    Full Text Available We report a case of adrenal metastasis from colorectal cancer in a 54-year-old woman. Nine months after resection for advanced rectal carcinoma, a computed tomography scan revealed bilateral adrenal metastasis. The level of serum carcinoembryonic antigen was normal. A bilateral adrenalectomy was performed after chemotherapy. Histopathological examination showed adenocarcinoma, compatible with metastasis from the rectal cancer. Adrenal metastasis should be considered in the patients’ follow-up for colorectal cancer.

    surgery was performed. A new computerized tomography scan showed rapid progression of disease with further enlargement of the adrenal masses and both pulmonary and hepatic metastasis. Needle biopsy was performed but the patient refused further treatment and died before a diagnosis was obtained. The...... immuneohistochemical diagnosis was large B-cell lymphoma. This case should remind clinicians that PAL may be a cause of bilateral adrenal incidentaloma especially if the patient presents with adrenal insufficiency....

    Full Text Available We report a case of synchronous bilateral adrenal metastasis of renal cell carcinoma. The contralateral metastatic adrenal mass was treated by the laparoscopic transperitoneal approach. The renal mass and its huge ipsilateral metastatic adrenal gland were removed en bloc with open procedure. A 54-year-old man presented to our clinic with left-sid renal cell carcinoma synchronously bilateral adrenal metastases. The primary tumor was localized in the upper-mid pole of the kidney. The diagnosis was established preoperatively by computed tomography. The size of the contralateral adrenal mass was 65 x 45 mm, but the ipsilateral metastatic adrenal mass was huge (140 x 65 mm. After all analysis and other scannings for any metastasis, a contralateral lapararoscopic transperitoneal adrenalectomy and a left open nephroadrenalectomy were performed simultaneously. Synchronous bilateral adrenal metastases from primary renal cell carcinoma without another metastasis is very rare. The optimal surgical procedure should be selected according to the metastatic adrenal masses size and the patient%u2019s status.

    Background Bilateral adrenal masses may have aetiologies like hyperplasia and infiltrative lesions, besides tumours. Hyperplastic and infiltrative lesions may have coexisting hypocortisolism. Bilateral tumours are likely to have hereditary/syndromic associations. The data on clinical profile of bilateral adrenal masses are limited. Aims To analyse clinical, biochemical and radiological features, and management outcomes in patients with bilateral adrenal masses. Methods Retrospective analysis of 70 patients with bilateral adrenal masses presenting to a single tertiary care endocrine centre from western India (2002–2015). Results The most common aetiology was pheochromocytoma (40%), followed by tuberculosis (27.1%), primary adrenal lymphoma (PAL) (10%), metastases (5.7%), non-functioning adenomas (4.3%), primary bilateral macronodular adrenal hyperplasia (4.3%), and others (8.6%). Age at presentation was less in patients with pheochromocytoma (33 years) and tuberculosis (41 years) compared with PAL (48 years) and metastases (61 years) (PAI) (95%). The presenting symptoms for PAL were AI (57%) and abdominal pain (43%), whereas all cases of metastasis had abdominal pain. Mean size of adrenal masses was the largest in lymphoma (5.5cm) followed by pheochromocytoma (4.8cm), metastasis (4cm) and tuberculosis (2.1cm) (P<0.001). Biochemically, most patients with pheochromocytoma (92.8%) had catecholamine excess. Hypocortisolism was common in tuberculosis (100%) and PAL (71.4%) and absent with metastases (P<0.001). Conclusion In evaluation of bilateral adrenal masses, age at presentation, presenting symptoms, lesion size, and biochemical features are helpful in delineating varied underlying aetiologies.

  5. Bilateral spontaneous adrenal haemorrhage complicating acute pancreatitis

    International Nuclear Information System (INIS)

    Bilateral adrenal haemorrhage is an event that mandates prompt diagnosis and treatment to prevent primary adrenocortical insufficiency and potential death. Presentation can be non-specific and incidentally diagnosed with imaging alone, primarily CT. We present a case of acute pancreatitis with spontaneous bilateral adrenal haemorrhage and briefly discuss imaging and treatment implications

  6. Scintigraphy of incidentally discovered bilateral adrenal masses

    International Nuclear Information System (INIS)

    The purpose of this study was to determine the patterns of iodine-131 6β-iodomethylnorcholesterol (NP-59) imaging and the correlation with CT-guided adrenal biopsy and follow-up in patients with bilateral adrenal masses. To this end we investigated a consecutive sample of 29 euadrenal patients with bilateral adrenal masses discovered on CT for reasons other than suspected adrenal disease. Adrenal scintigraphy was performed using 1 mCi of NP-59 injected i.v., with gamma camera imaging 5-7 d later. In 13 of the 29 patients bilateral adrenal masses were the result of metastatic involvement from lung carcinoma (5), lymphoma (3), adrenocarcinoma of the colon (3), squamous cell carcinoma of the larynx (1), and anaplastic carcinoma of unknown primary (1). Among these cases the NP-59 scan demonstrated either bilaterally absent tracer accumulation (8, all with bilateral metastases) or marked asymmetry of adrenocortical NP-59 uptake (5). Biopsy of the adrenal demonstrating the least NP-59 uptake documented malignant involvement of that gland in five of five patients. In two patients an adenoma was found simultaneously in one adrenal with a contralateral malignant adrenal mass. In each of these cases, the adenoma demonstrated the greatest NP-59 uptake. In 16 patients diagnosis of adenoma was made on the basis of CT-guided adrenal biopsy of the gland with the greatest NP-59 uptake of the pair (n=4), or adrenalectomy (n=2), or absence of change in the size of the adrenal mass on follow-up CT scanning performed 6 months to 3 years later (n=10).

    Full Text Available Histoplasmosis is a fungal disease that is endemic in Brazil. It may present as chronic pulmonary infection or in disseminated form. Disseminated histoplasmosis frequently affects the adrenal gland; however, unilateral involvement in immunosuppressed patients is the usual presentation. We report a case of an elderly immunocompetent male with history of weight loss, fever and bilateral adrenal mass who was successfully treated with itraconazole.Histoplasmose é uma doença fúngica endêmica no Brasil que pode se apresentar como infecção pulmonar crônica ou na forma disseminada. A histoplasmose disseminada freqüentemente acomete a glândula adrenal; entretanto, ocorre mais em pacientes imunossuprimidos e de forma unilateral. Relatamos um caso de um homem idoso imunocompetente com história de perda de peso, febre e massa adrenal bilateral que foi tratada com itraconazol, com sucesso.

  9. Bilateral adrenal hemorrhage and primary antiphospholipid antibody syndrome

    International Nuclear Information System (INIS)

    Bilateral adrenal hemorrhage is an uncommon entity that is difficult to diagnose given the ambiquity of the clinical signs. Computerized tomography plays a major role in the diagnosis, disclosing enlarged adrenal glands presenting the hyperdense aspect that characterizes this disorders. We present a case of bilateral adrenal hemoorrhage in a patient diagnosed as having primary antiphospholipid antibody syndrome, which is a less common cause of adrenal hemorrhage than those classically reported, such as anticoagulant therapy, sepsis, shock and abdominal injury.

O cão morreu por peritonite séptica aguda, decorrente de ulceração e perfuração intestinal por corpo estranho linear. O neoplasma foi achado incidentalmente durante a necropsia. Macroscopicamente, as adrenais estavam redondas e com volume e aumentados. Ao corte elas eram friáveis, vermelho-amarronzadas, intercaladas por áreas branco-amareladas levemente proeminentes. Histologicamente, extensas áreas do parênquima continham adipócitos bem diferenciados, células hematopoéticas e macrófagos com hemossiderina, achados característicos de mielolipoma adrenal.A case of bilateral adrenal myelolipoma in a 13-year-old female Poodle is reported. Acute septic peritonitis due to intestinal ulceration and perforation caused by a linear foreign body was the cause of death. The adrenal neoplasm was an incidental necropsy finding. The adrenal glands were grossly rounded, enlarged and friable, and had red-brownish parenchyma interwoven by slightly prominent white-yellowish foci. Histologically, the findings of differentiated adipocytes in large areas of the parenchyma, in association to hematopoietic cells and macrophages with hemosiderin were consistent with the diagnosis of adrenal myelolipoma.

  11. Bilateral adrenal cystic neuroblastoma with superior vena cava syndrome and massive intracystic haemorrhage

    International Nuclear Information System (INIS)

    Bilateral cystic adrenal tumours are a rare presentation of neuroblastoma. Intratumoural haemorrhage is a frequent finding in neuroblastoma, but is rarely symptomatic. We present an 11-month-old girl with predominantly cystic bilateral neuroblastomas and distant lymph-node metastasis. Massive intracystic haemorrhage and superior vena cava (SVC) syndrome were ominous prognostic factors, leading to death. Large tumours with intracystic haemorrhage might require a conservative approach. (orig.)

    BACKGROUND Uterine papillary serous carcinoma (UPSC) is a highly malignant form of endometrial cancer with a high propensity for metastases and recurrences even when there is minimal or no myometrial invasion. It usually metastasizes to the pelvis, retroperitoneal lymph nodes, upper abdomen, and peritoneum. However, adrenal metastases from UPSC is extremely rare. Here, we present a case of UPSC with adrenal metastasis that occurred 6 years after the initial diagnosis. CASE REPORT A 60-year-old woman previously diagnosed with uterine papillary serous carcinoma at an outside facility presented in September of 2006 with postmenopausal bleeding. She underwent comprehensive surgical staging with FIGO (International Federation of Gynecology and Obstetrics) stage 2. Post-operatively, the patient was treated with radiation and chemotherapy. The treatment was completed in April of 2007. The patient had no evidence of disease until July 2009 when she was found to have a mass highly suspicious for malignancy. Subsequently, she underwent right upper lobectomy. The morphology of the carcinoma was consistent with UPSC. She refused chemotherapy due to a previous history of chemotherapy-induced neuropathy. The patient was followed up with regular computed tomography (CT) scans. In October 2012 a new right adrenal nodule was seen on CT, which showed intense metabolic uptake on positron emission tomography (PET)/CT scan. The patient underwent right adrenalectomy. Pathology of the surgical specimen was consistent with UPSC. CONCLUSIONS UPSC is an aggressive variant of endometrial cancer associated with high recurrence rate and poor prognoses. Long-term follow-up is needed because there is a possibility of late metastases, as in this case. PMID:27117594

    it is difficult to diagnose because of its nonspecific presentation. This condition frequently occurs in association with an extreme physical stress and may lead to acute adrenal insufficiency or death if not promptly and properly treated. We report a rare case of acute bilateral adrenal hemorrhage with adrenal insufficiency following duodenopancreatectomy for ampulloma in absence of surgical complications. Early diagnosis and corticosteroid replacement with aggressive management of the precipitating pathology are essential to enable a successful outcome. PMID:25945442

    Primary aldosteronism due to unilateral aldosterone-producing adenoma (APA) is a surgically curable form of hypertension. Bilateral APA can also be surgically curable in theory but few successful cases can be found in the literature. It has been reported that even using successful adrenal venous sampling (AVS) via bilateral adrenal central veins, it is extremely difficult to differentiate bilateral APA from bilateral idiopathic hyperaldosteronism (IHA) harbouring computed tomography (CT)-detectable bilateral adrenocortical nodules. We report a case of bilateral APA diagnosed by segmental AVS (S-AVS) and blood sampling via intra-adrenal first-degree tributary veins to localize the sites of intra-adrenal hormone production. A 36-year-old man with marked long-standing hypertension was referred to us with a clinical diagnosis of bilateral APA. He had typical clinical and laboratory profiles of marked hypertension, hypokalaemia, elevated plasma aldosterone concentration (PAC) of 45.1 ng dl(-1) and aldosterone renin activity ratio of 90.2 (ng dl(-1) per ng ml(-1 )h(-1)), which was still high after 50 mg-captopril loading. CT revealed bilateral adrenocortical tumours of 10 and 12 mm in diameter on the right and left sides, respectively. S-AVS confirmed excess aldosterone secretion from a tumour segment vein and suppressed secretion from a non-tumour segment vein bilaterally, leading to the diagnosis of bilateral APA. The patient underwent simultaneous bilateral sparing adrenalectomy. Histopathological analysis of the resected adrenals together with decreased blood pressure and PAC of 5.2 ng dl(-1) confirmed the removal of bilateral APA. S-AVS was reliable to differentiate bilateral APA from IHA by direct evaluation of intra-adrenal hormone production. PMID:26538381

    Full Text Available We are presenting a rare case of bilateral adrenal non-Hodgkin′s lymphoma (NHL that presented as a primary malignancy. An 83-year-old man presented with newly discovered bilateral adrenal incidentalomas, fatigue, and 30 pound weight loss. Of the 116 cases of primary adrenal NHL reported, over half have presented bilaterally and occur with adrenal insufficiency. Therefore, the finding of bilateral adrenal masses requires an urgent work-up of the functional status of the adrenal gland as well as a thorough analysis of the imaging characteristics seen on noncontrast computed tomography (CT in order to maximize patient survival. Adrenal function testing was normal. Repeat CT imaging revealed rapidly growing lesions with high attenuations; both masses >10 HU. Histological examination of core biopsies discovered malignant lymphoma with no known past history of lymphoma. Our case coincides with the literature, which states that a mass with attenuation >10 HU in the adrenal glands has a high risk of malignancy.

  18. Percutaneous interstitial brachytherapy for adrenal metastasis. Technical report

    International Nuclear Information System (INIS)

    We developed and evaluated the feasibility of a brachytherapy technique as a safe and effective treatment for adrenal metastasis. Adapting a paravertebral insertion technique in radiofrequency ablation of adrenal tumors, we developed an interstitial brachytherapy for adrenal metastasis achievable on an outpatient basis. Under local anesthesia and under X-ray CT guidance, brachytherapy applicator needles were percutaneously inserted into the target. A treatment plan was created to eradicate the tumor while preserving normal organs including the spinal cord and kidney. We applied this interstitial brachytherapy technique to two patients: one who developed adrenal metastasis as the third recurrence of uterine cervical cancer after reirradiation, and one who developed metachronous multiple metastases from malignant melanoma. The whole procedure was completed in 2.5 hours. There were no procedure-related or radiation-related early/late complications. 18F-fluorodeoxyglucose positron emission tomography (FDG PET)-CT images at two and three months after treatment showed absence of FDG uptake, and no recurrence of the adrenal tumor was observed for over seven months until expiration, and for six months until the present, respectively. This interventional interstitial brachytherapy procedure may be useful as a safe and eradicative treatment for adrenal metastasis. (author)

    Full Text Available This article focuses on issues related to the identification and investigation of the lymph node metastases with bilateral breast cancer. The presence of metastases in the lymph nodes determines the stage of the disease, and introducing a form of tumor progression, characterizes the course and prognosis for the future in a specific patient. Thus, the identification of possible morphological and immunohistochemical characteristics of the tumor tissue and their comparison with the frequency and severity of regional lymph nodes would help to solve the problem of the identification of prognostic factors and markers associated with the risk of nodal metastasis in bilateral breast cancer. This work is relevant due to the fact that the literature on this issue to date are treated ambiguously, and answers to many questions, unfortunately, no.The authors performed a morphological study of the tumor tissue from 600 patients suffering from unilateral and bilateral breast cancer. To avoid false results were studied only cases corresponding to the histological type of invasive carcinoma of non-specific type. The study found that a greater number and a greater percentage of the affected lymph node metastases were observed in patients with bilaterally synchronous tumors. The patients of this group of metastatic lymph nodes was detected more frequently in the presence of infiltrative component of three or more types of structures with the presence of these discrete groups of tumor cells, and the observed maximum degree of inflammatory infiltration of the tumor stroma. In the group of patients with unilateral breast cancer nodal metastasis often detects when triple negative molecular genetic type of the lesion, with large amounts of tumor site, in the presence of infiltrative component of three or more types of structures with the obligatory presence of these microalveolar structures and discretely spaced groups of tumor cells and the highest severity of

    2005-07-01

    Full Text Available Abstract Background Metastases from hepatocellular carcinoma (HCC can be found in the lung and adrenal gland. We report case of a patient who presented with adrenal metastasis as the first clinical manifestation of HCC. Case presentation A patient was referred for surgical treatment for a tumor in retro-peritoneal space. The computerized tomography (CT scan revealed a mass originating from the left adrenal gland. The patient underwent left adrenalectomy and the exploration of abdominal cavity did not reveal any other palpable lesions. Histologically, the resected lesion was a poorly differentiated metastatic tumor from HCC. Seven months later patient was readmitted complaining of cachexia, icterus, and significant weight loss. CT scan revealed hyperdense lesions of the liver Conclusion HCC may have atypical presentations like in present case. Fine needle aspiration/tru-cut® biopsy might be useful in the investigation of an accidentally discovered adrenal mass regardless of the size and can lead to the detection of a primary tumor.

  1. Differential diagnosis between nonhyperfunctioning adenoma and adrenal metastasis on adrenocortical scintigraphy

    International Nuclear Information System (INIS)

    Adrenocortical scintigraphy using I-131-adosterol was performed in six cases of nonhyperfunctioning adenoma incidentally discovered on CT scans and four cases of adrenal metastasis. In all six cases of nonhyperfunctioning adenoma, there was increased uptake of the I-131-adosterol on the side of the adrenal mass discovered on CT. In three of four cases of adrenal metastasis, there was no uptake of the I-131 adosterol on the side of the mass detected on CT. Uptake was symmetrical in one case of adrenal metastasis. Adrenocortical scintigraphy is able to differentiate nonhyperfunctioning adenoma from adrenal metastasis in recognition of increased uptake of I-131-adosterol on the side of the adrenal mass discovered on CT scans.

    2008-01-01

    BACKGROUND: Although the treatment of extrahepatic metastases from primary liver tumors is essentially palliative, solitary metastasis from such tumors offers a possibility of cure by surgical resection. The adrenal gland is an uncommon site for metastasis from primary liver tumors. METHOD: We report two cases of adrenalectomy for solitary adrenal metastasis: one from intrahepatic cholangiocarcinoma and the other from hepatocellular carcinoma. RESULTS: The patient with intrahepatic cholangiocar-cinoma had a synchronous adrenal metastasis and underwent simultaneous liver resection and adrenalectomy. However, he developed recurrent disease 17 months following surgery for which he is presently on palliative chemotherapy. The other patient underwent adrenalectomy for adrenal metastasis 3 months following liver transplantation for hepatocellular carcinoma. He is presently alive and disease-free 27 months after adrenalectomy. CONCLUSION: Carefully selected patients with solitary metastasis from primary liver tumors may be considered for resection.

    2016-01-01

    We report the case of a 39-year-old man with bilateral adrenal haemorrhage. The diagnosis is rarely primarily made with imaging alone. Our patient had a previous history of a stroke six years prior to this episode. We evoke the possibility that long-term daily cannabis use could be the underlying cause of the patient's vascular pathologies. After thorough review of existing literature, this link was found to be probable. Cannabis is the most consumed recreational drug in the world, and this tendency is ever-increasing. Serious complications other than psychiatric resulting from consumption are reported with increasing frequency. Neurological, cerebrovascular, cardiovascular and respiratory complications have been observed. It is thus important to remain vigilant when patients are hospitalised notably through the emergency department, in order to obtain a complete anamnesis, optimise screening, and to adapt the treatment of these patients.

    The aim of this study was to evaluate the adrenal FDG uptake in patients with lung cancer, and to assess the diagnostic performance. The aim of this study was to evaluate the adrenal FDG uptake in patients with lung cancer, and to assess the diagnostic performance of FDG PET in detecting adrenal metastasis. A total of 117 healthy subjects who underwent FDG PET/CT for cancer screening (M: F=74: 43, 50.011.3 yr) and 171 lung cancer patients who underwent FDG PET/CT for staging (M: F = 104: 67, age; 61.8 10.4 yr) were. The diagnosis of adrenal metastasis was confirmed by histology or radiologic follow-up. Maximal SUV of healthy subjects were 1.66 0.21 and 1.86 0.30 in right and left adrenal gland, and 2.77 0.37 in the liver. However, lung cancer patients had maximal SUV of 1.68 0.47, 1.64 0.39, and 2.15 0.49, respectively. SUV of liver was higher in healthy subjects group (p < 0.001). The ratio of adrenal gland to liver (AL ratio) in lung cancer were higher than that of normal subjects (0.61 0.10 vs. 0.78 0.14 in right adrenal gland, 0.68 0.12 vs. 0.78 0.14 in left adrenal gland; both of them: p < 0.001). From 24 adrenal masses of 22 lung cancer patients, 15 adrenal masses were proven as adrenal metastasis and the others were diagnosed as adrenal adenoma. We defined normal value of adrenal gland as mean + 2SD. The maximal SUV and AL ratio of lung cancer patients were 2.52 and 1.06, respectively. Both of them had a same sensitivity (86.7%) and specificity (88.9%). With ROC curves analysis, cut-off value of maxSUV and AL ratio on adrenal mass were 3.55 (area under curve = 0.900) and 1.21(area = 0.852). Sensitivity and specificity of maxSUV were 86.7% and 100% and AL ratio were 80.0% and 88.9%. Lung cancer patients had elevated adrenal FDG uptake than that of normal healthy subjects. Adrenal mass with maximal SUV over 3.55 could be considered as metastatic lesion in lung cancer patients

  6. Analysis of the ultrasonic image of adrenal metastasis in primary lung cancer

    International Nuclear Information System (INIS)

    Objective: To investigate the ultrasonic image of adrenal metastasis in primary lung cancer. Methods: The ultrasonic imaging characteristics of fourteen patients with adrenal metastasis in primary lung cancer were retrospectively reviewed. In all the cases, US-guided percutaneous biopsy was performed for pathological evaluation during the clinical diagnosis. Results and Conclusion: In ultrasonography the adrenal metastatic tumors were manifested as solitary in all the cases, well-defined in 10 cases, irregularly shaped in 10 cases, hypoechoic in 13 cases, and 1 case showed cystoid structure in the tumor. The maximum diameter of the tumor was 3.0-15.3 cm. 9 cases were metastatic adenocarcinoma. The sonographic appearance of adrenal metastasis in primary lung cancer has its characteristics. Ultrasonography can find adrenal metastalic tumors easily and contribute to diagnosis. (authors)

    A biopsy-proven fat-containing metastasis to the adrenal gland in a patient with hepatocellular carcinoma demonstrated low density on nonenhanced CT, heterogeneity on contrast-enhanced CT, and marked signal loss on opposed-phase gradient-echo MRI, mimicking an adrenal adenoma. However, the mass was not present on older studies and showed increased FDG uptake on PET. The possibility of a fat-containing metastasis should be considered for an apparent adrenal adenoma in a patient with a primary hepatocellular carcinoma. PMID:22614216

    Full Text Available Introduction: Late bilateral renal metastasis of chori-ocarcinoma is a rare condition. Herein we report a case of late renal metastasis of choriocarcinoma."nCase Presentation: A 28 years old woman presented with gross hematuria since three months ago. A mo-bile palpable mass in her right flank was detected. She was not pregnant but had a history of abortion at six weeks of gestation in seven years age. Her gyneco-logic examination was normal. She had severe anemia (Hb=7.2, elevated ESR (52 with normal renal and liver function testes. Ultrasonography showed bilat-eral large kidney masses by solid-cystic components, with predominant solid parts. Bilateral lobulated het-erogeneous renal masses were found at non-enhancing axial CT-Scan, with notable enhancement of solid parts after administration of contrast agent. Angiography revealed bilateral hypovascular renal masses. Right radical nephrectomy performed for the patient and pathology reported choriocarcinoma of kidney. Finally, she was referred for chemotherapy of contralateral renal mass, but she delayed that for three months. She died following a seizure attack and cardiopulmonary arrest without response to prompt cardio-pulmonary resuscitation. Autopsy not permit-ted by relevants. "nConclusion: Late metastases of choriocarcinoma may appear in kidney or brain after a long time following the primary source of malignancy, when the primary lesion has disappeared.

    We describe a case of a 62-year-old woman with a history of chronic obstructive pulmonary disease and gastro-oesophageal reflux disease who presented to the emergency department with left lower quadrant abdominal pain, flank pain with nausea and no history of preceding trauma. The patient had finished a course of azithromycin and oral methylprednisolone 1 day prior to presentation. Abdominal and pelvic CT scan identified changes suggestive of bilateral adrenal haemorrhage. The patient did not show signs of acute adrenal insufficiency but was started on steroid replacement therapy because of concerns about possible disease progression. All recognised causes of adrenal haemorrhage were excluded suggesting this was a case of spontaneous idiopathic bilateral adrenal haemorrhage, a rarely reported phenomenon in the literature. The patient was discharged after clinical improvement following 6 days in hospital, taking oral steroid replacement. PMID:27166002

    Full Text Available Abstract Background Cryptococcus species usually affect the central nervous system and lungs in immunocompromised hosts. Although the adrenal glands can be involved in disseminated cryptococcosis, primary adrenal insufficiency caused by the fungal infection is uncommon. Case presentation We present a case of primary adrenal insufficiency with bilateral adrenal masses and liver invasion in a 43-year-old man with mild type 2 diabetes mellitus. Cryptococcosis was diagnosed by fine-needle aspiration biopsy of the liver mass. The serum cryptococcal antigen titer was elevated to 1:256. After 6 months of antifungal therapy with fluconazole and amphotericin B, the size of the liver mass was decreased, but no significant changes were observed in the bilateral adrenal masses and the serum cryptococcal antigen titer remained elevated at 1:128. To control the cryptococcosis, a laparoscopic left adrenalectomy was performed, followed by antifungal therapy. After the unilateral adrenalectomy, the size of the remaining right adrenal mass was reduced and the serum cryptococcal antigen titer declined to 1:4. Conclusions This is the first report describing adrenal cryptococcosis with adrenal insufficiency and liver invasion without central nervous system involvement. Adrenal cryptococcosis should be considered in the differential diagnosis for patients with bilateral adrenal masses with primary adrenal deficiency. Unilateral adrenalectomy was quite effective in controlling the cryptococcosis in this case. Even in patients with bilateral adrenal cryptococcosis, unilateral adrenalectomy should be an option for treatment of disseminated cryptococcosis.

  16. Benign adrenal hypertrophy versus metastasis: value of MRI

    International Nuclear Information System (INIS)

    On the basis of a case report, the authors stress the value of MRI in the assessment of an adrenal mass discovered on CT in patients with lung cancer. The presence of a hypersignal on the weighted T2 sequences is observed more frequently in the case of metastases, while a signal, iso-intense with the liver and the muscles, is generally observed with adenomas. This approach may allow a reduction in the indications for adrenal aspiration biopsy in the context of the pre-operative staging of these patients

    INTRODUCTION: Bilateral adrenal haemorrhage is a rare cause of adrenal failure. Clinical features are non-specific and therefore a high index of suspicion must be maintained in patients at risk. Predisposing factors include infection, malignancy and the post-operative state. CASE PRESENTATION: We report the case of a patient who underwent a left hemicolectomy with primary anastomosis and formation of a defunctioning loop ileostomy for an obstructing colon carcinoma at the splenic flexure. En-bloc splenectomy was performed to ensure an oncologic resection. The patient developed a purulent abdominal collection post-operatively and became septic with hypotension and pyrexia. This precipitated acute bilateral adrenal haemorrhage with consequent adrenal insufficiency. Clinical suspicion was confirmed by radiological findings and a co-syntropin test. Following drainage of the collection, antibiotic therapy and corticosteroid replacement, the patient made an excellent recovery. CONCLUSION: This case highlights the importance of prompt diagnosis and treatment of adrenal failure. In their absence, this condition can rapidly lead to death of the patient.

    Full Text Available We report a rare presentation of an initially misdiagnosed case of a pseudotumor, which on histopathology was diagnosed as bilateral breast metastases of lobular carcinoma involving multiple extraocular muscles. A 61-year-old lady presented with external ophthalmoplegia and diplopia. Incisional biopsy was performed using a lid crease approach and the patient received radiotherapy and hormonal therapy. Following prolonged hormonal therapy, complete remission was achieved, with improvement in ocular motility and resolution of diplopia, about 18 months after the initial presentation. Multiple extraocular muscle involvement by breast carcinoma metastasis is very rare and should be considered in the differential diagnosis, especially in patients with a prior history of breast carcinoma.

    Full Text Available Abstract Introduction Many fetal malformations can occur because of maternal diabetes. However, ambiguous genital organs have never been reported as an associated finding in the literature. This is the first report of associated ambiguous genital organ and bilateral adrenal hyperplasia in a case of diabetic fetopathy. Case presentation A 19-year-old Thai primigravida with familial history of diabetes mellitus (DM was diagnosed as having gestational DM type 2, based on 100 g oral glucose tolerance test, and was poorly controlled with insulin injections. Delayed targeted ultrasonography at 28 weeks gestation revealed multiple fetal anomalies. The woman underwent low transverse cesarean section at 30 weeks gestation due to preterm labor and transverse lie. The newborn with ambiguous genitalia was delivered but expired after birth. Autopsy findings revealed alobar holoprosencephaly, a prominent forehead, hypotelorism, an absent nose, absent bilateral ears, median cleft lip and palate, preaxial polydactyly of the right hand, accessory spleens, single umbilical artery, markedly enlarged adrenal glands and ambiguous external genitalia The subsequent fetal chromosomal study revealed 46,XX. Conclusion We describe a case of diabetic fetopathy with classic facial malformation and preaxial hallucal polydactyly which has been proposed as a marker of diabetic embryopathy. Bilateral adrenal hyperplasia with ambiguous genitalia, an uncommon associated anomaly, was also identified. It is controversial whether adrenal hyperplasia can be a novel feature of diabetic fetopathy or just a coincidental finding. Further observation and adequate investigation are needed in such cases.

  1. Sporadic bilateral adrenal medullary hyperplasia: apparent false positive MIBG scan and expected MRI findings

    International Nuclear Information System (INIS)

    Adrenal medullary hyperplasia is a rare cause of clinical symptoms and biochemical findings identical to pheochromocytoma occurring mostly in multiple endocrine neoplasia patients. The scenario of positive MIBG scan, but no focal lesion found on CT and MRI led to diagnostic and management difficulties. Like pheochromocytoma, surgical excision can lead to clinical and biochemical recovery. We report this unusual case of sporadic bilateral adrenal medullary hyperplasia, with hypertension and biochemical abnormalities alleviated after surgical adrenalectomy. Based on T2 values reported in literature, high signal focal lesions may not appear on T2-weighted MRI images until development of frank pheochromocytoma. MIBG scan remains the most sensitive imaging modality for this condition

  2. Differentiation of adrenal tumors in patients with hepatocellular carcinoma: Adrenal adenoma versus metastasis

    International Nuclear Information System (INIS)

    Objective: To investigate whether computed tomography (CT) attenuation test for differential diagnosis of adrenal nodule is applicable in patients with hepatocellular carcinoma (HCC) which shows similar image characteristics to adrenal adenoma. Materials and methods: This retrospective study was approved by our institutional review board, and the requirement for informed consent from study patients was waived. Searching picture archiving and communication system, we identified 3678 patients with HCC who underwent upper abdominal unenhanced CT scans between April 2002 and March 2010, and 114 adrenal nodules (39 adenomas and 75 metastases) were included for analysis. Ten nodules were confirmed pathologically while 104 had imaging diagnosis (enlarged or emerged during the study period). Size, CT number, and the internal characteristics of the lesions were recorded. Results: Mean CT numbers of adrenal adenomas were significantly lower than those of metastases (P < 0.0001, t-test) on unenhanced CT. Thresholds of 17 and 33 Hounsfield units (HU) provided the following sensitivity, specificity, and accuracy: 46.2%, 100%, and 81.6% at 17 HU, and 94.9%, 89.3%, and 91.2% at 33 HU, respectively. The area under receiver operating characteristic curve for the CT number test was 0.96. Metastases were significantly larger than adrenal adenoma (P = 0.009, t-test). However, the accuracy of testing using mass size was 64.0% at most. All adenomas and metastases were depicted as homogeneous masses with the exception of two metastases that presented as heterogeneous masses (necrotic or lipomatous). Conclusion: Adrenal adenomas can be differentiated from HCC metastases using CT number on unenhanced CT

  8. First-pass perfusion computed tomography: Initial experience in differentiating adrenal adenoma from metastasis

    International Nuclear Information System (INIS)

    Objective: To differentiate adrenal adenoma from metastasis in patients using perfusion computed tomography (PCT) imaging. Methods: Thirty-two patients with adrenal masses underwent first-pass PCT imaging. Of these patients, twenty-one were diagnosed with adrenal adenoma, and the others with metastases. Perfusion maps of blood volume (BV), blood flow (BF), mean transit time (MTT) and permeability surface-area production (PS) were generated with an Advantage Windows workstation using the CT perfusion 3.0 software (General Electric Medical Systems, Milwaukee, WI). Histopathologic sections immunostained for CD34 were quantitatively evaluated for microvessel density (MVD). Results: The perfusion parameters such as BV, BF and PS were statistically significant different between the two groups, with adenomas showing higher mean BV (12.18 versus 3.86), BF (97.51 versus 45.99) and PS (21.73 versus 10.93) compared with metastases (p < 0.05). For BV, a cutoff point of 7.30 was found to have a sensitivity of 95.2% and a specificity of 100% to differentiate between adenoma and metastasis. The sensitivity and specificity were 81.0 and 80.0%, respectively, for BF with a cutoff point of 71.96; and 85.7 and 86.7%, respectively, for PS with a cutoff point of 12.70 to differentiate adenoma and metastasis. A comparison of MVD counts from adenomas with those from metastases showed a significant difference (p < 0.05). However, no significant differences were observed in the four perfusion parameters and MVD between lipid rich and lipid poor adenomas. Conclusion: PCT may be useful for evaluating the neovascularization of adrenal masses and differentiating adenoma from metastasis on the basis of PCT parameters. Adenomas show higher BV, BF and PS compared with metastases. According our data, the optimal threshold BV is 7.30, resulting in a sensitivity of 95.2% and a specificity of 100% for the differentiation of adenoma from metastasis. Adrenal adenomas have similar hemodynamic profiles

    Summary Objective To evaluate the outcomes and timing of intervention for adrenal sparing surgery in patients left with a solitary adrenal remnant after bilateral adrenal surgeries. Subjects/Patients and Methods Patients were included in the study if they had undergone bilateral adrenal surgery as a treatment for pheochromocytoma and were left with a solitary adrenal remnant. Perioperative, functional, and oncologic outcomes were evaluated on 21 patients that met the inclusion criteria. Results There was minimal perioperative morbidity and no perioperative mortality. After a median follow up of 21 months (range 3–143) there were two cases of persistent disease. Ten patients (48%) required steroid supplementation upon discharge with 4 subsequently discontinuing steroid supplementation. Patients were more likely to require steroid supplementation postoperatively if they underwent simultaneous adrenalectomy and contralateral partial adrenalectomy, rather than staged procedures (86% versus 40%, p=0.02). Additionally, patients who underwent surgery for tumors greater than 4 cm were more likely to require long-term steroids than patients who underwent surgery for lesions less than 4 cm (75% versus 18%, p=0.05). Conclusions Patients left with a solitary adrenal remnant after bilateral adrenal surgery have low surgical morbidity, reasonable functional outcomes and low rates of recurrence at an intermediate follow-up period. A staged approach may decrease the immediate postoperative need for steroids, and intervention before the largest tumor reaches 4 cm may decrease the rate of long-term steroid dependence.

    2014-01-01

    Full Text Available Introduction. Isolated adrenal metastases of invasive ductal breast carcinoma are extremely rare. We report a case with isolated left adrenal metastases, verified three years after diagnosed breast carcinoma. Case Outline. A 58-year-old female patient with a right breast tumor, clinically staged as IIIA (T2N2M0 started neoadjuvant anthracycline chemotherapy after biopsy which revealed invasive ductal breast carcinoma. Immunohistochemical findings of tumor biopsy showed hormonal steroid receptors for estrogen and progesterone negative, and human epidermal growth factor receptor 2 (HER2 positive. After 4 cycles of chemotherapy and partial tumor regression the patient underwent radical mastectomy. Definite histopathological analysis confirmed the diagnosis of invasive ductal carcinoma. The patient continued treatment with adjuvant chemotherapy to cumulative dose of anthracyclines, postoperative radiotherapy and adjuvant trastuzumab for one year. Three years later abdominal computerized tomography showed tumor in the left adrenal gland as the only metastatic site. Left adrenalectomy was performed and histopathological finding confirmed breast cancer metastases. Postoperatively, the patient received 6 cycles of docetaxel with trastuzumab and continued trastuzumab until disease progression. One year after left adrenalectomy control abdominal computerized tomography showed a right adrenal tumor with retroperitoneal lymphadenopathy. Treatment with capecitabine was continued for one year, but eventually she developed brain metastasis causing lethal outcome. Conclusion. In order to better understand metastatic pathways of invasive ductal breast carcinoma, publications of individual patient cases diagnosed with rare metastatic sites should be encouraged. This might improve our understanding of metastatic behavior of breast cancer and stimulate further clinical research.

    We have evaluated characteristics of adrenal masses incidentally observed in nonenhanced F-18 FDG PET/CT of the oncologic patients and the diagnostic ability of F-18 FDG PET/CT to differentiate malignant from benign adrenal masses. Between Mar 2005 and Aug 2008, 75 oncologic patients (46 men, 29 women; mean age, 60.8{+-}10.2 years; range, 35-87 years) with 89 adrenal masses incidentally found in PET/CT were enrolled in this study. For quantitative analysis, size (cm), Hounsfield unit (HU), maximum standardized uptake value (SUVmax), SUVratio of all 89 adrenal masses were measured. SUVmax of the adrenal mass divided by SUVliver, which is SUVmax of the segment 8, was defined as SUVratio. The final diagnosis of adrenal masses was based on pathologic confirmation, radiologic evaluation (HU<0 : benign), and clinical decision. Size, HU, SUVmax, and SUVratio were all significantly different between benign and malignant adrenal masses.(P < 0.05) And, SUVratio was the most accurate parameter. A cut-off value of 1.0 for SUVratio provided 90.9% sensitivity and 75.6% specificity. In small adrenal masses (1.5 cm or less), only SUVratio had statistically significant difference between benign and malignant adrenal masses. Similarly a cut-off value of 1.0 for SUVratio provided 80.0% sensitivity and 86.4% specificity. F-18 FDG PET/CT can offer more accurate information with quantitative analysis in differentiating malignant from benign adrenal masses incidentally observed in oncologic patients, compared to nonenhanced CT.

