    Cavernous sinus thrombosis represents a rare but devastating disease process that may be associated with significant long-term patient morbidity or mortality. The prompt recognition and management of this problem is critical. However, most of the literature involves case-specific discussions. The purpose of this article was to review the literature and present current recommendations for the treatment of cavernous sinus thrombosis.

    The cavernous sinus is a venous plexus crossed by vital neurovascular structures. Metastases to the region are uncommon and often associated with a headache, facial pain, or progressive neurological deficit in III, IV, and VI cranial nerves. The treatment options are surgery, including endoscopic approach, radiotherapy, radiosurgery, and chemotherapy. We report the case of a 26-year-old female with cavernous sinus syndrome due to breast cancer metastasis, who was subjected to chemotherapy with complete neurological recovery. A literature review was performed using the databases Bireme, Pubmed, Cochrane, Lilacs and Medline with the keywords: cavernous sinus/metastasis/surgery/radiosurgery for multiple management options review. Cavernous sinus metastases are rare, and the cavernous sinus syndrome is rarely the first sign of cancer, especially in young patients. Because the syndrome has multiple causes, the history of rapid progression and atypical image findings can arise suggesting metastatic diseases. As in our case, the image was suggestive of meningioma, however, the clinical presentation and further investigations led us to suspect as a metastatic disease. The therapeutic decision considers clinical and functional status, the extent of primary and metastatic disease, radiological study, tumor histopathology, and biological behavior. Often associated with significant symptoms and disseminated systemic disease, nowadays radiosurgery is the first and less invasive strategy, offering low risk of new deficits, clinical improvement, and good local control. The prognosis depends on early treatment and disease staging because mortality is associated with progression of cancer.

    Objective: To describe clinical characteristics, imaging findings, morbidity, and mortality in a single-center cohort of 12 pediatric cavernous sinus thrombosis cases and to review all cases available in recent English literature. Methods: Clinical data and radiographic studies on 12 cases from our institution were analyzed retrospectively. A literature search and review was conducted, with additional cases pooled with the new cohort for an aggregate analysis. Results: Twelve cases of cavernous sinus thrombosis in children from the Children's Hospital of Philadelphia between January 1, 2000, and December 31, 2013, were reviewed. All patients survived to discharge; 3 of 12 (25%) experienced neurologic morbidity. Contrast-enhanced MRI and contrast-enhanced head CT were 100% sensitive for detecting cavernous sinus thrombosis, while noncontrast time-of-flight magnetic resonance venography (TOF MRV) and noncontrast head CT were 0% sensitive. Literature review produced an additional 40 cases, and the aggregate mortality rate was 4 of 52 (8%) and morbidity rate was 10 of 40 (25%). Outcomes did not vary by treatment or with unilateral vs bilateral cavernous sinus involvement. There was a trend toward worse outcomes with fungal infections. Conclusion: Our case series demonstrates low morbidity and mortality with early, aggressive surgical, antimicrobial, and anticoagulation therapies. Although anticoagulation and surgery were not associated with significantly different outcomes, more study is needed. PMID:26231260

    The cavernous sinus can be affected by a wide range of conditions including tumours, infection, inflammation, and trauma. Disease in the cavernous sinus can produce characteristic signs and symptoms, which relate to the numerous crucial structures traversing and surrounding the cavernous sinus. Imaging, with the use of different techniques, plays a crucial role in diagnosis and management. The anatomy and imaging of the different disease entities in the cavernous sinus will be reviewed.

    Primary moyamoya disease associated with skull base tumors has been reported only rarely in the literature. Surgical treatment can be complicated due to the compensatory collateral circulation through meningeal and leptomeningeal anastomosis. A standard frontotemporal craniotomy may interrupt critical transdural anastomoses. We report a case of primary moyamoya disease coexisting with tuberculum sellae meningioma and left cavernous sinus hemangioma. Simultaneous management of tuberculum sellae meningioma and moyamoya disease was performed using a left modified pterional incision. Two separate bone windows were opened to protect the transdural anastomosis via the middle meningeal artery. The tuberculum sellae meningioma was successfully removed through a small frontal craniotomy, and encephaloduromyosynangiosis was used to treat moyamoya disease through a temporoparietal craniotomy. Finally, CyberKnife radiotherapy was used to treat the left cavernous sinus hemangioma at 6 weeks after the initial operation. The patient recovered well without complications. This is the first report of moyamoya disease associated with tuberculum sellae meningioma and cavernous sinus hemangioma. With careful bone flap design, moyamoya disease and skull base tumors can be treated simultaneously. Care should be taken to avoid interruption of critical dural-pial collaterals and injury to fragile moyamoya vessels. Copyright © 2017 Elsevier Inc. All rights reserved.

    To evaluate the MR findings of septic thrombosis of the cavernous sinus. Eleven MR images of six patients with septic cavernous sinus thrombosis obtained over a five-year period and proven clinically or radiologically were retrospectively reviewed. The contour and enhancement pattern of the cavernous sinus, changes in the internal carotid artery, orbit, pituitary gland and sphenoid sinus, and intracranial abnormalities were analyzed and compared with the findings of follow-up studies. In all six patients, contrast study revealed asymmetrical enlargement of the ipsilateral cavernous sinus and multiple irregular filling defects within it. Narrowing of the cavernous portion of the ipsilateral internal carotid artery was noted in five patients, upward displacement of the ipsilateral internal carotid artery in four, ipsilateral proptosis with engorgement of the superior ophthalmic vein in two, pituitary enlargement in five, and inflammatory change in the sphenoid sinus in six. Associated intracranial abnormalities included edema and enhancement in the meninx, temporal lobe, or pons adjacent to the cavernous sinus in four patients, hydrocephalus in one, and cerebral infarction in one. Follow-up MR imaging indicated that the extent of asymmetrical enlargement of the cavernous sinus, filling defects within it, as seen on contrast study, and enlarged pituitary glands had all decreased, without significant interval change. MR imaging is useful in the diagnosis of septic cavernous sinus thrombosis. Asymmetrical enlargement of the cavernous sinus, multiple irregular filling defect within it, as seen on contrast study, and changes in the internal carotid artery are characteristic findings.

    We report the case of an infant with a mature teratoma of the lateral wall of the cavernous sinus. A complete excision of the tumor was achieved. There was no evidence of recurrence at 1-year follow-up examination. Intracranial teratomas and the anatomy of the lateral wall of the cavernous sinus are briefly reviewed. To our knowledge, this is the first case of a teratoma confined to the cavernous sinus.

    Cavernous sinus cavernous hemangiomas in pregnancy are extremely rare lesions. The precise management of these lesions remains unknown. The authors present a case of a cavernous hemangioma in pregnancy, centered within the cavernous sinus that underwent postpartum involution without surgical intervention. A 34-year-old pregnant patient (gravida 1, para 0) presented to an otolaryngologist with persistent headache and left-sided facial pain and numbness in the V1 distribution. While being treated for sinusitis, her symptoms progressed to include a left-sided oculomotor palsy and abducens palsy. Magnetic resonance imaging without contrast revealed an expansile mass within the left cavernous sinus consistent with a cavernous hemangioma. The patient was evaluated by a neurosurgeon who recommended close follow-up and postpartum imaging without surgical intervention. Although the lesion enlarged during pregnancy, the patient was able to undergo an uncomplicated cesarean section at 37 weeks. All facial and ocular symptoms resolved by 9 months postpartum, and MRI showed a decrease in lesion size and reduced mass effect. The authors conclude that nonsurgical management may be a viable approach in patients who have an onset or exacerbation of symptoms associated with cavernous sinus cavernous hemangiomas during pregnancy because postpartum involution may negate the need for surgical intervention.

    The type of pituitary adenoma with a manifestation that includes cavernous sinus syndrome is rare. Based on the clinical data of 70 patients, this study investigated the pathogenesis, imaging characteristics, and prognostic factors of pituitary adenoma with cavernous sinus syndrome. We conducted a retrospective analysis of the characteristics of patients with pituitary adenoma with cavernous sinus syndrome who received surgical treatment. The patients were classified into different prognosis groups according to the time required for them to recover from the cavernous sinus syndrome. Univariate analyses were conducted for the correlations between the prognosis and factors. Of the 3598 cases of pituitary adenomas, 70 (1.95%) presented cavernous sinus syndrome. Of the patients, 55.7% recovered within 2 weeks of surgery, 24.3% recovered from 2 weeks to 1 year after surgery, and 20% had not returned to normal after more than 1 year after surgery. Univariate analyses showed that shorter disease duration (P syndrome differs depending on the mechanism of the syndrome. There was no significant difference in the prognosis between patients with total pituitary adenoma resection and subtotal resection. Timely surgery within 100 days of symptom occurrence, Knosp grade 0-2, and associated pituitary apoplexy are predictive factors of good prognosis. Copyright © 2017 Elsevier Inc. All rights reserved.

    Background: We report the recovery of ophthalmoplegia in 11 patients with cavernous sinus dural arteriovenous fistula (CSDAVF) after sinus packing at follow-up. Methods: Of 18 patients with CSDAVF treated with transvenous cavernous sinus packing between August 2002 and December 2007 at Beijing Tiantan Hospital, there were 9 patients with initial CNIII or CNVI dysfunction and 2 patients with CNVI dysfunction immediately after cavernous sinus packing selected and reevaluated. Results: Of 11 patients with CNIII or CNVI palsy, recovery was complete in 10. In 1 patient, complete CNVI palsy was unchanged because the CSDAVF was not cured. There were 6 men and 5 women with a mean age of 52.9 years. In 5 patients, CNVI palsy was associated with chemosis, proptosis and pulsatile tinnitus. Timing of treatment after onset of symptoms was from 4 to 35 days in 9 patients. All CSDAVFs were Barrow type D. Mean follow-up after treatment was 17.7 months (range, 2-54 months). Conclusion: CSDAVF-induced CNIII or CNVI palsies can be cured after cavernous sinus packing transvenously in most patients.

    Cavernous sinus angioleiomyoma (ALM) is extremely rare. Only three cases have been reported to be cavernous sinus ALM, and very few reports described characteristic findings for intracranial ALMs in detail. We report a new case of cavernous sinus ALM, with detailed information on the clinical presentation, radiology, pathology, and surgical approach. A 52-year-old woman had a 6-month history of right eye discomfort. Magnetic resonance imaging showed a right cavernous sinus tumor with heterogenous blush enhancement. Enhanced computed tomography scans and angiography showed small nodular enhancement in the tumor. Complete tumor resection was achieved via an extradural temporopolar approach. ALM was identified based on histologic examination. Intracranial ALMs are different from the ALMs that occur in the extremities based on our review of the literature. Intracranial ALMs appear more frequently in men than women. The cavernous type was the most common pathologically, and they occur often in the epiperidural location. Because cavernous sinus ALM occurs in the interdural space, an epidural approach should be selected. Therefore, it is important to include cavernous sinus ALM into a differential diagnosis of a cavernous sinus tumor. The blush enhancement and nodular enhancement within this lesion may be useful to distinguish cavernous sinus ALM from other differential diagnoses.

    Full Text Available Necrotizing fasciitis is a rapidly progressive life threatening bacterial infection of the skin, the subcutaneous tissue, and the fascia. We present a case of necrotizing fasciitis involving the nose complicated by cavernous sinus thrombosis. Few cases of septic cavernous sinus thrombosis have been reported to be caused by cellulitis of the face but necrotizing fasciitis of the nose is rare. It is very important to recognize the early signs of cavernous thrombosis. Treatment for septic cavernous sinus thrombosis is controversial but early use of empirical antibiotics is imperative.

    Carotid cavernous sinus fistulas are abnormal communications between the carotid system and the cavernous sinus. Several classification schemes have described carotid cavernous sinus fistulas according to etiology, hemodynamic features, or the angiographic arterial architecture. Increased pressure within the cavernous sinus appears to be the main factor in pathophysiology. The clinical features are related to size, exact location, and duration of the fistula, adequacy and route of venous drainage and the presence of arterial/venous collaterals. Noninvasive imaging (computed tomography, magnetic resonance, computed tomography angiography, magnetic resonance angiography, Doppler) is often used in the initial work-up of a possible carotid cavernous sinus fistulas. Cerebral angiography is the gold standard for the definitive diagnosis, classification, and planning of treatment for these lesions. The endovascular approach has evolved as the mainstay therapy for definitive treatment in situations including clinical emergencies. Conservative treatment, surgery and radiosurgery constitute other management options for these lesions. PMID:23671750

    Objective To analyze whether cavernous sinus sampling (CSS) and dynamic magnetic resonance imaging (dMRI) are consistent with intraoperative findings in Cushing disease (CD) patients. Design Retrospective outcomes study. Setting Oregon Health & Science University; 2006 and 2013. Participants A total of 37 CD patients with preoperative dMRI and CSS to confirm central adrenocorticotropic hormone (ACTH) hypersecretion. Patients were 78% female; mean age was 41 years (at diagnosis), and all had a minimum of 6 months of follow-up. Main Outcome Measures Correlations among patient characteristics, dMRI measurements, CSS results, and intraoperative findings. Results All CSS indicated presence of CD. Eight of 37 patients had no identifiable tumor on dMRI. Three of 37 patients had no tumor at surgery. dMRI tumor size was inversely correlated with age (rs = − 0.4; p = 0.01) and directly correlated to intraoperative lateralization (rs = 0.3; p < 0.05). Preoperative dMRI was directly correlated to intraoperative lateralization (rs = 0.5; p < 0.002). CSS lateralization showed no correlation with intraoperative findings (rs = 0.145; p = 0.40) or lateralization observed on preoperative dMRI (rs = 0.17; p = 0.29). Postoperative remission rate was 68%. Conclusion dMRI localization was most consistent with intraoperative findings; CSS results were less reliable. Results suggest that small ACTH-secreting tumors continue to pose a challenge to reliable preoperative localization. PMID:26225305

    Describe the outcomes of patients diagnosed with indirect carotid-cavernous fistula treated by endovascular methods. A retrospective case series. Twelve patients with dural cavernous sinus fistula with important ophthalmologic involvement admitted and treated at the National Institute of Neurology and Neurosurgery between February 1990 and January 2005. Patients were managed by endovascular embolization for all fistulas. Angiographic controls to 24 hours and at 6 and 12 months were performed. 67 % were female and 33 % male. The mean age was 44 years. 67 % were spontaneous and 33% of traumatic origin. All patients had eye involvement with proptosis (92%) and involvement of the oculomotor nerve (67%). Headache and pulsatile tinnitus were not frequent ophthalmologic data. All were diagnosed by cerebral angiography, 33 % were type C, type D 67 %, and none of the type B classification Barrow. In 17 % of cases the distal arterial robbery showed severe. Predominance of anterior and superior venous drainage in 83 % and 42 % of cases occurred respectively. The surgical approach was arterial in 84% of cases, while in 17 % venous through the superior ophthalmic vein. Cyanoacrylate embolization material was used in 58 % of the cases, as it was associated with the use of removable ball with polyvinyl alcohol particles in 16 % in of venous approach cases. 17% detachable coils were utilized. There were no complications. After angiographic controls at 24 hours 100% occlusion was seen in patients treated with cyanoacrylate (58%) (p = 0.03). The remaining 42% were prescribed maneuver of manual compression. At 12-months angiography all patients had 100% occlusion of the carotid-cavernous fistula. CONCLSUIONS: This is the world's second largest series with indirect carotid-cavernous fistulas treated after trauma. 100 % of cases were cured with the use of a transarterial-controlled approach and N-butyl-cyanoacrylate after long-term observation.

    Cavernous sinus cavernous hemangioma (CSCH) is a rare extra-axial vascular lesion and is difficult to be removed due to their location, propensity for profuse bleeding during surgery, and relationship to complex neurovascular structures. The purpose of this study is to report our experience of the removal of CSCHs through a completely extradural transcavernous approach. Twelve patients with CSCH, who were operated through a purely extradural approach, were retrospectively studied. Clinical symptoms and signs, radiographic characteristics, operative techniques and outcomes of these patients were analyzed. Headache and visual impairment were the most common clinical symptoms, followed by facial hypesthesia and ptosis. Radiographically, CSCHs have a characteristic pattern. On computed tomography (CT) scans, CSCHs are isodense or minimally hyperdense, with an intense homogenous contrast administration. Magnetic resonance image (MRI) scans revealed well-demarcated and hypo- to isointense lesions on T1-weighted images and characteristically, markedly hyperintense lesions on T2-weighted images. The T2-weighted images showed a marked homogeneous and an intense enhancement after contrast administration. All CSCHs were treated by a completely extradural transcavernous approach. Gross total excision was achieved in all 12 patients. Post-operative complication included transient cranial nerve dysfunction for 2-3 months in eight patients, and three patients developed a permanent VI nerve palsy. The follow-up period ranged from 4 to 117 months (mean 62 months), and no patient had experienced tumor recurrence. CSCHs are rare and challenging skull base tumors. The microsurgical resection, using an extradural transcavernous approach which allows complete tumor resection with an acceptable intraoperative and postoperative complications, should be considered as a favorable choice among all treatments.

    Bilateral carotid cavernous fistulas are rare entities that can cause debilitating symptoms and can lead to more severe consequences if left untreated. Therefore, the recognition and adequate treatment of these pathologies is very important. We present 2 cases of bilateral carotid cavernous fistulas that arose as a result of cavernous sinus thrombosis. We review the literature and discuss the pathophysiology, symptomatology, management, and treatment of bilateral carotid cavernous fistulas. Within our own cases, treatment of the patients was varied. The patient in case 1 was successfully treated with endovascular therapy after a failed trial of anticoagulation. The patient in case 2 demonstrated resolution of bilateral carotid cavernous fistulas after anticoagulation therapy. Case 2 highlights the fact that certain cases of bilateral carotid cavernous fistulas due to cavernous sinus thrombosis may benefit from extensive anticoagulation therapy. If anticoagulation therapy is unsuccessful, endovascular therapy may prove beneficial in resolving the fistulous shunt. Copyright © 2017 by the Congress of Neurological Surgeons.

    2014-06-01

    Cavernous sinus syndrome is characterised by internal and external ophthalmoplegia and sensory deficits over the head due to combined deficits of the three cranial nerves (CNs) responsible for the eye movements and pupil function (CN III, IV, VI) and at least one branch of the trigeminal nerve (CN V). It has rarely been described in cats and may occur secondarily to inflammatory, infectious or neoplastic lesions within the region of the cavernous sinus on the ventral aspect of the calvarium. This report describes the clinical and magnetic resonance imaging findings in a 14-year-old domestic shorthair cat with neurological deficits compatible with cavernous sinus syndrome caused by presumptive extranodal lymphoma. Treatment with chemotherapy resulted in clinical and imaging remission. Identification of the neurological deficits in cavernous sinus syndrome allows accurate neuroanatomical localisation in order to target diagnostic imaging studies. © ISFM and AAFP 2013.

    2013-01-01

    Objective To design and assess the quality of a novel lateral retrocanthal endoscopic approach to the lateral cavernous sinus. Design Computer modeling software was used to optimize the geometry of the surgical pathway, which was confirmed on cadaver specimens. We calculated trajectories and surgically accessible areas to the middle fossa while applying a constraint on the amount of soft tissue retraction. Setting Virtual computer model to simulate the surgical approach and cadaver laboratory. Participants The authors. Main Outcome Measures Adequate surgical access to the lateral cavernous sinus and adjacent regions as determined by operations on the cadaver specimens. Additionally, geometric limitations were imposed as determined by the model so that retraction on soft tissue structures was maintained at a clinically safe distance. Results Our calculations revealed adequate access to the lateral cavernous sinus, Meckel cave, orbital apex, and middle fossa floor. Cadaveric testing revealed sufficient access to these areas using cavernous sinus. PMID:24498584

    Cavernous sinus thrombophlebitis is a serious disease. We report herein a case seen in a 9-year-old boy hospitalized for an acute pneumopathy. Clinical signs were made of a diffuse edema of the upper two-thirds of the face, eyelid edema, chemosis, exophthalmia, meningeal syndrome, and infections syndromes associated with alteration of consciousness. A CT scan revealed a heterogenous enhancement and enlargement of the left cavernous sinus and homogenous opacity of the sphenoidal sinuses. Therapeutic management was complicated due to allergy to β-lactams and the multidrug resistance of Staphylococcus aureus. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    A wide variety of lesions may develop in the cavernous sinus region, including tumors or pseudotumors of inflammatory origin. Sometimes imaging is insufficient to ascertain a pathologic diagnosis. Percutaneous biopsy performed through the foramen ovale route may aid therapeutic decision making, avoiding unnecessary open surgery when lesions are confirmed to be nonsurgical or unresectable. We conducted a systematic review to determine the efficacy of percutaneous biopsy of cavernous sinus lesions. A systematic search in PubMed, LILACS, Web of Science, and Scopus yielded 4495 potentially eligible abstracts. Fourteen studies describing 75 biopsy procedures for lesions in the cavernous sinus region were reviewed. The primary outcome measure was diagnostic success. Data were analyzed according to standard systemic review techniques. A diagnosis was obtained in 65 of the 75 cases described in the literature. Among all series, only 3 patients had permanent deficits. No individual studies reported mortality. The histopathologic evaluation revealed neoplastic diseases in 58 lesions. Meningiomas were found in 26 biopsy samples. Nonneoplastic diseases, originating from infectious, inflammatory, or deposition diseases, accounted for 6 biopsy samples. Percutaneous biopsy of cavernous sinus lesions is effective for diagnosis. Biopsy can be performed in patients with cavernous sinus masses, especially when neuroimaging fails to provide sufficient histopathologic data. Copyright © 2017 Elsevier Inc. All rights reserved.

    Objective Three-dimensional anatomical appreciation of the matrix of the cavernous sinus is one of the crucial necessities for a better understanding of tissue patterning and various disorders in the sinus. The purpose of this study was to reveal configuration of fibrous and adipose components in the cavernous sinus and their relationship with the cranial nerves and vessels in the sinus and meningeal sinus wall. Materials and Methods Nineteen cadavers (8 females and 11 males; age range, 54–89 years; mean age, 75 years) were prepared as transverse (6 sets), coronal (3 sets) and sagittal (10 sets) plastinated sections that were examined at both macroscopic and microscopic levels. Results Two types of the web-like fibrous networks were identified and localized in the cavernous sinus. A dural trabecular network constituted a skeleton-frame in the sinus and contributed to the sleeves of intracavernous cranial nerves III, IV, V1, V2 and VI. A fine trabecular network, or adipose tissue, was the matrix of the sinus and was mainly distributed along the medial side of the intracavernous cranial nerves, forming a dumbbell-shaped adipose zone in the sinus. Conclusions This study revealed the nature, fine architecture and localization of the fine and dural trabecular networks in the cavernous sinus and their relationship with intracavernous cranial nerves and vessels. The results may be valuable for better understanding of tissue patterning in the cranial base and better evaluation of intracavernous disorders, e.g. the growth direction and extent of intracavernous tumors.

    Venous sampling methods are valuable tools for the diagnosis of pituitary adenomas. However, these interventions also have complications, which may complicate the treatment process. A 49-year-old female pituitary adenoma patient with preliminary diagnosis of Cushing disease underwent cavernous sinus sampling (CSS) to delineate the adenoma. The microguidewire broke during the procedure, and the distal part of the microguidewire had to be left within the right cavernous sinus. Eventually, the broken part of the guidewire was removed after the removal of the tumor through an endoscopic endonasal approach. Current surgical experience on endoscopic skull base surgery allows management of diagnostic complications related to the cavernous sinus, such as safe access to materials which were inadvertently left during CSS, without the necessity for further interventions.

    We report the CT and MRI findings of congenital bilateral plexiform neurofibromas of the cavernous sinuses in a 2-month-old girl. Contrast-enhanced CT showed enhancement of masses in both cavernous sinuses and enlargement of both superior orbital fissures. On MRI the masses were isointense with muscle on T1-weighted images, hypointense on T2-weighted images and showed strong homogeneous enhancement on contrast-enhanced T1-weighted images. A dural tail sign was observed. The diagnosis was proven by biopsy. (orig.)

    The cavernous sinus is a small complex structure located at the central base of the skull. Recent extensive use of endoscopy has provided less invasive approaches to the cavernous sinus via endonasal routes, although transcranial routes play an important role in the approach to the cavernous sinus. The aims of this study were to evaluate the feasibility of the purely endoscopic transcranial approach to the cavernous sinus through the supraorbital keyhole and to better understand the distorted anatomy of the cavernous sinus via endoscopy. Eight fresh cadavers were studied using 4-mm 0° and 30° endoscopes to develop a surgical approach and to identify surgical landmarks. The endoscopic supraorbital extradural approach was divided into 4 stages: entry into the extradural anterior cranial fossa, exposure of the middle cranial fossa and the periorbita, exposure of the superior cavernous sinus, and exposure of the lateral cavernous sinus. This approach provided superb views of the cavernous sinus structures, especially through the clinoidal (Dolenc) triangle. The lateral wall of the cavernous sinus, including the infratrochlear (Parkinson) triangle and anteromedial (Mullan) triangle, was also clearly demonstrated. An endoscopic supraorbital extradural approach offers excellent exposure of the superior and lateral walls of the cavernous sinus with minimal invasiveness via the transcranial route. This approach could be an alternative to the conventional transcranial approach.

    Haber, Daniel Martiniano

    2008-12-01

    Full Text Available Introduction: Mucormycosis is a rare opportunistic infection caused by Mucorales fungi, and the Rhizopus is the most common one (70% of the cases. It is an acute invasive fungal disease whose form is disseminated, cutaneous, pulmonary, gastrointestinal and rhino-orbitocerebral. The latter is the most common form and its symptoms comprise of unilateral sinusitis, fever and headache. Once established in the orbit the symptoms can be chemosis, diplopia and reduced vision. The infection can spread to the brain via the orbital apex, orbital arteries or via the cribriform plate. Mucormycosis is a medical emergency and the treatment consists of a surgery to an aggressive debridement and in the use of antifungal therapy. Despite the appropriate management, the mortality rate can reach 40% of the cases. One possible intracranial complication of Mucormycosis is the Cavernous Sinus Thrombosis which is a rare and fatal infective disease. The initial symptoms of Cavernous Sinus Thrombosis are headache, retro-orbital pain, periorbital edema, proptosis, diplopia and reduced vision. Case Report: We describe the case of 43-year-old woman with medical history of diabetes mellitus and use of immunosuppressant drugs after kidney transplantation. The patient developed Acute Bacterial Sinusitis and Rhino-orbitocerebral Mucormycosis associated with Cavernous Sinus Thrombosis.

    Septic thrombosis of the cavernous sinus (STCS) is an uncommon and potentially lethal disease. Sphenoid and ethmoid sinusitis followed by facial cutaneous infections represents the most common aetiologies, with Staphylococcus aureus as the main responsible organism followed by the Streptococcus pneumoniae. Although all infectious foci of the head and neck area can potentially spread to the cavernous sinus, STCS from oral infection is an exceptionally rare occurrence. We report the unusual case of a patient who presented with an acute STCS secondary to a generalized Streptococcus milleri periodontitis. This case highlights the importance of systematically performing a detailed examination of the oral cavity in patients presenting with intracranial infections caused by uncommon pathogens such as the Streptococcus milleri group.

    Full Text Available We present a 25 year-old man with episodic cluster headache that was refractory to all standard pharmacological prophylactic and abortive treatments. Because of the lack of response, an MRI brain was performed which showed a large pituitary tumour with ipsilateral cavernous sinus invasion. The serum prolactin was significantly elevated at 54,700 miU/L (50–400 confirming a macro-prolactinoma. Within a few days of cabergoline therapy the headache resolved. He continues to be headache free several years after starting the dopamine agonist. This case highlights the importance of imaging the pituitary fossa in patients with refractory cluster headache, It also raises the potential anatomical importance of the cavernous sinus in pituitary-associated headache.

    We report three cases of dural arteriovenous fistula (DAVF) of the cavernous sinus treated by Onyx injection through the superior pharyngeal branch of the ascending pharyngeal artery. The treatment of choice of DAVFs of the cavernous sinus is endovascular, and it is preferentially done via transvenous occlusion of the cavernous sinus. The cavernous sinus can be reached through either the inferior petrosal sinus or the superior ophthalmic vein. When these venous routes are occluded, the first ...

    Sphenoid wing meningiomas (SWMs) typically are histologically benign, insidious lesions, but the propensity of these tumors for local invasion makes disease control very challenging. In this review, we assess whether the degree of resection and extent of cavernous sinus invasion affects morbidity, mortality, and recurrence in patients with SWM. A comprehensive search of the English-language literature was performed. Patients were stratified according to extent of resection and extent of cavernous sinus invasion, and tumor recurrence rate, morbidity, and mortality were analyzed. A total of 23 studies and 131 patients were included. Overall recurrence and surgical mortality rate were 11% and 2%, respectively (average follow-up = 65 months). Cranial nerve III palsy was significantly associated with incompletely versus completely resected SWMs (7 to 0%) as well as meningiomas with cavernous sinus invasion versus no sinus invasion (14 vs. 0%). No significant difference in tumor recurrence rate was noted between these groups. In conclusion, complete excision of SWMs is always recommended whenever possible, but surgeons should acknowledge that there is nonetheless a chance of recurrence and should weigh this against the risk of causing cranial nerve injuries.

    2018-01-01

    Rupture of a persistent trigeminal artery associated with development of a cavernous sinus fistula in a traumatic setting is rare. These arteries are typically treated with coil embolization of the cavernous sinus. We present the case of a 42-year-old woman who developed a direct cavernous carotid fistula after a motor vehicle accident. Angiographic imaging revealed a rupture point of a persistent trigeminal artery as it connected with the cavernous segment of the internal carotid artery, causing a cavernous sinus fistula. Coiling of the cavernous sinus was abandoned after placement of 1 coil because of coil herniation into the internal carotid artery. A Pipeline embolization device was placed to oppose the coil against the intima and keep the lumen open. The combination of coil embolization and flow diversion acutely decreased the fistulous flow. Surprisingly, an angiographic follow-up at 6 months showed complete fistula occlusion despite placement of only 1 coil into the cavernous sinus. We report a rare case where undercoiling of the cavernous sinus occluded a cavernous sinus fistula because of the adjunct use of a Pipeline embolization device in the presence of a traumatic rupture of a persistent trigeminal artery.

    We report the case of a patient with cavernous sinus syndrome associated with biopsy-confirmed metastasis from colorectal cancer. A patient known for laryngeal carcinoma and metastatic colorectal carcinoma presented with symptoms of left trigeminal neuralgia and progressive, near-complete ophthalmoplegia. Magnetic resonance imaging (MRI) revealed a mass in the left cavernous sinus, extending into Meckel's cave with perineural spread along the mandibular branch of the left trigeminal nerve. A transsphenoidal biopsy was performed and demonstrated metastatic colon adenocarcinoma. We review the existing literature on colorectal cancer associated cavernous sinus syndrome. Cavernous sinus metastasis from colorectal cancer is exceedingly rare. We report the second case of this entity with histopathologic confirmation, and the first case with concurrent perineural spread involving the trigeminal nerve. Cavernous sinus metastasis may represent a poor prognostic factor in colorectal cancer.

    Burkitt lymphoma (BL) is a type of non-Hodgkin lymphoma that arises in the B-cells. Cavernous sinus involvement is rare, especially in adults. Here we report an unusual case of a 30-year-old HIV-positive woman with BL and cavernous sinus syndrome who also had intense bilateral breast uptake, related to menstrual cycle. Fluorine-18 2-fluoro-2-deoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) has been found to be useful in the management of BL. A 30-year old female patient presented with a history of diplopia and headache. Magnetic resonance imaging revealed a large cavernous sinus mass. A bone marrow biopsy was done and demonstrated extensive marrow infiltration by Burkitt lymphoma. Further investigation detected the Epstein-Barr virus in her cerebrospinal fluid using qualitative polymerase chain reaction. 18F-FDG PET/CT imaging done revealed a hypermetabolic cavernous sinus mass, conglomerates of enlarged pelvic and para-aortic lymph nodes as well as diffuse bone marrow uptake. Intense bilateral breast uptake was noted coinciding with the start of menses. She was started on chemotherapy with adjuvant radiotherapy. After her first cycle of chemotherapy, repeat 18F-FDG PET/CT imaging revealed a marked reduction in the metabolic activity and size of the cavernous sinus mass and conglomerates of lymph nodes. The bone marrow activity was still visualized but less intense compared to the staging PET/CT. A cavernous sinus mass will rarely be the primary lesion in Burkitt's Lymphoma. Our case demonstrates the role of 18F-FDG PET/CT in the assessment of such cases to detect other primary areas of disease involvement. It is useful in accurate initial staging and monitoring of treatment response in patients with Burkitt's Lymphoma.

    Growth hormone-secreting pituitary adenomas in adults can result in severe craniofacial disfigurement and potentially fatal medical complications. Surgical resection leading to remission of the disease is dependent on complete surgical resection of the tumor. Lesions that invade the cavernous sinus may not be safely accessible via an endonasal transsphenoidal surgery (TSS), and the rates of biochemical remission of patients with residual disease vary widely in the literature. We conducted a meta-analysis to examine the prevalence of biochemical remission after TSS among patients with growth hormone-secreting pituitary adenomas with and without cavernous sinus invasion. Embase, PubMed, and Cochrane Library databases were searched for relevant publications. Fourteen studies with 972 patients with biochemically confirmed growth hormone-secreting pituitary adenomas were included in the meta-analysis. The overall remission prevalence under a fixed-effect model was 47.6% (95% CI = 40.8-54.4%) for patients with invasive macroadenomas (I2 = 74.6%, p cavernous sinus invasion (p = 0.01) and not from the size of adenomas among those without cavernous sinus invasion (p = 0.66). The prevalence of biochemical remission in patients with cavernous sinus invasion was lower than in patients without cavernous sinus invasion after TSS for acromegaly.

    A 1-year-old sexually intact male Korat cat was referred for ophthalmological consultation due to anisocoria. Mydriasis with external ophthalmoplegia and absence of pupillary light responses in the right eye and nasofacial hypalgesia were seen. Cavernous sinus syndrome (CSS) was suspected. Bilateral deformities of the jaw and phalangeal bones, severe spinal pain and abnormal conformation of the lumbar spine were also present. Radiographic examination revealed several mineralised masses in the appendicular and axial skeleton, indicative of multiple cartilaginous exostoses. For further investigation of the CSS-related neurological deficits, the cat underwent computed tomography (CT) examination of the skull. CT images revealed a non-vascularised, calcified, amorphous mass originating from the right lateral skull base and superimposing on the sella turcica. Based on the severity of diffuse lesions and owing to the clinical signs of extreme pain, the cat was euthanased. A diffuse skeletal and intracranial osteochondromatosis was diagnosed histologically.

    ABSTRACT Septic cavernous sinus thrombosis is a rare but serious complication of infection of the cavernous sinuses. There are no randomised, controlled trials of management of this condition and existing reviews of the literature are somewhat dated. The authors report a case with a favourable outcome and then present the findings of a literature review of the management of this condition. Outcome data suggest that corticosteroids are of equivocal benefit whereas antibiotics and anticoagulation are beneficial. PMID:27928417

    Background It has been hypothesized that a constitutionally narrow cavernous sinus might predispose individuals to cluster headache. Cavernous sinus dimensions, however, have never been assessed. Methods In this case-control study, we measured the dimensions of the cavernous sinus, skull base, internal carotid and pituitary gland with high-resolution T2-weighted magnetic resonance imaging in 25 episodic, 24 chronic and 13 probable cluster headache patients, 8 chronic paroxysmal hemicrania patients and 22 headache-free controls. Dimensions were compared between groups, correcting for age, sex and transcranial diameter. Results On qualitative inspection, no relevant pathology or anatomic variants that were previously associated with cluster headache or chronic paroxysmal hemicranias were observed in the cavernous sinus or paracavernous structures. The left-to-right transcranial diameter at the temporal fossa level (mean ± SD) was larger in the headache groups (episodic cluster headache: 147.5 ± 7.3 mm, p = 0.044; chronic cluster headache: 150.2 ± 7.3 mm, p cavernous sinus and surrounding structures between headache patients and controls. Conclusion Patients with cluster headache or chronic paroxysmal hemicrania had wider skulls than headache-free controls, but the proportional dimensions of the cavernous sinus were similar.

    Full Text Available The classical imaging gold-standard for this diagnosis is the presence of tumor lateral to the carotid artery. Seventeen patients with pituitary macroadenomas with intraoperative confirmation of cavernous sinus invasion were studied with MRI. Only 8 patients had tumor lateral to the carotid artery; 13 had tumor within the carotid syphon and all lacked the ring enhancement of the medial wall of the cavernous sinus. In 10 patients, widening of the posterior double leaflets of the cavernous sinus could be. All patients were operated by the transesphenoidal route. Only one patient was cured by surgery alone. Only 3 patients disclosing the above mentioned MRI features were identified in a series of 250 patients and did not have cavernous sinus invasion. The present criteria proved to be useful in the pre-operative diagnosis of cavenous sinus invasion and patients' counselling. Pre-operative diagnosis of cavernous sinus invasion of pituitary tumors has a great impact in the management of such patients.

    The authors present a retrospective series of their clinical experience in the treatment of cavernous dural arteriovenous fistulas (DAVF) by direct transorbital puncture of the cavernous sinus as an alternative to the endovascular approach. Between October 2012 and September 2014, eight patients harboring cavernous DAVF underwent percutaneous treatment by direct transorbital puncture of the cavernous sinus at three institutions. All patients presented with ocular symptoms. Standard endovascular approaches, including transvenous and transarterial routes, were primarily attempted without success in all cases. Direct puncture was performed through two different approaches, namely inferolateral and superomedial. The entry point was the inferior and superior eyelid, respectively. Embolization was performed with coils or Onyx (Covidien, Irvine, CA). Immediate and late angiographies were used to evaluate the occlusion of the fistula. Of the patients seven had complete occlusion of the cavernous DAVFs noted on the immediate and follow-up angiograms and one patient had residual filling but reduction of the shunt resulted in clinical improvement. None of the patients had worsening of neurological function. One case was complicated by inadvertent internal carotid puncture but without clinical manifestations. One patient experienced postoperative superior ophthalmic vein thrombosis. In very specific cases, when endovascular access is not possible or fails to occlude cavernous DAVF, direct transorbital puncture of the cavernous sinus was shown to be feasible, safe and very effective.

    Carotid cavernous sinus fistulas are a potentially severe pathology. Their basic standard treatment is an occlusion of the CCF performed by retrograde venous catheterization via the inferior petrous sinus. When the inferior petrous sinuses are occluded, other alternative venous routes are possible with various subsequent difficulties and risks. We report an original and safe method for endovascular treatment using submandibular puncture of the facial vein. We report 4 cases of patients with severe unilateral carotid cavernous sinus fistula associated with the occlusion of both inferior petrous sinuses. A submandibular surgical puncture of the ipsilateral inferior facial vein permitted the catheterization of the fistula. Complete occlusion of carotid cavernous sinus fistula was obtained by using a combination of microcoils and Onyx™. When inferior petrous sinuses are occluded, endovascular treatment of carotid cavernous sinus fistulas is more difficult. After reviewing the other treatment options reported in the literature and their respective advantages and adverse effects, we describe an original technique based on the surgical puncture of the ipsilateral facial vein. The occlusion of the fistula is then obtained by using a combination of microcoils and Onyx™. When the inferior petrous sinuses are occluded, an endovascular treatment for a carotid cavernous sinus fistula can be performed using an original and secure method. This method relies on a simple surgical puncture of the facial vein in the submandibular region, which then permits a retrograde catheterization of the carotid cavernous sinus fistula with no significant risk.

    OBJECTIVE Cavernous sinus hemangiomas (CSHs) are rare vascular tumors. A direct microsurgical approach usually results in massive hemorrhage and incomplete tumor resection. Although stereotactic radiosurgery (SRS) has emerged as a therapeutic alternative to microsurgery, outcome studies are few. Authors of the present study evaluated the role of SRS for CSH. METHODS An international multicenter study was conducted to review outcome data in 31 patients with CSH. Eleven patients had initial microsurgery before SRS, and the other 20 patients (64.5%) underwent Gamma Knife SRS as the primary management for their CSH. Median age at the time of radiosurgery was 47 years, and 77.4% of patients had cranial nerve dysfunction before SRS. Patients received a median tumor margin dose of 12.6 Gy (range 12-19 Gy) at a median isodose of 55%. RESULTS Tumor regression was confirmed by imaging in all 31 patients, and all patients had greater than 50% reduction in tumor volume at 6 months post-SRS. No patient had delayed tumor growth, new cranial neuropathy, visual function deterioration, adverse radiation effects, or hypopituitarism after SRS. Twenty-four patients had presented with cranial nerve disorders before SRS, and 6 (25%) of them had gradual improvement. Four (66.7%) of the 6 patients with orbital symptoms had symptomatic relief at the last follow-up. CONCLUSIONS Stereotactic radiosurgery was effective in reducing the volume of CSH and attaining long-term tumor control in all patients at a median of 40 months. The authors' experience suggests that SRS is a reasonable primary and adjuvant treatment modality for patients in whom a CSH is diagnosed.

    To describe clinical characteristics, imaging findings, morbidity, and mortality in a single-center cohort of 12 pediatric cavernous sinus thrombosis cases and to review all cases available in recent English literature. Clinical data and radiographic studies on 12 cases from our institution were analyzed retrospectively. A literature search and review was conducted, with additional cases pooled with the new cohort for an aggregate analysis. Twelve cases of cavernous sinus thrombosis in children from the Children's Hospital of Philadelphia between January 1, 2000, and December 31, 2013, were reviewed. All patients survived to discharge; 3 of 12 (25%) experienced neurologic morbidity. Contrast-enhanced MRI and contrast-enhanced head CT were 100% sensitive for detecting cavernous sinus thrombosis, while noncontrast time-of-flight magnetic resonance venography (TOF MRV) and noncontrast head CT were 0% sensitive. Literature review produced an additional 40 cases, and the aggregate mortality rate was 4 of 52 (8%) and morbidity rate was 10 of 40 (25%). Outcomes did not vary by treatment or with unilateral vs bilateral cavernous sinus involvement. There was a trend toward worse outcomes with fungal infections. Our case series demonstrates low morbidity and mortality with early, aggressive surgical, antimicrobial, and anticoagulation therapies. Although anticoagulation and surgery were not associated with significantly different outcomes, more study is needed. © 2015 American Academy of Neurology.

    Cavernous sinus thrombosis is a rare but serious complication of sphenoid aspergillosis. The rarity of this pathology makes its diagnostic very difficult on a clinical, biological and radiological sense. The authors present a case of cavernous sinus thrombosis with ipsilateral internal carotid artery thrombosis secondary to a non-invasive sphenoid aspergillosis in an immunocompetent host, responsible of a cavernous syndrome associated to a Claude Bernard Horner syndrome. One year after surgery, the patient is still asymptomatic without recurrence. Diagnostic modalities are detailed and several management of this pathology are compared. Surgery is essential in a diagnostic and therapeutic sense. There is no evidence of the interest of adjuvant therapies such as antibiotic and anticoagulation. Concerning the antifungal treatment, the attitude towards a non-invasive sphenoid aspergillosis in an immunocompetent host is unclear. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Case Report: The patient was referred to our unit 12 months following uneventful right dacryocystorhinostomy for nasolacrimal duct obstruction. This had been complicated by the formation of a significant canthal swelling 6 months later, which had been excised at that time. The symptom of nasolacrimal duct obstruction and scar recurrence prompted the referral to our unit. Examination and biopsy confirmed a malignancy. Despite extensive surgery, including concurrent radical neck dissection and parotidectomy, within 6 months, her mucoepidermoid carcinoma was found to have spread to the cavernous sinus, restricting blood flow from the carotid and causing an abducens nerve palsy. Though deemed inoperable at first, Gamma Knife stereotactic radiosurgery was sought as treatment for her disease, resulting in a good outcome 4 years after surgery. Conclusion: Experience from this case suggests the importance of considering malignancy as a cause in young patients when presenting with nasolacrimal duct obstruction. In such cases, and perhaps for all patients, biopsy specimens should be submitted as many tumours are found incidentally at the time of dacryocystorhinostomy. Whilst the external approach to dacryocystorhinostomy may identify abnormal anatomy intraoperatively, prompting biopsy, this is less likely with an endonasal approach where osteotomy precedes sac visualisation. The endonasal approach may therefore be less appropriate in such cases where malignancy is suspected as osteotomy may aid in the spread.

