured aneurysm should be observed or treated in either 1 or 2 stages.

  17. Treatment of Intracranial Aneurysms: Clipping Versus Coiling. (United States)

    Liu, Ann; Huang, Judy


    Intracranial aneurysms (IAs) have an estimated incidence of up to 10 % and can lead to serious morbidity and mortality. Because of this, the natural history of IAs has been studied extensively, with rupture rates ranging from 0.5 to 7 %, depending on aneurysm characteristics. The spectrum of presentation of IAs ranges from incidental detection to devastating subarachnoid hemorrhage. Although the gold standard imaging technique is intra-arterial digital subtraction angiography, other modalities such as computed tomography angiography (CTA) and magnetic resonance angiography (MRA) are being increasingly used for screening and treatment planning. Management of these patients depends upon a number of factors including aneurysmal, patient, institutional, and operator factors. The ultimate goal of treating patients with IAs is complete and permanent occlusion of the aneurysm sac in order to eliminate future hemorrhagic risk, while preserving or restoring the patient's neurological function. The most common treatment approaches include microsurgical clipping and endovascular coiling, and multiple studies have compared these two techniques. To date, three large prospective, randomized studies have been done: a study from Finland, International Subarachnoid Aneurysm Trial (ISAT), and the Barrow Ruptured Aneurysm Trial (BRAT). Despite differences in methodology, the results were similar: in patients undergoing coiling, although rates of rebleeding and retreatment are higher, the overall rate of poor outcomes at 12 months was significantly lower. As minimally invasive procedures and devices continue to be refined, endovascular strategies are likely to increase in popularity. However, as long-term outcome studies become available, it is increasingly apparent that they are complementary treatment strategies, with patient selection of critical importance.

    Doglietto Francesco


    Full Text Available Abstract Background Melanocytic meningeal tumours are rare extra-axial neoplasms of the nervous system, with only three reported cases in the cavernous sinus. Herein we describe for the first time the association of ocular melanosis and multiple intracranial melanocytic meningeal tumours, with the presenting lesion being in the cavernous sinus. The importance of this association is discussed together with the diagnostic and therapeutic challenges of the case. Case presentation A 20-year-old man presented with a left sixth cranial nerve deficit; general examination documented only congenital melanosis of the homolateral eye. MRI examination showed a space occupying lesion in the left cavernous sinus, which was followed conservatively for 2 years, until a new space occupying lesion was evident at the level of the right frontal convexity: both lesions presented with neuroradiological characteristics suggestive of melanin content. The frontal convexity lesion was removed: intraoperatively the dura was markedly and diffusely melanotic. Histological examination documented a melanocytic meningeal tumour, with a proliferative index of 3 %. The patient underwent 3D-Conformal Radiation Therapy on the lesion of the cavernous sinus (total dose 5040 cGy, with initial tumour reduction. Three years later, due to a symptomatic growth, he underwent partial removal of the lesion in the cavernous sinus. Histological examination was unchanged. He then received adjuvant Temozolomide with Low Dose Fractionated Radiation Therapy (LD-FRT. Due to further disease progression cisplatin plus fotemustine were administered, concomitant with LD-FRT: after two cycles MRI documented significant disease regression. After a period of apparent disease control, the patient presented with persistent cough and evidence of multiple thoracic metastases, which lead to his death, seven years after presentation. Conclusions Intracranial melanocytic meningeal tumours are challenging

    Full Text Available INTRODUCTION: Breast cancer brain metastases (BCBM are a challenging consequence of advanced BC. Nanoparticle agents, including liposomes, have shown enhanced delivery to solid tumors and brain. We compared pharmacokinetics (PK and efficacy of PEGylated liposomal doxorubicin (PLD with non-liposomal doxorubicin (NonL-doxo in an intracranial model of BC. METHODS: Athymic mice were inoculated intracerebrally with MDA-MB-231-BR-luciferase-expressing cells. Tumor-bearing mice were administered PLD or NonL-doxo at 6 mg/kg IV × 1 and were euthanized prior to and 0.083, 1, 3, 6, 24, 72 and 96 h post-treatment. Samples were processed to measure sum total doxorubicin via HPLC. PLD and NonL-doxo were administered IV weekly as single agents (6 mg/kg or in combination (4.5 mg/kg with the PARP inhibitor, ABT-888, PO 25 mg/kg/day. Efficacy was assessed by survival and bioluminescence. RESULTS: Treatment with PLD resulted in approximately 1,500-fold higher plasma and 20-fold higher intracranial tumor sum total doxorubicin AUC compared with NonL-doxo. PLD was detected at 96 h; NonL-doxo was undetectable after 24 h in plasma and tumor. Median survival of PLD-treated animals was 32 days (d, [CI] 31-38, which was significantly longer than controls (26d [CI 25-28]; p = 0.0012 or NonL-doxo treatment (23.5d [CI 18-28], p = 0.0002. Combination treatment with PLD/ABT-888 yielded improved survival compared to NonL-doxo/ABT-888 (35d [CI 31-38] versus 29.5d [CI 25-34]; p = 0.006. CONCLUSIONS: PLD provides both PK and efficacy advantage over NonL-doxo in the treatment of an in vivo model of BCBM. The results provide preclinical rationale to translate findings into early phase trials of PLD, with or without ABT-888, for patients with BCBM.