    Long-term consequences of cortisol excess are frequent despite appropriate treatment after cure of Cushing's syndrome. This might be due to diagnostic delay, often difficult to reduce in rare diseases. The identification of a genetic predisposing factor might help to improve early diagnosis by familial screening. Primary bilateral macronodular adrenal hyperplasia (PBMAH) is a rare cause of Cushing's syndrome. Hypercortisolism in PBMAH is most often diagnosed between the fifth and sixth decades of life. The bilateral nature of the adrenocortical tumors and the occurrence of rare clear familial forms suggest a genetic origin. Indeed, a limited subset of PBMAH can be observed as part of multiple tumors syndromes due to alterations of the APC, Menin or Fumarate Hydratase genes. Rare variants of the phosphodiesterases PDE11A have been associated with PBMAH. The recent identification of ARMC5 germline alterations in 25-50% of PBMAH patients without obvious familial history or associated tumors opens new perspectives. ARMC5 alterations follow the model of a tumor suppressor gene: a first germline inactivating mutation of this 16p located gene is followed by a somatic secondary hit on the other allele (inactivating mutation or allelic loss). Functional studies demonstrate that ARMC5 controls apoptosis and steroid synthesis. The phenotype of index cases patients with the mutation seems more severe than the one of WT index cases. However, phenotype variability within a family is often observed. This review summarizes the genetics of PBMAH, focusing on ARMC5, which offer new perspectives for early diagnosis of Cushing's syndrome. PMID:26264719

    Full Text Available Bilateral breast cancer is a rare event accounting for 2-5% of all breast malignancies. A second tumor in contralateral breast may be either synchronous or metachronous lesion. Synchronous bilateral invasive ductal carcinoma is known but medullary carcinoma is rare. The etiology of bilateral breast cancer is uncertain and prognosis in these cases once thought to be poor but recent data suggest a similar survival compared to unilateral disease. We report a case of triple negative synchronous bilateral medullary carcinoma in a 38-year-old female who presented with lump in both the breasts for three months. Multidetector computed tomography breast scan revealed bilateral heterogeneously enhancing well-defined lesion in both the breasts. Fine needle aspiration cytology from both the breast lump was suggestive of malignancy. Patient underwent bilateral modified radical mastectomy with axillary clearance in a single sitting. Histopathology showed synchronous bilateral medullary carcinoma of breast with ER, PR and HER- 2/ neu negativity. Patient was treated with chemoradiation and she is on regular follow up for one year without any recurrence or metastasis.

    The authors review the main findings of primary adrenal lymphoma on abdominal and brain computed tomography (CT) scans and brain magnetic resonance imaging (MRI), and report a rare case of a 72-year-old male patient with deterioration in mental status progressing from recent memory loss to disorientation and ultimately dementia in a period of two months. The patient was investigated using imaging methods including brain (without intravenous administration of iodinated contrast media), chest and abdomen (pre and post intravenous administration of iodinated contrast media) CT scans and brain MRI (pre and post intravenous administration of gadolinium). Brain CT scan showed slightly hyperdense nodules adjacent to the lateral ventricles. No gross abnormalities were seen on the chest CT scan. CT of the abdomen showed solid nodules on both adrenals. Brain MRI showed diffuse nodular enhancement of the ependyma of the fourth ventricle, third ventricle, frontal and temporal horns, atria and body of the lateral ventricles. Definitive diagnosis was made by immunohistochemical study of the biopsed adrenal. After a comprehensive review of the literature the authors concluded that CT and MRI are essential methods for the detection and accurate evaluation of primary adrenal lymphomas, particularly when there is involvement of the central nervous system. MRI is more sensitive in the detection of extracerebral lesions in the epidural and subdural spaces, especially after intravenous administration of gadolinium. (author)

    A 14-year-old female with classical congenital adrenal hyperplasia because of 21-hydroxylase deficiency underwent bilateral adrenalectomy at 6 years of age as a result of poor hormonal control. Because the patient was adrenalectomized, extra adrenal androgen production was suspected. Imaging studies including pelvic ultrasound and pelvic magnetic resonance imaging (MRI) were obtained to evaluate for adrenal rest tumors of the ovaries. Abdominal MRI was obtained to evaluate for residual adrenal tissue. A cystic lesion arising from her right ovary suspicious for ovarian neoplasm was noted on pelvic MRI. Right salpingo-oophorectomy was performed and histopathological examination revealed ovarian serous adenocarcinoma, low-grade, and well-differentiated. Tumor marker CA-125 was elevated and additional ovarian cancer staging workup confirmed stage IIIC due to one lymph node positive for carcinoma. The patient then developed a large left ovarian cyst, which led to a complete total abdominal hysterectomy and removal of the left ovary and fallopian tube. Pathology confirmed ovarian serous adenocarcinoma with microscopic focus of carcinoma in the left ovary. After numerous complications, the patient responded well to chemotherapy, CA-125 levels fell and no evidence of carcinoma was observed on subsequent imaging. To our knowledge, this is the first reported case of an ovarian serous adenocarcinoma in a patient with CAH. Although rare, we propose that the ovaries were the origin of androgen production and not residual adrenal tissue. The relationship between CAH and ovarian carcinomas has yet to be established, but further evaluation is needed given the poor survival rate of high-grade serous ovarian carcinoma. PMID:25427061

    Full Text Available Synchronous bilateral renal cell carcinoma occurs in 1.4 % of cases. The probability of bilateral adrenal metastases from renal cell carcinoma is less than 0.5 %. The clinical observation presents a case of synchronous bilateral renal cell carcinoma and simultaneous metastatic involvement of both adrenal glands. A 55‑year-old male patient was adm tted with the signs of hematuria and anemia to the Unit of Urology, Clinic of General Surgery, Siberian State Medical University. He was found to have synchronous bilateral renal cell carcinoma and simultaneous bilateral adrenal involvement. Sequential surgical treatment – radical nephrectomy (with adrenal gland removal on the right side and, after 3 months, adrenalectomy and kidney resection on the left side were performed. All the organs removed displayed tumors that proved to be renal cell carcinomas (a clear cell variant. There were lymph node metastases in the right-sided renal portal. Postoperatively, the investigators performed hormone replacement therapy for adrenal insufficiency, an immunotherapy cycle, three cycles of targeted therapy withsorafenib and sunitinib (at an interval of 0.5–2 years, and insulin therapy for new-onset diabetes mellitus. The duration of a follow-up was 6.2 years. When describing the case, the patient was alive and showed a generalized tumorous process with extensive tumor involvement of the solitary kidney. Sunitinib therapy was used.

    Bilateral adrenalectomy is currently the only available treatment for adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome (ectopic ACTH syndrome) that is refractory to pharmacologic therapy. We describe two patients with refractory ectopic ACTH syndrome who were treated with CT-guided percutaneous microwave ablation of both hyperplastic adrenal glands in a single session: One was not a surgical candidate, and the other had undergone unsuccessful surgery. Following the procedure, both patients achieved substantial decreases in serum cortisol, symptomatic improvement, and decreased anti-hypertensive medication requirements.

  4. 131I-19-iodocholesterol adrenal scanning in Cushing's syndrome

    International Nuclear Information System (INIS)

    7 patients were investigated: 2 bilateral hyperplasia due to pituitary ACTH excess showed bilateral adrenal activity. 1 post-surgical remnant with recurrent Cushing's syndrome was detected. 1 adenoma showed unilateral intense activity and absent activity in the controlateral gland, even after ACTH treatment. 2 carcinomas were weakly imaged. In 1 case, hepatic metastasis showed 131I-19-iodocholesterol uptake. Adrenal imaging with 131I-19-iodocholesterol is not a good procedure for assessing hormonal function. It is a valuable and safe tool in the localization and diagnosis of adrenal lesions causing Cushing's syndrome, perhaps better than radiologic procedures. Radiation dosimetry is acceptable

    Full Text Available Abstract Background Breast cancer is usually associated with metastases to lungs, bones and liver. Breast carcinoma metastasizing to the gallbladder is very rare. Case presentation A 59-year-old woman presented with bilateral synchronous breast lesions. A palpable, retroareolar solid lesion of diameter equal to 5 cm was present in the right breast, and a newly developed, non-palpable lesion with microcalcifications (diameter equal to 0.7 cm was present in the upper outer quadrant of the left breast. Modified radical mastectomy was performed on the right breast and lumpectomy after hook-wire localization was performed on the left breast, combined with lymph node dissection in both sides. The pathological examination revealed invasive lobular carcinoma grade II in the right breast and invasive ductal carcinoma grade I in the left breast. Chemotherapy, radiation therapy, trastuzumab and letrozole were appropriately administered. At her 18-month follow-up, the patient was free of symptoms; the imaging tests (chest CT, abdominal U/S, bone scan, biochemical tests, blood cell count and tumor markers were also normal. At the 20th month after surgery however, the patient developed symptoms of cholecystitis and underwent cholecystectomy. The histopathological examination revealed metastasis of the lobular carcinoma to the gallbladder. Conclusion This extremely rare case confirms on a single patient the results of large series having demonstrated the preferential metastasis of lobular breast cancer to the gallbladder. Symptoms of cholecystitis should not be neglected in such patients, as they might indicate metastasis to the gallbladder.

    Adrenocorticotropin-independent adrenal hyperplasias are rare diseases, which are classified into macronodular (>1 cm) and micronodular (≤1 cm) hyperplasia. Micronodular adrenal hyperplasia is subdivided into primary pigmented adrenocortical disease and a limited or nonpigmented form 'micronodular adrenocortical disease (MAD)', although considerable morphological and genetic overlap is observed between the 2 groups. We present an unusual case of a 44-month-old girl who was diagnosed with Cushing syndrome due to MAD. She had presented with spotty pigmentation on her oral mucosa, lips and conjunctivae and was diagnosed with multiple bone tumors in her femur, pelvis and skull base at the age of 8 years. Her bone tumor biopsies were compatible with osteoblastoma. This case highlights the importance of verifying the clinicopathologic correlation in Cushing syndrome and careful follow-up and screening for associated diseases. PMID:27104180

It is possible to diagnose various diseases of the adrenal glands not only structural but also functional abnormalities. In patients with adrenogenital syndromes, we are able to demonstrate hyperplasia of the adrenal glands, and in patients with aldosteronism or Cushing's syndrome differential diagnosis between bilateral hyperplasia and functional adenoma of the adrenal gland can be made.

  10. Computed tomography in the diagnosis of adrenal disease

    International Nuclear Information System (INIS)

    From June 1977 through June 1980, sixty-one patients who were suspected to have adrenal diseases were examined with a CT scanner at Tokyo Women's Medical College. They consist of twenty five primary hyperaldosteronism, eight Cushing's syndrome, twenty pheochromocytoma and eight other adrenal masses. Ten patients were unexpectedly found to have adrenal lesion or mass simulating an adrenal tumor on CT performed for other reasons. CT findings were reviewed and correlated with surgical findings, postmortem studies and with results of other diagnostic modalities. 1. Primary hyperaldosteronism. Fifteen of twenty-five patients underwent surgery. Thirteen were pathologically proved to have aldosteronoma and two hyperplasia. Ten of thirteen patients with aldosteronoma were correctly diagnosed by CT scan. 2. Cushing's syndrome. Unilateral adenoma was correctly diagnosed preoperatively by CT scan on two surgically proved cases. CT showed marked enlargement of the adrenal gland with multiple nodules measuring less than 2 cm in diameter in the patient with nodular hyperplasia. Four patients were found to have normal-appearing adrenals with CT scan. 3. Pheochromocytoma. Three adrenal and one juxta-adrenal pheochromocytomas were detected by CT scan. Pheochromocytoma was considered as very unlikely on the basis of CT scan as well as further clinical investigation in sixteen patients. The value of CT scan for localization of extraadrenal pheochromocytoma remains established. 4. Miscellaneous adrenal disease and extra-adrenal masses simulating adrenal lesions. Two primary carcinoma, two bilateral metastasis, two adrenal neuroblastoma and a cyst were detected by CT scan. In cases with a huge mass, however, the origin and histologic diagnosis could not always be determined by CT scan. (author)

    2016-12-01

    Full Text Available 21-hydroxylase deficiency (21-OHD caused congenital adrenal hyperplasia (CAH is a group of autosomal recessive genetic disorders resulting from mutations in genes involved with cortisol (CO synthesis in the adrenal glands. Testicular adrenal rest tumors (TARTs are rarely the presenting symptoms of CAH. Here, we describe a case of simple virilizing CAH with TARTs, in a 15-year-old boy. The patient showed physical signs of precocious puberty. The levels of blood adrenocorticotropic hormone (ACTH, urinary 17-ketone steroids (17-KS, dehydroepiandrosterone sulfate (DHEA-S, and serum progesterone (PRGE were elevated, whereas those of follicle-stimulating hormone (FSH, luteinizing hormone (LH, and CO were reduced. Computed tomography (CT of the adrenal glands and magnetic resonance imaging (MRI of the testes showed a soft tissue density (more pronounced on the right side and an irregularly swollen mass (more pronounced on the left side, respectively. Pathological examination of a specimen of the mass indicated polygonal/circular eosinophilic cytoplasm, cord-like arrangement of interstitial cells, and lipid pigment in the cytoplasm. Immunohistochemistry results precluded a diagnosis of Leydig cell tumors. DNA sequencing revealed a hackneyed homozygous mutation, I2g, on intron 2 of the CYP21A2 gene. The patient’s symptoms improved after a three-month of dexamethasone therapy. Recent radiographic data showed reduced hyperplastic adrenal nodules and testicular tumors. A diagnosis of TART should be considered and prioritized in CAH patients with testicular tumors. Replacement therapy using a sufficient amount of dexamethasone in this case helps combat TART.

    Full Text Available BackgroundOrbital metastases are an uncommon finding, being present in just 9% deceased patients with metastatic cancer. Only a quarter of patients with choroidal metastases have bilateral disease. Parotid cancer is not a common form of head and neck malignancy. Bilateral multifocal metastases from adenocarcinoma ex pleomorphic of parotid gland have been documented just once before in the literature. We present a similar case where palliative EBRT was used to gain local control with minimal toxicity.Case PresentationThe case of a 45 year old Caucasian gentleman who presented to his general practitioner with otalgia and weight loss. Imaging revealed a mass in the deep lobe of the left parotid gland, invading into the medial pterygoid muscle. PET-CT revealed locoregional and distant lymphatic involvement plus disseminated skeletal metastases. Lymph node examination revealed adenocarcinoma ex pleomorphic histology. Within weeks of this diagnosis, the patient developed rapidly progressive visual impairment. Ophthalmologists found multifocal uveal masses bilaterally. Palliative fractions of external beam radiotherapy were delivered to the orbits before combination chemotherapy. We discuss the patient's presentation, histopathology and management, with support from the literature regarding applied and related therapies. SummaryIn this rare presentation of disseminated malignancy affecting the choroid bilaterally, the authors demonstrate the application of palliative EBRT to good local effect. Given the nature of this treatment and that of the metastases, in the setting of incurable disease orbital morbidity is likely to occur again before the patient's death. Awareness of the initial symptoms is important to provide prompt care and maintain quality of life.

    Directory of Open Access Journals (Sweden)

    Sonir R. Antonini

    2004-10-01

    Full Text Available A AIMAH é caracterizada pela presença de macronódulos em ambas as adrenais, na ausência da estimulação do ACTH. Habitualmente, as manifestações clínicas aparecem somente após várias décadas de vida, provavelmente em função da baixa atividade esteroidogênica do tecido hiperplásico. Entretanto, em indivíduos assintomáticos cuja AIMAH foi descoberta acidentalmente, o eixo HHA já se encontra alterado. Estudos têm demonstrado que, na maioria dos casos de AIMAH, a secreção de cortisol é regulada de modo "aberrante" por hormônios como o GIP, AVP, catecolaminas, LH/hCG e serotonina, através de seus respectivos receptores, ectópicos ou eutópicos, porém aberrantemente acoplados à esteroidogênese. Os mecanismos moleculares responsáveis pela expressão ectópica dos receptores hormonais e/ou de seu acoplamento anormal à esteroidogênese adrenal ainda são pouco conhecidos. Embora a expressão aberrante destes receptores hormonais possa desempenhar um papel importante na iniciação da proliferação celular aumentada, bem como na esteroidogênese, é provável que eventos genéticos adicionais ocorram, envolvendo a regulação do ciclo celular, adesão e transcrição. Mutações no gene GNAS1 não associadas à síndrome de McCune-Albright podem ser encontradas em raros casos de AIMAH. Em alguns casos, a presença de receptor hormonal aberrante abre novas possibilidades de tratamento farmacológico específico do hipercortisolismo, seja isolado ou associado à adrenalectomia unilateral.AIMAH is a clinical condition characterized by the presence of adrenal macronodules even in the absence of ACTH. Usually the clinical overt syndrome only becomes apparent after several decades of life; this is probably due to the low steroidogenic enzyme capacity of the hyperplastic tissue. However, in asymptomatic individuals in whom the AIMAH was incidentally discovered, the HHA axis is usually disrupted. In the great majority of AIMAH cases

    Ovarian metastases represent about 3-5% of all ovarian malignancies. Most of these tumors originate in the digestive tract and cholangiocarcinoma rarely involves the ovary. A 60-year-old woman was admitted for the investigation of abdominal distension that had lasted 1 week. One and a half years prior, the patient had undergone choledochal cyst excision, Roux-en Y hepaticojejunostomy and cholecystectomy. Computed tomography scans of the abdomen revealed a papillary mass in the remnant distal common bile duct and enlargement of both ovaries with a huge amount of ascites. An explorative laparotomy disclosed no peritoneal seeding with resectable cholangiocarcinoma and bilateral ovarian mass. Pylorus-preserving pancreatoduodenectomy and bilateral salphingo-oophorectomy with hysterectomy were performed. Histologically, it was a well-differentiated adenocarcinoma and all surgical margins were free of tumor. Both ovarian masses were consistent with metastatic adenocarcinoma from the common bile duct. The patient received six cycles of postoperative adjuvant systemic chemotherapy, dying after 10 months due to pulmonary embolism. PMID:26155281

    2016-01-01

    The (18)F-FDG PET/CT scan has been suggested for whole-body imaging to identify ectopic adrenocorticotrophic hormone secreting tumours, but there are some challenges involved. The case of a patient is presented, who was admitted with the pre-diagnosis of ectopic ACTH syndrome. On the CT, a nodular lesion was detected in the medial segment of the right lung. The FDG uptake of the lesion seemed to be increased visually, but was not pathological quantitatively (SUVmax: 1.8) on the PET/CT. There was also diffuse increased uptake (SUVmax: 14.2) in the enlarged adrenal glands. The lesion was reported as a possible malignant lesion with low FDG affinity, such as a low grade neuroendocrine tumour, while the diffuse enlarged adrenal glands with high uptake were interpreted as diffusely hyperplasic, due to Cushing's syndrome. The patient was treated with a surgical wedge resection. The histopathological diagnosis confirmed that the tumour was a grade 1 well-differentiated neuroendocrine carcinoma. PMID:26522002

    Primary hyperaldosteronism due to aldosterone secreting adrenal adenomas is an important and potentially curable cause for hypertension. The differentiation between unilateral or bilateral adrenal adenomas is crucial, as unilateral adenomas can easily be cured by surgery whereas bilateral adenomas have to be treated conservatively. Exact diagnosis can be made when unilateral or bilateral hormone production is proven with adrenal vein sampling. We present an effective step-by-step technique how to perform an adrenal vein sampling with a special emphasis on how to reliably catheterize the right adrenal vein using Dyna CT

Results: A 31-year male, presented with fever and weight loss for 3½ months with anorexia, nausea, hyperpigmentation of skin, and buccal mucosa and weakness with past h/o adequately treated pulmonary tuberculosis at 3 years of age. On examination, the patient was anemic. A non-tender, firm right (Rt. submandibular lymphnode was palpable. Investigations revealed: High erythrocyte sedimentation rate (ESR, negative HIV, and sputum for acid fast bacilli (AFB. Initial cortisol was high but subsequently became low with negative short synacthin test (SST. Computed tomography showed bilateral (B/L enlarged hypodense adrenal mass with inconclusive fine needle aspiration cytology (FNAC and negative AFB culture. Rt. submandibular lymph node FNAC showed caseating granuloma. ATDs and steroids were started, the lymphadenopathy regressed and symptoms subsided. However, after 1 year of treatment steroid withdrawal failed and adrenal size remained the same. Conclusion: The adrenal has considerable capacity to regenerate during active infection and ultimately become normal or smaller in size. However, in the case reported here, they failed to regress. Reversal of adrenal function following ATD is a controversial issue. Some studies have shown normalization following therapy, while others have contradicted it similar to the finding in our case.

  1. Adrenal incidentalomas. Primary hyperaldosteronism

    International Nuclear Information System (INIS)

    Adrenal incidentalomas are masses incidentally discovered at X rays, ultrasound or MRI examination of the abdomen. In 100 CT scans, one can expect to find two incidentalomas on average. The article by Murat and Dupas is dealing with the strategy of biological, morphological and scintigraphic examinations to be performed in such patients, to assess whether the tumor is of a benign or a malignant nature. Zenatti et al propose a detailed exploration of the aldosterone pathways, since adrenal carcinoma may be responsible for a specific profile of the serum concentrations of mineralo-steroids, compatible with a blockade of the last step of the aldosterone synthesis. The exploration of primary hyperaldosteronism requires biological and imaging techniques. Tabarin et al summarize the main biological parameters and tests available for the diagnosis of this condition and delineate the indications of imaging techniques, associated to hormonal tests to distinguish between adenoma and bilateral adrenal hyperplasia.

    International Nuclear Information System (INIS)

    CT provides exquisite anatomic detail of normal and pathologic adrenal glands but little specificity as to the nature of adrenal masses. MR reliably distinguishes non-functioning and hyperfunctioning adenomas (adrenal mass/liver ratio 2.5). Metastases to the adrenal gland and primary adrenocortical carcinomas lie in the intermediate range (adrenal mass/liver ratio 1.4-2.5). Particularly problematic are masses with ratios in the 1.2-1.4 range since some non-functioning adenomas and some metastases will have similar signal intensities and cannot be distinguished.

  3. Usefulness of percentage enhancement washout value calculated on unenhanced, contrast-enhanced, and delayed enhanced CT in adrenal masses: adenoma versus metastasis

    International Nuclear Information System (INIS)

    To determine the usefulness of percentage enhancement washout value calculated on unenhanced, enhanced and delayed enhanced CT scans for the characterization of adrenal masses. Forty adrenal masses less than 5 cm in size were assessed using a protocol consisting of unenhanced CT, enhanced CT 60 seconds after intravenous administration of contrast material, and delayed enhanced CT at 10 minutes. The CT attenuation value of adrenal tumors was estimated on each scan, and percentage enhancement washout value was calculated as follows:[(attenuation value at enhanced CT-attenuation value at delayed CT)/ (attenuation value at enhanced CT-attenuation value at unenhanced CT)x100]. An adrenal mass was considered benign if its percentage enhancement washout value was at the threshold value, set to 60% and 50%, or higher. The accuracy of the procedure was determined by comparing its findings with the final clinical diagnosis. Twenty-nine massess were benign and 11 were malignant. The mean percentage enhancement washout value of the former was significantly higher than that of the latter (66.7% vs. 21.8%; p<0.01). All adenomas except one had a washout value of more than 50%. With a percentage washout threshold of 60%, 35 of 40 lesions were correctly characterized as benign or malignant [sensitivity 82.7% (24/29), specificity 100% (11/11), accuracy 87.5% (35/40)]; with a threshold of 50%, 39 of 40 lesions were correctly characterized [(sensitivity 96.5% (28/29), specificity 100% (11/11), accuracy 97.5% (39/40)]. Percentage enhancement washout values are useful for characterizing an adrenal mass as benign or malignant. For characterization, a threshold value of 50% was more accurate than one of 60%

    An 18-year-old man with a history of Cushing's disease was treated with a total right and a near total left adrenalectomy in 1956. Pathologic examination of the operative specimen revealed bilateral adrenal hyperplasia. After 13 years, recurrence of symptoms of cortisol excess necessitated cobalt irradiation to the pituitary, which was without clinical effect. After an initial response to the adrenolytic agent, o,p'-DDD, partial relapse occurred. At this time, the recognition of an abdominal mass prompted abdominal exploration revealing a huge adrenal myelolipoma containing adrenal cortical cells distributed diffusely throughout the tumor. Symptoms of adrenal insufficiency developed, and adrenal steroid secretion did not respond to exogenous adrenocorticotropic hormone postoperatively. The case illustrates that adrenal myelolipomas may become very large with continued stimulation by adrenocorticotropic hormone, may contain significant amounts of adrenal cortical tissue, and may be associated with clinical hypercortisolism.

    The exact localization of adrenal lesions can be achieved by noninvasive procedures. Whereas radiological methods reflect morphological changes, scintigraphy of adrenal cortex and medulla depends on function. - Radiolabeled 6β-methyl-19-norcholesterol is used for adrenocortical scintigraphy in primary aldosteronism, Cushing's syndrome and hyperandrogenism. By dexamethasone suppression a correct classification of adrenocortical lesions by scintigraphy can be observed in about 89% with a specificity of 86%. 123-I- and 131-I-metaiodobenzylguanidine is used for specific scintigraphy of the adrenal medulla. This method is a safe and reliable method for localization of adrenal and extraadrenal pheochromocytomas. (orig.)

  8. Magnetic resonance imaging of the adrenal gland

    International Nuclear Information System (INIS)

    Adrenal imaging was performed using magnetic resonance (MR) was in 100 patients who had no clinical or biochemical evidence of adrenal abnormality and in 19 patients with 24 adrenal lesions (adenoma in 5, hyperplasia in 2, metastasis in 5 (lung cancer in 1, hepatoma in 4), adrenal cancer in 1, pheochromocytoma in 3, neuroblastoma in 3). Normal adrenal glands showed intermediate intensity between muscle and liver, and were detected in over 90% of cases on T1-weighted images (T1-weighted SE, inversion recovery). Adenomas and hyperplasias had the same intensity as normal glands. Medullary masses showed extreme hyperintensity on T2-weighted images and could be differentiated from cortical masses. Neuroblastomas were detected as hyperintense tumors with intratumoral hemorrhage and necrosis on T2-weighted images. Metastatic adrenal tumors from lung cancer were hyperintense on T2-weighted images, while metastasis from hepatoma showed low intensity on the same pulse sequence. In diagnosing adrenal metastasis, we must compare and contrast the tumor intensity and structure with those of the primary lesions. MR is considered a useful modality in characterizing adrenal tissue. (author)

    CT or MRI are utilized in the initial evaluation of adrenal incidentalomas; however, overlap exists between benign and malignant lesions on these examinations. The American College of Radiology recommends PET scans to complement CT and MRI for patients with adrenal masses and a moderate-to-high likelihood of neoplastic disease. We present images of a PET-avid adrenal lesion in a patient with pulmonary and pancreatic neoplasms that mimicked metastasis, but was found to be a benign adrenal hemangioma on surgical resection. The use of PET for adrenal tumors, specifically adrenal hemangiomas, will be reviewed. PMID:24089061

    2000-10-01

    Full Text Available Incidentally discovered adrenal masses, or adrenal incidentalomas, have become a common clinical problem owing to wide application of radiologic imaging techniques. This definition encompasses a heterogeneous spectrum of pathologic entities, including primary adrenocortical and medullary tumors, benign or malignant lesions, hormonally active or inactive lesions, metastases, and infections. Once an adrenal mass is detected, the clinician needs to address two crucial questions: is the mass malignant, and is it hormonally active? This article provides an overview of the diagnostic clinical approach and management of the adrenal incidentaloma. Mass size is the most reliable variable to distinguish benign and malignant adrenal masses. Adrenalectomy should be recommended for masses greater than 4.0 cm because of the increased risk of malignancy. Adrenal scintigraphy has proved useful in discriminating between benign and malignant lesions. Finally, fine-needle aspiration biopsy is an important tool in the evaluation of oncological patients and it may be useful in establishing the presence of metastatic disease. The majority of adrenal incidentalomas are non-hypersecretory cortical adenomas but an endocrine evaluation can lead to the identification of a significant number of cases with subclinical Cushing's syndrome (5-15%, pheochromocytoma (1.5-13% and aldosteronoma (0-7%. The first step of hormonal screening should include an overnight low dose dexamethasone suppression test, the measure of urinary catecholamines or metanephrines, serum potassium and, in hypertensive patients, upright plasma aldosterone/plasma renin activity ratio. Dehydroepiandrosterone sulfate measurement may show evidence of adrenal androgen excess.

  15. Bilateral cystic neuroblastoma: imaging features and differential diagnoses

    International Nuclear Information System (INIS)

    Neuroblastoma is one of the most common malignant tumors of childhood, with 40 % arising in the adrenal glands. Bilateral adrenal involvement from synchronous development or metastatic spread of the tumor is seen in less than 10 % of children with neuroblastoma [1[. Neuroblastoma rarely presents as a cystic suprarenal mass that is difficult to differentiate from adrenal hemorrhage, extralobar sequestration, or dilated upper-pole renal calyces. To our knowledge, bilateral cystic neuroblastoma has not been previously reported. We present a case of bilateral cystic adrenal neuroblastoma to demonstrate the imaging features of this unusual entity, and to expand the differential diagnosis of bilateral cystic suprarenal masses in an infant.

    International Nuclear Information System (INIS)

    The visualization of functioning adrenocortical tissue by scintigraphy became possible with the introduction of radioiodinated cholesterol derivatives. According to the literature, there is evidence that one of these iodinated cholesterols, 6-β-iodomethyl-nor-cholesterol, concentrates in the adrenal cortex to a much greater extent than 131I-19-odocholesterol. Results comparing both radiopharmaceuticals are described. The authors investigated the possibility of increasing the uptake of iodinated cholesterol using simultaneous ACTH and the 'cholesterol side-chain cleavage enzymeblocker': aminoglutethimide. The results of adrenal scintigraphy performed in 37 patients are described. Finally, the literature on adrenal scintigraphy is reviewed, and results reported in various studies are compared. (Auth.)

  17. Limited significance of asymmetric adrenal visualization on dexamethasone-suppression scintigraphy

    International Nuclear Information System (INIS)

    To access whether a single measurement of the adrenal uptake of 6β-[131I]-iodomethylnorocholesterol (NP-59) on constant dexamethasone suppression would allow discrimination of adenoma from normal and bilateral hyperplasia, the adrenal uptake of 6β-[131I]-iodomethylnorocholesterol (NP-59) was determined in 50 patients with primary aldosteronism (30 adenoma, 20 hyperplasia) and in 13 with hyperandrogenism (six adenoma, seven hyperplasia). Bilateral adrenal NP-59 activity at 5 days was seen in 14 of 36 patients with adenoma whereas marked asymmetric uptake of NP-59 was seen in six of 27 patients with hyperplasia. Thus the level of adrenal NP-59 uptake does not alone serve to distinguish either adenoma from the normal, contralateral adrenal or the adrenal glands in bilateral hyperplasia in all cases. It appears that the pattern of adrenal imaging best serves to separate adrenal adenoma from bilateral hyperplasia

  19. Morphologic and functional evaluation of adrenal masses in patients with normal adrenal function using MR imaging and Np-59 scintigraphy

    International Nuclear Information System (INIS)

    MR imaging has shown promise in distinguishing metastasis from adenomas. Adrenal scintigraphy has also shown high specificity for adenoma detection. To determine if combined morphologic and functional data are superior to either data set alone, the authors evaluated 20 adenomas and 15 metastases using spin-echo MR imaging at 0.35T and Np-59 scintigraphy. Qualitative visual and quantitative analysis of MR data was done by means of intensity measurements and ratios of lesion to liver, kidney, fat, and muscle. Scintigraphic scan data were assigned to concordant, discordant, and indeterminate categories on the basis of visual assessment. The authors' preliminary data suggest that combined morphologic and functional data should result in more optimal tissue characterization, particularly in bilateral lesions

    Objective To study the clinical diagnosis and treatment of bilateral breast cancer with bone and cervical metastasis. Methods We retrospectively analyzed the clinical data of a case of bilateral breast cancer with bone and cervical metastasis in our hospital. Results The patient was a 52-year-old female,admitted for the right breast mass, which had been found more than one month before. Breast ultrasound showed substantial occupying lesions of bilateral breasts. The pathologic results of bilateral breast mass indicated all invasive lobular carcinoma. ECT of the whole body bone scanning showed systemic multiple bone metastases. B ultrasound in gynecology showed cervical hypoechoic occupying lesion. After the neoadjuvant chemotherapy, we performed operations of bilateral breast modified radical mastectomy and cervical neoplasm electrotomy. The postoperative pathological results showed that the bilateral breast tumors were invasive lobular carcinoma associated with axilla-ry lymph node metastasis. The pathological staging was IV( T1b ,N3 ,M1 ) . The result of immunohistochemistry showed that CK, S100, Mummaglobin and GCDFP-15 were positive, Ki67 was about 3% positive,ER was about 40% positive,PR was about 20% positive,while CerbB2 was negative. Then, the patient accepted the postoperative systemic treatment,such as chemother-apy, and endocrine therapy. The patient was checked every three months with a stable condition, and continued endocrine therapy. Conclusion The bone metastasis from breast cancer is a common condition,while the occurrence of metastasis to the neck of uterus is rare. The histopathological analysis combined with immunohistochemical detection is of great value in diagno-sis and treatment.%目的:探讨双侧乳腺癌伴骨及宫颈转移的临床诊治要点。方法对我院收治的双侧乳腺癌伴骨及宫颈转移1例的临床资料进行回顾性分析。结果本例52岁,因发现右乳腺包块1月余入院。乳腺彩色多普勒超声

    Adrenal injuries, although an uncommon consequence of abdominal trauma, are important to recognize. If bilateral, adrenal trauma could result in life-threatening adrenal insufficiency. Furthermore, in the setting of trauma, adrenal injury can point to other concomitant injuries and has been associated with overall increased morbidity and mortality. In the past, before the advent of computed tomography (CT), detection was difficult, and the diagnosis was often made only at surgery or postmortem. Today, the diagnosis of adrenal injuries can be quickly and accurately made with CT. This retrospective review was carried out to identify, describe, and analyze different CT appearances of adrenal injuries and correlated with associated injuries and observed clinical context and outcomes. A patient cohort of CT-detected adrenal injuries was identified through a radiology software research tool by searching for keywords in radiology reports. The identified CT scans were reviewed and correlated with the patients' available clinical chart data and follow-up. Between April 1995 and October 2004, 73 cases of CT-detected adrenal injuries were identified, including 48 men and 25 women, with an age range 6 to 90 years and a mean age of 42.7 years. Of the cases, 77% were right-sided, 15% were left-sided, and 8% were bilateral. The causes of injuries were motor vehicle collisions (75%), falls (14%), sports related (4%), and miscellaneous causes (7%). Associated trauma included injuries of the liver (43%), spleen (23%), lung (19%), and kidney (18%), as well as pneumothoraces/hemothoraces (22%). Skeletal injuries included fractures of the ribs, clavicles, and/or scapulae (39%), pelvis and hips (30%), and the spine (23%). Isolated adrenal trauma was seen in only 4% of the cases. The CT findings of adrenal trauma were focal hematoma (30%), indistinct (27%) or enlarged (18%) adrenal gland, gross (15%) or focal (7%) adrenal hemorrhage, and adrenal mass (11%). Associated CT findings

    Only a few cases of pedunculated hepatocellular carcinoma (P-HCC) have been reported in the literature. The common sites of extrahepatic metastases in patients with HCC are the lungs, regional lymph nodes,kidney, bone marrow and adrenals. Metastasis to spleen is mostly via hematogenous metastasis, direct metastasis to spleen was very rare. We report a case of P-HCC presenting as a left upper abdominal lesions which involved the spleen that was actually a P-HCC with splenic metastasis. This case is unique as P-HCC directly involved the spleen which is not via hematogenous metastasis.

  7. Diagnosis of adrenal tumors with radionuclide imaging

    International Nuclear Information System (INIS)

    The development of radiolabeled cholesterols in 1969 as precursors of adrenocortical steroid production allowed the first noninvasive imaging of the adrenal cortices. FDA-NDA approval in 1984 should allow routine use of these agents in most hospitals. NP-59 is most commonly used in the diagnosis and management of Cushing syndrome; the second most common use is in the diagnosis of primary aldosteronism. It is also helpful in the differential diagnosis of adrenal and ovarian hyperandrogenism and hirsutism, and is the only noninvasive method of detecting unilateral adrenocortical hypofunction. The newest and most popular use is in the differential diagnosis of asymptomatic masses in the region of the adrenal gland discovered incidentally with CT scan (incidentalomas). In this situation, the NP-59 scan can define whether the tumor is in the adrenal gland and if it is functional or nonfunctional. The authors believe that, in the future, radiolabeled enzyme inhibitors might offer better diagnostic imaging of the adrenal cortex, although these agents will probably not be available for routine use for some time. The development of a radioiodinated guanethidine analog, 131I-MIBG, has allowed differentiation of normal adrenal medullary function from bilateral adrenal medullary hyperplasia before the development of hypertension or tachycardia, diagnostic increases in plasma or urinary catecholamines, or abnormal CT scans. The search for a pheochromocytoma should begin with 131I-MIBG scintigraphy. While over 90% of primary pheochromocytomas occur in the abdomen, neither a survey of the abdomen nor the finding of a single tumor should conclude the search

    Full Text Available In this article, we have discussed about two cases of adrenal myelolipoma and aim to discuss the role of imaging in their diagnosis and their management. Different imaging techniques such as ultrasound, computed tomography and magnetic resonance imaging were used to aid in diagnosis in each of the cases. The findings have been highlighted here. In each of the cases, the diagnosis could be confirmed by imaging, and there was cholelithiasis seen associated with unilateral adrenal myelolipoma. Adrenal myelolipomas are rare, benign, non-functional tumors of adrenal gland. Most tumors are unilateral and small; bilateral, giant myelolipomas are extremely rare. The association of adrenal myelolipoma with gallstones is uncommon. To our knowledge only two cases of such an association have been reported in the literature. However, the possibility does exist and steps should be taken to ensure a complete diagnosis. Also, it is important to understand the key points which help us in diagnosing adrenal myelolipomas by imaging.

    Metastatic spread of differentiated thyroid cancer to genitourinary organs is rare. Synchronous presentation of renal and adrenal thyroid metastasis is even less common, this case being only the 3rd reported. We describe a case of a 60-year-old male with oligometastatic thyroid cancer, where adrenal and renal metastases were the only extracervical sites of disease and triggered the patient's presentation.

  18. Computed tomography in primary and secondary adrenal tumours

    International Nuclear Information System (INIS)

    The purpose of the study was to find out how reliably benign and malignant adrenal tumours can be differentiated on the basis of CT characteristics. The material included 86 adrenal tumours with the following confirmed diagnoses: 48 primary adrenal tumours (8 carcinomas, 1 neuroblastoma, 4 pheochromocytomas, 31 adenomas, 3 cysts, 1 haemangioma) and 38 metastases. The size, density, homogeneity, enhancement and growth of the tumours were evaluated. No specific CT findings could separate benign from malignant tumours. Coexistence of cancer and bilateral non-homogenous adrenal masses is probably sufficient for the diagnosis of adrenal metastases. In cases of coincidental small (< 3 cm), homogeneous and relatively hypodense masses with no signs of hormonal activity, a follow-up examination of the lesion within three months is recommended. Other masses may indicate further diagnostic procedures. (orig.)