    Introduction: The purpose of this study was to evaluate the single-centre experience with transvenous coil treatment of dural carotid-cavernous sinus fistulas. Methods: Between November 1991 and December 2005, a total of 141 patients (112 female) with dural carotid-cavernous sinus fistula underwent 161 transvenous treatment sessions. The patient files and angiograms were analysed retrospectively. Clinical signs and symptoms included chemosis (94%), exophthalmos (87%), cranial nerve palsy (54%), increased intraocular pressure (60%), diplopia (51%), and impaired vision (28%). Angiography revealed in addition cortical drainage in 34% of the patients. Partial arterial embolization was carried out in 23% of the patients. Transvenous treatment comprised in by far the majority of patients complete filling of the cavernous sinus and the adjacent segment of the superior and inferior ophthalmic vein with detachable coils. Complete interruption of the arteriovenous shunt was achieved in 81% of the patients. A minor residual shunt (without cortical or ocular drainage) remained in 13%, a significant residual shunt (with cortical or ocular drainage) remained in 4%, and the attempted treatment failed in 2%. There was a tendency for ocular pressure-related symptoms to resolve rapidly, while cranial nerve palsy and diplopia improved slowly (65%) or did not change (11%). The 39 patients with visual impairment recovered within the first 2 weeks after endovascular treatment. After complete interruption of the arteriovenous shunt, no recurrence was observed. The transvenous coil occlusion of the superior and inferior ophthalmic veins and the cavernous sinus of the symptomatic eye is a highly efficient and safe treatment in dural carotid-cavernous sinus fistulas. In the majority of patients a significant and permanent improvement in clinical signs and symptoms can be achieved. (orig.)

    To investigate the imaging features of cavernous sinus cavernous hemangioma (CSCH) and evaluate the therapeutic effect of Gamma Knife radiosurgery (GKRS) in treatment of CSCH. Fifteen patients with CSCH treated by GKRS in our institute, including 6 males and 9 females, age range 20-77 years old, were analyzed retrospectively. Three of them were given craniotomies as the initial therapy. All cases had performed conventional and contrast-enhanced MRI and 5 patients underwent dynamic enhanced MRI preoperatively. In 6 cases, the multi-directional continuous data of axial, coronal and sagittal enhanced MRI were acquired. Three cases performed digital subtraction angiography (DSA) simultaneously. The diagnoses of lesions were determined mainly depending on typical imaging features. In 3 patients, the diagnoses of CSCH were confirmed histopathologically. The radiation dosimetry was done with a goal of conformal and selective coverage of the lesion with a 50% prescription isodose line. The mean marginal dose constituted 13.4 Gy (range 10-16 Gy). After GKRS was performed, all patients were arranged regular clinical and MRI follow-up every 6 months during the first 12 months, and once per year thereafter. On MRI, the lesions were typically demonstrated as iso/hypo-intensities on T1WI and remarkable hyper-intensities on T2WI, and apparent homogeneous enhancement. The phenomenon of dynamic enhancement was found in 11 cases. The progressive enhancing process from heterogeneous to uniform was displayed in the 5 patients performed same-slice dynamic MRI, including imaging characteristics of 'edge to center' enhancement in 2 case. In the other 6 cases, the delayed homogeneous enhancement of lesion was observed. Ten patients obtained radiological follow-up results after GKRS. Reviewing the follow-up data of 8 patients during the period of 3-6 months, the lesions were apparently shrunk in 5 patients with shrinkage rate of 20.8-46.8%. In 4 patients with imaging follow-up during the

    To report the first case of bilateral cavernous sinus thromboses and bilateral intraorbital abscesses secondary to Streptococcus milleri. Single interventional case report. The findings of the ophthalmic evaluation, radiographic imaging, medical and surgical intervention, specimen cultures, and clinical course were analyzed. A 17-year-old female had bilateral proptosis, decreased vision in the left eye, and altered mental status at presentation. An orbital compartment syndrome developed in the left eye and purulent material was present after lateral canthotomy, suggestive of an intraorbital abscess. Magnetic resonance imaging (MRI) scans revealed bilateral cavernous sinus thromboses, and subsequent computed tomographic (CT) scans revealed bilateral intraorbital abscesses in the setting of acute ethmoid and sphenoid sinusitis. Antibiotic treatment and surgical drainage of the orbital abscess and sinuses was performed, and specimen cultures revealed S. milleri. After surgery, the patient experienced hearing loss and a right internal capsule infarct, in addition to complete vision loss in the left eye. A second intraorbital abscess developed in the right eye and was drained surgically. The vision remained 20/20. Streptococcus milleri is a virulent organism with a propensity to form abscesses in multiple areas of the body and should be considered as a possible etiologic agent in abscess formation of the orbit and cavernous sinus thrombosis.

    Sinus cavernosi, or the cavernous sinus, was coined by Jacques Bénigne Winslow in the 18th century. Among the neurosurgeons and the modern-day neuroanatomists, Winslow is mainly known for erroneously using the term cavernous sinus. As the anatomical understanding of the parasellar space advanced during the next 200 years, it was unclear as to why Winslow compared this space in the brain with that of a male reproductive organ (corpus cavernosum). Our primary objective was to study the historical treatise on anatomy written by Winslow in the 18th century and analyze his anatomical dissections and nomenclature for the parasellar compartment. In addition, his pertinent contributions to neuroscience are highlighted in this vignette. Copyright © 2014 Elsevier Inc. All rights reserved.

    Cavernous sinus hemangioma is a rare and complex vascular tumor. A direct microsurgical approach usually results in massive hemorrhage. Stereotactic radiosurgery has emerged as a treatment alternative to microsurgery. To conduct a meta-analysis assessing the effect and complications of stereotactic radiosurgery in cavernous sinus hemangioma, a systematic review and meta-analysis of all cases of cavernous hemangioma in the cavernous sinus treated with stereotactic radiosurgery was performed. The search revealed ten papers with a total enrollment of 59 patients. Tumor size ranged from 1.5-51.4 cm(3) (mean 9.6 cm(3)). The mean follow-up period was 49.2 months (range 6-156 months). The most recent MR images demonstrated remarkable tumor shrinkage in 40 patients (67.8%), partial shrinkage in 15 patients (25.4%), and no change in four patients (6.8%). There was no significant correlation between lesion volume and tumor shrinkage. Patients with remarkable tumor shrinkage received higher doses than those with partial or no change tumor shrinkage (P = 0.031). Thirteen patients (22.0%) had no cranial nerve impairments before stereotactic radiosurgery. Among those 46 patients with cranial nerve impairments before stereotactic radiosurgery, complete resolution was achieved in seven patients and improvement in 28, and these impairments remained essentially unchanged in 11 patients. Only one patient had additional trigeminal nerve disturbance. There is no statistical significance in tumor control between patients treated with or without surgery (P = 0.091). The meta-analysis suggests stereotactic radiosurgery avoids the complications associated with attempted microsurgical resection. Stereotactic radiosurgery is an alternative for cavernous sinus hemangiomas confirmed by typical imaging.

    OBJECTIVE Exposure of the cavernous sinus is technically challenging. The most common surgical approaches use well-known variations of the standard frontotemporal craniotomy. In this paper the authors describe a novel ventral route that enters the lateral wall of the cavernous sinus through an interdural corridor that includes the removal of the greater sphenoid wing via a purely endoscopic transorbital pathway. METHODS Five human cadaveric heads (10 sides) were dissected at the Laboratory of Surgical NeuroAnatomy of the University of Barcelona. To expose the lateral wall of the cavernous sinus, a superior eyelid endoscopic transorbital approach was performed and the anterior portion of the greater sphenoid wing was removed. The meningo-orbital band was exposed as the key starting point for revealing the cavernous sinus and its contents in a minimally invasive interdural fashion. RESULTS This endoscopic transorbital approach, with partial removal of the greater sphenoid wing followed by a "natural" ventral interdural dissection of the meningo-orbital band, allowed exposure of the entire lateral wall of the cavernous sinus up to the plexiform portion of the trigeminal root and the petrous bone posteriorly and the foramen spinosum, with the middle meningeal artery, laterally. CONCLUSIONS The purely endoscopic transorbital approach through the meningo-orbital band provides a direct view of the cavernous sinus through a simple and rapid means of access. Indeed, this interdural pathway lies in the same sagittal plane as the lateral wall of the cavernous sinus. Advantages include a favorable angle of attack, minimal brain retraction, and the possibility for dissection through the interdural space without entering the neurovascular compartment of the cavernous sinus. Surgical series are needed to demonstrate any clinical advantages and disadvantages of this novel route.

    Studying the three-dimensional (3D) anatomy of the cavernous sinus is essential for treating lesions in this region with skull base surgeries. Cadaver dissection is a conventional method that has insurmountable flaws with regard to understanding spatial anatomy. The authors' research aimed to build an image model of the cavernous sinus region in a virtual reality system to precisely, individually and objectively elucidate the complete and local stereo-anatomy. Computed tomography and magnetic resonance imaging scans were performed on 5 adult cadaver heads. Latex mixed with contrast agent was injected into the arterial system and then into the venous system. Computed tomography scans were performed again following the 2 injections. Magnetic resonance imaging scans were performed again after the cranial nerves were exposed. Image data were input into a virtual reality system to establish a model of the cavernous sinus. Observation results of the image models were compared with those of the cadaver heads. Visualization of the cavernous sinus region models built using the virtual reality system was good for all the cadavers. High resolutions were achieved for the images of different tissues. The observed results were consistent with those of the cadaver head. The spatial architecture and modality of the cavernous sinus were clearly displayed in the 3D model by rotating the model and conveniently changing its transparency. A 3D virtual reality model of the cavernous sinus region is helpful for globally and objectively understanding anatomy. The observation procedure was accurate, convenient, noninvasive, and time and specimen saving.

    To investigate the indications of the pretemporal transcavernous approach for cavernous sinus tumors resection and design individually tailored surgery according to the extent of tumors and operation requirements. A retrospective analysis of clinical data, surgical outcomes and complications in a series of 31 cases with cavernous sinus tumor operated via the individually tailored pretemporal transcavernous approach between May 2012 and September 2015 in Department of Neurosurgery, Xiangya Hospital, Central South University. There were 13 male and 18 female patients, aging from 17 to 67 years with a mean of (41±14) years. The patients included 18 cases of shwannomas, 4 cases of meningiomas, 3 cases of cavernous hemangiomas, 2 cases of invasive pituitary adenomas, 1 case of chordoma, 1 case of chondroma, 1 case of recurrent teratoma, 1 case of metastatic nasopharyngeal carcinoma. The first followed-up visit was on the 3(rd) month after surgery, and if tumor progression or recurrence was observed on MRI, the Gamma knife treatment was recommended, the patient was followed up every 6 months, otherwise the patient was followed up again 6 months later, then, every 12 months. Gross total removal of tumors was achieved in 22 cases of 31 patients (71.0%), containing 17 cases of shwannomas, 3 cases of hemangiomas, 1 case of chondroma, 1 case of teratoma; subtotal removal in 6 cases (19.3%), including 3 cases of meningiomas, 1 case of pituitary adenoma, 1 case of chordoma, 1 case of metastatic carcinoma; partial removal in 3 cases (9.7%), comprising 1 case of meningioma, 1 case of recurrent shwannoma, 1 case of recurrent pituitary adenoma. The symptoms of cranial never aggravated in 5 cases, the new postoperative cranial never palsy was observed in 7 cases. There was no surgical mortality, intracranial hematoma, intracranial infection and cerebrospinal fluid leakage cases, ect. Twenty-eight cases were followed up for more than 3 months (3 to 40 months), 1 case of chordoma had

    The goal of dural arteriovenous fistula of the cavernous sinus treated with coils through ultrasound-guided access to the facial vein is to interrupt the fistulous communications and decrease the pressure in the cavernous sinus and consequently in the ophthalmic veins. The traditional approach in the treatment of these fistulae is transvenous endovascular occlusion of the cavernous sinus. Transvenous embolization has been proven to be safe and can provide complete and permanent occlusion of the fistula in a single session. The most commonly used venous pathway is the inferior petrosal sinus, but, if it is inaccessible, then, the superior ophthalmic vein is considered; nonetheless, it can require a surgical exposure. Other pathways include the transfemoral transfacial vein. An arterial approach is considered usually when venous approach pathways fail. Arterial occlusion of feeders supplying the fistula is associated with a greater risk of embolic complications. We report a case of dural arteriovenous fistula of the cavernous sinus treated with coils through ultrasound-guided access to the facial vein. We propose an alternative pathway when the conventional transvenous approach through the inferior petrosal sinus is excluded. An ultrasound-guided facial vein approach can be considered as a direct and safe alternative to reach the cavernous sinus and obtain exclusion of the fistula. Copyright © 2016 Elsevier Inc.

    A 51-year-old woman with left proptosis, diplopia, headache, and nausea was found to have bilateral intraorbital abscesses, left superior ophthalmic vein thrombosis, bilateral cavernous sinus thromboses, and a left temporal lobe intracerebral abscess. Because the paranasal sinuses were unaffected, a dental origin was suspected and confirmed. The causative organism was Streptococcus milleri. Aggressive surgical intervention included bilateral orbital abscess drainage and dental extraction, and medical therapy included intravenous metronidazole, ceftriaxone, heparin, and methylprednisolone. A left sixth cranial nerve paresis was the only long-term sequela.

    The zenith of surgical interest in the cavernous sinus peaked in the 1980s, as evidenced by reports of 10 surgical triangles that could access the contents of the lateral sellar compartment (LSC). However, these transcranial approaches later became marginalized, first by radiosurgery's popularity and lower morbidity, and then by clinical potential of endoscopic corridors noted in several qualitative studies. Our anatomic study, taking a contemporary look at the medial extra-sellar corridor, gives a detailed qualitative-quantitative analysis for its use with increasingly popular endoscopic endonasal approaches to the cavernous sinus. In 20 cadaveric specimens, we re-examined the anatomic landmarks of the medial corridor into the LSC with qualitative descriptions and measurements. An illustrative case highlights a recurrent symptomatic pituitary adenoma that invaded the cavernous sinus approached through the medial corridor. The corridor's shape varied from tetrahedron to hexahedron. Comparing right and left sides, width averaged 3.6 ± 4.5 mm and 4.0 ± 4.4 mm, and height averaged 2.3 mm and 2.1 mm, respectively. About 35% of sides showed ample space for access into the cavernous sinus. Our case report of successful outcome lends support for the safety and efficacy of this endoscopic approach. Our re-examination of this particular surgical access into the LSC refines the understanding of the medial extra-sellar corridor as a main endoscopic access route to this compartment. Achieving safe access to the contents of the LSC, this 11th triangle is clinically relevant and potentially superior for select lesions in this region. Copyright © 2016 Elsevier Inc.

    Endovascular embolization is the treatment of choice for carotid-cavernous fistulas (CCFs), but failure to catheterize the cavernous sinus may occur as a result of vessel tortuosity, hypoplasia, or stenosis. In addition to conventional transvenous or transarterial routes, alternative approaches should be considered. The authors present a case in which a straightforward route to the CCF was accessed via transsphenoidal puncture of the cavernous sinus in a neurosurgical hybrid operating suite. This 82-year-old man presented with severe chemosis and proptosis of the right eye. Digital subtraction angiography revealed a Type B CCF with a feeding artery arising from the meningohypophyseal trunk of the right cavernous segment of the internal carotid artery. The CCF drained through a thrombosed right superior ophthalmic vein that ended deep in the orbit; there were no patent sinuses or venous plexuses connecting to the CCF. An endoscope-assisted transsphenoidal puncture created direct access to the nidus for embolization. Embolic agents were deployed through the puncture needle to achieve complete obliteration. Endoscope-assisted transsphenoidal puncture of the cavernous sinus is a feasible alternative to treat difficult-to-access CCFs in a neurosurgical hybrid operating suite.

    We performed this retrospective study to investigate the outcomes of patients with hemangioma of the cavernous sinus after fractionated radiotherapy. We analyzed 10 patients with hemangioma of the cavernous sinus who were treated with conventional radiotherapy between January 2000 and December 2016. The median patient age was 54 years (range, 31–65 years), and 8 patients (80.0%) were female. The mean hemangioma volume was 34.1 cm{sup 3} (range, 6.8–83.2 cm{sup 3}), and fractionated radiation was administered to a total dose of 50–54 Gy with a daily dose of 2 Gy. The median follow-up period was 6.8 years (range, 2.2–8.8 years). At last follow-up, the volume of the tumor had decreased in all patients. The average tumor volume reduction rate from the initial volume was 72.9% (range, 18.9–95.3%). All 10 of the cranial neuropathies observed before radiation therapy had improved, with complete symptomatic remission in 9 cases (90%) and partial remission in 1 case (10%). No new acute neurologic impairments were reported after radiotherapy. One probable compressive optic neuropathy was observed at 1 year after radiotherapy. Fractionated radiotherapy achieves both symptomatic and radiologic improvements. It is a well-tolerated treatment modality for hemangiomas of the cavernous sinus.

    Full Text Available Cavernous angiomas (cavernomas of the cavernous sinus are uncommon, with only scattered reports in literature. Unlike their parenchymatous counterparts, they are intensely enhancing para-sellar masses, iso/hypointense in T1- and hyperintense in T2-weighted images. Differential diagnosis with para-sellar meningiomas and schwannomas can be difficult. We report three cases of this condition, describing findings of diffusion-weighted imaging in this kind of lesion for the first time in literature.Angiomas cavernosos (cavernomas do seio cavernoso são lesões incomuns, com poucos relatos na literatura especializada. Ao contrário dos cavernomas parenquimatosos, são massas para-selares intensamente captantes, isointensas a hipointensas em T1 e hiperintensas em T2 nas imagens de ressonância magnética. O diagnóstico diferencial com meningiomas e schwannomas para-selares pode ser difícil. Relatamos os achados de imagem de três casos desta entidade, descrevendo os achados da ressonância magnética ponderada em difusão neste tipo de lesão pela primeira vez na literatura.

    AIM To elucidate the clinical, magnetic resonance imaging (MRI), pathological features of these lesions and asses the incremental value of diffusion-weighted imaging (DWI) in diagnosing them. METHODS Fifteen consecutive patients (11 females and 4 males; mean age 40.93 years; age range 13-63 years) with cavernous sinus hemangiomas (CSH) who underwent examination between November 2008 and May 2016 were included for the analysis. MRI, clinical and surgical findings of each patient was retrospectively reviewed. DWI were also analysed and mean-apparent diffusion coefficient (ADC) value was calculated. Eleven patients underwent surgical removal of the lesion and 2 patients had biopsy only. Diagnosis of CSH was confirmed histologically in 13 patients. RESULTS Eleven patients (73%) presented with headaches and 10 (66%) had cranial nerve involvement. Extra cavernous sinus extension was noted in 14 (94%). Surgery was performed in 13 (87%) and post-operative radiation was given to 4 (28%) patients. Thirteen patients remained asymptomatic on follow up. Three conspicuous imaging features were highly suggestive of the diagnosis: Lack of diffusion restriction (100%), homogeneous hyperintensity on T2 weighted image sequences (93.3%) and intense post-contrast enhancement (100%). The mean ADC was 1.82 × 10-3 ± 0.2186 cm2/s. CONCLUSION T1-weighted hypointensity with homogeneous hyperintensity on T2-weighted sequences, intense enhancement and absence of hemosiderin within the lesion on GRE sequence favour the diagnosis. Facilitated diffusion on DWI differentiates CSH from other solid cavernous sinus lesions and significantly improves the diagnostic accuracy, a critical factor for planning surgery. PMID:28932362

    Cavernous sinus (CS) fistulas are classified into traumatic and spontaneous. Traumatic carotid-cavernous fistulas (CCFs) are usually direct internal carotid artery (ICA) high-flow fistulas; whereas spontaneous CCFs are usually dural, low-flow fistulas and generally possess less severe symptoms than direct carotid-cavernous fistulas. This study involved 34 patients who were classified into 2 groups: Group A included 26 patients with direct carotid-cavernous fistula; and Group B included 8 patients with indirect dural cavernous fistula. All patients had ocular manifestations. One patient had subarachnoid hemorrhage. Coils were used alone in 19 cases of direct fistula and in 1 case of dural fistulas. Coils and Onyx (Covidien, Mansfield, MA, USA) were used in 7 cases of direct fistula and in 2 cases of dural fistulas. Onyx alone was used to treat 5 cases with dural fistulas but none of the cases with direct fistulas. Covered stents and coils were used in 2 cases of direct fistulas. All patients in both groups showed full recovery of their clinical signs and symptoms. Only 1 procedure-related complication was observed (3%) in which a patient had an embolic event and trigeminal dysesthesia as a result of Onyx reflux through external carotid artery-ICA anastomosis. Coils are superior solid embolic agents used for the treatment of direct high-flow fistulas, while Onyx is more valuable in dural low-flow CCF. Onyx shortens the procedure time and decreases procedure cost. Onyx injection inside the CS proper through the transarterial or transvenous route may be safer than Onyx injected inside dural arteries supplying the CS. However, more cases are needed to determine this. Copyright © 2015 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    We report a 12-year-old boy who presented with incomplete right ophthalmoplegia, exophthalmos and headache. Initial CT and MRI revealed a mass in the right cavernous sinus. During tumour work-up, CT identified additional tumour within the mediastinum. Biopsy of the mediastinal lesion identified Burkitt's lymphoma. We report on this case because radiologists and clinicians should be alerted to identify sites of primary Burkitt's lymphoma outside of the central nervous system if clinical symptoms indicate, or imaging shows, CNS lesions. Primary CNS involvement in Burkitt's lymphoma is rare. (orig.)

    Benign lesion interior to the cavernous sinus (CS) is very rare. In this series we found nonneoplastic lymphatic aggregation and osteoclastoma inside the CS which is very rare and probably not reported in literature. One interesting postoperative complaint of feeling of tickling down of warm water under the skin forehead was found in the patient of inflammatory disease of CS which is not reported in literature. Here we also describe our experiences of microsurgical management of series of benign lesions inside the CS. Benign mass originated from the content of CS or inner side of walls of CS, confirmed peroperatively were included in this series. Prospectively recorded data of microsurgical management was retrogradely studied. Total number of patient was 12. Patient's age range was 30-60 years. Follow-up range was 60 months to 19 months. Three was nonneoplastic lesion (tuberculosis, inflammatory and nonneoplastic lymphoid infiltration). Among the 9 neoplastic lesions, two hemangiomas, two meningiomas, three 6(th) nerve schwannomas, one osteoclastoma and one epidermoid tumor. Middle cranial fossa-subtemporal extradural approach was used in 9 cases and in two cases extended middle fossa zygomatic approach. New postoperative 3(rd) nerve palsy developed in 5 cases all recovered completely except one. In seven patients 6(th) nerve palsy developed after operation; only one recovered. Postoperatively simultaneous 3(rd), 4(th) and 6(th) nerve palsy developed in four cases. One interesting postoperative complaint of feeling of tickling down of warm water under the skin of left sided forehead was found in the patient of inflammatory disease of CS. Mortality was nil. Total resection was done in 9 cases. There was no recurrence till last follow-up. Though decision for microsurgical removal of such lesions is not straight forward. Probably microsurgery is the best option in treating such benign lesions though it may associate with some permanent cranial nerve palsy.

    In a patient with progressive ophthalmological problems, including uncontrolled intraocular pressure related to a cavernous sinus dural arteriovenous fistula, urgent intervention may be necessary to prevent permanent visual loss. We report a case in which inadequate transarterial embolisation and lack of access for transvenous catheterisation, including a direct approach through the superior ophthalmic vein, preceded percutaneous puncture of the superior ophthalmic vein deep within the orbit, permitting venous occlusion without complications. This case demonstrates that deep orbital puncture of the vein is feasible for occlusion of a cavernous sinus dural arteriovenous fistula. (orig.)

    Purpose: Patients with cavernous sinus meningiomas (CSM) have an elevated risk of surgical morbidity and mortality. Recurrence is often observed after partial resection. Stereotactic radiosurgery (SRS), either alone or combined with surgery, represents an important advance in CSM management, but long-term results are lacking. Methods and Materials: A total of 88 CSM patients, treated from January 1991 to December 2005, were retrospectively reviewed. The mean follow-up was 86.8 months (range, 17.1-179.4 months). Among the patients, 22 were followed for more than 10 years. There was a female predominance (84.1%). The age varied from 16 to 90 years (mean, 51.6). In all, 47 patients (53.4%) received SRS alone, and 41 patients (46.6%) had undergone surgery before SRS. A dose of 14 Gy was prescribed to isodose curves from 50% to 90%. In 25 patients (28.4%), as a result of the proximity to organs at risk, the prescribed dose did not completely cover the target. Results: After SRS, 65 (73.8%) patients presented with tumor volume reduction; 14 (15.9%) remained stable, and 9 (10.2%) had tumor progression. The progression-free survival was 92.5% at 5 years, and 82.5% at 10 years. Age, sex, maximal diameter of the treated tumor, previous surgery, and complete target coverage did not show significant associations with prognosis. Among the 88 treated patients, 17 experienced morbidity that was related to SRS, and 6 of these patients spontaneously recovered. Conclusions: SRS is an effective and safe treatment for CSM, feasible either in the primary or the postsurgical setting. Incomplete coverage of the target did not worsen outcomes. More than 80% of the patients remained free of disease progression during long-term follow-up.

    This case illustrates the importance of prompt assessment and treatment of orbital cellulitis. In fact the ocular signs and symptoms may be associated with systemic complications which should be investigated and identified as soon as possible to avoid a poor prognosis. A 46-year-old white woman presented to our emergency room with proptosis, ophthalmoplegia, and conjunctival chemosis of her left eye. An ophthalmologist, having diagnosed orbital cellulitis in her left eye, suspected a cavernous sinus thrombosis. Hematochemical and radiological examinations confirmed the cavernous sinus thrombosis and also showed septic pulmonary embolism. A blood culture indicated Streptococcus constellatus, which is a member of the Peptostreptococcus family, a saprophyte of the oral mucosa that can be pathogenic in immunocompromised persons. The odontogenic origin was then confirmed by dental radiography which showed a maxillary abscess. Her eye signs regressed after antibiotic and anticoagulant therapy. This complex case shows the importance of a multidisciplinary approach for the management of orbital cellulitis, for the prompt diagnosis and treatment of eye injuries and possible complications, so as to avoid serious and permanent sequelae.

    Full Text Available Septic cavernous sinus thrombosis (CST is an uncommon clinical syndrome. Although Staphylococcus aureus (S aureus is the most common bacterial pathogen causing CST, it is infrequent as a cause of meningitis. We report the first case of CST and meningitis from Bengaluru, Karnataka, caused by community-acquired epidemic methicillin resistant Staphylococcus aureus-15 (EMRSA-15, in a previously healthy individual without known risk factors; the patient recovered following treatment with vancomycin. The isolate was genotyped as belonging to staphylococcal cassette chromosome mec type IV and sequence type 22 and carried the panton-valentine leucocidin gene. It is the first Indian EMRSA-15 disease isolate from a case of meningitis. EMRSA-15 has been a major problem in hospitals in UK and it is a cause for great concern in Indian hospitals too.

    OBJECTIVE Tumors with cavernous sinus (CS) invasion represent a neurosurgical challenge. Increasing application of the endoscopic endonasal approach (EEA) requires a thorough understanding of the CS anatomy from an endonasal perspective. In this study, the authors aimed to develop a surgical anatomy-based classification of the CS and establish its utility for preoperative surgical planning and intraoperative guidance in adenoma surgery. METHODS Twenty-five colored silicon-injected human head specimens were used for endonasal and transcranial dissections of the CS. Pre- and postoperative MRI studies of 98 patients with pituitary adenoma with intraoperatively confirmed CS invasion were analyzed. RESULTS Four CS compartments are described based on their spatial relationship with the cavernous ICA: superior, posterior, inferior, and lateral. Each compartment has distinct boundaries and dural and neurovascular relationships: the superior compartment relates to the interclinoidal ligament and oculomotor nerve, the posterior compartment bears the gulfar segment of the abducens nerve and inferior hypophyseal artery, the inferior compartment contains the sympathetic nerve and distal cavernous abducens nerve, and the lateral compartment includes all cavernous cranial nerves and the inferolateral arterial trunk. Twenty-nine patients had a single compartment invaded, and 69 had multiple compartments involved. The most commonly invaded compartment was the superior (79 patients), followed by the posterior (n = 64), inferior (n = 45), and lateral (n = 23) compartments. Residual tumor rates by compartment were 79% in lateral, 17% in posterior, 14% in superior, and 11% in inferior. CONCLUSIONS The anatomy-based classification presented here complements current imaging-based classifications and may help to identify involved compartments both preoperatively and intraoperatively.

    Full Text Available Objective To investigate the clinical manifestations and pathological features of parotid gland papillary acinic cell carcinoma metastasis to left cavernous sinus. Methods The clinical manifestations, pathological features and differential diagnosis were studied in one case of parotid papillary acinic cell carcinoma metastasis to left cavernous sinus. Related literatures were also reviewed. Results The patient was a 50-year-old female who presented paroxysmal dizziness for 5 months and blurred vision in her left eye for 10 months. The MRI examination showed left parasellar space-occupying mass in the cavernous sinus. In operation, the tumor was located in the superior wall of left cavernous sinus, soft and red-grey in color, with abundant blood supply. The histomorphological examination revealed the tumor cells were arranged in solid, acinar or papillary pattern. The tumor cells were large, with eosinophilic cytoplasm, round or oval nuclei and small nucleoli. Immunohistochemical staining found that the tumor cells expressed cytokeratin (CK, epithelial membrane antigen (EMA, vimentin (Vim and S-100 protein (S-100, and showed weak positive expression of glial fibrillary acidic protein (GFAP and focal positive expression of P53 protein. Ki-67 labeling index was about 5%-10% . The tumor cells were negative for neuroendocrine markers and pituitary hormone protein markers. This case was difficult to differentiate from other primary intracalvarium tumors, including papillary meningioma, papillary tumor of choroid plexus, papillary ependymoma, papillary glioneuronal tumors as well as chordoma. According to the medical history and the comparison of histomorphology and immunophenotyping between parotid gland tumor cells and left cavernous sinus tumor cells, the final diagnosis was metastatic papillary parotid acinar cell carcinoma of the left cavernous sinus. The patient was followed for 21 months and no recurrence was seen. Conclusion It is very rare and

    Non-functioning pituitary adenomas (NFPA) invading into the cavernous sinus are surgically challenging. To decrease recurrence rate, surgeon makes a strong endeavor to resect tumor gross totally. However, gross total resection (GTR) is difficult to achieve with cavernous sinus invasion. Recently, a new classification system for cavernous invasion of pituitary adenomas was suggested. The aim of this study is to validate this new classification system and to identify limitations and considerations in designing treatment strategies for patients with NFPA involving the cavernous sinus. Between January 2000 and January 2012, 275 patients who underwent operation for NFPA were enrolled in the study. Median age was 50 years (15-79 years). There were 145 males and 130 females. The median follow-up duration was 4 years (range 1-12.5 years). Related to extent of tumor removal, GTR was obtained in 184 patients (66.9%), near total resection (NTR) was obtained in 45 patients (16.3%), and sub-total resection (STR) was obtained in 46 patients (16.7%) of a total 275 patients. There were statistically significant differences between the extent of resection and the new Knosp classification (pcavernous-invading adenomas.

    Purpose: To analyze own long-term results with fractionated stereotactic radiotherapy (FSRT) in patients with benign meningiomas of the cavernous sinus and to review the literature on these rare lesions. Patients and Methods: 57 patients were treated with FSRT for benign meningiomas of the cavernous sinus between 01/1990 and 12/2003 at the authors' institution. Histology was WHO grade I in 28/57 lesions, and undetermined in 29/57 lesions. 29 patients received radiotherapy as primary treatment, ten following surgery, and 18 patients were irradiated for recurrent disease. Median target volume was 35.2 cm{sup 3}. Median total dose was 57.6 Gy with 1.8 Gy per fraction. 51/57 patients showed clinical symptoms before radiotherapy like reduced vision (n=19), diplopia (n=25), or trigeminal hyp-/dysesthesia (n=17). Results: Median follow-up period was 6.5 years. 50/57 patients were followed for >36 months. Overall local tumor control was 100%. 39/57 patients had stable disease based on CT/MRI, while 18/57 had a partial remission of tumor volume. Overall survival for patients with WHO grade I meningiomas was 95.5% after 5 and 10 years. Two patients died 2.8 and 4.1 years after radiotherapy due to cardiac failure. In 11/57 patients, preexisting neurologic deficits improved. There was one patient with recurrent hyperlacrimation of one eye on the side of the irradiated meningioma. Three patients complained about subjective visual deterioration after FSRT without any objective findings in an ophthalmologic examination. No late toxicity RTOG{>=} III was seen. Conclusion: These data demonstrate that FSRT is an effective and safe treatment modality for local control of benign cavernous sinus meningiomas with a minimal risk of significant late toxicity.

    OBJECTIVE To determine effects of anesthesia on plasma concentrations and pulsatility of ACTH in samples obtained from the cavernous sinus and jugular vein of horses. ANIMALS 6 clinically normal adult horses. PROCEDURES Catheters were placed in a jugular vein and into the cavernous sinus via a superficial facial vein. The following morning (day 1), cavernous sinus blood samples were collected every 5 minutes for 1 hour (collection of first sample = time 0) and jugular venous blood samples were collected at 0, 30, and 60 minutes. On day 2, horses were sedated with xylazine hydrochloride and anesthesia was induced with propofol mixed with ketamine hydrochloride. Horses were positioned in dorsal recumbency. Anesthesia was maintained with isoflurane in oxygen and a continuous rate infusion of butorphanol tartrate. One hour after anesthesia was induced, the blood sample protocol was repeated. Plasma ACTH concentrations were quantified by use of a commercially available sandwich assay. Generalized estimating equations that controlled for horse and an expressly automated deconvolution algorithm were used to determine effects of anesthesia on plasma ACTH concentrations and pulsatility, respectively. RESULTS Anesthesia significantly reduced the plasma ACTH concentration in blood samples collected from the cavernous sinus. CONCLUSIONS AND CLINICAL RELEVANCE Mean plasma ACTH concentrations in samples collected from the cavernous sinus of anesthetized horses were reduced. Determining the success of partial ablation of the pituitary gland in situ for treatment of pituitary pars intermedia dysfunction may require that effects of anesthesia be included in interpretation of plasma ACTH concentrations in cavernous sinus blood.

    OBJECT To detail the extent of resection and complications with endonasal endoscopic surgery for pituitary tumors invading the cavernous sinus (CS) using a moderately aggressive approach to maximize extent of resection through the medial cavernous sinus wall while minimizing the risk of cranial neuropathy and blood loss. Tumor in the medical cavernous sinus was aggressively pursued while tumor in the lateral cavernous sinus was debulked in preparation for radiosurgery. METHODS A prospective surgical database of consecutive endonasal pituitary surgeries with verified CS invasion on intraoperative visual inspection was reviewed. The extent of resection as a whole and within the CS was assessed by an independent neuroradiologist using pre- and post-operative Knosp-Steiner (KS) categorization and volumetrics of the respective magnetic resonance images. The extent of resection and clinical outcomes were compared for medial (KS1-2) and lateral (KS3-4) lesions. RESULTS Thirty-six consecutive patients with pituitary adenomas involving the CS who had surgery via an endonasal endoscopic approach were identified. The extent of resection was 84.6% for KS 1–2 and 66.6% for KS 3–4 (p=.04). Gross-total resection was 53.8% for KS 1–2 and 8.7% for KS 3–4 (p=.0006). Of six patients (16.8%) with pre-operative cranial neuropathies, all showed subjective improvement after surgery. Surgical complications included 2 transient post-operative cranial neuropathies (5.6%), 1 postoperative CSF leak (2.8%), 1 reoperation for mucocele (2.8%) and 1 infection (2.8%). CONCLUSIONS The endoscopic endonasal “medial-to-lateral” approach permits safe debulking of tumors in the medial and lateral CS. Although GTR rates are moderate, particularly in the lateral CS, the risk of permanent cranial neuropathy is extremely low with a high chance of improvement of pre-existing deficits. This approach can also facilitate targeting for post-operative radiosurgery. PMID:24527820

    The purpose of this study is to apply contrast-enhanced 3D fast-imaging employing steady-state acquisition (3D-FIESTA) imaging to the evaluation of cranial nerves (CN) in patients with cavernous sinus tumors. Contrast-enhanced 3D-FIESTA images were acquired from ten patients with cavernous sinus tumors with a 3-T unit. In all cases, the trigeminal nerve with tumor involvement was easily identified in the cavernous portions. Although oculomotor and abducens nerves were clearly visualized against the tumor area with intense contrast enhancement, they were hardly identifiable within the area lacking contrast enhancement. The trochlear nerve was visualized in part, but not delineated as a linear structure outside of the lesion. Contrast-enhanced 3D-FIESTA can be useful in the assessment of cranial nerves in and around the cavernous sinus with tumor involvement. (orig.)

    For the diagnosis and surgical treatment of diseases around the cavernous sinus (CS), radiologists should achieve complete mastery of the sectional anatomy of the CS, and neurosurgeons need to understand the stereoscopic orientation of the CS and circumjacent structures. However, despite the complicated structure of the CS, the current educational resources for its sectional and stereoscopic anatomy are insufficient. Another problem is that the definition of CS walls varies for each researcher. The purpose of this study is to redefine the walls of the CS and to provide related educational materials. Previous studies on the shape of the CS were analyzed. Sectioned images of a cadaver were prepared at 0.1-mm intervals to be made into three-dimensional (3D) models of the CS and neighboring structures. Based on other studies, the shape of the CS was redefined as a hexahedron, consisting of 6 walls, and was illustrated as a schematic figure. Scientific exactitude of the hexahedron was proven through matching the points with the actual structures on the sectioned images and 3D models that were made in this study. The combination of the hexahedron theory, the sectioned images, and the 3D models in this study will enhance the efficiency of studying CS anatomy. The educational resources of this study can be obtained free of charge by medical students, radiologists, and neurosurgeons requiring knowledge of CS anatomy. Copyright © 2015 Elsevier Inc.

    Full Text Available Abstract The purpose of this investigation was to enhance our understanding of cerebrospinal fluid (CSF absorption pathways. To achieve this, Microfil (a coloured silastic material was infused into the subarachnoid space (cisterna magna of sheep post mortem, and the relevant tissues examined macroscopically and microscopically. The Microfil was taken up by an extensive network of extracranial lymphatic vessels in the olfactory turbinates. In addition however, Microfil also passed consistently through the dura at the base of the brain. Microfil was noted in the spaces surrounding the venous network that comprises the cavernous sinus, in the adventitia of the internal carotid arteries and adjacent to the pituitary gland. Additionally, Microfil was observed within the endoneurial spaces of the trigeminal nerve and in lymphatic vessels emerging from the epineurium of the nerve. These results suggest several unconventional pathways by which CSF may be removed from the subarachnoid space. The movement of CSF to locations external to the cranium via these routes may lead to its absorption into veins and lymphatics outside of the skull. The physiological importance of these pathways requires further investigation.

    Full Text Available We report a case of a 90-year-old patient with intractable posterior epistaxis presenting as the only symptom of a nontraumatic low-flow carotid-cavernous sinus fistula. Purpose of this case report is to introduce low-flow carotid-cavernous sinus fistula in the differential diagnosis of intractable posterior epistaxis. We provide a literature review for the sequence of actions for the confrontation of posterior epistaxis. We also emphasize the significance of the radiological diagnostic and therapeutic procedures in the management of posterior epistaxis due to pathology of the cavernous sinus. The gold-standard diagnostic procedure of carotid-cavernous sinus fistula is digital subtraction angiography (DSA. DSA with coils is also the state-of-the-art therapy. By failure of DSA, neurosurgery or stereotactic radiosurgery (SRS may be used as alternatives. SRS may also be used as enhancement procedure of the DSA. Considering the prognosis of a successfully closed carotid-cavernous sinus fistula, recanalization occurs only in a minority of patients. Close follow-up is advised.

    OBJECTIVE Surgery within the cavernous sinus (CS) remains a controversial topic because of the delicate and complex anatomy. The risk also varies with tumor consistency. Softer tumors such as pituitary adenomas are more likely to be surgically treated, while firm tumors such as meningiomas are often treated with radiosurgery. However, a wide range of pathologies that can involve the CS are amenable to surgery. The authors describe and analyze their results using endonasal endoscopic "medial-to-lateral" approaches for nonadenomatous, nonmeningeal tumors, in relation to the degree of invasion within the CS. METHODS A prospectively acquired database of consecutive endoscopic approaches for tumors with verified intraoperative CS invasion was reviewed. Pituitary adenomas and meningiomas were excluded. Degree of invasion of the CS was classified using the Knosp-Steiner (KS) grading system as well as the percentage of cavernous carotid artery (CCA) encasement. Extent of resection of the entire tumor and of the CS component was assessed by independent neuroradiologists using volumetric measurements of the pre- and postoperative MRI studies. Demographic data and complications were noted. RESULTS Fifteen patients (mean age 51.1 years who received endoscopic surgery between 2007 and 2013 met the selection criteria. There were 11 malignant tumors, including chordoma, chondrosarcoma, hemangiopericytoma, lymphoma, and metastatic cancer, and 4 benign tumors, including 3 cavernous hemangiomas and 1 dermoid. All cases were discussed before treatment in a tumor board. Adjuvant treatment options included chemotherapy and radiotherapy. The mean pre- and postoperative tumor volumes were 12.74 ml and 3.86 ml. Gross-total resection (GTR; ie, resection greater than 95%) was the goal in 13 cases and was achieved in 6 patients (46%) while in addition 5 patients had a greater than 80% resection. Gross-total resection in the CS was accomplished in 55% of the tumors with KS Grades 1-2 and in

    To study the clinical and etiological profile of patients with cavernous sinus syndrome (CSS) and identify factors which could determine the etiology and influence the outcome of these patients. This prospective observational study included 73 consecutive patients satisfying the criteria of CSS (i.e. involvement of any 2 of the 3rd, 4th, 5th and 6th cranial nerves or any one of them with radiological evidence of cavernous sinus involvement). All these patients were subjected to detailed haematological, biochemical and radiological investigations and diagnosed and treated as per guidelines. The clinical and investigational data was recorded and analysed meticulously. A definitive etiological diagnosis of CSS could be achieved in 86% of patients. Tumours, fungal infections and Tolosa Hunt syndrome (THS) were most common causes. On univariate analysis, diabetes, severe vision loss (visual acuity of <3/60 in at least one eye), and presence of nasal discharge showed a significantly positive association with a fungal CSS. Evidence of paranasal sinusitis, bone erosion and ICA (internal carotid artery) involvement on Gadolinium enhanced MRI (magnetic resonance imaging) of brain were significantly associated with a fungal CSS (p=0.0001), whereas involvement of orbital apex had a negative association with a neoplastic etiology (p=0.014). On multiple logistic regression, orbital apex involvement on MRI was associated with diagnosis of THS (p=0.019, OR: 18.7; 95% CI: 1.6-217.4) while MRI evidence of paranasal sinusitis (p=0.014, OR: 45; 95% CI: 2.1-94.3) and bone erosion ((p=0.019, OR: 12.5; 95% CI: 1.5-103) correlated with diagnosis of fungal CSS. 65.2% of patients (fungal CSS- 70%) had a good prognosis at six months follow up. Most patients with CSS can be diagnosed accurately and managed properly with good outcomes. Copyright © 2017 Elsevier B.V. All rights reserved.