  1. Intracranial Hypotension Syndrome, Diagnosis and Treatment in Radiology Clinics

    Directory of Open Access Journals (Sweden)

    S. Albayram


    Full Text Available Introduction & Background: Only 12 years ago the first report on pachymeningeal gadolinium enhance-ment in low-pressure headaches appeared in the lit-erature. Intracranial hypotension is a result of low CSF volume caused by either spontaneous or postoperative leakage. The syndrome has been reported to occur after head trauma, a tear in a spinal nerve root sheath, perineural cyst, or spinal arachnoid diverticulum. Iatrogenic causes include lumbar puncture or overdraining ventricular or spinal shunts. Spontaneous intracranial hypotension is thought to result from rupture of a spinal arachnoid membrane that allows CSF passage into the subdural or epidural space. It is typically not attributable to a major traumatic event or prior diagnostic or therapeutic intervention; however, intracranial hypotension may be associated with a history of minor trauma such as sports activities or severe coughing. Diffuse pachymeningeal enhancement is thought to reflect the Monro-Kellie rule, which describes the inverse relationship of CSF volume and intracranial blood volume within the rigid confines of the skull. This reflex mechanism protects nervous tissue by maintaining a constant buffer (ie, blood or CSF subjacent to its bony covering. Though this principle was described for intracranial processes and helps to explain the reason for intracranial pachymeningeal enhancement, it can also be applied to the bony spinal canal. Explaining pachymeningeal enhancement in the spine becomes more difficult because the hypervascular outer dural layer covering the brain does not extend to cover the spine, and the single layer of dura that does cover the spine is relatively avascular. Perhaps reports of pachymeningeal enhancement along the spinal canal in intracranial hypotension more accurately reflect prominent epidural venous engorgement. In all cases of intracranial hypotension reported in the literature, patients presented with headaches. These headaches are typically

    In contrast to typical astrocytic tumors that show hypodense areas on computed tomographic images, some intracranial tumors show hyperdense areas on CT images. The major reasons for hyperdensity on CT images are hypercellular lesions, intratumoral calcification, and intratumoral hemorrhage. Malignant lymphomas, germinomas, and medulloblastomas show homogenous hyperdensity on CT images because of their hypercellularity. Tumorous lesions such as subependymal giant cell astrocytomas, oligodendrogliomas, ependymomas, central neurocytomas, craniopharyngiomas, and meningiomas often present with hyperdense calcified lesions on CT images. Intratumoral hemorrhage also causes hyperdensity on CT images, and is often associated with metastatic brain tumors, glioblastomas, pituitary adenomas, and rarely with any of the other intracranial tumors. Although magnetic resonance imaging is now the major diagnostic tool for diseases of the central nervous system, the first imaging studies for patients with neurologic symptoms are still CT scans. Hyperdense areas on CT images are a clue to making an accurate diagnosis of intracranial neoplasms. (author)

  3. Intracranial hemorrhage revealing pseudohypoparathyroidism as a cause of fahr syndrome. (United States)

    Swami, Abhijit; Kar, Giridhari


    Pseudohypoparathyroidism is an infrequently encountered disease. It is one of the causes of Fahr syndrome which also is a rare clinical entity caused by multiple diseases. A 4-year-old man hospitalized for sudden onset left hemiparesis and hypertension was diagnosed to have right thalamic and midbrain hemorrhage on plain CT scan of the head which also revealed co-existent extensive intracranial calcifications involving the basal ganglia and cerebellum bilaterally. General physical examination revealed features of Albright hereditary osteodystrophy, goitre, hypertension, left hemiparesis, and signs of cerebellar dysfunction. Laboratory findings suggested hypocalcemia, hyperphosphatemia along with high TSH, low FT(4), low FT(3), and high anti-TPO antibody. Though bilateral intracranial calcifications are usually encountered as an incidental radiological finding in the CT scan of brain, in this case, the patient admitted for thalamic and midbrain hemorrhage was on investigation for associated intracranial calcification, and goitre was also found to have coexisting pseudohypoparathyroidism and autoimmune hypothyroidism.

    Olson, DaiWai M; Lewis, Lisa S; Bader, Mary Kay; Bautista, Cynthia; Malloy, Rachel; Riemen, Kristina E; McNett, Molly M


    The purpose of this study was to describe nursing practice in the care of patients with intracranial pressure monitoring. Although standards for care of such patients have been established, there continue to be variations in the nursing practice. This was an observational study in which data were collected from 28 nurse-patient dyads at 16 different hospitals across the United States. Each dyad was observed for 2 hours; nursing actions and patient responses including intracranial pressure readings were documented. Differences in the care of patients with intracranial pressure monitoring were prevalent. Variations in practice were prompted by healthcare provider prescriptions as well as nursing decisions. Prescriptions and interventions were often not supported by the available scientific evidence. For more insights from the authors, see Supplemental Digital Content 1, at

  5. Intracranial hemorrhages and late hemorrhagic disease associated cholestatic liver disease. (United States)

    Per, Hüseyin; Arslan, Duran; Gümüş, Hakan; Coskun, Abdulhakim; Kumandaş, Sefer


    Deficiency of vitamin K predisposes to early, classic or late hemorrhagic disease of the newborn (HDN); of which late HDN may be associated with serious and life-threatening intracranial hemorrhage. Late HDN is characterized intracranial bleeding in infants aged 1 week to 6 months due to severe vitamin K deficiency. Late HDN is still an important cause of mortality and morbidity in developing countries where vitamin K prophylaxis is not routinely practiced. Children with cholestatic liver disease are at risk for developing secondary vitamin K deficiency because of fat malabsorbtion and inadequate dietary intake. In this study, we described 11 infants with cholestatic liver disease with different etiologies exhibiting intracranial hemorrhage (ICH). Six patients underwent surgical evacuation of ICH, following the administration of vitamin K and/or fresh frozen plasma. The possibility of cholestatic liver disease should be considered in the treatment of ICH due to vitamin K deficiency.