  19. Dexamethasone-suppression adrenal scintigraphy in hyperandrogenism: concise communication

    International Nuclear Information System (INIS)

    To assess the contribution of adrenal-derived androgens in women with hirsutism, adrenal scintigrams under dexamethasone suppression (DS) were performed on 35 women with increasing facial or body hair and irregular or absent menses. Based upon the DS regimen chosen (8 mg/d for 2 days or 4 md/d for 7 days before the injection of 6β-[131I]iodomethylnorcholesterol), three imaging patterns were identified. The first was the absence of uptake before 3 days (8-mg DS) or before 5 days (4-mg DS) after injection. This imaging pattern was seen in 17 of the 35 patients studied and was considered normal. The second pattern was bilateral uptake earlier than 3 days (8-mg DS regimen) or 5 days (4-mg DS) after injection. This was seen in 13 of the 35 patients and was interpreted as bilateral early visualization. Adrenal-vein catheterization performed on six patients with this pattern showed increased adrenal-vein testosterone. The third pattern, observed in five patients, was unilateral early visualization, which in four cases investigated to date was the result of an adrenocortical adenoma. This study confirms the adrenal cortex as a source of androgens in women with hirsutism and hyperandrogenism and demonstrates that DS adrenal scintigraphy can be utilized to identify those women in whom adrenal-derived androgens contribute to their hyperandrogenism

    1984-01-01

    The development of radiolabeled cholesterols in 1969 as precursors of adrenocortical steroid production allowed the first noninvasive imaging of the adrenal cortices. FDA-NDA approval in 1984 should allow routine use of these agents in most hospitals. NP-59 is most commonly used in the diagnosis and management of Cushing syndrome; the second most common use is in the diagnosis of primary aldosteronism. It is also helpful in the differential diagnosis of adrenal and ovarian hyperandrogenism and hirsutism, and is the only noninvasive method of detecting unilateral adrenocortical hypofunction. The newest and most popular use is in the differential diagnosis of asymptomatic masses in the region of the adrenal gland discovered incidentally with CT scan (incidentalomas). In this situation, the NP-59 scan can define whether the tumor is in the adrenal gland and if it is functional or nonfunctional. The authors believe that, in the future, radiolabeled enzyme inhibitors might offer better diagnostic imaging of the adrenal cortex, although these agents will probably not be available for routine use for some time. The development of a radioiodinated guanethidine analog, /sup 131/I-MIBG, has allowed differentiation of normal adrenal medullary function from bilateral adrenal medullary hyperplasia before the development of hypertension or tachycardia, diagnostic increases in plasma or urinary catecholamines, or abnormal CT scans. The search for a pheochromocytoma should begin with /sup 131/I-MIBG scintigraphy. While over 90% of primary pheochromocytomas occur in the abdomen, neither a survey of the abdomen nor the finding of a single tumor should conclude the search.

  2. MR imaging features of adrenal rest tumor

    International Nuclear Information System (INIS)

    Objective: To investigate the imaging features of adrenal rest tumor. Methods: Twelve patients of adrenal rest tumor proved by surgery or clinical diagnosis were retrospectively analyzed. Among these 12 patients, 12 were examined with ultrasound, 11 with MR and 1 with CT. MR and CT were performed without and with intravenous injection of contrast material. The imaging features of adrenal rest tumor were retrospectively summarized and the relevant literatures reviewed. Results: The adrenal rest tumors were found in testis in 10 of the 12 patients, and in ovaries and broad ligament in the remaining two. The imaging features of the testicular adrenal rest tumor were summarized as following: all patients had bilateral testicular masses without change of the testicular contour. On ultrasonography, the lesions were hypoechoic, with some hyperechoic areas and appeared highly vascularized on Colour Doppler ultrasonography. The masses showed iso-density on plain CT, and avid enhancement on post-contrast CT images. The masses ranging in size from 0.7 cm×1.0 cm×2.2 cm to 2.3 cm ×2.7 cm ×2.9 cm with uniform signal intensity, lobulated margin on MRI. They exhibited iso- or slight hyperintensity on T1WI and hypointensity on T2WI relative to normal testicular parenchyma. The tumors showed intense enhancement on post-contrast MR images. No abnormality was detected with Colour Doppler ultrasonography and MR in 2 patients of adrenal rest tumor in ovaries and broad ligament. Conclusion: Combining imaging features with the typical clinical history,the diagnosis of adrenal rest tumor could be suggested pre-operatively. (authors)

    Primary aldosteronism (PA) is a common cause of secondary hypertension and is caused by unilateral or bilateral adrenal disease. Treatment options depend on whether the disease is lateralized or not, which is preferably evaluated with selective adrenal venous sampling (AVS). This procedure is technically challenging, and obtaining representative samples from the adrenal veins can prove difficult. Unsuccessful AVS procedures often require reexamination.

  4. Computed tomography findings in diseases of the adrenal gland

    International Nuclear Information System (INIS)

    The adrenal gland is a common site of disease, with an abnormality prevalence as high as 9% in autopsy series. With the increasing use of CT, adrenal lesions are frequently found in the daily practice of radiology and are diagnosed in up to 5% of CT examinations performed for varied reasons. Imaging features on CT can establish a specific diagnosis of many of these lesions, including myelolipoma, hematoma and cysts. Once a diagnostic dilemma, now adenomas can be accurately diagnosed using unenhanced CT, chemical shift magnetic resonance imaging and CT contrast washout analysis. Because the adrenal gland is also a frequent site of metastasis, recent literature has focused on imaging characterization of adrenal masses for differentiation of adenomas from metastases. In patients without known malignancy, most adrenal lesions are benign and a specific diagnosis can now be made on the basis of imaging features. It is important to understand the prevalence of adrenal abnormalities because the gland is a common site of disorders, and the increased use of cross-sectional imaging has increased the frequency of detection of adrenal lesions. The prevalence of disease is important in predicting the risk of malignancy when an adrenal mass is discovered in a patient without known cancer. Detection of adrenal gland diseases has increased substantially with the advent and widespread use of imaging techniques. Although several imaging modalities can be used, CT has a central role in both detection and differential diagnosis of an adrenal lesion. The aim of this article is to review the CT findings of adrenal gland diseases. (author)

  5. Aberrant expression of glucagon receptors in adrenal glands of a patient with Cushing's syndrome and ACTH-independent macronodular adrenal hyperplasia

    2010-06-01

    Full Text Available Adrenocorticotropin (ACTH independent bilateral macronodular adrenal hyperplasia (AIMAH is a rare cause of Cushing´s syndrome, characterized by bilateral adrenal lesions and excess cortisol production despite ACTH suppression. Cortisol synthesis is produced in response to abnormal activation of G-protein- coupled receptors, such as gastric inhibitory peptide, vasopressin, beta adrenergic agonists, LH/hCG and serotonin receptors. The aim of this study was to analyze the expression of glucagon receptors in adrenal glands from an AIMAH patient. A patient with ACTH-independent Cushing´s syndrome and bilateral macronodular adrenal hyperplasia was screened for altered activation of adrenal receptors by physiological (mixed meal and pharmacological (gonadotrophin releasing hormone, ACTH and glucagon tests. The results showed abnormally high levels of serum cortisol after stimulation with glucagon. Hypercortisolism was successfully managed with ketoconazole treatment. Interestingly, a 4-month treatment with a somatostatin analogue (octreotide was also able to reduce cortisol secretion. Finally, Cushing's syndrome was cured after bilateral adrenalectomy. Abnormal mRNA expression for glucagon receptor in the patient´s adrenal glands was observed by Real-Time PCR procedure. These results strongly suggest that the mechanism of AIMAH causing Cushing´s syndrome in this case involves the illicit activation of adrenal glucagon receptors. This is the first case reported of AIMAH associated with ectopic glucagon receptors.

    Adrenal myelolipoma is a rare benign tumor composed of adipose and hematopoietic tissue. Most tumors are small in size and incidentally detected. We report a case of giant adrenal myelolipoma weighing 2200 gms which was diagnosed on radiology as a liposarcoma. This case is unusual in view of the large size and presence of bony spicules. To the best of our knowledge, not more than 10 giant adrenal myelolipoma cases have been reported in literature.

    We wanted to evaluate the MDCT findings and concomitant injuries of traumatic adrenal injury in children. Among 375 children who had undergone a MDCT scan for abdominal trauma during the recent five years at our institution, 27 children who had revealed adrenal injury on their CT scan were included in the study. We retrospectively evaluated the causes of the trauma, the patterns of adrenal injury, the associated CT findings and the concomitant injuries of the other organs in the abdomen. We identified 27 children (7.5%) (17 boys and 10 girls, mean age: 9.9 years, range: 2-18 years) with adrenal injury. The causes of adrenal injury were a traffic accident for 20 patients (74%), falls for four patients (15%) and blunt trauma for three patients (11%). The right adrenal gland was injured in 20 patients (74%), while the left adrenal gland was injured in three patients and bilateral involvement was noted in four patients. The patterns of adrenal injury were round or oval shaped hematoma in 23 lesions (74%), irregular hemorrhage with obliterating the gland in six lesions (19%) and active extravasation of contrast material from the adrenal region in two lesions (7%). Concomitant injuries were noted in 22 patients (81%), including 15 patients with liver laceration (56%), 11 patients with lung contusion (41%) and nine patients with renal injury (33%). The frequency of adrenal injury was 7.5%. The right adrenal gland was more frequently involved. Concomitant organ injury was noted 81% of the patients and the most frequently involved organ was the liver (56%)

  10. Role of multidetector row computed tomography in the assessment of adrenal gland injuries

    International Nuclear Information System (INIS)

    Objective: To determine the prevalence of adrenal injuries in a group of patients submitted to multidetector row CT evaluation after blunt trauma and to assess the impact of CT findings on clinical management decisions. Materials and method: During a 4-year period, 2026 emergency CT examinations were performed in the setting of major blunt trauma. A total of 82 patients were retrospectively identified as having adrenal gland traumatic lesions. At multidetector row CT the following findings were considered specific of adrenal injury: round or oval hematoma expanding the adrenal gland, irregular hemorrhage obliterating the gland, uniform adrenal gland swelling, active extravasation of contrast material from the adrenal vessels and adrenal gland rupture. Associated CT findings were: stranding of the periadrenal fat, diffuse hemorrhage in the adjacent retroperitoneum and compression of the adrenal gland by adjacent traumatic lesions. Results: We identified 82 patients (46 males and 36 females, age ranging from 15 to 86 years) with adrenal injuries. The right adrenal gland was injured in 60/82 patients, while the left adrenal gland was injured in 21 cases; in 1 patient bilateral adrenal gland traumatic lesions occurred. In 76 patients with non-isolated adrenal injuries concomitant injuries to the liver (49 cases), ipsilateral kidney (18 cases) and spleen (9 cases) were observed. Round or oval hematoma expanding the adrenal gland (61 cases), irregular hemorrhage obliterating the gland (14 cases), stranding of the periadrenal fat (9 cases) and diffuse hemorrhage in the adjacent retroperitoneum (8 cases) were the more frequent findings detected at CT. Six patients underwent surgical intervention for the presence of major injuries to the spleen (three cases), to the liver (one), to the right kidney (one), to the left kidney (one). Seventy-six patients were conservatively treated. Conclusion: Blunt adrenal injuries typically present as part of a multiorgan trauma

    A 31-year-old woman was referred to our hospital with symptoms of hypertension and bilateral adrenocortical masses with no feature of Cushing syndrome. The serum aldosterone/renin ratio was elevated and the saline loading test showed no suppression of the plasma aldosterone level, consistent with a diagnosis of primary hyperaldosteronism. Overnight and low-dose dexamethasone suppression tests showed no suppression of serum cortisol, indicating a secondary diagnosis of subclinical Cushing syndrome. Adrenal vein sampling during the low-dose dexamethasone suppression test demonstrated excess secretion of cortisol from the left adrenal mass. A partial right adrenalectomy was performed, resulting in normalization of blood pressure, hypokalemia, and high aldosterone level, implying that the right adrenal mass was the main cause of the hyperaldosteronism. A total adrenalectomy for the left adrenal mass was later performed, resulting in a normalization of cortisol level. The final diagnosis was bilateral adrenocortical adenomas, which were secreting aldosterone and cortisol independently. This case is the first report of a concurrent cortisol-producing left adrenal adenoma and an aldosterone-producing right adrenal adenoma in Korea, as demonstrated by adrenal vein sampling and sequential removal of adrenal masses.

    Adrenal tumors are increasingly detected by widespread use of anatomical imaging such as CT, MRI, etc. For these adrenal tumors, differentiation between malignancy and benignancy is very important. In diagnostic assessment of adrenal tumor, {sup 18}F-FDG PET and PET-CT have been reported to have high diagnostic performance, especially, very excellent performance in evaluation of adrenal metastasis in the oncologic patient. In cases of adrenal incidentalomas, {sup 18}F-FDG PET or PET-CT is helpful if CT or chemical-shift MRI is inconclusive. {sup 18}F-FDG PET and PET-CT may be applied to the patients with MIBG-negative pheochromocytomas. In summary, {sup 18}F-FDG PET and PET-CT are expected to be effective diagnostic tools in the management of adrenal tumor.

  13. Validity of computerized tomography in adrenal diseases

    International Nuclear Information System (INIS)

    For diagnosis of adenomas in primary aldosteronism CT proved to be helpful. Although microadenomas have to be ruled out by selective venous sampling from both adrenal glands adenomas down to 8 mm in diameter can be visualized. Scintigraphy does not always permit reliable differentiation of unilateral adenoma from bilateral hyperplasia. - In endogenous Cushing's syndrome adrenal carcinomas are underlying etiologically in about 10% of the cases. Since carcinomas are detected easily by CT it should be performed in the first place. Whereas adenomas and hyperplasia are easily diagnosed by scintigraphy carcinomas may escape scintigraphy. - Pheochromocytomas, if situated in the vicinity of the kidneys, can be localiced safely by CT. Contrary to adenomas, carcinomas and pheochromocytomas may be detected by CT without difficulty because of their size. (orig.)

    Full Text Available Adrenal sarcomatoid carcinomas are extremely rare tumors presenting with extensive locoregional spread at the time of diagnosis. Patients succumb to metastases within a couple of months. As a result, very few cases are reported in the literature until now. We present a case of a 62-year old female with non-functional sarcomatoid carcinoma of the right adrenal gland. There was no radiological evidence of locoregional metastases. Patient underwent right adrenalectomy. Follow up after 3 months showed para-aortic lymphadenopathy and similar left adrenal mass on computed tomography. Patient refused further treatment and succumbed to the disease. A brief case report with review of literature is presented.

  15. Horseshoe adrenal gland in association with asplenia: presentation of six new cases and review of the literature

    Asplenia syndrome is a form of heterotaxy characterized by bilateral right-sidedness. Congenital fusion of the adrenal glands (''horseshoe adrenal gland'') is a less common feature of asplenia syndrome, most instances of which have been found at autopsy.Purpose. To present clinical and imaging features of infants diagnosed with asplenia syndrome and horseshoe adrenal gland.Materials and methods. Six infants with asplenia syndrome were identified as having a horseshoe adrenal gland. Medical records and imaging studies were reviewed to determine clinical presentation, associated anomalies, and outcome. The literature was reviewed for prior reports of horseshoe adrenal gland.Results. Horseshoe adrenal gland was identified in five infants by sonography and one by CT, the latter confirmed by autopsy. In all cases, the horseshoe adrenal gland was pre-aortic. Besides features of asplenia syndrome, one infant also had associated vertebral anomalies and bilateral renal agenesis. Including the current cases, of 65 reported cases of horseshoe adrenal gland 34 (52%) were associated with asplenia, 24 (37%) with neural tube defects, 19 (29%) with renal anomalies, and 2 (3%) with Cornelia de Lange syndrome. Horseshoe adrenal gland has not been reported with polysplenia syndrome.Conclusions. Horseshoe adrenal gland is a less common manifestation of asplenia that may be demonstrated by imaging. Horseshoe adrenal gland may be a differentiating feature between asplenia and polysplenia. (orig.)

    Full Text Available Acute dacryoadenitis is an uncommon condition that involves inflammation of the lacrimal gland. In rare instances, dacryoadenitis may be bilateral. A delay in proper treatment of an otherwise simple case of dacryoadenitis may lead to significant soft tissue morbidity such as cellulitis, lacrimal gland abscess, or orbital abscess. We report the case of a 24-year-old male who presented to the emergency department with acute bilateral dacryoadenitis. The patient′s symptoms did not respond to oral antibiotics and he subsequently required admission for intravenous antibiotics. During his hospitalization the patient had diagnostic testing to try to determine the etiology for his symptoms. The unique aspects of managing a case of bilateral dacryoadenitis as well as treatment recommendations are discussed in this case report.

  1. An unusual case of metastasis to the left side of the heart: a case report

    2011-01-01

    Full Text Available Abstract Introduction Cardiac metastases are found in six to 20% of autopsies of patients with malignant neoplasm. The most common neoplasms that metastasize to the heart are malignant melanoma, lymphoma, and leukemia, but the relative numbers are greater with breast and lung cancers, reflecting the most common incidence of these cancers. Case presentation A 60-year-old Hispanic man presented to our hospital after being transferred from an outside hospital for workup and evaluation of an adrenal mass of the abdomen and pelvis, found on computed tomography. His chief complaint upon admission was altered mental status. Physical examination was unremarkable. He was alert and oriented and had a dry and non-erythematous oropharynx, and bilateral diffuse wheezing on lung examination. Computed tomography of the chest showed multiple hypodense lesions in the left ventricular myocardium, suggestive of metastases. There were also tiny sub-centimeter nodular densities in the right upper and lower lobes. Adrenal glands contained hypodense lesions, which showed characteristic adenocarcinomatous malignant cells. Conclusion Cancers which have metastasized to the heart are found in six to 20% of patients with malignant neoplasms. The right side of the heart is more commonly involved in metastasis. This study is unusual in that a tumor of an unknown primary origin had metastasized to the left side of the heart.

  2. Evaluation of incidentally discovered adrenal masses with PET and PET/CT

    International Nuclear Information System (INIS)

    Background and purpose: Incidentally discovered adrenal masses are commonly seen with high resolution diagnostic imaging performed for indications other than adrenal disease. Although the majority of these masses are benign and non-secretory, their unexpected discovery prompts further biochemical and often repeated imaging evaluations, sufficient to identify hormonally active adrenal masses and/or primary or metastatic neoplasms to the adrenal(s). In the present paper we investigate the role of PET and PET/CT for the detection of adrenal incidentalomas in comparison with CT and MRI. Materials and methods: a systematic revision of the papers published in PubMed/Medline until September 2010 was done. Results: The diagnostic imaging approach to incidentally discovered adrenal masses includes computed tomography (CT), magnetic resonance imaging (MRI) and more recently positron emission tomography (PET) with radiopharmaceuticals designed to exploit mechanisms of cellular metabolism, adrenal substrate precursor uptake, or receptor binding. Conclusion: The functional maps created by PET imaging agents and the anatomic information provided by near-simultaneously acquired, co-registered CT facilitates localization and diagnosis of adrenal dysfunction, distinguishes unilateral from bilateral disease, and aids in characterizing malignant primary and metastatic adrenal disease.

    Full Text Available Metastatic spread of differentiated thyroid cancer to genitourinary organs is rare. Synchronous presentation of renal and adrenal thyroid metastasis is even less common, this case being only the 3rd reported. We describe a case of a 60-year-old male with oligometastatic thyroid cancer, where adrenal and renal metastases were the only extracervical sites of disease and triggered the patient's presentation.

  4. Contemporary adrenal scintigraphy

    International Nuclear Information System (INIS)

    High-resolution computed tomography (CT) and magnetic resonance (MR) imaging have replaced scintigraphy as primary imaging modalities for the evaluation of adrenal diseases. Thin-slice CT, CT contrast washout studies and MR pulse sequences specifically designed to identify adrenal lipid content have radically changed the approach to anatomic imaging and provide unique insight into the physical characteristics of the adrenals. With a confirmed biochemical diagnosis, further evaluation is often unnecessary, especially in diagnostic localization of diseases of the adrenal cortex. However, despite the exquisite detail afforded by anatomy-based imaging, there are not infrequently clinical situations in which the functional insight provided by scintigraphy is crucial to identify adrenal dysfunction and to assist in localization of adrenocortical and adrenomedullary disease. The introduction of hybrid PET/CT and SPECT/CT, modalities that directly integrate anatomic and functional information, redefine the radiotracer principle in the larger context of high-resolution anatomic imaging. Instead of becoming obsolete, scintigraphy is an element of a device that combines it with CT or MR to allow a direct correlation between function and anatomy, whereby the combination creates a more powerful diagnostic tool than the separate component modalities.

  5. Retroperitoneal extra-adrenal paraganglioma: a rare but important diagnosis.

    LENUS (Irish Health Repository)

    Ahmad, S

    2012-01-31

    BACKGROUND: Extra-adrenal paragangliomas of the retroperitonium are infrequently diagnosed. Their malignant behaviour cannot be predicted on initial clinical and histological assessment. These tumours have higher propensity for subsequent metastasis compared with pargangliomas at other sites. AIM: We aim to describe a case report of an incidental finding of left retroperitoneal paraganglioma in a young man who presented with right flank pain. We also aim to emphasize the importance of diagnosis and the malignant potential of these tumours. METHOD: Patient\\'s clinical notes, operative findings, imaging studies and laboratory investigations including histology results were reviewed. A literature search was done to look into the incidence, presentation, follow-up plan and treatment options for these tumours. CONCLUSION: Surgical resection is the only available curative option for extra-adrenal paragangliomas. Metastasis is observed years after surgery, hence long-term follow-up is required.

  6. Radiologic evaluation of adrenal glands

    International Nuclear Information System (INIS)

    When a diagnosis of adrenal disorder is suspected on the basis of clinical manifestations and/or laboratory findings, computed tomography (CT) is generally accepted as the imaging procedure of choice for visualization of adrenal areas and localization of lesions. Sonography keeps an important role in discovering adrenal masses during investigation for other suspected abnormality (incidentaloma). 131 I MIBG scintigraphy provides an efficious mean of pheochromocytoma localization and functional characterization. These non invasive procedures have greatly reduced the need for arteriography and venography; adrenal venous sampling is still an useful method for localizing either a tumor or hyperplasia related to primary aldosteronism. MR imaging and CT are nearly equivalent in the detection of adrenal masses: besides MR imaging has a potential for characterization of adrenal masses which might be useful, especially in distinguishing adrenal adenomas from malignant neoplasms, obviating, in some cases, the need of CT guided adrenal biopsy

  7. Voluminous adrenal masses

    International Nuclear Information System (INIS)

    Management of voluminous adrenal gland tumor (> 5 cm) is a clinical challenge. Only 33 % of these lesions are malignant. Surgical treatment is not always necessary. Several investigations as biochemical assessment, nuclear medicine, studies, arteriography, computed tomography or magnetic resonance imaging are useful in order to approach the diagnosis. Unfortunately, none has sufficient diagnostic specificity to distinguish malignant from benign lesions. After a review of clinical, biochemical, radiological characteristics of the main adrenal gland tumors, we have defined the advantages and the defaults of different imaging modalities. A simple management plan of voluminous adrenal gland lesion is proposed. The study is based upon the analysis of 63 cases reported by several authors. (authors). 16 refs., 6 figs

    2010-01-01

    Full Text Available Nonclassic congenital adrenal hyperplasia (NCAH due to P450c21 (21-hydroxylase deficiency is a common autosomal recessive disorder. This disorder is due to mutations in the CYP21A2 gene which is located at chromosome 6p21. The clinical features predominantly reflect androgen excess rather than adrenal insufficiency leading to an ascertainment bias favoring diagnosis in females. Treatment goals include normal linear growth velocity and “on-time” puberty in affected children. For adolescent and adult women, treatment goals include regularization of menses, prevention of progression of hirsutism, and fertility. This paper will review key aspects regarding pathophysiology, diagnosis, and treatment of NCAH.

  9. Imaging of adrenal disorders

    International Nuclear Information System (INIS)

    Adrenal scintillation scanning, CT and ultrasonography are compared with the conventional imaging methods. The accuracy of retroperitoneal pneumography and adrenal venography are not high, and they detected only large tumors such as Cushing's syndrome and pheochromocytoma. Scintillation scanning is highly effective for the diagnoses of primary aldosteronism and Cushing's syndrome. However, this technique does not visualize pheochromocytoma or hypopituitarism. CT is noninvasive and of high diagnostic value. It is impossible to diagnose tumors by ultrasonography unless the size is more than 3 cm. (Chiba, N.)

  10. MRI of adrenal masses

    International Nuclear Information System (INIS)

    The diagnostic usefulness of MRI was evaluated on 38 adrenal masses. The most important finding differentiating adenomas from metastases was the size of the tumor and the signal intensity of the mass. Adenomas showed a tendency to be smaller and homogeneous in signal intensity. On MRI with Gd-DTPA adenomas also showed moderate homogeneous enhancement, but metastases were inhomogeneously enhanced. The detectability by MRI was almost comparable with CT. Three cases of small adenomas and hyperplasia 1-1.5 cm in diameter were detectable only with CT. MRI seems to be complementary to CT in the diagnosis of adrenal masses. (author)

  11. Adrenal scintigraphy using 131I-Adosterol

    International Nuclear Information System (INIS)

    131I-Adosterol (6β-iodomethyl-19-norcholest-5(10)-3β-ol) was administered to evaluate adrenal grand in 20 patients including 9 patients with primary aldosteronism, 5 with Cushing's syndrome, one with pheochromocytoma, one with retroperitoneal tumor, 3 with essential hypertension and one with obesity. Standard scintigraphies were performed at 3rd day and again 6th day after administration of 131I-adosterol (1-1.5 mCi). Suppression scintigraphies were obtained while the patients were taking dexamethasone 2 to 3 mg daily from 3 days prior to injection of the tracer until adrenal imaging. In the cases with essential hypertension and obesity, both adrenal glands were delineated equally by standard scintigraphy, and in one patient, undergone suppression scintigraphy, the uptake of 131I-adosterol by both glands were completely inhibited by dexamethasone administration. In primary aldosteronism, six of the 9 patients demonstrated the increased radioactivity in one side, and were diagnosed as aldosteronoma. In 3 cases, failed to show the lesions on standard scintigraphy, the lesions could be detected by suppression scintigraphy, and aldosteronomas measuring 1 x 1 x 0.7, 2 x 2 x 1 and 1.7 x 1.5 x 0.8 cm were confirmed by operation. In Cushing's syndrome, standard scintigraphy could easily distinguish between adenoma (one case) and bilateral hyperplasia (4 cases). Adrenal scintigraphy was also a useful method in order to assess the effect of pituitary irradiation therapy in the case of hyperplasia. In pheochromocytoma and retroperitoneal tumor, the side of the lesion was identified by the absence of a functioning gland. Suppression scintigraphy was particularly useful in detecting the localization of the small tumor in primary aldosteronism. (auth.)

  12. Scintigraphy and venous sampling in endocrine adrenal diseases. Clinical results in 85 patients

    International Nuclear Information System (INIS)

    The results obtained by adrenal scanning and venous sampling in 85 patients affected by various forms of adrenal pathology are reported and discussed. Pheochromocytoma rarely needs venous catheterization and blood sampling, since arteriography is almost always capable to visualize it. Scintigraphy alone is generally accurate enough to distinguish between bilateral hyperplasia and tumors in Cushing's and adrenogenital syndromes (100% of personal observations); only a tumoral situation benefits by venous catheterization. Blood samples and venography must be preceded by scintigraphy in Conn's syndrome

  15. Selenium-75-cholesterol imaging and computed tomography of the adrenal glands in differentiating the cause of Cushing's syndrome

    International Nuclear Information System (INIS)

    Measurement of 75Se-cholesterol (Scintadren) uptake and computed tomography (CT) of the adrenal glands were compared as a means of differentiating the cause of Cushing's syndrome in 11 patients over a 2-year period. Quantitative Scintadren imaging differentiated adrenocorticotrophic hormone (ACTH)-dependent disease from local adrenocortical lesions as the cause of Cushing's syndrome in all the patients studied. CT of the adrenal glands rapidly and accurately detected the adrenal mass lesions in 2 cases and was effective in documenting bilateral hyperplasia due to ectopic ACTH-dependent disease. However, in entopic ACTH (pituitary)-dependent disease the adrenal glands were of normal thickness in all but 2 patients, who had bilateral hyperplasia. Scintadren imaging and CT are useful non-invasive procedures for differentiating local adrenal disease from ACTH-dependent disease as the cause of Cushing's syndrome and should be the initial investigations once a firm clinical and biochemical diagnosis of Cushing's syndrome has been made

  16. Effect of different types of stress on adrenal gland parameters and adrenal hormones in the blood serum of male Wistar rats

    Directory of Open Access Journals (Sweden)

    Adžić M.

    2009-01-01

    Full Text Available In the present study, we examined gross changes in the mass of whole adrenal glands and that of the adrenal cortex and medulla in mature male Wistar rats subjected to three different stress types: acute, chronic, and combined, i.e., chronic followed by acute stress. These parameters were correlated with adrenal activity as judged from serum levels of corticosterone and catecholamine, respectively, as well as with serum levels of ACTH and glucose. Under all three conditions, we observed bilaterally asymmetric and stress-type-independent hypertrophy of whole adrenals, as well as adrenal cortices and medullas. Under acute and combined stress, adrenal hypertrophy was followed by increase of adrenal hormones in the blood serum. However, under chronic stress, both cortical and medullar activities as judged from low or unaltered levels of the respective hormones and glucose were compromised and disconnected from the input signal of ACTH. Since all of the studied adrenal activities could be restored by subsequent acute stress, it is concluded that chronic isolation can be viewed as partly maladaptive stress with characteristics resembling stress resistance rather than the stress exhaustion stage of the general adaptation syndrome.

    Beckwith-Wiedemann syndrome (BWS) is an overgrowth syndrome associated with increased risk to develop malignancies including adrenocortical carcinoma. Ovarian thecal metaplasia of the adrenal gland is a rare tumor-like mesenchymal lesion in BWS patients that lacks detailed radiological description. We report a 17-year-old female patient with BWS, associated with bilateral Wilms tumor, hepatic hemangiomatosis, pancreatic neuroendocrine tumor, and a phyllodes tumor of the right breast. Surveillance abdominal ultrasound identified a right adrenal mass that was further characterized by computed tomography and magnetic resonance imaging. Radiologically, this mass displayed features that overlap with adrenocortical carcinoma and pheochromocytoma but after pathological examination this proved to be an ovarian thecal metaplasia of the adrenal gland. Adrenal masses in BWS should raise the suspicion for adrenocortical carcinoma though other adrenal tumors including ovarian thecal metaplasia can be seen in these patients. PMID:25550997

  20. MR differentiation of adrenal masses

    International Nuclear Information System (INIS)

    Introduction of computed tomography have resulted in the identification during life of clinically silent adrenal masses as small as 5 mm in diameter in from 1-10% of patients studied for reasons other than suspected adrenal disease. MRI enables differentiation between benign (adrenal adenoma) and malignant adrenal masses (primary or metastatic). This discrimination is based on T2 weighted images (specificity about 70%), and enhancement patterns in dynamic study after administration of contrast agent (specificity about 90%). The most specific (above 90%) is, recently employed to examination of adrenal masses, chemical shift imaging, which determines the content of fat in the lesion. Pheochromocytoma has characteristic appearance on MRI, which enables differentiation from adrenal adenoma with specificity about 95%. MRI of adrenal masses has been dynamically developing, enabling noninvasive, more and more specific differentiation. (author)

    Full Text Available Background: Adrenal masses are usually discovered incidentally (IAM during abdominal computed tomography (CT. Aims: We aimed to describe the prevalence, management, and outcome of incidentally discovered adrenal mass on radiological investigation. Materials and Methods: A retrospective analysis was conducted to look for IAM identified by abdominal CT performed for other reasons between 2004 and 2008 and were followed for 4 years. IAM patients with known malignancy or clinically evident adrenal disease or overt disease originally missed due to insufficient clinical examination were excluded. Results: A total of 13,115 patients underwent abdominal CT, of which 136 were identified with adrenal mass (69 males and 67 females. Overall, 84 patients had benign IAM and six had primary adrenal carcinoma (all had tumor size ≥4 cm and five were males. Hormonal evaluation was performed in 80 cases, which revealed hypersecretion in 10 cases (six had Conn′s syndrome and four had pheochromocytoma. Males had higher frequency of right-sided IAMs; whereas, left-sided IAM swere more common among females (P = 0.02. Seven patients underwent surgery and all were males (one Conn′s syndrome, one pheochromocytoma, three primary adrenal adenocarcinoma, one benign nonfunctional adenoma, and one metastatic tumor. Only one patient died due to brain metastasis. Conclusion: The overall prevalence of adrenal incidentaloma is 1% in Qatar. Unfortunately, hormonal evaluation, surgical referral, and follow-up are not appropriate in this study. Moreover, screening of IAM warrants more attention to rule out malignancy. This work could be of value as a local auditing for the current management.

  2. Evaluation of Adrenal Masses in Lung Cancer Patients Using F 18 FDG PET/CT

    International Nuclear Information System (INIS)

    The aim of this study was to assess the diagnostic efficacy of PET/CT using various parameters for the characterization of adrenal nodules in lung cancer patients. Sixty one adrenal nodules in 51 lung cancer patients were evaluated. The final diagnosis was based on histology (n=2) or imaging follow up (n=59, range of follow up: 7-57 months, median 27 months). Each adrenal nodule was analyzed using four parameters of PET/CT: the maximum standardized uptake value (SUVmax), the adrenal nodule/liver ratio of the SUV (SUV ratio), Hounsfield units (HU) and size. The optimal cutoff of each parameter for the identification of metastatic nodule was determined by ROC analysis and then the diagnostic efficacy was compared among the parameters. Of the 61 adrenal nodules, 45 (73%) were considered metastasis. The optimal cutoff values of the parameters were SUVmax>2.7, SUV radio>1.3, HU>18 and size>20mm, respectively. The sensitivity, specificity and accuracy by SUVmax>2.7 were 88.9%, 87.5% and 88.5%, respectively. The combination of SUV ratio>1.3 and HU>18 had sensitivity of 97.7%, specificity of 81.2% and accuracy of 93.4% to predict adrenal metastasis in patients with lung cancer. SUV ratio from F 18 FDG PET/CT could identify the adrenal metastasis in lung cancer patients. The combination of SUV ratio and HU can improve the accuracy of differentiating benign and metastatic adrenal lesions in lung cancer patients

    Full Text Available Presented modern literature data on the features of the pathogenesis, course, clinical and morphological expression and tumor characteristics, parameters and nodal metastasis of hematogenous bilateral breast cancer. Highlight the results of domestic and foreign studies in recent years to determine the prognostic factors and recurrence of synchronous and metachronous bilateral breast cancer. It was revealed that the frequency of bilateral breast tumor lesions varies widely, ranging from 0.1 to 20%, with metachronous tumors recorded significantly higher (69.6% than the synchronous (22.7%. The probability of occurrence of metachronous breast cancer is higher in women with a family history, as well as if they have a gene mutation BRCA-1. Found that the most common histological type of breast tumor with bilateral lesions is invasive ductal. However, the incidence of invasive lobular cancer and non-invasive lobular cancer is slightly higher among synchronous bilateral cancer compared with unilateral disease. Studies have shown that in a double-sided synchronous breast cancer tumor, as a rule, has a lower degree of differentiation, and the higher the expression level of estrogen receptors and progesterone receptors. Relevance of the issue because the identification of patterns in the study of lymphatic and hematogenous features bilateral metastasis of mammary tumors provides a basis for speculation about the differences in the progression of neoplastic disease in these groups and is a cause for further detailed research in this area to identify and evaluate the prognosis and also the choice of tactics of such patients.

  5. Clinical value of isotope methods in adrenal morphology investigations

    International Nuclear Information System (INIS)

    In the years 1976-1980 in 105 patients 124 adrenal scintigrams were obtained, including 50 in patients with primary hyperaldosteronism syndrome, 27 with Cushings syndrome, 8 after bilateral total adrenalectomy, 4 with adrenal virilizing tumours, 6 with phaeochromocytoma, 10 with normal adrenal function. The results of scintigraphy were compared with those of arteriography, phlebography, computer tomography and postoperative findings. The clinical value of scintigraphy was found to be greatest in cases of adrenocortical disease. In cases of phaeochromocytoma isotope angioscintigraphy is a useful method for localizing the tumour since it makes possible demonstration of the vascular bed of the tumour. A close correlation was demonstrated between the results of scintigraphy and those of computer tomography. In the group of 27 patients treated surgically for adrenocortical disease in 87% of cases an agreement was found between the results of scintigraphy and the result of the operation. For different adrenocortical diseases this per cent was: 77% for Cushings syndrome, 91% for primary hyperaldosteronism, 100% for adrenal virilizing tumours. The study showed that adrenal scintigraphy is a very valuable diagnostic method of high clinical usefulness in adrenocortical diseases. (author)

  8. Differential diagnosis of incidentally detected adrenal masses revealed on routine abdominal CT

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to compare CT findings of adrenal incidentalomas with a definitive histological diagnosis in order to establish CT features characteristic for individual types of lesions. Patients and methods: The retrospective study comprised of patients with adrenal lesions detected on abdominal CT. The patients with these incidental findings subsequently underwent adrenalectomy. The adrenalectomy was followed by a histological assessment of the expansion process. The study consisted of 62 adrenal expansions found in 55 patients (in seven patients bilateral lesions were found). According to the definitive histological diagnosis after adrenalectomy, the lesions were divided into the following six groups: primary adrenocortical carcinoma (n = 4), metastasis (n = 7), adrenocortical adenoma (n = 37), pheochromocytoma (n = 9), myelolipoma (n = 2), and others (n = 3). CT observations were categorized as follows: size, shape, margins, density, side of the expansion, homogeneous or heterogeneous density before and after contrast application, presence of central hypodensity, presence of central calcifications and fat deposits. Statistical analysis was carried out using the χ2-test, Kruskal-Wallis test and Mann-Whitney test. To estimate the differences between the subgroups, the t-test was used. For the evaluation of the mutual relations of maximum size, mean size, and volume, regression analysis (coefficient of determination R2) was used. Results: The correlation and regression analysis suggest that there will be no statistically significant error if the maximum size measurements are used instead of the mean size or volume measurements of the lesion. Sensitivity, specificity, accuracy, positive predictive value, negative predictive value for distinguishing adenomas and non-adenomas using a cut-off diameter of 41.5 mm were 81.1%, 70.0%, 77.2%, 83.3%, 66.7%, respectively; using the non-contrast density threshold of 23 HU, they were 89.2%, 100%, 93%, 100

    A rare case of metastatic hepatocellular carcinoma (HCC) of the maxillary sinus in a 67-year-old man is reported along with the findings at autopsy. A fine needle aspiration biopsy specimen revealed a characteristic tumour structure resembling primary HCC. At autopsy, metastatic lesions were recognized in the bilateral adrenals, spleen, sternum, vertebrae and lymph node at the lesser curvature of the stomach, but not in the lung, suggesting that the HCC had metastasized to the maxillary sinus via the plexus venous vertebralis and/or the azygos vein, or lymph duct. In our reviewed 29 cases of metastatic HCC in the oro-maxillofacial region, most patients were men in the 50- to 70-year age range. At least 11 cases did not have lung metastasis, and in 18, metastasis to the oro-maxillofacial region was the first sign of HCC. One should be aware of the possibility to encounter the oral lesion as first sign of metastatic HCC. PMID:12653243

    Full Text Available Primary adrenal mesenchymal tumors are exceptionally rare. Diagnosis is based entirely on histological and immunohistochemical evaluation which is indispensable not only for determining tumor type but also for predicting biological behavior. We report a rare case of primary leiomyosarcoma of the left adrenal gland, in a 60 year old woman who presented with flank pain. Computed tomography revealed a well defined left adrenal tumor which was surgically resected. Histological examination of the tumor showed malignant spindle cells in interlacing fascicles and whorls. Nuclear pleomorphism, tumor giant cells and abnormal mitotic figures were seen. On immunohistochemistry, the tumor cells showed reactivity for smooth muscle actin, vimentin and desmin; and were negative for cytokeratin, S100 protein, CD117 and HMB-45. A diagnosis of primary adrenal leiomyosarcoma was offered. Postoperative recovery of the patient was uneventful and the patient was symptom free with no evidence of tumor metastasis or recurrence 21 months after surgery.