    The primary aim of our study was to determine whether an evidence-based rationale could categorize cavernous venous occlusive disease into mild, moderate and severe erectile dysfunction. A total of 863 patients underwent color duplex Doppler ultrasound from January 2010 to June 2013 performed by a single urologist. We identified a cohort of 75 patients (8.7%) with a diagnosis of cavernous venous occlusive disease based on a unilateral resistive index less than 0.9, and right and left peak systolic velocity 35 cm per second or less after visual sexual stimulation. At a median followup of 13 months patients were evaluated for treatment efficacy. A total of 75 patients with a median age of 60 years (range 19 to 83) and a mean body mass index of 26.3 kg/m(2) (range 19.0 to 39.3) satisfied the criteria of cavernous venous occlusive disease. When substratified into tertiles, resistive index cutoffs were obtained, including mild cavernous venous occlusive disease-81.6 to 94.0, moderate disease-72.6 to 81.5 and severe disease-59.5 to 72.5. Using these 3 groups the phosphodiesterase type 5-inhibitor failure rate (p = 0.017) and SHIM (Sexual Health Inventory for Men) score categories (1 to 10 vs 11 to 20, p = 0.030) were statistically significantly different for mild, moderate and severe cavernous venous occlusive disease. Treatment satisfaction was also statistically significantly different. Penile prosthetic placement was a more common outcome among patients with erectile dysfunction and more severe cavernous venous occlusive disease. Our retrospective analysis supports a correlation between the phosphodiesterase type 5 inhibitor failure rate, SHIM score and the rate of surgical intervention using resistive index values. Our data further suggest that an evidence-based classification of cavernous venous occlusive disease by color Doppler ultrasound is possible and can triage patients to penile prosthetic placement.

    This study aimed to investigate the application of 3-dimensional computed tomography angiography (3D-CTA) for defining cavernous sinus aneurysms and intradural aneurysms involving the internal carotid artery around the anterior clinoid process. Results from 42 patients with an aneurysm of the internal carotid artery around the anterior clinoid process who underwent 3D-CTA were reviewed and compared with those of observed clinical operations. Among the 42 patients, there was a total of 45 aneurysms of the internal carotid artery around the anterior clinoid process. After surgery, 33 of the 45 aneurysms were confirmed as intradural aneurysms, and the other 12 were confirmed as aneurysms in the cavernous sinus. 3D-CTA imaging of the medial sagittal plane showed that 31 out of 31 (100%) intradural aneurysms of the internal carotid artery were above the virtual line between the inferior border of the anterior clinoid process and the tuberculum sellae, and 12 out of 14 (86%) cavernous sinus aneurysms were below the virtual line (P cavernous sinus aneurysms from intradural aneurysms involving the internal carotid artery around the anterior clinoid process.

    The presence of a cortical venous reflux (CVR) in a carotid-cavernous fistula (CCF) is well described and is considered to be a criterion for urgent treatment. This reflux is often associated with direct/traumatic CCF and the high-flow of the fistula alone explains the reflux. For indirect CCF, the pathophysiology of a CVR is unclear. All patients treated endovascularly for an indirect CCF with a cortical venous reflux between 2003 and 2015 were included. We retrospectively analysed data focusing on whether venous outflows of the cavernous sinus would opacify or not with the local injection of contrast, in order to locate those that could explain the venous reflux. Twenty consecutive patients (male/female ratio, 2/3) were included in this series with a mean age of 63 years. All patients presented ocular signs and no patients showed any neurological sign secondary to the CVR. We distinguished four patterns of CVR: in the superficial middle cerebral vein (75%), in the uncal vein (15%), in the superior petrosal vein (5%) and in the inferior petrosal vein (5%). Seventy percent of the cases presented a lack of opacification in more than three venous outflows of the CS involved. Each patient received an endovascular therapy by venous approach with a success rate of 76.9% per embolisation session. Two patients (10%) presented a permanent ocular paresis and two others a transient deficit. CVR is directly correlated with the thrombosis of multiple venous outflows of the CS. The "non-opacification" of at least three of the CS venous outflows is necessary for the development of CVR. Such thrombosis may be explained by the combination of haemodynamic and inflammatory changes of the venous wall.

    Exposure of the cavernous sinus or anterior parahippocampus often involves a wide exposure of the temporal lobe and mobilization of the temporalis muscle associated with temporal lobe retraction. The authors present a cadaveric study to illustrate the feasibility, advantages and landmarks necessary to perform a trans-zygomatic middle fossa approach to lesions around the cavernous sinus and anterior parahippocampus. The authors performed bilateral trans-zygomatic middle fossae exposures to reach the cavernous sinus and parahippocampus in five cadavers (10 sides). We assessed the morbidity associated with this procedure and compared the indications, advantages, and disadvantages of this method versus more extensive skull base approaches. A vertical linear incision along the middle portion of the zygomatic arch was extended one finger breadth inferior to the inferior edge of the zygomatic arch. Careful dissection inferior to the arch allowed preservation of facial nerve branches. A zygomatic osteotomy was followed via a linear incision through the temporalis muscle and exposure of the middle cranial fossa floor. A craniotomy along the inferolateral temporal bone and middle fossa floor allowed extradural dissection along the middle fossa floor and exposure of the cavernous sinus including all three divisions of the trigeminal nerve. Intradural inspection demonstrated adequate exposure of the parahippocampus. Exposure of the latter required minimal or no retraction of the temporal lobe. The trans-zygomatic middle fossa approach is a simplified skull base exposure using a linear incision, which may avoid the invasivity of more extensive skull base approaches while providing an adequate corridor for resection of cavernous sinus and parahippocampus lesions. The advantages of this approach include its efficiency, ease, minimalism, preservation of the temporalis muscle, and minimal retraction of the temporal lobe.

    Cavernous sinus (CS) dural arteriovenous fistulas (DAVFs) rarely cause venous infarction (VI) and/or intracranial hemorrhage (ICH) despite the presence of cortical venous drainage (CVD). The present study investigated the characteristics of CS DAVFs manifesting as VI/ICH. Fifty-four patients treated for CS DAVFs were retrospectively studied. Six patients presented with VI/ICH. Two of the three patients presenting with ICH had CVD only to the superficial sylvian vein (SSV) or the deep sylvian vein (DSV). Three patients presenting with VI had multiple drainages, and angiography of these patients showed a varix on the SSV, drainage into the DSV with agenesis of the second and third segment of basal vein of Rosenthal, and thrombosis of the distal petrosal vein. CS DAVF with CVD only carries higher risk of VI/ICH than multiple drainages. Many CS DAVFs presenting with VI, especially those with drainage into the petrosal vein, have multiple drainages in the early stage. Thrombosis of the inferior and superior petrosal sinuses and superior orbital vein gradually increases pressure of the CVD, and then, VI may occur. In contrast, CS DAVFs with CVD only from the beginning, common in the patients with drainage into the SSVs and DSVs, are likely to cause ICH. Angiographic risk factors causing VI/ICH are CVD only, varix formation, agenesis of the second and third segment of basal vein of Rosenthal, and thrombosis of the superior orbital vein, lateral half of the superior petrosal sinus, and distal CVD.

    To evaluate the anatomy of cranial nerves running in and around the cavernous sinus, we employed three-dimensional reversed fast imaging with steady-state precession (FISP) with diffusion weighted imaging (3D PSIF-DWI) on 3-T magnetic resonance (MR) system. After determining the proper parameters to obtain sufficient resolution of 3D PSIF-DWI, we collected imaging data of 20-side cavernous regions in 10 normal subjects. 3D PSIF-DWI provided high contrast between the cranial nerves and other soft tissues, fluid, and blood in all subjects. We also created volume-rendered images of 3D PSIF-DWI and anatomically evaluated the reliability of visualizing optic, oculomotor, trochlear, trigeminal, and abducens nerves on 3D PSIF-DWI. All 20 sets of cranial nerves were visualized and 12 trochlear nerves and 6 abducens nerves were partially identified. We also presented preliminary clinical experiences in two cases with pituitary adenomas. The anatomical relationship between the tumor and cranial nerves running in and around the cavernous sinus could be three-dimensionally comprehended by 3D PSIF-DWI and the volume-rendered images. In conclusion, 3D PSIF-DWI has great potential to provide high resolution "cranial nerve imaging", which visualizes the whole length of the cranial nerves including the parts in the blood flow as in the cavernous sinus region.

    The pathogenic association between cavernous dural arteriovenous fistula (CDAVF) and moyamoya disease remains unclear. This unusual case is the first report of a progression of unilateral moyamoya disease resulting in the spontaneous occlusion of ipsilateral CDAVF. A 52-year-old woman presented with two-week spontaneous exophthalmos, chemosis and tinnitus, and cerebral angiography showed a right CDAVF coexisting with ipsilateral moyamoya disease. Transvenous approaches through the inferior petrosal sinus and facial vein were attempted but failed. However, a progression of the moyamoya disease and disappearance of the CDAVF were observed on one month follow-up angiogram in accordance with the resolution of clinical symptoms. This extremely rare coincidental presentation may have deeper pathogenic implications. This case report may give a clue to the underlying mechanism of the progression of moyamoya disease and occlusion of the CDAVF. © The Author(s) 2016.

    Extradural anterior clinoidectomy via the trans-superior orbital fissure (SOF) approach can provide extensive exposure of the anterior clinoid process and safe drilling under direct view. This technique requires peeling of the dura propria of the temporal lobe from the lateral wall of the SOF. Therefore, cadaveric dissection is mandatory to acquire surgical technique. However, chances for cadaveric dissection are limited. We propose modification of our three-dimensional (3-D) skull base model made from surgically dissectable artificial bone with artificial cavernous sinus including multiple membranous layers and neurovascular structures to simulate extradural anterior clinoidectomy via the trans-SOF approach. The 3-D skull base model precisely reproduced the dura propria of the temporal lobe, periosteal bridge, and inner reticular layer in the cavernous sinus and SOF using silicone and varnish. The cranial nerves and blood vessels were made from rubber fibers and vinyl tube. Simulation of extradural anterior clinoidectomy via the trans-SOF approach could be performed on the model using a high-speed drill under the operating microscope. The steps of reconstruction of the skull base model and dissection promote clear understanding of the 3-D anatomy and techniques of extradural anterior clinoidectomy via the trans-SOF approach.

    The objective of the study was to determine whether the local permeability of luteinizing hormone-releasing hormone (LHRH) from the venous blood of the perihypophyseal cavernous sinus into the arterial blood of the carotid rete, supplying the brain and hypophysis in gilts, depends on the day of the estrous cycle, as well as to determine whether this transfer exists when LH concentration in the blood is reduced (the experimental short-loop negative feedback for LH secretion after estradiol injection in ovariectomized gilts). Experiments were conducted on isolated gilt heads with necks, on chosen days of the estrous cycle (n = 40), and on previously ovariectomized gilts treated with estradiol benzoate (EB) (n = 5) or corn oil (n = 3). After exsanguination, the gilt heads with necks were disarticulated and about 30-45 min later were supplied with autologous, oxygenated, and heated blood at a stable blood flow and pressure through the left carotid artery for 30 min. 125I-LHRH was infused into both cavernous sinuses through the cannulated angularis oculi veins for 5 min. After 125I-LHRH infusion, radiolabeled LHRH was found (P gilts), on Days 12-14 (seven gilts) of the estrous cycle, and in five ovariectomized gilts during negative feedback for LH surge (40 hr after EB). No significant radioactivity of 125I-LHRH was found in the arterial blood on Days 3-5 (n = 6), 9-11 (n = 4), and 15-21 (n = 17) of the estrous cycle. A very low level of radioactivity was found in the ovariectomized control group after the injection of corn oil (n = 3). These results provide evidence for the permeability of LHRH from the venous to the arterial blood and its retrograde transport with the arterial blood to the hypophysis and brain, after the ovulation period (Days 1-2) and on Days 12-14 of the estrous cycle. This suggests that a close relationship exists between the day of the estrous cycle and LHRH permeability from the venous to the arterial blood in the perihypophyseal cavernous sinus

    Evaluation of outcome of pilonidal sinus excision using a radiofrequency device and comparing its results with excision and open granulation procedure. Patients with sacro-coccygeal pilonidal sinus disease (n=44) were randomly assigned to undergo either a wide excision and healing by open granulation procedure [WEG] (n=23) or a radiofrequency sinus excision [RSE] (n=21). An Ellman radiofrequency generator was used for RSE. Intra- and postoperative events and outcome data were evaluated and analyzed by Student's unpaired t test and chi(2) test. The significant differences in the two groups WEG and RSE were as follows: mean hospital stay (47 vs. 10 h, p< 0.05), period off work (29 vs. 8 days, p< 0.05), mean analgesic requirement (39 vs. 15 tablets, p< 0.05), time for complete wound healing (84 vs. 49 days, p< 0.05). At the mean follow-up of 30 months, 2 patients from the wide excision and open granulation group and one patient from the radiofrequency sinus excision group developed recurrence. These findings suggest that sinus excision with radiofrequency is a simple and swift procedure. It needs a short hospital stay and is associated with less postoperative pain and early resumption to work. As compared to excision and healing by granulation technique, the radiofrequency sinus excision procedure achieves faster wound healing and a better outcome. Copyright (c) 2005 S. Karger AG, Basel.

Bilateral presentation is only seen in bilateral fistulas, usually associated with indirect (dural) carotid cavernous fistulas. Direct carotid cavernous fistulas are an abnormal communication between the internal carotid artery and the cavernous sinus. They typically begin with a traumatic disruption in the artery wall into the cavernous sinus, presenting with a classic triad of unilateral pulsatile exophthalmos, cranial bruit and episcleral venous engorgement. We report the case of a 38-year-old male with traumatic right carotid cavernous sinus fistula and bilateral ocular presentation successfully treated by interventional neuroradiology.

    The aim of this study was to test the hypothesis that the superficial middle cerebral vein (SMCV) is frequently absent or fails to connect with the cavernous sinus (CS) in the presence of brain arteriovenous malformations (AVMs), a frequently reported argument for the congenital origin of brain AVMs. The SMCV was retrospectively compared between patients with a brain AVM and a control group. The presence or absence of the SMCV, its direct or indirect connection to the CS and its termination in a laterocavernous sinus (LCS), paracavernous sinus (PCS), or directly in the CS was studied on digital subtraction angiography. One hundred twenty-five left or right side carotid angiograms from 70 patients with a brain AVM were compared to 125 angiograms from 74 controls. The SMCV was present in 88 (70.4 %) cases in the brain AVM group and 96 (76.8 %) cases in controls (p = 0.25). The SMCV was connected directly or indirectly to the CS in 65 (52 %) cases in the brain AVM group and 65 (52 %) cases in controls (p = 1). When comparing the subgroup of carotid angiograms ipsilateral to a supratentorial AVM, no statistically significant difference was found with controls. In three of six cases in which a SMCV drained an AVM, the vein terminated directly or indirectly in the CS. No difference of SMCV presence and direct or indirect connection to the CS was found between patients with AVM and a control group. SMCV anatomy does not support the congenital origin of brain AVMs.

    Full Text Available We describe the case of an 83-year-old woman with left-sided ophthalmoplegia. She had no family history of connective tissue disease. The computed tomography study found a dilated left cavernous sinus. The conventional cerebral panangiography confirmed the diagnosis - a direct carotid-cavernous fistula (CCF, with no evidence of ruptured aneurysm. The woman underwent endovascular treatment with coiling of the cavernous sinus in combination with application of the Onyx embolic agent in the fistula. During the first 48 hours after the embolization the local pain, exophthalmos and conjunctival injection of the left eye were significantly ameliorated. The pulsatile tinnitus on the left disappeared and the ptosis of the left eyelid partially recovered. Selective angiography is the best method for the diagnosis and classification of CCF. Currently, treatment is possible with low mortality and morbidity rates. The endovascular intervention is able to completely occlude the fistula and maintain adequate blood fl ow through the carotid artery.

    In skull base tumors involving the cavernous sinus, indications for aggressive resection are sparse and must be carefully examined because of their invasiveness. With careful evaluation, techniques including internal carotid artery sacrifice with or without extracranial-intracranial bypass may still be an option in some cases. Moreover, previous surgery with the sacrifice of potential donor vessels requires adjusting the revascularization strategy. We describe an occipital artery-middle cerebral artery bypass before skull base tumor resection. A 47-year-old woman with a recurrent cavernous sinus meningioma was referred to our department. Because of tumor recurrence after radiotherapy and its rapid progression, radical resection, including part of the cavernous sinus, was planned. A balloon test occlusion was performed and showed good tolerance. An endovascular internal carotid artery occlusion was performed. The patient eventually experienced motor deficits and aphasia after surgery. Therefore, bypass surgery using an occipital artery-middle cerebral artery anastomosis was performed. The patient showed no exacerbation of symptoms after bypass surgery and subsequently underwent tumor resection. The reliability of balloon test occlusion in the management of giant aneurysms may not be similarly applicable to skull base tumors. If hypoperfusion symptoms occur after occlusion of the internal carotid artery, a surgical revascularization procedure should be considered because of the risk of ischemic stroke following tumor resection. For patients whose superficial temporal artery is not available, the occipital artery can be a valuable alternative donor for low-flow bypass. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available A carotid-cavernous fistula (CCF is an abnormal communication between the cavernous sinus and the carotid arterial system. A CCF is divided into two categories, direct and indirect. Direct fistulas usually account for 70 to 90% of all CCF. Spontaneous, low-flow fistulas are usually associated with atherosclerosis, hypertension and collagen vascular disease or may develop in females during peripartum period. The elderly age group, especially women are at increased risk. We report three cases of spontaneous CCF presenting with ocular manifestations and hypertension, without any collagen vascular disease. One case was a direct variety and the other two were of indirect variety.

    We report on a patient with 2 Mendelian diseases-symptomatic multiple familial cerebral cavernous malformations (FCCMs) and Wilson disease. Genetic analysis revealed single nucleotide polymorphisms in genes CCM2 and CCM3, associated with cavernous malformations, and homozygote mutation in the ATP7B gene, responsible for Wilson disease. FCCMs were symptomatic in 3 generations. The patient also had multiple lipomatosis, which is suggested to be a familial syndrome. In recent years there has been an increasing amount of publications linking FCCMs with other pathology, predominantly with extracranial and intracranial mesenchymal anomalies. The present study is the description of an unusual association between 2 independent hereditary diseases of confirmed genetic origin-a combination that has not been described previously.

    Arteriovenous fistulae of the cavernous sinus are rare and difficult to diagnose. They are classified into dural cavernous sinus fistulae or direct carotid-cavernous fistulae. Despite the similarity of symptoms between both types, a precise diagnosis is essential since the treatment is specific for each type of fistula. Imaging findings are remarkably similar in both dural cavernous sinus fistulae and carotid-cavernous fistulae, but it is possible to differentiate one type from the other. Amongst the available imaging methods (Doppler ultrasonography, computed tomography, magnetic resonance imaging and digital subtraction angiography), angiography is considered the gold standard for the diagnosis and classification of cavernous sinus arteriovenous fistulae. The present essay is aimed at didactically presenting the classification and imaging findings of cavernous sinus arteriovenous fistulae. PMID:25741093

    So-called direct carotid-cavernous fistulas (CCFs) are commonly treated by detachable balloons or coils to occlude the shunt while sparing the carotid artery. Liquid embolic agents have been rarely used, and in particular, to the authors' knowledge, the use of Onyx as the sole agent has never been reported in an indexed publication. The authors describe a case series of 5 patients with posttraumatic CCF in whom embolization with Onyx was prospectively used as the sole strategy of management. Complete occlusion was obtained at the end of the procedure in 4 cases, and the lesion in the remaining patient subsequently occluded at the 6-month follow-up evaluation. As endovascular techniques for treatment of direct CCFs continue to evolve, this novel approach with Onyx as the sole embolic material seems promising in treating these lesions.

    Cavernous sinus (CS) dural arteriovenous fistula (DAVF) rarely causes intracranial hemorrhage. The authors describe a case of CS DAVF presenting with intracranial hemorrhage, focusing on the findings in digital subtraction angiography (DSA) performed before and after the onset. An 80-year-old woman, diagnosed as Borden type 3 CS DAVF on DSA 2 years before, presented with subarachnoid hemorrhage and right temporal subcortical hemorrhage. DSA findings after the onset showed that the right superficial middle cerebral vein, the sole drainage of the DAVF, had various changes including stenosis on the proximal portion, venous pouch formation, and occlusion of the distal portion compared with those 2 years before the onset. The occlusion was observed near the point where drainage of DAVF joined normal brain venous drainage, suggesting that the competition between the drainages caused impaired venous drainage, stagnation, and subsequent thrombotic occlusion. The CS DAVF was treated with evacuation of the intracerebral hematoma and surgical interruption of the right superficial middle cerebral vein at the dural origin from the CS. This report showed the development of thrombotic occlusion of a distal draining cortical vein as one of risk factors for CS DAVFs to cause intracranial hemorrhage on repeated DSAs.

    Acute paranasal sinus infection in children is often diagnosed clinically without the need for radiographic confirmation. Most cases have a favorable outcome following appropriate antibiotic therapy. A small percentage of cases where symptoms and signs are persistent or severe will require emergent imaging to rule out complications related to local spread of disease intraorbitally or intracranially. A strong index of suspicion is required in such cases, and cross-sectional imaging evaluation with CT and MRI should include axial and coronal images of the paranasal sinuses and, where appropriate, the orbits and brain (with attention to the cavernous sinus). There is no role for plain radiography in the evaluation of the complications of acute sinusitis in the pediatric patient. (orig.)

    The bovine paranasal sinuses are a group of complex cavernous air-filled spaces, lined by respiratory epithelium, the exact function of which is unclear. While lesions affecting these sinuses are occasionally reported in cattle, their microbial flora has not been defined. Furthermore, given that the various bacterial and viral pathogens causing bovine respiratory disease (BRD) persist within herds, we speculated that the paranasal sinuses may serve as a refuge for such infectious agents. The paranasal sinuses of clinically normal cattle (n = 99) and of cattle submitted for post-mortem examination (PME: n = 34) were examined by microbial culture, PCR and serology to include bacterial and viral pathogens typically associated with BRD: Mycoplasma bovis, Histophilus somni, Mannheimia haemolytica and Pasteurella multocida, bovine respiratory syncytial virus (BRSV) and bovine parainfluenza-3 virus (BPIV-3). Overall, the paranasal sinuses were either predominantly sterile or did not contain detectable microbes (83.5%: 94.9% of clinically normal and 50.0% of cattle submitted for PME). Bacteria, including BRD causing pathogens, were identified in relatively small numbers of cattle (bovine sinus as it does in humans.

    Erectile dysfunction is often a harbinger of cardiovascular disease. We sought to gain mechanistic insight at the cellular and molecular levels into why erectile dysfunction precedes the clinical consequences of cardiovascular disease. Diabetes was induced by intraperitoneal streptozotocin injection in 8-week-old C57BL/6J mice. At 8 weeks after diabetes induction, we determined the expression of endothelial cell-cell junction proteins and vascular endothelial permeability in the penis, heart and hind limb by systemic injection of various vascular space markers (350 Da to 2,000 kDa) or by immunohistochemical staining with antibody to oxidized low density lipoprotein. We also investigated the effect of recombinant Ang1 protein on cavernous endothelial permeability. Alterations in the integrity of the endothelial cell-cell junction, including a decrease in endothelial cell-cell junction proteins and an increase in vascular permeability to fluorescent tracers or oxidized low density lipoprotein, were prominent in the cavernous tissue of diabetic mice. In contrast, no significant changes in endothelial cell-cell junction proteins or vascular permeability were noted in heart or hind limb tissue according to the diabetic condition. Intracavernous injection of Ang1 protein, an anti-permeability factor, significantly decreased cavernous endothelial permeability to oxidized low density lipoprotein by restoring endothelial cell-cell junction proteins in diabetic mice. The incompetent cavernous endothelial cell-cell junction in the diabetic condition provides an important clue to why erectile dysfunction is highly prevalent and often precedes other systemic vascular diseases.

    2016-11-01

    Full Text Available Mutations in the genes KRIT1, CCM2, and PDCD10 are known to result in the formation of cerebral cavernous malformations (CCMs. CCMs are intracranial lesions comprised of aberrantly enlarged cavernous endothelial channels that can result in cerebral hemorrhage, seizures, and neurologic deficits. Although these genes have been known to be associated with CCMs since the 1990s, numerous discoveries have been made that better elucidate how they and their subsequent protein products are involved in CCM pathogenesis. Since our last review of the molecular genetics of CCM pathogenesis in 2012, breakthroughs include a more thorough understanding of the protein structures of the gene products, involvement with integrin proteins and MEKK3 signaling pathways, the importance of CCM2-PDCD10 interactions, and others. In this review, we highlight the advances that further our understanding of the gene to protein to disease relationships of CCMs.

    The classic symptoms and signs of carotid cavernous sinus fistula or cavernous sinus dural arteriovenous fistula (AVF) consist of eye redness, exophthalmos, and gaze abnormality. The angiography findings typically consist of arteriovenous shunt at cavernous sinus with ophthalmic venous drainage with or without cortical venous reflux. In rare circumstances, the shunts are localized outside the cavernous sinus, but mimic symptoms and radiography of the cavernous shunt. We would like to present the other locations of the arteriovenous shunt, which mimic the clinical presentation of carotid cavernous fistulae, and analyze venous drainages. We retrospectively examined the records of 350 patients who were given provisional diagnoses of carotid cavernous sinus fistulae or cavernous sinus dural AVF in the division of Interventional Neuroradiology, Ramathibodi Hospital, Bangkok between 2008 and 2014. Any patient with cavernous arteriovenous shunt was excluded. Of those 350 patients, 10 patients (2.85%) were identified as having noncavernous sinus AVF. The angiographic diagnoses consisted of three anterior condylar (hypoglossal) dural AVF, two traumatic middle meningeal AVF, one lesser sphenoid wing dural AVF, one vertebro-vertebral fistula (VVF), one intraorbital AVF, one direct dural artery to cortical vein dural AVF, and one transverse-sigmoid dural AVF. Six cases (60%) were found to have venous efferent obstruction. Arteriovenous shunts mimicking the cavernous AVF are rare, with a prevalence of only 2.85% in this series. The clinical presentation mainly depends on venous outflow. The venous outlet of the arteriovenous shunts is influenced by venous afferent-efferent patterns according to the venous anatomy of the central nervous system and the skull base, as well as by architectural disturbance, specifically, obstruction of the venous outflow.

    Diseases of the pediatric nose and nasal sinuses as well as neighboring anatomical structures encompass a variety of pathologies, especially of inflammatory nature. Congenital disease, such as malformations and structural deviations of the nasal septum, as well as systemic metabolic pathologies affecting the nose and sinuses, rarely require medical therapy from an Otolaryngologist. The immunological function of the mucosa and genetic factors play a role in the development of disease in the pediatric upper airway tract, especially due to the constantly changing anatomy in this growth phase. Disease description of the nose and nasal sinuses due to mid-facial growth must also take developmental age differences (infant, toddler, preschool, and school age) into account. Epidemiological examinations and evidence based studies are often lacking in the pediatric population. The wide range of inflammatory diseases of the nose and paranasal sinuses, such as the acute and chronic rhinosinusitis, the allergic rhinitis, and adenoid disease, play a role in the susceptibility of a child to infection. The susceptibility to infection depends on the pediatric age structure (infant, young child) and has yet to be well defined. The acute rhinosinusitis in children develops after a viral infection of the upper airways, also referred to as the "common cold" in the literature. It usually spontaneously heals within ten days without any medical therapy. Antibiotic therapy is prudent in complicated episodes of ARS. The antibiotic therapy is reserved for children with complications or associated disease, such as bronchial asthma and/or chronic bronchitis. A chronic rhinosinusitis is defined as the inflammatory change in the nasal mucosa and nasal sinus mucosa, in which the corresponding symptoms persist for over 12 weeks. The indication for CT-imaging of the nasal sinuses is reserved for cases of chronic rhinosinusitis that have been successfully treated with medication. A staged therapeutic

    Corpus cavernosum electromyography has been widely done to evaluate autonomic dysfunction in patients with erectile dysfunction. We assessed the value of corpus cavernosum electromyography, evoked cavernous activity and penile sympathetic skin responses for their accuracy in determining autonomic involvement in cases of erectile dysfunction. We evaluated 75 men with erectile dysfunction by corpus cavernosum electromyography, evoked cavernous activity and penile sympathetic skin response tests at our neurourology laboratory. The etiology of dysfunction was vascular, neurogenic, psychogenic or mixed based on a detailed medical and sexual history, physical examination, electrophysiological and laboratory studies, penile color Doppler ultrasonography, and cavernosography and/or cavernosometry. Autonomic involvement was clinically assessed by systemic findings, such as orthostatic hypotension, impaired gastrointestinal motility, sinus dysrhythmia and secretomotor changes. A concentric electromyography needle placed in the right cavernous body was used to record corpus cavernosum electromyography and evoked cavernous activity. The right median nerve was stimulated electrically with 13 to 16 mA. to determine evoked cavernous activity and the penile sympathetic skin response. The latter response was recorded with silver disc electrodes placed on the left cavernous body. All tests were performed using an electromyography/evoked potential machine. We determined the relationships among corpus cavernosum electromyography, evoked cavernous activity and penile sympathetic skin response tests in respect to etiological factors. The 56 patients with normal corpus cavernosum electromyography activity had also evoked cavernous activity and a penile sympathetic skin response except for 1 with no penile sympathetic skin response but evoked cavernous activity. None of these patients had autonomic neuropathy. Of the 19 patients without corpus cavernosum electromyography activity 11 had

While serology indicated widespread exposure of both clinically normal and cattle submitted for PME to BPIV-3 and BRSV (seroprevalences of 91.6% and 84.7%, respectively, PCR identified BPIV-3 in only one animal. To further explore these findings we investigated the potential role of the antimicrobial molecule nitric oxide (NO within paranasal sinus epithelium using immunohistochemistry. Expression of the enzyme responsible for NO synthesis, inducible nitric oxide synthase (iNOS, was detected to varying degrees in 76.5% of a sub-sample of animals suggesting production of this compound plays a similar protective role in the bovine sinus as it does in humans.

    To investigate the risk factors for pilonidal sinus in teenagers. Between January 2013 and September 2015, 55 teenage patients who underwent surgery due to pilonidal sinus disease (PSD) in the Department of Pediatric Surgery, Sakarya University Teaching and Research Hospital were included in this study. Age, gender, body mass index (BMI), number of baths taken per week, time spent sitting per day, family history, and skin color were examined as risk factors. The control group comprised of healthy teenagers without pilonidal sinus disease. Out of the total 42 teenagers, 23 (54.8 %) were girls and 19 (45.2 %) were boys. Patients were classified as obese, overweight, or normal according to their BMI (14.3 %, 31 %, and 54.8 %, respectively). The number of baths taken per week in the PSD group was lower than that in the control group [odds ratio (OR): 3.690; p = 0.004]. The family history of PSD was significantly higher in teenagers with PSD, compared to the control group (OR: 8.652; p = 0.005). No differences were detected between the PSD and control groups with respect to sitting for ≥ 6 h per day (OR: 3.212; p = 0.028). Skin color was not found to be affected by PSD in teenagers (OR: 1.294; p = 0.392). Heredity and the number of baths taken per week were found to significantly affect the incidence of PSD, whereas other variables (gender, age, BMI, skin color, and time spent sitting per day) did not exhibit any significant influence on the rate of incidence.

    Full Text Available To investigate the prognostic value of cavernoussinus invasion (CSI in patients with nasopharyngeal carcinoma (NPC treated with intensity-modulated radiotherapy (IMRT.Retrospective review of data from 1,087 patients with biopsy-proven, non-metastatic NPC. All patients were diagnosed using magnetic resonance imaging (MRI scans and received IMRT as the primary treatment.The incidence of cavernoussinus invasion in this cohort was 12.1%. In univariate analysis, 5-year overall survival (OS (70.6% vs. 88.5%, P < 0.001 and distant metastasis-free survival (DMFS (71.4% vs. 87.7%, P < 0.001, but not locoregional relapse-free survival (LRFS (93.9% vs. 93.7%, P = 0.341, were significantly different between patients with and without cavernoussinus invasion. In the T4 subgroup, the 5-year OS, DMFS, and LRFS of patients with and without cavernoussinus extension were 70.6% vs. 81.9% (P = 0.011, 71.4% vs. 84.1% (P = 0.011, and 91.2% vs. 89.7% (P = 0.501, respectively. In multivariate analysis, cavernoussinus invasion was an independent prognostic factor for poorer OS (HR = 1.782; P = 0.013 and DMFS (HR = 1.771; P = 0.016, but not LRFS (HR = 0.632; P = 0.294. In patients with lymph node metastasis, the DMFS rates of patients with and without cavernoussinus invasion were significantly different (P < 0.001. Preliminaryanalysis indicated that neoadjuvant chemotherapy led to better DMFS and OS in patients with cavernoussinus invasion than concurrent chemotherapy or radiotherapy alone; however, the differences were not significant.In the IMRT era, cavernoussinus invasion remains a prognostic factor for poor DMFS and OS in NPC, even in patients with T4 disease.

    To evaluate the relative diagnostic accuracy of panoramic radiography and Water's projection in maxillary sinus inflammatory diseases by comparing the radiodensities of the images with those of CT. Panoramic radiographs, Waters' projection, and CT images from 55 subjects (110 sinuses) were included in this retrospective study. The radiodensity of each maxillary sinus in panoramic radiography was recorded separately as upper and lower divided horizontally by hard palate. In Waters' projection, the overall sinus radiodensity was recorded. The CT images were considered as gold standard. In panoramic radiography, 83 sinuses had same upper and lower radiodensity and 72 of these were consistent with those of CT, 26 sinuses had different upper and lower radiodensity and 15 of these, upper radiodensity was consistent with CT, the remaining 11, lower radiodensity was consistent with CT. One sinus had upper radiolucency with lower radiopacity and both were consistent with those of CT. Altogether 73 (66.4%) among 110 sinuses in panoramic radiography showed full agreement with CT, 26 (23.6%) showed partial agreement with CT. 9 sinuses had no lower image under the hard palate in panoramic radiography due to the smaller size of sinus. In Waters' projection, the radiodensity of 105 sinuses (95.5%) were consistent with that of CT. The panoramic radiography showed 90.0% of the sinus conditions fully or partially which may appear less accurate than that of Water's view (95.5%) but with more detailed information of the inferior part of sinuses.

    It has been reported that periodontitis is associated with Alzheimer's disease. However, the association between paranasal sinusitis and Alzheimer's disease has not been studied, although olfactory dysfunction frequently precedes the progress of dementia or Alzheimer's disease. We studied 783 patients (283 men, 500 women; mean age 77.0 ± 7.9 years) who visited the Center for Comprehensive Care and Research on Memory Disorders, National Center for Geriatrics and Gerontology, and 2139 control subjects who participated in a population-based study conducted by the National Institute for Longevity Sciences - Longitudinal Study of Aging (NILS-LSA) in Japan. Sinusitis was evaluated using magnetic resonance imaging (MRI) according to the Lund-Mackay scoring system. A sinusitis score of ≥ 4 was classified as positive and a score of ≤ 3 was classified as negative. The prevalence of positive sinusitis was 6.3% in patients with a mini-mental state examination (MMSE) score of sinusitis was7.2% in the control group. The prevalence of sinusitis was not significantly different between normal controls and patients with dementia or Alzheimer's disease after adjustments for age and sex. The rate of positive sinusitis was higher in male than in female subjects in both groups. The prevalence of sinusitis in patients with Alzheimer's disease or dementia was not higher than in the general population.

    Full Text Available and lsquo;Pilonidal sinus' disease, which is most commonly seen in reproductive populations, such as young adults - mostly in males who are in their twenties - is actually a controversial disease in that there is no consensus on its many facets. It is sometimes seen as an infected abscess draining from an opening or a lesion extending to the perineum. It may also present as a draining fistula opening to skin. In terms of etiological factors, various theories (main theories being congenital and acquired have been established since it was first described, no universal understanding achieved. A long and significant post-operative care period with different lengths of recovery depending on the type of operation are quite prevalent with regards to recurrence and complication status. In order to prevent recurrence and improve the quality of life, etiological and predisposing factors as well as clinical features of sacrococcygeal pilonidal disease should be well known, a detailed differential diagnosis should be made, and a suitable and timely intervention should be performed. It was aimed here to explain the etiological factors, pathogenesis and clinical features of the disease that may present with various clinical symptoms. [Arch Clin Exp Surg 2016; 5(4.000: 228-232

    Purpose The phenotypic manifestations of cerebral cavernous malformation (CCM) disease caused by rare PDCD10 mutations have not been systematically examined, and a mechanistic link to Rho kinase (ROCK) mediated hyperpermeability, a potential therapeutic target, has not been established. Methods We analyze PDCD10-siRNA treated endothelial cells for stress fibers, ROCK activity and permeability. ROCK activity is assessed in CCM lesions. Brain permeability and CCM lesion burden is quantified, and clinical manifestations are assessed in prospectively enrolled subjects with PDCD10 mutations. Results We determine that PDCD10 protein suppresses endothelial stress fibers, ROCK activity and permeability in vitro. Pdcd10 heterozygous mice have greater lesion burden than other Ccm genotypes. We demonstrate robust ROCK activity in murine and human CCM vasculature, and increased brain vascular permeability in humans with PDCD10 mutation. Clinical phenotype is exceptionally aggressive compared to the more common KRIT1 and CCM2 familial and sporadic CCM, with greater lesion burden and more frequent hemorrhages earlier in life. We first report other phenotypic features including scoliosis, cognitive disability and skin lesions, unrelated to lesion burden or bleeding. Conclusion These findings define a unique CCM disease with exceptional aggressiveness, and they inform preclinical therapeutic testing, clinical counseling and the design of trials. PMID:25122144

    Cavernous sinus thrombophlebitis (CST) is a rare and life-threatening disease without prompt diagnosis and treatment. Two cases of fulminant superior ophthalmic vein (SOV) and CST caused by maxillary periodontitis and sphenoid sinusitis are described. A 65-year-old woman presented with right proptosis, headache, and fever. A 74-year-old woman presented with left periorbital swelling. In both patients, MRI with gadolinium showed expansion of the bilateral cavernous sinus and diffuse dilatation of the SOV with non-enhancement of central thrombus, which indicated CST. The condition was complicated by brain abscess, meningitis, and ischemic stroke. These conditions were improved by antibiotic treatment, but one patient underwent exenteration of the orbit due to orbital rupture during hospitalization.

    A sinusitis caused by Cochliobolus hawaiiensis (anamorph: Bipolaris hawaiiensis) was diagnosed in metropolitan France in a patient originating from New Caledonia. The patient completely recovered after surgical treatment consisting in marsupialization of the mucoceles and removal of the fungus balls located in the left nasal cavity and the left maxilla and ethmoid sinuses. One year after, both endoscopic examination and CT scan of the sinuses were normal. Various clinical presentations of diseases associated with C. hawaiiensis have been reported. A review of the literature indicates that although C. hawaiiensis is very rarely reported in Europe, it is one of the major rhinosinusitis agents in areas with a relatively warmer climate, such as India or Southwestern USA. This is the first report of a sinusitis caused by C. hawaiiensis diagnosed in France, with a total recovery outcome.

    2012-01-31

    BACKGROUND: Treatment of pilonidal sinus disease is controversial. Many claim policy of marsupialisation and healing by secondary intention. This is demanding in terms of nursing care and time lost from work. AIMS: To examine outcome of excision and primary closure of chronic pilonidal disease on recurrence rate and patient\\'s daily activities. PATIENTS AND METHODS: One hundred and fourteen consecutive elective patients who had excision and primary closure of pilonidal sinus disease were reviewed. The demographic data and the post-operative outcome were studied. RESULTS: The recurrence of pilonidal sinus was noted in 9% of patients, wound breakdown occasioning delayed healing in 9%, patients able to drive by day 16 on average. The mean time to return to work was 20.5 days; duration of analgesia, 2.4 days; and duration of antibiotic treatment, 4.7 days. CONCLUSION: Excision and primary closure of chronic pilonidal sinus has low recurrence rate with early return to activities. Primary closure appears to be a cost-effective option for uncomplicated pilonidal sinus disease.

    Aim: To correlate cerebral cavernous malformations (CCMs) disease aggressiveness with peripheral blood biomarkers hypothesized mechanistically. Patients & methods: A prospective case–control study enrolled 43 CCM patients, where 25-(OH) vitamin D, HDL and non-HDL cholesterol, CRP plasma levels and leukocyte ROCK activity were correlated with parameters of disease aggressiveness reflecting chronic and acute domains. Results: Patients with one or more features of chronically aggressive disease (early age at symptom onset, two or more symptomatic bleeds, high lesion burden) had significantly lower 25-(OH) vitamin D and non-HDL cholesterol levels in comparison to patients without these features. Conclusion: Validation of these biomarkers and their potential treatment modulation may influence the clinical care of patients with CCM disease. PMID:26861901

    2004-01-01

    The surgical approach to pilonidal sinus disease is open to debate. This prospective, randomized study was aimed to compare the outcome of the excision and marsupialization and the sinus excision technique by radiofrequency. Thirty patients of chronic pilonidal sinus disease were randomly assigned to radiofrequency sinus excision (n = 15) and excision and marsupialization (n = 15). The parameters measured included intraoperative and postoperative data, wound-related complications, and recurrence. Patient satisfaction score was assessed at 1-year follow-up. The operation time, postoperative pain, hospital stay, and off work periods were significantly less (p < 0.05) in the technique employing radiofrequency surgery. At 1-year follow-up, there was 1 case of recurrence in each group. The patients from radiofrequency group expressed better satisfaction than the patients operated by marsupialization. Radiofrequency sinus excision technique needs a shorter hospital stay with reduced postoperative pain and early resumption to work in comparison with the sinus excision and marsupialization technique.

    Most patients with Cystic fibrosis (CF) have chronic sinus disease which may require multiple sinus surgeries and antibiotic courses. Ivacaftor can improve lung function, lower sweat chloride levels and improve weight by targeting the primary defect, a faulty gene and its protein product, cystic fibrosis transmembrane conductance regulator (CFTR) in patients with the G551D mutation. Its role in improving sinus disease has not been evaluated. The objective of this study was to evaluate efficacy of ivacaftor in improving CF related sinus disease. Observational study. Twelve patients with cystic fibrosis and a G551D-CFTR mutation. Twelve patients with a G551D-CFTR mutation were monitored for at least one year before and after starting ivacaftor. Sinus disease progression was monitored by comparing computed tomography (CT) of sinuses before and at one year on therapy. Hospital admissions, pulmonary exacerbations, weight, BMI and lung function were also compared. Median age was 17 years (range 10-44). Weight, BMI, FEV1 significantly increased and sweat chloride significantly decreased by six months on ivacaftor therapy. CT of the sinuses in all patients improved. Seven patients had severe sinus disease, improved to moderate in three and mild in remaining four. Four patients had moderate disease which improved to mild in all. One patient had normal sinus CT before and after the therapy. Patients with CF and G551D mutation, within 6 months of starting ivacaftor had significant improvements in weight, BMI and mean % FEV1. Significant lessening of underlying sinus disease measured by CT scan was noted, suggesting a disease modifying effect. © 2014 John Wiley & Sons Ltd.

    There is no easy to use scoring system for computed tomography (CT) scans of the sinuses that is specific to cystic fibrosis (CF). We propose a simple and easily implemented scoring system to quantify severity of sinus disease in adults with CF. Case series with chart review. Academic tertiary-care referral center. Sixty-nine adult patients with CF and 50 age-matched controls. We validated a scoring system for CF sinus disease. The CT scans were interpreted by 3 physicians on 2 separate sittings. Parameters include maxillary opacification, nasal obstruction, lateral nasal wall displacement, uncinate process absence/demineralization, and presence/absence of mucocele. Patients with CF aged 21 to 30 years (mean = 24.7 ± 2.49). In CF cohort (n = 69), intrarater reliability for the 10 CT categories ranged from .70 to 1.00. Twenty-six (87%) were in the excellent range, and the remaining 4 (13%) were evaluated as good. In the non-CF cohort (n = 50), reliabilities ranged from .44 to 1.00. Twenty-seven (90%) were in the excellent range. For interrater reliability, in the CF cohort, 10 CT categories across the 3 raters ranged from .55 to 1.00. Excellent reliability was achieved in 15 (50%) of the observations. In the non-CF cohort, reliabilities ranged from .44 to 1.00. A novel and easy to use CT scoring system for CF sinus disease in adults was validated with inter- and intrarater reliability. This new CF sinus disease-specific scoring system can be used by clinicians, surgeons, and radiologists. © The Author(s) 2016.