  6. Proximal Limb Weakness Reverting After CSF Diversion In Intracranial Hypertension

    Directory of Open Access Journals (Sweden)

    Sinha S


    Full Text Available We report about two young girls who developed progressive visual failure secondary to increased intracranial pressure and had significant proximal muscle weakness of limbs. Patients with elevated intracranial pressure (ICP may present with "false localizing signs", besides having headache, vomiting and papilledema. Radicular pain as a manifestation of raised ICP is rare and motor weakness attributable to polyradiculopathy is exceptional. Two patients with increased intracranial pressure without lateralizing signs′ had singnificant muscle weakness. Clinical evaluation and laboratory tests did not disclose any other cause for weakness. Following theco-peritoneal shunt, in both patients, there was variable recovery of vision but the proximal weakness and symptoms of elevated ICP improved rapidly. Recognition of this uncommon manifestation of raised ICP may obviate the need for unnecessary investigation and reduce morbidity due to weakness by CSF diversion procedure.

  7. Intracranial hemorrhage in late hemorrhagic disease of the newborn. (United States)

    Pooni, Puneet A; Singh, Daljit; Singh, Harmesh; Jain, B K


    This study was conducted to evaluate the clinical profile and outcome in late hemorrhagic disease of the newborn (HDN) with particular reference to intracranial hemorrhage. Infants (n = 42) presenting with late HDN from January 1998 to December 2001 were studied. Majority (76%) were in the age group of 1-3 months. All were term babies on exclusive breast-feeding and none received vitamin K at birth. 71% patients presented with intracranial hemorrhage, commonest site being intracerebral and multiple ICH. Visible external bleeding was noted in 1/3rd of patients only. Three patients expired. Late HDN is still an important cause of mortality and morbidity in developing countries where vitamin K prophylaxis is not routinely practiced. Isolated intracranial hemorrhage is a common mode of presentation.

  8. Intracranial hemorrhage due to late hemorrhagic disease in two siblings. (United States)

    Per, Hüseyin; Kumandaş, Sefer; Ozdemir, Mehmet Akif; Gümüş, Hakan; Karakukcu, Musa


    Deficiency of vitamin K predisposes to early, classic or late hemorrhagic disease of the newborn (HDN); late HDN may be associated with serious and life-threatening intracranial hemorrhage. Late HDN is characterized by intracranial bleeding in infants aged 1 week to 6 months due to severe vitamin K deficiency, occurring particularly in exclusively breastfed infants. Late HDN is still an important cause of mortality and morbidity in developing countries where vitamin K prophylaxis is not routinely practiced. In this study, we report on two siblings with intracranial bleeding who were fully breastfed without a routine supplementation of vitamin K. Vitamin K should be given to all newborns as a single, intramuscular dose of 1 mg.

  9. Intracranial extradural hematoma: Spontaneous rapid decompression - not resolution

    Directory of Open Access Journals (Sweden)

    Abdul Rashid Bhat


    Full Text Available The surgical option to evacuate an intracranial extradural hematoma (EDH was postponed in a 2-year-old female child who appeared fully alert and active after a brief spell of unconsciousness following a fall from height. The child was received, with a swelling on and around the right parietal eminence, by the emergency staff just half an hour after the time of injury. The immediate X-ray skull and first computed tomography (CT scan head showed a parietal bone fracture, EDH, and cephalhematoma. However, follow-up CT scan head after about 4΍ h revealed the dramatic absence of EDH but increased size and bogginess of cephalhematoma. The EDH had transported into subgaleal space resulting in a decompression of intracranial compartment in <5 h, thereby preventing surgical intervention but necessitating monitoring, though there was no back flow intracranially.

  10. Noninvasive Intracranial Volume and Pressure Measurements Using Ultrasound (United States)

    Hargens, A. R.


    Prevention of secondary brain injuries following head can be accomplished most easily when intracranial pressure (ICP) is monitored. However, current measurement techniques are invasive and thus not practical in the combat environment. The Pulsed Phase Lock Loop (PPLL) devise, which was developed and patented, uses a unique, noninvasive ultrasonic phase comparison method to measure slight changes in cranial volume which occur with changes in ICP. Year one studies involved instrument improvements and measurement of altered intracranial distance with altered ICP in fresh cadavera. Our software was improved to facilitate future studies of normal subjects and trauma patients. Our bench studies proved that PPLL output correlated highly with changes in path length across a model cranium. Cadaveric studies demonstrated excellent compact, noninvasive devise for monitoring changes in intracranial distance may aid in the early detection of elevated ICP, decreasing risk of secondary brain injury and infection, and returning head-injured patients to duty.

  11. Intracranial Hemorrhage Revealing Pseudohypoparathyroidism as a Cause of Fahr Syndrome

    Directory of Open Access Journals (Sweden)

    Abhijit Swami


    Full Text Available Pseudohypoparathyroidism is an infrequently encountered disease. It is one of the causes of Fahr syndrome which also is a rare clinical entity caused by multiple diseases. A 4-year-old man hospitalized for sudden onset left hemiparesis and hypertension was diagnosed to have right thalamic and midbrain hemorrhage on plain CT scan of the head which also revealed co-existent extensive intracranial calcifications involving the basal ganglia and cerebellum bilaterally. General physical examination revealed features of Albright hereditary osteodystrophy, goitre, hypertension, left hemiparesis, and signs of cerebellar dysfunction. Laboratory findings suggested hypocalcemia, hyperphosphatemia along with high TSH, low FT4, low FT3, and high anti-TPO antibody. Though bilateral intracranial calcifications are usually encountered as an incidental radiological finding in the CT scan of brain, in this case, the patient admitted for thalamic and midbrain hemorrhage was on investigation for associated intracranial calcification, and goitre was also found to have coexisting pseudohypoparathyroidism and autoimmune hypothyroidism.