    Full Text Available Leiomyosarcoma of the adrenal gland is extremely rare in the literature. We present a patient with an adrenal leiomyosarcoma originating from the adrenal vein, the pathologic findings and management. A 66-year-old man who was a hepatitis B virus carrier was found to have a huge left suprarenal mass on sonography and computed axial tomography. A huge tumor in the left suprarenal area with a markedly engorged adrenal vein was found during an adrenalectomy. The tumor thrombus extended into the renal vein, close to the inferior vena cava. The left adrenal gland with the whole tumor thrombus was removed completely. Microscopically, the adrenal gland was compressed but not invaded by the spindle cell tumor, which was composed of interlacing fascicles of neoplastic smooth muscle cells. The tumor was localized within the adrenal vein and arose from the venous wall. The patient had no local recurrence for 18 months after en bloc excision of the tumor. We suggest that en bloc excision with a clear and adequate surgical margin is the most important cure procedure for adrenal leiomyosarcoma.

  15. Computed tomographic findings of radiation-induced acute adrenal injury with associated radiation nephropathy: a case report

    International Nuclear Information System (INIS)

    Radiation nephropathy was first recognized in 1906. The kidney is a radiosensitive organ with a tolerance dose (5% complications in 5 years) of 20 Gray. The imaging findings of acute and chronic radiation induced renal injury are previously described. Radiation-induced adrenal injury, to our knowledge, has not been described in the literature. Unlike the kidneys and other upper abdominal organs, the adrenal glands are traditionally thought to be radio-resistant, protected from radiation-induced injury by proximity to adjacent organs and by the adrenal medulla which reportedly has increased radio-resistance. We present the computed tomographic imaging findings of a patient with acute radiation induced adrenal injury which resulted in adrenal insufficiency following radiotherapy of an adjacent thecal metastasis

    Purpose. To evaluate the diagnosis and treatment of adrenal incidentalomas. Methods. One hundred and twenty-six patients with incidentalomas were analyzed, among them 98 underwent operation. Results. Eighty-eight of the adrenal incidentalomas were discovered by ultrasound. Of all the types of adrenal incidentalomas, 52 (41.3%) of them were adenomas; 43 (34.1%) were hypersecretory adrenal tumors, including 29 pheochromocytomas, 9 primary aldosteronisms, 1 adrenogenitol syndrome combined with adrenal adenoma, 2 Cushing's syndrome combined with adenomas and 2 Cushing's syndrome combined with nodular hyperplasias. All nonhypersecretory adrenal adenomas were under 6 cm, and all adrenal carcinomas were above 6 cm.Conclusions. To search for hypersecretory adrenal tumors and to detect malignant adrenal tumors are quite essential in the process of diagnosing adrenal incidentalomas. For nonhypersecretory adrenal adenomas, the size of tumor is the most important index in determining whether the tumor is benign or malignant and whether the tumor needs to be treated with operation.

    The adrenal gland is the second most common site of metastasis from a hepatocellular carcinoma (HCC). Radiofrequency ablation (RFA) for these tumors has been reported to be a potentially effective alternative to an adrenalectomy, especially for inoperable patients. However, for intermediate or large adrenal tumors, combination therapy of transarterial chemoembolization (TACE) and RFA can be attempted as it may reduce the heat sink effect. A 74-year-old patient presented with abdominal discomfort. Abdominal CT images revealed a 5.0 cm sized right adrenal mass. A percutaneous biopsy of the adrenal mass revealed a metastatic hepatocellular carcinoma. TACE was performed on the adrenal mass. However, a one-month follow-up CT image revealed a residual viable tumor. RFA was performed for the adrenal tumor six weeks after the TACE. No procedure-related major complications were noted. The serum alpha-fetoprotein level had also been normalized after the treatment, and 10-month follow-up CT images showed no definite evidence of viable adrenal tumor.

    One of the rarest situations regarding an adrenal incidentaloma is an adrenal cyst. We present the case of a 61-year-old male patient diagnosed with peritonitis. During surgery, a right adrenal tumor of 2 cm is discovered. The patient was referred to endocrinology. 6 months later the diameter of the tumor is 7 times bigger than the initial stage. It has no secretory phenotype, except for the small increase of serum aldosterone and the 24-h 17-ketosteroids. Open right adrenalectomy is performed and a cyst of 15 cm is removed. The evolution after surgery is good. The pathological exam reveals an adrenal cyst with calcifications and osteoid metaplasia. The immunohistochemistry showed a positive reaction for CD34 and ACT in the vessels and VIM in the stroma. The adrenal cysts are not frequent and represent a challenge regarding the preoperative diagnostic and surgical procedure of resection. The pathological exam highlights the major aspects.

  19. US-guided fine-needle biopsy (FNB) of adrenal masses in the staging of lung tumors

    International Nuclear Information System (INIS)

    In patients with lung tumors adrenal masses can represent metastases, hyperplasia, adenoma or other benign lesions, most of which can be asymptomatic. Altough the sensibility of US and CT in the diagnosis of adrenal metastases is very high, their specificity is somehow less satisfactory. The risk of overstaging operable pulmonary tumors is therefore present. US-guided FNB can yield material enough for cytologic and, in some cases, histologic evaluation, thus offering a reliable solution to the clinical problem in selected cases. The experience with US-guided percutaneous mono or bilateral FNB of adrenal masses with Chiba and/or Otto needle in 14 patients with pulmonary neoplasms is reported. The use of Otto needle is suggested in the largest adrenal masses or when histology of the primary neoplasm is unknowen. Bilateral cytological FNB is suggested in borderline lesions

  20. Ultrasonographic detection of adrenal gland tumor and ureterolithiasis in a guinea pig

    International Nuclear Information System (INIS)

    A 5-year-old guinea pig was presented to the University of Berne Small Animal Radiology Department for an ultrasound examination of the abdomen to confirm a suspected diagnosis of Cushing's syndrome. The patient had bilateral alopecia, was apathic and obese. Ultrasonographically, a tumor of the left adrenal gland, obstruction of the left ureter by an ureterolith, as well as hydronephrosis of the left kidney were detected. During surgery to relieve the ureteral obstruction the adrenal gland tumor was removed. The guinea pig died post-operatively due to blood loss. The left adrenal gland tumor was found histopathologically to be an adenoma and the right adrenal gland also had multiple small adenomas, but grossly appeared normal. The ureterolith was analyzed and found by x-ray diffraction to consist of calcium carbonate

    Non-invasive characterization of adrenal lesions is a commonly encountered diagnostic challenge. Characteristic clinical and correlative imaging findings may assist in only arriving at a probable diagnosis. Currently, (18)F-FDG PET/CT is considered to provide the most comprehensive imaging information. We here present a case of bilateral adrenal tuberculosis that highlights the need for caution during the interpretation of (18)F-FDG PET/CT and also the need to suggest histopathological correlation.

  3. Adrenal scintigraphy with 131I-19-iodocholesterol in the diagnosis of Cushing's syndrome associated with adrenal tumor

    International Nuclear Information System (INIS)

    Seven patients with Cushing's syndrome secondary to adrenocortial tumors were studied using 131I-19-iodocholesterol. The diagnoses of all cases were verified histologically. In three cases with adenoma the uptake of the tracer was in the tumor only, while the two patients with adrenocortical carcinoma failed to show adrenal accumulation of the labelled compound. In two patients there was a hyperplasia-like scintigraphic pattern, while the stimulation and suppression biochemical tests suggested adrenal tumor. One of these cases was verified as a mixed form (adenoma plus hyperplasia), and the tumor bearing gland was significantly larger on the scan which helped the preoperative localization. In the other case, verified as bilateral multiple adrenocortical adenomas, the autonomus function of both adrenals was proved by dexamethasone suppression scanning. It seems reasonable to use the latter as an adjunctive diagnostic procedure in patients where there is a discrepancy between the standard scintiscan and the biochemical indexes of adrenal hyperfunction.

  4. MR imaging of adrenal masses

    International Nuclear Information System (INIS)

    Signal intensity (SI) ratios and T2 values of 23 adrenal masses were analyzed using 1. 5 tesla MR imaging system to evaluate these capabilities for tissue characterization. They included 11 nonhyperfunctioning adenomas, 4 hyperfunctioning adenomas, 1 nodular hyperplasia, 3 metastatic tumors, and 4 pheochromocytomas. SI ratios of adrenal/fat, adrenal/liver, and adrenal/muscle on both T1-weighted images (WI) and T2-WI were obtained in each adrenal mass. The T2 values of adrenal masses were calculated with two echo sequences. In results, SI ratios on both T1-WI and T2-WI were not useful in the differentiation of metastatic tumors from adenomas. The calculated T2 value was more relaible. All 14 masses with a T2 value less than 60 msec were adenomas, and 4 masses with a T2 value of 60 msec or more included one adenoma and 3 metastatic tumors. The T2 value of 1 nodular hyperplasia was 58 msec and the T2 values of all 4 pheochromocytomas were over 70 msec. There were no significant differences in SI ratios and T2 value between nonhyperfunctioning and hyperfunctioning adenomas. Therefore, the T2 value is more accurate than SI ratios for tissue characterization of adrenal masses at 1. 5 tesla. Although the T2 value correlated well with the size of mass, whether it depends on mass size or tissue character remains controversial. (author)

  5. Adrenal hemorrhage following liver transplantation

    International Nuclear Information System (INIS)

    Liver transplantation ordinarily entails sacrificing the right adrenal vein. In seven patients (about 2% of liver recipients) ultrasound (US) and/or computed tomography (CT) revealed right adrenal hemorrhages, detected an average of 6 days postoperatively. Hemorrhages on US scans were initially echogenic and became hypoechoic or anechoic with time. On CT scans, most were centrally hypodense with a peripheral rim of higher attenuation. No calcification developed. Hemorrhages were ovoid in shape and 2.5-4.5 cm in maximum diameter, and they resolved in 3-11 weeks in transplant survivors. These adrenal hemorrhages should be recognized and documented but usually should be left alone; complications are rare

  6. Extra adrenal retroperitoneal paragangliomas

    International Nuclear Information System (INIS)

    Extra adrenal retroperitoneal paragangliomas are very uncommon tumors that are easily diagnosed on the basis of clinical signs when they are functioning. However, imaging techniques are indispensable tools for locating them for surgical treatment. Our objective is to compare the CT and MR findings to determine, in the latter case, the sequences of choice for this purpose, as well as the advantages and disadvantages of each. We studied retrospectively six patients by CT, ultrasonography, metaiodobenzyl guanidine (MIBG) scintipgraphy and MR, evaluating the diagnostic value of these procedures. CT was found to be useful because of its diagnostic sensitivity. The strong MR signal that characterizes these tumors and its spatial resolution make this test indispensable for the detection of small paragangliomas and those difficult to located by CT. We consider MR to be the technique of choice because of its marked sensitivity and multiplanar capacity for the diagnosis of tumors that are specially difficult because of their size or location.

    The management of congenital adrenal hyperplasia involves suppression of adrenal androgen production, in addition to treatment of adrenal insufficiency. Management of adolescents with congenital adrenal hyperplasia is especially challenging because changes in the hormonal milieu during puberty can lead to inadequate suppression of adrenal androgens, psychosocial issues often affect adherence to medical therapy, and sexual function plays a major part in adolescence and young adulthood.

  9. MR imaging in adrenal diseases

    International Nuclear Information System (INIS)

    Twenty-five patients affected by adrenal glands pathology underwent CT and MRI: 6 nonfuctioning adenomas, 2 Cushing's adenomas, 2 Conn's adenomas, 6 metastases, 3 cystis, 2 carcinomas (Cushing's syndrome), 1 Lymphoma and 3 pheochromocytomas. Diagnosis was subsequently confirmed either at surgery, or autopsy, or with needle biopsy. In all cases normal adrenal glands and pathological lesions were showed by MRI. T1 signal intensity and mass diameter were compared with T2 signal intensity, represented by the intensity ratio between the adrenal mass vs normal hepatic parenchyma. MRI signal intensity, usually high in case of malignancy and low in adenomas, shows a mean value which is much wider than that referred to mass diameter evaluation (carcinoma is larger than adenoma); for this reason those findings have proved to be insufficiently accurate for adrenal tissue characterization, even for the evaluation of cysts and pheochromocytomas. In the same cases CT showed higher accuracy

    Substantial evidence shows that the hypophyseal–pituitary–adrenal (HPA) axis and corticosteroids are involved in the process of addiction to a variety of agents, and the adrenal cortex has a key role. In general, plasma concentrations of cortisol (or corticosterone in rats or mice) increase on drug withdrawal in a manner that suggests correlation with the behavioural and symptomatic sequelae both in man and in experimental animals. Corticosteroid levels fall back to normal values in resumptio...

    Full Text Available Adrenocorticotropin (ACTH independent bilateral macronodular adrenal hyperplasia (AIMAH is a rare cause of Cushing´s syndrome, characterized by bilateral adrenal lesions and excess cortisol production despite ACTH suppression. Cortisol synthesis is produced in response to abnormal activation of G-protein- coupled receptors, such as gastric inhibitory peptide, vasopressin, beta adrenergic agonists, LH/hCG and serotonin receptors. The aim of this study was to analyze the expression of glucagon receptors in adrenal glands from an AIMAH patient. A patient with ACTH-independent Cushing´s syndrome and bilateral macronodular adrenal hyperplasia was screened for altered activation of adrenal receptors by physiological (mixed meal and pharmacological (gonadotrophin releasing hormone, ACTH and glucagon tests. The results showed abnormally high levels of serum cortisol after stimulation with glucagon. Hypercortisolism was successfully managed with ketoconazole treatment. Interestingly, a 4-month treatment with a somatostatin analogue (octreotide was also able to reduce cortisol secretion. Finally, Cushing's syndrome was cured after bilateral adrenalectomy. Abnormal mRNA expression for glucagon receptor in the patient´s adrenal glands was observed by Real-Time PCR procedure. These results strongly suggest that the mechanism of AIMAH causing Cushing´s syndrome in this case involves the illicit activation of adrenal glucagon receptors. This is the first case reported of AIMAH associated with ectopic glucagon receptors.La hiperplasia adrenal macronodular bilateral independiente de ACTH (HAMIA es una causa infrecuente de Síndrome de Cushing, caracterizada por lesiones adrenales bilaterales, hipercortisolismo y ACTH plasmática suprimida.

  13. Adrenocortical scintigraphy to evaluate incidental adrenal mass (incidentaloma) discovered on computed tomography

    International Nuclear Information System (INIS)

    To assess the nature of adrenal mass incidentally discovered on computed tomography, adrenocortical scintigraphy with I-131-6 β-iodomethyl-19-norcholest-5(10)-en-3 β-ol (I-131 Adosterol) in 29 patients was retrospectively reviewed. All patients had no clinical symptoms and biochemical evidence of adrenal hyperfunction. Six of them had extraadrenal malignancy. Increased tracer uptake on the side of adrenal mass was observed in 13 patients (concordant group): cortical adenoma in 8, macronodular hyperplasia in 1, no growing tumor in 1, and no further examination in the remaining 3 patients. No cancer patients were included in the concordant group. Symmetric uptake was seen in 9 patients (symmetric group): 1 cortical adenoma and 1 ganglioneuroma, 6 no growing tumor (two of them had malignancy), and no further examination in 1 patient. Decreased uptake was shown in 7 patients (disconcordant group): metastasis in 4, adrenal cyst in 2, and no growing tumor in 1. Adrenocortical scintigraphy was helpful in distinguishing benign functioning adrenal masses from non-functioning adrenal masses such as metastatic tumor and cyst. (author)

    Full Text Available Abstract Renal cell carcinoma constitutes about 3% of adult malignancies. It has a high metastatic potential associated with synchronous or metachronous metastatic disease. Further, it is known to metastasize mainly to the lung, bone, brain, liver, or adrenal glands. In very rare cases it can metastasize to the gallbladder mimicking acute cholecystitis on clinical exam. In this case we present a patient who developed a gallbladder metastasis five years after a renal cell carcinoma mimicking acute cholecystitis.

    Full Text Available We present the diagnostic approach of a patient with adrenal incidentalomas. A 72-year-old African American male had a CT scan of the abdomen showing right and left adrenal masses measuring and , respectively. The patient had negative hormonal workup. The radiologist insisted that the CT findings are consistent with adrenal hyperplasia, and therefore he underwent ACTH stimulation to rule out late-onset congenital adrenal hyperplasia (CAH. The stimulation test revealed that 17-hydroxyprogesterone and 11-deoxycortisol increased to levels high enough to confirm CAH, but cortisol had exaggerated response as well, thus making the diagnosis of CAH unlikely where metabolism is shifted to precursors. Subsequently, the patient underwent screening for Cushing's syndrome (CS with a dexamethasone suppression test. Patient failed the suppresion test, raising the issue for subclinical CS (SCS, likely due to ACTH-independent macronodular adrenal hyperplasia. Our patient had been diagnosed with MGUS and so far there are only 3 case reports of extramedullary plasmacytoma arising from the adrenals. One was bilateral and one had functional abnormalities. Our differential diagnosis includes subclinical CS with aberrant receptors versus a functioning extramedullary plasmacytoma.

  17. Decoding Melanoma Metastasis

    International Nuclear Information System (INIS)

    Metastasis accounts for the vast majority of morbidity and mortality associated with melanoma. Evidence suggests melanoma has a predilection for metastasis to particular organs. Experimental analyses have begun to shed light on the mechanisms regulating melanoma metastasis and organ specificity, but these analyses are complicated by observations of metastatic dormancy and dissemination of melanocytes that are not yet fully malignant. Additionally, tumor extrinsic factors in the microenvironment, both at the site of the primary tumor and the site of metastasis, play important roles in mediating the metastatic process. As metastasis research moves forward, paradigms explaining melanoma metastasis as a step-wise process must also reflect the temporal complexity and heterogeneity in progression of this disease. Genetic drivers of melanoma as well as extrinsic regulators of disease spread, particularly those that mediate metastasis to specific organs, must also be incorporated into newer models of melanoma metastasis

  19. Radiological diagnosis of adrenal lesions

    International Nuclear Information System (INIS)

    Among all the radiological examination techniques, CT is today, besides scintigraphy, the method of choice as far as the detection of functional adrenal lesions is concerned. In primary aldosteronism, CT classification of the syndrome is based on the detection of an adenoma which can be reliably detected in adenoma sizes up to 8-10 mm. Thus, 70 to 80% of Conn's syndromes can be classified. In adrenal Cushing's syndrome, the distinction between adenoma and carcinoma of the adrenal gland is up to CT and can usually be easily made due to the characteristic morphology of each type of lesion. In case of a typcial adrenal or juxtaadrenal tumor location, detection of a pheochromocytoma is likewise easy. In ectopic and multiple pheochromocytomas or such as occur as part of a MEN-syndrome, the situation is quite different. If lesions of the adrenal gland are found by accident in examinations otherwise indicated, the question arises whether the process is malignant or benign. In this respect, all the traditional imaging methods, including CT, involve a considerable factor or uncertainity, especially if a malignant tumor is anamnestically known and the question of metastases arises. According to recent information, MR-imaging seems to be advantageous concerning this difficult differential diagnosis. (orig.)

  20. Rare and severe complications of congenital adrenal hyperplasia due to 21-hydroxylase deficiency: a case report

    Ferreira Florbela

    2013-02-01

    Full Text Available Abstract Introduction We report the case of a patient with classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency who presented with unusual anatomical and biochemical features, namely massively enlarged adrenal glands, adrenogenital rest tissue and an unexpected endocrine profile. The contribution of the adrenocortical cells in the adrenals and testicles was determined by a cosyntropin stimulation test before and after adrenalectomy. To the best of our knowledge this is the first report of such a case in the literature. Case presentation A 35-year-old Caucasian man was admitted to the emergency room with an Addisonian crisis. He had been diagnosed with congenital adrenal hyperplasia in the neonatal period. He acknowledged poor adherence to treatment and irregular medical assistance. Physical examination revealed marked cutaneous and gingival hyperpigmentation, hypotension, and hard nodules in the upper pole of both testicles. Blood analysis showed mild anemia and hyponatremia and no evidence of acute infection. Endocrine evaluation showed very low cortisol levels, low dehydroepiandrosterone-sulfate and elevated corticotropin, 11-deoxycortisol and delta-4-androstenedione. The concentration of 17-hydroxyprogesterone was 20,400ng/dL. After the cosyntropin stimulation test the pattern was similar and there was no significant increase in cortisol or 17-hydroxyprogesterone. The abdominal computed tomography scan revealed grossly enlarged and heterogeneous adrenal glands (left, 12cm; and right, six cm. A bilateral adrenalectomy was performed and pathologic examination revealed adrenal myelolipomas with nodular cortical hyperplasia. The sonogram showed bilateral heterogeneous masses on the upper pole of both testes which corresponded to the nodular hyperplasia of adrenal rest tissues. The genetic study revealed compound heterozigoty (mutations R124H and R356W, suggestive of a phenotypically moderate disease. We performed a

  1. Metastasis features of 546 patients with stage IV non-small cell lung cancer at first visit and the significance in radiotherapy

    International Nuclear Information System (INIS)

    Objective: To investigate the clinical metastasis features and the possibility of 3 dimensional radiotherapy of stage IV non-small cell lung cancer (NSCLC). Methods: The clinical materials of 546 patients with stage IV NSCLC and the relationship b T and N stage and metastasis were retrospectively analyzed. Results In 546 patients with stage IV NSCLC, the number with bone metastasis was 294, the number with brain metastasis was 167, the number with lung metastasis was 137, the number with liver metastasis was 79, the number with adrenal gland metastasis was 66, 37 with lymph node metastasis, 35 with subcutaneous metastasis and 10 with other organ metastasis. The number with single organ metastasis was 379 (69.4%) ,in which 37.7% with bone metastasis, 19.8% with brain metastasis, 16.9% with lung metastasis, 7.4% with liver metastasis, 7.4% with adrenal gland metastasis, 4.5% with lymph node metastasis, 5.5% with subcutaneous metastasis and 0.8% with other organ metastasis. The bone metastasis probability of T3+4 patient was similar with T1+2 (69.4%, 30.6%, χ2 = 7.65, P = 0.067), but N2+3 patient was more than N0+1 (69.7%, 30.3%, χ2 = 7.89, P = 0.044). The brain metastasis probability of T3+4 patient was more than T1+2 (70.7%, 29.3%, χ2 = 10.64, P = 0.018), but N2+3 patient was similar with N0+1 (54.5%, 45.5%, χ2 = 7.14, P = 0.079), and N1+3+3 patient was more than N0 (86.8%, 13.2%, χ2 = 10.26, P = 0.024). Conclusions: In 546 patients with stage IV NSCLC, the most common metastatic organ is bone, the second is brain, the third is lung, the forth is liver, followed by adrenal gland; single organ metastasis is more common than multiple organ metastasis. The later the T stage is, the more severe is the metastasis. Through 3 dimensional radiotherapy, not only the quality of life of some stage IV patients is improved, but also the survival time was prolonged observably. (authors)

  2. Bilateral adrenalectomy for Cushing's syndrome: Pros and cons

    2015-01-01

    Full Text Available Aim: To assess the outcome of patients undergoing bilateral adrenalectomy for Cushing's syndrome (CS. Methods: All patients who underwent bilateral adrenalectomy for CS at the Department of Endocrine Surgery, Sanjay Gandhi Postgraduate Institute of Medical Sciences hospital between 1991 and 2013 were included. Medical records were reviewed to obtain patient characteristics and follow-up data. Results: Twenty-seven patients were studied. Mean age was 28.74 ± 12.95 years (range 9–60, male:female ratio was 1.7:1. About half that is, 48.19% were of Cushing's disease (failed trans-sphenoidal surgery [TSS], 37.04% were of ectopic CS (ECS, and 14.81% were of CS due to bilateral adrenal pathology. Median follow-up period was 80.5 months. Before surgery, 74.1% patients had body mass index > which after surgery declined to <25 in 75% of them. Hypertension was present in 85.2% and after surgery resolved in 40%. Diabetes mellitus was present in 44.4% and after surgery resolved in 33% of them. Hirsutism and proximal muscle weakness were present in 55.6% and 70.4% patients, respectively, and after surgery improved markedly in all patients. Adrenal crisis developed in 36.3% and Nelson's syndrome in 41.7% patients during follow-up. Three patients died in perioperative period while three succumbed to the disease during follow-up. Two patients developed recurrence of endogenous cortisol production during the follow-up period. Conclusions: Bilateral adrenalectomy is a valid treatment option for palliating severe symptoms in Pituitary Cushing's with failed TSS and unlocalized ECS but the procedure is curative for CS due to bilateral adrenal disease. Overall morbidity and mortality is higher than other endocrine operations. Co-morbidities tend to be more severe and are a risk factor for mortality during the time patient survives.

    A rare cause for rapid adrenal enlargement is adrenal oncocytoma of uncertain malignant potential. A full biochemical evaluation is warranted to screen secreting adrenal adenomas as well as to evaluate adrenal cortical carcinoma. Careful pathologic evaluation is required as the diagnosis of AOC cannot be made by imaging. PMID:27014458

    Full Text Available Context: Anatomical localization of pituitary adenoma can be challenging in adrenocorticotropic hormone (ACTH-dependent Cushing's syndrome, and bilateral inferior petrosal sinus sampling (BIPSS is considered gold standard in this regard. Stimulation using corticotrophin-releasing hormone (CRH improves the sensitivity of BIPSS, however, same is not easily available in India. Therefore, we undertook this study of BIPPS using vasopressin as agent for stimulation owing to its ability to stimulate V3 receptors present on corticotrophs. Aims: To study the tumor localization and lateralization in difficult to localize cases of ACTH-dependent Cushing's syndrome by bilateral inferior petrosal sinus sampling using vasopressin for corticotroph stimulation. Settings and Design: Prospective observational study. Subjects and Methods: Six patients (5 females meeting inclusion criteria underwent BIPSS using vasopressin for stimulation. Results: All six patients had nonsuppressible overnight and low dose dexamethasone suppression test with elevated plasma ACTH levels suggestive of ACTH-dependent Cushing's syndrome. High dose dexamethasone suppression test showed suppressible cortisol in two cases, and microadenoma was seen in two patients on magnetic resonance imaging pituitary. Contrast enhanced computed tomography of the abdomen showed left adrenal hyperplasia in one case and anterior mediastinal mass with bilateral adrenal hyperplasia another. Using BIPSS four patients were classified as having Cushing's disease that was confirmed histopathologically following surgery. Of the remaining two, one had primary pigmented nodular adrenocortical disease, and another had thymic carcinoid with ectopic ACTH production as the cause of Cushing's syndrome. No serious adverse events were noted. Conclusions: Vasopressin may be used instead of CRH and desmopressin for stimulation in BIPSS.

    Full Text Available We report a case of unilateral hyperplasia of the adrenal medulla. The patient showed clinical features suggestive of pheochromocytoma. Removal of the hyperplastic adrenal gland resulted in complete disappearance of all prior symptoms, decrease of the plasma and urinary catecolamine levels and no high uptake in [133I] metaiodobenzylguanidine scintigraphy. A histological study revealed diffuse hyperplasia of the adrenal medulla. Up to now, there are relatively few reports of adrenal medullary hyperplasia in English literatures.

  9. Control of adrenal androgen production.

    Science.gov (United States)

    Odell, W D; Parker, L N

    The major adrenal androgens are dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulphate (DHEAS) and androstenedione (delta 4). Studies by Cutler et al in 1978 demonstrated that these androgens are detectable in blood of all domestic and laboratory animals studied, but that only 4 species show increase in one or more with sexual maturation: rabbit, dog, chimpanzee and man. Studies by Grover and Odell in 1975 show these androgens do not bind to the androgen receptor obtained from rat prostate and thus probably are androgens only by conversion to an active androgen in vivo. Thomas and Oake in 1974 showed human skin converted DHEA to testosterone. The control of adrenal androgen secretion is in part modulated by ACTH. However, other factors or hormones must exist also, for a variety of clinical observations show dissociation in adrenal androgen versus cortisol secretion. Other substances that have been said to be controllers of adrenal androgen secretion include estrogens, prolactin, growth hormone, gonadotropins and lipotropin. None of these appear to be the usual physiological modulator, although under some circumstances each may increase androgen production. Studies from our laboratory using in vivo experiments in the castrate dog and published in 1979 indicated that crude extracts of bovine pituitary contained a substance that either modified ACTH stimulation of adrenal androgen secretion, or stimulated secretion itself - Cortisol Androgen Stimulating Hormone. Parker et al in 1983 showed a 60,000 MW glycoprotein was extractable from human pituitaries, which stimulated DHA secretion by dispersed canine adrenal cells in vitro, but did not stimulate cortisol secretion. This material contained no ACTH by radioimmunoassay. In 1982 Brubaker et al reported a substance was also present in human fetal pituitaries, which stimulated DHA secretion, but did not effect cortisol. PMID:6100259

    A 76-year-old female in whom a renal cell carcinoma (RCC) lesion was resected 19 years previously presented to our hospital with cognitive dysfunction. Magnetic resonance imaging and computed tomography revealed nodules in the brain, lung, adrenal gland and a pelvic osteolytic lesion. To identify the primary cancer site, the present study performed endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of the left adrenal lesion. Consequently, the pathological findings of the tissue obtained by EUS-FNA were similar to those of the previous nephrectomy specimen, revealing that the adrenal lesion was the recurrence of RCC. The majority of the metastatic lesions in the patient were reduced in size by the multiple kinase inhibitor, pazopanib. Contralateral adrenal metastasis of RCC is rare and the use of EUS-FNA in the diagnosis of adrenal lesions remains to be elucidated. This is a rare case of adrenal lesion, diagnosed by EUS-FNA. Therefore, EUS-FNA is considered to be a useful diagnostic modality of adrenal metastases from unidentified primary tumor types. PMID:27073657

  11. Mineralocorticoid hypertension: clinical and laboratory studies with special reference to selective percutaneous venography combined with aldosterone assay in the adrenal venous blood

    International Nuclear Information System (INIS)

    With the purpose of demonstrating the presence of hypertension, hypokalemia and alkalosis were studied. The presence of daily aldosteronism was verified in five patients; the sixth one presented no daily aldosteronism but an increase of 18-OH-DOCA production, an ACTH dependente mineralocorticoid. The presence of tumor (less than 0.9cm) could not be shown in two patients by bilateral selective adrenal venography. The aldosterone assay during catherization of adrenal vein of those patients permitted to determine the tumoral side. Attention must be given to the fact that the blood collection of adrenal vein must always be made during adrenal venography to demonstrate the presence of short unilateral tumor or bilateral disease

  12. Differential diagnosis of adrenal gland masses

    International Nuclear Information System (INIS)

    Computed tomography (CT) and magnetic resonance (MR) imaging are first line modalities in the evaluation of patients with adrenal gland masses, and have the potential to be very accurate for the localization of adrenal gland masses in patients with diseases associated with hyperfunctioning conditions of the adrenal gland. Both CT and MR imaging allow a specific diagnosis of acute adrenal hemorrhage, adrenal myelolipoma, and adrenal cysts. CT is also helpful in the assessment of patients with Addision's disease, particularly the subacute from secondary to granulomatous diseases. Quantitative evaluation of adrenal masses on unenhanced CT scans and/or qualitative analysis on chemical-shift MR imaging have been shown to be accurate in distinguishing adrenal adenomas from non-adenomas. Attenuation of 11 HE or less on unenhanced CT scans and/or signal loss on opposed phase MR images indicate adenoma with a high specificity and acceptable sensitivity. More recently, delayed-enhanced CT has yielded higher sensitivity and specificity values in distinguishing between adrenal adenomas and non-adenomas than both unenhanced CT and chemical-shift MR imaging do. On delayed-enhanced CT scans, adrenal adenomas exhibit a greater washout of contrast material than do adrenal non-adenomas. Therefore, adrenal non-adenomas have significantly higher attenuation than adenomas on delayed-enhanced CT scans obtained at several arbitrarily chosen time points (3-60 min) after the initiation of contrast material administration.

    Thyroparathyroidectomy (TPX) prevents adrenal regeneration hypertension (ARH) in female rats and concomitantly inhibits regeneration of the adrenal cortex. Removal of the thyroid gland plays the major role in preventing ARH inasmuch as parathyroidectomized adrenal-enucleated (PX-AE) rats became hypertensive, whereas thyroparathyroidectomized adrenal-enucleated rats (TPX-AE + PT) did not. Inhibition of adrenocortical regneration by TPX is reflected by a significant decrease in adrenal weight, ...

    International Nuclear Information System (INIS)

    Masses involving the adrenal in the neonate are most commonly due to hemorrhage. The literature involving the neonatal adrenal reflects this propensity. Although there have been reports of newborns with neuroblastoma and other tumors, which are more common in older children, ultrasonographic descriptions of masses involving the adrenal secondary to such tumors are rare. Within a 6-month span we have discovered a clinically unsuspected adrenal carcinoma and adrenal neuroblastoma. (orig.)

    Full Text Available Despite decades of different treatment algorithms, the management of congenital adrenal hyperplasia (CAH remains clinically challenging. This is due to the inherent difficulty of suppressing adrenal androgen production using near physiological dosing of glucocorticoids (GC. As a result, alternating cycles of androgen versus GC excess can occur and may lead to short stature, obesity, virilization, and alterations in puberty. Novel therapeutic alternatives, including new and more physiological means of GC delivery, inhibitors at the level of CRH or ACTH secretion and/or action, as well as “rescue strategies”, such as GnRH analogs, anti-androgens, aromatase inhibitors, and estrogen receptor blockers, are available; many of these agents, however, still require active investigation in CAH. Bilateral adrenalectomy is effective but it is also still an experimental approach. Gene therapy and stem cells, to provide functional adrenal cortical tissue, are at preclinical stage but provide exciting avenues for a potential cure for CAH.

    The Authors report their limited series of neoplasms of the adrenal cortex, and underline the decisive role of the modern diagnostics based on imaging techniques (US--TC--NMR). These, in fact, often allow a good definition also in the non-functioning adrenal masses incidentally discovered (incidentalomas). The authors emphasize the high quality of such diagnostic methods offering a good reliability in discriminating the nature of the adrenal mass. These undeniable diagnostic advantages have a positive impact on the surgical strategy, allowing together with a careful morphological study of the lesion, to program in detail possible demolitive operations. The authors finally underline the importance of the surgical access: they are persuaded the best is the bilateral under-rib incision. This surgical approach assures a complete exploration of the abdominal and pelvic cavity; moreover, it allows to face every complication. PMID:8481276

  1. Magnetic Resonance and adrenal cortex pathology

    International Nuclear Information System (INIS)

    M.R.I. allows a good delineation of adrenals, due to the high contrast with fat and to the use of frontal planes. On post operative adrenal lesions samples the lipid percentages, high in normal and hyperplasic glands, was still high in most benign adenomas, and very low (under 5 %) in adrenal carcinomas. MRI, with Dixon sequence, allows to evaluate this lipid percentage in adrenal lesions. Post-operative controls show a good agreement between in vivo and in vitro measurements. This simple technique should allow to discriminate between malignant and benign adrenal cortex lesions

    Summary Resistant hypertension is often difficult to treat and may be associated with underlying primary aldosteronism (PA). We describe the case of an elderly gentleman who presented with severe and resistant hypertension and was found to have a left adrenal incidentaloma during evaluation but had aldosterone excess secondary to unilateral adrenal hyperplasia (UAH) of the contralateral gland, which needed surgical intervention. A 65-year-old gentleman was evaluated for uncontrolled high blood pressure (BP) in spite of taking four antihypertensive medications. The high BP was confirmed on a 24-h ambulatory reading, and further biochemical evaluation showed an elevated serum aldosterone renin ratio (ARR) (1577 pmol/l per ng per ml per h). Radiological evaluation showed an adrenal nodule (15 mm) in the left adrenal gland but an adrenal vein sampling demonstrated a lateralization towards the opposite site favouring the right adrenal to be the source of excess aldosterone. A laparoscopic right adrenalectomy was performed and the histology of the gland confirmed nodular hyperplasia. Following surgery, the patient's BP improved remarkably although he remained on antihypertensives and under regular endocrine follow-up. PA remains the most common form of secondary and difficult-to-treat hypertension. Investigations may reveal incidental adrenal lesions, which may not be the actual source of excess aldosterone, but UAH may be a contributor and may coexist and amenable to surgical treatment. An adrenal vein sampling should be undertaken for correct lateralization of the source, otherwise a correctable diagnosis may be missed and the incorrect adrenal gland may be removed. Learning points Severe and resistant hypertension can often be associated with underlying PA. ARR is an excellent screening tool in patients with suspected PA. Lateralization with adrenal venous sampling is essential to isolate the source and differentiate between unilateral and bilateral causes of

    Full Text Available Heart failure (HF is a chronic clinical syndrome characterized by the reduction in left ventricular (LV function and it represents one of the most important causes of morbidity and mortality worldwide. Despite considerable advances in pharmacological treatment, HF represents a severe clinical and social burden. Sympathetic outflow, characterized by increased circulating catecholamines (CAs biosynthesis and secretion, is peculiar in HF and sympatholytic treatments (as β-blockers are presently being investigated for the treatment of this disease. Adrenal gland secretes Epinephrine (80% and Norepinephrine (20% in response to acetylcholine stimulation of nicotinic cholinergic receptors on the chromaffin cell membranes. This process is regulated by adrenergic receptors (ARs: α2ARs inhibit CA release through coupling to inhibitory Gi-proteins, and βARs (mainly β2ARs stimulate CA release through coupling to stimulatory Gs-proteins. All ARs are G-protein-coupled receptors (GPCRs and GPCR kinases (GRKs regulate their signaling and function. Adrenal GRK2-mediated α2AR desensitization and downregulation are increased in HF and seem to be a fundamental regulator of CA secretion from the adrenal gland. Consequently, restoration of adrenal a2AR signaling through the inhibition of GRK2 is a fascinating sympatholytic therapeutic strategy for chronic HF. This strategy could have several significant advantages over existing HF pharmacotherapies (antiadrenergic, such as bAR-blockers minimizing side-effects on extra-cardiac tissues and reducing the chronic activation of the renin–angiotensin–aldosterone and endothelin systems.The role of adrenal ARs in regulation of sympathetic hyperactivity opens interesting perspectives in understanding pathophysiology of HF and identifying new potential therapeutic targets.