    Visual disturbances associated with isolated sphenoid sinus inflammatory diseases (ISSIDs) are easily misdiagnosed due to the nonspecific symptoms and undetectable anatomical location. The main objective of this retrospective case series is to investigate the clinical features of visual disturbances secondary to ISSIDs. Clinical data of 23 patients with unilateral or bilateral visual disturbances secondary to ISSIDs from 2004 to 2014 with new symptoms were collected. Collected data including symptoms, signs, neuroimaging and pathologic diagnosis were analyzed. There were 14 males and 9 females, and their ages ranged from 31 to 83 years. Fifteen patients suffered blurred vision and 11 patients suffered binocular double vision, including 3 patients who had unilateral visual changes and diplopia simultaneously. Headache was observed in 18 patients, and orbit pain/ocular pain in 8 patients. Other presenting symptoms included ptosis (4 patients) and proptosis (1 patient). Only 5 patients had nasal complaints. The corrected visual acuities were between NLP to 20/20. Patients with diplopia included 5 with unilateral oculomotor nerve palsy and 6 with unilateral abducens nerve palsy. All patients performed orbital/sinus/brain radiologic examination and found responsible lesions in sphenoid sinus. All patients underwent endoscopic sinus surgery, and 9 patients were found to suffer sphenoid mucocele, 9 with fungal sinusitis, and 5 with sphenoid sinusitis. Visual disturbances improved in 6 patients, and all the patients with diplopia had a postoperative recovery. Visual disturbances resulting from ISSIDs are relatively uncommon, but it is crucial that the patient with new vision loss or diplopia and persistent headache or orbit pain be evaluated for the possibility of ISSIDs especially before corticosteroid administration.

    The patient is a 30-year-old man who has suffered from recurrent attacks of tonsilitis, oral aphthae and scrotal ulcerations, erythema nodosum and thrombophlebitis. In April, 1980, he gradually developed headache and visual disturbance. On April 14, 1980, he was pointed out remarked bilateral choked disc by an ophthalmologist and then admitted to the Miyazaki Medical College Hospital. On admission to our service, he showed atypical symptoms of Behçet's disease, namely, oral aphthae and scrotal ulcerations, erythema nodosum and bilateral choked disc. Laboratory data demonstrated hyperimmunoglobulinemia, increased clotting factors and decreased fibrinolytic activity. Immunogenetically, HLA BW51 type was demonstrated. The angiograms showed complete obstructions of the superior sagittal sinus and the common trunk of the femoral artery. Histological examination of the skin lesion demonstrated atypical chronic inflammation and thrombophlebitis. A diagnosis of atypical Vasculo-Behçet's disease was made. The response to the steroid therapy was dramatic, though the fibrinolytic drugs, anticoagulants and vasodilators were not effective. Thrombophlebitis is a well recognized complication of Behçet's disease occurring in major vessels, however thrombosis of the dural sinus has rarely reported. This case may be the first one which had superior sagittal sinus thrombosis with Vasculo-Behçet's disease in literature. We discussed the mechanism of the thrombogenesis, the relationship to HLA, the coexistence of Neuro-Behçet's disease and the therapy of Vasculo-Behçet's disease.

    Full Text Available Two cases of giant intracavernous aneurysms treated by high flow bypass with saphenous vein graft between the external carotid artery (ECA and branches of the middle cerebral artery (MCA are presented. Very often these aneurysms are unclippable because they are fusiform or have a large neck. Occlusion of the internal carotid artery (ICA is the treatment of choice in many cases. This procedure has however a high risk of brain infarction. Revascularization of the brain by extra-intracranial anastomosis between the superficial temporal artery (STA and branches of the MCA is frequently performed. This procedure provides however a low flow bypass and brain infarction may occur. We report two cases of giant cavernous sinus aneurysms treated by high flow bypass and endovascular balloon occlusion of the ICA. Immediate high flow revascularization of MCA branches was achieved and the patients showed no ischemic events. Follow-up of 8 and 14 months after operation shows patency of the venous graft and no neurological deficits. Angiographic control examination showed complete aneurysm occlusion in both cases.Aneurismas gigantes da porção intracavernosa da artéria carótida interna frequentemente são inoperáveis por serem fusiformes ou apresentarem colo muito largo.

    Chronic sinusitis is a common disease that encompasses a number of syndromes that are characterized by sinonasal mucosal inflammation. Chronic sinusitis can be defined as two or more of the following symptoms lasting for more than 12 consecutive weeks: discolored rhinorrhea, postnasal drip, nasal obstruction, facial pressure or pain, or decreased sense of smell. Chronic sinusitis is further classified as chronic sinusitis with polyposis, chronic sinusitis without polyposis, or allergic fungal sinusitis using physical examination, and histologic and radiographic findings. Treatment methods for chronic sinusitis are based upon categorization of the disease and include oral and inhaled corticosteroids, nasal saline irrigations, and antibiotics in selected patients. Understanding the various forms of chronic sinusitis and managing and ruling out comorbidities are key to successful management of this common disorder.

    2014-01-01

    To analyze available evidence on the incidence of anatomical variations or disease of the maxillary sinuses as identified by cone beam computed tomography (CBCT) in dentistry. A focused question was developed to search the electronic databases MEDLINE, EMBASE, the Cochrane Oral Health Group Trials Register, and CENTRAL and identify all relevant papers published between 1980 and January 19, 2013. Unpublished literature at ClinicalTrials.gov, in the National Research Register, and in the Pro-Quest Dissertation Abstracts and Thesis database was also included. Studies were included irrespective of language. These results were supplemented by hand and gray literature searches. Twenty-two studies were identified. Twenty were retrospective cohort studies, one was a prospective cohort study, and one was a case control study. The main indication for CBCT was dental implant treatment planning, and the majority of studies used a small field of view for imaging. The most common anatomical variations included increased thickness of the sinus membrane, the presence of sinus septa, and pneumatization. Reported sinus disease frequency varied widely, ranging from 14.3% to 82%. There was a wide range in the reported prevalence of mucosal thickening related to apical pathology, the degree of lumenal opacification, features of sinusitis, and the presence of retention cysts and polyps. More pathologic findings in the maxillary sinus were reported in men than in women, and the medial wall and sinus floor were most frequently affected. CBCT is used primarily to evaluate bony anatomy and to screen for overt pathology of the maxillary sinuses prior to dental implant treatment. Differences in the classification of mucosal findings are problematic in the consistent and valid assessment of health and disease of the maxillary sinus.

    In this study we assessed patient outcomes after complete endoscopic sinus surgery (ESS) and aspirin desensitization for patients with aspirin-exacerbated respiratory disease (AERD). A retrospective chart review was conducted for patients with aspirin challenge-proven AERD who underwent complete ESS followed by aspirin desensitization. Outcomes assessed included need for revision surgery and quality-of-life measures using the 22-item Sino-Nasal Outcomes Test (SNOT-22). Data were collected preoperatively, postoperatively prior to desensitization, and then at intervals post-desensitization through 30 months after aspirin desensitization. A longitudinal linear mixed-effects model was used for data analysis. Thirty-four patients met the inclusion criteria for this study. Thirty-two patients successfully completed aspirin desensitization and were subsequently followed for 30 months after desensitization. Two patients were unable to complete desensitization. Five patients discontinued aspirin maintenance therapy due to gastrointestinal and respiratory side effects. Within the follow-up period, there were only 3 (9.4%) revision sinus surgeries. Notably, 1 of these revision cases occurred in a patient who had discontinued aspirin maintenance therapy. After surgical treatment and prior to desensitization patients had significant reductions in SNOT-22 scores. Our results demonstrate that total SNOT-22 scores remained statistically unchanged from immediate post-desensitization throughout the 30-month follow-up period. Complete sinus surgery followed by timely aspirin desensitization and maintenance therapy is an effective combination in the long-term management of sinus disease in patients with AERD. © 2017 ARS-AAOA, LLC.

    Full Text Available Complex cavernous sinus fistulae (CCF are still a technical challenge to neurovascular team. The most commonly performed treatment consists in endovascular embolization of the lesion through an arterial or venous approach. Not always these conventional routes are feasible, requiring alternative routes. We report a case of a 44-year-old woman with a complex indirect (Barrow D carotid cavernous sinus fistula treated by two interventional sessions that imposing a retrograde direct transvenous approach via the superior ophthalmic vein.

    Carotid cavernous fistulae (CCF) are defined as abnormal connections between the carotid circulation and cavernous sinus. CCFs can be categorized as being direct or indirect. Direct CCFs are usually associated with trauma, whereas indirect CCFs are associated with revascularization following cavernous sinus thrombosis. We present a case of a 53-year-old male who presented with tinnitus, proptosis, conjunctivitis, and blurry vision. The patient had a recent endovascular transvenous embolization that was only partially successful, with a residual carotid cavernous fistula draining to the left superior ophthalmic vein and multiple cortical veins. A physical examination of the patient showed elevated intraocular pressures bilaterally. The patient had a high-flow indirect carotid cavernous fistula with bilateral superior ophthalmic vein (SOV) and retrograde cortical vein drainage. The SOV was punctured with a micropuncture needle and was used to successfully gain access to the cavernous sinus. Multiple coils were placed in the posterior aspect of the sinus until there was complete occlusion of venous flow. Coils were packed up to the posterior aspect of the orbit near the junction of the cavernous sinus with the SOV, and the embolization was successful. Indirect CCFs have gradual onset and are usually low-flow. Low-flow CCFs might improve with medical management.Some CCFs may cause ocular manifestations and can be symptomatically managed with prism therapy or ocular patching for diplopia, lubrication for keratopathy, or topical agents for elevated intraocular pressures. However, patients presenting with persistent ocular morbidity may require surgical or endovascular intervention.

  17. Successful endoscopic management with Mitomycin C application for sinusitis with orbital cellulitis

    Directory of Open Access Journals (Sweden)

    Anil S Harugop

    2013-01-01

    Full Text Available Background: Sinusitis with orbital complication is a potentially fatal disease that has been known since the days of Hippocrates. Primary sinus infection is the most common cause of orbital cellulitis. It is an emergency that threatens not only vision but also life from complications such as meningitis, cavernous sinus thrombosis, and brain abscess. Surgical intervention is mandatory whenever antibiotic treatment fails. There are two surgical options for the drainage, an external approach via a Lynch incision and an intranasal endoscopic procedure. Materials and Methods: Five patients with orbital cellulitis secondary to acute on chronic rhinosinusitis were included in the study from the period of 2010 - 2011. All five patients did not respond to medical management and hence underwent endoscopic sinus surgery with treatment of orbital pathology. At the end of the surgical procedure Mitomycin C in a concentration of 0.4mg/ml was applied with a cottonoid for a period of 4 minutes to prevent chance of adhesion formation. Results: In this series 3 females and 2 male patient with orbital cellulitis secondary to acute on chronic rhinosinusitis underwent endoscopic sinus surgery with treatment of orbital pathology. All 5 patients showed subjective and objective improvement within one week of endoscopic management. Conclusion: Though antibiotics have altered the course of sinusitis, its grave complications still persist in our environment. The excellent results and the absence of any major complications of endoscopic sinus surgery and drainage of abscess with application of Mitomycin C can be recommended as the preferred surgical technique.

    Purpose Upper and lower respiratory tract pathologies are believed to be interrelated; however, the impact of upper airway inflammation on lung function in subjects without lung disease has not been evaluated. This study investigated the association of CT finding suggesting chronic sinusitis and lung function in healthy subjects without lung disease. Methods This was a retrospective study of prospectively collected data from 284 subjects who underwent a pulmonary function test, bronchial provocation test, rhinoscopy, and osteomeatal unit computed tomography offered as a private health check-up option. Results CT findings showed that the sinusitis group had a significantly lower FEV1/FVC ratio than subjects without sinusitis finding (78.62% vs 84.19%, P=0.019). Among the sinusitis group, subjects classified by CT findings as the extensive disease group had a slightly lower FEV1/FVC than those of the limited disease group (76.6% vs 79.5%, P=0.014) and the associations were independent of the presence of airway hyperresponsiveness. The subjects with nasal polyp had also lower FEV1 and FEV1/FVC than subjects without nasal polyp (FEV1: 100.0% vs 103.6%, P=0.045, FEV1/FVC: 77.4% vs 80.0%, P=0.005). Conclusions CT findings suggesting chronic sinusitis and nasal polyp were associated with subclinical lower airway flow limitation even in the absence of underlying lung disease. PMID:24991454

    To show a rare case of Cushing's disease and possible cause of failed transsphenoidal surgery. We report on a 50-year-old woman suffering from ACTH-dependent Cushing's syndrome. Endocrinological work-up including low-dose/high-dose dexamethasone test (Liddle-test) and CRH test were clearly compatible with pituitary origin. Although an MRI showed no pituitary tumor, CRH-stimulated petrosal sinus sampling revealed a significant central-peripheral gradient in ACTH concentrations, rendering Cushing's disease very likely. The patient underwent transsphenoidal surgery with negative exploration of the pituitary gland. After intraoperative re-evaluation of the preoperative MRI, a "polyp" at the bottom of the sphenoid sinus was identified. The intraoperative microscopic aspect as well as instantaneous sections and cytology of a biopsy confirmed an adenoma, which was then removed. Histological analysis demonstrated an ACTH-producing pituitary adenoma adjacent to respiratory mucous membrane consisting of ciliated epithelium with submucous connective tissue. Postoperatively, ACTH concentrations were decreased and intermittent hydrocortisone substitution treatment was initiated. At the 3-month follow up, Cushing's stigmata were found to be alleviated and the hydrocortisone dosage could be reduced. Ectopic pituitary adenoma tissue causing Cushing's disease is extremely rare but a potential cause for surgical failure or re-evaluation.

    Cerebral cavernous malformations (CCMs) are hemorrhagic brain lesions, where murine models allow major mechanistic discoveries, ushering genetic manipulations and preclinical assessment of therapies. Histology for lesion counting and morphometry is essential yet tedious and time consuming. We herein describe the application and validations of X-ray micro-computed tomography (micro-CT), a non-destructive technique allowing three-dimensional CCM lesion count and volumetric measurements, in transgenic murine brains. We hereby describe a new contrast soaking technique not previously applied to murine models of CCM disease. Volumetric segmentation and image processing paradigm allowed for histologic correlations and quantitative validations not previously reported with the micro-CT technique in brain vascular disease. Twenty-two hyper-dense areas on micro-CT images, identified as CCM lesions, were matched by histology. The inter-rater reliability analysis showed strong consistency in the CCM lesion identification and staging (K=0.89, p<0.0001) between the two techniques. Micro-CT revealed a 29% greater CCM lesion detection efficiency, and 80% improved time efficiency. Serial integrated lesional area by histology showed a strong positive correlation with micro-CT estimated volume (r(2)=0.84, p<0.0001). Micro-CT allows high throughput assessment of lesion count and volume in pre-clinical murine models of CCM. This approach complements histology with improved accuracy and efficiency, and can be applied for lesion burden assessment in other brain diseases. Copyright © 2016 Elsevier B.V.

    In this study, we were focused on the differences between certain circulating cytokine levels in patients with or without sinus arrhythmia, according to the median IL-6 level. All patients were stable with regards to symptoms and therapy for at least one month prior to the measurements conducted within this study.Exclusion criteria were: patients with sleep apnea, asthma, respiratory insufficiency of any genesis, active infection, allergy, inflammatory diseases, cancer, diabetes of any type and treatment with anti-inflammatory drugs. The study was approved by the Institutional Review Board. All recruited patients gave their verbal and written consent for participation in the study. The study group consisted of 74 patients divided into two groups: with (38) and without sinus arrhythmia but with diagnosed coronary artery disease (36). Sinus arrhythmia was confirmed by 24h Holter monitoring. From all test parameters only cytokines IL-2, IL-8, IL-10, IL-17 and IL-18, showed statistically significant increasing in patients with statistically higher IL-6 levels. It is possible that IL-6 may not be a marker for the selection of patients with sinus arrhythmia or coronary artery disease. The findings indicate that IL-6 represents a reliable indicator for increased expression of IL-2, IL-8, IL-10, IL-17 and IL-18 in patients with sinus arrhythmia or coronary artery disease. Further studies in a large number of patients would be necessary to confirm our observations. Copyright © 2016 Elsevier Inc. All rights reserved.

  2. DURAL CAROTID-CAVERNOUS FISTULAS

    Directory of Open Access Journals (Sweden)

    2002-12-01

    Full Text Available Background. Dural carotid-cavernous sinus fistulas (CCF are communications fed by meningeal branches of the intracavernous internal carotid artery (ACI or/and external carotid artery (ACE. In contrast to typical CCF, the arteriovenous shunting of blood is usually low flow and low pressure. Spontaneous dural CCF are more common in postmenopausal women. Aetiology is unknown, but congenital malformation or rupture of thin-walled dural arteries within venous sinuses is believed to be the cause.Case reports. 3 cases lacking the typical clinical signs of CCF who had been treated as chronic conjunctivitis, myositis of the extraocular muscle and orbital pseudotumour are presented. Clinical presentation depends on the direction and magnitude of fistular flow and on the anatomy of the collateral branches. If increased blood flow is directed anteriorly in ophthalmic veins the signs of orbito-ocular congestion are present (»redeyed shunt syndrome«. Drainage primarly in the inferior petrosal sinus may cause painful oculomotor and abducens palsies without signs of ocular congestion (»white-eyed shunt syndrome«. Also different therapeutic approaches as well as possible complications are described.Conclusions. For definite diagnosis angiography is obligatory and is also therapeutic as one third to one half of dural CCF close spontaneously. Because of potential severe eye and systemic complications, surgical intervention is indicated only in cases with uncontrolled secondary glaucoma and hypoxic retinopathy.

    Familial Cerebral Cavernous Malformation type 1 (CCM1) is an autosomal dominant disease caused by mutations in the Krev Interaction Trapped 1 (KRIT1/CCM1) gene, and characterized by multiple brain lesions. CCM lesions manifest across a range of different phenotypes, including wide differences in lesion number, size and susceptibility to intracerebral hemorrhage (ICH). Oxidative stress plays an important role in cerebrovascular disease pathogenesis, raising the possibility that inter-individual variability in genes related to oxidative stress may contribute to the phenotypic differences observed in CCM1 disease. Here, we investigated whether candidate oxidative stress-related cytochrome P450 (CYP) and matrix metalloproteinase (MMP) genetic markers grouped by superfamilies, families or genes, or analyzed individually influence the severity of CCM1 disease. Clinical assessment and cerebral susceptibility-weighted magnetic resonance imaging (SWI) were performed to determine total and large (≥5mm in diameter) lesion counts as well as ICH in 188 Hispanic CCM1 patients harboring the founder KRIT1/CCM1 'common Hispanic mutation' (CCM1-CHM). Samples were genotyped on the Affymetrix Axiom Genome-Wide LAT1 Human Array. We analyzed 1,122 genetic markers (both single nucleotide polymorphisms (SNPs) and insertion/deletions) grouped by CYP and MMP superfamily, family or gene for association with total or large lesion count and ICH adjusted for age at enrollment and gender. Genetic markers bearing the associations were then analyzed individually. The CYP superfamily showed a trend toward association with total lesion count (P=0.057) and large lesion count (P=0.088) in contrast to the MMP superfamily. The CYP4 and CYP8 families were associated with either large lesion count or total lesion count (P=0.014), and two other families (CYP46 and the MMP Stromelysins) were associated with ICH (P=0.011 and 0.007, respectively). CYP4F12 rs11085971, CYP8A1 rs5628, CYP46A1 rs10151332, and

    To review published evidence of Limberg flap (LF) use in pilonidal sinus disease (PSD). We also included our local experience of LF. Medline and Embase database were searched for the words 'pilonidal, sinus, Limberg, flap'. Non-English articles and those not-related to our scope of search were omitted. We included a retrospective study of patients underwent LF in our district hospital. Data including length of hospital stay, post-operative complications and recurrence were collected. Literature review revealed 68 studies (22 case series, 35 comparative studies, nine RCTs and two meta-analyses). Recurrence rate was 0-7.4% in case series. Recurrence rate in comparative studies was 0-8.3%, compared to 4-37.7% for primary closure and 0-11% for Karydakis flap. RCTs showed that LF or its modification is superior to primary closure, with comparable results to Karydakis flap. About 26 patients included in the cohort study (16 male, average age 27 years). Six patients presented with recurrent disease. Post-operative length of hospital stay was four to seven days. Post-operative complication rate was 11.5% - [two partial wound dehiscence, one wound infection]. Recurrence rate was 7.7%. Average follow-up was 18 months. Limberg flap presents a safe and effective method that can be offered for patients with primary or recurrent PSD.

    Pacing mode in sinus node disease (SND) is one of controversies in cardiac pacing. We evaluated atrial pacing mode (AAI) in SND patients (pts). Between 1985 and 1994 AAI pacemaker was inserted in 179 pts due to symptomatic SND of varied etiology. The majority of pts (91.6%) were free from syncopal episodes after AAI implantation, in 15 pts (8.4%) syncopes were occasionally observed due to disturbances in pacemaker function, AVB III degrees, vaso-vagal syndrome, orthostatic hypotonia or atherosclerotic insufficiency of the cerebral circulation. In 49 (51%) out of 96 pts with brady-tachy syndrome (BTS), episodes of supraventricular tachyarrhythmia were not observed after AAI insertion and in the majority of the remaining pts the frequency of the episodes decreased significantly. Chronic atrial fibrillation developed in 5 (5.2%) pts. In some of the pts the symptoms related to chronic heart failure decreased or disappeared. A reoperation was performed in 44 (24%) pts due to electrode dislocation or fracture, atrio-ventricular conduction disturbances, an increase in pacing threshold or due to local infections. During the follow-up period 13 (7.3%) pts died of reasons unrelated to cardiac pacing therapy. In the majority of SND pts AAI pacing mode prevents from syncopal episodes caused by sinus node disfunction. It decreases the symptoms of heart failure in SND pts and stabilizes the sinus rhythm in the majority of BTS pts. Complications accompanying AAI do not post a major threat for the pts and can be easily resolved. They should by no means discourage from AAI implantation in SND.

    2001-02-01

    A girl with Down's syndrome, moyamoya disease and sagittal sinus thrombosis is described. She was diagnosed after acute neurological deterioration by MRI and angiography. Recombinant tissue plasminogen activator (r-TPA) was injected locally to recanalise the thrombus. The patient's condition significantly improved and she was discharged. After 2 years of follow-up the child remains asymptomatic. Moyamoya syndrome and cerebral venous thrombosis should not be overlooked as a cause of acute neurological deterioration in a child with Down's syndrome. MRA appears to be a safe and accurate alternative to traditional angiography for the diagnosis of moyamoya disease. Local fibrinolysis with r-TPA is the treatment of choice for cerebral venous thrombosis due to its safety and efficacy. (orig.)

    2014-08-01

    Full Text Available Introduction Rosai-Dorfman disease (RDD is a rare histiocytic proliferative disorder of unknown etiology. Usually it presents with massive painless cervical lymph node enlargement. Histologically, it shows proliferation of distinctive histiocytic cells that demonstrate emperipolesis in the background of a mixed inflammatory infiltrates. Immunohistochemically, the cells are positive for markers such as CD68 and S100. Objective To report a case of a 12-year-old patient with multiple sites of cervical lymphadenitis, which was diagnosed as RDD histopathologically as well as immunohistologically. Resumed Report A 12-year-old girl presented with multiple painless sites of cervical lymphadenitis without any systemic and other ear, nose, and throat manifestations. The biopsy report of the lymph node showed dilatation of the sinuses, filled with histiocytes having foamy cytoplasm. Many of the histiocytes were engulfing mature lymphocytes. The sinus histiocytes were strongly positive for S-100 protein. Conclusion RDD must be considered in the differential diagnosis of massive or multiple lymphadenopathies.

    Novak, G.Ya.; Bukhman, A.A.; Chestukhin, V.V. (Nauchno-Issledovatel' skij Inst. Transplantologii i Iskusstvennykh Organov, Moscow (USSR))

    The method of radiocontrast examination employed in Peyronil's disease is described. One hundred and twenty-six patients were examined with the help of this method. The results add to the knowledge of the size, localization and the spread of the indurative process as compared to the palpatory data. Cavernosography makes it possible to observe over time the disease regression under different modes of treatment. Hence, it might be considered as an objective method of assessment of various types of the penis fibroplastic induration treatment.

    Full Text Available Titanium plane screw fixation of the frontal sinus is an approach used by otolaryngologists to obliterate this space in an attempt to reduce sinus infections. In this case, however, the titanium used became a nidus of infection which cultured the fungus Paecilomyces. The patient also had a hypersensitivity reaction to mold with positive skin tests and IgE, as well as eosinophilic esophagitis. Treatment entailed anti-fungals, anti-IgE, and fungal immunotherapy to multiple fungal antigens prevalent to the geographic region. The patient also had aspirin exacerbated respiratory disease which responded to aspirin desensitization. Her symptoms resolved after 3 months.

    Because magnetic resonance imaging (MRI) fails to detect many adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas, inferior petrosal sinus sampling (IPSS) is considered the gold standard to differentiate Cushing disease (CD) from ectopic ACTH secretion syndrome (EAS). Some authors have suggested internal jugular vein sampling (IJVS) as an alternative to IPSS. We simultaneously compared IJVS to IPSS in 30 consecutive patients referred for ACTH-dependent Cushing syndrome and equivocal MRI exams. Five sites were simultaneously sampled in each patient (right and left IPS, right and left IJV, and femoral vein) before and after the administration of corticotrophin-releasing hormone or desmopressin. The test was considered consistent with CD when the IPS to peripheral ratio was >2 at baseline or >3 after stimulus and the IJV to peripheral ratio was >1.7 at baseline or >2 after stimulus. In 27 of 30 patients, IPSS results were consistent with a central source of ACTH. Two of the other 3 patients had EAS (one lung carcinoid and one occult), and 1 patient had pathology-proven CD. The sensitivity of IPSS was 96.4%. Only 64.2% of these patients had results meeting criteria for a central source of ACTH by IJVS criteria. Twenty patients with centralizing IPPS have undergone pituitary surgery. Of these, the central origin of excessive ACTH was confirmed with certainty in 16 patients. Among these 16 patients, the IPSS sensitivity was 93.8%, whereas 5 patients had false-negative IJVS (68.7% sensitivity). These results do not support the routine use of IJVS in establishing if the pituitary is the source of excessive ACTH. ACTH = adrenocorticotropic hormone CD = Cushing disease CRH = corticotrophin-releasing hormone CS = Cushing syndrome DDAVP = desmopressin EAS = ectopic ACTH secretion IJVS = internal jugular vein sampling IPSS = inferior petrosal sinus sampling JVS = jugular venous sampling MRI = magnetic resonance imaging.

    105 patients with acute and chronic inflammation of the paranasal sinuses were exposed to the radiation of the semiconductor laser Uzor using gallium arsenide. The treatment combined antiinflammatory drugs with vasoconstrictive nasal drops, maxillary puncture and laser radiation. Intolerance to laser effects was registered in 3 patients. The course of treatment included 5-6 sessions in acute sinusitis and 10 sessions in chronic sinusitis. Laser therapy was found effective as it reduced the time of treatment by 1-2 days.

    A carotid-cavernous fistula (CCF) is an abnormal communication between arteries and veins within the cavernous sinus and may be classified as either direct or dural. Direct CCFs are characterized by a direct connection between the internal carotid artery (ICA) and the cavernous sinus, whereas dural CCFs result from an indirect connection involving cavernous arterial branches and the cavernous sinus. Direct CCFs frequently are traumatic in origin and also may be caused by rupture of an ICA aneurysm within the cavernous sinus, Ehlers-Danlos syndrome type IV, or iatrogenic intervention. Causes of dural CCFs include hypertension, fibromuscular dysplasia, Ehlers-Danlos type IV, and dissection of the ICA. Evaluation of a suspected CCF often involves non-invasive imaging techniques, including standard tonometry, pneumotonometry, ultrasound, computed tomographic scanning and angiography, and/or magnetic resonance imaging and angiography, but the gold standard for classification and diagnosis remains digital subtraction angiography. When a direct CCF is confirmed, first-line treatment is endovascular intervention, which may be accomplished using detachable balloons, coils, liquid embolic agents, or a combination of these tools. As dural CCFs often resolve spontaneously, low-risk cases may be managed conservatively. When invasive treatment is warranted, endovascular intervention or stereotactic radiosurgery may be performed. Modern endovascular techniques offer the ability to successfully treat CCFs with a low morbidity and virtually no mortality.Eye advance online publication, 3 November 2017; doi:10.1038/eye.2017.240.

    Purpose: Since feeding arteries from both the internal and external carotid artery are common, cavernous fistulas of Barrow type D are difficult to treat. Embolization using the transarterial approach is considered to be the standard therapy. However, it is often impossible to embolize feeders from the internal carotid artery. The transorbital approach after anterior orbitotomy through the ophthalmic vein is an alternative in this complex situation. The following reports our experience with three female patients who underwent transvenous embolization. Procedural success was documented using standardized MRI and clinical reevaluation. Materials and Methods: Three female patients between 57 and 78 years of age were diagnosed with carotid cavernous fistulas by conventional angiogram. All patients were suffering from exophthalmus and visual impairment. Two patients showed secondary glaucoma and diplopia. In one patient we performed a technically successful transarterial embolization using particles, but no relevant improvement of the patient's condition was seen. Transfemoral transvenous access via the sinus petrosus was not possible in any patient. All patients were then embolized via the ophthalmic vein using GDC detachable coils. All patients were clinically reevaluated by an ophthalmologist. Also a standardized MRI was performed for documentation. Follow-up was performed for the first patient for 32 months, for the second patient for 34 months and for the third patient for 50 months. Results: Transvenous embolization was technically successful in all three cases. Clinical symptoms disappeared rapidly. Postprocedural MRI showed a symmetric diameter of the ophthalmic vein. Venous congestion of the orbit caused by fatty tissue edema regressed completely. Contrast-enhanced magnetic resonance angiography showed normal arterial vessels without evidence of fistula. (orig.)

    We conducted a retrospective analysis of 71 selected pediatric patients, aged 1 to 7 years, which were submitted to helical computed tomography examination of the paranasal sinuses in the period between March, 1997 and April, 1998 due to recurrent acute sinusitis and chronic sinusitis. Clinical and helical computed tomography findings were compared by evaluating the pneumatization of the paranasal sinuses, ostiomeatal complexes, anatomic variants, the status of mucosal surface and lesion extension. The most common CT findings were total or partial opacification of one or more paranasal cavities (92.9%), followed by mucosal thickening (67.6%). In the majority of cases there was association between sinusitis and ostiomeatal obstruction. Anatomic variants were identified from the age of one year. The most common anatomic variant was septonasal deviation (14.1%) that was associated to sinusitis in about 71% of the patients. (author)

    The incidence of fungal sinusitis is subjected to significant geographical variation. Basically, invasive and non-invasive fungal sinusitis is distinguished. Invasive fungal sinusitis is observed mainly in immunocompromised hosts. The diagnopsis is based on positive fungus detection combined with characteristic clinical features. The treatment of invasive fungal sinusitis is based on surgical debridement and systemic antifungal therapy. Non-invasive fungal sinusitis is either treated with surgery alone or surgery combined with systemic steroid therapy. The majority of studies showed no benefit of postoperative antimycotic medical treatment in patients with non-invasive fungal sinusitis. © Georg Thieme Verlag KG Stuttgart · New York.

    The unique anatomy of the ethmoid sinuses makes it difficult to interpret ''soft-tissue clouding,'' especially on plain films. The clinical significance of isolated or generalized soft-tissue disease within ethmoid cells is unclear, and the patterns of bone erosion or remodeling must be relied on in establishing a specific differential diagnosis. Of 400 patients studied, 186 had inflammatory disease and 214 had tumors. Squamous cell carcinomas, metastases, and a few aggressive sarcomas were found almost exclusively to have bone destruction, while 94% of the remaining neoplasms were characterized by cavity remodeling. Further differentiation was sometimes possible because of the pattern and degree of tumor enhancement. Of the neoplasms, only the minor salivary gland lesions and neuromas had nonhomogeneous enhancement. Malignant lesions cannot be diagnosed with computed tomography (CT) unless bone destruction is present. Similarly, although the significance of persistent, benign-appearing soft-tissue disease during chemotherapy is unclear, tumor must always be suspected, even after many months of a stable CT appearance.

  9. Structural basis for the disruption of the cerebral cavernous malformations 2 (CCM2) interaction with Krev interaction trapped 1 (KRIT1) by disease-associated mutations.

    Familial cerebral cavernous malformations (CCMs) are predominantly neurovascular lesions and are associated with mutations within the KRIT1, CCM2, and PDCD10 genes. The protein products of KRIT1 and CCM2 (Krev interaction trapped 1 (KRIT1) and cerebral cavernous malformations 2 (CCM2), respectively) directly interact with each other. Disease-associated mutations in KRIT1 and CCM2 mostly result in loss of their protein products, although rare missense point mutations can also occur. From gene sequencing of patients known or suspected to have one or more CCMs, we discover a series of missense point mutations in KRIT1 and CCM2 that result in missense mutations in the CCM2 and KRIT1 proteins. To place these mutations in the context of the molecular level interactions of CCM2 and KRIT1, we map the interaction of KRIT1 and CCM2 and find that the CCM2 phosphotyrosine binding (PTB) domain displays a preference toward the third of the three KRIT1 NPX(Y/F) motifs. We determine the 2.75 Å co-crystal structure of the CCM2 PTB domain with a peptide corresponding to KRIT1(NPX(Y/F)3), revealing a Dab-like PTB fold for CCM2 and its interaction with KRIT1(NPX(Y/F)3). We find that several disease-associated missense mutations in CCM2 have the potential to interrupt the KRIT1-CCM2 interaction by destabilizing the CCM2 PTB domain and that a KRIT1 mutation also disrupts this interaction. We therefore provide new insights into the architecture of CCM2 and how the CCM complex is disrupted in CCM disease. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

    Full Text Available Carotid cavernous fistulae (CCF are abnormal communication between cavernous segment of the internal carotid artery and cavernous sinus. These entities are usually encountered in 0.2-0.8% of patients with traumatic skull base fractures. Traumatic cerebral aneurysms are rare and account for less than 1% of intracranial aneurysms. CCF due to ruptured intradural traumatic aneurysm is very rare and difficult to treat by surgical methods. We present one such case of a 40-year-old man with post-traumatic CCF due to a ruptured intradural aneurysm successfully treated with endovascular embolization.

    Posttraumatic carotid-cavernous fistula is a very rare complication that can occur in patients with craniomaxillofacial trauma. Symptoms involve headache, diplopia, ptosis of the upper lid, conjunctival chemosis, pulsating exophthalmos, and ophthalmoplegia. Diagnosis can be challenging because various pathologic entities can present with similar symptoms such as superior orbital fissure syndrome, orbital apex syndrome, retrobulbar hematoma, and cavernous sinus syndrome. However, accurate and early diagnosis is of utmost importance because treatment delay may lead to blindness or permanent neurologic deficits. In this article, a case of posttraumatic carotid-cavernous fistula that was twice misdiagnosed is presented. PMID:26269734

    The use of fibrin sealant in the management of pilonidal sinus disease has not previously been described in children. We present our experience of primary pit excision and use of fibrin sealant (PEF) and compare outcomes with lateralising flap procedures (LFP). A single centre retrospective case note review of all children who had undergone a definitive procedure for pilonidal sinus from August 2006 to Dec 2013 was performed using data expressed as median (range) and compared using Fisher's exact test. PPEF and twenty-six LFP. Two children had recurrence following primary PEF and had repeat PEF which was curative. Overall recurrence rates following PEF procedure were comparable to LFP (17% vs 21%; P=1.0). There were no wound dehiscences in the PEF group and one wound infection. There was one wound dehiscence and one wound infection in the LFP group. Median operative time for PEF was lower than LFP (20 vs 60 min, P=0.001). 83% of PEF procedures were performed as day cases. One child was lost to follow up, and two children progressed to adult services. We recommend PEF in children with pilonidal sinus disease as primary treatment and for recurrence. PEF has comparable recurrence and wound infection rates to LFPs, is performed as day case, has shorter anaesthetic times, and the risk of wound dehiscence is avoided. Copyright © 2015 Elsevier Inc.

    Full Text Available Pilonidal disease is a common chronic disorder mainly seen in the sacrococcygeal region, especially in young males. Many surgical treatment modalities have been suggested, but an ideal and widely accepted treatment has yet to be established. The aim of this study was to compare quality of life of patients treated with the sinotomy technique with quality of life of patients treated with surgical excision plus primary closure technique by means of quality of life questionnaire. The data of patients who had been treated for pilonidal sinus in our clinic from September 2010 to June 2012 were analyzed retrospectively. Forty patients were treated with sinotomy technique and 40 patients were treated with surgical excision plus primary closure technique. Time to return to work and to time to complete wound healing were evaluated. All patients were asked to fill the questionnaire after complete healing occurred. Postoperative complications were bleeding in 2.5%, infection in 3.75% and fever in 2.5% patients. There were no significant differences between the two groups in terms of complete healing (p=0.1 and sport times (p=0.1. There were significant differences between the groups in terms of length of hospital stay (p≤0.001, time off work (p≤0.001,times to sitting on toilet and walking without pain (p=0.002 and p≤0.001,respectively. The mean postoperative VAS scores were 5.2±3.2 and 2.8±2.2, respectively (p=0.02. The technique of sinotomy with good wound and surrounding skin care seems to be an ideal approach with high chance of cure. The patients returned to their routine in a short period of time.

    1995-12-01

    The conditions and occurrence of gas in crude oil stored in Strategic Petroleum Reserve, SPR, caverns is characterized in this report. Many caverns in the SPR show that gas has intruded into the oil from the surrounding salt dome. Historical evidence and the analyses presented here suggest that gas will continue to intrude into many SPR caverns in the future. In considering why only some caverns contain gas, it is concluded that the naturally occurring spatial variability in salt permeability can explain the range of gas content measured in SPR caverns. Further, it is not possible to make a one-to-one correlation between specific geologic phenomena and the occurrence of gas in salt caverns. However, gas is concluded to be petrogenic in origin. Consequently, attempts have been made to associate the occurrence of gas with salt inhomogeneities including anomalies and other structural features. Two scenarios for actual gas intrusion into caverns were investigated for consistency with existing information. These scenarios are gas release during leaching and gas permeation through salt. Of these mechanisms, the greater consistency comes from the belief that gas permeates to caverns through the salt. A review of historical operating data for five Bryan Mound caverns loosely supports the hypothesis that higher operating pressures reduce gas intrusion into caverns. This conclusion supports a permeability intrusion mechanism. Further, it provides justification for operating the caverns near maximum operating pressure to minimize gas intrusion. Historical gas intrusion rates and estimates of future gas intrusion are given for all caverns.

    OBJECTIVE Multiple cerebral cavernous malformations (CCMs) are rare lesions that occur in sporadic or familial form. Depending on the disease form, the natural history and treatment of the lesions strongly vary. Molecular analysis of an underlying germline mutation (CCM1-3) is the most sensitive screening method to distinguish between sporadic and familial cases. However, based on the different pathomechanisms that are believed to be involved in either form, significant distinctions in the CCM-associated cerebral venous angioarchitecture should be detectable. This has not been systematically studied. METHODS A consecutive series of 28 patients with multiple CCMs (681 total) diagnosed on 1.5-T MRI underwent genetic screening for CCM1-3 mutations and high-resolution susceptibility-weighted imaging (SWI) of the cerebral venous angioarchitecture with 7-T MRI. Imaging data were analyzed to examine the CCM-associated venous angioarchitecture. Results were correlated with findings of molecular analysis for CCM1-3 mutations. RESULTS Two different SWI patterns (sporadic and familial) were found. The presence of associated developmental venous anomalies correlated with negative screening for germline mutations (11 sporadic) in all cases. All patients with confirmed familial disease showed normal underlying venous angioarchitecture. Additionally, a very unusual case of a probable somatic mutation is presented. CONCLUSIONS The SWI results of the venous angioarchitecture of multiple CCMs correlate with sporadic or familial disease. These results are consistent with the theory that venous anomalies are causative for the sporadic form of multiple CCMs.

    A 14-year-old girl was referred for evaluation of the etiology of Cushing syndrome. During the previous 2 years, she had experienced weight gain, secondary amenorrhea, growth retardation, and back pain. Random serum cortisol level, 24-hour urinary free cortisol excretion, and overnight and low-dose dexamethasone suppression tests suggested Cushing syndrome. Midnight adrenocorticotropic hormone (ACTH) level and high-dose dexamethasone suppression test confirmed Cushing disease. Pituitary magnetic resonance imaging was suspicious for microadenoma. To eliminate ectopic ACTH syndrome, and lateralize the pituitary tumor, inferior petrosal sinus sampling (IPSS) was performed by desmopressin use to stimulate ACTH. Finally, the patient was diagnosed with Cushing disease due to ACTH-secreting pituitary microadenoma, lateralized to the left side; subsequently underwent transsphenoidal surgery. Here we report a case of a 14-year-old girl diagnosed with Cushing disease with a pituitary tumor lateralized by IPSS using desmopressin, which is very rare in pediatric Cushing disease.

    Sphenoid sinusitis is unusual in children, but when it occurs, it can lead to serious intracranial complications. We show the value of MRI in demonstrating intracranial abnormalities due to sphenoid sinus infection, particularly those involving the internal carotid arteries and cavernous sinuses. We reviewed our imaging experience of sphenoid sinusitis and found four patients with ICA narrowing who had undergone MR evaluation including conventional and diffusion imaging. MR angiography was also performed in three patients to determine the extent of ICA narrowing. Narrowing of ICA was found in the cavernous segment in all patients and in the supraclinoid segment in three. Cerebral infarction was found in two patients. In one patient the cavernous sinus showed hyperintensity on diffusion-weighted images and hypointensity on apparent diffusion coefficient map, suggesting reduced diffusion. Although infrequent in children, sphenoid sinus infection should be considered as a possible cause of intracranial infection, particularly in teenagers. Early recognition of cavernous sinus involvement and ICA narrowing may lead to prompt treatment and hence a more favorable outcome. (orig.)

    Quantitative susceptibility mapping has been shown to assess iron content in cerebral cavernous malformations. In this study, our aim was to correlate lesional iron deposition assessed by quantitative susceptibility mapping with clinical and disease features in patients with cerebral cavernous malformations. Patients underwent routine clinical scans in addition to quantitative susceptibility mapping on 3T systems. Data from 105 patients met the inclusion criteria. Cerebral cavernous malformation lesions identified on susceptibility maps were cross-verified by T2-weighted images and differentiated on the basis of prior overt hemorrhage. Mean susceptibility per cerebral cavernous malformation lesion (χ̄lesion) was measured to correlate with lesion volume, age at scanning, and hemorrhagic history. Temporal rates of change in χ̄lesion were evaluated in 33 patients. Average χ̄lesion per patient was positively correlated with patient age at scanning (P cavernous malformation lesions with prior overt hemorrhages exhibited higher χ̄lesion than those without (P cavernous malformation lesions, higher mean quantitative susceptibility mapping signal in hemorrhagic lesions, and minimum longitudinal quantitative susceptibility mapping signal change in clinically stable lesions. Quantitative susceptibility mapping has the potential to be a novel imaging biomarker supplementing conventional imaging in cerebral cavernous malformations. The clinical significance of such measures merits further study. © 2016 by American Journal of Neuroradiology.

    Chronic sinusitis is a burdensome disease that has substantial individual and societal impact. Although great advances in medical and surgical therapies have been made, some patients continue to have recalcitrant infections. Microbial biofilms have been implicated as a cause of recalcitrant chronic sinusitis, and recent studies have tried to better understand the pathogenesis of chronic sinusitis as it relates to microbial biofilms. Here, we provide an overview of biofilms in chronic sinusitis with emphasis on pathogenesis, treatment, and future directions. In addition, recent evidence is presented, elucidating the role of bitter taste receptors as a possible key factor leading to biofilm formation.

    2007-01-01

    Thrombophlebitis of dura venous sinuses is a rare intracranial complication of otitis media, which may be sometimes accompanied by symptoms or sepsis. Anatomical conditions and early diagnosis of this vascular complication determine the treatment modality. Aim of this study was the assessment of diagnostics and treatment of venous sinuses thrombophlebitis in acute and chronic otitis media considering anatomy and the venous sinuses and status of coagulation system. Otogenic thrombophlebitis may occur in lateral, transverse, upper and lower petrosal sinuses, and rarely in cavernous. In some cases thrombophlebitis proces may expand into brain or emissary mastoid veins. Lateral sinus thrombophlebitis in chronic otitis media usually appears clinically as septic fever, earache, and increasing neurologic signs. In acute otitis media when thrombophlebitis develops the patient complains about headache, high fever and visual acquity. Diagnosis of venous sinus thrombophlebitis is based on clinical signs, radiological imaging (CT scan, MRI), bacteriological examinations and laboratory biochemical tests. Contrast enhanced CT scan shows "delta sign". Septic thrombophlebitis sinus sigmoidei is caused by mixed bacterial flora. Surgical treatment in cases with septic thrombus consists of radical modiffied ear operation and lateral sinus exposure. Thrombectomy and jugular vein ligation is performed when sepsis or thrombus is present. Mastoidectomy and tympanic cavity drainage is performed in cases with lateral sinus thrombosis in acute mastoiditis. Intravenous antibiotics therapy should be continued for 2 weeks. Anticoagulants should be given taking into consideration parameters of coagulation system and the type of thrombus. Treatment results of venous sinuses thrombophlebitis are good if they are not accompanied by other intracranial complications.