  12. Primary varicella infection presenting with headache and elevated intracranial pressure. (United States)

    Gilad, Oded; Shefer-Averbuch, Noa; Garty, Ben Zion


    Primary varicella infection may be associated with neurologic complications, such as cerebritis and meningoencephalitis. Several cases of varicella infection with elevated intracranial pressure have been reported. We describe a 13-year-old immunocompetent girl who presented with a clinical picture of headaches and elevated intracranial pressure as the only manifestation of primary varicella zoster infection. The working diagnosis at first was pseudotumor cerebri based on complaints of headache of 2 weeks' duration, in addition to vomiting and papilledema, without fever or skin eruption. On lumbar puncture, opening pressure was 420 mmH2O, but mild pleocytosis and mildly elevated protein level ruled out the diagnosis of pseudotumor cerebri. Our patient had no history of previous varicella infection, and she did not receive the varicella zoster vaccine. Serology tests, done on admission and repeated 2 months later, suggested primary varicella infection. The literature on varicella infection associated with pseudotumor cerebri or elevated intracranial pressure is reviewed.

  13. [Intracranial epidural abscess in a newborn secondary to skin catheter]. (United States)

    Fernández, L M; Domínguez, J; Callejón, A; López, S; Pérez-Avila, A; Martín, V


    Intracranial epidural abscesses are uncommon lesions, being more frequents in older children and adults. They commonly arise as a result of direct extension of a preexisting infection and rarely present with focal deficit. We present a case of a 11-days old preterm infant who developed an intracranial epidural abscess as a result of an infected scalp vein catheter. The diagnosis was made on the basis of the cranial ultrasound and CT scan images. An identified strain of Enterococcus faecium was cultured from all the samples. The patient underwent a right frontal craniotomy with drainage of the abscess and a 2-week total course of intravenous antibiotics was administrated. CT scan imaging 3 week after the procedure demonstrated no evidence of residual lesion. When present, a scalp vein catheter, in absence of others predisponing factors, must be considered as an etiologic agent for an intracranial epidural abscess in this age-group.

W.; Howard, Ted; Lee, Emonuel


    In this review of a collected series of patients undergoing hepatic resection for colorectal metastases, 100 patients were found to have survived greater than five years from the time of resection. Of these 100 long-term survivors, 71 remain disease-free through the last follow-up, 19 recurred prior to five years, and ten recurred after five years. Patient characteristics that may have contributed to survival were examined. Procedures performed included five trisegmentectomies, 32 lobectomies, 16 left lateral segmentectomies, and 45 wedge resections. The margin of resection was recorded in 27 patients, one of whom had a positive margin, nine of whom had a less than or equal to l-cm margin, and 17 of whom had a greater than 1-cm margin. Eighty-one patients had a solitary metastasis to the liver, 11 patients had two metastases, one patient had three metastases, and four patients had four metastases. Thirty patients had Stage C primary carcinoma, 40 had Stage B primary carcinoma, and one had Stage A primary carcinoma. The disease-free interval from the time of colon resection to the time of liver resection was less than one year in 65 patients, and greater than one year in 34 patients. Three patients had bilobar metastases. Four of the patients had extrahepatic disease resected simultaneously with the liver resection. Though several contraindications to hepatic resection have been proposed in the past, five-year survival has been found in patients with extrahepatic disease resected simultaneously, patients with bilobar metastases, patients with multiple metastases, and patients with positive margins. Five-year disease-free survivors are also present in each of these subsets. It is concluded that five-year survival is possible in the presence of reported contraindications to resection, and therefore that the decision to resect the liver must be individualized.

  15. Histopathological analysis of 177 cases with operated intracranial meningioma

    Directory of Open Access Journals (Sweden)

    Guner Menekse


    Full Text Available Purpose: Aim of this study is to evaluate histopathologic properties of patients with intracranial meningioma who were operated due to intracranial mass. Method: 177 cases diagnosed with intracranial meningioma were retrospectively examined in our clinic between the years of 2007-2012 and their age, sex, tumor localization, and histopathologic properties were analyzed. Results: 74.6% of 177 intracranial meningioma cases were females, 25.4% were males and the ratio of Male/Female was found 3.4/10. The age interval of the cases was between 12-105 years old. It was most frequently seen at the interval of 51-60. In histopathologic examination, 163 cases (92.1% were noted as WHO Grade I, 11 cases (6.2% were WHO Grade II, and 3 cases (1.7% were WHO Grade III. While meningotelial transitional, and psammomatous type was the most frequently seen in WHO Grade I, atypical meningioma was only dominant in Grade II. In WHO Grade II and III cases, dominance of the male sex was present. While 88.1% of the cases had supratentorial localization, 11.9% had infratentorial localization, 1 case had lateral ventricle localization. In 7 cases (3.9% of the series, multiple meningiomas were determined. Conclusion: In a series of 177 cases, intracranial meningiomas were seen between 51-60 years old and its most frequent localization was convexity. While Grade I cases were seen in the female sex, dominance of the male sex was present in Grade II and III cases. Additionally, all of multiple meningiomas detected were female cases. Meningotelial meningiomas constitute the most commonly seen subtype among Grade I cases. Key Words: Intracranial meningioma, histopathological classification, clinical study [Cukurova Med J 2013; 38(1.000: 41-59