    The aim of the present study is to determine imaging criteria for differentiating tuberculosis from primary tumors in the adrenal gland on contrast-enhanced CT. Non-contrast and contrast-enhanced CT features in 108 patients with adrenal tuberculosis (n=34) and primary tumor (n=74) were retrospectively assessed for the location, size, calcification and enhancement patterns. The primary tumors included 41 adenomas, 11 pheochromocytomas, 4 carcinomas, 3 lymphomas, 6 myelolipomas, 6 ganglioneuromas, 2 neurilemmomas and 1 ganglioneuroblastoma. Biochemical investigation was performed for all patients. Of the tuberculosis cases, 31 (91%) invaded with bilateral involvement, while 7 (9%) of the primary tumors invaded with bilateral involvement (P<0.001). Tuberculosis often showed calcification (20 of 34; 59%), whereas primary tumors infrequently showed calcification (6 of 74; 8%; P<0.001). Low attenuation in the center with peripheral rim enhancement was more commonly seen in tuberculosis (16 of 34; 47%) than in primary tumors (7 of 74; 9%; P<0.001). In the determination of tuberculosis, the highest sensitivity (91%) and accuracy (91%) were obtained with bilateral involvement, and the highest specificity (99%) was obtained with the contour preserved. In the determination of primary tumors using a combination of having unilateral involvement and being mass-like, the outcome was a sensitivity of 91%, specificity of 94% and accuracy of 92%. CT findings can differentiate tuberculosis from a primary tumor of the adrenal glands with high sensitivity and an acceptable specificity when combined with the endocrinological examination. (orig.)

    We evaluated the diagnostic accuracy of the contrast-enhanced ultrasonography (CEUS), using a second-generation microbubble contrast agent, in differentiating the different types of adrenal mass lesions in 24 dogs. At B-mode ultrasound, 9 lesions involved the right adrenal gland, 14 the left, and 1 was bilateral. Each dog received a bolus of the contrast agent into the cephalic vein, immediately followed by a 5-mL saline flush. The first contrast enhancement of each adrenal lesion was evaluated qualitatively to assess the degree of enhancement and its distribution during the wash-in and wash-out phases, as well as the presence of non-vascularized areas and specific vascular patterns. Pathological diagnoses were determined in all dogs by histopathology or by cytology. Combining enhancement degree and vascularity resulted in the best predictive model, allowing CEUS to differentiate adrenocortical adenoma (n=10), adenocarcinoma (n=7), and pheochromocytoma (n=7) with an accuracy of 91.7% (P adrenal lesions with a sensitivity of 100.0%, a specificity of 80.0%, and an accuracy of 91.7% (P adrenal tumors in dogs.

  9. Functional paraganglioma extra-adrenal

    International Nuclear Information System (INIS)

    Functioning paragangliomas are rare tumours that produce catecholamines.They originate from extra-adrenal chromaffin cells. They are frequently malignant and are associated with high incidence of persistent or recurrent disease after their primary treatment. They are known as glomus, chemodectomas, chromaffin paragangliomas and glomerulocytomas. The location is diverse and reflects the paragangliomar distribution in the body from the base of the skull to the pelvic floor. The paragangliomas are found where there are nodes of the autonomous system, however, approximately 90% of these tumours appear in the adrenal glands (and they constitute the pheochromocytomas) and the remaining 10% is a location extra adrenal, but it has been said that its impact can be underestimated, ranging from 18% to 22% in adults and children up to 30%. The extra-adrenal are originated more frequently in the abdomen (85%), other in the chest (12%) and more rarely in the head and neck (3%). Imaging studies and measurement of non-physiological production of catecholamines may aid in the diagnosis of this entity. Surgery is the treatment of choice. It is presented the case of a primigravidas patient aged 32 with HTAIE requiring caesarean section, who had a postpartum torpid and despite to multiple antihypertensive treatments their pathology was difficult to deal, with ophthalmic complications. Some time later, the patient is studied by hyperhidrosis, laboratory tests and images are requested and it is documented incidentally, a left retroperitoneal tumour, the studies are expanded and reach the correct diagnosis. The tumour required surgical resection. The patient had a satisfactory postoperative period and she discharged with control in the external consultation. (author)

    Full Text Available INTRODUCTION: Congenital adrenal hyperplasia (CAH is an autosomal recessive disease whose main cause is the deficiency of 21-hydroxylase, an enzyme involved in the synthesis of cortisol and aldosterone. There are two forms of CAH, a classical and nonclassical form, being the first objective of analysis in the clinical case. Its clinical manifestations vary in severity, depending on the level of hormone deficiency. Within the classic is described the salt-wasting form, whose consequences are androgen excess and insufficiency of cortisol and mineralocorticoids. So this may manifest as a sex differentiation disorder (virilization of the external genitalia if the fetus is female and adrenal insufficiency. For diagnosis are considered the family history, clinical manifestations, measuring 17-hydroxyprogesterone levels and detection of genetic alteration. CASE REPORT: Patient with a family history of a brother with HSC brother, born with a disorder of sexual differentiation and is discharged with legal male sex. After three months develops adrenal insufficiency and was diagnosed with classical HSC salt-wasting form and determined female karyotype. DISCUSSION: The Pillars of the HSC are handling genetic counseling in families at risk, prenatal treatment with dexamethasone, postnatal glucocorticoid therapy and surgical treatment of disorders of the external genitalia, along with new research based therapy gene and the use of stem cells, requiring this way an integral view of HSC.

    Full Text Available Visceral schwannomas are extremely rare and are usually discov-ered incidentally on USG/CT-Scan. Primary schwannomas of the adrenal gland are extremely uncommon. It has been theorized that they originate from Schwann cells that insulate the nerve fi-bers innervating the adrenal medulla. Histopathological examina-tion coupled with immunohistochemistry provides the definitive diagnosis. A 55 year old normotensive female presented with pain in the right loin since 5 months. Her renal parameters were normal. Contrast enhanced computed tomography of abdomen showed a well delineated 6.5 x 5cms mass at upper pole of her right kidney. 24-hour urinary metanephrine was slightly elevated (3.07mg/24hrs. A decline in Serum cortisol levels was observed following a dexamethasone suppression test (18.89nmol/l. Histopathological examination revealed a spindle cell tumor. Immunohistochemistry showed strong and diffuse positive staining for S-100 with negative expression for CD-117, desmin, CD-34, HMB-45, synaptophysin, chromogranin, cytokeratin, and SMA. Ki-67 index was 2%.A diagnosis of cellular schwannoma of adrenal gland was confirmed.

    The coincidence of a gastrointestinal stromal tumor (GIST) and a neuroendocrine tumor (NET) in neurofibromatosis type 1 (NF1) is described only five times within the literature. We report on a 63 year old Caucasian female with the rare condition of neurofibromatosis type 1 coinciding with recurrent gastrointestinal stromal tumor plus bilateral pheochromocytoma (PCC). After a history of palpitations and dizziness that lasted for years, a left adrenal mass was detected by CT. Laparotomy revealed a pheochromocytoma of the left adrenal gland while an ileoterminal GIST was found incidentally intraoperatively.After six months contralateral PCC and multiple recurrent GIST were resected again. After four years the patient is doing well without any signs of further recurrent tumors.Discussion includes review of the literature.

    The demonstrate the utility of ultrasound (US) in the initial assessment and follow-up of newborns with adrenal masses. A series of 21 newborns presenting adrenal mass studied on the basis of US findings, clinical assessment and biochemical data. Seven patients had congenital neuroblastoma, two had a benign tumor and twelve presented adrenal hemorrhage. Postnatal US study of the course of these patients is essential for the differential diagnosis of their lesions when not diagnosed prenatally. (Author) 20 refs

  18. Synchronous Bilateral Solid Papillary Carcinomas of the Breast

    2013-01-01

    Full Text Available We herein report a case of synchronous bilateral solid papillary carcinoma of the breast. A 73-year-old female had a mass that was detected in the right breast on mammography. An ultrasound examination revealed one intracystic tumor in the right breast and two tumors in the left breast. A fine-needle aspiration biopsy of these three tumors was performed, which revealed a diagnosis of malignancy. A magnetic resonance imaging examination of the breasts showed diffuse small nodules surrounding these tumors bilaterally. Bilateral partial mastectomy and a sentinel lymph node biopsy were performed. Lymph node metastasis was detected in the right axilla, and additional lymph node dissection was performed. The pathological diagnosis was synchronous bilateral breast cancer, invasive ductal carcinoma NOS of the right breast, mucinous carcinomas of the left breast, and bilateral SPCs. A wide range of surgical margins were positive for SPCs, and additional bilateral total mastectomy was then performed. To the best of our knowledge, little is known about synchronous bilateral SPCs. Our case indicates that some SPCs can be widely scattered and make up a variety of invasive carcinomas. It is difficult to make a correct preoperative evaluation in such cases.

  19. Imaging spectrum of adrenal pseudocysts on CT

    International Nuclear Information System (INIS)

    The aim of this study was to analyze the imaging spectrum of adrenal pseudocysts on CT. The CT images of seven patients with pathologic diagnosis of adrenal pseudocysts in our hospital were reviewed for the size, cystic part, solid part, septum, calcification, acute hematoma, and layering appearance. The presence or absence of contrast enhancement of solid parts in each lesion was also assessed if possible. Of the seven adrenal pseudocysts, there were three pure cystic, three mixed cystic and solid, and one solid lesions on CT. Two of the three cystic pseudocysts were septated with calcifications. Layering appearance was present in two mixed lesions. There were central calcifications and acute hematomas in one solid mass. In our study, there was no contrast enhancement of the solid parts of adrenal pseudocysts. The CT appearances of adrenal pseudocysts may range from cystic, mixed, to solid masses. The presence of solid parts of adrenal pseudocysts on CT mimics those of adrenal neoplasms; however, no contrast enhancement of the solid part in the lesion may help in the diagnosis of adrenal pseudocysts and their differentiation from adrenal neoplasms.

  2. Role of the nervous system in cancer metastasis.

    Li, Sha; Sun, Yanlai; Gao, Dongwei

    2013-04-01

    The notion that tumors lack innervation was proposed several years ago. However, nerve fibers are irregulatedly found in some tumor tissues. Their terminals interaction with cancer cells are considered to be neuro-neoplastic synapses. Moreover, neural-related factors, which are important players in the development and activity of the nervous system, have been found in cancer cells. Thus, they establish a direct connection between the nervous system and tumor cells. They modulate the process of metastasis, including degradation of base membranes, cancer cell invasion, migration, extravasation and colonization. Peripheral nerve invasion provides another pathway for the spread of cancer cells when blood and lymphatic metastases are absent, which is based on the interactions between the microenvironments of nerve fibers and tumor cells. The nervous system also modulates angiogenesis, the tumor microenvironment, bone marrow, immune functions and inflammatory pathways to influence metastases. Denervation of the tumor has been reported to enhance cancer metastasis. Stress, social isolation and other emotional factors may increase distant metastasis through releasing hormones from the brain, the hypothalamic-pituitary-adrenal axis and autonomic nervous system. Disruption of circadian rhythms will also promote cancer metastasis through direct and indirect actions of the nervous system. Therefore, the nervous system plays an important role in cancer metastasis. PMID:23599747

  4. Differential diagnosis in the sonographic evaluation of adrenal metastases

    International Nuclear Information System (INIS)

    The sonographic detection of adrenal masses in patients with neoplasms, especially neoplasms of the lung, can be related to the presence of both metastases and adenomas. In order to assess the benign/malignant nature of the such lesions, the adrenal glands of 43 patients with neoplasms (36 of them lung cancers) were studied with sonography (US) and fine needle aspiration biopsy (FNAB): in all, 58 masses were seen (28 monolateral and 15 bilateral). Six lesions (13%) presented with cytological features of benignancy, and on US they appeared as hypoechoic (as compared to the liver), round masses, with regular margins, ranging in size from 1.2 cm to 3.4 cm (average: 2.6 cm). In the remaining 34 patients (80%), cellular material with features of malignancy was obtained with FNAB. The US appearence of these metastases was heterogenous, with the same echogenicity as the liver, and average size >3 cm. On the basis of data obtained, the limit of 3 cm (if we consider the average dimension), corresponds to the threshold of benignancy, as well as the monolateral and hypoechoic appearence of the lesion. To sum up, the use of FNAB should be limited to those lesions which present with typical adenomatous features and for borderline lesions, while the diagnosis of metastases is sufficiently accurate (p3 cm

    2013-11-01

    Full Text Available Adrenal incidentalomas are masses of the adrenal gland discovered inadvertently during diagnostic procedures, from which a significant percentage are pheochromocytomas and these tumors are rare. Here we report a case of a 15-year-old male dog whose main complaints were a soft cervical mass and mild generalized weakness. Blood cell count, routine biochemistry, arterial blood pressure and electrocardiogram were performed. Diagnostic imaging revealed a 3.5 cm mass next to the right adrenal gland. Surgery was performed and histopathology examination of the mass confirmed a malignant pheochromocytoma. The dog died 96 hours later after surgery. At necropsy, metastasis was found in cervical lymph node. Considering vague and episodic clinical signs, pheochromocytoma antemortem diagnosis is uncommon. The main aim of this case is to highlight this endocrinology disorder, increasing the awareness of clinicians to this difficult diagnostic condition.

  8. Computed tomographic features of the adrenal glands

    International Nuclear Information System (INIS)

    Conventional radiography of the adrenal glands are too often unsatisfactory. It is well known that the whole body computed tomography is very useful in identifying retroperitoneal pathology. The authors intended to present normal data of adrenal glands for preparation of basis for interpretation of abnormalities. We reviewed CT scans of 30 cases without evidence of adrenal disease and 4 cases of adrenal lesions. The results are as follows: 1. There were 16 male and 14 female patients, and their ages ranged from 10 to 70 years. 2. On CT, both glands were shown in 23 (76%), the right in 24 (80%) and the left in 26 (86%). 3. Most of the right adrenal gland was linear or comet in shape in the apex, and partly 'inverted V' in the base. 4. The right adrenal had length of 2.4 ± 0.8 cm, width of 2.6 ± 0.8 cm and thickness of 0.6 ± 0.1 cm. The left adrenal, 2.5 ± 0.7 cm, 2.4 ± 0.5 cm and 0.7 ± 0.1 cm respectively. 5. In 2 cases of Cushing's syndrome, CT demonstrated grossly enlarged, smooth-contoured adrenal glands with convex borders. 6. In the case of cortical adenoma, CT showed the mass of homogeneous low density as a result to high total fat content.7. In pheochromocytoma, CT showed relatively large mass with low density.

    1997-11-01

    We reported a 67-year-old woman with bilateral caudate head infarcts. She developed sudden mutism followed by abulia. She was admitted to our hospital 2 months after ictus for further examination. She showed prominent abulia and was inactive, slow and apathetic. Spontaneous activity and speech, immediate response to queries, spontaneous word recall and attention and persistence to complex programs were disturbed. Apparent motor disturbance, gait disturbance, motor aphasia, apraxia and remote memory disturbance were not identified. She seemed to be depressed but not sad. Brain CT and MRI revealed bilateral caudate head hemorrhagic infarcts including bilateral anterior internal capsules, in which the left lesion was more extensive than right one and involved the part of the left putamen. These infarct locations were thought to be supplied by the area around the medial striate artery including Heubner's arteries and the A1 perforator. Digital subtraction angiography showed asymptomatic right internal carotid artery occlusion. She bad had hypertension, diabetes mellitus and atrial fibrillation and also had a left atrium with a large diameter. The infarcts were thought to be caused by cardioembolic occlusion to the distal portion of the left internal carotid artery. Although some variations of vasculature at the anterior communicating artery might contribute to bilateral medial striate artery infarcts, we could not demonstrate such abnormalities by angiography. Bilateral caudate head infarcts involving the anterior internal capsule may cause prominent abulia. The patient did not improve by drug and rehabilitation therapy and died suddenly a year after discharge. PMID:9503974

    A clinical feature of bilateral popliteal arterial dissection without involving the descending aorta, bilateral iliac, as well as femoral arteries has never been reported in the past literature. We report a 56-year-old man with hypertension and coronary artery disease who presented to our emergency department with complaints of bilateral knee pain after long-distance walking. Physical examination was notable for elevated blood pressure, but there was no palpable pulsation over dorsalis pedis arteries on his feet. Laboratory evaluation revealed a d-dimer level of 35.2 mg/L (FEU) on the day of the test and 1.2 mg/L one and a half months ago (normal level, <0.55). These findings were suggestive of a recent-onset peripheral arterial occlusive disorder. Computed tomography of the aorta showed bilateral popliteal arterial dissection with arterial intimal flap. Abdominal aorta, bilateral iliac, and femoral arteries remained intact with only arteriosclerotic change. Minimally invasive endovascular stent grafting was then performed. The patient had an uneventful recovery. PMID:21106320

    Full Text Available Laparoscopic adrenalectomy is the standard of care for management of adrenal neoplasms. However, large sized adrenal lesions are considered as relative contraindication for laparoscopic extirpation. We report laparoscopic excision of giant ganglioneuroma of adrenal gland in a 33-year-old female patient. Patient was presented with left loin pain of 2 months duration. Computed tomography (CT scan was suggestive of non-enhancing left suprarenal mass measuring 17 × 10 cm. Preoperative endocrine evaluation ruled out functional adrenal tumor. Patient underwent transperitoneal excision of suprarenal mass. The lesion could be completely extirpated laparoscopically. Duration of surgery was 250 minutes. Estimated blood loss was 230 milliliters. Specimen was extracted through pfannenstiel incision. No significant intraoperative or postoperative happenings were recorded. Microscopic features were suggestive of ganglioneuroma of adrenal gland.

  14. Ultrasonographic diagnosis of the adrenal lesion

    International Nuclear Information System (INIS)

    To evaluate the accuracy and efficacy of ultrasonography for diagnosis of the adrenal mass, sonographic results of the 45 patients who underwent computed tomography and ultrasonography were analysed. Sixteen patients of them were verified at operation and the remainder was finally diagnosed by clinical and endocrinological examination. Overall diagnostic accuracy, sensitivity, specificity, positive predictive value and negative predictive value of ultrasonography in the adrenal disease are 84%, 81%, 100%, 100% and 53%, respectively. Of the seven negative diagnosis, six cases were small mass(under 2cm)and five cases were located in the left adrenal gland. Ultrasonography is efficient as a primary diagnostic method in detecting the adrenal mass. but small mass less than 2 cm, especially in the left adrenal gland is difficult to diagnose by ultrasonography

    Full Text Available Context: The adrenal gland is a common site for neoplastic diseases and primary adrenal lymphoma (PAL is a rare tumor with around 120 cases reported so far. Case Report: We present a rare case of 76-year-old male who presented with headache, confusion, inappropriate body movements and abdominal pain. Adrenal biopsy revealed PAL and he has had an excellent neurologic outcome to date with chemotherapy and involved field radiation. Conclusion: The majority of cases of PAL are B cell lymphomas with diffuse large cell in 70% of cases. Clinical symptoms are variable and patients may present with abdominal pain, fever, anorexia, weight loss, fatigue or symptoms of adrenal insufficiency. Therapeutic modalities for PAL include surgery, chemotherapy and radiotherapy and corticosteroid replacement. With this case report, we hope to raise awareness about this rare disease and to include lymphoma in the differential of adrenal masses.

    2013-06-01

    Full Text Available Morgagni hernia is a rare congenital diaphragmatic hernia. It is seen rarely bilaterally. Patients are usually asymptomatic. Therefore, diagnosis may be delayed until adulthood. Significant morbidity can occur in case complications arise and diagnosis is delayed. The patient, a 74 year-old female, presented in this article, was admitted to the emergency department with abdominal pain, vomiting, and shortness of breath. The plain abdominal radiograph of the patient revealed bowel obstruction and suspicious appearence in favor of the diaphragmatic hernia on both sides of the sternum. Computed tomography revealed bilaterally incarcerated Morgagni hernia with strangulated omentum in the right side of the sternum and a part of colon in the left side of sternum. Incarcerated organs were withdrawn to peritoneal cavity and defects of hernia were sutured primarily on laparatomy. Because bilateral incarcerated Morgagni hernia can be seen rarely, this case was reported.

    Breast cancer currently affects 1 in 8 women in the UK during their lifetime. Common sites for breast cancer metastasis include the axillary lymph nodes, bones, lung, liver, brain, soft tissue and adrenal glands. There is well documented evidence detailing breast metastasis to the gastrointestinal tract but anal metastasis is exceptionally rare. We present the case of a 78-year-old woman with an anal metastasis as the sentinel and isolated presentation of an invasive ductal breast carcinoma. As advances in the treatment of breast cancer improve, and with an ageing and expanding population, there will be an increasing number of cancer survivors, and more of these unusual presentations may be encountered in the future.

    2012-01-01

    Full Text Available Hepatocellular carcinoma ranks 5th in prevalence and 3rd in cancer mortality worldwide. The prognosis of this disease is very poor: the 5-year survival rate was not more than 3–5%. Metastases generally occur in the lung, in the lymph nodes of the abdomen, chest, and neck, in the vertebrae, kidneys, and adrenals. The cases of brain metastasis from hepatocellular cancer are very rare. Overall, the prognosis is very poor for patients with brain metastases from hepatocellular carcinoma. Nevertheless, solitary brain metastases and good hepatic function are favorable survival criteria; thus, the treatment of this group of patients may lead to their better survival. The paper describes a clinical case of brain metastasis from hepatocellular carcinoma in a patient receiving the combination treatment involving neurosurgical treatment and targeted therapy.

    Unilateral pallidotomy is a safe and effective treatment for medically refractory bradykinetic Parkinson's disease, especially in those patients with levodopa-induced dyskinesia and severe on-off fluctuations. The efficacy of bilateral pallidotomy is less certain. The authors completed 11 of 12 attempted bilateral pallidotomies among 150 patients undergoing pallidotomy at New York University. In all but one patient, the pallidotomies were separated by at least 9 months. Patients were selected for bilateral pallidotomy if they exhibited bilateral rigidity, bradykinesia, or levodopa-induced dyskinesia prior to treatment or if they exhibited disease progression contralateral to their previously treated side. The Unified Parkinson's Disease Rating Scale (UPDRS) and timed upper-extremity tasks of the Core Assessment Protocol for Intracerebral Transplantation (CAPIT) were administered to all 12 patients in the "off" state (12 hours without receiving medications) preoperatively and again at 6 and 12 months after each procedure. The median UPDRS and contralateral CAPIT scores improved 60% following the initial procedure (p = 0.008, Wilcoxon rank sums test). The second pallidotomy generated only an additional 10% improvement in the UPDRS and CAPIT scores ipsilateral to the original procedure (p = 0.05). Worsened speech was observed in two cases. In the 12th case, total speech arrest was noted during test stimulation. Speech returned within minutes after stimulation was halted. Lesioning was not performed. These results indicate that bilateral pallidotomy has a narrow therapeutic window. Motor improvement ipsilateral to the first lesion leaves little room for further improvement from the second lesion and the risk of speech deficit is greatly enhanced. Chronic pallidal stimulation contralateral to a previously successful pallidotomy may prove to be a safer alternative for the subset of patients who require bilateral procedures. PMID:15096015

    2009-10-01

    Paragangliomas of the head and neck are rare neoplasms presented as cervical mass, generally bilateral, that arise from chemoreceptors located at the carotid bifurcation (carotid body tumors), along the vagus nerve (vagal paragangliomas), and in the jugular fossa and tympanic cavity (jugulotympanic paragangliomas). They are typically asymptomatic at the beginning, highly vascular, slow-growing and compressing the surrounding anatomic structures. Only radical surgery is the curative treatment for paragangliomas. We present a case of a 62- year-old woman with a diagnosis of bilateral neck paragangliomas where surgical removal was judged burdened by excessive risk because of the size of the tumor.

    A patient with bilateral adrenal hyperplasia, due to the ectopic adrenocorticotrophic hormone (ACTH) syndrome, received a 3-month course of treatment with 1,1 dichloro-2(o-chlorophenyl)-2-(p-chlorophenyl)ethane (o,p' DDD), which caused adrenal hypofunction requiring steroid therapy. Eleven months later, Cushing's syndrome recurred. His CT scan showed a left adrenal gland that was enlarged and a normal-sized right adrenal gland. However, the NP-59 image showed increased uptake by both glands. Venous effluent was sampled from each adrenal vein. The plasma cortisol level from the left gland was 1392 ng/ml, and that from the right gland was 667 ng/ml. The latter value was not significantly different from the values obtained at peripheral sites (517-744 ng/ml). In the course of recovery from o,p' DDD damage, the ability of the adrenal gland to take up NP-59 may be restored before the return of its biosynthetic and secretory functions. Serial NP-59 adrenal images can anticipate the recurrence of Cushing's syndrome after adrenolytic therapy, thereby permitting early retreatment

  11. Adrenal incidentaloma and the Janus Kinase 2 V617F mutation: A case-based review of the literature

    2013-01-01

    Full Text Available Adrenal incidentaloma was detected in an 81-year-old male patient and a 37-year-old female patient who had been diagnosed with essential thrombocytosis. Each patient′s Janus Kinase 2 (JAK2 V617F mutation was positive, and they were evaluated as having non-functional adrenal incidentaloma. The JAK2 activates the signal transducers and activators of transcription (STAT proteins which then activate the phosphoinositol-3 kinases, Ras, mitogen-activated protein (MAP kinases, and transcription. Constitutive activation causes cell proliferation and dysregulation of apoptosis. It is thought that STAT3 activation-mediated JAK family kinases have a central role in the solid tumor cell series. Permanent activation of STAT3 and STAT5 causes tumor cell proliferation, survival, metastasis, and an increase in tumor-mediated inflammation in solid and hematologic tumors. According to our literature screening, irregular JAK signaling, seen at the pathogenesis of many solid and hematologic tumors, has not been previously evaluated with regard to adrenal tumors. As a result, our cases are the first coexistence of JAK V617F mutation with adrenal incidentaloma in the literature. Because of this, we think that JAK2 mutation must be evaluated to clarify the etiology of adrenal incidentalomas.

  12. Adrenal scanning with 131I-19-cholesterol

    International Nuclear Information System (INIS)

    The purpose of this paper is to describe our clinical experience of adrenal scanning with 131I-19-cholesterol and discuss its clinical usefulness. Adrenal scanning was performed for 21 patients with hypertension. One millicurie of 131I-19-cholesterol was injected intravenously and adrenal scannings were taken 6 to 11 days after injection with a rectilinear scanner or a gamma camera. No patient had an untoward reaction to the radiopharmaceutical. Confirmed diagnosis was obtained in 7 of 21 patients, i.e., 3 cases of primary aldosteronism, 1 idiopathic aldosteronism, 1 Cushing's syndrome and 2 cases of the essential hypertension. Among all of the primary aldosteronism and Cushing's syndrome, adrenal scanning gave clear evidence of concentration of radioactivity at the site of tumor. In the idiopathic aldosteronism of our study, uptake of radioactivity was brightly visible on the right, while uptake by the left gland was inhibited, so this case was diagnosed incorrectly as primary aldosteronism. The kidney scan with 203Hg-chlormerodrin obtained without moving the patient after an adrenal scan was very useful for getting information of anatomical site of the activity. The effective half-life was calculated as 1.83 days by means of sequential profile whole-body scannings, and the total-body absorbed radiation dose was estimated as 0.65 rad/mCi by using MIRD pamphlets. Our conclusion is that the adrenal scanning with 131I-19-cholesterol is very useful for localization of the functional adrenal cortical tumor. (author)

  13. Therapy of adrenal insufficiency: an update.

    Science.gov (United States)

    Falorni, Alberto; Minarelli, Viviana; Morelli, Silvia

    2013-06-01

    Adrenal insufficiency may be caused by the destruction or altered function of the adrenal gland with a primary deficit in cortisol secretion (primary adrenal insufficiency) or by hypothalamic-pituitary pathologies determining a deficit of ACTH (secondary adrenal insufficiency). The clinical picture is determined by the glucocorticoid deficit, which may in some conditions be accompanied by a deficit of mineralcorticoids and adrenal androgens. The substitutive treatment is aimed at reducing the signs and symptoms of the disease as well as at preventing the development of an addisonian crisis, a clinical emergency characterized by hypovolemic shock. The oral substitutive treatment should attempt at mimicking the normal circadian profile of cortisol secretion, by using the lower possible doses able to guarantee an adequate quality of life to patients. The currently available hydrocortisone or cortisone acetate preparations do not allow an accurate reproduction of the physiological secretion pattern of cortisol. A novel dual-release formulation of hydrocortisone, recently approved by EMEA, represents an advancement in the optimization of the clinical management of patients with adrenal insufficiency. Future clinical trials of immunomodulation or immunoprevention will test the possibility to delay (or prevent) the autoimmune destruction of the adrenal gland in autoimmune Addison's disease.

  14. Magnetic resonance imaging of the adrenal lesions

    International Nuclear Information System (INIS)

    Magnetic resonance imaging (MRI) was performed in 18 patients with adrenal masses using a superconducting magnet operating at 1.5 Tesla. Seven pheochromocytomas, five aldosterone-producing adenomas, two hydrocortisone-producing adenomas, two adrenal metastases, one adrenal carcinoma and one adrenal myelolipoma were examined by this method. Spin-echo pulse sequences were obtained at the repetition time (TR) 0.1 ∼ 1.6 sec and the echo time (TE) 14 ∼ 75 msec. T1-weighted images of phechromocytomas were similar in signal intensity to the kidney, while T2-weighted images revealed much higher intensity than those of the liver and kidney. The signal intensity on T1-and T2-weighted images of adrenal adenomas were similar, irrespective of endocrine characteristics, to that of the liver and kidney. T1-weighted images which detect small masses more than 1 cm in diameter offer anatomic resolution similar to computed tomography (CT) and T2-weighted images give information about internal characteristic of adrenal masses. It is expected that MRI is more useful in diagnosis of adrenal masses than CT. (author)

  15. Normal dexamethasone-suppression adrenal scintiscan

    International Nuclear Information System (INIS)

    To establish the parameters of adrenal imaging under dexamethasone suppression (DS), 18 normotensive, normal male volunteers underwent dexamethasone-suppression adrenal scintiscanning. Five control groups were established and given dexamethasone, either 8 mg for 2 days or 4 mg for 7 days before 6β-[1311]iodomethyl-norcholesterol (NP-59) administration. NP-59 was given in doses of 2, 1, or 0.5 mCi. Early visualization (3-5 days) of the adrenals was noted in the groups on the 8 mg DS regimen with either 1 or 2 mCi of NP-59. Late visualization (5-7 days) was noted in the groups that received 4 mg DS and either 2, 1, or 0.5 mCi of MP-59, respectively. The normal adrenal will demonstrate uptake of NP-59 under DS, and the duration of DS before imaging is the critical factor as to when discernible adrenal visualization will occur. The documentation of the normal suppression interval on these DS regimens provides a basis for the correct diagnostic interpretation of adrenal hyperfunction as seen on the dexamethasone-suppression NP-59 adrenal scan

    Therapeutic options available for the treatment of Cushing's syndrome (CS) have expanded over the last 5 years. For instance, the efficient management of severe hypercortisolism using a combination of fast-acting steroidogenesis inhibitors has been reported. Recent publications on the long-term efficacy of drugs or radiation techniques have also demonstrated low toxicity. These data should encourage endocrinologists to reconsider the place of bilateral adrenalectomy in patients with ACTH-dependent aetiologies of CS; similarly, the indication of bilateral adrenalectomy is reassessed in primary bilateral macronodular adrenal hyperplasia. The objective of this review is to compare the efficacy and side effects of the various therapeutic options of hypercortisolism with those of bilateral adrenalectomy, in order to better define its indications in the 21st century.

  17. CT-guided biopsy of adrenal masses in preoperative management of bronchogenic carcinoma

    International Nuclear Information System (INIS)

    Discovery of an adrenal mass in a patient with a bronchogenic carcinoma requires assessment of the histological type in order to choose the best treatment. Over the past 6 years unilateral (n = 23) or bilateral (n = 6) adrenal masses were discovered using computed tomography (CT) in 29 patients during staging of bronchogenic carcinoma. CT-guided biopsy was performed in all cases and diagnosed metastases in 14 patients and benign adenomas in 12, as well as 3 false-negative results (89% accuracy). Minor complications occurred in 3 cases. Metastases were more frequent from adenocarcinoma (10 of 11) than from squamous-cell carcinoma (4 of 12) and undifferential carcinoma (3 of 6). CT-guided biopsy is a fairly reliable method to distinguish metastases from benign adenomas. (orig.)

    Primary urethral carcinoma is extremely rare, accounting for less than 1% of all female genitourinary tract cancers. To the best of our knowledge, this patient is the first reported case of primary urethral carcinoma presenting metastasis to eyes. The diagnosis of metastasis involving the choroids should be suspected in patient with history of carcinoma and a decreased visual acuity or any other visual symptom. Case presentation: A 43-year-old woman underwent a total hysterectomy, cystectomy and bilateral pelvic lymphadenectomy due a primary adenocarcinoma of the proximal urethra. Adjuvant pelvic radiotherapy and six cycles of chemotherapy using cisplatin were performed. The patient made follow-up with no evidence of oncologic disease. However, nine months later, the patient reported visual alterations. Ophthalmoloscopic examination showed choroid lesions in both eyes that were compatible with metastatic choroids tumor and nuclear magnetic resonance suggested bilateral retinal metastasis and left meningioma parasagittal in parietal region. She was undergoing a new palliative chemotherapy, but the disease developed and there were metastasis to bone four months later. The patient died fourteen months after the surgery. (author)

  20. Adrenal pathology in childhood: a spectrum of disease

    International Nuclear Information System (INIS)

    Adrenal lesions in children may present with an asymptomatic adrenal mass lesion, an endocrinopathy, a hypertensive or metabolic crisis or a paraneoplastic syndrome. Some of the underlying disease processes remain localised within the adrenal gland or may develop into disseminated disease. The role of the radiologist is to confirm the adrenal location of a lesion and to document any other foci of disease. Ultrasound, CT, MR imaging and metaiodobenzylguanidine scintigraphy are the most commonly utilised imaging modalities for examining the adrenal glands and their pathologies in children. This paper reviews the spectrum of adrenal disease in childhood and presents the information as a series of radiological appearances: anomalies of adrenal shape, location, number and size, cystic adrenal masses, solid adrenal mass lesions, and adrenal calcifications are all examined. The radiological findings must always be interpreted in conjunction with the patient's age, the clinical history, the findings on physical examination and the available biochemical data. (orig.)

    Imaging diagnosis of adrenal tumors is increasingly frequent. Characterization and differentiation of benign adenomas and malignant injures is very important, mainly in the patient with malignant or functioning disease. Computed tomography, magnetic resonance imaging and positron emission tomography/computed tomography allowed greater precision in characterizing and differentiating the adrenal masses in a non-invasive way. This review explained the physiological principles supporting these techniques, its advantages and restrictions. The main characteristics of the most frequent adrenal tumor images were described, in addition to submitting an algorithm for the use of these diagnostic means

    Full Text Available Adrenal histoplasmosis is an uncommon cause for adrenal insufficiency. The duration of treatment for adrenal histoplasmosis is not clear. Existing treatment regimens advocate antifungals given for periods ranging from 6 months to 2 years. We report here a rare case who showed persistence of histoplasma in adrenal biopsy 7 years after being initially treated with itraconazole for 9 months. This calls for a prolonged therapy with regular review of adrenal morphology and histology in these patients.

  6. Management ovarian brain metastasis

    International Nuclear Information System (INIS)

    Ovarian cancer is the cause of the most frequent mortality and morbidity from gynaecologist malignant diseases. Nowadays, the standard treatment is the optimal debulkization with the following platinum chemotherapy at all the histological subtypes. Even despite the progress in the surgery and chemotherapy, in the last years 5-year-survival at the patients with initially progressive disease has remained relatively low. One of the least favourable situations is the presence of brain metastasis where the survival is limited only to a few weekends. The brain metastases are not very common at ovarian cancer even despite the fact that in the last years there has been in decrease. Brain metastases typically occur metachromically. Our patient had metachromic metastasis in the brain without the presence of extra cranial disease. Radiotherapy in the area of brain metastasis in a monotherapy was secure and well tolerated at the relatively good efficiency. (author)

    As one kind of infectious diseases of adrenal gland, adrenal tuberculosis can result in a life-threatening disorder which is called primary adrenal insufficiency(PAI) due to the destruction of adrenal cortex. Computed tomography(CT) and magnetic resonance imaging(MRI) play significant roles in the diagnosis of this etiology of PAI based on the CT and MRI appearances of the adrenal lesions. In this mini-review, we intend to study the CT and MRI features of adrenal tuberculosis, which could be helpful to both endocrinologist and radiologist to establish a definitive diagnosis for adrenal tuberculosis resulting in PAI.

  9. Role of ACTH in the Interactive/Paracrine Regulation of Adrenal Steroid Secretion in Physiological and Pathophysiological Conditions.

    Science.gov (United States)

    Lefebvre, Hervé; Thomas, Michaël; Duparc, Céline; Bertherat, Jérôme; Louiset, Estelle

    2016-01-01

    In the normal human adrenal gland, steroid secretion is regulated by a complex network of autocrine/paracrine interactions involving bioactive signals released by endothelial cells, nerve terminals, chromaffin cells, immunocompetent cells, and adrenocortical cells themselves. ACTH can be locally produced by medullary chromaffin cells and is, therefore, a major mediator of the corticomedullary functional interplay. Plasma ACTH also triggers the release of angiogenic and vasoactive agents from adrenocortical cells and adrenal mast cells and, thus, indirectly regulates steroid production through modulation of the adrenal blood flow. Adrenocortical neoplasms associated with steroid hypersecretion exhibit molecular and cellular defects that tend to reinforce the influence of paracrine regulatory loops on corticosteroidogenesis. Especially, ACTH has been found to be abnormally synthesized in bilateral macronodular adrenal hyperplasia responsible for hypercortisolism. In these tissues, ACTH is detected in a subpopulation of adrenocortical cells that express gonadal markers. This observation suggests that ectopic production of ACTH may result from impaired embryogenesis leading to abnormal maturation of the adrenogonadal primordium. Globally, the current literature indicates that ACTH is a major player in the autocrine/paracrine processes occurring in the adrenal gland in both physiological and pathological conditions.