    2016-01-01

    Acute invasive fungal sinusitis is the most aggressive form of fungal sinusitis and can be fatal, especially in patients who are immunosuppressed. Early diagnosis and intervention are crucial and potentially lifesaving, so primary care providers must maintain a high index of suspicion for this disease. Patients may need to be admitted to the hospital for IV antifungal therapy and surgical debridement.

    We assessed the morphological and radiological characteristics of ethmomaxillary sinus (EMS), which is an enlarged posterior ethmoidal air cell occupying the superior portion of the maxillary sinus while draining into superior meatus. This study is based on 1450 patients submitted to CT examination of the paranasal sinuses between 1998 and 2002. Sequential CT scans were obtained in the coronal plane in all the patients with 2.5- to 5-mm section thickness and were evaluated for EMS. The diagnosis of EMS was made when there was a posterior ethmoidal cell occupying the superior part of the maxillary sinus while draining to the superior meatus. When EMS was diagnosed, the morphology of the septum between the and maxillary sinus, and width of the superior meatus, were noted. The EMS was found in 10 of 1450 (0.7%) patients. The coexisting anatomic variations were concha bullosa (50%), upper concha pneumatization (20%), maxillary sinus hypoplasia (20%), uncinate bulla (10%), hypertrophied inferior concha (10%), paradoxic middle concha (10%), and septate maxillary sinus (10%). There was no relation between EMS and sinus disease. The EMS is a rare anatomic variation and does not appear to be associated with sinusitis. The EMS is not a well-studied anatomic variation, and the literature is lacking adequate information about this anatomic variation. This study performed in a large series of patients will possibly contribute to better understanding of this particular anomaly. (orig.)

    A 52-year-old Japanese woman was admitted to our hospital with the renal pelvic mass lesion detected on a health screening examination. The surgical specimen contained a mass exhibiting the histological features of immunoglobulin (Ig)G4-related disease, including lymphoplasmacytic infiltration and sclerosis with numerous IgG4-producing plasma cells. Postoperatively, an elevation of the serum IgG4 level was confirmed at 403 mg/dL; however, there was no evidence of tubulointerstitial nephritis or glomerulopathy, including membranous nephropathy, and the urothelium of the renal pelvis was intact without inflammation. We herein report this case in which IgG4-related disease of the renal pelvic region presented with a mass lesion in the intrarenal sinus near the renal pelvis, not 'pyelitis' (as described by Stone).

    2007-07-01

    Full Text Available Introduction & Objective: Because of widespread use of Functional Endoscopic Sinus Surgery (FESS technique and basic role of coronal CT- Scan in understanding of normal drainage route of Para-nasal sinuses, identifying the major patterns of inflammatory sinonasal disease and accompanied anatomical variations is crucial for appropriate preoperative surgical planning. The purpose of this study was to determine the incidence of major inflammatory patterns and accompanied anatomical variations in patients with chronic inflammatory sinonasal disease that underwent FESS in different hospitals of Hamadan during 2000- 2004.Materials & Methods: This prospective descriptive study was carried out on coronal CT- Scans of 385 patients with chronic inflammatory sinonasal disease that underwent FESS. Patients with clinical signs of chromic rhinosinusitis were diagnosed by otolaryngologist and after 3- 6 weeks of medical therapy if appropriate clinical response were not achieved, coronal and if needed axial CT-Scan were taken from them. CT-Scans were taken mainly in bone and intermediate windows and if soft tissue masses except than polyposis were suspected soft tissue windows were taken too. CT-Scans were reported by radiologist and inflammatory patterns and accompanied anatomical variations with clinical and demographic information were analyzed. Results: In 385 cases major inflammatory pattern included: infundibular 11.1%, osteomeatal unit 37.6%, sphenoethmidal recess 21.2%, sinonasal polyposis 18.9% and sporadic 24.4% . These patterns were seen solely or as a combinations and so total percent was more than 100%. Three major obstructive patterns were seen in 70.1% of cases. In 73.2% of cases accompanied anatomical variation including septal deviation (50.6%, concha bullosa (28.5%, extensive pneumatization of sphenoid sinus (17.9%, paradoxic middle turbinate (16.1%, Haller cell (15.5%, giant bulla ethmoidalis (10.3%, athelectatic uncinate process (8.8%, Agger

    To evaluate the therapeutic effect of gamma knife on patients with intracranial cavernous angioma (CA). The medical records of 122 patients (134 lesions) who underwent radiosurgery were reviewed retrospectively. Th e average follow-up period was 43 months. No patient died. One patient underwent CA resection. In patients with epilepsy, 83% patients showed alleviation of seizures. About 44% of the lesions shrank in size after treatment with gamma knife radiosurgery (59/134). Seven cases had hemorrhage again after radiosurgery, and the overall annual hemorrhage rate was 1.6%. Edema was found in 11.5% patients (14/122) and all patients showed improvement aft er treatment. Gamma knife is a safe treatment for CA, which could obviously improve the symptoms of epilepsy. Gamma knife radiosurgery is the fi rst option for the treatment of cavernous sinus angiomas.

    Single lead atrial (AAI(R)) pacing for sick sinus syndrome provides physiological pacing and is less expensive than a dual chamber system. Compared with ventricular-based pacing, it maintains the normal cardiac depolarization sequence, is associated with less atrial fibrillation and heart failure, and avoids pacemaker syndrome. We sought whether it is possible to select patients for AAI(R) pacing with a low likelihood of subsequent ventricular pacing, and whether this approach was cost-effective. A retrospective review was conducted of AAI(R) pacemaker implantations. Patients requiring a further procedure for insertion of a ventricular lead (for DDD(R) or VVI(R) pacing) were compared with those who remained atrially paced. 2.7% (117 of 4,366) of implants were AAI(R), compared with less than 1% overall for New Zealand and Australia. During follow-up of 3.5 (2.3, 7.7) years, insertion of a ventricular lead was required in 14 (12%), and was more likely in those with pre-existing PR interval >0.20 seconds (odds ratio 7.8, P = 0.003) or left bundle branch block (LBBB, odds ratio 17, P = 0.037). Right bundle branch block, left anterior fascicular block, or history of paroxysmal atrial fibrillation were not more frequent in the group requiring ventricular pacing, and preimplantation Wenckebach point was not different. The most efficient strategy was initial AAIR implantation in all except those with LBBB or PR interval >0.20 seconds. Compared with routine DDDR implantation, cost was reduced by 20%, with a 1.4% annual incidence of further procedures. AAIR is the appropriate pacing choice for sick sinus syndrome without LBBB or PR interval >0.20 seconds.

  3. Brainstem and cerebellar cavernous malformations.

    2017-01-01

    Cavernous malformations are vascular lesions that occur throughout the central nervous system, most commonly in the supratentorial location, with brainstem and cerebellar cavernous malformations occurring more rarely. Cavernous malformations are associated with developmental venous anomalies that occur sporadically or in familial form. Patients with a cavernous malformation can present with headaches, seizures, sensorimotor disturbances, or focal neurologic deficits based on the anatomic location of the lesion. Patients with infratentorial lesions present more commonly with a focal neurologic deficit. Cavernous malformations are increasingly discovered incidentally due to the increasing use of magnetic resonance imaging. Understanding the natural history of these lesions is essential to their management. Observation and surgical resection are both reasonable options in the treatment of patients with these lesions. The clinical presentation of the patient, the location of the lesion, and the surgical risk assessment all play critical roles in management decision-making. © 2017 Elsevier B.V.

    Full Text Available ABSTRACT INTRODUCTION: The proximity of the roots to the maxillary sinus can create a variety of risks. OBJECTIVE: To evaluate the relationship between the roots of healthy teeth and the maxillary sinus, as well as the occurrence of sinus pathologies. METHODS: Three radiologists analyzed 109 cone beam computed tomography (CBCT images. The Kappa test was used to assess the intra- and inter-rater agreement. The chi-squared test and prevalence ratio were used to test the hypothesis that roots of healthy teeth in the maxillary sinus favored the occurrence of sinus pathologies ( p = 0.01. RESULTS: Intra- and inter-rater agreement ranged from good to excellent. The chi-squared test demonstrated a statistically significant difference ( p = 0.006 between the tooth roots in diseased maxillary sinuses (6.09% and those in normal sinuses (3.43%. The prevalence ratio test showed a statistically significant higher prevalence of tooth roots in diseased sinuses than in normal sinuses ( p < 0.0001. Roots in the maxillary sinus were 1.82 times more associated with diseased sinuses. CONCLUSION: Dental roots in the maxillary sinus are almost twice as likely to be associated with diseased sinuses than normal sinuses. Healthy teeth whose roots are inside the maxillary sinus may induce an inflammatory response in the sinus membrane. It is suspected that dental procedures may exacerbate the condition.

    2008-01-01

    Introduction Acute sinusitis is defined pathologically, by transient inflammation of the mucosal lining of the paranasal sinuses lasting less than 4 weeks. Clinically, it is characterised by nasal congestion, rhinorrhoea, facial pain, hyposmia, sneezing, and, if more severe, additional malaise and fever. It affects 1−5% of the adult population each year in Europe. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments in people with clinically diagnosed acute sinusitis, and with radiologically or bacteriologically confirmed acute sinusitis? We searched: Medline, Embase, The Cochrane Library and other important databases up to August 2007 (BMJ Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 19 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics (amoxicillin, co-amoxiclav, doxycycline, cephalosporins, macrolides, different doses [amoxicillin, co-amoxiclav, doxycycline, cephalosporins, macrolides], long-course regimens), antihistamines, cephalosporins or macrolides, decongestants (xylometazoline, phenylephrine, pseudoephedrine), doxycycline, saline nasal washes, steam inhalation, and topical corticosteroids (intra-nasal).

    Full Text Available A 35-year-old man was admitted because of a 2-year history of nasal obstrction, a nasopharyngeal mass, malaise, and massive cervical lymphadenopathy. Nasal symptoms and nasopharygeal mass were due to rhinoscleroma that was confirmed by an incisional biopsy and culture. The patient underwent cervical lymph node biopsy and culture. The patient underwent cervical lymph node biopsy that revealed the tissue compatible with Rosai-Dorfman disease, also called sinus histiocytosis with massive lymphadenopathy. Rhinoscleroma was treated by a combination of excision and antibiotics. Culture became negative for Klebsiella rhinoscleromatis. Then prednisolone administered for one month and gradually tapered. Lymph nodes became small at the end of treatment. Twelve months follow-up showed no evidence of recurrence of both diseases. To the best of our knowledge, this is the first report of association of rhinoscleroma with Rosai-Dorfman disease. Association of these two rare diseases may be due to just a coincidence, or a common immunologic or microbiologic underlying factor

    2016-01-01

    Full Text Available Silent sinus syndrome (SSS is a rare entity that is associated with spontaneous, painless, unilateral enophthalmos and hypoglobus resulting from downward bowing of the orbital floor in the absence of any symptomatic sinonasal disease. The diagnosis is suspected clinically, but it is confirmed radiologically by its characteristic imaging features that include maxillary sinus outlet obstruction, sinus opacification and sinus volume loss caused by inward retraction of the sinus walls. The purpose of this article is to acquaint the reader with the clinical and imaging features of the SSS, along with a brief discussion about its pathogenesis and treatment, which is relatively unknown among oral and maxillofacial radiologists.

  10. Odontogenic sinusitis: an ancient but under-appreciated cause of maxillary sinusitis.

    Science.gov (United States)

    Patel, Nimish A; Ferguson, Berrylin J

    2012-02-01

    For well over 100 years, it has been appreciated that maxillary dental infections can cause sinusitis. This insight has been largely overlooked with the advent of functional endoscopic sinus surgery (ESS) and its emphasis on the osteomeatal complex. We review several recent case series and reviews of odontogenic sinusitis that characterize and discuss emerging diagnostic modalities in odontogenic sinusitis. In recent publications on odontogenic sinusitis, up to 40% of chronic bacterial maxillary sinus infections are attributed to a dental source, which is far higher than the previously reported incidence of 10%. Plain dental films and dental evaluations frequently fail to detect maxillary dental infection that can be causing odontogenic sinusitis. However, sinus computed tomography (CT) or Cone Beam Volumetric CT (CBVCT) are far more successful in identifying dental disease causing sinusitis. The microbial pathogens of odontogenic sinusitis remain unchanged from earlier reviews; however, the clinical findings in odontogenic sinusitis are better described in recent reviews. Successful treatment of odontogenic sinusitis requires management of the odontogenic source and may require concomitant or subsequent sinus surgery. Odontogenic sinusitis is frequently recalcitrant to medical therapy and usually requires treatment of the dental disease. Sometimes dental treatment alone is adequate to resolve the odontogenic sinusitis and sometimes concomitant or subsequent ESS is required. Evaluation of all patients with persistent chronic rhinosinusitis (CRS) should include inspection of the maxillary teeth on CT scan for evidence of periapical lucencies. Unilateral recalcitrant disease associated with foul smelling drainage is especially characteristic of odontogenic sinusitis. High-resolution CT scans and CBVCT can assist in identifying dental disease.

    Full Text Available Cerebral venous sinus (sinovenous thrombosis (CSVT is a rare life-threatening disorder in childhood that is often misdiagnosed. CSVT encompasses cavernous sinus thrombosis, lateral sinus thrombosis, and superior sagittal sinus thrombosis (SSST. We present an adolescent girl who was well until two weeks earlier when she had a throbbing frontal headache and fever with chills; she later had dyspnoea, jaundice, melena stool, multiple seizures, nuchal rigidity, and monoparesis of the right lower limb a day before admission. Urine test for Salmonella typhi Vi antigen was positive, and Widal reaction was significant. Serial cranial computerized tomography scans revealed an expanding hypodense lesion in the parafalcine region consistent with SSST or a parasagittal abscess. Inadvertent left parietal limited craniectomy confirmed SSST. She recovered completely with subsequent conservative management. Beyond neuropsychiatric complications of Typhoid fever, CSVT should be highly considered when focal neurologic deficits are present.

    The objectives of the current experiments were to develop and characterize primary rat nasal epithelial cultures and evaluate their usefulness as a model of cystic fibrosis (CF) sinonasal transepithelial transport and CF transmembrane conductance regulator (CFTR) function. Laboratory in vitro and animal studies. CFTR+/+ and CFTR-/- rat nasal septal epithelia (RNSE) were cultured on semipermeable supports at an air-liquid interface to confluence and full differentiation. Monolayers were mounted in Ussing chambers for pharmacologic manipulation of ion transport and compared to similar filters containing murine (MNSE) and human (HSNE) epithelia. Histology and scanning electron microscopy (SEM) were completed. Real-time polymerase chain reaction of CFTR+/+ RNSE, MNSE, and HSNE was performed to evaluate relative CFTR gene expression. Forskolin-stimulated anion transport (ΔIsc in μA/cm2 ) was significantly greater in epithelia derived from CFTR+/+ when compared to CFTR-/- animals (100.9 ± 3.7 vs. 10.5 ± 0.9; P rats at 4 months. CFTR expression was similar among species. The successful development of the CFTR-/- rat enables improved evaluation of CF sinus disease based on characteristic abnormalities of ion transport. NA.

    Full Text Available Aim. To report a rare case of arteriovenous malformation in temporal lobe presenting as contralateral orbital symptoms mimicking carotid-cavernous fistula. Method. Interventional case report. Results. A 31-year-old Malay gentleman presented with 2-month history of painful progressive exophthalmos of his left eye associated with recurrent headache, diplopia, and reduced vision. Ocular examination revealed congestive nonpulsating 7 mm exophthalmos of the left eye with no restriction of movements in all direction. There was diplopia in left lateral gaze. Left IOP was elevated at 29 mmHg. Left eye retinal vessels were slightly dilated and tortuous. CT scan was performed and showed right temporal arteriovenous malformation with a nidus of 3.8 cm × 2.5 cm with right middle cerebral artery as feeding artery. There was dilated left superior ophthalmic vein of 0.9 mm in diameter with enlarged left cavernous sinus. MRA and carotid angiogram confirmed right temporal arteriovenous malformation with no carotid-cavernous fistula. Most of the intracranial drainage was via left cavernous sinus. His signs and symptoms dramatically improved following successful embolisation, completely resolved after one year. Conclusion. Intracranial arteriovenous malformation is rarely presented with primary ocular presentation. Early intervention would salvage the eyes and prevent patients from more disaster morbidity or fatality commonly due to intracranial haemorrhage.

    Cerebral mycotic or infective aneurysms are a rare complication of infectious illness, and such aneurysms of the intracavernous portion of the internal carotid artery are rare. They have been described as a consequence of cavernous sinus infection in an immunocompromised host, but not previously in a renal transplant recipient. We present such a case with serial MRI showing progression from arterial narrowing to aneurysm formation. Transcranial Doppler sonography of the middle cerebral artery showed distal asymptomatic embolisation from the aneurysm. (orig.)

  1. Anatomical aspects of sinus floor elevations.

    Inadequate bone height in the lateral part of the maxilla forms a contra-indication for implant surgery. This condition can be treated with an internal augmentation of the maxillary sinus floor. This sinus floor elevation, formerly called sinus lifting, consists of a surgical procedure in which a top hinge door in the lateral maxillary sinus wall is prepared and internally rotated to a horizontal position. The new elevated sinus floor, together with the inner maxillary mucosa, will create a space that can be filled with graft material. Sinus lift procedures depend greatly on fragile structures and anatomical variations. The variety of anatomical modalities in shape of the inner aspect of the maxillary sinus defines the surgical approach. Conditions such as sinus floor convolutions, sinus septum, transient mucosa swelling and narrow sinus may form a (usually relative) contra-indication for sinus floor elevation. Absolute contra-indications are maxillary sinus diseases (tumors) and destructive former sinus surgery (like the Caldwell-Luc operation). The lateral sinus wall is usually a thin bone plate, which is easily penetrated with rotating or sharp instruments. The fragile Schneiderian membrane plays an important role for the containment of the bonegraft. The surgical procedure of preparing the trap door and luxating it, together with the preparation of the sinus mucosa, may cause a mucosa tear. Usually, when these perforations are not too large, they will fold together when turning the trap door inward and upward, or they can be glued with a fibrin sealant, or they can be covered with a resorbable membrane. If the perforation is too large, a cortico-spongious block graft can be considered. However, in most cases the sinus floor elevation will be deleted. Perforations may also occur due to irregularities in the sinus floor or even due to immediate contact of sinus mucosa with oral mucosa. Obstruction of the antro-nasal foramen is, due to its high location, not a

    This plain language summary serves as an overview in explaining sinusitis (pronounced sign-you-side-tis). The purpose of this plain language summary is to provide patients with standard language explaining their condition in an easy-to-read format. This summary applies to those 18 years of age or older with sinusitis. The summary is featured as an FAQ (frequently asked question) format. The summary addresses how to manage and treat sinusitis symptoms. Adult sinusitis is often called a sinus infection. A healthcare provider may refer to a sinus infection as rhinosinusitis (pronounced rhi-no-sign-you-side-tis). This includes the nose as well as the sinuses in the name. A sinus infection is the swelling of the sinuses and nasal cavity.The summary is based on the published 2015 "Clinical Practice Guideline: Adult Sinusitis." The evidence-based guideline includes research to support more effective diagnosis and treatment of adult sinus infections. The guideline was developed as a quality improvement opportunity for managing sinus infections by creating clear recommendations to use in medical practice. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    The purpose of this study was to evaluate the computed tomographic (CT) images of the paranasal sinusitis(PNS). The author examined the extent and the recurring patterns of the paranasal sinusitis and some important anatomic landmarks. The author analyzed PNS images retrospectively in 500 patients who visited Chonbuk National University Hospital between January 1996 and December 1997. The most frequently affected sinus was maxillary sinus (82.9%), followed by anterior ethmoid sinus (67.9%), posterior ethmoid sinus (48.9%), frontal sinus (42.0%) and sphenoid sinus (41.4%). The characteristic features of CT images of the sinusitis were sinus opacification (22.4%), mucoperiosteal thickening (34.3%), and polyposis (2.0%). Sinonasal inflammatory diseases were categorized into 5 patterns according to Babbel's classification. They were 1) infundibular (13.0%), 2) ostiomeatal unit (67.4%), 3)sphenoethmoidal recess (13.0%), 4) sinonasal polyposis (9.6%) and 5) unclassifiable patterns (18.0%). The incidences of contact between sinus and optic nerve were as follows ; the incidences of contact with posterior ethmoid sinus, sphenoid sinus, both posterior sinuses were 11.4%, 66.8%, 6.3%, respectively. The incidences of contact between sphenoid sinus and maxillary nerve, vidian nerve, internal carotid artery were 74.5%, 79.2%, 45.1% respectively. The incidences of pneumatization of the posterior ethmoid sinus were as follows; normal 70.6% and overriding type 29.4%. The incidences of sphenoid sinus pneumatization were as follows; normal 56.9% , rudimentary 12.5%, pterygoid recess 22.7%, anterior clinoid recess 2.7%, and both pterygoid and anterior clinoid recess 5.2%. The inflammatory sinonasal diseases were classified into five patterns using the CT of PNS, which was proven to be an excellent imaging modality providing detailed information about mucosal abnormality, pathologic patterns and the proximity of the important structures to the posterior paranasal sinuses.

    We reviewed 11 cases of intramedullary cavernous haemangiomas (IMCH) studied by MRI, to assess its diagnostic value in these lesions. Follow-up MRI was obtained in five patients 7 days-2 years following the initial study. In one case a postoperative examination was obtained. The diagnosis was pathologically proven in ten cases, and supported in the last by a family and personal history of cavernous haemangiomas. A reticulate appearance with areas of mixed signal intensity in both T1- and T2-weighted images was the most common finding. Homogeneous high, low or intermediate signal intensity was each found in one case. Two small lesions gave low signal. A rim of low signal was less common than in cerebral cavernous haemangiomas. In one case, the brain showed more than 20 lesions with the MRI appearances of cavernous haemangiomas. In two of five patients, serial preoperative MRI showed progressive disappearance of high-signal areas on both T1- and T2-weighted images. To find a haemorrhagic intramedullary lesion on MRI is not rare. Although the appearances are not pathognomonic, an IMCH can be suggested. We suggest that the following characteristics may help: (1) a personal and/or family history of cavernous haemangiomas; (2) typical MRI appearances of mixed acute, subacute and chronic haemorrhage; (3) a tendency for signal intensity to decrease on follow-up; (4) normal spinal angiography; and (5) associated brain lesions.

    We have developed a regenerative medicine therapy for the alveolar bone and endoscopic surgery for maxillary sinus lift without bone grafts, in patients experiencing severe periodontal disease with significant absorption of the maxillary alveolar bone, in which more than 10 mm of bone thickness in the maxillary bone was attained, with satisfactory results. The objective of this study was to examine the treatment outcomes of implants that were performed after these therapies. The participants were 36 patients with severe periodontal disease, who cannot be cured with any other treatments except the extirpation of all teeth. The 36 patients are all patients who underwent regenerative treatment of the alveolar bone through tooth replantation and transplantation of the iliac cancellous bone (the bone marrow) as well as endoscopic surgery for maxillary sinus lift from May 2003 to July 2007 in our clinic. A total of 120 implants were placed in these patients when the replanted teeth fell out because of root resorption, and the success rate was examined. The success rates of the implants were 16 of 33 (48%) in the group when surveyed less than 2 years after the surgery and 84 of 87 (96.5%) in the group when surveyed more than 2 years after the surgery. A statistically significant difference was found between the 2 groups (Chi-squared test, P bones in the maxillary sinus floor, augmented through endoscopic surgery for maxillary sinus lift, to attain the thickness and hardness required for implant placement. Therefore, although the implant treatment should be performed later than 2 years after surgery, chewing is possible during this period, with the replanted teeth that were used for regenerative treatment of the alveolar bone. It is believed that this is an extremely effective treatment method to improve the patients' quality of life.

    Full Text Available Ali Guner, Arif Burak Cekic Department of General Surgery, Karadeniz Technical University, Farabi Hospital, Trabzon, Turkey Abstract: Although it is clinically asymptomatic in some cases, pilonidal sinus disease may also present as a complicated disease, characterized by multiple sinus tracts, leading to severe impairment of patient quality of life. Although clinical studies of pilonidal sinus have been conducted for approximately a century, the gold standard for treatment is undefined. The ideal treatment requires a shorter hospital stay, requires less wound care, results in rapid recovery, maintains quality of life, and has low recurrence rates. In this review, we aim to discuss the challenges and possible solutions for the management of pilonidal sinus disease.

    Familial cerebral cavernous malformations, an autosomal dominant disorder, result in excess morbidity and mortality in affected patients. The disorder is most prevalent in the Southwest United States, where the affected families are most often carriers of the CCM1-KRIT1 Common Hispanic Mutation. The brain and spinal cord parenchyma in these individuals is usually affected by multiple cavernous malformations. Previous studies have shown abnormalities of endothelial cell junctions and the blood-brain barrier in cerebral cavernous malformations. Endothelial cell abnormalities have also been described in pathologic studies of white matter hyperintensities. We compared the prevalence of white matter hyperintensities in a population with known familial cerebral cavernous malformations. We examined 191 subjects with familial cerebral cavernous malformations who were enrolled into an institutional review board-approved study. All carry the same Common Hispanic Mutation in the CCM1 gene. Each subject underwent 3T MR imaging, including gradient recalled-echo, SWI, and FLAIR sequences. The number of cavernous malformations and the number of nonhemorrhagic white matter hyperintensities were counted. Subjects older than 60 years of age were excluded due to the high prevalence of white matter lesions in this population, and children younger than 6 were excluded due to potential sedation requirements. Logistic regression analysis was performed to determine the prevalence of abnormal white matter hyperintensities in those with familial cerebral cavernous malformations compared with healthy controls or those with sporadic cerebral cavernous malformation within the familial cerebral cavernous malformations group; it was also performed to evaluate the associations between abnormal white matter hyperintensities and age, sex, headaches, thyroid disease, diabetes, hypertension, hyperlipidemia, seizure history, or modified Rankin Scale score. Familial CCM1 carriers have a higher

    2015-01-01

    Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3–4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

    During preventive otorhinolaryngological examination of 262 workers from the plant for wood planes, subject to a combined effect of unfavourable microclimatic, dust, toxic (in particular formaldehyde) factors, are carried out profound studies of the nose and the cavities around the nose. More than 50% of the complains are of the nose-gullet which decrease with the increase of the length of service, while the objective changes in the mucous membrane of the nose raise high. In 70 (26.7%) of the workers are observed pathological changes, mainly of chronic hypertrophic rhinitis. Of special interest is the comparative high per cent of changed nasal architectonic (16.0%). In 43.5% of the cases with nasal diseases are established changes in the olfactory function (hyposmia I and II rate) of respiratory type. Deviation on behalf of the respiratory, motive and hemodynamic functions of the nose are observed.

    Full Text Available Spontaneous thrombosis of a giant intracranial aneurysm with parent artery occlusion is known. The exact mechanism is however unclear and various theories have been proposed. We present an unusual case of an angiographically documented cervical internal carotid artery (ICA dissection, which led to total occlusion of the ICA distal to the dissected site, with acute cessation of forward blood flow. This resulted in acute upstream thrombosis of the giant cavernous carotid artery aneurysm and an acute cavernous sinus syndrome-like presentation.

    An aberrant sinus anatomy or pathology can influence the sinus lift technique if it is encountered during surgical exposure. The purpose of the present study was to determine the prevalence of sinus disease and variations of normal anatomy among edentulous patients prior to sinus augmentation. 120 patients attending a private surgical practice (53 women and 67 men, with a mean age of 62.02 years, ranging between 34 and 81 years old) for whom treatment was planned for sinus augmentation were evaluated--medical history, radiographic and clinical examinations. Computerized tomograms (CT) and 3D reconstructions from 240 sinuses were analyzed using Dental CT. Abnormalities were diagnosed in 74.2% of cases. Mucosal thickening was the most prevalent abnormality (68.3%), followed by retention cysts (15.8%) and opacification (9.2%). The diagnosed conditions included mucosal thickening, chronic sinusitis, sinus cysts and polyps. The prevalence of one or more septa per sinus was found to be 30%. Males present pathology more often than females (p=.028). No statistical correlation could be found between age and pathology (p>0.05) No significant differences in age or gender between patients with and without sinus septum were found (p>0.05). The results reinforce the importance of thorough history taking and clinical and radiographic assessment prior to performing sinus augmentation, to prevent the probability of complications.

    Orbital complications categorised by Chandler are emergency. They need early diagnosis and agresive treatment. Stage and origin of orbital complications are identified by rhinoendoscopy, ophtalmologic examination and CT of orbite and paranasal sinuses. Periorbital cellulitis and early stage of orbital cellulitis can be treated conservatively with i. v. antibiotics. Monitoring of laboratory parameters and ophtalmologic symptoms is mandatory. Lack of improvement or worsening of symptoms within 24-48 hours and advanced stages of orbital complications are indicated for surgery. The purpose of the study is to evaluate epidemiology, clinical features and management of sinogenic orbital complications. Retrospective data of 8 patients with suspicion of orbital complication admited to hospital from 2008 to 2013 were evaluated. Patients were analyzed in terms of gender, age, CT findings, microbiology, clinical features, stage and treatment. Male and female were afected in rate 1,66:1. Most of patients were young adult in 3rd. and 4th. decade of life (62,5 %). Acute and chronic sinusitis were cause of orbital complication in the same rate. The most common origin of orbital complication was ethmoiditis (62,5 %), than maxillary (25 %) and frontal (12,5 %) sinusitis. Polysinusitis with affection of ethmoidal, maxillary and frontal sinuses (75 %) was usual CT finding. Staphylococcus epidermidis and Staphylococcus aureus were etiological agens in half of cases. Periorbital oedema (100 %), proptosis, chemosis (50 %), diplopia and glaucoma (12,5 %) were observed. Based on examinations, diagnosis of periorbital oedema/preseptal cellulitis was made in 3 (37,5 %), orbital cellulitis in 3 (37,5 %) and subperiosteal abscess in 2 cases (25 %). All patients underwent combined therapy - i. v. antibiotics and surgery within 24 hours. Eradication of disease from ostiomeatal complex (OMC), drainage of affected sinuses and drainage of subperiosteal abscess were done via fuctional endonasal

    For the past decade, interest has been growing in using underground salt caverns for disposing of wastes. The Railroad Commission of Texas has permitted a few caverns for disposal of nonhazardous oil field waste (NOW) and one cavern for disposal of naturally occurring radioactive materials (NORM) from oil field activities. Several salt caverns in Canada have also been permitted for disposal of NOW. In addition, oil and gas agencies in Louisiana and New Mexico are developing cavern disposal regulations. The US Department of Energy (DOE) has funded several studies to evaluate the technical feasibility, legality, economic viability, and risk of disposing of NOW and NORM in caverns. The results of these studies have been disseminated to the scientific and regulatory communities. However, as use of caverns for waste disposal increases, more government and industry representatives and members of the public will become aware of this practice and will need adequate information about how disposal caverns operate and the risks they pose. In anticipation of this need, DOE has fi.mded Argonne National Laboratory to develop a salt cavern public outreach program. Key components of this program are an informational brochure designed for nontechnical persons and a website that provides greater detail on cavern operations and allows downloadable access to the reports on the topic funded by DOE. This paper provides an overview of the public outreach program.

    Mondejar, R; Lucas, M

    2017-10-01

    Cerebral cavernous malformations (CCMs; OMIM 116860) are enlarged vascular cavities without intervening brain parenchyma whose estimated prevalence in the general population is between 0.1% and 0.5%. Familial CCM is an autosomal dominant disease with incomplete clinical and radiological penetrance. Three genes have been linked to development of the lesions: CCM1/KRIT1, CCM2/MGC4607, and CCM3/PDCD10. The aetiological mutation is not detected in a large percentage of cases and new approaches are therefore needed. The aim of this review is to analyse current molecular techniques and the possible mutations or variations which can be detected in a molecular genetics or molecular biology laboratory. Likewise, we will analyse other alternatives that may help detect mutations in those patients showing negative results. A molecular diagnosis of cerebral cavernous malformations should provide at least the copy number variation and sequencing of CCM genes. In addition, appropriate genetic counselling is a crucial source of information and support for patients and their relatives. Copyright © 2015 Sociedad Española de Neurología.

    The purpose of this study is to describe the clinical and histopathological features, management and outcome of a series of patients with simultaneous occurrence of invasive and non-invasive fungal sinusitis (mixed fungal sinusitis). The histopathological records of patients with fungal sinusitis seen over the last 6 years were reviewed. The clinical, histopathological, treatment and follow up details of all cases with mixed fungal sinusitis were noted. Six cases of mixed fungal sinusitis with concurrent occurrence of chronic granulomatous fungal sinusitis and allergic fungal sinusitis (AFS) were seen during the study period. Most (83.3 %) had bilateral disease. All patients had undergone prior endoscopic sinus surgery at least once within the previous 2 years. Histopathological features showed predominance of invasive disease in half the patients. Except for one patient who did not report for follow up, all patients with predominant chronic granulomatous fungal sinusitis received systemic antifungal therapy and inhaled steroids. Those with predominant features of AFS received oral and inhaled steroids. Five patients with mixed fungal sinusitis who had follow up ranging from 6 months to 5 years were disease free following treatment. Mixed fungal sinusitis should be recognized by the surgeon and pathologist as a separate category of fungal sinusitis whose treatment depends on accurate histological diagnosis. A good outcome may be expected with appropriate therapy.

    Conclusion: Angiographic occlusive IPS of CSDAVF may be related to true occlusion of IPS or patent IPS with compartment of the IPS-CS. There is no statistically significant difference in procedural times for these two different fistula anatomies. Transvenous embolization via angiographic occlusive IPS is a safe and effective method to manage CSDAVFs.

    Accumulating evidence supports a role for inflammation in psychiatric illness, and the onset or exacerbation of psychiatric symptoms may follow non-CNS infections. Here, we provide the first detailed description of obsessive-compulsive and related psychiatric symptoms arising concurrently with sinusitis. We reviewed the charts of 150 consecutive patients evaluated in our Pediatric Acute-onset Neuropsychiatric Syndromes clinic for documented sinusitis as defined by the American Academy of Pediatrics guidelines. Sinusitis treatments, sinonasal imaging, and neuropsychiatric symptoms before, during, and after sinusitis onset were noted. Patients were included in the final review if they had a clear diagnosis of isolated sinusitis (without concurrent illness and/or immunodeficiency), and were evaluated during an episode of sinusitis. 10/150 (6.6%) patients had isolated sinusitis at the time of their neuropsychiatric deterioration. Eight patients received antibiotics to treat sinusitis, three of whom also received sinus surgery. Neuropsychiatric symptoms improved in all eight patients concurrent with resolution of sinusitis per parent report and clinician assessment. One patient did not follow through with recommended sinus surgery or antibiotics and her psychiatric symptoms persisted. One patient was lost to follow-up. Improvement of psychiatric symptoms correlated with resolution of sinus disease in this retrospective study. Identification, treatment, and resolution of underlying infections, including sinusitis, may have the potential to change the trajectory of some neuropsychiatric illnesses. Randomized clinical trials are needed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    2001-03-01

    Maxillary sinus hypoplasia is rare, with an estimated prevalence of 1-5%. Out of the CT scans performed in sinusal patients between March 1998 and June 1999, we report on 4 isolated maxillary sinus hypoplasia, 4 maxillary sinus hypoplasia associated to concha bullosa, and 10 isolated conchae bullosas. All cases were evaluated by nasosinusal endoscopy and CT scan. Size, location and uni/bilateral presentation of concha bullosa is correlated to maxillary sinus hypoplasia presence, specially with regards to uncinate process presence, medial or lateral retraction. The pathogenesis of maxillary sinus hypoplasia is reviewed, and its relation to concha bullosa, evaluating how this could explain some cases of the so called chronic maxillary sinus atelectasia, as an acquired and progressive variant of maxillary sinus hypoplasia in adults.

    Full Text Available Cerebral venous system diseases include cerebral venous thrombosis (CVT, venous sinus stenosis, carotid cavernous fistula (CCF, intracranial arteriovenous malformation (AVM and so on. In recent years, due to the rapid development of neuroimaging and interventional technology, more and more cerebral venous system diseases have been timely diagnosed and treated, such as magnetic resonance black-blood thrombus imaging (MRBTI in the diagnosis of CVT, stenting in the treatment of venous sinus stenosis, micro coil plus Onyx glue or covered stents in the treatment of CCF, which allow us to make a deeper recognition of cerebral venous system diseases. Therefore, this paper will introduce the latest diagnosis and treatment of cerebral venous system diseases. DOI: 10.3969/j.issn.1672-6731.2016.11.006

    Chronic sinusitis is one of the most common otolaryngological diagnoses. Allergic fungal sinusitis and eosinophilic mucin rhinosinusitis can easily be misdiagnosed and treated as chronic sinusitis, causing continuing harm. To better identify and characterise these two subgroups of patients, who may suffer from a systemic disease requiring multidisciplinary treatment and prolonged follow up. A retrospective, longitudinal study of all patients diagnosed with allergic fungal sinusitis or eosinophilic mucin rhinosinusitis within one otolaryngology department over a 15-year period. Thirty-four patients were identified, 26 with eosinophilic mucin rhinosinusitis and 8 with allergic fungal sinusitis. Orbital involvement at diagnosis was commoner in allergic fungal sinusitis patients (50 per cent) than eosinophilic mucin rhinosinusitis patients (7.7 per cent; p sinusitis patients. Allergic fungal sinusitis and eosinophilic mucin rhinosinusitis have the same clinical presentation but different clinical courses. The role of fungus and the ability to confirm its presence are still problematic issues, and additional studies are required.

    Work continues in the cathedral-like cavern that will soon contain ATLAS, the largest particle detector of its type in the world. For such a huge detector, an equally giant cavern must be excavated 100 m underground. The roof must be held without any normal rests at the base; instead it will be supported by huge anchors embedded in concrete that will stop the roof from caving in, located in galleries above the cavern.

  1. Effects of cavern depth on surface subsidence and storage loss of oil-filled caverns

    Energy Technology Data Exchange (ETDEWEB)

    Hoffman, E L

    1992-01-01

    Finite element analyses of oil-filled caverns were performed to investigate the effects of cavern depth on surface subsidence and storage loss, a primary performance criteria of SPR caverns. The finite element model used for this study was axisymmetric, approximating an infinite array of caverns spaced at 750 ft. The stratigraphy and cavern size were held constant while the cavern depth was varied between 1500 ft and 3000 ft in 500 ft increments. Thirty year simulations, the design life of the typical SPR cavern, were performed with boundary conditions modeling the oil pressure head applied to the cavern lining. A depth dependent temperature gradient of 0.012{degrees}F/ft was also applied to the model. The calculations were performed using ABAQUS, a general purpose of finite element analysis code. The user-defined subroutine option in ABAQUS was used to enter an elastic secondary creep model which includes temperature dependence. The calculations demonstrated that surface subsidence and storage loss rates increase with increasing depth. At lower depths the difference between the lithostatic stress and the oil pressure is greater. Thus, the effective stresses are greater, resulting in higher creep rates. Furthermore, at greater depths the cavern temperatures are higher which also produce higher creep rates. Together, these factors result in faster closure of the cavern. At the end of the 30 year simulations, a 1500 ft-deep cavern exhibited 4 percent storage loss and 4 ft of subsidence while a 3000 ft-deep cavern exhibited 33 percent storage loss and 44 ft of subsidence. The calculations also demonstrated that surface subsidence is directly related to the amount of storage loss. Deeper caverns exhibit more subsidence because the caverns exhibit more storage loss. However, for a given amount of storage loss, nearly the same magnitude of surface subsidence was exhibited, independent of cavern depth.

    A 42 year old male presents with worsening pain and an increase in thick chronic drainage of the left sinus. Image studies show complete opacification of the left frontal sinus, left sphenoid sinus, and the left maxillary sinus. The patient was taken to the operating room and tissue for microscopic evaluation was obtained. The microscopic findings were classic for allergic fungal sinusitis: areas of alternating mucinous material and inflammatory cell debris and abundant Charcot-Leyden crystals. Cultures were performed and the patient began steroid therapy and desensitization therapy.

    2002-06-15

    THE DIAGNOSIS OF ACUTE BACTERIAL MAXILLARY SINUSITIS: Is based on at least two of three major criteria: sinus pain, unilateral signs, increasingly voluminous and purulent rhinorrhea. Minor criteria can also be retained for diagnosis if they persist for three days. THE NEED FOR ANTIBIOTIC THERAPY: In this diagnostic context is undeniable, similar to the situation after failure of symptomatic treatment or complication. Likewise for unilateral maxillary sinusitis due to homolateral infection of the superior dental archade or for frontal, ethmoidal, or sphemoïdal sinusities. THE MOST FREQUENTLY CAUSAL BACTERIA: Are Streptococcus pneumoniae and Haemophilus influenzae. For first intention treatment generally relies on beta-lactams (amoxicilin/clavulanic acid, second or third generation cephalosporins); pristinamycin may also be useful. Fluoroquinolones active against pneumococci, e.g. levofloxacin, are reserved for cases of sinusitis with risk of complications and for second line treatment after failure in patients with acute maxillary sinusitis. COMPLICATIONS OF SINUSITIS: Can result from anatomic anomalies or from infectious mechanisms such as metastasis of a locoregional infection: peri-orbital cellulitis, orbital cellulitis, thrombophlebitis of the cavernous sinus, extradural, subdural or intracerebral abscess. Three clinical trials are under way to assess efficacy in the treatment of complicated or high risk sinusitis.

    Objective Intubation is a risk factor for nosocomial sinusitis in adult intensive care patients. Sinusitis in intubated adults can be an occult cause of fever. In children nasal intubation may be associated with a greater risk of sinusitis. No pediatric study has determined the incidence of nosocomial sinusitis in the pediatric intensive care unit (PICU) setting. We hypothesized that within a subset of patients who had head CT imaging: (1) the incidence of sinusitis in PICU patients exceeds the incidence in non-PICU patients; (2) the incidence of sinusitis is greater in PICU patients with a tube (nasotracheal, nasogastric, orotracheal, or orogastric); and (3) nasal tubes confer an increased risk for sinusitis compared to oral tubes. Design Retrospective chart review Setting Independent not-for-profit pediatric healthcare system Patients PICU and non-PICU (inpatients hospitalized on medical-surgical wards) patients referred for head CT Interventions None Measurements and Main Results CT images were evaluated for the presence of a tube and sinusitis. Images were scored using the Lund-MacKay (LM) staging system. Sinusitis was defined as a LM score >3.5. 596 patients were studied; 395 (66.3%) PICU. 197 (50%) PICU versus 69 (34.3%) non-PICU patients had sinusitis (p sinusitis versus 88/248 (35.9%) of those without a tube present (p sinusitis based on tube location (p=0.218). Younger age or the presence of a tube increased the probability of sinusitis (p sinus disease had evidence of sinusitis. This finding raises the concern that sinusitis in PICU patients is common and likely should be considered in the differential diagnosis of fever in PICU patients. PMID:21283043

    Dermal sinus tracts are remnants of incomplete neural tube closure. Dermal sinus tracts in the spine range from asymptomatic pits to tracts with significant disease. Congenital spinal dermal sinus tract can produce significant morbidity if not adequately managed. Spinal subdural abscess caused by the spread of an infection within the dermal sinus tract is rare in children. We now described a 3-year-old male who presented with extensive spinal subdural abscess resulting from dermal sinus tract that was low-lying in the sacral area.