  16. Progressive versus Nonprogressive Intracranial Dural Arteriovenous Fistulas: Characteristics and Outcomes. (United States)

    Hetts, S W; Tsai, T; Cooke, D L; Amans, M R; Settecase, F; Moftakhar, P; Dowd, C F; Higashida, R T; Lawton, M T; Halbach, V V


    A minority of intracranial dural arteriovenous fistulas progress with time. We sought to determine features that predict progression and define outcomes of patients with progressive dural arteriovenous fistulas. We performed a retrospective imaging and clinical record review of patients with intracranial dural arteriovenous fistula evaluated at our hospital. Of 579 patients with intracranial dural arteriovenous fistulas, 545 had 1 fistula (mean age, 45 ± 23 years) and 34 (5.9%) had enlarging, de novo, multiple, or recurrent fistulas (mean age, 53 ± 20 years; P = .11). Among these 34 patients, 19 had progressive dural arteriovenous fistulas with de novo fistulas or fistula enlargement with time (mean age, 36 ± 25 years; progressive group) and 15 had multiple or recurrent but nonprogressive fistulas (mean age, 57 ± 13 years; P = .0059, nonprogressive group). Whereas all 6 children had fistula progression, only 13/28 adults (P = .020) progressed. Angioarchitectural correlates to chronically elevated intracranial venous pressures, including venous sinus dilation (41% versus 7%, P = .045) and pseudophlebitic cortical venous pattern (P = .048), were more common in patients with progressive disease than in those without progression. Patients with progressive disease received more treatments than those without progression (median, 5 versus 3; P = .0068), but as a group, they did not demonstrate worse clinical outcomes (median mRS, 1 and 1; P = .39). However, 3 young patients died from intracranial venous hypertension and intracranial hemorrhage related to progression of their fistulas despite extensive endovascular, surgical, and radiosurgical treatments. Few patients with dural arteriovenous fistulas follow an aggressive, progressive clinical course despite treatment. Younger age at initial presentation and angioarchitectural correlates to venous hypertension may help identify these patients prospectively. © 2015 by American Journal of Neuroradiology.

  17. Nocturnal carbon dioxide monitoring in patients with idiopathic intracranial hypertension. (United States)

    Abraham, Alon; Peled, Nir; Khlebtovsky, Alexander; Benninger, Felix; Steiner, Israel; Stiebel-Kalish, Hadas; Djaldetti, Ruth


    Idiopathic intracranial hypertension may be associated with sleep apnea. This study evaluated the incidence of sleep breathing disorders in patients with idiopathic intracranial hypertension. Overnight respiratory monitoring was performed in 22 untreated patients with idiopathic intracranial pressure diagnosed at a tertiary medical center over a two-year period and 12 sex- and age-matched control subjects. Breathing measures included heart rate, respiratory rate,oxygen saturation, and continuous end-tidal capnography. Sleep quality and daily fatigue were assessed by self-report questionnaires. Mean age of the study group was 32.6±12.2 years and of the control group, 37.0±12.9 years. Neither group had significant findings of hypoxia or hypercarbia during sleep, and there were no between-group differences in mean carbon dioxide level (patients, 35.8±4.41 mmHg; controls, 37.6±4.38 mmHg; p>0.02) or minimal oxygen saturation (96.35±1.99% and 5.69±1.71%, respectively; p>0.02). The study group had significantly more events of apnea (CO2) per hour of sleep than the control group (1.21±1.38 and 0.92±0.56, respectively; p=0.02), although values were still within normal range (<5/hr). Idiopathic intracranial hypertension is not associated with a clinically significant nocturnal breathing abnormality, and hypercarbia is apparently not involved in the pathogenesis. However, it is possible that a subtle increase in paroxysmal sleep apnea (CO2) events might be sufficient to cause vasodilatation of the cerebral blood vessels, thereby increasing intracranial pressure. Screening for sleep apnea may be appropriate in idiopathic intracranial hypertension patients, and further studies are needed to clarify this issue. Copyright © 2013 Elsevier B.V.

  18. Systematic review and case report: Intracranial complications of pediatric sinusitis. (United States)

    Patel, Neha A; Garber, David; Hu, Shirley; Kamat, Ameet


    Intracranial complications of rhinosinusitis are rare in the post-antibiotic era. However, due to potentially devastating outcomes, prompt recognition and management are essential. This study aims to perform the first systematic review of the intracranial complications of rhinosinusitis in order to better characterize their clinical presentation, diagnosis, and treatment, and report a case of frontal lobe empyema secondary to pediatric frontoethmoid sinusitis. Ovid MEDLINE, Cochrane Library, and Google Scholar. Full-text, peer-reviewed journal publications from 1947 to January 1, 2015 in English; focus on intracranial complications of sinusitis; pediatric patients (<18 years of age); studies including data on diagnostic workup and treatment. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Sixteen studies involving 180 patients were included. An overwhelming majority of patients were young adolescent males (70%). The most common intracranial complications were subdural empyema (49%), epidural abscess (36%), cerebral abscess (21%), and meningitis (10%). Patients most often presented with nonspecific symptoms such as headache, fever, nausea and vomiting. Computed tomography with contrast or magnetic resonance imaging confirmed the diagnosis when intracranial complications were suspected. Typical treatment included surgical incision and drainage, often involving joint neurosurgical and otolaryngological procedures, combined with a long course of antibiotics. The morbidity rate was 27%, and the mortality rate was 3.3%. All studies were retrospective chart reviews, case series or case reports. A review of the currently available literature shows that with a high degree of suspicion, multidisciplinary cooperation and aggressive treatment, favorable outcomes are attainable. The most effective surgical treatment for intracranial complications remains unclear and should be investigated further. Copyright © 2016 Elsevier Ireland Ltd. All rights