    Purpose: To describe CT morphology of untreated adrenal tuberculosis during the different stages of the natural history of the disease and to evaluate the diagnostic implications of CT features. Materials and methods: We retrospectively evaluated CT features in 42 patients with documented adrenal tuberculosis for the location, size, morphology, and enhancement patterns shown on CT images. The clinical duration were correlated with the CT features. Results: Of the 42 patients with untreated adrenal tuberculosis, bilaterally enlarged adrenal glands were revealed in 38 cases (91%), unilaterally enlarged in 3 cases (7%), and normal size in 1 case (2%). Of the 41 cases (98%) with enlargement, mass-like enlargement was seen in 20 cases (49%) and enlargement with preserved contours in 21 cases (51%). Peripheral rim enhancement presented in 22 cases (52%) on contrast-enhanced CT. Non-enhanced CT scan revealed calcification in 21 cases (50%). As the duration of Addison's disease increased, the presence of calcification and contour preservation increased concomitantly (p < 0.001), whereas peripheral rim enhancement and mass-like enlargement decreased concomitantly on CT images (p < 0.001). Conclusion: CT may be helpful in diagnosing adrenal tuberculosis when clinically suspected, and CT features are correlated to the clinical duration of Addison's disease.

  11. Giant adrenal incidentaloma in young patient

    International Nuclear Information System (INIS)

    Incidental adrenal tumors are lesions occasionally observed during abdominal US or CT scans. These tumors have been observed in patients without clinical or laboratorial signs of adrenal disease. The authors report a case of a 18 - years - old young man who was admitted to the Franco da Rocha Hospital, Sao Paulo, with abdominal pain and a palpated mass in the epigastrium which began one month ago. These findings were preceded by a blunt trauma at the epigastrium three months earlier. First clinical hypothesis was of a traumatic pancreatic pseudocyst. However, investigation and laparotomy showed a large left adrenal solid mass, weighting 700 g. The mass was removed and histology was performed. There was no evidence of malignant neoplasm, then the diagnostic of incidental adenoma of adrenal was confirmed. The authors hope to stimulate surgeons for early detection of these lesions in order to prevent the complications and improve the prognosis. (author)

    Metastasis fingers (acral metastasis) are finding a poor prognosis. Past medical history should be questioned and metastasis from primary tumor should be kept in mind in patients with pain, swelling, and hyperemia in fingers. Successful surgical treatment on acral metastasis does not extend the life expectancy; however, it reduces the patient’s pain during his terminal period, saves the functions of the limb, and increases life comfort.

    Metastasis is responsible for most cancer mortality. The process of metastasis is complex, requiring the coordinated expression and fine regulation of many genes in multiple pathways in both the tumor and host tissues. Identification and characterization of the genetic programs that regulate metastasis is critical to understanding the metastatic process and discovering molecular targets for the prevention and treatment of metastasis. Genomic approaches and functional genomic analyses can syst...

  1. Compressive Bilateral Filtering.

    Sugimoto, Kenjiro; Kamata, Sei-Ichiro

    2015-11-01

    This paper presents an efficient constant-time bilateral filter that produces a near-optimal performance tradeoff between approximate accuracy and computational complexity without any complicated parameter adjustment, called a compressive bilateral filter (CBLF). The constant-time means that the computational complexity is independent of its filter window size. Although many existing constant-time bilateral filters have been proposed step-by-step to pursue a more efficient performance tradeoff, they have less focused on the optimal tradeoff for their own frameworks. It is important to discuss this question, because it can reveal whether or not a constant-time algorithm still has plenty room for improvements of performance tradeoff. This paper tackles the question from a viewpoint of compressibility and highlights the fact that state-of-the-art algorithms have not yet touched the optimal tradeoff. The CBLF achieves a near-optimal performance tradeoff by two key ideas: 1) an approximate Gaussian range kernel through Fourier analysis and 2) a period length optimization. Experiments demonstrate that the CBLF significantly outperforms state-of-the-art algorithms in terms of approximate accuracy, computational complexity, and usability. PMID:26068315

    Full Text Available We report herein a case of idiopathic adrenal hematoma. A 59-year-old Japanese man was referred to our hospital for evaluation of a 7.0 cm mass in the right upper abdominal cavity. The tumor was suspected to originate from either the posterior segment of the liver or the right adrenal gland. His chief complaint was weight loss of 8 kg over the previous 6 months. He had no past medical history and took no medications, including no anticoagulants. Laboratory data were almost normal except for a slight elevation of PIVKA-II. The origin of the tumor was found to be the adrenal gland, as angiography revealed the blood supply to the mass to derive from the right superior and inferior adrenal arteries. A fine needle biopsy of the lesion was unable to confirm the diagnosis. Open right adrenalectomy was performed. The histopathological findings of the surgical specimen revealed a hematoma with normal adrenal tissue. In the absence of any obvious etiology, the diagnosis was idiopathic adrenal hematoma.

    Full Text Available Abstract Background The objective of this study was to identify prognostic factors for survival in patients with primary diffuse large B-cell lymphoma (DLBCL of the adrenal gland. Methods Thirty one patients diagnosed with primary adrenal DLBCL from 14 Korean institutions and treated with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone were analyzed. Results Complete remission (CR and overall response rate after R-CHOP chemotherapy were 54.8% and 87.0%. The 2-year estimates of overall survival (OS and progression-free survival (PFS were 68.3% and 51.1%. In patients achieving CR, significant prolongations of OS (P = 0.029 and PFS (P = 0.005 were observed. Ann Arbor stage had no influence on OS. There was no significant difference in OS between patients with unilateral involvement of adrenal gland and those with bilateral involvement. When staging was modified to include bilateral adrenal involvement as one extranodal site, early stage (I or II significantly correlated with longer OS (P = 0.021 and PFS (P 0.001. Conclusions Contrary to prior reports, our data suggests that outcomes of primary adrenal DLBCL are encouraging using a regimen of R-CHOP, and that achieving CR after R-CHOP is predictive of survival. Likewise, our modified staging system may have prognostic value.

    To reassess the usefulness of {sup 18}F-FDG PET in the differential diagnosis of benign and malignant tumors from adrenal masses detected on CT or MR. A retrospective analysis was performed on 20 patients (n = 21), on whom PET scans were obtained with characteristically benign CT (n = 21) and MR (n = 2) findings. Seventeen patients had a proven primary malignancy and three patients had adrenal incidentalomas. PET findings were interpreted as positive if the {sup 18}F-FDG uptake of the adrenal mass was greater than or equal to that of the liver. Each adrenal mass was characterized by its size and standardized uptake value (SUV). For statistical analysis, the t-test was used to analyze results for size and SUV. PET findings were positive for eight adrenal masses; two masses were pathologically proven as adrenocortical oncocytomas. The false positive rate was 38% in all patients and 41% in patients with a malignancy. {sup 18}F-FDG PET was useful in evaluating the primary lesions as well as metastases, but a high false positive rate in patients with a primary malignancy should be considered in the diagnosis of metastasis to the adrenal gland.

    Dopamine is known to play a role in the modulation of aldosterone and catecholamine secretion from the adrenal gland, where dopamine receptors (DR), in particular the DR type 2 (D(2)), have been found to be expressed. DR expression has also been demonstrated in some types of benign adrenal tumors. The aims of the current study were to evaluate DR expression and D(2) localization in the normal adrenal gland and in different types of benign and malignant adrenal tumors, as well as to evaluate the in vitro effects of the dopamine agonists bromocriptine and cabergoline on hormone secretion in nontumoral adrenal cells. Adrenal tissues from 25 patients, subjected to adrenal surgery for different diseases, were studied. These included three normal adrenals; five adrenal hyperplasias; four aldosterone-secreting, two cortisol-secreting, and two clinically nonfunctioning adrenal adenomas; two aldosterone-secreting, two cortisol-secreting, and two androgen-secreting adrenal carcinomas; and three pheochromocytomas. In all tissues, DR and D(2) isoform (D(2long) and D(2short)) expression was evaluated by RT-PCR. D(2) localization was also evaluated by immunohistochemistry using a specific polyclonal antibody, whereas D(2)-like receptor expression was evaluated by receptor-ligand binding study, using the radiolabeled D(2) analog (125)I-epidepride. The effects of bromocriptine and cabergoline on baseline and ACTH and/or angiotensin II-stimulated aldosterone, cortisol, and androstenedione secretion were evaluated in cell cultures derived from five different adrenal hyperplasia. At RT-PCR, both D(1)-like and D(2)-like receptors were expressed in all normal and hyperplastic adrenals. D(2) and D(4) were expressed in aldosterone- and cortisol-secreting adenomas, cortisol-secreting carcinomas, and clinically nonfunctioning adenomas, whereas no DR was expressed in aldosterone- and androgen-secreting carcinomas. D(2), D(4), and D(5) were expressed in pheochromocytomas. In all D(2

  6. CT of the normal adrenal glands and image diagnosis of the adrenal diseases

    International Nuclear Information System (INIS)

    The appearances of the adrenal glands of 200 normal subjects were evaluated using computed tomography. Comparative assessments were also made of adrenal diseases in 44 patients with using CT, ultrasound, adrenal scintigraphy and angiography. 100%(5/5) of the adenomas in Cushing's Syndrome were detected by CT, scintigraphy and venography; and 60% (3/5) of them, by ultrasonography. All(4/4) adrenal hyperplasias were diagnosed by scintigraphy; and 75% (3/4) of them by C.T. The differential diagnosis of adenomas and hyperplasia in Cushing's Syndrome can be accomplished using scintigraphy and CT. The rates for diagnosing adenomas and hyperplasia in primary aldosteronism were 91%(10/11) using CT and venography; 82%(9/11) using scintigraphy; and 20% (2/10) using ultrasonography. Small masses in the adrenal glands difficult to detect, especially in the left adrenal, using ultrasonography. All (4/4) phenochromocytomas were detected using either CT, ultrasonography of arteriography. However, considering their occaseonal ectopic origins and multiplicity, CT is regarded the examination of choice for such lesions. All 3 of the adrenal tumors in children were detected equally well by CT, ultrasonography and arteriography. Arteriography was especially valuable in determining their precise origins. All 3 nonfunctioning tumors were equally well detected by CT, ultrasonography and arteriography; however, CT and ultrasonography are regarded of special value in clinical follow up examinations. Metastatic adrenal tumors were detected at a rate of 92% (23/25) using CT. (J.P.N.)

    Full Text Available Introduction. Most common metastasis sites of breast cancer are the lungs, bones, liver, and brain, whereas uterine involvement by metastatic breast disease is rare. Metastatic carcinoma of the uterus usually originates from other genital sites, most commonly being from the ovaries. Invasive lobular carcinoma spreads to gynecologic organs more frequently than invasive ductal carcinoma. Case Report. A 57-year-old postmenopausal woman was diagnosed with breast carcinoma 2 years ago and modified radical mastectomy was performed. Pathological examination of tumor revealed invasive ductal carcinoma, stage IIIc. She presented with abdominal pain and distension. Diagnostic workup and gynecologic examination revealed lesions that caused diffuse thickening of the uterus wall. Endometrial sampling was performed for confirmation of the diagnosis. She underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. Breast carcinoma metastases in endometrium and myometrium were confirmed histopathologically and immunohistochemically. Conclusion. We herein report the first case of isolated uterine patient who had invasive ductal carcinoma of breast.

    Relative adrenal insufficiency (RAI) is a common finding in cirrhotic patients with severe sepsis, and increased mortality. Its significance is unknown in stable conditions. The aim of this study was to evaluate the prevalence of RAI in stable cirrhotic patients at different stages of the disease. Also, the impact of RAI on the survival was evaluated and basal cortisol levels between plasma and saliva was correlated in control subjects and cirrhotic patients. Forty seven ambulatory patients and 16 control subjects were studied. RAI was defined as a serum cortisol increase of less than 9 υg/dl from baseline after the stimulation with 250 mg of synthetic ACTH. Twenty two had Child-Pugh = 8 and 25 = 9. The prevalence of RAI in patients with stable cirrhosis was 22%. A higher incidence of RAI was observed in patients with a Child-Pugh = 9 (8/32) than in those with = 8 (3/13, p developed this complication (79% and 51%, p < 0.05, respectively). In summary, the prevalence of RAI is frequent in patients with stable cirrhosis and that it is related to the severity of liver diseaseand increased mortality. PMID:27576278

    Full Text Available Aldosterone-producing adrenocortical carcinomas are an extremely rare cause of hyperaldosteronism (<1%. Coexistence of different endocrine tumors warrants additional screening for multiple endocrine neoplasia syndromes, especially in young patients with large or malignant masses. We present the case of a 40-year-old man with a history of hypertension that presented with an incidental left adrenal tumor during an ultrasound performed for nephrolithiasis. Biochemical assessment showed a mildly elevated calcium (11.1 mg/dL, high parathyroid hormone, and a plasma aldosterone concentration/plasma renin activity ratio of 124.5 (normal < 30, compatible with primary hyperparathyroidism with a concomitant primary hyperaldosteronism. A Tc99m-MIBI scintigraphy showed an abnormally increased tracer uptake in the right superior parathyroid and abdominal computed tomography confirmed a left adrenal tumor of 20 cm. The patient underwent parathyroidectomy and adrenalectomy with final pathology reports of parathyroid hyperplasia and adrenal carcinoma with biochemical remission of both endocrinopathies. He was started on chemotherapy, but the patient developed a frontal cortex and an arm metastasis and finally died less than one year later.

    Testicular epidermoid cysts are the most common benign tumors of the testes, but account for only 1-2% of all testicular tumors. In a young man presenting with a testicular mass, a high index of suspicion must be maintained for the malignant testicular germ cell tumor, which is 50-times more common than testicular epidermoid cyst. Bilateral testicular epidermoid cysts are a very rare condition, with only a few reports in the literature. It is extremely important in this condition to make a co...

    Cathepsins are highly expressed in various human cancers, associated with tumor metastasis. It is superfamily, concluding A, B, C, D, E, F, G, H, L, K, O, S, V, and W family members. As a group of lysosomal proteinases or endopeptidases, each member has a different function, playing different roles in distinct tumorigenic processes such as proliferation, angiogenesis, metastasis, and invasion. Cathepsins belong to a diverse number of enzyme subtypes, including cysteine proteases, serine proteases and aspartic proteases. The contribution of cathepsins to invasion in human cancers is well documented, although the precise mechanisms by which cathepsins exert their effects are still not clear. In the present review, the role of cathepsin family members in cancer is discussed.

    Full Text Available Abstract The incidence of adrenal involvement in MEN1 syndrome has been reported between 9 and 45%, while the incidence of adrenocortical carcinoma (ACC in MEN1 patients has been reported between 2.6 and 6%. In the literature data only unilateral development of ACCs in MEN1 patients has been reported. We report a 31 years-old female MEN1-patient, in whom hyperplasia of the parathyroid glands, prolactinoma, non functioning pancreatic endocrine carcinoma and functioning bilateral adrenal carcinomas were diagnosed. Interestingly, a not previously described in the literature data, novel germline mutation (p.E45V in exon 2 of MEN1 gene, was detected. The association of exon 2 mutation of the MEN1 gene with bilateral adrenal carcinomas in MEN1 syndrome, should be further investigated.

    Adrenal imaging using radiopharmaceuticals is a functional test that can contribute significantly to surgical management and follow-up of patients with either benign or malignant conditions of the adrenal cortex and medulla. Imaging of the cortex is achieved by iodine-131-labeled iodomethyl nor-cholesterol (NP-59), while adrenal medulla imaging can be successfully accomplished by 131I-metaiodobenzylguanidine (MIBG), which localizes in the adrenergic nerve terminal with norepinephrine. Both tests carry high sensitivity and specificity for functional tumors and hyperplasia, and often better than CT scanning. This article reviews the current status and clinical utility of nuclear imaging of the adrenal cortex in congenital hyperplasia, low renin hypertension and aldosteronism, and Cushing's syndrome. Adrenal medulla imaging is reviewed in light of our experience at the University of Texas M.D. Anderson Cancer Center in pheochromocytoma, neuroblastoma, and other neuroectodermal tumors. Investigation of {sup 131}I-MIBG therapy of metastatic tumors of neuroectodermal origin potentially offers a means of at least controlling symptoms of hormonal secretion in these patients. 40 references.

  18. Joint survey of adrenal tumors in the kyushu-Okinawa district. Imaging characteristics of adrenal tumors

    International Nuclear Information System (INIS)

    Imaging characteristics of adrenal tumors in 183 cases experienced in the Kyushu-Okinawa district over a 2-year period from 1991 to 1992 were studied. Computerized tomography (CT) was the most accurate imaging technique for the detection of adrenal masses (detection ratio: 98.3%). Magnetic resonance imaging (MRI) was also a useful method in evaluating adrenal masses (detection ratio: 95.7%). On CT and MRI, pheochromocytoma and malignant tumor (metastatic and adrenocortical cancer) most often had an unsharply defined margin and heterogeneous structures. Eighty-two percent of cases with pheochromocytoma showed a very high signal intensity compared with that of the liver on T2-weighted images of MRI. The size of the adrenal mass was the most helpful finding in distinguishing malignancy from a benign asymptomatic adrenal lesion. Surgical exploration may be recommended for an incidental adrenal mass measuring more than 6 cm in diameter because there is a high probability for malignancy. Any lesions measuring less than 3 cm in diameter may be safely followed up, providing there is no evidence of a malignant lesion in any other organs, and providing that the CT appearance of the adrenal gland is homogeneous. The management of lesions between 3 and 6 cm in size should be individualized, by reference to other imaging characteristics. (author)

    2015-09-01

    Full Text Available Primary adrenal insufficiency is defined by the impaired synthesis of adrenocortical hormones due to an intrinsic disease of the adrenal cortex. Determining its etiology is crucial to allow adequate long-term management and genetic counseling. We report the case of a male adolescent that presented in the neonatal period with adrenal crisis and received replacement therapy for primary adrenal insufficiency. During follow-up, adrenal hypoplasia congenita (AHC was suspected given his persistently raised adrenocorticotropic hormone levels, with markedly low 17-OH progesterone and androstenedione levels. DNA sequence analysis revealed a mutation in NR0B1 gene (c.1292delG, confirming the diagnosis. Delayed puberty and persistent low levels of gonadotropins led to testosterone replacement therapy. X-linked AHC is a rare cause of primary adrenal insufficiency and hypogonadotropic hypogonadism, related to mutations in NR0B1 gene. Despite its rarity, AHC should be considered in patients who present with primary adrenal failure, low levels of 17-OH progesterone and hypogonadotropic hypogonadism.

  20. Leptomeningeal metastasis from hepatocellular carcinoma with other unusual metastases: a case report

    International Nuclear Information System (INIS)

    Leptomeningeal metastasis, which results from metastasis of tumors to the arachnoid and pia mater, can lead to the dissemination of tumor cells throughout the subarachnoid space via the cerebral spinal fluid, and frequently with a poor prognosis. The primary tumor in adults is most often breast cancer, lung cancer, or melanoma. Although leptomeningeal metastasis due to cholangiocarcinoma has been reported, to the best of our knowledge there is no cytologically confirmed report of leptomeningeal metastasis from hepatocellular carcinoma. We herein report a case of leptomeningeal metastasis from hepatocellular carcinoma in a 53-year-old woman with concomitant systemic metastases to the lung, bone, brain, kidney, adrenal gland, subcutaneous tissues, and abdominal pelvis. The neurological symptoms of the patient were relieved after treatment with methotrexate intra-cerebral spinal fluid chemotherapy concurrent with whole brain radiotherapy. To our knowledge this is the first report of leptomeningeal metastasis from hepatocellular carcinoma confirmed by cytology. Treatment with methotrexate intra-cerebral spinal fluid chemotherapy concurrent with whole brain radiotherapy was effective

    With the steep increase in the use of cross-sectional imaging in recent years, the incidentally detected adrenal lesion, or 'incidentaloma', has become an increasingly common diagnostic problem for the radiologist, and a need for an approach to classifying these lesions as benign, malignant or indeterminate with imaging has spurred an explosion of research. While most incidentalomas represent benign disease, typically an adenoma, the possibility of m alignant involvement of the adrenal gland necessitates a reliance on imaging to inform management decisions. In this article, we review the literature on adrenal gland imaging, with particular emphasis on computed tomography, magnetic resonance imaging, and photon-emission tomography, and discuss how these findings relate to clinical practice. Emerging technologies, such as contrast-enhanced ultrasonography, dual-energy computed tomography, and magnetic resonance spectroscopic imaging will also be briefly addressed. (author)

    2015-01-01

    Schwannoma is a benign neurogenic tumor originating from Schwann cells. These produce the myelin sheath that covers peripheral nerves that are often affected. This latter localization is extremely rare, and only a few case reports can be found in the medical literature. Studies have shown that approximately 0.5% to 5% of schwannomas are retroperitoneal, constituting 0.2% of adrenal incidental tumors. These usually present as incidental findings, nonsecreting adrenal masses in asymptomatic patients. Diagnosis of a schwannoma is based on detection of spindle cells with Antoni A and Antoni B regions in histological sections and positive staining for S-100 protein by immunohistochemical analysis. We report a case of an incidentally identified during an abdominal ultrasound examination with schwannoma localized in the left adrenal gland. PMID:26101687

    Full Text Available Purpose: Metastasis to adrenal gland from lung, breast, and kidney malignancies are quite common. Historically radiotherapy was intended for pain palliation. Recent studies with stereotactic body radiotherapy (SBRT including Cyberknife robotic radiosurgery aiming at disease control brings about encouraging results. Here we represent the early clinical experience with Cyberknife stereotactic system from an Indian cancer care center. The main purpose of this retrospective review is to serve as a stepping stone for future prospective studies with non- invasive yet effective technique compared to surgery. Methods: We retrospectively reviewed four cases of adrenal metastases (three: lung and one: renal cell carcinoma treated with Cyberknife SBRT. X sight spine tracking was employed for planning and treatment delivery. Patients were evaluated for local response clinically as well as with PETCT based response criteria.Results: With a median gross tumor volume of 20.5 cc and median dose per fraction of 10 Gy, two patients had complete response (CR and two had partial response (PR when assessed 8-12 weeks post treatment as per RECIST. There was no RTOG grade 2 or more acute adverse events and organs at risk dosage were acceptable. Till last follow up all the patients were locally controlled and alive. Conclusion: Cyberknife SBRT with its unique advantages like non- invasive, short duration outpatient treatment technique culminating in similar local control rates in comparison to surgery is an attractive option. World literature of linear accelerator based SBRT and our data with Cyberknife SBRT with small sample size and early follow up are similar in terms of local control in adrenal metastases. Future prospective data would reveal more information on the management of adrenal metastases.

This disorder is due to mutations in the CYP21A2 gene which is located at chromosome 6p21. The clinical features predominantly reflect androgen excess rather than adrenal insufficiency leading to an ascertainment bias favoring diagnosis in females. Treatment goals include normal linear growth velocity and "on-time" puberty in affected children. For adolescent and adult women, treatment goals include regularization of menses, prevention of progression of hirsutism, and fertility. This paper will review key aspects regarding pathophysiology, diagnosis, and treatment of NCAH.

  8. Renal and adrenal tumors. 2. rev. ed.

    International Nuclear Information System (INIS)

    In this new, second edition on diseases of the kidney and adrenal glands, research on pathological anatomy forms a solid platform from which the multiplicity of renal and adrenal tumors are discussed. Aspects as diverse as radiology, pathology, urology, pediatrics and immunology have been brought together in one book. The most up-to-date methods of tumor diagnosis by CT, NMR, and ultrasound are covered, as are methods of catheter embolization and radiation techniques in cases of primarily inoperable tumors. In this second edition the chapter on CT in particular has been revised, while the chapter on MRI is entirely new. (orig./MG)

  9. Limitations of MR imaging characterization of adrenal masses

    International Nuclear Information System (INIS)

    The ability of MR images at 1.5T to characterize 24 adrenal masses was evaluated by means of several variables recommended in the literature: (1) signal intensity ratios (adrenal-liver and adrenal-fat) at both short repetition time (TR)/short echo time (TE) (500-800/20-25) and long TR/long TE (2,000-2,500/80), (2) T2 relaxation times of adrenal masses, and (3) ratios of adrenal T2 to liver and fat T2. In the authors' series, signal intensity ratios were not reliable for characterization of adrenal masses. Adrenal T2 values were more useful: all 13 adrenal masses with T2 less than 60 msec were adenomas. However, greater than 60 msec was less specific, including four metastases, two pheochromocytomas, two adenomas, two adrenal hemorrhages, and one adrenocortical carcinoma. Ratios of T2 values were less accurate than T2 values of the adrenal gland alone. The authors conclude that T2 values of adrenal glands are more accurate than signal intensity ratios for characterization of adrenal masses at 1.5T, although masses with T2 greater than 60 msec may require biopsy

    Full Text Available Antepartum mastitis is a rare condition, whereas postpartum orlactation mastitis is a common problem. This report introducesa case of complicated bilateral antepartum mastitis, which wastreated successfully by drain insertion and antibiotic therapy.The patient was a 23-year-old woman in the 23rd week of herfirst pregnancy. Her chief complaint was progressive swelling,redness and radicular pain in both breasts, which had beenstarted gradually from the 18th week of pregnancy. The patientwas admitted to hospital, and received oral and intravenous antibioticsempirically, which was not effective. The patient wastreated by drainage and oral antibiotic therapy. Based on theapproaches employed and the outcomes achieved it is suggestedthat early surgical insertion in the presence of fluid collection inantepartum mastitis will shorten hospitalization and course ofintravenous antibiotic therapy.Iran J Med Sci 2010; 35(4: 327-330.

    2015-01-01

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    2011-07-01

    A 5.5-y-old spayed female ferret (Mustela putorius furo) with a history of adrenal disease, respiratory disease, and chronic obesity was evaluated for progressive lethargy and ataxia, diminished appetite, and possible polyuria and polydipsia. Physical examination revealed obesity, lethargy, tachypnea, dyspnea, a pendulous abdomen, significant weakness and ataxia of the hindlimbs, prolonged skin tenting, and mild tail-tip alopecia. Clinicopathologic analysis revealed severe hyperglycemia, azotemia, an increased anion gap, glucosuria, ketonuria, proteinuria, and hematuria. Abdominal ultrasonography showed hyperechoic hepatomegaly, bilateral adrenomegaly, splenic nodules, mild peritoneal effusion, and thickened and mildly hypoechoic limbs of the pancreas with surrounding hyperechoic mesentery. Fine-needle aspirates of the liver were highly suggestive of hepatic lipidosis. In light of a diagnosis of concurrent diabetic ketoacidosis and pancreatitis, the ferret was treated with fluid therapy, regular and long-acting insulin administration, and pain medication. However, electrolyte derangements, metabolic acidosis, dyspnea, and the clinical appearance of the ferret progressively worsened despite treatment, and euthanasia was elected. Necropsy revealed severe hepatic lipidosis, severe suppurative pancreatitis and vacuolar degeneration of pancreatic islet cells, a pancreatic β islet cell tumor, bilateral adrenal cortical adenomas, and myocardial fibrosis. To our knowledge, this case represents the first report of concurrent diabetes mellitus, pancreatitis, pancreatic β islet cell tumor (insulinoma), and adrenal disease in a domestic ferret. The simultaneous existence of 3 endocrine diseases, pancreatitis, and their associated complications is a unique and clinically challenging situation. PMID:21838985

    AIM:To investigate the clinical features and prognostic factors of advanced hepatocellular carcinoma (HCC) patients presenting with lung metastasis at initial diagnosis.METHODS:Between 2001 and 2010,we recruited 76consecutive HCC patients initially presenting with lung metastasis,without co-existing metastasis from other sites.These patients were divided into three groups:untreated group (n =22),single treatment group (n =19),and combined treatment group (n =35).RESULTS:Metastasis of bilateral lung lobes was common and noted in 35 patients (46.1%),and most of patients (59/76,77.6%) presented with multiple lung metastatic nodules.Nineteen patients (25.0%)received single-method treatment,including hepatectomy in 4,transcatheter arterial chemoembolization in 6,radiotherapy in 5,and oral sorafenib in 4.Thirty-five patients (46.1%) received combined treatment modalities.The overall median survival of the all patients was 8.7 ± 0.6 mo; 4.1 ± 0.3,6.3 ± 2.5 and 18.6 ± 3.9 mo,respectively in the untreated group,single treatment group and combined treatment group,respectively,with a significant difference (log-rank test,P < 0.001).Multivariate analysis revealed that Child-Pugh score,the absence or presence of portal vein tumor thrombus,and treatment modality were three independent prognostic factors affecting survival of patients with advanced HCC and concomitant lung metastasis.CONCLUSION:Combined treatment modalities tend to result in a better survival as compared with the conservative treatment or single treatment modality for HCC patients initially presenting with lung metastasis.

  17. Role of adrenal catecholamines in cerebrovasodilation evoked from brain stem

    International Nuclear Information System (INIS)

    The authors studied whether adrenal medullary catecholamines (CAs) contribute to the metabolically linked increase in regional cerebral blood flow (rCBF) elicited by electrical stimulation of the dorsal medullary reticular formation (DMRF). Rats were anesthetized, paralyzed, and artificially ventilated. The DMRF was electrically stimulated with intermittent trains of pulses through microelectrodes stereotaxically implanted. Blood gases were controlled and, during stimulation, arterial pressure was maintained within the autoregulated range for rCBF. rCBF and blood-brain barrier (BBB) permeability were determined in homogenates of brain regions by using [14C]iodoantipyrine and α-aminoisobutyric acid (AIB), respectively, as tracers. Plasma CAs (epinephrine and norepinephrine) were measured radioenzymatically. DMRF stimulation increased rCBF throughout the brain and elevated plasma CAs substantially. Acute bilateral adrenalectomy abolished the increase in plasma epinephrine, reduced the increases in flow in cerebral cortex, and abolished them elsewhere in brain. They conclude that the increases in rCBF elicited from the DMRF has two components, one dependent on, and the other independent of CAs. Since the BBB is impermeable to CAs and DMRF stimulation fails to open the BBB, the results suggest that DMRF stimulations allows, through a mechanism not yet determined, circulating CAs to act on brain and affect brain function

    BACKGROUND: Juvenile nasopharyngeal angiofibroma is a benign, vascular tumour that primarily occurs in adolescent males. Despite its benign nature, aggressive growth patterns can cause potential life-threatening complications. Juvenile nasopharyngeal angiofibroma is normally unilateral, originati...... with bilateral symptoms. Our management, including successful pre-operative planning, enabled one-step total removal of both tumours and rapid patient recovery....... from the sphenopalatine artery, but bilateral symptoms can occur if a large tumour extends to the contralateral side of the nasopharynx. This paper presents the first reported case of true bilateral extensive juvenile nasopharyngeal angiofibroma involving clinically challenging pre-surgical planning...... bilateral embolisation. Radical removal performed as one-step, computer-assisted functional endoscopic sinus surgery was performed. The follow-up period was uncomplicated. CONCLUSION: This case illustrates the importance of suspecting bilateral juvenile nasopharyngeal angiofibroma in patients presenting...

  19. Adrenal incidentalomas: A collection of six interesting cases and brief review of literature

    Directory of Open Access Journals (Sweden)

    Roopal Panchani

    2012-01-01

    Full Text Available Introduction: Adrenal incidentalomas (AI are detected in approximately 4-7% of patients in imaging studies. Majority are benign, but careful evaluation is warranted to rule out carcinoma and functional adenomas. Aim: The purpose of presenting these cases is to highlight the approach to management of AI in terms of diagnosis, follow-up, and treatment. Materials and Methods: Seven patients presenting in the endocrine clinic with AI were evaluated for their presenting clinical features and investigated. Results: Case 1 was a 49-year-old female, with adrenal androgen secreting adrenocortical carcinoma with amenorrhoea which was mistaken as menopause. She had minimal hirsutism, which was mistaken as postmenopausal hirsutism. Case 2 was a 39-year-old male, presenting with hyperglycemia found to have Conns′ syndrome with aldosterone producing adenoma on routine ultrasound. Case 3 was a 32-year-old male, presenting with gastritis and bloating, where ultrasound showed bilateral large adrenal masses revealed as diffuse large B cell lymphoma on biopsy. Case 4 was a 21-year-old boy, who had pheochromocytoma misdiagnosed as benign intracranial hypertension (HTN. Case 5 was a 59-year-old hypertensive male, presenting with fever had pheochromocytoma with catecholamine excess, producing fever. Case 6 was isolated adrenal tuberculosis who presented with chronic diarrhea. Conclusion: AI are common, though prevalence varies depending on the reason for scanning, the characteristics of the population studied, and the radiological techniques used. Most are non-secreting cortical adenomas. AI should be evaluated both biochemically and radiologically. When a hormonal disorder is suspected clinically, targeted, diagnostic testing for autonomous cortisol secretion, pheochromocytoma, and hyperaldosteronism is indicated.

  20. Early diagnosis of and surgical strategy for adrenal medullary disease in MEN II gene carriers

    International Nuclear Information System (INIS)

    Sixteen multiple endocrine neoplasia type II (MEN II) gene carriers--12 who had undergone thyroidectomy because of medullary carcinoma of the thyroid and 4 whose thyroid glands had been removed because of C cell hyperplasia--were examined for the presence of pheochromocytomas. No patient had sought medical advice for pheochromocytoma symptoms. Fourteen patients had MEN IIa syndromes, one patient had a MEN IIb and another patient had a mixed syndrome of von Recklinghausen's neurofibromatosis and MEN II. Eight patients had undergone unilateral adrenalectomy for pheochromocytoma 11 +/- 4 years before. The patients underwent clinical examination, determination of the urinary excretion of catecholamines and metabolites, and 131I-metaiodobenzylguanidine (131I-MIBG) and CAT scans. 131I-MIBG scanning was performed with images 1, 4, and 7 days after the radionuclide injection. In seven of eight patients who had undergone unilateral adrenalectomies, the 131I-MIBG scans showed accumulation of the radionuclide in the remaining adrenal gland. Bilateral adrenal accumulation of the radionuclide was demonstrated in seven of eight MEN IIa gene carriers who had not undergone adrenalectomy. Five patients, two of whom had undergone adrenalectomy, were found to have unilateral pheochromocytomas less than 2 cm in diameter. Only one of these five patients had an elevated excretion of urinary catecholamines. Between day 4 and day 7 after 131I-MIBG injection, adrenal glands with pheochromocytomas increased their relative accumulation of the radionuclide significantly more (p less than 0.02) than did adrenal glands without any demonstrable pheochromocytomas. All the pheochromocytomas were viewed by means of CAT scans

  1. Ultrasound follow up of testicular adrenal rest tumors with congenital adrenal hyperplasia: Report of three cases

    International Nuclear Information System (INIS)

    While testicular adrenal rest tumor is generally a rare intratesticular tumor, it is frequent in patients with congenital adrenal hyperplasia. The tumors are diagnosed and followed up by ultrasound examination because these tumors are non-palpable and symptomless in most cases and always benign. Ultrasound imaging features change depending on how congenital adrenal hyperplasia is controlled. We herein report three cases of testicular adrenal rest tumors with different usual and unusual imaging findings and follow-up imaging. Patient 1 was a 14-year-old boy who presented with poor compliance to medication. Patient 2 and 3 were a 10-year-old and 13-year-old boy who presented with precocious puberty and short stature, respectively. Ultrasound examinations demonstrated oval hypoechoic masses and irregular speculated hyperechoic masses in the testes and different serial imaging findings

    Full Text Available Incidental adrenal tumors are lesions occasionally observed during abdominal US or CT scans. These tumors have been observed in patients without clinical or laboratorial signs of adrenal disease. The authors report a case of a 18 - years - old young man who was admitted to the Franco da Rocha Hospital, São Paulo, with abdominal pain and a palpated mass in the epigastrium which began one month ago. These findings were preceeded by a blunt trauma at the epigastrium three months earlier. First clinical hypothesis was of a traumatic pancreatic pseudocyst. However, investigation and laparotomy showed a large left adrenal solid mass, weighting 700 g. The mass was removed and histology was performed. There was no evidence of malignant neoplasm, then the diagnostic of incidental adenoma of adrenal was confirmed. The authors hope to stimulate surgeons for early detection of these lesions in order to prevent the complications and improve the prognosis.

  3. Diagnosis of adrenal adenoma and hyperplasia by CT and adrenal scintigraphy

    International Nuclear Information System (INIS)

    The evaluation of X-CT and adrenal scintigraphy in diagnosis of Cushing syndrome and primary aldosteronism was studied in 18 patients. In Cushing syndrome, CT appearance of adenoma is commonly larger than that of primary aldosteronism and cleary deliniated by surrounding fat. So, in Cushing syndrome, diagnosis of adenoma on CT is much easier than that of primary aldosteronism, and absence of adenoma on CT suggests adrenal hyperplasia. In primary aldosteronism both of CT and scintigraphy must be performed. (author)

    Full Text Available Co-occurrence of adrenal incidentaloma with hypertension calls for evaluation of endocrine causes including pheochromocytoma, Cushing′s disease, and primary aldosteronism. We are reporting 40-years-old man who presented with hypertension and adrenal mass. He had elevated metanephrines, histology of resected adrenal mass revealed adrenal myelolipoma, and immuno-histochemistry was positive for chromogranin A. Both his blood pressure and urinary metanephrines returned to normal after surgery. The association of hypertension and adrenal myelolipoma may not be entirely coincidental, as it may be associated with secreting catecholamine. Literature on such an uncommon association is reviewed briefly as well.

    Full Text Available Introduction: Hydatid cyst of the adrenal gland is extremely rare even in generalized hydatid disease, with less than 20 cases reported in world literature including those found in autopsy. Case outline: The authors present the second case of the adrenal gland hydatid cyst described in Serbian literature, in 52-year old woman. During the investigation for the epigastric pain by ultrasonography and computed tomography, calcified cyst of the sixth segment of the liver, 44Ч39 mm in diameter, was diagnosed. However, during an open surgery, it turned out to be the cyst of the right adrenal gland. The cyst as well as the entire adrenal gland was removed. The hydatid nature of the cyst was confirmed by histological examination. The postoperative recovery was uneventful. The patient has remained symptom-free over two years after the surgery. Conclusion: To the best of our knowledge, this is the second case reported in Serbian and 18th case published in world literature.