  7. Situs inversus, bronchiectasis, and sinusitis and its relation to immotile cilia: history of the diseases and their discoverers - Manes Kartagener and Bjorn Afzelius

    The relationship of Kartagener's syndrome to immobile cilia syndrome is a fascinating merging of clinical observations and basic science in Zurich, Stockholm, and Toronto. In 1933, Manes Kartagener, a Zurich pulmonary physician, reported four patients with the triad of sinusitis, bronchiectasis, and situs inversus. In the following decades, he reviewed reports of hundreds of cases, but the fact that the male patients with the condition never had offspring eluded his notice. In the 1970s, Bjorn Afzelius, a Ph.D. ultrastructuralist from Stockholm, reported cilia immotility in infertile males, some of the cases occurring in families. Half of the cases had Kartagener's triad. The observation of Afzelius was soon applied to children by Jennifer Sturgess, a Ph.D. ultrastructuralist, and her medical colleagues in Toronto. With over 500 MEDLINE references since 1966 on Kartagener's and over 1,000 references on immotile cilia, the causes of the pulmonary infections have become clearer as the patients demonstrate impaired clearance of mucus with resultant sinus and bronchial disease. The cause of the situs inversus remains elusive to this day. It is appropriate to call the condition Kartagener-Afzelius syndrome. (orig.)

    Allergic fungal sinusitis (AFS) is a form of fungal disease that has recently been considered a distinct clinicopathologic entity. Other forms of fungal sinusitis include acute-fulminant (invasive), chronic indolent (invasive) and mycetoma (non-invasive). Objectives were to assess the presentation and to describe the diagnostic techniques for allergic fungal sinusitis in our setup. Descriptive study was conducted in the Department of ENT and Head & Neck Surgery, Khyber Medical College and Khyber Teaching Hospital, Peshawar from January 2002 to April 2008. Twenty-three cases of allergic fungal sinusitis (ASF) were selected for the study. Data like, name, age, sex, address, clinical features, labs (Eosinophil count) and imaging studies (CT and/or MRI) were recorded, including the pre- and postoperative treatment, operative findings and postoperative results, recurrence of disease were also recorded. Surgical procedures were performed on all cases followed by medical treatment. Study revealed that AFS is a disease of younger age, mainly occurring in 2nd & 3rd decade of life, with male to female ratio 1:1.3. Allergic rhinitis (91%) and nasal polyposis (91%) were important associated factors. Nasal obstruction (96%), nasal discharge (91%), post-nasal discharge (87%) and unilateral multi sinus extension were important clinical features. Increased eosinophil count and increased IgE level was found in 78% cases. Histopathological analysis showed fungal hyphae in all cases and aspergillus was predominant organism on culture. Orbital erosion was seen in 78% and skull base erosion was observed in 9%. Recurrence of disease was seen in nine cases. Allergic fungal sinusitis (AFS) is a disease of young immunocompetent adults. Nasal obstruction, nasal discharge, nasal allergy and proptosis were the most common presentations. Initial diagnosis of allergic fungal sinusitis requires high index of suspicion in patients presenting with chronic rhinosinusitis, such cases should be

    Primitive trigeminal artery (PTA) is the most common anomaly of primitive carotid-basilar anastomosis and is associated with cerebrovascular anomalies, such as aneurysm. Large or giant cavernous aneurysm associated with PTA is rare, and the treatment strategies differ in comparison with large or giant aneurysm without PTA. In this article, we report an unusual case of a giant cavernous aneurysm associated with PTA and review treatment strategies for large or giant cavernous aneurysm associated with PTA. A 38-year-old woman suffered from double vision. Magnetic resonance imaging revealed a mass lesion in the left cavernous sinus, and magnetic resonance angiography showed a giant aneurysm at the cavernous portion of the left internal carotid artery, associated with PTA. Coil embolization, distal to the PTA, was scheduled after high-flow bypass on the same day. Computed tomography scan showed no definite infarction after treatment. A 3-dimensional computed tomography showed disappearance of the aneurysm and good patency of bypass and PTA. The patient experienced improvements in symptoms and was discharged without neurologic deficits (modified Rankin Scale 0). The treatment strategy for large or giant cavernous aneurysm associated with PTA is different from strategies used for large or giant cavernous aneurysm without PTA. Simple ligation of internal carotid artery is inadequate because the aneurysm is supplied through the PTA, from the vertebrobasilar system. Furthermore, the treatment strategy has to be revised according to whether the PTA can be occluded. Keeping in mind PTA preservation, an appropriate strategy should be selected.

    A critical intraoperative variable for the return of tumescence following radical prostatectomy is preservation of the cavernous nerves. We developed a nontoxic technique that would allow high resolution, in vivo real-time imaging specifically of the cavernous nerves. The cavernous nerves were labeled by injecting a fluorescent retrograde nerve tracer into the corpus cavernosum of male rats. Nerves were subsequently imaged in vivo using fiberoptic confocal fluorescent microscopy. Initial screening trials were performed to decide on a nerve tracer capable of axonal labeling, optimize injection concentration and characterize retrograde transport time. Toxicity studies included intracavernous pressure monitoring following electrical nerve stimulation, apoptotic staining of injected cavernous tissue and measurement of lipid peroxidation in nerves exposed to laser emissions during imaging. In vivo real-time video sequences of fluorescently labeled cavernous nerves were recorded. The screening trial indicated that the B subunit of cholera toxin conjugated to AlexaFluor 488 (Invitrogen) provided optimal imaging after 9 days of retrograde transport. Toxicity studies showed that maximal intracavernous pressure responses did not differ between labeled and unlabeled nerves (p = 0.9671). Tracer injection did not increase apoptosis in cavernous tissue and laser exposure did not increase lipid peroxidation in nerves. In vivo real-time imaging of the cavernous nerves is possible with no measurable toxicity, allowing the maintenance of erection. This novel imaging modality may allow urologists to identify cavernous nerves during pelvic surgery.

    Patients with the familial form of cerebral cavernous malformations (CCMs) are haploinsufficient for the CCM1, CCM2, or CCM3 gene. Loss of corresponding CCM proteins increases RhoA kinase-mediated endothelial permeability in vitro, and in mouse brains in vivo. A prospective case-controlled observational study investigated whether the brains of human subjects with familial CCM show vascular hyperpermeability by dynamic contrast-enhanced quantitative perfusion magnetic resonance imaging, in comparison with CCM cases without familial disease, and whether lesional or brain vascular permeability correlates with CCM disease activity. Permeability in white matter far (WMF) from lesions was significantly greater in familial than in sporadic cases, but was similar in CCM lesions. Permeability in WMF increased with age in sporadic patients, but not in familial cases. Patients with more aggressive familial CCM disease had greater WMF permeability compared to those with milder disease phenotype, but similar lesion permeability. Subjects receiving statin medications for routine cardiovascular indications had a trend of lower WMF, but not lesion, permeability. This is the first demonstration of brain vascular hyperpermeability in humans with an autosomal dominant disease, as predicted mechanistically. Brain permeability, more than lesion permeability, may serve as a biomarker of CCM disease activity, and help calibrate potential drug therapy.

    Sick sinus syndrome (SSS) is a common indication for pacemaker implantation. Limited information exists on the association of sick sinus syndrome (SSS) with mortality and cardiovascular disease (CVD) in the general population. We studied 19,893 men and women age 45 and older in the Atherosclerosis Risk in Communities (ARIC) study and the Cardiovascular Health Study (CHS), two community-based cohorts, who were without a pacemaker or atrial fibrillation (AF) at baseline. Incident SSS cases were validated by review of medical charts. Incident CVD and mortality were ascertained using standardized protocols. Multivariable Cox models were used to estimate the association of incident SSS with selected outcomes. During a mean follow-up of 17 years, 213 incident SSS events were identified and validated (incidence, 0.6 events per 1,000 person-years). After adjustment for confounders, SSS incidence was associated with increased mortality (hazard ratio [HR] 1.39, 95% confidence interval [CI] 1.14-1.70), coronary heart disease (HR 1.72, 95%CI 1.11-2.66), heart failure (HR 2.87, 95%CI 2.17-3.80), stroke (HR 1.56, 95%CI 0.99-2.46), AF (HR 5.75, 95%CI 4.43-7.46), and pacemaker implantation (HR 53.7, 95%CI 42.9-67.2). After additional adjustment for other incident CVD during follow-up, SSS was no longer associated with increased mortality, coronary heart disease, or stroke, but remained associated with higher risk of heart failure (HR 2.00, 95%CI 1.51-2.66), AF (HR 4.25, 95%CI 3.28-5.51), and pacemaker implantation (HR 25.2, 95%CI 19.8-32.1). Individuals who develop SSS are at increased risk of death and CVD. The mechanisms underlying these associations warrant further investigation.

    Cavernous angiomas of the bone are rare tumors. Skull cavernomas are even less frequent. Most cavernous angiomas of the bone are congenital tumors. In a review of the literature, we found only one case report of de novo generation of a skull cavernous angioma. We present a case of a 25-year-old woman who had experienced a head injury, and 7 years later exhibited a skull tumor at the exact region of the injury. We performed tumor resection and cranioplasty. Follow-up examinations revealed no recurrence or neurological defects. Pathological findings showed a cavernous angioma-like lesion with some atypical details. We finally diagnosed the lesion as a de novo cavernous angioma. Our case suggests that fine injury may result in de novo generation of bone cavernomas.

    Some types of oil and gas production and processing wastes contain naturally occurring radioactive materials (NORM). If NORM is present at concentrations above regulatory levels in oil field waste, the waste requires special disposal practices. The existing disposal options for wastes containing NORM are limited and costly. This paper evaluates the legality, technical feasibility, economics, and human health risk of disposing of NORM-contaminated oil field wastes in salt caverns. Cavern disposal of NORM waste is technically feasible and poses a very low human health risk. From a legal perspective, there are no fatal flaws that would prevent a state regulatory agency from approving cavern disposal of NORM. On the basis of the costs charged by caverns currently used for disposal of nonhazardous oil field waste (NOW), NORM waste disposal caverns could be cost competitive with existing NORM waste disposal methods when regulatory agencies approve the practice.

  16. A 12-year cavern abandonment test

    Full Text Available In 1997-1998, an abandonment test was performed in a 950-m deep, 8000-m3 salt cavern operated by GDF SUEZ at Etrez, France. In this relatively small brine-filled cavern, which had been kept idle for 15 years before the test, thermal equilibrium was reached. A special system was designed to monitor leaks, which proved to be exceedingly small. In these conditions, brine permeation and cavern creep closure are the only factors to play significant roles in pressure evolution. This test strongly suggested that obtaining an equilibrium pressure such that the effects of these two factors were exactly equal would be reached in the long term. Four years later, pressure monitoring in the closed cavern resumed. Pressure evolution during the 2002-2009 period confirmed that cavern brine pressure will remain constant and significantly smaller than geostatic pressure in the long term, precluding any risk of fracturing and brine seepage to the overburden layers.

    The almost simultaneous introduction of nasal endoscopy and CT imaging led to better understanding of normal and pathologic function of the paranasal sinuses. Diagnosis and treatment of many paranasal sius diseases improved considerably. Endoscopy and CT are not concurrential; they are complementary, but they have specific strengths and weaknesses, as well as specific indicatons and consideratons. Staging systems for chronic sinusitis are currently used based on CT findings and response to medical therapy. Functional endoscopic sinus surgery (FESS) has become the standard procedure for most surgical cases of chronic sinusitis. Indications for FESS have enlarged beyond chronic sinus problems and even beyond the borders of the sinuses. Functional endoscopic sinus surgery aims to gain maximal result (restoring normal function) with minimal trauma and morbidity. (orig.)

    It is estimated that in Europe 10% of adults suffer from chronic sinusitis. Chronic sinusitis can be caused by many different diseases that share chronic inflammation of the sinuses as a common symptom. Rhinitis can be caused by stomach acid coming up from the stomach into the esophagus, which successively can result in chronic sinusitis. The current gold standard for diagnosing GERD is--bothersome for the patient--24 h esophageal pH monitoring. This method can be unpleasant for the patients, which makes it less acceptable. Because of that the criteria for symptomatic GERD were made an alternative diagnostic way. We acknowledge that the presence of heartburn and stomach acid coming up from the stomach into the esophagus at least once a week can be diagnosed as symptomatic GERD. The aim of the study is the assessment of the frequency of symptomatic GERD in patients operated because of chronic sinusitis and impact of symptomatic GERD on the follow-up treatment up to 12 months after endoscopic nasal surgery. The authors analysed 144 patients operated at the JUCM Otolaryngological Clinic in Kraków between 2011 and 2013 because of sinusitis. The inclusion criteria were: diagnosed chronic sinusitis, indications for endoscopic sinus surgery, and a written consent for the research. Each patient was examined laryngologically and surveyed. Patients were divided into two groups: with and without symptomatic GERD. We analysed the symptoms in patients treated for sinusitis with or without GERD before, between 3 and 6 as well as in the 12th month after endonasal surgery. Moreover, we analysed the intensity of the global symptoms (expressed in the VAS scale) and separately for each of the 13 symptoms of chronic sinusitis (expressed on a scale 0 - 3). We established that 33 out of the 144 patients (22.9%) qualified for the first survey reported the symptoms of GERD. In the second survey, which was conducted between 3 and 6 month after ESS, 24 out of 119 (20%) people reported the

    Magnetic resonance imaging (MRI) is the modality of choice to identify intracranial or perineural spread from a head and neck primary tumor. Perineural spread is a form of metastatic disease in which primary tumors spread along neural pathways. Orbital cellulitis is a sight-threatening, and potentially life-threatening condition. Urgent imaging is performed to assess the anatomic extent of disease, including postseptal, cavernous sinus, and intracranial involvement, and identify orbital abscesses that require exploration and drainage. MRI is useful in the evaluation of the brachial plexus. Copyright © 2014 Elsevier Inc. All rights reserved.

    The methods used in MR angiography (MRA) can be roughly divided into two groups: time-of-flight methods (TOF methods) which make use of the influx effect of the flow, and the phase-contrast method of Dumoulin, Souza, and their collaborators (PC method), which utilizes phase differences induced by the flow. In this study, the selection of the MRA method was determined by a comparison of the three-dimensional (3-D) PC and the 3-D TOF method in normal and clinical cases. The tool used was SIGNA Advantage (1.5T) made by GE. The 3-D PC method was applied under a pulse sequence generated by gradient-recalled acquisition in the steady state (GRASS); the pulse sequence used for the 3-D TOF method was spoiled GRASS (SPGR) in a total of 28 cases. The following conclusions were reached: the TOF method should be used when aneurysms, arteriovenous malformations (AVM), and moyamoya disease have been diagnosed, and the PC method should be used when AVM and carotid cavernous fistulae (CCF) are to be evaluated in the flow and when CCFs have been diagnosed.

    We report the follow-up of a previously published case (Forlodou et al. Neuroradiology 38:595-597, 1996) of carotido-cavernous fistulas (CCFs) in a patient presenting with type IV Ehlers-Danlos syndrome (EDS 4) that were successfully treated twice by an endovascular approach. Initial treatment with a detachable balloon was in 1994 for a right CCF, and, 8 years later, a left CCF was treated by selective transarterial occlusion of the cavernous sinus with coils. Unfortunately, the patient suffered from a spontaneous post-operative intracranial haemorrhage in the left hemisphere and died. Review of the literature, technical considerations for bilateral CCF and complication are discussed.

    Frosted branch angiitis is a rare, severe condition. It can be either a primary or a secondary condition and is characterized by rapid deterioration of vision and fulminant retinal vasculitis that manifests as diffuse sheathing of retinal vessels, macular edema, papillitis, vitritis and anterior uveitis. We aimed to describe a case of frosted branch angiitis and cerebral venous sinus thrombosis as an initial neuro-Behçet's disease onset. Diagnosis of Behçet's disease was based on the current 2014 International Criteria for Behçet's Disease and the International consensus recommendation criteria for neuro-Behçet's disease. In addition, a literature review using search parameters of "frosted branch angiitis", "Behçet" and "neuro-Behçet" in the PubMed database is presented. A 28-year-old Brazilian pardo woman presented to our hospital with abrupt bilateral vision loss associated with recurrent aphthous oral ulcers 6 months before visual symptom onset. A fundus examination showed bilateral widespread retinal vasculitis with venous and arterial white sheathing, optic disc swelling, macular edema, and retinal hemorrhages, leading to the diagnosis of frosted branch angiitis. An extensive systemic workup for retinal vasculitis was uneventful, except for brain magnetic resonance imaging demonstrating cerebral venous sinus thrombosis and lymphocytic aseptic meningitis. A diagnosis of neuro-Behçet's disease was made, and treatment was started with methylprednisolone therapy 1 g/day for 5 consecutive days, followed by oral mycophenolate mofetil and infliximab 5 mg/kg infusion. The patient's response was rapid, with improvement of visual acuity to hand movement and counting fingers by day 7 and final visual acuity of counting fingers and 20/130. Frosted branch angiitis may be associated with infectious, noninfectious, or idiopathic causes. An extensive workup should be done to exclude systemic vasculitis such as Behçet's disease.

    The rock cavern storage for spent fuel has been assessed to apply in Korea with reviewing the state of the art of the technologies for surface storage and rock cavern storage of spent fuel. The technical feasibility and economic aspects of the rock cavern storage of spent fuel were also analyzed. A considerable area of flat land isolated from the exterior are needed to meet the requirement for the site of the surface storage facilities. It may, however, not be easy to secure such areas in the mountainous region of Korea. Instead, the spent fuel storage facilities constructed in the rock cavern moderate their demands for the suitable site. As a result, the rock cavern storage is a promising alternative for the storage of spent fuel in the aspect of natural and social environments. The rock cavern storage of spent fuel has several advantages compared with the surface storage, and there is no significant difference on the viewpoint of economy between the two alternatives. In addition, no great technical difficulties are present to apply the rock cavern storage technologies to the storage of domestic spent fuel.

    We investigated the autonomic innervation of the penis by using evoked cavernous activity (ECA). We recruited seven men with thoracic spinal cord injury (SCI) and sexual dysfunction, and six men who were scheduled to have pelvic surgery (PS), specifically non-nerve-sparing radical cystoprostatectomy. In the PS patients, ECA was performed both pre- and postoperatively. The left median nerve was electrically stimulated and ECA was recorded with two concentric electromyography needles placed into the right and left cavernous bodies. We simultaneously recorded hand and foot sympathetic skin responses (SSRs) as controls. In the SCI group, all but one patient had reproducible hand SSRs. None of these patients had ECA or foot SSRs. All the PS patients had reproducible ECA and SSRs, both preoperatively and postoperatively. There was no difference in the latency and amplitude measurements of ECA and SSRs in the postoperative compared with that of the pre-operative period (P>0.05). In conclusion, ECA is absent in men with SCI above the sympathetic outflow to the genitalia. In men, after radical pelvic surgery, ECA is preserved, indicating the preservation of sympathetic fibers.

    A 15-year-old boy presented with an extremely rare optochiasmatic cavernous angioma. He was admitted to a special hospital with the complaint of blurred vision persisting for 1 month. Magnetic resonance imaging and biopsy of the lesion were inconclusive. He was admitted to our neurosurgical clinic after worsening of the visual symptoms 9 months later. Repeat magnetic resonance imaging showed optochiasmatic cavernous angioma which had doubled in size. The lesion was removed completely without any problem. Postoperatively his visual complaints remained stable, but had improved after 1 year. Optochiasmatic cavernous malformation should be treated by surgical excision, whereas biopsy is useless and may result in enlargement.

    To objectively evaluate the contents of corpus cavernous tissue in impotent men using an automated novel image analysis system. Thirty-three impotent men and 2 normal potent men (controls) underwent corpus cavernous biopsies. The procedures were performed using a Biopty gun under local anesthesia. The obtained specimens were stained with Masson's trichome technique, and the collagen fiber contents were evaluated by a computerized morphometric analysis method. In addition, we estimated the intraobserver and interobserver reliability of this automated image analysis system. No major complication was noted during or after the biopsies. Of the 33 impotent patients, 3 were diagnosed as having psychogenic, 11 as having arteriogenic, 13 as having venogenic, 1 as having neurogenic, and 5 as having idiopathic impotence. The collagen fiber percentages in the 35 men were as follows: normal potent: 48.2% +/- 1.4%, psychogenic 55.2% +/- 11.6%, arteriogenic 73.2% +/- 4.4%, venogenic 66.5% +/- 4.2%, neurogenic 76.9%, and idiopathic 77.4% +/- 4.2%. Significant differences were found between the normal potent and arteriogenic groups (P image analysis system. This method significantly reduced the amount of variation introduced by the intra-rater reliability of a technician compared with the manual method. The present automated image analysis system is believed to be a reliable, accurate quantitative measurement tool for studies of penile tissue. Cavernous biopsy is a rapid, safe, and representative modality to study penile disease. An increase in cavernous collagen fibers (or corporal fibrosis) is considered an important factor in impaired erectile function.

    The EVOCAV(DS) trial aimed to quantify the paradoxal atrioventricular (AV) conduction time lengthening in sinus node (SD) patients (pts) paced in AAIR-based pacing mode. SD pts, implanted with dual-chamber pacemaker programmed in AAIR-based pacing mode, were randomized in two arms for a 1-month period: the low atrial pacing (LAP; basic rate at 60 bpm, dual sensor with minimal slope) and the high atrial pacing (HAP; basic rate at 70 bpm, dual sensor with optimized slope, overdrive pacing) arm. At 1 month, crossover was performed for an additional 1-month period. AV conduction time, AV block occurrence and AV conduction time adaptation during exercise were ascertained from device memories at each follow-up. Seventy-nine pts participated to the analysis (75 ± 8 years; 32 male; PR = 184 ± 38 ms; bundle branch block n = 12; AF history n = 36; antiarrhythmic treatment n = 53; beta-blockers n = 27; class III/Ic n = 18; both n = 8). The mean AV conduction time was significantly greater during the HAP (275 ± 51 ms) vs. LAP (263 ± 49 ms) period (p AAIR-based pacing in SD pts may induce a significant lengthening of pts' AV conduction time, including frequent abnormal adaptation of AV conduction time during exercise.

    We present the largest reported cohort of carotid cavernous aneurysms (CCA), comparing the neuro-ophthalmic presentation, complications, and outcome with and without endovascular treatment. Retrospective review of 185 patients with 206 CCAs examined between 1980 and 2001 at a tertiary neuro-ophthalmology and neurovascular service. Patients' symptoms and findings at presentation were recorded and compared with those at outcome. The effect of treatment on outcome and on complication rate was analyzed using the chi test, multivariate analysis of covariance, model-selection log-linear analysis, and multinomial logistic regression. Long-term follow-up was available for 189 of 206 CCAs. Seventy-four CCAs underwent treatment (endovascular, 67 [91%]; surgical treatment, 6 [9%]), and 115 were followed for an average of 4 years, two of which required later treatment. Treatment reduced the incidence and severity of pain, even after adjusting for the severity of initial pain (F(1,192 = 9.59, P = 0.002). Treatment did not significantly affect the patient's final diplopia after adjusting for their initial diplopia (F(1, 182 = 2.01, P = 0.158). Statistical examination revealed that the treated group had a higher proportion of neurological and visual complications than people who were not treated (2(2). = 25.26, P = 0.0003). Endovascular treatment of carotid cavernous aneurysms leads to a significantly higher rate of pain resolution compared with untreated patients, even after adjusting for initial pain severity. Diplopia may not resolve after treatment. The results of this study underscore our approach indicating treatment only in cases of debilitating pain, visual loss from compression, or diplopia in primary gaze or in patients with risk factors for major complications such as pre-existing coagulopathy or sphenoid sinus erosion.

Occasionally, treatment of indirect CCFs with conventional endovascular approach through large veins or the inferior petrosal sinus may not be possible.

We describe three such cases of embolization of CCFs through SOV, and their results.Methods: A retrospective case notes review of treated patients over the past 10 years in one tertiary center constituted our methodology.Results: The fistulas in two cases were successfully coiled with complete obviation of symptoms and signs. The third case was complicated due to difficulty in canulating a deeply seated vein and so had to be abandoned and catheterized through contralateral superior petrosal sinus and treated with liquid embolic material Onyx® successfully.Conclusion: In cases where conventional access to the cavernous sinus may not be possible due to local variations of anatomy, multidisciplinary surgical approaches via the SOV provide an alternative route to successfully and safely close a CCF. However, unexpected anatomical variations could also be encountered within the SOV for which the surgeon should be prepared. Keywords: superior ophthalmic vein, treatment

    Several experimental studies have shown osteitis after the onset of sinusitis, supporting the idea that bone involvement could participate in the dissemination and perpetuation of this inflammatory disease. However, procedures commonly performed for the induction of sinusitis, such as antrostomies, can trigger sinusitis by themselves. To evaluate osteitis in an animal model of sinusitis that does not violate the sinus directly and verify whether this is limited to the induction side, or if it affects the contralateral side. Experimental study in which sinusitis was produced by inserting an obstructing sponge into the nasal cavity of 20 rabbits. After defined intervals, the animals were euthanized and maxillary sinus samples were removed for semi-quantitative histological analysis of mucosa and bone. Signs of bone and mucosal inflammation were observed, affecting both the induction and contralateral sides. Statistical analysis showed correlation between the intensity of osteitis on both sides, but not between mucosal and bone inflammation on the same side, supporting the theory that inflammation can spread through bone structures, regardless of mucosal inflammation. This study demonstrated that in an animal model of sinusitis that does not disturb the sinus directly osteitis occurs in the affected sinus and that it also affects the contralateral side.

    Chronic sinusitis is one of the most common presenting complaints of all doctor visits in the United States and Europe, with more than 13% of people affected in any given year. This disease has a wide range of impact on communities. Patients with recurrent or chronic sinusitis report a deteriorative sense of general health and vitality, when compared to general population. In our Department we perform about 600 functional endoscopic sinus surgeries (FESS) per year. Chronic rhinosinusitis represents a spectrum of inflammatory and infectious processes concurrently affecting the nose and paranasal sinuses. Among chronic paranasal sinusitis one must single out paranasal sinusitis with and without polyps. In the paranasal sinusitis patomechanism the blockage of natural ostium plays one of the most important roles. The closure of sinus proper ventilation passages leads to the triggering of many pathological occurrences within mucous membrane of this region. The treatment of paranasal sinusitis is diversified and involves a surgical procedure as well as anti-inflammatory and antiallergic drugs (medications) and mucolytics. Its purpose is to clear the nose through the elimination of bacterial infection, liquidating and removal of lying discharge and the restoration of the proper muco-ciliary transportation, and through this the improvement of local condition and faster recovery. In this work the usage of carboxycysteine to treat paranasal sinus conditions has been presented. Copyright © 2012 Polish Otolaryngology Society. Published by Elsevier Urban & Partner Sp. z.o.o.

    Direct carotid-cavernous fistulas (CCFs) are rare complications of flow diversion and have typically been documented in a subacute time frame after treatment. We present the first reported case of an intraprocedural direct CCF that developed immediately after flow diversion for treatment of a symptomatic paraclinoid right internal carotid artery aneurysm with a neck involving the cavernous segment. Endovascular treatment of such direct fistulas typically involves either transarterial obliteration of the fistulous site or transvenous embolization of the cavernous sinus. Our case was successfully treated with further immediate flow diversion without additional transvenous intervention. There are few reports on the use of flow diversion for treatment of such direct CCFs, and in all but one of these cases, flow diversion was combined with concomitant transvenous embolization. Thus, the presented case is not only the first reported case of an immediate CCF after flow diversion, but it is also only the second reported case of a direct fistula to be successfully treated using solely flow diversion, without additional transvenous intervention. We review the literature of direct CCFs after flow diversion, the pathophysiology of development of CCFs after flow diversion, the literature on treatment of CCFs with flow diversion as well as all other current treatment options. © The Author(s) 2016.

    Cavernous malformation (CM) is a vascular malformation found in the encephalic parenchyma, spinal cord, nerve roots, and extraneural tissue. CM in the trigeminal distribution is exquisitely uncommon and its biological behavior not completely understood. The clinical picture might be diverse, depending on the affected sector of the trigeminal architecture, and literature debating its pathobiology is scarce. We describe a case of 56-year-old woman who presented with left trigeminal neuralgia and a rapidly growing cavernous malformation of the entire distribution of the fifth nerve. The clinical picture evolved to a progressive gait ataxia and follow-up neuroimaging showed a large intracranial mass leading to a brainstem compression. After microsurgical resection, the mass proved to be a typical CM of the trigeminal root. We present an uncommonly aggressive progression of a CM of the trigeminal root, Gasserian ganglion, and cavernous sinus evolving to severe brainstem compression. The documentation of this unique case as well as its management is presented is discussed. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available It has been proved beyond doubt that the causation and perpetuation of disease in the dependent sinuses (maxillary and frontal sinuses is secondary to disease of the ostiomeatal complex, the primary focus of which is the anterior ethmoid. Based on this concept, functional endoscopic sinus surgery (FESS aims at correcting the underlying pathology in the ethmoids and helps to re-establish normal ventilation and mucociliary clearance of the dependent sinuses.

    Cavernous malformations in the pineal region are rare and difficult to anticipate from preoperative evaluation in patients with pineal apoplexy. We herein report the first case of a pineal cavernous malformation with superficial siderosis. Radiological findings were helpful in identifying the presence of the cavernous malformation. A 47-year-old female presented with a 4-month history of progressive headache, nausea, and dizziness. She complained of double vision and exhibited upward gaze palsy and papilledema on fundoscopy. Radiological examination revealed subacute hemorrhage in the pineal region and enlarged lateral ventricles. Furthermore, T2-star-weighted gradient-echo magnetic resonance imaging demonstrated a linear hypointensity along the pial surface of the cerebral cortex, brainstem, and cerebellum, indicating hemosiderin deposition consistent with superficial siderosis. Suspecting the presence of a cavernous malformation based on the radiological findings of superficial siderosis, we performed total mass resection. The postoperative course was uneventful and her preoperative symptoms resolved completely. Radiological findings of superficial siderosis on T2-star-weighted gradient-echo imaging are useful to making a diagnosis of cavernous malformation in cases of pineal apoplexy. They are also important for making the treatment decision to perform total mass resection, which is the best curative method for pineal cavernous malformations. Copyright © 2017 Elsevier Inc.

    Cavernous malformations are low-flow vascular malformations that are histologically characterized by the lack of mural elements of mature vascular structures and intervening parenchymal neural tissue. They are often clinically quiescent, and may grow, bleed, and regress, but can also manifest clinically as neurologic deficits or seizures in the setting of an acute hemorrhage. The low-flow nature of cavernous malformations renders them inherently occult on cerebral angiography. Magnetic resonance imaging has become the mainstay imaging modality in evaluating cavernous malformations, producing characteristic imaging features that usually provide a straightforward diagnosis. Features on magnetic resonance imaging include a reticulated pattern of mixed hyper- and hypointensity on T1- and T2-weighted imaging, with a characteristic hypointense rim best appreciated on T2-weighted imaging or gradient-echo sequences. Contrast enhancement is useful for revealing coexisting developmental venous anomalies that are frequently associated with sporadic cavernous malformations, and may further support the diagnosis. Susceptibility-weighted imaging is highly sensitive for cavernous malformations and accompanying developmental venous anomalies, and is superior to gradient-echo sequences in screening for multifocal, familial cavernous malformations. © 2017 Elsevier B.V.

    We report the case of a 12-month-old girl presenting with diabetes insipidus and Cushing`s disease. Brain magnetic resonance imaging (MRI) demonstrated a large tumour arising from the sella turcica, extending up to the foramen of Monro and invading the cavernous sinuses. Surgery was performed to remove the suprasellar part of the tumour, and histology revealed an adrenocorticotrophin (ACTH) secreting pituitary adenoma. This entity is very rare in this age group and the MRI features have not previously been described. (orig.)

  11. New insights into the pathogenesis of cystic fibrosis sinusitis

    Science.gov (United States)

    2013-01-01

    People with cystic fibrosis (CF) sinus disease have developmental sinus abnormalities with airway bacterial infection, inflammation, impaired mucociliary clearance and thick obstructive mucus. The pathophysiology of airway disease in CF is not completely understood, and current treatments in CF sinus disease ameliorate symptoms but do not provide a cure. This manuscript reviews the history of CF, its manifestations in sinus disease, and the potential impact and relationship of CF on the upper and lower airway. We discuss recent discoveries in the pathophysiology of CF using the CF porcine animal model and exciting treatments that address the primary gene defect that may translate into improved outcomes in CF and non-CF sinusitis in humans.

    2015-01-01

    Full Text Available Autosomal dominant polycystic kidney disease (ADPKD is associated with vascular aneurysms that can affect any part of the vascular tree, like ascending aorta or coronary arteries. Sinus of Valsalva is known as an anatomical dilation at the root of aorta above the aortic valve and very few cases show aneurysm at that site in patients with ADPKD. Sinus of Valsalva aneurysm (SVA can present with rupture and acute heart failure and infective endocarditis or could be asymptomatic accidentally discovered during cardiac catheterization. We report a case of a 76-year-old male with a unique constellation of cardiovascular anomalies associated with ADPKD. Patient was previously diagnosed with aneurysms affecting ascending aorta, sinus of Valsalva, and coronary arteries. Several years later, he came with complete heart block which was discovered later to be secondary to enlargement of his previously diagnosed thrombosed SVA. His case was complicated with acute heart failure and pulmonary edema. Conclusion. Patients with ADPKD can present with extrarenal manifestations. In our case, aneurysm at sinus of Valsalva was progressively enlarging and presented with complete heart block.

    The purpose of this essay is to present a systematic approach to the use of coronal, axial, and sagittal images for CT evaluation of the sinuses before functional endoscopic sinus surgery (FESS). We present a systematic approach to the use of coronal, axial, and sagittal images in CT evaluation before FESS. Each imaging plane is valuable for displaying anatomic variants, which can predispose a patient to recurrent disease and affect the surgical approach, and critical variants, which can make surgery hazardous.

    Streptococcus pneumoniae is a major cause of pneumonia and sinusitis. Pneumonia kills >1 million children annually, and sinusitis is a potentially serious pediatric disease that increases the risk of orbital and intracranial complications. Although pneumococcal conjugate vaccine (PCV) is effective against invasive pneumococcal disease, its effectiveness against pneumonia is less consistent, and its effect on sinusitis is not known. We compared hospitalization rates due to sinusitis, pneumonia, and empyema before and after sequential introduction of PCV7 and PCV13. All children 0 to sinusitis, pneumonia, or empyema in Stockholm County, Sweden, from 2003 to 2012 were included in a population-based study of hospital registry data on hospitalizations due to sinusitis, pneumonia, or empyema. Trend analysis, incidence rates, and rate ratios (RRs) were calculated comparing July 2003 to June 2007 with July 2008 to June 2012, excluding the year of PCV7 introduction. Hospitalizations for sinusitis decreased significantly in children aged 0 to sinusitis and pneumonia in children aged 0 to sinusitis and 19% lower risk of hospitalization for pneumonia in children aged 0 to <2 years, in a comparison of 4 years before and 4 years after vaccine introduction.

    An incidental persistent falcine sinus was detected in an otherwise normal brain on MRI in a 12-year-old girl who underwent imaging after clinical suspicion of acute disseminated encephalomyelitis. The falcine sinus was associated with a hypoplastic posterior third of the superior sagittal sinus and a dominant straight sinus. Generally, atresia or hypoplasia of the straight sinus is associated with a persistent falcine sinus in postnatal life; otherwise, the falcine sinus disappears before birth. We discuss the embryological basis for such an association in this case. (orig.)

    2016-01-01

    A 70-year-old man was admitted to our clinic with a history of rectal bleeding and constipation, his colonoscopy revealed varicosities and bluish nodular lesions of the rectum (Figure 1). Abdominal CT showed multiple nodular lesions beginning from the distal descending colon and extending to the rectum, calcifications suggesting phleboliths were also seen in these lesions. A contrast enhanced pelvic MRI demonstrated multiple tubular lesions showing hyperintensity on T2-weighted images and hypointensity on T1-weighted images, consistent with the affected areas on the CT scan (Figure 2). It was a diffuse cavernous hemangioma, which mostly affects the rectosigmoid colon in the gastrointestinal tract, and can clinically mimic internal hemorrhoids, ulcerative colitis or cancer (1). Gastrointestinal hemangioma is a rare benign vascular neoplasm, and might be associated with a congenital disorder like Osler-Weber-Rendu disease, Maffucci's syndrome, Klippel-Trénaunay syndrome, or the congenital blue rubber bleb nevus syndrome (2). Even though there are different medical treatment options targeting VEGF and FGF-mediated pathways such as bevacizumab and thalidomide, and endoscopic approaches like sclerotherapy and electrocautery; complete resection of the hemangioma is the only curative treatment method (1, 3). Therefore, the patient was referred to department of surgery for a definitive treatment, and lost to follow-up.

    Anomalous coronary arteries originating from the opposite sinus of Valsalva (ACAOS) are associated with adverse cardiac events. Discrimination between ACAOS and coronary artery disease (CAD)-related perfusion defects may be difficult. The aim of the present study was to investigate the value of hybrid coronary computed tomography angiography (CCTA)/SPECT-MPI in patients with ACAOS and possible concomitant CAD. We retrospectively identified 46 patients (mean age 56 ± 12 years) with ACAOS revealed by CCTA who underwent additional SPECT-MPI. ACAOS with an interarterial course were classified as malignant, whereas all other variants were considered benign. CCTA/SPECT-MPI hybrid imaging findings (ischemia or scar) were analyzed according to the territory subtended by an anomalous vessel or a stenotic coronary artery. Twenty-six (57%) patients presented with malignant ACAOS. Myocardial ischemia or scar was found only in patients who had concomitant obstructive CAD in the vessel matching the perfusion defect as evidenced by hybrid CCTA/SPECT imaging. Hybrid CCTA/SPECT-MPI represents a valuable non-invasive tool to discriminate the impact of ACAOS from concomitant CAD on myocardial ischemia. Our results suggest that in a middle-aged population myocardial ischemia due to ACAOS per se may be exceedingly rare and is more likely attributable to concomitant CAD.

    Heart rate variability is an established risk factor for mortality in both healthy dogs and animals with heart failure. The aim of this study was to compare short-term heart rate variability (ST-HRV) parameters from 60-min electrocardiograms in dogs with sick sinus syndrome (SSS, n=20) or chronic mitral valve disease (CMVD, n=20) and healthy controls (n=50), and to verify the clinical application of ST-HRV analysis. The study groups differed significantly in terms of both time - and frequency- domain ST-HRV parameters. In the case of dogs with SSS and healthy controls, particularly evident differences pertained to HRV parameters linked directly to the variability of R-R intervals. Lower values of standard deviation of all R-R intervals (SDNN), standard deviation of the averaged R-R intervals for all 5-min segments (SDANN), mean of the standard deviations of all R-R intervals for all 5-min segments (SDNNI) and percentage of successive R-R intervals >50 ms (pNN50) corresponded to a decrease in parasympathetic regulation of heart rate in dogs with CMVD. These findings imply that ST-HRV may be useful for the identification of dogs with SSS and for detection of dysautonomia in animals with CMVD.

  6. Analysis of cavern stability at the West Hackberry SPR site.

    Ehgartner, Brian L.; Sobolik, Steven Ronald

    2009-05-01

    This report presents computational analyses that simulate the structural response of caverns at the Strategic Petroleum Reserve (SPR) West Hackberry site. The cavern field comprises 22 caverns. Five caverns (6, 7, 8, 9, 11) were acquired from industry and have unusual shapes and a history dating back to 1946. The other 17 caverns (101-117) were leached according to SPR standards in the mid-1980s and have tall cylindrical shapes. The history of the caverns and their shapes are simulated in a three-dimensional geomechanics model of the site that predicts deformations, strains, and stresses. Future leaching scenarios corresponding to oil drawdowns using fresh water are also simulated by increasing the volume of the caverns. Cavern pressures are varied in the model to capture operational practices in the field. The results of the finite element model are interpreted to provide information on the current and future status of subsidence, well integrity, and cavern stability. The most significant results in this report are relevant to Cavern 6. The cavern is shaped like a bowl with a large ceiling span and is in close proximity to Cavern 9. The analyses predict tensile stresses at the edge of the ceiling during repressuization of Cavern 6 following workover conditions. During a workover the cavern is at low pressure to service a well. The wellhead pressures are atmospheric. When the workover is complete, the cavern is repressurized. The resulting elastic stresses are sufficient to cause tension around the edge of the large ceiling span. With time, these stresses relax to a compressive state because of salt creep. However, the potential for salt fracture and propagation exists, particularly towards Cavern 9. With only 200 ft of salt between the caverns, the operational consequences must be examined if the two caverns become connected. A critical time may be during a workover of Cavern 9 in part because of the operational vulnerabilities, but also because dilatant damage is

    Experience with dissection of the cavernous sinus and the temporal bone is essential for training in skull base surgery, but the opportunities for cadaver dissection are very limited. A modification of a commercially available prototype three-dimensional (3D) skull base model, made by a selective laser sintering method and incorporating surface details and inner bony structures such as the inner ear structures and air cells, is proposed to include artificial dura mater, cranial nerves, venous sinuses, and the internal carotid artery for such surgical training. The transpetrosal approach and epidural cavernous sinus surgery (Dolenc's technique) were performed on this modified model using a high speed drill or ultrasonic bone curette under an operating microscope. The model could be dissected in almost the same way as a real cadaver. The modified 3D skull base model provides a good educational tool for training in skull base surgery.

    Dural cavernous haemangiomas are rare, and they do not display a classical ring of haemosiderin on MRI as parenchymal cavernous haemangiomas.

    2017-10-27

    Odontogenic causes of sinusitis are frequently missed; clinicians often overlook odontogenic disease whenever examining individuals with symptomatic rhinosinusitis. Conventional treatments for chronic rhinosinusitis (CRS) will often fail in odontogenic sinusitis. There have been several recent developments in the understanding of mechanisms, diagnosis, and treatment of odontogenic sinusitis, and clinicians should be aware of these advances to best treat this patient population. The majority of odontogenic disease is caused by periodontitis and iatrogenesis. Notably, dental pain or dental hypersensitivity is very commonly absent in odontogenic sinusitis, and symptoms are very similar to those seen in CRS overall. Unilaterality of nasal obstruction and foul nasal drainage are most suggestive of odontogenic sinusitis, but computed tomography is the gold standard for diagnosis. Conventional panoramic radiographs are very poorly suited to rule out odontogenic sinusitis, and cannot be relied on to identify disease. There does not appear to be an optimal sequence of treatment for odontogenic sinusitis; the dental source should be addressed and ESS is frequently also necessary to alleviate symptoms. Odontogenic sinusitis has distinct pathophysiology, diagnostic considerations, microbiology, and treatment strategies whenever compared with chronic rhinosinusitis. Clinicians who can accurately identify odontogenic sources can increase efficacy of medical and surgical treatments and improve patient outcomes.

    Ehgartner, Brian L.; Sobolik, Steven Ronald

    2009-04-01

    This report presents computational analyses that simulate the structural response of caverns at the Strategic Petroleum Reserve Bryan Mound site. The cavern field comprises 20 caverns. Five caverns (1, 2, 4, and 5; 3 was later plugged and abandoned) were acquired from industry and have unusual shapes and a history dating back to 1946. The other 16 caverns (101-116) were leached according to SPR standards in the mid-1980s and have tall cylindrical shapes. The history of the caverns and their shapes are simulated in a 3-D geomechanics model of the site that predicts deformations, strains, and stresses. Future leaching scenarios due to oil drawdowns using fresh water are also simulated by increasing the volume of the caverns. Cavern pressures are varied in the model to capture operational practices in the field. The results of the finite element model are interpreted to provide information on the current and future status of subsidence, well integrity, and cavern stability. The most significant result in this report is relevant to caverns 1, 2, and 5. The caverns have non-cylindrical shapes and have potential regions where the surrounding salt may be damaged during workover procedures. During a workover the normal cavern operating pressure is lowered to service a well. At this point the wellhead pressures are atmospheric. When the workover is complete, the cavern is repressurized. The resulting elastic stresses are sufficient to cause tension and large deviatoric stresses at several locations. With time, these stresses relax to a compressive state due to salt creep. However, the potential for salt damage and fracturing exists. The analyses predict tensile stresses at locations with sharp-edges in the wall geometry, or in the case of cavern 5, in the neck region between the upper and lower lobes of the cavern. The effects do not appear to be large-scale, however, so the only major impact is the potential for stress-induced salt falls in cavern 5, potentially leading to

    2006-07-01

    This report presents computational analyses to determine the structural integrity of different salt cavern shapes. Three characteristic shapes for increasing cavern volumes are evaluated and compared to the baseline shape of a cylindrical cavern. Caverns with enlarged tops, bottoms, and mid-sections are modeled. The results address pillar to diameter ratios of some existing caverns in the system and will represent the final shape of other caverns if they are repeatedly drawn down. This deliverable is performed in support of the U.S. Strategic Petroleum Reserve. Several three-dimensional models using a close-packed arrangement of 19 caverns have been built and analyzed using a simplified symmetry involving a 30-degree wedge portion of the model. This approach has been used previously for West Hackberry (Ehgartner and Sobolik, 2002) and Big Hill (Park et al., 2005) analyses. A stratigraphy based on the Big Hill site has been incorporated into the model. The caverns are modeled without wells and casing to simplify the calculations. These calculations have been made using the power law creep model. The four cavern shapes were evaluated at several different cavern radii against four design factors. These factors included the dilatant damage safety factor in salt, the cavern volume closure, axial well strain in the caprock, and surface subsidence. The relative performance of each of the cavern shapes varies for the different design factors, although it is apparent that the enlarged bottom design provides the worst overall performance. The results of the calculations are put in the context of the history of cavern analyses assuming cylindrical caverns, and how these results affect previous understanding of cavern behavior in a salt dome.