  19. Predicting metastasized seminoma using gene expression. (United States)

    Ruf, Christian G; Linbecker, Michael; Port, Matthias; Riecke, Armin; Schmelz, Hans U; Wagner, Walter; Meineke, Victor; Abend, Michael


    Treatment options for testis cancer depend on the histological subtype as well as on the clinical stage. An accurate staging is essential for correct treatment. The 'golden standard' for staging purposes is CT, but occult metastasis cannot be detected with this method. Currently, parameters such as primary tumour size, vessel invasion or invasion of the rete testis are used for predicting occult metastasis. Last year the association of these parameters with metastasis could not be validated in a new independent cohort. Gene expression analysis in testis cancer allowed discrimination between the different histological subtypes (seminoma and non-seminoma) as well as testis cancer and normal testis tissue. In a two-stage study design we (i) screened the whole genome (using human whole genome microarrays) for candidate genes associated with the metastatic stage in seminoma and (ii) validated and quantified gene expression of our candidate genes (real-time quantitative polymerase chain reaction) on another independent group. Gene expression measurements of two of our candidate genes (dopamine receptor D1 [DRD1] and family with sequence similarity 71, member F2 [FAM71F2]) examined in primary testis cancers made it possible to discriminate the metastasis status in seminoma. The discriminative ability of the genes exceeded the predictive significance of currently used histological/pathological parameters. Based on gene expression analysis the present study provides suggestions for improved individual decision making either in favour of early adjuvant therapy or increased surveillance. To evaluate the usefulness of gene expression profiling for predicting metastatic status in testicular seminoma at the time of first diagnosis compared with established clinical and pathological parameters. Total RNA was isolated from testicular tumours of metastasized patients (12 patients, clinical stage IIa-III), non-metastasized patients (40, clinical stage I) and adjacent 'normal' tissue

  6. Fast virtual stenting with deformable meshes: application to intracranial aneurysms. (United States)

    Larrabide, Ignacio; Radaelli, Alessandro; Frangi, Alejandro


    Intracranial stents are medical devices that are becoming increasingly popular in the treatment of intracranial aneurysms. A methodology that predicts the released stent configuration prior to intervention has the potential to support the physician in the selection of the optimal approach for a specific patient. This paper proposes a fast virtual stenting technique based on constrained simplex deformable models that is able to virtually release stents in arbitrarily shaped vessel and aneurysm models. The technique effectively embeds the geometrical properties of the stent (cell design, strut size and shape and angles between struts) and achieves favorable execution times of the order of one minute.

    Ogbonnaya, Ebere Sunny


    Spinal dural arterio-venous fistula (DAVF) is rare and usually involves the thoracic segments. The classical presentation is a slowly progressive ataxia. Clinical presentation of intracranial DAVF depends on the site of the DAVF, as well as the vessels involved. Patients may present with pulsatile tinnitus, occipital bruit, headache, dementia, visual impairment as well as neurological deterioration distant from the DAVF as a result of venous hypertension and cortical haemorrhage. The authors present a rare case of progressive myelopathy secondary to an intracranial DAVF.

  10. Harmonics tracking of intracranial and arterial blood pressure waves. (United States)

    Shahsavari, Sima; McKelvey, Tomas


    Considering cardiorespiratory interaction and heart rate variability, a new approach is proposed to decompose intracranial pressure and arterial blood pressure to their different harmonics. The method is based on tracking the amplitudes of the harmonics by a Kalman filter based tracking algorithm. The algorithm takes benefit of combined frequency estimation technique which uses both Fast Fourier Transform and RR-interval detection. The result would be of use in intracranial pressure and arterial blood pressure waveform analysis as well as other investigations which need to estimate contribution of specific harmonic in above mentioned signals such as Pressure-Volume Compensatory Reserve assessment.

    Peral Cagigal, Beatriz; Barrientos Lezcano, Javier; Floriano Blanco, Raúl; García Cantera, José Miguel; Sánchez Cuéllar, Luis Antonio; Verrier Hernández, Alberto


    Frontal sinus mucoceles can present with a multitude of different symptoms including ophthalmic disturbances. Even benign, they have a tendency to expand by eroding the surrounding bony walls that displaces and destroys structures by pressure and bony resorption. A 32-year-old man with diplopia, proptosis of the right eye and headache was presented. The diagnosis was frontal sinus mucocele with intracranial and intraorbital extension. Possible clinical manifestations of mucoceles, diagnostic imaging techniques and treatment used are discussed. Frontal mucoceles are benign and curable, early recognition and management of them is of paramount importance, because they can cause local, orbital or intracranial complications.

    Naseer A Choh


    Full Text Available Intracranial neurenteric cysts are exceedingly rare congenital intracranial lesions that result from disorder of gastrulation. Still, more rarely, the cyst contents may leak into the CSF and give rise to recurrent episodes of chemical meningitis. We present a case of chemical meningitis due to a leaking posterior fossa neurenteric cyst in a young female, with emphasis on its imaging features. The final diagnosis was achieved by sufficiently characteristic imaging features; histopathologic documentation could not be achieved as the patient denied surgery.