  6. Adrenal insufficiency in patients with decompensatedcirrhosis

    Institute of Scientific and Technical Information of China (English)

    2015-01-01

    Adrenal reserve depletion and overstimulation of thehypothalamus-pituitary-adrenal (HPA) axis are causesfor adrenal insufficiency (AI) in critically ill individuals.Cirrhosis is a predisposing condition for AI in cirrhotics aswell. Both stable cirrhotics and liver transplant patients(early and later after transplantation) have been reportedto present AI. The mechanisms leading to reducedcortisol production in cirrhotics are the combination oflow cholesterol levels (the primary source of cortisol), theincreased cytokines production that overstimulate andexhaust HPA axis and the destruction of adrenal glandsdue to coagulopathy. AI has been recorded in 10%-82%cirrhotics depending on the test used to evaluate adrenalfunction and in 9%-83% stable cirrhotics. The similarityof those proportions support the assumption that AI isan endogenous characteristic of liver disease. However,the lack of a gold standard method for AI assessmentand the limitation of precise thresholds in cirrhoticsmake difficult the recording of the real prevalence of AI.This review aims to summarize the present data overAI in stable, critically ill cirrhotics and liver transplantrecipients. Moreover, it provides information about thecurrent knowledge in the used diagnostic tools and thepossible effectiveness of corticosteroids administration incritically ill cirrhotics with AI.

  7. Adrenal myelolipoma: Diagnosis by MR imaging

    International Nuclear Information System (INIS)

    Myelolipoma is an uncommon, benign, adrenal lesion composed of fatty tissue and bone marrow elements. The presence of fat within this tumor is the key factor in identification and noninvasive diagnosis with imaging methods. Since fat has a characteristic behavior reflected by the MR signal intensity, a specific diagnosis can be made by MRI. (orig.)

  8. Adrenal Insufficiency - Aetiology, Diagnosis and Treatment

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available Adrenal insufficiency is caused by either primary adrenal failure or by hypothalamic-pituitary impairment of the corticotropic axis. Adrenal insufficiency, first codified in 1855 by Thomas Addison, remains relevant in 2014 because of its lethal nature. Though, it is a rare disease but is life threatening when overlooked. Main presenting symptoms such as fatigue, anorexia and weight loss are nonspecific, thus diagnosis is often delayed. The diagnostic work-up is well established but some pitfalls remain. The diagnosis is adequately established by the 250 μg ACTH (adrenocorticotropic hormone stimulation test in most cases. Glucocorticoids provide life saving treatment but long-term quality of life is impaired, perhaps because therapy is not given in a physiologic way. Dehydroepiandrosterone-replacement therapy has been introduced that could help to restore quality of life. It may be useful in pubertal girls, but not in adults. Monitoring of glucocorticoid-replacement is difficult due to lack of objective methods of assessment and is therefore largely based on clinical grounds. Thus, long-term management of patients with adrenal insufficiency remains a challenge, requiring an experienced specialist.

  9. Retinoblastoma presenting as metastasis

    International Nuclear Information System (INIS)

    Objective: The purpose of this study was to evaluate the frequency of metastatic retinoblastoma on initial presentation. Design: Prospective study. Place and duration of study: Supra Regional Centre for Retinoblastoma, Department of Ophthalmology, Khyber Teaching Hospital Peshawar Pakistan from July 1, 1999 to January 31, 2003. Methods: Data was collected from 80 registered Retinoblastoma patients admitted and examined under anaesthesia for tumours assessment. Diagnosis was supported with the help of CT scan and confirmed by histopathology of the enucleated specimen for evidence of optic nerve invasion by the tumour. Results: Twenty (25%) patients were presenting as Metastasis on initial presentation. Mean age was 3.5 years, range was 7 months to 12 years. Out of these 20 patients with metastasis, 10 were male and 10 were female. Eighteen (90%) of them were from lower socio-economic group. Conclusion: Failure in early diagnosis of retinoblastoma, advance age and unilateral disease are associated with extraocular spread; this tragic scenario can be prevented best be early detection and prompt treatment plan implementation.

  10. Computed tomography of the adrenals in patients with tuberculosis

    International Nuclear Information System (INIS)

    We evaluated the adrenals of individuals without tuberculosis (group 1 - G1) and with tuberculosis (group 2 - G2) using computed tomography. The antero-posterior length, the thickness, and the longitudinal length of the adrenals were compared in G1 and G2. The duration of the disease, the occurrence of morphologic abnormalities in G2, the distribution according to sex, age and skin color were also studied. There was difference in the antero-posterior length and thickness of right adrenal between G1 and G2. A higher prevalence of white skin male individuals was observed in G2. There was no association between duration of the disease and the occurrence of morphologic abnormalities in G2. A higher occurrence of adrenal enlargement was observed in G2. The main computed tomography findings in patients with tuberculosis were enlargement of the adrenal without calcification, enlargement of the adrenal with punctiform calcifications, and residual calcification of the adrenal.

  11. MR characterization of adrenal masses by T1-weighted imaging

    International Nuclear Information System (INIS)

    Differentiation of benign from malignant adrenal masses was investigated using a T1-weighted (echo time, 20 msec; repetition time, 250 msec) spin-echo sequence at 0.5 T. Of 35 adrenal masses studied, all those with adrenal mass/liver intensity ratios ≤0.71 were metastases, and all with ratios ≥0.78 were adenomas. Using adrenal mass/fat intensity ratios, eight of nine masses with ratios ≤0.35 were metastases, and all with ratios ≥0.42 were benign. Of the masses, 31% were indeterminate using adrenal/liver and 29% using adrenal/fat intensity ratios. Similar overlap has been reported for T2-weighted imaging techniques. These data suggest that T1-weighted imaging has a specificity similar to that reported for T2-weighted imaging in characterizing adrenal masses, but allows shorter scan times and provides better anatomic resolution

    2016-01-01

    Glioblastoma multiforme (GBM) is the most common malignant central nervous system tumor; however, extraneural metastasis is uncommon. Of those that metastasize extraneurally, metastases to the vertebral bodies represent a significant proportion. We present a review of 28 cases from the published literature of GBM metastasis to the vertebra. The mean age at presentation was 38.4 years with an average overall survival of 26 months. Patients were either asymptomatic with metastasis discovered at autopsy or presented with varying degrees of pain, weakness of the extremities, or other neurologic deficits. Of the cases that included the time to spinal metastasis, the average time was 26.4 months with a reported survival of 10 months after diagnosis of vertebral metastasis. A significant number of patients had no treatments for their spinal metastasis, although the intracranial lesions were treated extensively with surgery and/or adjuvant therapy. With increasing incremental gains in the survival of patients with GBM, clinicians will encounter patients with extracranial metastasis. As such, this review presents timely information concerning the presentation and outcomes of patients with vertebral metastasis. PMID:26704201

  13. Accuracy of dynamic MR imaging versus CT for evaluation of adrenal masses in patients with malignant diseases

    International Nuclear Information System (INIS)

    CT examinations, precontrast MR images, and fast contrast-enchanced dynamic MR studies have been evaluated retrospectively in 44 patients with known malignant disease of different origins and unilateral (n = 36) or bilateral (n = 8) adrenal masses. Size, shape, attenuation, and signal intensity on T2-weighted images and pattern of Gd- DTPA enhancement were analyzed in all patients. Dynamic studies were performed with repeated imaging up to 16 minutes after Gd-DTPA administration. Masses with moderate enhancement and complete washout after 10 minutes were considered adenomas. Diagnosis was verified by means of surgery, biopsy or follow up. CT had an overall accuracy of 0.62; precontrast MR imaging, 0.76, dynamic MR imaging, 0.85. The simultaneous use of precontrast MR imaging and dynamic contrast-enhanced studies led to an accurate diagnosis of 92% and thus should be considered in all cases of suspected or unclear adrenal masses in patients with known malignant disease

    Peter Gassman

    2011-07-01

    Full Text Available The development of secondary distant organ and lymph node metastasis has an extraordinary impact on the prognosis of patients with solid cancer. In most cases the advent of metastatic growth represents the turning point from a local, potentially curable, disease to a systemic non-curable situation. As a highly regulated process, metastasis formation follows a distinct, non-random pattern characteristic for each tumor entity. Metastasis formation and strategies to prevent this lethal event in the progression of cancer is of fundamental interest for cancer science and patient care. In this special issue of Cancers, papers highlighting cellular mechanisms of metastasis formation, genetic and epigenetic aspects associated with organ and tumor specific metastasis formation, as well as papers outlining experimental and clinical therapeutic concepts for anti-metastatic treatment are included.

    We present a case of acute silicosis with bilateral pneumothorax of a 28-year-old man working at a stone crusher factory for 1 year. He presented to the emergency department with cough, respiratory distress and diffuse chest pain. The patient was managed with bilateral intercostal tube drainage under water seal, oxygen inhalation and conservative therapy. On follow-up he showed improvement of resting dyspnoea and was doing well. This case is being reported because of the rare complications of acute silicosis as bilateral pneumothorax. PMID:24862410

  16. Patterns of regional lymph node metastasis of nasopharyngeal carcinoma: A meta-analysis of clinical evidence

    International Nuclear Information System (INIS)

    The characteristics of cervical lymphatic metastasis in nasopharyngeal carcinoma (NPC) are not completely understood. As such, radiotherapy to the entire lymphatic of the neck bilaterally has been empirically practiced even in early stage disease, although not supported by clinical evidence. We studied the pattern and probability of nodal metastasis through a meta-analysis of published evidences, with an aim to establish an evidence-based guideline for selecting and delineation of clinical target volume of neck lymphatics for conformation radiation for NPC. A literature search yielded an initial 411 original articles, and 13 studies with 2920 NPC cases staged via MRI were included in this analysis. The occurrence of nodal metastasis was calculated and analyzed according to the respective regional nodal levels. 85% of NPC cases presented with lymphadenopathy. The most commonly involved regions include retropharyngeal (69%) and level II lymph nodes (70%). The overall probability of levels III, IV, and V nodal involvement are 45%, 11%, and 27%, respectively. Low-risk node groups included the supraclavicular, levels IA/IB and VI nodes, and parotid nodes with involvement rates at 3%, 0%, 3%, 0%, and 1%, respectively. Nodal metastases followed an orderly pattern and the probability of 'skip' metastasis between levels varied between 0.5-7.9%. Lymph node metastasis in NPC follows a predictable and orderly pattern. The rarity of metastasis in certain nodal groups and 'skip' metastasis suggest that reduced treatment volume is feasible in conformal radiotherapy for NPC

  17. Bilateral support programmes

    International Nuclear Information System (INIS)

    In the Russian Federation, serious consideration is being given to the safety of nuclear facilities and to security of nuclear material. One important factor in ensuring security of nuclear material and facilities is physical protection. The Ministry of Atomic Energy of the Russian Federation is making great efforts to improve physical protection of nuclear facilities. Some of the measures which are being implemented to improve physical protection are being carried out in the framework of international co-operation in this field. To date, the Russian Federation has established bilateral co-operation with the United States of America, Germany, Belgium, France and Finland, and has studied and taken account of the experience of foreign countries in the field of physical protection and nuclear material accounting and control. At present, over 20 enterprises of the Ministry of Atomic Energy of the Russian Federation representing all the main branches of the nuclear activities of the Ministry are involved in international co-operation on physical protection and nuclear material accounting and control. The main branches of this co-operation are as follows: Scientific and technical co-operation; production of a conceptual design to improve physical protection systems directly at nuclear risk facilities; swift improvement of physical protection (without developing design documentation for the nuclear risk facility as a whole); reinforcement of physical protection during the transport of nuclear material; and training of staff at nuclear risk facilities. During this work, many facilities were equipped with modern physical protection and with nuclear material accounting and control equipment. The Ministry of Atomic Energy of the Russian Federation is pleased with the results of this international co-operation and feels that it should continue. (author)

    Laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. A case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. The patient had dyspnea, cough, and excessive phlegm for a month and a late onset stridor. Flexible nasopharyngolaryngoscopy showed bilateral cystic enlargements of the false vocal folds and true vocal folds could not be visualized. Laryngeal CT without contrast enhancement showed bilateral internal laryngoceles. Submucosal total excision of bilateral cystic masses including parts of false vocal folds was performed. The symptoms resolved immediately after surgery. Although the incidence of internal laryngocele is rare, it should be remembered in the differential diagnosis of upper airway problems and diagnostic flexible nasopharnygolaryngoscopy is routinely indicated for airway evaluation in at-risk patients.

  3. The role of radiolabeled somatostatin analogs in adrenal imaging

    International Nuclear Information System (INIS)

    We investigated the role of radiolabeled somatostatin analogs (SAs) in adrenal imaging. We evaluated 15 patients (6 men and 9 women, mean age 47 ± 17 years) with imaging-detected adrenal tumors. Patient population was divided into two groups on the basis of the nature of adrenal lesions. Group 1 consisted of patients with benign adrenal lesions (n = 10). Group 2 consisted of patients with malignant adrenal lesions (n = 5). Pathology examinations were obtained in 13 cases: 7 pheochromocytomas, 2 adenomas, 2 cysts, 1 carcinoma, and 1 fibro-histiocytoma. One patient had a proven diagnosis of non-small-cell lung cancer associated with the presence of a right adrenal mass. The last patient had a clinical diagnosis of Werner syndrome associated with the presence of a large left adrenal mass. All patients underwent scintigraphic studies using radiolabeled SAs, of which indium-111 (In-111) pentetreotide was used in 11 cases and technetium-99m (Tc-99m)-labeled peptides (P-587 or P-829) were used in the remaining four cases. No significant labeled SAs uptake was observed in the majority (8 of 10, 80%) of the benign adrenal lesions (Group 1); however, increased uptake was found in two benign pheochromocytomas. Conversely, significant labeled SAs uptake was observed in the majority (4 of 5, 80%) of the malignant adrenal lesions (Group 2); however, the last lesion (carcinoma) did not show abnormal uptake. Results of this study show that the majority of benign adrenal tumors do not concentrate radiolabeled SAs; conversely, the majority of malignant adrenal lesions show significant SAs uptake, suggesting the presence of somatostatin receptors. This finding may allow the use of somatostatin as a treatment agent in malignant adrenal tumors. Thus, the main role of labeled SAs in adrenal imaging consists of lesion characterization rather than tumor detection and localization

    Objective Report on the 7-year experience with bilateral ophthalmic artery chemosurgery (OAC-Tandem therapy) for bilateral retinoblastoma. Design Retrospective, single institution study. Subjects 120 eyes of 60 children with bilateral retinoblastoma treated since March 2008. Methods Retrospective review of all children treated at Memorial Sloan Kettering with bilateral ophthalmic artery chemosurgery (Melphalan, Carboplatin, Topotecan, Methotrexate) delivered in the same initial session to both naïve and previously treated eyes. Main Outcome Measures Ocular survival, metastatic disease, patient survival from metastases, second cancers, systemic adverse effects, need for transfusion of blood products, electroretinogram before and after treatment. Results 116 eyes were salvaged (4 eyes were enucleated: 3 because of progressive disease, 1 family choice). Kaplan Meier ocular survival was 99.2% at one year, 96.9% at 2 and 3 years and 94.9% for years 4 through 7. There were no cases of metastatic disease or metastatic deaths with a mean follow-up of 3.01 years. Two children developed second cancers (both pineoblastoma) and one of them died. Transfusion of blood products was required in 3 cases (4 transfusions), 1.9%. Two children developed fever/neutropenia requiring hospitalization (0.95%). ERGs were improved in 21.6% and unchanged after treatment in 52.5% of cases (increase or decrease of less than 25μV). Conclusions Bilateral ophthalmic artery chemosurgery is a safe and effective technique for managing bilateral retinoblastoma-even when eyes are advanced bilaterally, and if both eyes have progressed after systemic chemotherapy. Ocular survival was excellent (94.9% at 8 years), there were no cases of of metastatic disease and no deaths from metastatic disease, but children remain at risk for second cancers. In 21.6% of cases ERG function improved. Despite using chemotherapy in both eyes in the same session, systemic toxicity was low. PMID:27258771

  5. Immunologic, hemodynamic, and adrenal incompetence in cirrhosis

    DEFF Research Database (Denmark)

    Risør, Louise Madeleine; Bendtsen, Flemming; Møller, Søren

    2015-01-01

    Acute kidney injury (AKI) is one of the most severe complications of cirrhosis and is associated with significant morbidity and mortality. Liver fibrosis and liver insufficiency, portal hypertension, systemic vasodilation, and a subsequent hyperdynamic circulation undermine the renal and cardiac...... function, making cirrhotic patients more susceptible to hemodynamic incidents. In addition, the immune system is impaired in cirrhosis, leading to an exaggerated production of vasoactive mediators, and the adrenal cortisol response is insufficient, which causes further impairment of the vascular tonus...... dysfunction, but is not responsive to volume expansion. Recent research indicates that development of hepatic nephropathy represents a continuous spectrum of functional and structural dysfunction and may be precipitated by the inherent immunologic, adrenal, and hemodynamic incompetence in cirrhosis.

The possibility of this mass developing in a supernumerary kidney was ruled out, since no identifiable renal tissue, pelvis or ureters was seen within the mass, nor was any separate systemic arterial supply to the mass seen. The diagnosis of extra-renal clear cell RCC was based on cyto-morphological features, further confirmed by immunohistochemistry findings. The origin of this extra-renal clear cell renal cell is proposed to be from the mesodermal embryonic rests.

    Full Text Available Pheochromocytoma and bilateral renal artery stenosis have a quite rare association. Although unilateral renal artery stenosis is reported in the literature with Pheochromocytoma but bilateral renal artery stenosis never reported before in Gulf region. A 56-years-old woman primarily referred to our facility for CABG for triple vessel disease but uncontrolled blood pressure and long standing history of hypertension rendered her for further investigations for secondary causes. The technical imaging techniques (USG, abdominal CT, magnetic resonance angiogram (MRA revealed bilateral renal artery stenosis and left supra-adrenal mass. Further hormonal assays confirmed high catecholamine and raised rennin and aldosterone secondary to Pheochromocytoma and bilateral renal artery stenosis. Laparoscopic removal of Pheochromocytoma with minimum invasive reconstructive surgery for bilateral renal artery stenosis was planned prior to CABG for triple vessel disease but patient declined any surgery or interventional and opted for conservative management inspite of repeated counselling sessions with the patient. Although these conditions co-existed simultaneously but differ in management.

  11. Genitourinary MR: Kidneys and adrenal glands

    International Nuclear Information System (INIS)

    Due to its high tissue contrast and multiplanar imaging capabilites, MRI provides a detailed display of renal and adrenal anatomy. Recent technical developments overcoming the problem of respiration induced motion artifacts and the use of paramagnetic contrast agents have further improved the performance of MRI which has now evolved as an alternative or complementary imaging modality to ultrasound, excretory urography and computed tomography. Dynamic contrast-enhanced studies will usually allow to detect even small enhancing solid areas within the cyst wall. Use of a fast (turbo) spoiled gradient echo sequence allows for assessment of contrast enhancement dynamics in renal and adrenal masses. For tumor staging, the multiplanar imaging capabilities of MRI are advantageous. Perinephric extent is best detected using opposed-phase GRE images resulting in an artifical accentuation of renal contours. Extension into venous structures is best diagnosed by using a GRE sequence allowing for distinction between flowing blood and tumor thrombus. Noninvasive differentiation of adrenal lesions can be performed with an unprecedented accuracy using chemical-shift imaging. (orig.)

  12. The kidney, adrenal gland, and retroperitoneum

    International Nuclear Information System (INIS)

    Although its unparalleled tissue contrast resolution and multiplanar imaging capability, and the fact that it does not require exogeneous contrast agents, allow very detailed anatomic delineation of retroperitoneal anatomy in a safe and completely noninvasive fashion, magnetic resonance imaging (MRI) cannot at this time be used a screening procedure for evaluation of the adrenal glands and kidneys. At present, MRI remains time-consuming and expensive when compared with conventional X-ray computed tomography (X-ray CT), sonography, and quantitative scintigraphy. It is recommended, rather, that MRI can be reserved for situations in which its particular advantages can be expected to resolve questions raised by other imaging modalities. For example, MRI can be used t characterize an adrenal mass detected by CT, to evaluate extension of renal or adrenal neoplasms into adjacent organs when CT findings are equivocal, to assess vascular patency when intravenous contrast material is contraindicated or CT findings are equivocal, and to evaluate the cause of renal allograft failure when findings with other radiologic modalities are inconclusive and biopsy is medically contraindicated. Evaluation of the cause of ureteral obstruction and detection of calculi or lesional calcification are more reliably achieved with CT

    Full Text Available Context: According to the recent World Health Organization reports, lung cancer has become the most common type of malignancy and the leading cause of death from cancer. Lung cancer frequently metastasizes to hilar lymphnodes, brain, adrenal glands, bone, but rarely to skin. Case Report: We report a case of a 72-year-old male with a past medical history of pulmonary fibrosis and no prior history of smoking who presented to the emergency room for progressive dyspnea over three weeks. The patient reported having a rapidly growing scalp lesion as well. A computed tomography (CT scan of the chest showed diffuse fibrotic changes and multiple densities of different diameters; a CT guided biopsy of lung revealed a poorly differentiated adenocarcinoma. Excision of right scalp lesion was performed, and pathology revealed poorly differentiated malignant neoplasm favoring adenocarcinoma. Conclusion: We are presenting a rare case of lung adenocarcinoma presenting with skin metastasis, which was simultaneously diagnosed during the same hospitalization. Although cutaneous metastasis from the lung is rare, it must be ruled out in patients with suspicious skin lesions, smoking history, or lung cancer.

    Bilateral breast cancer incidence is appreciated to be between 0.3 to 12% and is determined either by a hereditary load associated with chromosomal instability under the effect of environmental factors, or by the evolution in a particular hormonal context which gives biological aggressiveness. We present the case of a patient, aged 38 years, clinically, imagistic and bioptic diagnosed with left axillary lymph node metastases of breast carcinoma NST invasive G3, IHC-RE = 60%, RP = 30%, HER2neu = 2 +, Ki67 = 20%, in August 2013. Patient followed neoadjuvant chemotherapy treatment during September-October 2013. In December 2013 she was clinically and imaging diagnosed with bilateral breast cancer, for which surgical intervention was done which consisted of bilateral radical Madden mastectomy with bilateral axillary lymphadenectomy. BAP-invasive carcinoma NST: left breast-pT2mN3a G2, right breast--pT3mN3a G2, IHC-RE = 90%, RP =70% HER2neu = 2 +, Ki67 = 50%. During the period of January-March 2014, the patient followed adjuvant chemotherapy and Herceptin. Bilateral breast ultrasound assessment in April 2014 revealed: left axilla--liquid blade 29 / 6mm; right axilla--oval ganglion 9/5 mm. Abdominal and pelvic ultrasound: empty uterine cavity, bosselated contour; at left ovary level multiple cystic formations. During the period of May-June 2014, adjuvant radiation therapy and ovarian irradiationwas administered to the patient. Subsequently hormone therapy was initiated. Following CHT / ovarian irradiation patient continues to experience intermittent uterine bleeding, which is why a total hysterectomy with bilateral ovariectomy was done, and BAP: cervical, endometrialand left ovary with tumor multifocal infiltration with histopathological aspect of invasive breast carcinoma NST. Periodic imaging evaluations do not reveal local or distant recurrence. The particularity of this case is synchronous bilateral breast cancer diagnosis in a young patient complicated in its

  16. A comparative study of the accuracy in locating adrenal lesions between CT, adrenal imaging and angiography

    International Nuclear Information System (INIS)

    This study was undertaken to compare the accuracy in locating adrenal lesions between CT, adrenocortical imaging and angiography in a total of 30 cases of adrenal diseases; 15 of primary aldosteronism, 8 of pheochromocytoma (9 tumors), 4 of Cushing's syndrome and 3 of adrenogenital syndrome. The correct localization was obtained in 90%(27/30) in CT, 94%(29/31) in adrenocortical imaging, 100%(15/15) by arteriography and 90%(18/20) in venography. However the locating accuracy decreased to 83%(15/18) in arteriography and 67%(18/27) in venography when the technically failed cases were included. These results suggest that CT and adrenocortical imaging are sufficient to detect adrenal lesions in most cases. Ambiguous cases in these noninvasive methods may be the subjects for angiography.

    Ten patients with endobronchial metastasis from primary breast cancer were found among 1200 fibreoptic bronchoscopies. Six of these patients had radiological signs suggesting bronchial obstruction. The diagnosis was verified in nine cases by means of bronchoscopic biopsy or cytology and in one by thoracotomy. Endobronchial metastasis should be considered when symptoms or chest films suggest endobronchial disease in a patient with a history of breast cancer.

  3. Dynamic MR imaging of adrenal masses at 0.5 T

    International Nuclear Information System (INIS)

    The purpose of this study is to determine the clinical efficacy of dynamic MR imaging at 0.5 to diagnose adrenal masses. The series consisted of 19 patients with 20 lesions, including five pheochromocytomas, four adrenocortical adenomas, eight metastatic tumors and three neurinomas of juxtaadrenal regions. We used a superconducting magnet of Toshiba (MRT-50A). Sequential gradient-echo images (TR/TE=100/14 ms, flip angle 60deg) were obtained every two minutes after an intravenous administration of Gd-DTPA. Relative mass-to-fat signal intensity ratios (IM/IF) were calculated on all images. In some cases of pheochromocytomas, the IM/IF values showed signigicant increase immediately after the administration, with faint washout of the contrast material. Some cases of adrenocortical adenomas also showed maximum IM/IF values just after the administration, but the washout was fast. However, other cases of pheochromocytomas and adrenocortical adenomas showed neither strong contrast uptake nor rapid washout. In the cases of neurinomas, highest IM/IF values were noted at five to nine minutes. On the other hand, metastatic tumors showed no definite patterns of time related change of IM/IF values, therefore it was difficult to differentiate metastases from other tumors. In some particular cases, dynamic MR images at 0.5 T may help to specify adrenocortical adenoma, pheochromocytoma, or neurinoma. However, this method does not contribute to differentiate adrenal masses, since metastasis cannot be ruled out in all cases. (author)

  5. Addison's disease with adrenal enlargement on sonography and computed toimography

    International Nuclear Information System (INIS)

    One of the major causes of chronic adrenal insufficiency (Addison's disease) is tuberculous adrenalopathy. Since sonography and computed tomography have become generally available in recent years and are of potential help in the diagnosis of this disease the merits of these methods are discussed in the light of 2 cases of adrenal tuberculosis, followed by a review of the literature. Adrenal calcification is the most significant, although not specific sign of adrenal insufficiency due to tuberculosis. Computed tomography has proven to be the method of choice in the non-invasive diagnosis of tuberculous adrenalopathy and in the monitoring of tuberculostatic treatment in this disease. Sonography is helpful as a preliminary investigation. (Author)

In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

    Full Text Available Background. Gestational choriocarcinoma (GC is a recognized clinicopathological subtype of gestational trophoblastic neoplasia that usually metastasizes hematogenously to highly vascular organs like the lung, liver, and brain. However, orbital metastasis to the choroid and lacrimal gland is a rare occurrence. Case Presentation. A 21-year-old female presented with headache and left orbital swelling one year after resection of a complete hydatidiform mole followed by adjuvant methotrexate chemotherapy. A metastatic imaging screening revealed multiple metastases in the lungs, brain, and adrenal gland, in addition to the choroid and lacrimal gland. Based on her modified WHO risk factors scoring she was started on chemotherapy and whole brain radiotherapy, which resulted in a complete response. At two-year follow-up, serum b-HCG level was with normal limits; imaging surveillance was uneventful. Conclusion. We present the first case of lacrimal gland metastasis in a young girl from GC relapse.

    Full Text Available Abstract Introduction Autopsy series have shown that metastasis to the thyroid gland has occurred in up to 24% of patients who have died of cancer. Neuroendocrine tumors may metastasize to thyroid gland. Case presentations Case 1 was a 17-year-old Turkish woman who was referred from our Endocrinology Department for a thyroidectomy for treatment of neuroendocrine tumor metastasis. She was treated with a bilateral total thyroidectomy. Histopathological examination results were consistent with a neuroendocrine tumor; neoplastic cells showed strong immunoreactivity to chromogranin A and synaptophysin, but the immunohistochemical profile was inconsistent with medullary thyroid carcinoma in that the tumor was negative for calcitonin, carcinoembryonic antigen, and thyroid transcription factor-1. Case 2 was a 54-year-old Turkish woman who presented with a 3-cm nodule on her right thyroid lobe. She had undergone surgery for a right lung mass four years previously. After a right pneumonectomy, thymectomy and lymph node dissection, a typical carcinoid tumor was diagnosed. Under ultrasonographic guidance, fine needle aspiration biopsy of her right thyroid pole nodule was performed and the biopsy was compatible with a neuroendocrine tumor metastasis. She was treated with a bilateral total thyroidectomy. Histopathological examination indicated three nodular lesions, 5 cm and 0.4 cm in diameter in her right lobe and 0.1 cm in diameter in her left lobe. The tumors were consistent with a neuroendocrine phenotype, showing strong immunoreactivity to chromogranin A and synaptophysin. Conclusion Thyroid nodules detected during follow-up of neuroendocrine tumor patients should be thoroughly investigated. A fine needle aspiration biopsy of the thyroid confirms the diagnosis in most cases and leads to appropriate management of those patients and may prevent unnecessary treatment approaches.

    Full Text Available Addisonian crisis as a first manifestation of metastatic disease secondary to cancer is uncommon. We report a 63-year-old man with a history of one year of fatigue, weakness, weight loss and repeated symptomatic hypoglycemia. The cortisol stimulation test with ACTH confirmed primary adrenal insufficiency. While receiving adequate treatment with oral hydrocortisone, he presented an adrenal crisis that was treated properly. A CT scan of the lung demonstrated a nodule in the upper right lobe and bilateral adrenal tumors. The biopsy of the lesion revealed a lung adenocarcinoma. The staging with positron emission tomography using 18 fluoroglucose (PET/CT18F- FDG showed hypermetabolic uptake in the primary lung tumor and in both adrenal glands, suggesting metastatic implants.

  11. Concomitant bilateral testicular epidermoid cysts

    International Nuclear Information System (INIS)

    Epidermoid cyst of the testis is a rare benign germ tumor, comprising 1-2% of all resected benign testicular masses. Approximately 300 cases have been reported to date. Unilateral involvement has often been reported in the English literature. However, bilateral occurrence is very rare and to the best of our knowledge, there only 3 previous reports of bilateral testicular epidermoid cysts. The fact that they are completely benign makes them amenable to treatment by local excision, thereby saving patient from orchidectomy. Recognition of their characteristic ulatrsonographic features is very important to avoid unnecessary intervention. We present here, a case of bilateral epidermoid cyst in which characteristic ultrasound (US) findings allowed testis-sparing enucleation instead of radical orchiectomy. (author)

  17. Adrenal scintigraphy with 131I-19 iodocholesterol. Interest in Cushing syndrome investigation

    International Nuclear Information System (INIS)

    A review of the physico-chemical properties of 131I-19-iodocholesterol is followed by a study of its metabolism in both animals and man, giving for the latter the doses delivered to different organs and especially to the gonads. The exploration technique is then described. Scintigraphic examinations are performed on the 3rd day, the 8th day and sometimes the 15th day after injection. However the uptake rate at the adrenal gland depends essentially on the causes of the illness affecting the suprarenal. In Cushing's syndrome the uptake rate is relatively fast and the 1st scintigraphic examination must therefore be carried out earlier (48 hours after injection). The value of isotopic exploration in the etiological evaluation of hypercortisolism is shown to be chiefly morphological, the scintigraphic image serving as a guide to etiological diagnosis. If too adrenal glands are visible this is a sign of bilateral suprerenal hyperplasia. Only one gland clearly visible indicates an adenoma, with functional hypoplasia of the contralateral gland. On the other hand an absence of fixation in the presence of a certain Cushing syndrome would point to malignant cortical carcinoma

    Serous adenocarcinoma of the ovary rarely can present with solitary solid -cystic cerebellar metastasis, mimicking pilocytic astrocytoma. A middle aged women, who underwent total abdominal hysterectomy with bilateral salpingoopherectomy and adjuvant chemotherapy for ovarian adenocarcinoma, presented to us with the history of headache, vomiting, and imbalance. Contrast enhanced magnetic resonance imaging (MRI) showed solitary cerebellar, solid cystic lesion with cyst lining and solid portion enhancing on contrast which was mimicking pilocytic astrocytoma and there was no perilesional edema. Gross total excision of the cerebellar lesion was done followed by resolution of her symptoms. Histopathology showed metastatic adenocarcinoma consistent with the primary ovarian carcinoma. In patients of ovarian carcinoma, presenting with features of raised intracranial pressureICP] thorough investigations must be done to rule out metastasis. Solitary metastasis of the cerebellum because of ovarian carcinoma may mimic pilocytic astrocytoma. PMID:23293670

  20. Microenvironment Determinants of Brain Metastasis

    2011-02-01

    Full Text Available Abstract Metastasis accounts for 90% of cancer-related mortality. Brain metastases generally present during the late stages in the natural history of cancer progression. Recent advances in cancer treatment and management have resulted in better control of systemic disease metastatic to organs other than the brain and improved patient survival. However, patients who experience recurrent disease manifest an increasing number of brain metastases, which are usually refractory to therapies. To meet the new challenges of controlling brain metastasis, the research community has been tackling the problem with novel experimental models and research tools, which have led to an improved understanding of brain metastasis. The time-tested "seed-and-soil" hypothesis of metastasis indicates that successful outgrowth of deadly metastatic tumors depends on permissible interactions between the metastatic cancer cells and the site-specific microenvironment in the host organs. Consistently, recent studies indicate that the brain, the major component of the central nervous system, has unique physiological features that can determine the outcome of metastatic tumor growth. The current review summarizes recent discoveries on these tumor-brain interactions, and the potential clinical implications these novel findings could have for the better treatment of patients with brain metastasis.

    Full Text Available Background: Primary synchronous bilateral breast cancer (PSBBC is a rare clinical entity. The reported incidence ranges between 0.3% and 12%. There are several controversial issues regarding PSBBC pertaining to the diagnostic criteria, nomenclature, and management policies. Materials and Methods: Fourteen cases of PSBBC treated between 2001 to 2010 at our institute were retrospectively analysed in regards to demographic data, management and follow up. Results: PSBBC constituted 0.19% of total breast cancer patients at our institute. Age ranged from 28 to 78 years. PSBBC were detected by clinical examination in eight cases and by mammography in six cases. Twelve patients underwent bilateral modified radical mastectomy, one had unilateral mastectomy on one side and breast conservation on the other side and one patient has bilateral breast conservation. Majority of patients belonged to stage 2 and stage 3. All patients were found to have invasive ductal carcinoma. Five cases were ER/PR positive and 8 patients were triple hormone receptor negative. Eight patients received unilateral and six received bilateral adjuvant radiotherapy. Nine patients received adjuvant chemotherapy. 5 patients received adjuvant hormonal therapy. Median follow up of patients was 15.4 months. Conclusion: PSBBC is a rare event warranting awareness and screening of the contralateral breast in patients with unilateral breast cancer. These patients require individualized treatment planning based on the tumor factors of the index lesion. Further multi institutional prospective studies are needed for adequate understanding of management of PSBBC.

  3. Pitfalls of adrenal imaging with chemical shift MRI

    International Nuclear Information System (INIS)

    Chemical shift (CS) MRI of the adrenal glands exploits the different precessional frequencies of fat and water protons to differentiate the intracytoplasmic lipid-containing adrenal adenoma from other adrenal lesions. The purpose of this review is to illustrate both technical and interpretive pitfalls of adrenal imaging with CS MRI and emphasize the importance of adherence to strict technical specifications and errors that may occur when other imaging features and clinical factors are not incorporated into the diagnosis. When performed properly, the specificity of CS MRI for the diagnosis of adrenal adenoma is over 90%. Sampling the in-phase and opposed-phase echoes in the correct order and during the same breath-hold are essential requirements, and using the first echo pair is preferred, if possible. CS MRI characterizes more adrenal adenomas then unenhanced CT but may be non-diagnostic in a proportion of lipid-poor adenomas; CT washout studies may be able to diagnose these lipid-poor adenomas. Other primary and secondary adrenal tumours and supra-renal disease entities may contain lipid or gross fat and mimic adenoma or myelolipoma. Heterogeneity within an adrenal lesion that contains intracytoplasmic lipid could be due to myelolipoma, lipomatous metaplasia of adenoma, or collision tumour. Correlation with previous imaging, other imaging features, clinical history, and laboratory investigations can minimize interpretive errors

    Objective To explore expression of endogenous ouabain(EO) in multiple adrenal tumors.Methods Thirty-one cases of adrenal tumors and 6 cases of healthy adrenal tissues were selected. The expression of EO in the adrenal tiss ue was detected with immunohistochemical streptavidin peroxadase conjugated(SP) method.Results Most of EO positive products were localized in cy toplasm of the zona reticularis of human adrenal cortex, and positive products s howed to be fine granular. There was no positive signal in the medulla. EO showe d on diffused positive in patients with pheochromocytoma accompanied high blood pressure[SBP:(165.22±7.61) mmHg, DBP:(105.52±4.26) mmHg], but there were neg ative in ones with normative blood pressure[SBP:(118.52±4.58) mmHg, DBP:(83±3.60) m mHg]. The expression of EO was positive in all adrenocortical hyperplasic, aden oma an d carcinoma, no matter its high or normative blood pressure. The degree of expre ssion of EO in adrenal tissues was related to the level of BP.Conclusion Expression of endogenous ouabain(EO) in health y adrenal tissue and adrenal tumors was a valuable morphological and pathophysio logical clue for the research on ouabain.

  6. Clinical experience with 75Se selenomethylcholesterol adrenal imaging

    International Nuclear Information System (INIS)

    The results of quantitative adrenal imaging using 75Se selenomethylcholesterol in sixty-two subjects are analysed. The adrenal area was localized by a renal scan, lateral views of which enabled adrenal depth to be estimated. The first nineteen cases were scanned with a rectilinear scanner and the remaining forty-three cases imaged with a gamma camera. Quantitation of adrenal uptake was performed on computer-stored static images obtained 7 and 14 days post-injection of 75Se selenomethylcholesterol (3 and 6 days in the first ten cases studied). Normal uptake was found to be 0.07-0.30% of the administered dose. Overall predictive accuracy of the type of adrenal disorder of thirty-two patients with Cushing's syndrome was 90.6%. Overall predictive accuracy of the cause of Conn's syndrome in twenty-two cases was 86.4%. The mean uptake in the normal adrenal in cases of unilateral adenoma was 0.19% (range 0.07-0.30%). Causes of unsatisfactory adrenal imaging are examined. The procedure is recommended as the localizing and lateralizing technique of choice in Cushing's syndrome except where due to adrenal carcinoma, and as an important non-invasive technique in Conn's syndrome for the lateralization of adenoma.

  9. Incidence and Cause of Hypertension During Adrenal Radiofrequency Ablation

    International Nuclear Information System (INIS)

    Purpose: To evaluate the incidence and cause of hypertension prospectively during adrenal radiofrequency ablation (RFA). Methods: For this study, approved by our institutional review board, written informed consent was obtained from all patients. Patients who received RFA for adrenal tumors (adrenal ablation) and other abdominal tumors (nonadrenal ablation) were included in this prospective study. Blood pressure was monitored during RFA. Serum adrenal hormone levels including epinephrine, norepinephrine, dopamine, and cortisol levels were measured before and during RFA. The respective incidences of procedural hypertension (systolic blood pressure >200 mmHg) of the two patient groups were compared. Factors correlating with procedural systolic blood pressure were evaluated by regression analysis.ResultsNine patients underwent adrenal RFA and another 9 patients liver (n = 5) and renal (n = 4) RFA. Asymptomatic procedural hypertension that returned to the baseline by injecting calcium blocker was found in 7 (38.9%) of 18 patients. The incidence of procedural hypertension was significantly higher in the adrenal ablation group (66.7%, 6/9) than in the nonadrenal ablation group (11.1%, 1/9, P 2 = 0.68, P 2 = 0.72, P < 0.0001) levels during RFA. The other adrenal hormones did not show correlation with procedural systolic blood pressure. Conclusion: Hypertension occurs frequently during adrenal RFA because of the release of catecholamine.