    1988-06-01

    Magnetic resonance imaging (MRI) and CT were performed on 16 lesions of 13 patients with cases of cavernous hemangioma (10 cases of a solitary lesion and 1 case of multiple lesions). Six of the 16 cavernomas were histologically confirmed. All the lesions were detected on enhanced CT scans; fifteen of the 16 lesions were detected on MR images. The cavernous hemangiomas showed various signal intensities on both T/sub 1/-weighted and T/sub 2/-weighted images. All lesions not associated with a fresh hematoma were circumscribed by a curvilinear low-intensity area, most prominently on T/sub 2/-weighted images. This low-intensity band around cavernous hemangiomas on T/sub 2/-weighted images seemed to represent the hemosiderin leiden peritumoral brain.

    Gangliocytic lesions of the pituitary gland producing Cushing's disease are extremely rare entities that may exist with or without a pituitary adenoma. The latter have been designated mixed pituitary adenoma-gangliocytomas, the majority of which produce growth hormone, not adrenocorticotropin (ACTH), and are localized to the anterior gland. We now report an immunocompetent woman with hypercortisolism who presented with an intranasal aspergilloma eroding the bony sellar floor. The fungal ball was contiguous with, and extended into, a large neurohypophyseal-centered mass. Transsphenoidal resection revealed a gangliocytic lesion of the posterior gland with small clusters of intimately admixed ACTH-immunoreactive adenoma cells as the cause of her Cushing's disease. Rare transitional sizes and shapes of cells coupled with immunohistochemical findings supported interpretation as advanced neuronal metaplasia within an ACTH adenoma. This mixed ACTH adenoma-gangliocytoma is the first example to present clinically with an opportunistic infection.

    There are asymmetries in the sizes of transverse sinus and intraocular pressure. The purpose of this study was to investigate possible relationships between the asymmetry of transverse sinuses in TOF MR venography and intraocular pressures of right and left eyes. In this study, subjects were 63 male and 42 female medical school students, aged 18-21 years (mean{+-}SD; 19.72{+-}0.67 years). Subjects with neurological and ophthalmologic disease, particularly dural sinus thrombosis, myopia, trauma and glaucoma, were excluded the study. Subjects were divided into five groups according to the magnitudes of the right- and left-transverse sinuses in MR venography results. There is a functional relation between intraocular pressures of the right and left eyes and asymmetry of the transverse sinus. If the transverse sinus on one side is larger and its venous drainage is greater, the intraocular pressure of the eye on this side is lower. It can be speculated that the transverse sinus size may be associated with pathogenesis of diseases with increased intraocular pressure such as glaucoma. We aim to determine the relation between the size and drainage of transverse sinuses in TOF MR venography and intraocular pressure in patients with open-angle glaucoma in our next study. (orig.)

It is most commonly located in head and neck region, trunk and extremities but very rarely it can be located at clitoris. However, it is very important to differentiate clitoral haemangioma from enlargement of the clitoris secondary to androgen excess. Only four cases of clitoromegaly caused by cavernous haemangioma have been reported in the literature so far. Herein, we report our experience with a 10-year-old girl who presented with clitoromegaly and normal hormonal assay that turned out to be clitoral cavernous haemangioma after histopathological examination of the clitoral mass.

    Paranasal sinus development and pneumatisation variants are described, and rhinosinusitis and different patterns of inflammatory sinonasal diseases are reviewed. Other inflammatory sinonasal diseases, e.g., fungal sinusitis, mucocele, pyocele and sinonasal manifestations in systemic diseases, are briefly described. Computed tomography (CT) is the primary modality in diagnosing and mapping suspected inflammatory sinonasal disease. Magnetic resonance (MR) imaging is complementary to CT if fungal sinusitis, pyocele or malignancy are suspected. (orig.)

    Nasal tuberculosis is very rare but much rarer is tuberculosis of paranasal sinuses. It involves especially the maxillary sinus and is usually unilateral. We report an unusual case of tuberculosis of frontal and maxillary sinus in a 68 years old male, who presented with a swelling above left medial canthus, with no other eye or nasal complaints. Clinical and radiological findings on our initial evaluation suggested that the patient had left frontal mucocoele with bilateral maxillary haziness. Diagnosis was established on FNAC report and subsequent Ziehl - Neelsen staining of nasal swabs and tuberculin skin test. Later chest x-ray examination was suggestive of pulmonary tuberculosis, which was the primary cause. Patient responded well to antituberculosis drug therapy.

    We describe an interactive, intraoperative imaging-guided method for performing endoscopic sinus surgery (ESS) within a vertically open MR system. The procedure was performed with intraoperative imaging using a 0.5-T magnet with a 56-cm vertical gap. Interactive control of imaging planes was accomplished by optical tracking with two infrared light-emitting diodes mounted on an aspirator probe. The probe's position defined the location of the orthogonal imaging planes. Twelve patients with varying degrees of sinus disease underwent ESS with MR imaging guidance. Patients had acute and chronic sinusitis, nasal polyposis causing airway obstruction, or tumor requiring tissue biopsy. All procedures were performed with the patients under general anesthesia. The integration of endoscopy with optical tracking and intraoperative interactive imaging allowed localization of anatomic landmarks during ESS. No complications were encountered.

  1. Maxillary sinus augmentation

    Full Text Available Placing dental implants in the maxillary posterior region can be both challenging and un-nerving for a regular implant dentist who is not well versed with advanced surgical procedures. It is vital for a general dentist to understand the fundamentals of bone grafting the maxillary sinus if he/she is really committed to providing the best health care for their patients. The dental practice is seeing an increasing group of patients who are living longer, and this group of older baby boomers often has an edentulous posterior maxilla either unilateral or bilateral. When edentulous, the posterior maxilla more likely has diminished bone height, which does not allow for the placement of dental implants without creating additional bone. Through grafting the maxillary sinus, bone of ideal quality can be created (allowing for placement of dental implants, which offer many advantages over other tooth replacement modalities. The sinus graft offers the dental patient a predictable procedure of regenerating lost osseous structure in the posterior maxilla. This offers the patient many advantages for long-term success. If dentists understand these concepts, they can better educate their patients and guide them to have the procedure performed. This article outlines bone grafting of the maxillary sinus for the purpose of placing dental implants. This review will help the readers to understand the intricacies of sinus augmentation. They can relate their patient's condition with the available literature and chalk out the best treatment plan for the patient, especially by using indirect sinus augmentation procedures which are less invasive and highly successful if done using prescribed technique.

    Although many options exist for surgical treatment of pilonidal sinus disease (PSD), consensus has not yet been achieved, as all surgical methods have various rates of complications, postoperative infection, and recurrence. This study was a prospective, randomized, clinical trial, and was conducted with consecutive 100 patients admitted to Ankara Military Hospital General Surgery Service for treatment of PSD from May 2013 to August 2013. This study compared two surgical treatments for PSD: modified Limberg flap transposition and lateral advancement flap transposition with Burow's triangle. The patients received surgical treatment with either modified Limberg flap transposition (n = 50) or lateral advancement flap transposition with Burow's triangle (n = 50). Clinical healing period, length of hospital stay, operative time, postoperative complications including recurrence, wound dehiscence, and surgical site infection, as noted during postoperative follow-up period; Visual Analog Scale scores for pain. The mean follow-up period was 12 months. No significant differences were observed between the 2 groups in length of hospital stay (P = .515), operative time (P = .175), wound dehiscence (P = .645), and Visual Analog Scale pain scores (P = .112). The mean operative times were 42.5 minutes in the modified Limberg group and 40.0 minutes in the lateral advancement group. Although lateral advancement flap transposition with Burow's triangle is used less often than modified Limberg flap transposition, we could not determine a parameter that was statistically different such as operative time, postoperative complication, or the length of hospital stay. Hence, the lateral advancement flap is as viable an option as other more preferable techniques in the treatment of PSD, which particularly settled on the upper segment without a deep natal cleft.

    A case report and discussion of cutaneous odontogenic sinus tracts, frequently encountered but often misdiagnosed and mistreated, are presented. Awareness that periapical dental abscesses are the most common etiologic factor of cutaneous sinus tracts involving the face and neck will facilitate their early diagnosis and prevent needless treatment or anxiety for the patient. These lesions are often misinterpreted as chronic, resistant to therapy, pyogenic nodules, or granulomas. A high degree of suspicion is required for making the correct diagnosis, and dental roentgenographic studies should routinely be obtained in all such lesions. Permanent healing cannot be achieved unless the original site of infection is located and eradicated.

  4. Traumatic dural venous sinus thrombosis: A Mini Review

    2016-09-01

    Full Text Available The dural venous sinus thrombosis is a benign disease, representing about 1% of cerebral vascular events. In some cases the development of the disease increased intracranial pressure or symptomatic epilepsy. The development towards a dural venous sinus thrombosis is rare, but is a condition to be considered before the development of ischemic vascular events and a history of recent head trauma. Intracranial hematomas or skull fractures can lead to the establishment of obstructive pathology of the dural venous sinuses. The knowledge of this entity is necessary for the critical care staff and neurosurgery staff.

    Fisher, Oriana S; Boggon, Titus J

    2014-05-01

    Cerebral cavernous malformations (CCM) are neurovascular dysplasias that result in mulberry-shaped lesions predominantly located in brain and spinal tissues. Mutations in three genes are associated with CCM. These genes encode for the proteins KRIT1/CCM1 (krev interaction trapped 1/cerebral cavernous malformations 1), cerebral cavernous malformations 2, osmosensing scaffold for MEKK3 (CCM2/malcavernin/OSM), and cerebral cavernous malformations 3/programmed cell death 10 (CCM3/PDCD10). There have been many significant recent advances in our understanding of the structure and function of these proteins, as well as in their roles in cellular signaling. Here, we provide an update on the current knowledge of the structure of the CCM proteins and their functions within cellular signaling, particularly in cellular adhesion complexes and signaling cascades. We go on to discuss subcellular localization of the CCM proteins, the formation and regulation of the CCM complex signaling platform, and current progress towards targeted therapy for CCM disease. Recent structural studies have begun to shed new light on CCM protein function, and we focus here on how these studies have helped inform the current understanding of these roles and how they may aid future studies into both CCM-related biology and disease mechanisms.

    Full Text Available Background: Imaging abnormalities in the paranasal sinuses are regularly noted as incidental findings on MRI, however, little is known about their prevalence in the Iranian population. The purpose of this study was to classify these findings in the paranasal sinuses as seen on MRI and to investigate the prevalence, according to site and type of paranasal abnormality. Methods: In this cross-sectional study, the T2-weighted axial MRI of 256 patients with diseases unrelated to their paranasal sinuses were reviewed between May 2002 and June 2003. The findings were categorized according to the anatomic location and the imaging characteristics of the abnormality. The abnormalities recorded included total sinus opacification, mucoperiosteal thickening >5mm, air fluid levels and retention cysts or polyps. Unilateral or bilateral involvement and septal deviation were also noted. A sinus was considered normal if it was fully aerated and no soft-tissue density was apparent within the cavity. Results: Among our cases, 111 (43.5% were male and 145 (56.5% were female. Of these patients, abnormalities in one or more of the sinus groups were found in 110 subjects (42.9%, 55.5% of which were male and 44.5% were female (P=0.001. Maxillary sinus abnormalities were observed in 66.4% of the patients, while ethmoid sinus abnormalities were found in 63.6%. Of the ethmoid abnormalities, 21% were found in the anterior section, 9% in the middle ethmoid, and 8% in the posterior ethmoid. The most common abnormality found was mucosal thickening. Among our cases, 23.4% had septal deviation, which was significantly higher among those with sinusitis (29% versus 19.1%; P<0.01. Of those patients with sinus involvement, 16% were involved in the sphenoid sinus and 5% in the frontal sinus. The results obtained from the patients with sinus abnormality revealed that 85% suffered from cough, nasal obstruction, runny nose, facial pain and post nasal discharge and 24% had been diagnosed

    ATLAS has been host to many important visitors lately. Here are a selected few: Professor Stephen Hawking visits the ATLAS cavern On Tuesday 26 September 2006 the ATLAS Collaboration was honoured by a very special visit to the detector in the underground cavern. We were pleased to guide Professor Stephen Hawking, the famous cosmologist holding the post of Lucasian Professor of Mathematics at Cambridge University (position held by Isaac Newton in the 17th century), on a tour of the ATLAS pit and the LHC tunnel. The visit was accompanied by a few colleagues from the CERN Theory group, and was only possible thanks to the professional assistance of Olga Beltramello and Bernard Lebegue, who had also taken care of all the necessary preparatory work in the cavern. Professor Hawking was very keen to check for himself the status of the detector installation, and he admired, in particular, the spectacular TGC big wheel on side C.

    The aim of this clinical investigation was to evaluate the clinical and radiologic outcomes of a single-step surgical procedure that includes functional endoscopic sinus surgery (FESS) and maxillary sinus elevation by the lateral window approach in patients with reversible contraindications to sinus elevation. Thirty-eight patients with insufficient bone height in the posterior maxilla caused by pneumatization of the sinus and with reversible ear-nose-throat (ENT) contraindications to sinus elevation were recruited for this investigation between January 2010 and January 2012. All patients were treated in a single session under general anesthesia for a total of 69 consecutive sinus augmentations. FESS was performed by an ENT specialist, and an oral surgeon carried out sinus elevation through the lateral window approach. Particulate xenograft was used beneath the sinus membrane. Intraoperative and postoperative complications (eg, membrane tears, rhinosinusitis, graft infection or loss) were reported. Nasal endoscopies were performed at 7, 14, and 30 days and 3 months after treatment. After a healing period of 6 months, 137 implants were inserted. Computed tomography scans were performed after 6 months and 1 year. Intraoperative membrane perforation occurred in only one case. No implant failures were recorded during the follow-up period. Radiologic and clinical findings showed the resolution of ENT disease and good bone graft integration after 1 year. A relapse of mucosal thickening observed in some patients did not influence the graft healing. Preliminary rhinosinusal evaluation by an ENT specialist and computed tomography of the ostiomeatal complex are necessary in patients needing maxillary sinus elevation. A single-step approach to FESS and sinus elevation is a predictable technique to manage patients with ENT reversible contraindications to sinus elevation.

    Symptomatic cavernous malformations involving the brainstem are difficult to access by conventional approaches, which often require dramatic brain retraction to gain adequate operative corridor. Here, we present a successful endoscopic endonasal transclival approach for resection of a hemorrhagic, symptomatic mesencephalic cavernous malformation. A 20-year-old woman presented with acute onset of headache, nausea, and vomiting. Computed tomography scan revealed a ventral midbrain hemorrhage. On day 3 of admission, the patient developed left-sided hemiparesis, restriction of medial and lateral left-eye movements, and loss of left pupillary light reflex. Subsequent magnetic resonance imaging demonstrated an increase of the midbrain lesion to 1.2 cm × 1.7 cm. Diffusion tensor imaging showed compression and lateral displacement of the right corticospinal tract near the thalamus and cerebral peduncle. Given the patient's clinical presentation and the findings on imaging, we suspected a mesencephalic cavernous malformation. The patient underwent an endoscopic endonasal transclival resection of a ventral midline mesencephalon cavernous malformation. A dark red lesion was directly visualized under the endoscope. After a small cortiectomy, the pial and perforator vessels were dissected, and dark-brown blood was drained from the cavernoma cavity. Using a biopsy forceps and with careful attention to the cavernoma borders, the lesion was removed and hemostasis was achieved. Pathologic examination confirmed cavernous malformation. One week after the operation, magnetic resonance imaging demonstrated total resection of the lesion. A 3-month follow-up revealed improved neurologic symptoms with minimal surgical morbidity.

    2014-07-01

    The aortic sinus vortex is a classical flow structure of significant importance to aortic valve dynamics and the initiation and progression of calcific aortic valve disease. We characterize the spatiotemporal characteristics of aortic sinus vortex dynamics in relation to the viscosity of blood analog solution as well as heart rate. High-resolution time-resolved (2 kHz) particle image velocimetry was conducted to capture 2D particle streak videos and 2D instantaneous velocity and streamlines along the sinus midplane using a physiological but rigid aorta model fitted with a porcine bioprosthetic heart valve. Blood analog fluids used include a water-glycerin mixture and saline to elucidate the sensitivity of vortex dynamics to viscosity. Experiments were conducted to record 10 heart beats for each combination of blood analog and heart rate condition. Results show that the topological characteristics of the velocity field vary in timescales as revealed using time bin-averaged vectors and corresponding instantaneous streamlines. There exist small timescale vortices and a large timescale main vortex. A key flow structure observed is the counter vortex at the upstream end of the sinus adjacent to the base (lower half) of the leaflet. The spatiotemporal complexity of vortex dynamics is shown to be profoundly influenced by strong leaflet flutter during systole with a peak frequency of 200 Hz and peak amplitude of 4 mm observed in the saline case. While fluid viscosity influences the length and timescales as well as the introduction of leaflet flutter, heart rate influences the formation of counter vortex at the upstream end of the sinus. Higher heart rates are shown to reduce the strength of the counter vortex that can greatly influence the directionality and strength of shear stresses along the base of the leaflet. This study demonstrates the impact of heart rate and blood analog viscosity on aortic sinus hemodynamics.

    In the period 1983 to 1985, 66 patients presented to six Japanese university hospitals with squamous cell carcinoma of the maxillary sinus. Using self-administered questionnaires, a case-control study was conducted to examine history of nasal diseases, occupational exposures, and other possible risk factors for this disease. For each patient, two controls were selected from the general population, matched to the patient by sex, age (+/- 5 years), and district of residence. A history of chronic sinusitis was associated with a 2.3-fold increase in risk (p = 0.05). A high relative risk was also observed in males with an occupational history of woodworking or joinery, particularly when these jobs involved sanding or lathing practices (RR = 7.5, p = 0.02). No association between cigarette smoking and maxillary sinus cancer was observed in this study and no evidence was found that indoor air pollution in the home is involved in cancer development.

    Chronic sinusitis is universal in cystic fibrosis (CF) and our current treatments are ineffective in reversing sinus disease. The objective of this work was to determine if increasing CF transmembrane conductance regulator (CFTR) activity by ivacaftor could treat CF sinus disease and assess its effect on primary sinus epithelial cultures. Case report of 1 patient with long-standing chronic sinus disease and a new diagnosis of CF with a mild mutation (P205S) and a severe mutation (G551D). We discuss clinical changes in symptoms, radiographic findings, nasal potential difference testing, and nasal pH values before and after treatment with ivacaftor. We then developed primary sinonasal epithelial cell cultures from a biopsy of the patient to determine changes in airway surface liquid (ASL) pH and ASL viscosity after ivacaftor treatment. Ivacaftor treatment reversed CT findings of CF sinus disease, increased nasal voltage and pH, and resolved sinus symptoms after 10 months of therapy. Ivacaftor significantly increased ASL pH and decreased ASL viscosity in primary airway cultures. This report documents the reversal of CF sinus disease. Based on our in vivo and in vitro results, we speculate that ivacaftor may reverse CF sinusitis by increasing ASL pH and decreasing ASL viscosity. These studies suggest that CFTR modulation may be effective in treating CF and perhaps non-CF sinusitis. © 2014 ARS-AAOA, LLC.

    Cerebral cavernous malformations are vascular anomalies of the central nervous system characterized by clusters of enlarged, leaky capillaries. They are caused by loss-of-function mutations in KRIT1, CCM2, or PDCD10. The proteins encoded by these genes are involved in four partially interconnected signaling pathways that control angiogenesis and endothelial permeability. Cerebral cavernous malformations can occur sporadically, or as a familial autosomal dominant disorder (FCCM) with incomplete clinical and neuroradiological penetrance and great inter-individual variability. Although the clinical course is unpredictable, symptoms typically present during adult life and include headaches, focal neurological deficits, seizures, and potentially fatal stroke. In addition to neural lesions, extraneural cavernous malformations have been described in familial disease in several tissues, in particular the skin. We here present seven novel FCCM families with neurologic and cutaneous lesions. We review histopathological and clinical features and provide an update on the pathophysiology of cerebral cavernous malformations and associated cutaneous vascular lesions. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Efficient management of chronic sinusitis remains a great challenge for primary care physicians. Unlike ENT specialists using Computed Tomography scans, they lack an affordable and safe method to accurately screen and monitor sinus diseases in primary care settings. Lack of evidence-based sinusitis management leads to frequent under-treatments and unnecessary over-treatments (i.e. antibiotics). Previously, we reported low-cost optical imaging designs for oral illumination and facial optical imaging setup. It exploits the sensitivity of NIR transmission intensity and their unique patterns to the sinus structures and presence of fluid/mucous-buildup within the sinus cavities. Using the improved NIR system, we have obtained NIR sinus images of 45 subjects with varying degrees of sinusitis symptoms. We made diagnoses of these patients based on two types of evidence: symptoms alone or NIR images along. These diagnostic results were then compared to the gold standard diagnosis using computed tomography through sensitivity and specificity analysis. Our results indicate that diagnosis of mere presence of sinusitis that is, distinguishing between healthy individuals vs. diseased individuals did not improve much when using NIR imaging compared to the diagnosis based on symptoms alone (69% in sensitivity, 75% specificity). However, use of NIR imaging improved the differential diagnosis between mild and severe diseases significantly as the sensitivity improved from 75% for using diagnosis based on symptoms alone up to 95% for using diagnosis based on NIR images. Reported results demonstrate great promise for using NIR imaging system for management of chronic sinusitis patients in primary care settings without resorting to CT.

    The cavernous venous malformation of the orbit, previously called cavernous hemangioma, is the most common primary orbital lesion of adults. Cavernous venous malformation occurs more often in women and typically presents in the fourth and fifth decades of life. It is a benign vascular malformation characterized by a well-defined capsule and numerous large vascular channels. The most common sign of cavernous venous malformation is progressive axial proptosis from the preferential involvement of the intraconal orbital space. Optic nerve damage and other signs of orbital pathology may be present, with a variable degree of visual impairment. The combination of ultrasound, computed tomography, and magnetic resonance imaging leads to an accurate diagnosis in the vast majority of cases. Surgical and nonsurgical treatments are required in case of symptomatic lesions, with a characteristic multidisciplinary management influencing optimal outcome. Orbitotomy represents the traditional surgical approach. Recently, the endoscopic transnasal approach to the orbital cavity has gained interest, representing a feasible and safe, less-invasive surgical technique for the management of cavernous venous malformation.

    Full Text Available Cavernous angiomas are cerebral cavernous malformations and they are relatively rare lesions. Two forms of cavernous angiomas have been described: a sporadic form, in which patients usually have a single lesion, and a familial form, the hallmarks of which are multiple lesions and autosomal dominant transmission. The familial form appears to be very uncommon and has mainly been described in the Hispanic population. We report two cases of multiple intracranial cavernous angiomas which is an autosomal dominant pattern of inheritance. It is very rare to find this in non Hispanic population.

  7. Allowable pillar to diameter ratio for strategic petroleum reserve caverns.

    2011-05-01

    This report compiles 3-D finite element analyses performed to evaluate the stability of Strategic Petroleum Reserve (SPR) caverns over multiple leach cycles. When oil is withdrawn from a cavern in salt using freshwater, the cavern enlarges. As a result, the pillar separating caverns in the SPR fields is reduced over time due to usage of the reserve. The enlarged cavern diameters and smaller pillars reduce underground stability. Advances in geomechanics modeling enable the allowable pillar to diameter ratio (P/D) to be defined. Prior to such modeling capabilities, the allowable P/D was established as 1.78 based on some very limited experience in other cavern fields. While appropriate for 1980, the ratio conservatively limits the allowable number of oil drawdowns and hence limits the overall utility and life of the SPR cavern field. Analyses from all four cavern fields are evaluated along with operating experience gained over the past 30 years to define a new P/D for the reserve. A new ratio of 1.0 is recommended. This ratio is applicable only to existing SPR caverns.

    Intracranial cavernous angiomas are benign vascular malformations and can be divided into intra-axial and extra-axial lesions. Extra-axial cavernous angiomas are relatively rare and usually arise in relation to the dura mater and mimick meningiomas. We report a case of cavernous angioma that occured in the falx cerebri of a 22-yr-old female patient with the special focus on neuroradiologic findings. This is the fourth case of cavernous angioma in the falx cerebri reported in the literature to our knowledge. PMID:17043437

    Cerebral cavernous malformations are relatively rare vascular disorders that may affect any part of the central nervous system. This presentation has been associated with heterozygous mutations in CCM1/KRIT1, CCM2/malcavernin and CCM3/PDCD10. We aimed to investigate the genetic defect underlying multiple cerebral and vertebral cavernous malformations in a multigenerational Italian family. The proband is a 49-year-old man who underwent cerebral MRI in his thirties for persistent haeadache and tingling in his left arm and leg and was diagnosed with multiple supratentorial cavernous angiomas. A right frontal angioma with radiological evidence of a recent bleeding was surgically removed when he was 39 years old and he was thereafter asymptomatic. Magnetic resonance imaging revealed multiple cerebral cavernous malformations in seven members of his familily. Four subjects were asymptomatic. Other family mambers displayed heterogeneous clinical features including seizures and recurrent brain haemorrhages. Sequence analysis in the proband disclosed a novel heterozygous nucleotide substitution (c.263-10A > G) in intron 5 of CCM1. This variant is predicted to create an abnormal acceptor splice site and segregated in affected relatives available for molecular screening. The analysis of CCM1 transcript in proband's lymphocytes confirmed the partial retention of intron 3 resulting in a premature termination codon. Our findings demonstrate that c.263-10A > G mutation is associated with cerebral cavernous malformations. A better knowledge of the disease-associated phenotype may lead to an early diagnosis and to an appropriate clinical surveillance in affected patients.

    A 47-year-old man presented with a rare case of dural cavernous hemangioma of the cerebellar falx incidentally detected as a mass lesion in the posterior cranial fossa. Neurological examination revealed no deficits or physical symptoms. Computed tomography demonstrated a well-demarcated hyperdense mass, with no calcification, in the cerebellar vallecula. Magnetic resonance imaging showed the extra-axial mass as homogeneously isointense on T(1)-weighted images, and hyperintense on T(2)-weighted images, compared to the adjacent cerebellar parenchyma that had no hypointense halo. The cerebellar vermis was slightly compressed ventrally, the adjacent brain parenchyma was not swollen, and there was no evidence of hydrocephalus. The mass and the attached cerebellar falx were homogeneously enhanced by contrast medium. The dural enhancement was considered a dural tail. No other intracranial vascular malformations were found. The preoperative diagnosis was posterior cranial fossa meningioma attached to the cerebellar falx. Median suboccipital craniotomy exposed the reddish mass attached to the cerebellar falx. The arachnoid plane was well preserved. Total en bloc resection was performed with minimal blood loss. The postoperative course was unremarkable. The resected mass had a reddish-brown mulberry appearance, with spongy cross section with multiple blood-filled spaces. Histological examination identified dilated blood-containing channels lined with flattened endothelium and separated by fibrous tissue, but no luminal thrombus or hemorrhage. The histological diagnosis was dural cavernous hemangioma of the cerebellar falx. Preoperative radiosurgery or embolization is recommended for most of the dural cavernous hemangiomas, but surgery for the present dural cavernous hemangioma of the cerebellar falx was performed safely.

    We report two cases with extratemporal cavernous angioma (CA) and coexisting ipsilateral hippocampal sclerosis. Classically dual pathology is defined as the association of hippocampal sclerosis with an extrahippocampal lesion. Subtle changes in hippocampus might be overlooked in the presence of an unequivocal extrahippocampal abnormality. Seizure outcome after epilepsy surgery in cases with dual pathology is less favourable if only one of the lesions is removed. Dual pathology must always be considered in diagnostic imaging of patients with intractable epilepsy and CA. (orig.)

    We describe a case of cardiac cavernous hemangioma with coexisting pulmonary cavernous hemangiomas and hepatic hemangioma. A 35-year-old woman who had previously received a living donor liver transplant to cure giant hepatic hemangioma was seen because of chest pain. A cardiac neoplasm and multiple pulmonary nodules were detected. The tumor was surgically removed, and biopsy specimens were taken from the lung nodules. Histopathologic examination confirmed that both lesions were cavernous hemangiomas. The patient was discharged without adverse events postoperatively. Cardiac hemangioma is an extremely rare entity; the present case is unique for its multiorgan involvement. Suspicion of this entity should be aroused if the imaging manifestation suggests a vascular nature. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    Despite the advent of oral phosphodiesterase-5 inhibitors, curative treatment for erectile dysfunction (ED) remains unavailable. Recently, the link between ED and cardiovascular disease was unveiled and the main etiology of ED was found to be vasculogenic. Therefore, neovascularization is a promising strategy for curing ED. Angiopoietin-1 (Ang1) is an angiogenic growth factor that promotes the generation of stable and functional vasculature. Here, we demonstrate that local delivery of the soluble, stable, and potent Ang1 variant, COMP-Ang1 gene or protein, into the penises of hypercholesterolemic mice increases cavernous angiogenesis, eNOS phosphorylation, and cGMP expression, resulting in full recovery of erectile function and cavernous blood flow up to 8 weeks after treatment. COMP-Ang1-induced promotion of cavernous angiogenesis and erectile function was abolished in Nos3-/- mice and in the presence of the NOS inhibitor, L-NAME. COMP-Ang1 also restored the integrity of endothelial cell-cell junction by down-regulating the expression of histone deacetylase 2 in the penis of hypercholesterolemic mice and in primary cultured mouse cavernous endothelial cells. These findings constitute a new paradigm toward curative treatment of both cavernous angiopathy and ED. PMID:25783805

    A 33-year-old man who had received mediastinal radiation therapy for Hodgkin's disease 12 years earlier developed a symptomatic sick sinus syndrome requiring the implantation of a permanent pacemaker. The sick sinus syndrome and a finding of an occult constrictive pericarditis were considered to be due to the previous mediastinal irradiation. A ventricular pacemaker was chosen because mediastinal radiotherapy also increases the risk of developing atrioventricular conduction defects.

    Full Text Available Background. Thyroidectomy is one of the most frequently performed surgical procedures worldwide. Despite technical advances and high experience of thyroidectomy of specialized centers, it is still burdened by a significant rate of postoperative complications. Among them, the skin sinus formation is an extremely rare postthyroidectomy complication. Here, we first report the incidence of the skin sinus formation after thyroidectomy to identify the causes for skin sinus formation after thyroidectomy and to discuss its prevention and treatment options. Methods. A retrospective analysis was carried out of patients who underwent excision operation of fistula for postthyroidectomy skin sinus formation. Data were retrieved from medical records department of the Affiliated Hospital of Inner Mongolia Medical University. Results. Of the 5,686 patients who underwent thyroid surgery, only 5 patients (0.088% had developed skin sinus formation. All 5 patients successfully underwent complete excision of fistula. Conclusion. Infection, foreign body, thyroid surgery procedure, combined disease, and iatrogenic factors may be related with skin sinus formation after thyroidectomy. To reduce the recurrence of postoperative infections and sinus formation, intra- and postoperative compliance with aseptic processing, intraoperative use absorbable surgical suture/ligature, repeated irrigation and drainage, and postoperative administration of anti-inflammatory treatment are to be followed.

    The sphenoid sinus is the least common site of mucocele of all paranasal sinuses. It is very rare in children, especially in those younger than 12 years when pneumatization of the sphenoid sinus is completed. We report a case of histologically proven sphenoidal mucocele in a 5-year-old child. The child presented with an acute onset of significant visual impairment and headache. His vision gradually improved after trans-nasal sphenoidotomy and drainage of the sinus content with return of complete normal baseline vision after 2 months. (orig.)

    "Headache and fever" is a common presentation to the urgent care and emergency department setting and can have many etiologies. We present a case of a 10-year-old girl who presented with headache and fever and was found to have intracranial extension of sinusitis despite lack of typical sinus or chronic upper respiratory tract infection symptoms. This case illustrates the need in the emergency department or urgent care to keep a broad differential diagnosis for pediatric headache, especially when initial interventions are unsuccessful. We also review the epidemiology of pediatric sinusitis, age at sinus development, and associated intracranial complications.

    Cavernous angiomas of the spinal cord exhibit imaging characteristics that may overlap with those of hemorrhagic ependymoma. In the present study, we aimed to identify specific magnetic resonance imaging (MRI) findings that could be used to differentiate cavernous angioma from hemorrhagic ependymoma, and to evaluate serial MRI changes in cases of cavernous angioma. We retrospectively evaluated MR images of spinal cord tumors collected at our hospital from 2007 to 2015. From this cohort of images, 11 pathologically confirmed cavernous angiomas and 14 pathologically confirmed hemorrhagic ependymomas were compared with respect to the size of the tumor, longitudinal location, axial location, enhancement pattern, syrinx, edema, tumor margin, signal intensity of T2WI, signal intensity of T1WI, and longitudinal spreading of the hemorrhage. Serial MR images of seven spinal cavernous angiomas were reviewed. Small size, eccentric axial location, minimal enhancement, and absence of edema were more frequently observed on images of cavernous angioma compared to those of hemorrhagic ependymoma (p cavernous angioma included increased longitudinal spreading of the hemorrhage (6/7, 86 %) and emergence of high signal intensity on T1WI (1/7, 14 %). Small size, eccentric axial location, minimal enhancement, and absence of edema are significant MRI findings that may be used to distinguish Type I and Type II spinal cavernous angiomas from hemorrhagic ependymomas. Furthermore, longitudinal spreading of the hemorrhage may be observed on follow-up MRIs of cavernous angiomas.

    Paranasal sinus lymphoma is a rare clinical entity. We conducted a retrospective case series of 68 patients with biopsy-confirmed paranasal sinus lymphoma with attention on systemic disease association. Of 63 patients with paranasal sinus lymphoma, 35 (56%) had systemic involvement. Four patient groups were identified: (1) primary paranasal sinus lymphoma (44%); (2) systemic disease occurring concurrently with paranasal sinus lymphoma (25%); (3) paranasal sinus lymphoma with relapse of preexisting systemic lymphoma (22%); and (4) progression to systemic disease after primary paranasal sinus lymphoma (8%). Most of the patients with systemic disease were diagnosed at 50 + years and had positive smoking histories. There was a trend toward disease activity in the neighboring ocular location. For patients with preexisting systemic lymphoma, the mean time to paranasal sinus lymphoma was 65 months. When systemic lymphoma developed after localized paranasal sinus lymphoma, mean time to progression was 23 months. Diffuse large B cell lymphoma was the most common paranasal sinus lymphoma. There is a risk of systemic involvement during the disease course of paranasal sinus lymphoma. Biopsy is the preferred first management step and should precede debulking or mass resection in nonemergent cases. © 2017 Wiley Periodicals, Inc.

    Subperiosteal orbital abscesses (SPOAs) secondary to acute sinusitis are rare occurrences in the pediatric age group, more so in the neonatal period. Here, a rare case of SPOA in a 38-day-old newborn later drained via endoscopic sinus surgery is included also. This review describes the demographic data, clinical history, treatment, microbiology results, complications, and outcome. The admission records for all the patients who were admitted to the Pediatric Surgical Ward in Sarawak General Hospital, Kuching, Malaysia, between January 2004 and May 2009 were retrospectively reviewed. Records of patients who presented with preseptal cellulitis, orbital cellulitis, subperiosteal abscess (extraconal), orbital abscess (intraconal), and cavernous sinus thrombosis were closely studied. Ophthalmology consultations were obtained in all these cases. Ultimately, 3 patients having SPOA secondary to acute sinusitis were selected for this review. All patients were male with rapid onset of periorbital signs, absence of purulent rhinorrhea, and presence of significant thrombocytosis (exceeding 500 × 10(9)/L). The 38-day-old newborn had mixed infection of methicillin-resistant coagulase-negative Staphylococcus bacteremia and local Acinetobacter eye infection with Staphylococcus aureus in the SPOA. All had medially located SPOA that was adequately drained via endoscopic sinus surgery, resulting in full recovery. Newborns with preexisting risk factors and immature immunity are at risk of severe and rare infections. Contrast-enhanced paranasal sinus computed tomographic scan is mandatory and reliable to differentiate preseptal and postseptal orbital infection, as both conditions can present similarly and rapidly deteriorate. In the contrast-enhanced computed tomography-demonstrable SPOA, endoscopic sinus surgery drainage of the abscess proved to be safe and reliable as the main treatment modality. All patients recovered well without complications. Copyright © 2011 Elsevier Inc. All

    Trigeminal neuralgia is classically associated with neurovascular compression of the trigeminal nerve, at the root entry zone (REZ). However, patients are occasionally affected by intra-axial involvement of trigeminal sensory fibers caused by demyelinating diseases, strokes and, rarely, pontine cavernous malformations. We discuss the management strategies and decision-making process in a 55-year-old patient, affected by trigeminal neuralgia with 2 potential causative mechanisms: a neurovascular conflict at the trigeminal REZ and an ipsilateral cavernous malformation at the pontine nucleus of the trigeminal nerve.

    2013-10-01

    On the basis of strong research evidence, the pathogenesis of sinusitis involves 3 key factors: sinusostia obstruction, ciliary dysfunction, and thickening of sinus secretions. On the basis of studies of the microbiology of otitis media, H influenzae is playing an increasingly important role in the etiology of sinusitis, exceeding that of S pneumoniae in some areas, and b-lactamase production by H influenzae is increasing in respiratory isolates in the United States. On the basis of some research evidence and consensus,the presentation of acute bacterial sinusitis conforms to 1 of 3 predicable patterns; persistent, severe, and worsening symptoms. On the basis of some research evidence and consensus,the diagnosis of sinusitis should be made by applying strict clinical criteria. This approach will select children with upper respiratory infection symptoms who are most likely to benefit from an antibiotic. On the basis of some research evidence and consensus,imaging is not indicated routinely in the diagnosis of sinusitis. Computed tomography or magnetic resonance imaging provides useful information when complications of sinusitis are suspected. On the basis of some research evidence and consensus,amoxicillin-clavulanate should be considered asa first-line agent for the treatment of sinusitis.

    Cholesterol granuloma (CG) is usually associated with chronic middle ear disease, and is not common in the paranasal sinuses. Additionally, it is very rare for cases of CG to be associated with a fungal infection. However, in this paper, we report a case of sphenoid sinus CG that is associated with aspergilloma in a 78- year-old male patient who presented with right hemifacial pain, headache and toothache. CT revealed the presence of an expansile cystic mass lesion in the sphenoid sinus that showed a high signal intensity on both the T1 and T2 weighted images. This mass was later determined to be CG. The suspected etiologic mechanisms of both CG and aspergilloma of the paranasal sinuses are similar, and impaired drainage and obstruction of the ventilation of the paranasal sinuses are considered to be the causative mechanism of both diseases. Overall, the results of this study indicate that the use of MRI findings could be helpful for differentiating CG from other paranasal sinus mass lesions

    This work focuses on elucidating the effects of impeller size and speed on `cavern' formation in Herschel-Bulkley fluids using CFD simulations. `Caverns' are defined as the well-mixed regions within the fluid usually encasing the impeller where shear stress imparted by the impeller overcomes the material yield stress. The caverns are often surrounded by zones of stagnant fluid isolated from bulk flow, wherein mass transfer is mainly restricted to diffusion, making them adverse to mixing quality. Numerous models have been developed to predict cavern size including the spherical, cylindrical and toroidal models. Due to its prevalence as a means of comparison in modern experiments, the Elson et al. experiment is replicated for a number of rotational speeds (4, 8 and 12 Hz) and three geometrically-similar Rushton turbines using the code Blue which facilitates the `measurement' of cavern size and depth among other parameters.

    This 15-year-old boy with a tentorial cavernous angioma reported occasional headache and scintillation in his left visual field. Magnetic resonance imaging revealed a well-demarcated, homogeneously enhanced tumor originating from the right cerebellar tentorium and extending into both the supratentorial and infratentorial spaces. Although a meningioma was suspected, vertebral artery angiography revealed a thickened meningeal branch originating from the right posterior inferior cerebellar artery and flecked tumor stain with pooling of contrast medium until the late venous phase. A cavernous angioma of the tentorium was suspected based on this finding, and as expected from the radiological findings, profuse bleeding was encountered during tumor removal. The histological diagnosis was a cavernous angioma. A cavernous angioma of the tentorium is extremely rare but should be differentiated from a meningioma preoperatively given that a cavernous angioma of dural origin tends to bleed massively during removal.

    Improvements in identification, imaging, and visualization of the cavernous nerves during radical prostatectomy, which are responsible for erectile function, may improve nerve preservation and postoperative potency. Optical coherence tomography (OCT) is capable of real-time, high-resolution, cross-sectional, in vivo tissue imaging. The rat prostate serves as an excellent model for studying the use of OCT for imaging the cavernous nerves, as the rat cavernous nerve is a large, visible, and distinct bundle allowing for easy identification with OCT in addition to histologic confirmation. Imaging was performed with the Niris OCT system and a handheld 8 Fr probe, capable of acquiring real-time images with 11-μm axial and 25-μm lateral resolution in tissue. Open surgical exposure of the prostate was performed on a total of 6 male rats, and OCT images of the prostate, cavernous nerve, pelvic plexus ganglion, seminal vesicle, blood vessels, and periprostatic fat were acquired. Cavernous nerve electrical stimulation with simultaneous intracorporeal pressure measurements was performed to confirm proper identification of the cavernous nerves. The prostate and cavernous nerves were also processed for histologic analysis and further confirmation. Cross-sectional and longitudinal OCT images of the cavernous nerves were acquired and compared with histologic sections. The cavernous nerve and ganglion could be differentiated from the surrounding prostate gland, seminal vesicle, blood vessels, bladder, and fatty tissue. We report preliminary results of OCT images of the rat cavernous nerves with histologic correlation and erectile stimulation measurements, thus providing interpretation of prostate structures as they appear in OCT images.

    Abstract Though an association between autoimmune diseases and sick sinus syndrome has been reported, there has been no report on the association of hypopituitarism and sick sinus syndrome. Herein, we provide the first case report of hypopituitarism accompanying sick sinus syndrome in a 51-year-old woman presented to our hospital with syncope due to cardiac arrest. The patient was successfully managed by pacemaker installation and hormone replacement therapy.

    Silent sinus syndrome (SSS) is an uncommon disease characterised by enophthalmos, caused by ipsilateral maxillary sinus atelectasis. The diagnosis is clinical with radiological confirmation. The treatment has two objectives: to regulate the aeration of the maxillary sinus through achieving normal nasal cavity drainage and to restore the orbital architecture. A case of SSS treated in our hospital in a single surgical intervention is reported. Copyright © 2011 Elsevier España, S.L. All rights reserved.

    Sarcoidosis is a chronic systemic disease of unknown etiology characterized by non-caseating granulomatous inflammation of various organs. The records of 2319 patients with the diagnosis of sarcoidosis were reviewed to determine the incidence of nasal involvement. Seventeen patients or approximately 1% of the patients with sarcoidosis had histologically proven nasal mucosa involvement. These patients had symptoms of nasal crusting, congestion, epistaxis, pain, or anosmia. The clinical findings in these patients included friable nasal mucosa, nasal polyps, or a characteristic submucosal nodularity. Most patients also had abnormal sinus roentgenograms with either thickening of the sinus mucosa or opacification of the sinuses. Biopsy of the nasal mucosa shows typical non-caseating granulomas, but care must be exercised to exclude other causes of granulomatous inflammation of the nasal mucosa including tuberculosis, fungal infections, and other idiopathic granulomatous diseases such as Wegener's granulomatosis and Churg-Strauss syndrome. The treatment of nasal sarcoidosis has consisted of systemic steroids and in some cases topical beclomethasone dipropionate.