  13. Desflurane increases intracranial pressure more and sevoflurane less than isoflurane in pigs subjected to intracranial hypertension. (United States)

    Holmström, Anders; Akeson, J


    Desflurane and sevoflurane may have advantages over isoflurane in neuroanesthesia, but this is still under debate. A porcine model with experimental intracranial hypertension was used for paired comparison of desflurane, sevoflurane, and isoflurane with respect to the effects on cerebral blood flow (CBF), cerebrovascular resistance (CVR), and intracranial pressure (ICP). The agents, given in sequence to each of six pigs, were compared at 0.5 and 1.0 minimal alveolar concentrations (MAC) and three mean arterial blood pressure (MAP) levels (50, 70, and 90 mm Hg) at normocapnia and one MAP level (70 mm Hg) at hypocapnia. MAC for each agent had been previously determined in a standardized manner for comparison reliability. CBF was measured with Xe. MAP was lowered by inflation of a balloon catheter in the inferior caval vein and raised by inflation of a balloon catheter in the descending aorta. ICP was measured intraparenchymally. Two Fogarty catheters positioned extradurally were inflated to a baseline ICP of 20 to 22 mm Hg at 0.2 MAC of each agent. CBF and ICP with the three agents at normocapnia and MAP 70 and 90 mm Hg at both 0.5 and 1.0 MAC were as follows (P isoflurane > sevoflurane. None of the agents abolished CO2 reactivity. High-dose desflurane resulted in a higher CBF at hypocapnia than corresponding doses of sevoflurane or isoflurane, but there were no significant differences between the agents in ICP at hypocapnia. The present study showed that desflurane increased ICP more and sevoflurane less than isoflurane during normoventilation, but the differences disappeared with hyperventilation.

    Purpose: To assess toxicity in patients with either a collagen vascular disease (CVD) or multiple sclerosis (MS) treated with intracranial radiosurgery. Methods and Materials: Between January 2004 and April 2009, 6 patients with MS and 14 patients with a CVD were treated with Gamma Knife radiosurgery (GKRS) for intracranial tumors. Treated lesions included 15 total brain metastases in 7 patients, 11 benign brain tumors, 1 low grade glioma, and 1 cavernous malformation. Toxicities were graded by the Radiation Therapy Oncology Group Acute/Late Radiation Morbidity Scoring Criteria. 'Rare toxicities' were characterized as those reported in the scientific literature at an incidence of <5%. Results: Median follow-up time was 16 months. Median dose to the tumor margin was 13.0 Gy (range, 12-21 Gy). Median size of tumor was 5.0 cm{sup 3} (range, 0.14-7.8 cm{sup 3}). Of the 14 patients with CVD, none experienced a Grade 3 or 4 toxicity or a toxicity characterized as rare. Of the 6 patients with MS, 3 experienced rare toxicities, and two of these were Grade 3 toxicities. Rare complications included a patient experiencing both communicating hydrocephalus and facial nerve palsy, as well as 2 additional patients with motor cranial nerve palsy. High-grade toxicities included the patient with an acoustic neuroma requiring ventriculoperitoneal shunt placement for obstructive hydrocephalus, and 1 patient with a facial nerve schwannoma who experienced permanent facial nerve palsy. Interval between radiosurgery and high-grade toxicities ranged from 1 week to 4 months. Conclusions: Our series suggests that patients with MS who receive GKRS may be at increased risk of rare and high-grade treatment-related toxicity. Given the time course of toxicity, treatment-related edema or demyelination represent potential mechanisms.

    Breast cancer brain metastases (BCBMs) are common in patients with metastatic breast cancer and indicate a poor prognosis. These tumors are especially resistant to currently available treatments due to multiple factors. However, the combination of chimeric antigen receptor (CAR)-modified immune cells and oncolytic herpes simplex virus (oHSV) has not yet been explored in this context. In this study, NK-92 cells and primary NK cells were engineered to express the second generation of EGFR-CAR. The efficacies of anti-BCBMs of EGFR-CAR NK cells, oHSV-1, and their combination were tested in vitro and in a breast cancer intracranial mouse model. In vitro, compared with mock-transduced NK-92 cells or primary NK cells, EGFR-CAR-engineered NK-92 cells and primary NK cells displayed enhanced cytotoxicity and IFN-γ production when co-cultured with breast cancer cell lines MDA-MB-231, MDA-MB-468, and MCF-7. oHSV-1 alone was also capable of lysing and destroying these cells. However, a higher cytolytic effect of EGFR-CAR NK-92 cells was observed when combined with oHSV-1 compared to the monotherapies. In the mice intracranially pre-inoculated with EGFR-expressing MDA-MB-231 cells, intratumoral administration of either EGFR-CAR-transduced NK-92 cells or oHSV-1 mitigated tumor growth. Notably, the combination of EGFR-CAR NK-92 cells with oHSV-1 resulted in more efficient killing of MDA-MB-231 tumor cells and significantly longer survival of tumor-bearing mice when compared to monotherapies. These results demonstrate that regional administration of EGFR-CAR NK-92 cells combined with oHSV-1 therapy is a potentially promising strategy to treat BCBMs.