    The role of fungi in chronic rhinosinusitis (CRS) is not clear. Fungi can be detected in the nose and paranasal sinuses of virtually all CRS patients; however, they also appear to be present in healthy controls. Various theories attempt to explain the mechanisms by which fungi can exert an effect on sinus mucosa in susceptible individuals. Further studies are necessary to clarify the role of fungi in CRS, which fungal organisms (if any) are pathogenic, and what exactly characterizes the immunologic response to fungi that may result in the development of disease. However, in the absence of convincing immunologic data and evidence of clinical improvement of CRS after antifungal therapy, the case against the fungus remains unproven.

    Inflammatory conditions belong to the most important diseases of the orbit. Children and adolescents are mostly affected and the most common cause is secondary pathogen invasion from acute sinusitis. However in adults most cases involve idiopathic orbital inflammation, previously termed pseudotumor orbitae. Clinical presentation may include painful exophthalmus, skin redness and warming, chemosis and disturbed eye motility. The challenge for imaging investigations, mainly a combination of CT scanning and MRI, is to distinguish inflammatory from malignant conditions, to define the extent of lesions and to document possible complications, such as cavernous sinus thrombosis, meningoencephalitis or cerebral abscesses. Serious potential consequences of orbital infections, including loss of vision or death, are still a risk factor and must be averted by avoidance of delays in diagnosis and appropriate clinical management. (orig.) [German] Entzuendliche Veraenderungen zaehlen zu den wichtigen Erkrankungen der Orbita. Meist sind Kinder und Jugendliche betroffen, wobei eine fortgeleitete Infektion der Nasennebenhoehlen die haeufigste Ursache darstellt. Bei Erwachsenen handelt es sich in den meisten Faellen um eine idiopathische Orbitaentzuendung - frueher unter dem Begriff Pseudotumor orbitae zusammengefasst. Zu den Leitsymptomen zaehlen schmerzhafter Exophthalmus, Ueberwaermung und Roetung der Haut, Chemosis sowie eine Bewegungseinschraenkung des Bulbus. Die Rolle bildgebender Verfahren - hier ergaenzen sich Computer- und Magnetresonanztomographie - besteht in der Differenzierung inflammatorischer und tumoroeser Prozesse und insbesondere in der Darstellung der Laesionsausdehnung sowie dem Nachweis von Komplikationen, wie einer Sinus-cavernosus-Thrombose, einer Meningoenzephalitis oder zerebralen Abszessen. Auch heute noch koennen Infektionen der Orbita schwerwiegende Folgen wie komplette Erblindung oder Tod nach sich ziehen. (orig.)

    To observe the apoptosis in penile corpus cavernous after neurotomy. After neurotomy, 78 SD rats were randomly assigned to experimental and normal control groups at day 1, 2, 4, 8, 16, and 32 time point. The quality was measured by DNA Ladder and the quantitation was measured by TUNEL. The location of apoptosis was detected by dual stained with immunohistochemistry and TUNEL. After transaction of cavernous nerve, dorsal never, and both nerves, the apoptosis in experimental and control group showed a statistically significant difference (P0.0046). There was a statistically significant difference in apoptosis between cavernous smooth muscle cell and endothelial cell groups (PCavernous nerve transection induces apoptosis in smooth muscle cells of the rat penis, but nor does dorsal nerve transaction alone. There is no statistically significant difference in apoptosis between cavernous nerve injury alone and combination injuries of cavernous nerve and dorsal nerve.

    Full Text Available A 13-month-old, neutered, male Golden retriever presented with seizures and progressive depression. Clinical and neurological assessment was consistent with severe intracranial disease. The neurological condition progressively deteriorated and magnetic resonance imaging (MRI revealed the presence of a large, contrast-enhancing, space-occupying mass in the right cerebral hemisphere. Therapy with corticosteroids, mannitol and furosemide ameliorated the signs of depression and ataxia, but the owner elected euthanasia after 1 week. Post mortem examination of the brain confirmed the presence of a large haemorrhagic lesion in the right olfactory lobe, the histopathological appearance of which was consistent with cerebral cavernous haemangioma. This is the 1st case describing the MRI appearance of a cavernous haemangioma of the cerebrum in the veterinary literature.

    Full Text Available Prophylactic cranial irradiation has been a part of multimodality management of acute lymphoblastic leukemia (ALL. With optimum treatment and the resultant long-term cure rates, long-term side effects of radiation including radiation-induced neoplasms have been increasingly unearthed. We report a rare case of development of both a meningioma and a cavernous angioma following prophylactic cranial irradiation as a part of treatment of ALL. Regular follow-up and high index of suspicion for late radiation sequelae after treatment are therefore justifiable in leukemia survivors with history of prophylactic cranial irradiation.

    Cavernous hemangioma is also called as ‘ANGIOMA CAVERNOSUM’ or ‘CAVERNOMA’ as benign lesion of blood vessels. They are similar to strawberry hemangioma but deeply situated. Although most often associated with skin it is also sometimes found in mucous membrane, brain and the viscera. The diagnosis of hemangiomas is mainly based on clinical evaluation . Isolated hemangiomas in the tonsillar tissue is a rare occurance. In this we report had a case of adult tonsillar hemangioma of left side associated with recurrent tonsillitis . He was effectively managed surgically without any complications. PMID:24298502

    A rare case of giant uterine lymphangioma was experienced. A 44-year-old female noted a rapidly grown abdominal tumor and its accompanied symptoms, progressive abdominal distension, lumbago, and developed leg edema. Ultrasonography made a possible diagnosis of a huge ovarian tumor; postoperative diagnosis was cavernous lymphangioma arising from the uterus. According to the literature, lymphangioma itself is a rare tumor, and giant lymphangioma arising from uterine corpus is extremely rare. We experienced an extremely rare case of uterine lymphangioma and ultrasound tomography better imaged the tumor inside.

    Full Text Available Orbital cellulitis is an emergency situation in children. Rapid diagnosis and appropriate management are mandatory to save both vision and life. In contrast, melioidosis infection causing orbital cellulitis with intracranial infection is a rare situation in children, and requires an aggressive management. Poor response or worsening of clinical condition despite appropriate management of paediatric orbital cellulitis should alert the physician of this devastating infection, especially when it occurs in those living in endemic areas.

    Full Text Available Introduction: Maxillary sinus can be visualized in both two-dimensional and three-dimensional images. Computed tomography (CT is considered the gold standard method for the examination of maxillary sinus. Cone beam computed tomography (CBCT addresses the limitation of CT and provides many dental advantages. It can provide valuable knowledge about the pathology with limited exposure and low cost compared with other imaging used for diagnostic purposes. Aims and Objectives: The aim of the study is to analyze the prevalence of pathological changes in maxillary sinus of asymptomatic cases using CBCT for diagnostic purposes. Materials and Methods: This retrospective study evaluated 231 patients for incidental maxillary sinus pathologies. Pathological findings were categorized as mucosal thickening, polypoid mucosal thickening, radiopacification, and no pathological findings. Evaluation of pathological findings was done using factors of age and gender. Results: The present study showed 86 cases with maxillary sinus pathology and 145 cases with no pathological findings. Patients with maxillary sinus pathology were mostly diagnosed with mucosal thickening on both sides. In right maxillary sinus, 45 cases (52.3% showed mucosal thickening, and on the left side 36 cases (41.9% were diagnosed with mucosal thickening. Among 86 cases reported, 20 right maxillary sinus (23.3% and 25 left maxillary sinus (29.1% showed no signs of pathology. Conclusion: The incidental maxillary sinus pathologies are highly prevalent in asymptomatic patients. Therefore, oral radiologists should be aware of these incidental findings which will help in early diagnosis and treatment of disease.

    Myxoma is a slow growing, benign neoplasm, which pathogenesis still remains disputed. The lesion has well-defined borders but a true capsule is absent. Because of that myxoma can be locally invasive causing bone destruction. A change is mainly observed among persons between 20-30 years of age and is very uncommon in the pediatric population. Most myxomas are observed in myocardium, but rarely may also manifest in the head and neck region. In the paper we describe an unusual case of myxoma of maxillary sinus in a female infant. Diagnostic challenges, treatment, outcome, post-operative follow-up are discussed as well as a review of the literature in order to present many features of this rare pathology. © 2016 MEDPRESS.

    Summary We report our experience in treatment of traumatic direct carotid cavernous fistula (CCF) via endovascular intervention. We hereof recommend an additional classification system for type A CCF and suggest respective treatment strategies. Only type A CCF patients (Barrow's classification) would be recruited for the study. Based on the angiographic characteristics of the CCF, we classified type A CCF into three subtypes including small size, medium size and large size fistula depending on whether there was presence of the anterior carotid artery (ACA) and/or middle carotid artery (MCA). Angiograms with opacification of both ACA and MCA were categorized as small size fistula. Angiograms with opacification of either ACA or MCA were categorized as medium size fistula and those without opacification of neither ACA nor MCA were classified as large size fiatula. After the confirm angiogram, endovascular embolization would be performed impromptu using detachable balloon, coils or both. All cases were followed up for complication and effect after the embolization. A total of 172 direct traumatic CCF patients were enrolled. The small size fistula was accountant for 12.8% (22 cases), medium size 35.5% (61 cases) and large size fistula accountant for 51.7% (89 cases). The successful rate of fistula occlusion under endovascular embolization was 94% with preservation of the carotid artery in 70%. For the treatment of each subtype, a total of 21/22 cases of the small size fistulas were successfully treated using coils alone. The other single case of small fistula was defaulted. Most of the medium and large size fistulas were cured using detachable balloons. When the fistula sealing could not be obtained using detachable balloon, coils were added to affirm the embolization of the cavernous sinus via venous access. There were about 2.9% of patient experienced direct carotid artery puncture and 0.6% puncture after carotid artery cut-down exposure. About 30% of cases

    Odontogenic sinusitis and sinonasal complications of dental disease or treatment (SCDDT) play a relevant, often underappreciated role in paranasal sinus infections. Treating SCDDT patients requires tailored medical and surgical approaches in order to achieve acceptable success rates. These approaches differ from common rhinogenic sinusitis treatment protocols mostly because of the different etiopathogenesis. Our study comprehensively evaluated microbiology and antibiotic resistance in SCDDT patients and compared findings with a control group of patients affected by rhinogenic sinusitis. We performed microbiological sampling during surgery on 28 patients with SCDDT and 16 patients with chronic rhinosinusitis with nasal polyps (CRSwNP). Colonies were isolated, Gram-stained, and the species identified using classic biochemical methods. These results were confirmed by DNA pyrosequencing, and then the resistance profile of each SCDDT isolate to various antibiotics was tested. Microbial growth was observed in all SCDDT patients, whereas samples from 60% of patients in the control group failed to yield any bacterial growth (p sinus of SCDDT patients, these infections should be regarded as a different class of conditions from rhinogenic sinusitis. Our findings support the need for different approaches in the treatment of SCDDT patients. © 2015 ARS-AAOA, LLC.

    Nasal irrigation is widely used in treating sinonasal diseases. Not only does it remove static secretions and promote mucociliary clearance, but, in chronic rhinosinusitis, nasal flush is also a potential route for topical drug administration into paranasal sinuses. A clinical study was conducted to investigate how well nasal irrigation could reach paranasal sinuses with the ostiomeatal units blocked in chronic rhinosinusitis. This study was performed to (1) assess the ability of a nasal douche and spray to deliver a solution into the paranasal sinuses in chronic rhinosinusitis and (2) compare the performance of the two techniques. Fourteen patients, with bilateral chronic rhinosinusitis, underwent nasal irrigation with 140 mg/mL of iodinated contrast solution by 40 mL of douching using an irrigation syringe in one side, and 10 mL of spraying in the other side. A computed tomography scan was undertaken for each patient to determine the volume and the distribution of staining in the nose and paranasal sinuses. Only two patients had any staining, with a small amount present in a total of three maxillary sinuses (0.10 mL, 0.04 mL, and 0.13 mL). The mean volumes of paranasal sinus staining by nasal douche and nasal spray were 0.0093 and 0.01 mL, respectively. We found that the two techniques had a similar performance. Both of them delivered only a small amount of the solution, if any, into the sinuses (with a mean difference of -0.0007 mL; 95% CI, -0.02-0.02 mL; p = 0.94). Nasal douche and spray is not effective in delivering a nasal irrigation solution into paranasal sinuses in chronic rhinosinusitis.

    Tubercular infection of the nasal cavity is an infrequently encountered condition. More so, after the discovery of relevant antibiotics, nasal sinus tuberculosis is not commonly seen. Few cases have reported tuberculosis of the paranasal sinuses, nasopharynx and larynx. With the increasing incidence of HIV, these rare forms of infection have started re-emerging. We present a case of a middle aged man presenting with nasal cavity lesion along with pulmonary tuberculosis, which came to light only after the diagnosis of maxillary sinus tuberculosis. 2014 BMJ Publishing Group Ltd.

    Capillary hemangioma (capillary lobular hemangioma) and cavernous hemangioma (venous malformation) are relatively common oral tumors/malformations and are characterized by increased numbers of normal and abnormal blood vessels. However, the causes of these lesions are not well understood. CD105 (endoglin) is predominantly expressed in proliferating blood endothelial cells (ECs). We analyzed expressions of CD105, CD34, von Willebrand factor, Ki-67, cyclooxygenase-2 (COX-2), and vascular endothelial growth factor (VEGF)-A in 31 capillary hemangiomas and 34 cavernous hemangiomas. Staining scores were calculated as the product of the proportion score and intensity score. Morphologically normal oral mucosa specimens (n = 10) were simultaneously evaluated as normal controls. As compared with cavernous hemangiomas and normal controls, capillary hemangiomas had higher staining scores for CD105, VEGF-A, and COX-2. The Ki-67 labeling index was significantly higher in capillary hemangiomas than in cavernous hemangiomas and normal controls (P characteristics of capillary and cavernous hemangiomas are quite different. The ECs of capillary hemangiomas actively proliferated and were generally regulated by VEGF-A. In contrast, the ECs of cavernous hemangiomas lacked proliferative activity. These results suggest that angiogenesis and vasodilatation of pre-existing blood vessels are important in the development of capillary hemangioma and cavernous hemangioma, respectively.

    2016-09-01

    Full Text Available Introduction: Inappropriate sinus tachycardia is generally defined as an elevated resting heart rate (>90–100 bpm with an exaggerated response to physical or emotional stress and a clearly sinus mechanism which is not secondary to a diagnosed somatic disease. Anxiety, a significant risk factor for cardiovascular disease, is recently recognized as a crucial issue in younger and older adults, with a causal relation to other risk factors, such as depression, substance use, overweight, sleep difficulties, or a sedentary life style. The aim of the study was to evaluate a possible relation between the level of anxiety, control of emotions in patients with manifestation of inappropriate sinus tachycardia and diagnosis of this syndrome. Material and methods: The study included 33 female patients with inappropriate sinus tachycardia (age range 31.8 ± 8.72 and 33 women (28.7 ± 4.4 without any cardiac diseases. The diagnosis of inappropriate sinus tachycardia was given by a cardiologist during hospitalisation of the patients in the 2nd Department of Cardiology and Department of Electrocardiology, Medical University of Lodz, Lodz, Poland. For psychological assessment the State-Trait Anxiety Inventory and Courtauld Emotional Control Scale both self-report, paper and pencil inventories were used. Results: A statistically significant difference was found between the group of women with inappropriate sinus tachycardia and the group of healthy women regarding the Anxiety-Trait. The results of the study have shown no other statistically significant differences between tested groups. Conclusions: Inappropriate sinus tachycardia is related to increased anxiety. More clinical trials are needed to confirm its psychogenic basis.

    Full Text Available The purpose: to prove diagnostic capabilities of modern radiation techniques in odontogenic maxillary sinusitis. Material and methods: The study involved 546 patients with sinusitis. The following methods have been used: X-ray of the paranasal sinuses, contrast maxillary sinus radiography, contact intraoral radiographs, orthopantomography, computer tomography and magnetic resonance imaging. Results. In 7,9% of cases the presence of odontogenic sinusitis has been established, in 92,1 % rhinogenous sinusitis has been revealed. The work provides information about the effectiveness of various radiation techniques in the diagnosis of odontogenic sinusitis. Conclusion. For suspected odontogenic sinusitis, treatment of choice includes the combined use of X-ray of the paranasal sinuses in the mentoanterior projection and contact intraoral radiographs of «causal teeth». Computer tomography is the most informative additional method to clarify the diagnosis of odontogenic sinusitis.

    1985-04-01

    Beta adrenergic receptor binding was performed with /sup 125/I iodocyanopindolol on human cavernous tissue membrane fractions from normal tissue and transsexual procedures obtained postoperatively, as well as from postmortem sources. Isotherm binding studies on normal fresh tissues indicated that the receptor density was 9.1 fmoles/mg. with a KD of 23 pM. Tissue stored at room temperature for 4 to 6 hours, then at 4C in saline solution for 19 to 20 hours before freezing showed no significant changes in receptor density or affinity, and provided evidence for the stability of postmortem tissue obtained within the same time period. Beta receptor density of 2 cavernous preparations from transsexual procedures was not significantly different from normal control tissues, and showed that high concentrations of estrogen received by these patients had no effect on beta adrenergic receptor density. Displacement of /sup 125/iodocyanopindolol by 5 beta adrenergic agents demonstrated that 1-propranolol had the greatest affinity followed by ICI 118,551, zinterol, metoprolol and practolol. When the results of these displacement studies were subjected to Scatfit, non- linear regression line analysis, a single binding site was described. Based on the relative potency of the selective beta adrenergic agents it appears that these receptors were of the beta 2 subtype.

    Hanging casing strings are used for oil and brine transfer in the domal salt storage caverns of the Strategic Petroleum Reserve (SPR). Damage to these casings is of concern because hanging string replacement is costly and because of implications on cavern stability. Although the causes of casing damage are not always well defined, many events leading to damage are assumed to be the result of salt falls impacting the hanging strings. However, in some cases, operational aspects may be suspected. The history of damage to hanging strings is updated in this study to include the most recent events. Potential general domal and local operational and material factors that could influence the tendency for caverns to have salt falls are examined in detail. As a result of this examination, general factors, such as salt dome anomalies and crude type, and most of the operational factors, such as geometry, location and depressurizations, are not believed to be primary causes of casing damage. Further analysis is presented of the accumulation of insolubles during cavern solutioning and accumulation of salt fall material on the cavern floor. Inaccuracies in sump geometry probably make relative cavern insolubles contents uncertain. However, determination of the salt fall accumulations, which are more accurate, suggest that the caverns with the largest salt fall accumulations show the greatest number of hanging string events. There is good correlation between the accumulation rate and the number of events when the event numbers are corrected to an equivalent number for a single hanging string in a quiescent, operating cavern. The principal factor that determines the propensity for a cavern to exhibit this behavior is thought to be the effect of impurity content on the fracture behavior of salt.

    The authors report 14 cases of Wegener granulomatosis in which one or more paranasal sinuses were obliterated by bone. The maxillary antra were involved in all cases, with the other sinuses being affected less frequently. These changes are thought to result from chronic bacterial sinusitis superimposed on the granulomatous vasculitic process. Computed tomography dramatically demonstrated the bone changes, consisting of a combination of sinus wall thickening and trabeculated new bone formation within the sinuses.

Our study shows a non-invasive treatment option to recovery after cavernous nervous damage. The assessment of changes in the intracavernous pressure and karyometry demonstrates the protective effect of annexin-A1 in an animal model of cavernous nerve injury. We found that annexin-A1 effectively preserved erectile function, evidently through significantly protecting the corpus cavernosum tissue against fibrosis. • To evaluate the protective effect of annexin-A1 against irreversible damage to cavernous tissue after cavernous nerve injury. • Thirty Sprague-Dawley male rats were divided into 3 groups; sham-operated rats (n= 10), bilateral cavernous nerve injury treated intravenously with 100 µg/kg annexin-A1 (n= 10), and a crush group of rats submitted to bilateral cavernous nerve injury and vehicle (n= 10). Groups were compared in respect to intracavernous pressure and karyometric parameters. • After annexin-A1 treatment, the maximum changes in intracavernous pressure responses were significantly higher in the annexin-A1 group compared to the vehicle-only group on the 7(th) postoperative day (p-value cavernous nerve injury.

    Cerebral cavernous malformations (CCMs) are a distinct cerebrovascular disease. A fraction of CCMs present as diffuse manifestations distributed over the cerebral hemispheres, cerebellum, and brainstem. The purpose of the present study was to explore the clinical picture of such CCMs. This study assessed the appearance of CCMs on magnetic resonance (MR) images, the presence of genetic mutations using the polymerase chain reaction method, and disease course over long-term follow-up in a total of 10 patients with diffuse CCMs. The 10 patients were Japanese and comprised 5 males and 5 females with a mean age of 48.7years. Three of them presented with seizures, two with headache and intracerebral hemorrhage, two with numbness, and one with dizziness, while the remaining two were asymptomatic. Genetic analysis revealed CCM1 mutations in four patients, CCM2 mutations in three, and a CCM3 mutation in one. In a family with 2 CCM2 patients, the appearance of sustained diffuse CCMs on MR images significantly differed between the 2 patients despite the mutation being identical. During the mean follow-up period of 13.7years, none of the 10 patients showed evidence of neurological deterioration or symptomatic hemorrhage. The appearance of their CCMs on MRI did not show significant changes. Eight patients maintained normal neurological function. CCMs with diffuse manifestation is a hereditary disease with satisfactory prognosis. Unrecognized genomic mutations may be involved in the genesis of these CCMs. Copyright © 2016 Elsevier B.V.

    Bilateral cavernous nerve injury (BCNI) causes profound penile changes such as apoptosis and fibrosis leading to erectile dysfunction (ED). Histone deacetylase (HDAC) has been implicated in chronic fibrotic diseases. This study will characterize the molecular changes in penile HDAC after BCNI and determine if HDAC inhibition can prevent BCNI-induced ED and penile fibrosis. Five groups of rats (8-10 weeks, n = 10/group) were utilized: (i) sham; (ii and iii) BCNI 14 and 30 days following injury; and (iv and v) BCNI treated with HDAC inhibitor valproic acid (VPA 250 mg/kg; 14 and 30 days). All groups underwent cavernous nerve stimulation (CNS) to determine intracavernosal pressure (ICP). Penile HDAC3, HDAC4, fibronectin, and transforming growth factor-β1 (TGF-β1) protein expression (Western blot) were assessed. Trichrome staining and the fractional area of fibrosis were determined in penes from each group. Cavernous smooth muscle content was assessed by immunofluorescence to alpha smooth muscle actin (α-SMA) antibodies. We measured ICP; HDAC3, HDAC4, fibronectin, and TGF-β1 protein expression; penile fibrosis; penile α-SMA content. There was a voltage-dependent decline (P erectile responses to CNS (P dysfunction. Pharmacological inhibition of HDAC prevents penile fibrosis, normalizes fibronectin expression, and preserves erectile function. The HDAC pathway may represent a suitable target in preventing the progression of ED occurring post-radical prostatectomy. © 2014 International Society for Sexual Medicine.

    The ethmoidal sinus often plays a key role in recurring infectious sinusitis. Infections arising from this area are the cause of failure of some conventional and radical operative therapies. The case studies presented here demonstrate that transnasal surgery of the ethmoidal sinus because of an inflammatory process, can cause serious complications. Worsening of the vision with opacity of the paranasal sinuses is not always due to an inflammation. Corresponding disease courses which indicate a connection between eye function disturbances and processes of the paranasal sinuses are presented. A correlation between inflammatory and tumorous diseases of the adjacent paranasal sinuses with ophthalmologic signs can be shown in many patients via computed tomography and magnetic resonance imaging. These methods contribute to the diagnosis of the disease, determination of complications, differential diagnostic evaluation of benign and malignant space-occupying lesions, tumour staging, therapy planning, control of the disease course, early recognition of tumour recurrence and documentation.

  13. Geometrical versus rheological transient creep closure in a salt cavern

    Science.gov (United States)

    Bérest, Pierre; Karimi-Jafari, Mehdi; Brouard, Benoît

    2017-11-01

    An in-situ test performed in a brine-filled cavern proves that, when brine pressure decreases rapidly, the creep closure rate increases drastically. Conversely, a rapid pressure increase leads to ;reverse; creep closure: cavern volume increases, even when, at cavern depth, fluid pressure is lower than geostatic pressure. It is tempting to explain these two phenomena by transient salt creep, a characteristic feature of salt rheological behavior commonly observed during laboratory creep tests. In fact, computations performed on an idealized cylindrical cavern excavated from a Norton-Hoff rock mass (a constitutive law that includes no transient component) prove that these two phenomena are, at least partly, of a structural nature: their origin is in the slow redistribution of stresses following any pressure change.

    Full Text Available Purpose: To report the response of cavernous haemangioma of the disc to PDT. Methods and Patients: A 32 years old lady presented to us with complaints of sudden onset of blurry vision in her right eye. What seemed initially as polypoidal choroidal vasculopathy turned out as cavernous haemangioma of the disc after pneumatic displacement of the sub-retinal haeme. She was treated with PDT as she was prone to recurrent haemorrhage from the lesion due to her low platelet count. Results: Complete regression of the cavernous haemangioma was noted as early as the second week itself and remained regressed for 4 months. Conclusion: PDT can be safe option for patients presenting with symptomatic cavernous haemangioma of the disc or retina.

    2013-12-01

    Maxillary sinusitis of dental origin (MSDO) has been described for decades, but tends to be overlooked as a possible cause of chronic sinusitis by both clinicians and radiologists. The incidence of MSDO in published series is reported to be from 10% to 40% in bacterial sinusitis. We present this series to highlight clinical and radiologic indicators of MSDO. Databases from the authors' otolaryngology and endodontic practices were reviewed to identify patients who had been seen mutually. Sixty-seven (67) patients were identified. Both authors then reviewed the clinical records and associated computed tomography (CT) scans and determined that 31 patients had MSDO and 2 of had bilateral MSDO, for a total of 33 cases. The clinical and radiologic features related to these cases were then tabulated. The clinical characteristics of the 33 cases of MSDO were as follows: sinus pain (88%), postnasal drainage (64%), congestion (45%), maxillary toothache (39%), and foul drainage (15%). Radiographic CT findings of MSDO showed periapical abscess in 18 cases (55%), periodontal abscess in 3 cases (9%), and no obvious dental pathology in 12 cases (36%). The extent of associated sinusitis was variable from mucoperiosteal thickening to florid unilateral sinusitis involving multiple sinuses. Eighteen maxillary sinuses (55%) were found to have either patent maxillary infundibula or prior surgical antrostomy. Twenty-four patients (77%) had unilateral maxillary sinus disease. MSDO should be considered highly likely when radiographic evidence of dental pathology is associated with maxillary sinus disease. Regardless of negative CT evidence of dental pathology, MSDO should be suspected when unilateral maxillary sinus disease is seen, particularly when associated with a patent infundibulum. When MSDO is suspected, a clinical endodontic examination should be performed to rule out or treat an odontogenic etiology. © 2013 ARS-AAOA, LLC.

    Background Upper respiratory diseases have been linked with lower respiratory diseases. However, the long-term effect of sinusitis on the clinical outcomes of asthma has not been fully evaluated. Objective The aim of this study was to investigate the impact of sinusitis on the disease progression of asthma. Methods Seventy-five asthmatic patients confirmed with the methacholine bronchial provocation test or bronchodilator response were included. The study patients underwent paranasal sinus x-ray upon their asthma evaluation and they visited the hospital at least 3 years or longer. We retrospectively reviewed their medical records and compared data according to the presence of comorbid sinusitis. Results Among the 75 asthmatic subjects, 38 subjects (50.7%) had radiologic evidence of sinusitis. Asthmatics with sinusitis had significantly lower forced expiratory volume in 1 second (FEV1; 79.2% vs. 88.2%) and PC20 values (5.2 mg/mL vs. 8.9 mg/mL) compared to asthmatics without sinusitis at the time of diagnosis. This difference in FEV1 disappeared (82.6% vs. 87.2%) in the 3-year follow-up, although FEV1 was more variable (31.7% vs. 23.5%) and worst FEV1 was also significantly lower in patients with sinusitis compared to those without (70.9% vs. 79.0%). There were no significant differences in the number of hospital visits, acute exacerbations, and scores for the asthma control test. Conclusion Although sinusitis was associated with lower baseline lung function and higher hyperreactivity, sinusitis was not related with significant deterioration in lung function over 3 years of follow-up. Asthmatics with sinusitis showed more variability in lung function during the follow-up period. Healthcare utilization was not different except antibiotics use. PMID:25379482

    Ene, Chibawanye; Kaul, Anand; Kim, Louis

    2017-01-01

    Cerebral cavernous malformations (CCM) are vascular abnormalities of the central nervous system with an incidence of 0.4-0.5% and an annual rate of hemorrhage ranging from 0.7% to 1%. Most lesions are located in the cerebral hemisphere but some occur in deeper locations such as the basal ganglia and pons. The most common symptoms during presentation are headache, seizures, and focal neurologic deficits. Surgery remains the most effective treatment modality for symptomatic CCM, while the management of incidental CCM remains controversial. Factors associated with increased risk of hemorrhage include being female and less than 40 years old. This finding, however, is not consistent in all natural history studies evaluated. During follow-up, the most important and consistent risk factor for rebleed was a prior hemorrhage. Here, we provide an indepth but concise review of the literature regarding the natural history of CCMs. © 2017 Elsevier B.V. All rights reserved.

    2014-01-01

    ABSTRACT Loss-of-function mutations in genes encoding KRIT1 (also known as CCM1), CCM2 (also known as OSM and malcavernin) or PDCD10 (also known as CCM3) cause cerebral cavernous malformations (CCMs). These abnormalities are characterized by dilated leaky blood vessels, especially in the neurovasculature, that result in increased risk of stroke, focal neurological defects and seizures. The three CCM proteins can exist in a trimeric complex, and each of these essential multi-domain adaptor proteins also interacts with a range of signaling, cytoskeletal and adaptor proteins, presumably accounting for their roles in a range of basic cellular processes including cell adhesion, migration, polarity and apoptosis. In this Cell Science at a Glance article and the accompanying poster, we provide an overview of current models of CCM protein function focusing on how known protein–protein interactions might contribute to cellular phenotypes and highlighting gaps in our current understanding.

    To determine whether the wall thickening of the maxillary sinus is a characteristic finding in aspergillosis. In 103 patients, including 26 with aspergillosis, 21 with inverted papilloma (IP), and 56 with unilateral chronic sinusitis, the thickness of the maxillary sinus wall was determined by CT scanning. All cases were proven pathologically, and patients with a history of previous surgery of bone destruction were excluded. Two neuroradiologists retrospectively reviewed the CT scans using bone window settings for sinus wall hyperostosis and the presence of intrasinus calcification. Thickening of the maxillary sinus wall was assessed visually in a semiquantitative manner, and graded as 'none' (absence of thickening), 'mild' (thickening of up to 1.5 times), or moderate ot severe(over 1.5 times thicker than normal contralateral sinus wall at its thickest point). Moderate to severe wall thickening was found only in patients with aspergillosis (21/26, 80.8%). Mild wall thickening was seen in two patients with aspergillosis (2/26, 7.7%), in 12 of 21 with IP (57.1%), and in 5 of 56 with chronic maxillary sinusitis (8.9%). Most cases of chronic maxillary sinusits( 51/56,91.1%), 9/21 IP cases (42.9%), and 3/26 cases of aspergillosis (11.5%) showed no thickening of the maxillary sinus wall. Calcifications were found in 18 patients with aspergillosis (69.2%), in no patient with IP (0%), and in one with chronic maxillary sinusitis (1.8%). We suggest that 'moderate to severe' wall thickening of the maxillary sinus is the characteristic finding of aspergillosis. Although various sinonasal diseases can cause bone change, CT findings of hyperostosis of the maxillary sinus and intrasinus calcification are very helpful in differentiating fungal sinusitis from other types of chronic inflammatory lesions.

    Cerebral cavernous malformations (CCMs) are a cause of stroke and seizure for which no effective medical therapies yet exist. CCMs arise from the loss of an adaptor complex that negatively regulates MEKK3-KLF2/4 signalling in brain endothelial cells, but upstream activators of this disease pathway have yet to be identified. Here we identify endothelial Toll-like receptor 4 (TLR4) and the gut microbiome as critical stimulants of CCM formation. Activation of TLR4 by Gram-negative bacteria or lipopolysaccharide accelerates CCM formation, and genetic or pharmacologic blockade of TLR4 signalling prevents CCM formation in mice. Polymorphisms that increase expression of the TLR4 gene or the gene encoding its co-receptor CD14 are associated with higher CCM lesion burden in humans. Germ-free mice are protected from CCM formation, and a single course of antibiotics permanently alters CCM susceptibility in mice. These studies identify unexpected roles for the microbiome and innate immune signalling in the pathogenesis of a cerebrovascular disease, as well as strategies for its treatment.

  5. Introduction to cerebral cavernous malformation: a brief review

    Science.gov (United States)

    Kim, Jaehong

    2016-01-01

    The disease known as cerebral cavernous malformations mostly occurs in the central nervous system, and their typical histological presentations are multiple lumen formation and vascular leakage at the brain capillary level, resulting in disruption of the blood-brain barrier. These abnormalities result in severe neurological symptoms such as seizures, focal neurological deficits and hemorrhagic strokes. CCM research has identified ‘loss of function’ mutations of three ccm genes responsible for the disease and also complex regulation of multiple signaling pathways including the WNT/β-catenin pathway, TGF-β and Notch signaling by the ccm genes. Although CCM research is a relatively new and small scientific field, as CCM research has the potential to regulate systemic blood vessel permeability and angiogenesis including that of the blood-brain barrier, this field is growing rapidly. In this review, I will provide a brief overview of CCM pathogenesis and function of ccm genes based on recent progress in CCM research. [BMB Reports 2016; 49(5): 255-262] PMID:26923303

    2015-01-01

    Cerebral cavernous malformations (CCM) are vascular lesions which affect up to 0.5% of the general population, predisposing to headaches, seizures, cerebral hemorrhages and focal neurological deficits. CCM occurs in both sporadic and familial forms; familial cases follow an autosomal-dominant mode of inheritance and are caused by mutations in CCM1 (KRIT1), CCM2 (MGC4607), or CCM3 (PDCD10). Somatic mutations within the three CCM genes have been identified in CCM lesions from both sporadic and familial patients. We reviewed articles published in PubMed in English prior to March 2015 and provide an update on CCM mutations and the screening strategies used to identify them. Further, we summarize the specific clinical features related to CCM genotypes. As 5 to 15% of familial CCM cases remain genetically unexplained, we also discuss future approaches to expand understanding of the genetic architecture of CCM. Finally, we discuss possible genetic modifiers of CCM disease severity and progression. Understanding the genetic architecture of CCM is essential for an earlier diagnosis of the disease, predictive testing of at-risk patients, and design of targeted medical therapies of which there are currently none available.

    We describe a case of an elderly patient who presented with right-sided ophthalmoplegia, proptosis, chemosis, and increased intraocular pressure. An angiogram showed feeding vessels from the bilateral internal and external carotid arteries. Our initial attempt to blindly probe the inferior petrosal sinus was unsuccessful. This was followed by a right anterior orbitotomy exposing the superior ophthalmic vein which was directly cannulated with an 18 gauge angiocatheter. However, a proximal third of the superior ophthalmic vein within the orbit which was thrombosed was probed blindly. The thrombosed vein was cannulated with a microcatheter to obtain coil embolization of the carotid cavernous fistula. The implications of the procedure are discussed, given that, to our knowledge, such an endeavor has never been performed. PMID:23761619

    To classify the cerebral cavernous malformations and to investigate the natural history of cavernous malformations according to the classification, 41 patients with 61 cavernous malformations (40 cavernous malformations from 22 patients treated with gamma knife surgery) were regularly followed up using MR imaging for a mean period of 25.5 months in treated cavernous malformations and 20.7 months in untreated cavernous malformations, respectively. Cavernous malformations were classified into four types. Follow-up MR images were analyzed to evaluate changes in size, signal intensity, rebleeding, and perilesional adverse reaction of irradiation. A total of 61 cavernous malformations including 17 in type I, 23 in type II, 10 in type III, and 11 in type IV showed usual degradation of blood product in 22 cavernous malformations, no change in shape and signal intensity in 31 cavernous malformations, and eight cavernous malformations with rebleedings in the serial MR images. In these eight cavernous malformations with rebleedings, six occurred in type II and two in type III, but none in type I or IV. Rebleedings were more frequent in type II than in other types. Adverse reaction of irradiation was observed in five of 22 patients treated with gamma knife surgery. Although most cerebral cavernous malformations showed evolution of hemorrhage or no change in size or shape on follow-up MR images, cerebral cavernous malformations represented as mixture of subacute and chronic hemorrhage with hemosiderin rim (type II) have a higher frequency to rebleed than other types of cerebral cavernous malformations. Cerebral cavernous malformations represented as hemosiderin deposition without central core (type IV) have a lower tendency to rebleed than other types and do not need any treatment. Most of the adverse reaction of irradiation after gamma knife surgery around cavernous malformations are transient findings and are considered to be perilesional edema. (K.H)

    The intent of this study is to examine the internal structure of the Bayou Choctaw salt dome utilizing the information obtained from graphical representations of sonar survey data of the internal cavern surfaces. Many of the Bayou Choctaw caverns have been abandoned. Some existing caverns were purchased by the Strategic Petroleum Reserve (SPR) program and have rather convoluted histories and complex cavern geometries. In fact, these caverns are typically poorly documented and are not particularly constructive to this study. Only two Bayou Choctaw caverns, 101 and 102, which were constructed using well-controlled solutioning methods, are well documented. One of these was constructed by the SPR for their use while the other was constructed and traded for another existing cavern. Consequently, compared to the SPR caverns of the West Hackberry and Big Hill domes, it is more difficult to obtain a general impression of the stratigraphy of the dome. Indeed, caverns of Bayou Choctaw show features significantly different than those encountered in the other two SPR facilities. In the number of abandoned caverns, and some of those existing caverns purchased by the SPR, extremely irregular solutioning has occurred. The two SPR constructed caverns suggest that some sections of the caverns may have undergone very regular solutioning to form uniform cylindrical shapes. Although it is not usually productive to speculate, some suggestions that point to the behavior of the Bayou Choctaw dome are examined. Also the primary differences in the Bayou Choctaw dome and the other SPR domes are noted.

    Cavernous hemangioma of the internal auditory canal (IAC) is an extremely rare type of tumor, and only 50 cases have been reported in the literature prior to this study. The aim in this study was to describe the symptomatology, radiological features, and surgical outcomes for patients with cavernous hemangioma of the IAC and to discuss the diagnostic criteria and treatment strategy for the disease. The study included 6 patients with cavernous hemangioma of the IAC. All patients presented with sensorineural hearing loss and tinnitus, and 2 also suffered from vertigo. Five patients reported a history of facial symptoms with hemispasm or palsy: 3 had progressive facial weakness, 1 had a hemispasm, and 1 had a history of recovery from sudden facial paresis. All patients underwent CT and MRI to rule out intracanalicular vestibular schwannomas and facial nerve neuromas. Five patients had their tumors surgically removed, while 1 patient, who did not have facial problems, was followed up with a wait-and-scan approach. All patients had a presurgical diagnosis of cavernous hemangioma of the IAC, which was confirmed pathologically in the 5 patients who underwent surgical removal of the tumor. The translabyrinthine approach was used to remove the tumor in 4 patients, while the middle cranial fossa approach was used in the 1 patient who still had functional hearing. Tumors adhered to cranial nerves VII and/or VIII and were difficult to dissect from nerve sheaths during surgeries. Complete hearing loss occurred in all 5 patients. In 3 patients, the facial nerve could not be separated from the tumor, and primary end-to-end anastomosis was performed. Intact facial nerve preservation was achieved in 2 patients. Patients were followed up for at least 1 year after treatment, and MRI showed no evidence of tumor regrowth. All patients experienced some level of recovery in facial nerve function. Cavernous hemangioma of the IAC can be diagnosed preoperatively through analysis of clinical

    Limited demand and high cost has prevented the construction of hard rock caverns in this country for a number of years. The storage of natural gas in mined caverns may prove technically feasible if the geology of the targeted market area is suitable; and economically feasible if the cost and convenience of service is competitive with alternative available storage methods for peak supply requirements. It is believed that mined cavern storage can provide the advantages of high delivery rates and multiple fill-withdrawal cycles in areas where salt cavern storage is not possible. In this research project, PB-KBB merged advanced mining technologies and gas refrigeration techniques to develop conceptual designs and cost estimates to demonstrate the commercialization potential of the storage of refrigerated natural gas in hard rock caverns. Five regions of the U.S.A. were studied for underground storage development and PB-KBB reviewed the literature to determine if the geology of these regions was suitable for siting hard rock storage caverns. Area gas market conditions in these regions were also studied to determine the need for such storage. Based on an analysis of many factors, a possible site was determined to be in Howard and Montgomery Counties, Maryland. The area has compatible geology and a gas industry infrastructure for the nearby market populous of Baltimore and Washington D.C.. As Gas temperature is lowered, the compressibility of the gas reaches an optimum value. The compressibility of the gas, and the resultant gas density, is a function of temperature and pressure. This relationship can be used to commercial advantage by reducing the size of a storage cavern for a given working volume of natural gas. This study looks at this relationship and and the potential for commercialization of the process in a storage application. A conceptual process design, and cavern design were developed for various operating conditions. Potential site locations were considered

    Thrombosis of the lateral sinus can be classified into nonseptic lateral sinus thrombosis and septic lateral sinus thrombosis. Nonseptic lateral sinus thrombosis differs from septic lateral sinus thrombosis in that it is not associated with ear or sinus infection. Etiologies of these conditions are different and hence the management of these conditions is different. Nonseptic lateral sinus thrombosis requires medical line of management and anticoagulant therapy, where as septic lateral sinus ...

  14. Imaging of paranasal sinuses today; Bildgebung der Nasennebenhoehlen (NNH) in der heutigen Zeit

    CT is accepted as the gold standard for pathological-anatomical evaluation of paranasal sinus disease, CT is especially considered an obligatory part of planning surgical procedures. Indications for paranasal sinus CT include trauma, malignant disease, and chronic sinusitis, which accounts for the major part of examinations. Due to the benign character of the disease and the relatively moderate age of the patients involved, the radiation dose of paranasal sinus CT plays an important role. The use of a low-dose spiral CT technique and the reformation of coronal images out of the axial CT data instead of an additional direct coronal scan allow the effective dose of paranasal sinus CT to be reduced to the order of a chest radiogram. MRI is the preferred imaging modality in malignant disease or complications of inflammatory sinus disease that extend beyond the limits of the paranasal sinuses. The clinical value of other imaging modalities, including plain film radiography, ultrasound, or scintigraphy, is limited to special indications. (orig.)

    The clinical results of photodynamic therapy of maxillary sinusitis have been presented. 0.1%-Methylene Blue aqueous solution in combination with He-Ne laser irradiation (632.8 nm) has been used for treatment of patients with acute and chronic maxillary sinusitis. Efficacy of the photodynamic therapy was estimated with the use of the following criteria: the state of respiration, olfaction, duration of purulent discharge, reconstruction of transport function of ciliary epithelium, etc. The obtained results have shown that the photodynamic therapy is effective in comparison with conservative methods of treatment of the diseases.

    Chronic invasive fungal sinusitis (CIFS) is a rare but potentially aggressive form of invasive fungal disease that occurs in immunocompetent patients. We report a case of CIFS in an otherwise healthy young adult associated with intranasal illicit drug abuse. The patient presented with nonhealing nasal septal and palatal perforations. Biopsy demonstrated invasive Aspergillus flavus requiring surgical debridement and extended intravenous antifungal therapy. Tissue necrosis and ulceration related to intranasal drug use should be recognized as a potential risk factor for invasive fungal sinusitis. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.