  16. AKT1 Activation Promotes Development of Melanoma Metastases

    Full Text Available Metastases are the major cause of melanoma-related mortality. Previous studies implicating aberrant AKT signaling in human melanoma metastases led us to evaluate the effect of activated AKT1 expression in non-metastatic BRAFV600E/Cdkn2aNull mouse melanomas in vivo. Expression of activated AKT1 resulted in highly metastatic melanomas with lung and brain metastases in 67% and 17% of our mice, respectively. Silencing of PTEN in BRAFV600E/Cdkn2aNull melanomas cooperated with activated AKT1, resulting in decreased tumor latency and the development of lung and brain metastases in nearly 80% of tumor-bearing mice. These data demonstrate that AKT1 activation is sufficient to elicit lung and brain metastases in this context and reveal that activation of AKT1 is distinct from PTEN silencing in metastatic melanoma progression. These findings advance our knowledge of the mechanisms driving melanoma metastasis and may provide valuable insights for clinical management of this disease.

    To assess the clinical value of treatment with 131I for brain metastases from differentiated thyroid cancer (DTC), we have observed 8 cases of brain metastases from DTC who received follow-up after 131I therapy (2male, 6 female, aged 12~65 years). The results of 131I therapy were evaluated with clinical presentation, imaging scan and survival analysis. The main results are as follows. (1) All cases had been survival for 2~35 years in follow-up. (2)A space-occupying lesion in right cerebellum was reduced after taking 20.65 GBq and disappeared after 23.61 GBq,demonstrated by computed tomography. (3) The sequences and doses of 131I therapy were clearly decreased for the cases with total thyroidectomy in comparison with those with semithyroidectomy (p<0.01). (4) The brain metastases with lung and/or bone metastasis from DTC were 75% (6/8) and it was difficult to cure these metastases at the same time. It is concluded that the postoperative treatment of 131I for brain metastases from DTC after undergoing thyroidectomy may improve clinical symptoms and life quality, reduce lesions, and prolong survival.

    Full Text Available Development of effective treatment for hepatic metastases can be initiated by a better understanding of tumour vasculature and blood supply. This study was designed to characterise the microvascular architecture of hepatic metastases and observe the source of contributory blood supply from the host. Metastases were induced in mice by an intrasplenic injection of colon carcinoma cells (106 cells/ml. Vascularization of tumours was studied over a three week period by scanning electron microscopy of microvascular corrosion casts. Metastatic liver involvement was observed initially within a week post induction, as areas approximately 100 μm in diameter not perfused by the casting resin. On histology these spaces corresponded to tumour cell aggregates. The following weeks highlighted the angiogenesis phase of these tumours as they received a vascular supply from adjacent hepatic sinusoids. Direct sinusoidal supply of metastases was maintained throughout tumour growth. At the tumour periphery most sinusoids were compressed to form a sheath demarcating the tumour from the hepatic vasculature. No direct supply from the hepatic artery or the portal vein was observed. Dilated vessels termed vascular lakes dominated the complex microvascular architecture of the tumours, most tapering as they traversed towards the periphery. Four vascular branching patterns could be identified as true loops, bifurcations and trifurcations, spirals and capillary networks. The most significant observation in this study was the direct sinusoidal supply of metastases, together with the vascular lakes and the peripheral sinusoidal sheaths of the tumour microculature.

    Bone metastases are rare in primary hepatocellular carcinoma (HCC). Spinal cord compression (SCC) due to bone metastases occur commonly in patients with lung and breast carcinomas, and metastatic HCC is an unusual cause of SCC. Spinal cord compression is an oncologic emergency and treatment delays can lead to irreversible consequences. Thus, the awareness that SCC could be a potential complication of bone metastases due to HCC is of significance in initiation of early treatment that can improve the quality of life and survival of the patients, if diagnosed earlier. This paper describes four cases of primary HCC with varied manifestations of SCC due to bone metastases. The first patient presented primarily with the symptoms of bone pains corresponding to the bone metastases sites rather than symptoms of associated hepatic pathology and eventually developed SCC. The second patient, diagnosed as having HCC, developed extradural SCC leading to paraplegia during the course of illness, for which he underwent emergency laminectomy with posterior fixation. The third patient developed SCC soon after the primary diagnosis and had to undergo emergency laminectomy. Post laminectomy he had good neurological recovery. The Fourth patient presented primarily with radicular pains rather than frank paraplegia as the first manifestation of SCC.

    Surgical resection provides long term survival in approximately 30% of patients with colorectal carcinoma (CRC) liver metastases. However, only a limited number of patients with CRC-metastases are amendable for surgery. We have tested the effect of stereotactic body radiotherapy (SBRT) in the treatment of inoperable patients with CRC-metastases. Sixty-four patients with a total number of 141 CRC-metastases in the liver (n=44), lung (n=12), lymph nodes (n=3), suprarenal gland (n=1) or two organs (n=4) were treated with SBRT with a central dose of 15 Gyx3 within 5-8 days. Median follow-up was 4.3 years. After 2 years, actuarial local control was 86% and 63% in tumor and patient based analysis, respectively. Nineteen percent were without local or distant progression after 2 years and overall survival was 67, 38, 22, 13, and 13% after 1, 2, 3, 4 and 5 years, respectively. One patient died due to hepatic failure, one patient was operated for a colonic perforation and two patients were conservatively treated for duodenal ulcerations. Beside these, only moderate toxicities such as nausea, diarrhoea and skin reactions were observed. SBRT in patients with inoperable CRC-metastases resulted in high probability of local control and promising survival rate. One toxic death and few severe reactions were observed. For the majority of patients, the treatment related toxicity was moderate.