    Monticone, Silvia; Viola, Andrea; Rossato, Denis; Veglio, Franco; Reincke, Martin; Gomez-Sanchez, Celso; Mulatero, Paolo

    2015-04-01

    Primary aldosteronism comprises subtypes that need different therapeutic strategies. Adrenal vein sampling is recognised by Endocrine Society guidelines as the only reliable way to correctly diagnose the subtype of primary aldosteronism. Unfortunately, despite being the gold-standard procedure, no standardised procedure exists either in terms of performance or interpretation criteria. In this Personal View, we address several questions that clinicians are presented with when considering adrenal vein sampling. For each of these questions we provide responses based on the available evidence, and opinions based on our experience. In particular, we discuss the most appropriate way to prepare the patient, whether adrenal vein sampling can be avoided for some subgroups of patients, the use of ACTH (1-24) during the procedure, the most appropriate criteria for interpretation of adrenal vein cannulation and lateralisation, the use of contralateral suppression, and strategies to improve success rates of adrenal vein sampling in centres with little experience. PMID:24831990

  12. The place of imaging in exploration of the adrenal glands

    International Nuclear Information System (INIS)

    Currently, the major method of adrenal gland imaging is computed tomography. This method allows demonstration of normal adrenals and the diagnosis of adrenal masses (if these are greater than 1 cm in diameter). The examination should be directed by clinical signs and known laboratory investigations. Computed tomography is therefore the first line investigation to perform. Certain lesions may be better demonstrated by other methods: MRI and MIBG scintigraphy offer a greater specificity in the investigation of pheochromocytomas. In addition, scintigraphy can identify possible ectopic tumours or recurrences. - Selective catheterisation of the adrenal veins allows aldosterone and cortisone secretions to be assayed. There remains the problem of the incidental finding of adrenal masses in either an asymptomatic patient or in the context of investigation of spread of a known cancer. These lesions may benefit from diagnostic percutaneous guided biopsy

    Contrast-enhanced ultrasonography is useful in differentiating adrenal gland adenomas from nonadenomatous lesions in human patients. The purposes of this study were to evaluate the feasibility and to describe contrast-enhanced ultrasonography of the normal canine adrenal gland. Six healthy female Beagles were injected with an intravenous bolus of a lipid-shelled contrast agent (SonoVue(®) ). The aorta enhanced immediately followed by the renal artery and then the adrenal gland. Adrenal gland enhancement was uniform, centrifugal, and rapid from the medulla to the cortex. When maximum enhancement was reached, a gradual homogeneous decrease in echogenicity of the adrenal gland began and simultaneously enhancement of the phrenicoabdominal vessels was observed. While enhancement kept decreasing in the adrenal parenchyma, the renal vein, caudal vena cava, and phrenicoabdominal vein were characterized by persistent enhancement until the end of the study. A second contrast enhancement was observed, corresponding to the refilling time. Objective measurements were performed storing the images for off-line image analysis using Image J (ImageJ(©) ). The shape of the time-intensity curve reflecting adrenal perfusion was similar in all dogs. Ratios of the values of the cortex and the medulla to the values of the renal artery were characterized by significant differences from initial upslope to the peak allowing differentiation between the cortex and the medulla for both adrenal glands only in this time period. Contrast-enhanced ultrasonography of the adrenal glands is feasible in dogs and the optimal time for adrenal imaging is between 5 and 90 s after injection. PMID:21521396

  1. Pulmonary Metastasis from Pseudomyxoma Peritonei

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Pseudomyxoma peritonei (PMP is a rare clinical condition, where copious mucinous ascites accumulate in the peritoneal cavity due to dissemination of mucin-producing tumor. Because of this disseminating, yet nonmetastasizing, behavior, PMP attracts much interest from surgical oncologists in that aggressive locoregional therapy can give the opportunity of long survival and even cure. Although extra-abdominal metastasis is exceptionally rare, the lung is the most likely site in such a case. In this paper, the clinical findings and treatment of eleven cases with pulmonary metastasis from PMP were reviewed, including ten cases in the literature and one case which we experienced. The clinical features of PMP cases with pulmonary metastasis were similar to cases without pulmonary metastasis. The histological type was low-grade mucinous neoplasm in most cases. Pulmonary lesions were resected in seven cases in which abdominal lesions were controlled by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy or another therapeutic modality. Disease-free state was maintained in five cases at the end of the follow-up period. However, it should be noted that rapid progression after resection was seen in two cases, suggesting that biological features may have changed by surgical intervention.

    Full Text Available Gallbladder cancer is generally diagnosed at an advanced stage. The liver is the mostcommonly invaded organ by direct extension and/or metastasis, followed by regional lymphnodes. Oral soft tissue metastasis is extremely unusual. This report describes the case of a62-year-old woman diagnosed with advanced metastatic gallbladder cancer, who initiallypresented with abdominal pain. Diagnosis of gallbladder cancer was made about 3 monthsafter her symptoms developed, when a laparoscopic cholecystectomy was performedbecause of the suspicion of gallstones. Liver metastasis was also discovered during surgery.A postoperative investigation revealed additional lung and bone metastases. A visible leftgingival tumor was found on physical examination and was confirmed as gallbladder cancermetastasis by compatible histopathology 1 month after surgery. The patient responded poorlyto chemotherapy and unfortunately died 5 months after the diagnosis. The clinical presentationof gallbladder cancer was relatively typical, apart from the unusual gingival metastasis.The medical literature contains quite a few examples of metastatic lesions locatedstrictly in the oral soft tissue, however no case of gallbladder cancer metastasizing to theoral soft tissue has been previously reported.

    We study the determinants of China’s bilateral local currency swap lines that were established since the recent global finance crisis. It is found that economic factors, political considerations, and institutional characteristics including trade intensity, economic size, strategic partnership, free trade agreement, corruption, and stability affect the decision of signing a swap line agreement. Once a swap line agreement decision is made, the size of the swap line is then mainly affected by tr...

    We analyse how equilibrium locations in location-price games à la Hotelling are affected when firms acquire inputs through bilateral monopoly relations with suppliers. Assuming a duopoly downstream market, we consider the case of two independent input suppliers bargaining with both downstream firms. We find that the presence of input suppliers changes the locational incentives of downstream firms in several ways, compared with the case of exogenous production costs. Bargaining induces downstr...

  9. Adrenal gland infection by serotype 5 adenovirus requires coagulation factors.

    Directory of Open Access Journals (Sweden)

    Lucile Tran

    Full Text Available Recombinant, replication-deficient serotype 5 adenovirus infects the liver upon in vivo, systemic injection in rodents. This infection requires the binding of factor X to the capsid of this adenovirus. Another organ, the adrenal gland is also infected upon systemic administration of Ad, however, whether this infection is dependent on the cocksackie adenovirus receptor (CAR or depends on the binding of factor X to the viral capsid remained to be determined. In the present work, we have used a pharmacological agent (warfarin as well as recombinant adenoviruses lacking the binding site of Factor X to elucidate this mechanism in mice. We demonstrate that, as observed in the liver, adenovirus infection of the adrenal glands in vivo requires Factor X. Considering that the level of transduction of the adrenal glands is well-below that of the liver and that capsid-modified adenoviruses are unlikely to selectively infect the adrenal glands, we have used single-photon emission computed tomography (SPECT imaging of gene expression to determine whether local virus administration (direct injection in the kidney could increase gene transfer to the adrenal glands. We demonstrate that direct injection of the virus in the kidney increases gene transfer in the adrenal gland but liver transduction remains important. These observations strongly suggest that serotype 5 adenovirus uses a similar mechanism to infect liver and adrenal gland and that selective transgene expression in the latter is more likely to be achieved through transcriptional targeting.

    The brain and adrenal are critical control centers that maintain body homeostasis under basal and stress conditions, and orchestrate the body's response to stress. It is noteworthy that patients with stress-related disorders exhibit increased vulnerability to mental illness, even years after the stress experience, which is able to generate long-term changes in the brain's architecture and function. High levels of glucocorticoids produced by the adrenal cortex of the stressed subject reduce neurogenesis, which contributes to the development of depression. In support of the brain-adrenal connection in stress, many (but not all) depressed patients have alterations in the components of the limbic-hypothalamic-pituitary-adrenal (LHPA) axis, with enlarged adrenal cortex and increased glucocorticoid levels. Other psychiatric disorders, such as post-traumatic stress disorder, bipolar disorder and depression, are also associated with abnormalities in hippocampal volume and hippocampal function. In addition, hippocampal lesions impair the regulation of the LHPA axis in stress response. Our knowledge of the functional connection between stress, brain function and adrenal has been further expanded by two recent, independent papers that elucidate the effects of stress on brain and adrenal stem cells, showing similarities in the way that the progenitor populations of these organs behave under stress, and shedding more light into the potential cellular and molecular mechanisms involved in the adaptation of tissues to stress.

  11. Adrenal pseudomasses due to varices: angiographic-CT-MRI-pathologic correlations

    International Nuclear Information System (INIS)

    Periadrenal and adrenal portosystemic collaterals are a recently reported cause of adrenal pseudotumor on computed tomography (CT). Nine patients with this left adrenal pseudotumor illustrate its typical position and appearance on CT, angiography, CT-angiography, and magnetic resonance imaging (MRI). The anatomic basis for variceal adrenal pseudotumors is the left inferior phrenic vein, which passes immediately anterior to the left adrenal gland and which serves as a collateral pathway from splenic to left renal vein in portal hypertension. Thus, unlike previously described adrenal pseudotumors, these venous collaterals are not anatomically distinguishable from the adrenal gland on CT. Bolus dynamic CT is usually diagnostic, but in equivocal cases, MRI may prove useful

    Full Text Available Testicular adrenal rest tumors (TARTs are considered to be formed from aberrant adrenal tissue that has become hyperplastic because of elevated adrenocorticotropic hormone (ACTH in male patients with congenital adrenal hyperplasia (CAH. A 6-year-old boy presented with testicular enlargement and pubic hair. He was diagnosed with CAH complicated by precocious puberty. However, he was not followed-up. At the age of 17, he visited the outpatient clinic because of testicular enlargement and short stature. His right and left testicles were 10×6 cm and 7.5×4.5 cm, respectively. His height was 155.1 cm (standard deviation score [SDS], -2.90. The diagnosis of CAH due to 21 hydroxylase deficiency was confirmed by mutation analysis of CYP21A2. Histological examination of the testes showed large, polygonal, eosinophilic cells with round nuclei and prominent nucleoli, which were suggestive of TARTs. He was treated with dexamethasone for 3 weeks and tumors regressed. Subsequently, dexamethasone was replaced by prednisolone and 9?#7014;ludrocortisone; thereafter, the reduced testis size has been maintained.

    Three cases of adrenal cystic lymphangioma are reported. In 1 patient the lesion was complicated by intracystic haemorrhage. The remaining 2 patients had a hepatic lesion which was treated in the same surgical operation as the adrenal cyst. Ultrasonography and computerized tomography play a major role in the exploration of these cysts. Their unexpected discovery has become more frequent since these methods have multiplied, and this raises therapeutic problems. The nature of adrenal cysts is determined at histology. In asymptomatic cysts percutaneous needle aspiration can only have an indicative value. PMID:8493206

    2012-09-01

    The endocrine disorder adrenal insufficiency includes inadequate production of the steroid hormone cortisol. This results in poor physiological responses to illness, trauma or other stressors and risk of adrenal crisis. Management is based on administration of hydrocortisone. It is important to avoid under- or over-treatment and increase the dosage during times of physiological stress. To reduce morbidity, hospital admissions and mortality, the education and empowerment of parents and carers, and prompt intervention when necessary are essential. A steroid therapy card for adrenal insufficiency containing personal information on a patient\\'s condition was developed for use by families and their specialist centres.

    2013-01-01

    Full Text Available Congenital adrenal hyperplasia (CAH describes a group of autosomal recessive disorders where there is impairment of cortisol biosynthesis. CAH due to 21-hydroxylase deficiency accounts for 95% of cases and shows a wide range of clinical severity. Glucocorticoid and mineralocorticoid replacement therapies are the mainstays of treatment of CAH. The optimal treatment for adults with CAH continues to be a challenge. Important long-term health issues for adults with CAH affect both men and women. These issues may either be due to the disease or to steroid treatment and may affect final height, fertility, cardiometabolic risk, bone metabolism, neuro-cognitive development and the quality-of-life. Patients with CAH should be regularly followed-up from childhood to adulthood by multidisciplinary teams who have knowledge of CAH. Optimal replacement therapy, close clinical and laboratory monitoring, early life-style interventions, early and regular fertility assessment and continuous psychological management are needed to improve outcome.

    Nasopharyngeal carcinoma is the second most common type of malignancy in Southern China. Metastatic sites are usually multifocal and involve the bones, lungs and distant lymph nodes. To date, there have been no studies with regard to nasopharyngeal carcinoma metastasis to the mammary gland. In the current study, the case of a 56-year-old female with nasal obstruction, epitaxis and a bilateral neck mass is presented. Following a series of examinations, the patient was diagnosed with nasopharyngeal carcinoma (cT3N3M0). Subsequently, the patient received radical radiation therapy. After three months, a mass was identified in the left breast, together with enlargement of multiple lymph nodes in the left axilla. The patient underwent a mastectomy and pathological examination revealed that the breast mass and axillary lymph node tissues were derived from the nasopharynx. To the best of our knowledge, this is the first report of a nasopharyngeal carcinoma that metastasized to the mammary gland. PMID:25435974

  18. Clinicopathologic characteristics and prognostic factors of 63 gastric cancer patients with metachronous ovarian metastasis

    International Nuclear Information System (INIS)

    This study aims to explore the clinicopathologic characteristics and prognostic factors of gastric cancer patients with metachronous ovarian metastasis. Clinicopathologic data were collected from 63 post-operative gastric cancer patients with metachronous ovarian metastasis. The patients were admitted to the Cancer Institute and Hospital, Chinese Academy of Medical Science and Peking Union Medical College between January 1999 and December 2011. A log-rank test was conducted for survival analysis. Possible prognostic factors that affect survival were examined by univariate analysis. A Cox regression model was used for multivariate analysis. The incidence of ovarian metastasis was 3.4% with a mean age of 45 years. Up to 65.1% of the patients were pre-menopausal. The mean interval between ovarian metastasis and primary cancer was 16 months. Lowly differentiated carcinoma ranked first in the primary gastric cancers. The majority of lesions occurred in the serous membrane (87.3%). The metastatic sites included N2-3 lymph nodes (68.3%), bilateral ovaries (85.7%), and peritoneal membrane (73%). Total resection of metastatic sites was performed (31.7%). The overall median survival was 13.6 months, whereas the overall 1-, 2-, and 3-year survival rates were 52.5%, 22.0%, and 9.8%, respectively. The 5-year survival rate was zero. Univariate analysis showed that the patient prognosis was correlated with metastatic peritoneal seeding, vascular tumor embolus, range of lesion excision, and mode of comprehensive treatment with adjuvant chemotherapy (P<0.05). Multivariate analysis indicated that metastatic peritoneal seeding was an independent prognostic factor for gastric cancer patients with ovarian metastasis (P<0.01). Effective control of peritoneal seeding—induced metastasis is important for improving the prognosis of gastric cancer patients with ovarian metastasis

    Objective: To study the clinical pathological characteristics of ovarian metastasis of endometrial carcinoma and the factors affecting prognosis. Methods: Retrospective analysis was made to the clinical pathological outcome of endometrial carcinoma patients receiving surgical treatment in our hospital from January 1990 to December 2002. Results:Among the 191 cases of endometrial carcinoma patients, 17 cases (8.9%) had ovarian metastasis and young patients were more likely to have ovarian metastasis. The multiple factor analysis showed that the independent risk factors of ovarian metastasis in endometrial carcinoma included the depth of myometrial invasion, lymph node metastasis and pathological types. Conclusion: Ovarian metastasis in patients with endometrial carcinoma is associated with poor prognosis, the depth of myometrial invasion, lymph node metastasis and histologic types are independent risk factors affecting the prognosis. For young patients at early stage of the disease, it should be prudent as to whether to retain the ovary.

    Congenital adrenal hyperplasia (CAH) is an autossomic recessive disorder caused by impaired steroidogenesis. Patients with CAH may present adrenal insufficiency with or without salt-wasting, as well as various degrees of virilization and fertility impairment, carrying a high incidence of testicular adrenal rest tumors and increased incidence of adrenal tumors. The diagnosis of CAH is made based on the adrenocortical profile hormonal evaluation and genotyping, in selected cases. Follow-up is mainly based on hormonal and clinical evaluation. Utility of imaging in this clinical setting may be helpful for the diagnosis, management, and follow-up of the patients, although recommendations according to most guidelines are weak when present. Thus, the authors aimed to conduct a narrative synthesis of how imaging can help in the management of patients with CAH, especially focused on genitography, ultrasonography, computed tomography, and magnetic resonance imaging.

    Plasma corticosterone and ACTH concentrations were determined in neonatal rats 1, 7, 14, and 21 days old, under a variety of experimental conditions, to obtain more information on the postnatal development of the rat hypothalamo-adrenal (HHA) axis. The results indicate that: (1) there is a diminution followed by an increase in responsiveness of the adrenal gland, but the pituitary response to direct hormonal stimulation is unchanged during the first three postnatal weeks; (2) continued stimulation of the adrenal by ACTH or of the central nervous system (CNS) or hypothalamus by corticosterone is necessary during early postnatal development to allow normal maturation of the HHA axis; and (3) feedback inhibition is operative by birth, at least to a moderate degree. Taken together, the studies suggest that both the adrenal and pituitary glands are potentially functional at birth, but that the hypothalamic and CNS mediators of the stress response are not mature until at least the second or third postnatal week.

    Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from severe or treatment-resistant major depressive disorder (MDD). Unfortunately its underlying neurobiological mechanisms are still unclear. One line of evidence indicates that the seizures produced by ECT induce or stimulate neuroplasticity effects. Although these seizures also affect the cortex, the effect of ECT on cortical thickness is not investigated until now. We acquired structural magnetic resonance imaging data in 19 treatment-resistant MDD patients before and after a bilateral ECT course, and 16 healthy controls at 2 time points, and compared changes in cortical thickness between the groups. Our results reveal that ECT induces significant, bilateral increases in cortical thickness, including the temporal pole, inferior and middle temporal cortex and the insula. The pattern of increased cortical thickness was predominant in regions that are associated with seizure onset in ECT. Post hoc analyses showed that the increase in thickness of the insular cortex was larger in responders than in non-responders, which may point to a specific relationship of this region with treatment effects of ECT.

    2009-01-01

    Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it′s management both at the time of cleft lip repair

    Adrenal lymphangiomas, also known as cystic adrenal lymphangiomas, are rare, benign vascular lesions that usually remain asymptomatic throughout life. Although previously adrenal lymphangioma lesions were primarily found at autopsy, they are currently detected during imaging work-up for unrelated causes and are likely to imitate other adrenocortical or adrenal medullary neoplasms. We aimed to retrospectively review all adrenal lymphangioma cases at our hospital and further document their lymphatic origin by immunohistochemical staining. A search of surgical pathology records (1984-2008) was conducted. All hematoxylin and eosin sections were retrieved from archives and reviewed by 2 pathologists in the study. Clinical information was gathered from electronic medical records. Representative paraffin-embedded sections from each case were selected for immunohistochemical analysis using monoclonal antibodies D2-40 and AE1/AE3. A total of 9 adrenal lymphangioma cases were identified (6 women and 3 men). All 9 patients were adults at time of diagnosis with a mean age of 42 years (range, 28-56 years). There were 7 white patients, 1 African American patient, and 1 Asian patient. The average size of an adrenal lymphangioma lesion was 4.9 cm (range, 2.0-13.5 cm). Adrenal lymphangioma was twice more frequently located on the right side (6 right-sided and 3 left-sided). Clinically, 4 (44%) of the 9 lesions presented with abdominal, flank, or back pain. One lymphangioma was found during work-up for labile hypertension. The remaining 4 lesions (44%) were asymptomatic and incidentally found during imaging studies for unrelated causes. Surgical removal was achieved by total adrenalectomy in 8 of the 9 lesions and by partial adrenalectomy in the remaining case. No evidence of recurrence or development of a contralateral lesion was encountered in any of the patients. Histologically, our adrenal lymphangiomas showed a typical multicystic architecture with dilated spaces lined by

    Previously we observed that neural cell adhesion molecule (NCAM) deficiency in beta tumor cells facilitates metastasis into distant organs and local lymph nodes. Here, we show that NCAM-deficient beta cell tumors grew leaky blood vessels with perturbed pericyte-endothelial cell-cell interactions...... and deficient perivascular deposition of ECM components. Conversely, tumor cell expression of NCAM in a fibrosarcoma model (T241) improved pericyte recruitment and increased perivascular deposition of ECM molecules. Together, these findings suggest that NCAM may limit tumor cell metastasis by...... stabilizing the microvessel wall. To directly address whether pericyte dysfunction increases the metastatic potential of solid tumors, we studied beta cell tumorigenesis in primary pericyte-deficient Pdgfb(ret/ret) mice. This resulted in beta tumor cell metastases in distant organs and local lymph nodes...

    Macrodontia is a rare dental anomaly that refers to teeth that appear larger than normal. Generalised macrodontia can be associated with certain medical conditions and syndromes. This case report presents clinical and radiographic findings of isolated bilateral macrodontia in a 14-year-old child. The patient was referred to the clinic with local crowding of maxillary and mandibular teeth. Radiographic findings revealed the presence of impacted macrodont mandibular second premolar on one side and erupted macrodontic premolar on the other side and their distinct morphological appearance, characterized by large, multitubercular, and molariform crowns and tapering, single roots.

    2016-07-01

    We have noted an increasing number of cases of enlarged adrenal glands where the underlying diagnosis was masked by a diffusely hemorrhagic process. We identified from our database 59 cases (32 consults, 27 routine) of adrenal glands with diffuse (>25%) hemorrhage received between 2000 and 2014. Fifty-three adrenalectomies and 6 biopsies were identified. The diagnoses after central review were 41 adrenocortical adenomas, 1 nodular adrenocortical hyperplasia with associated myelolipoma, 1 benign adrenocortical cyst, and 10 nonneoplastic adrenal glands with hemorrhage. A definitive diagnosis for the 6 biopsies was precluded by the sample size. The adrenocortical adenomas (size, 1-13 cm; 25%-95% hemorrhage) showed clear cell change in the neoplastic area (10%-80% of the tumor), 19 showed focal calcification (1 with ossification), 11 showed areas of papillary endothelial hyperplasia, 10 showed scattered lymphoplasmacytic inflammation, 6 showed benign cortical tissue extending beyond the adrenal capsule into soft tissue, 1 showed necrosis in the form of ghost cells, 2 showed lipomatous change, and 6 were associated with incidental benign lesions (1 cortical cyst, 1 schwannoma, and 4 myelolipomas). Twenty-four of the adrenocortical adenomas were consults where the referring pathologist had trouble classifying the lesion. Of the 10 nonneoplastic adrenals (4.5-22 cm; 40%-80% hemorrhage), 2 were consults. In summary, pathologists have difficulties recognizing adrenocortical adenomas in the setting of a massively enlarged and hemorrhagic adrenal gland. Although there is a correlation between adrenocortical malignancy and size, hemorrhage into nonmalignant adrenal glands can result in markedly enlarged adrenals. PMID:27001431

    Full Text Available Background: The endocrine adrenal gland has 3 zones comprised of the cortex and medulla.The character of multi-hormonal expression results in multiple clinicalmanifestations. To define the clinical characteristics of adrenal tumors inTaiwan, we reviewed 336 pathologically proven adrenal tumors at ChangGung Memorial Hospital in Linkou.Methods: We retrospectively analyzed 258 pathologically proven adrenal tumors withsufficient data treated from 1983 to 2000. Among them, 174 (67% werefunctional and 84 (33% were nonfunctional. The diagnosis was based onclinical features, hormonal status, imaging studies, and pathology.Results: Of the 258 patients, 161 were women (mean age, 38.5¡ 15.4; range, 1-75years and 97 men (mean age, 41.6¡ 17.8; range, 1-81 years. The prevalenceof cortical tumors was much higher in females than in males. Fifty-twopercent of patients with an adrenal tumor were diagnosed at an age between30 and 50 years. Incidentalomas (N=84 accounted for about 1/3 of totaltumor cases. Of the 46 cases proven to be malignant, 40 (87% were foundincidentally. All malignant tumors had a diameter of greater than 3 cm.Postoperative adrenal insufficiency was present in 18% of cases, and overallmortality in this study was 0.4%.Conclusions: In our series, adrenal incidentalomas corresponded to about 1/3 of adrenaltumors and accounted for 87% of malignancies. It is mandatory to increasemedical attention for incidentally found adrenal masses in Taiwan. Thoseincidentalomas with a diameter of more than 3 cm should undergo a pathologicalexamination.

    Spontaneous adrenal haemorrhage (SAH) is a rare event in the general population, estimated to be around 0.3-1.8%. The exact incidence in pregnancy is unknown but rare. Most cases of SAH at or near term have presented with massive haemorrhage and haemodynamic instability, requiring emergency caesarean delivery or intrauterine fetal death. This is the first reported case of a successful vaginal delivery after acute, spontaneous, left adrenal haemorrhage at term. PMID:27190116

    Penile cancer as primary disease is relatively rare in developed countries. The penis is a rare site of metastases in spite of its rich vascularization. Approximately 500 cases have been reported in the literature; almost 70% of primary lesions are of pelvic origin (from genitourinary or recto-sigmoid primary tumors). We describe a case of penile metastasis from lung cancer. The rarity of the event prompted us to also explore related reviews and discuss the incidence, physiopathology, diagnos...

  3. Raman spectroscopy of bone metastasis

    2012-02-01

    Raman spectroscopy of bone has been used to characterize chemical changes occurring in diseases such as osteoporosis, osteoarthritis and osteomyelitis. Metastasis of cancer into bone causes changes to bone quality that are similar to those observed in osteoporosis, such as decreased bone strength, but with an accelerated timeframe. In particular, osteolytic (bone degrading) lesions in bone metastasis have a marked effect on patient quality of life because of increased risk of fractures, pain, and hypercalcemia. We use Raman spectroscopy to examine bone from two different mouse models of osteolytic bone metastasis. Raman spectroscopy measures physicochemical information which cannot be obtained through standard biochemical and histological measurements. This study was reviewed and approved by the University of Michigan University Committee on the Care and Use of Animals. Two mouse models of prostate cancer bone metastasis, RM1 (n=3) and PC3-luc (n=4) were examined. Tibiae were injected with RM1 or PC3-luc cancer cells, while the contralateral tibiae received a placebo injection for use as controls. After 2 weeks of incubation, the mice were sacrificed and the tibiae were examined by Raman microspectroscopy (λ=785 nm). Spectroscopic markers corresponding to mineral stoichiometry, bone mineralization, and mineral crystallinity were compared in spectra from the cancerous and control tibiae. X-ray imaging of the tibia confirmed extensive osteolysis in the RM1 mice, with tumor invasion into adjoining soft tissue and moderate osteolysis in the PC3-luc mice. Raman spectroscopic markers indicate that osteolytic lesions are less mineralized than normal bone tissue, with an altered mineral stoichiometry and crystallinity.

    The main requirement for most metastasis-related applications is the conversion of solid tissue into a single-cell suspension. In theory, this suspension represents the diversity of cells present in the tissue, whether malignant or benign. We have found that cell viability, as measured by trypan blue staining or fluorescence-activated cell sorting (FACS), is critical for evaluating the success of the tissue-dissociation procedure. The recommended goal is at least 70% cell viability. PMID:26832679

    Ocular melanoma is the most common adult primary intraocular tumour. Although helpful for detecting liver lesions. In particular, newer hepatobiliary contrast agents which offer an additional hepatobiliary phase of excretion help in the detection of even tiny liver metastases. Diffusion-weighted imaging is helpful when an i.v. contrast cannot be administered. Treated lesions are also better evaluated with MRI. CT is useful for evaluating lung nodules, large liver metastasis or in patients in whom MRI is medically contraindicated. The disadvantage lies in its inability to detect small liver metastasis and the radiation dose involved. The lesions treated with iodized oil as part of chemoembolization procedures can be followed on CT. Ultrasound can be used only for detecting hepatic metastases. However, it is heavily operator dependent, technically challenging and time consuming especially in patients who are large. Extrahepatic metastasis cannot be seen on ultrasound. Its utility is primarily for the biopsy of liver lesions. Positron emission tomography (PET)-CT can detect lung nodules and large liver lesions but is insensitive to small liver lesions. Moreover, the high radiation dose is a major disadvantage. PMID:27168029

    Objective: To discuss imaging features of the adrenal glands in female pseudohermaphroditism. Methods: 11 cases of female pseudohermaphroditism (8-27 years old) were analyzed retrospectively. Results: In 9 of the 11 patients with female pseudohermaphroditism who did no receive hormone replacement therapy, both internal and external branches of ilateral adrenal glands were found to be thickened, prolonged and twisted, and in 2 of the 9 patients they were found to be macronodularly hyperplasic. In one of the remaining two patients who had received long-term hormone replacement therapy, the adrenal glands were not thickened or twisted, though prolonged; and in the other patient imaging presentation of the adrenal glands was the same as that of those who did not receive hormone replacement therapy, but with co-existence of adrenal myelolipoma. Among the 11 patients agenesis of the uterus and the vagina was found in 4 cases. Conclusion: Female pseudohermaphroditism is a hereditary disease,where hyperplasia of the adrenal glands and agenesis of the uterus and the vagina were secondary. Early detection of these abnormalities by imageology would prove to be helpful in early detection and treatment of the condition.

  9. Chronic ethanol consumption decreases adrenal responsiveness to adrenocorticotropin (ACTH) stimulation

    International Nuclear Information System (INIS)

    Increased alcohol consumption by adolescents and teenagers has heightened awareness of potential endocrine and developmental alterations. The current study was designed to determine whether chronic ethanol intake alters pituitary and adrenal function in the developing rat. One month old male Sprague Dawley rats were administered 6% ethanol in drinking water. After one month of treatment animals were sacrificed and blood, pituitary and adrenal glands collected. Plasma was assayed for ACTH and corticosterone (CS) by radioimmunossay (RIA). Five anterior pituitary glands per group were challenged with 100 μM corticotropin releasing factor (CRF) for 90 min at 37C under 95% air / 5% CO2. Media were analyzed for either ACTH (pituitary) or CS (adrenal) by RIA. Plasma ACTH and CS were unaffected by ethanol consumption. Pituitary response to CRF was not altered by ethanol. The lack of difference in ACTH release was not due to differences in pituitary content of ACTH. However, chronic ethanol consumption did decrease adrenal responsiveness to ACTH stimulation. In vitro corticosterone production was 1.21 ± 0.14 μg/adrenal in controls and 0.70 ± 0.06 μg/adrenal in ethanol consuming rats

    Adrenal glands are paired endocrine glands located over the upper renal poles. Adrenal pathologies have various clinical presentations. They can coexist with the hyperfunction of individual cortical zones or the medulla, insufficiency of the adrenal cortex or retained normal hormonal function. The most common adrenal masses are tumors incidentally detected in imaging examinations (ultrasound, tomography, magnetic resonance imaging), referred to as incidentalomas. They include a range of histopathological entities but cortical adenomas without hormonal hyperfunction are the most common. Each abdominal ultrasound scan of a child or adult should include the assessment of the suprarenal areas. If a previously non-reported, incidental solid focal lesion exceeding 1 cm (incidentaloma) is detected in the suprarenal area, computed tomography or magnetic resonance imaging should be conducted to confirm its presence and for differentiation and the tumor functional status should be determined. Ultrasound imaging is also used to monitor adrenal incidentaloma that is not eligible for a surgery. The paper presents recommendations concerning the performance and assessment of ultrasound examinations of the adrenal glands and their pathological lesions. The article includes new ultrasound techniques, such as tissue harmonic imaging, spatial compound imaging, three-dimensional ultrasound, elastography, contrast-enhanced ultrasound and parametric imaging. The guidelines presented above are consistent with the recommendations of the Polish Ultrasound Society. PMID:26807295

    Background Airway symptoms in asthma are related to decrease of epinephrine secretion, which may be ascribed to elevated nerve growth factor (NGF) in the organism.The aim of this study was to monitor the neuroendocrine alteration in the adrenal medulla of asthmatic rats.Methods Sixteen rats were randomly divided into two groups (n=8), control group and asthma group, and the asthmatic rats were sensitized and challenged with ovalbumin (OVA).The levels of NGF, epinephrine and norepinephrine in serum were detected by enzyme linked immunosorbent assay (ELISA), the NGF expression in adrenal medulla was detected by immunohistochemistry, and the changes in the ultrastructure of the adrenal medulla was observed by electron microscopy.Results The NGF expression was increased in asthmatic rats compared with control rats.Compared with control rats,the results indicated that the epinephrine level was decreased in asthmatic rats, but no significant difference was found in norepinephrine levels.We found more ganglion cells in the adrenal medulla of asthmatic rats than in control rats, with NGF immunostaining mainly located in these ganglion cells.Electron microscopic images showed the density of chromaffin granula decreased and there was shrunken nucleolemma in the adrenal medullary cells of asthmatic rats.Conclusion The innervation of the adrenal medulla is changed in asthmatic rats, and it may contribute to the epinephrine decrease in asthma.

    A case report of a 44 year-old white man admitted to the surgical unit for a bilateral simultaneous pneumothorax is presented. The pneumothorax occurred on day one after a surgical operation for discal hernia; in the past the patient already presented a right spontaneous pneumothorax at 32 years of age and a left pneumothorax at 37 years of age, both treated with a pleural drainage. A thoracic drain was bilaterally positioned with a good result only in the right side. The persistence of the left pneumothorax induced the authors to perform a postero-lateral thoracotomy bullae excision and pleurectomy with a good postoperative course. After a few months a new right pneumothorax occurred and the patient was treated with a right postero-lateral thoracotomy, bullae resection and pleurectomy. On the basis of the case reported, the authors consider the different opportunities in the treatment of spontaneous pneumothorax in relation to the present knowledges and technologies. Surgical procedure is to be preferred in case of persistence of pneumothorax despite a pleural drain and in case of pneumothorax in high risk subjects. Even if thoracoscopy seems to give better results regarding postoperative pain, it is not always possible with such a method to perform a careful pleurectomy neither to obtain it in all cases (above all in secondary pneumothorax). Every case must then be carefully studied to choose the best treatment at present available. PMID:11353349

    Full Text Available Bilateral ovarian tumour in a girl presents the dilemma of conservative versus aggressive approach towards these tumours. When faced with suspicious tumour and complete replacement of the ovaries bilaterally, bilateral oophorectomy is a viable option, though the certain possibility of infertility and lifelong hormonal supplementation is unavoidable. We report a case of bilateral ovarian masses in a young girl, which on histopathological examination showed mature teratoma with aggregates of proliferating capillary and cavernous sized vessels in the tumour wall. Such associations are rare and must be differentiated from a vascular neoplasm.

  20. Effects of experimental varicocele require neither adrenal contribution nor venous reflux

    International Nuclear Information System (INIS)

    Experimental left varicocele (ELV) is known to induce bilateral changes in the rat testis that, where comparisons are possible, are similar to the changes induced by unilateral varicocele in the human. In the present study, we have determined whether or not left adrenal products are important to the changes induced by ELV and whether or not reflux of left renal vein content occurs in the ELV rat. In the first study, testicular blood flow and temperature were studied in control animals and those with ELV, left adrenalectomy (LAX), or ELV + LAX. Control left and right testicular blood flow (33.6 +/- 0.8 and 33.6 +/- 1.5 ml./min./100 gm. tissue respectively) was significantly elevated by ELV (to 39.9 +/- 0.9 and 41.2 +/- 2.7 ml./min./100 gm. tissue, respectively) and the difference between abdominal and testicular temperatures (delta T) was significantly reduced. Control delta T's for right and left testes were 3.2 +/- 0.2C and 3.2 +/- 0.2C, respectively, and right and left delta T's for ELV animals were 2.0 +/- 0.3 degrees C and 2.0 +/- 0.3C, respectively. These blood flow and temperature changes also occurred when ELV animals were subjected to simultaneous LAX. Additionally, when 85Sr-labelled microspheres were infused into the left renal vein, they did not appear in either left or right testes of ELV animals. We conclude that there is no evidence for reflux down the spermatic vein in ELV in rats and adrenal products do not reach the testis via this route after being secreted into the renal vein. We raise the suggestion that the same may be true in the human

  1. Bilateral breast cancer: an evaluation of risk factors and outcome

    International Nuclear Information System (INIS)

    PURPOSE: To compare the outcome of bilateral breast cancer patients to that of patients with unilateral disease. MATERIALS AND METHODS: From 1960-1995, 1254 stage O/I/II/III patients with primary breast cancer were treated by either mastectomy or breast conservation therapy at Thomas Jefferson University Hospital. There were 1141 (91.2%) unilateral, 41 (3.1%) synchronous and 65 (5.7%) metachronous breast cancer patients. Synchronous breast cancers were defined as having a second cancer diagnosis within one year of initial diagnosis. There were 46.2% of patients stage O/I at initial diagnosis, while 68% were stage O/I at subsequent diagnosis. For the metachronous breast cancers, the median interval between first and second diagnosis was 44 months (range of 13-287 months). Median follow-up time was 58 months for the synchronous cancers (15-218 months) and 107 months (21-360 months) for the metachronous cancers. Overall and NED survival, local control and distant metastatic disease rates from the time of the first and second diagnosis were calculated for the synchronous and metachronous patients. These were then compared to the unilateral breast cancer patients and to each other. RESULTS: Synchronous bilateral breast cancer patients had a worse 5 and 10 year NED survival rate (71.2% and 57.0%) compared to the unilateral patients (83.8% and 77.8%) p=.015 and also a higher distant metastasis rate (70.6% and 54.9% vs. 83.5% and 77.8%) (p=.005). Local control and overall survival comparisons were not statistically significant in this group when compared to unilateral patients. There was also no difference noted when comparing metachronous to unilateral patients for the above parameters. When analyzing metachronous and synchronous patients there was a trend revealing a worse NED survival at 5 and 10 years (84.5% and 82.2% vs. 71.2% and 57% p=.07) and a higher metastatic rate (85.9% and 80.9% vs. 70.6% and 54.9% p=.01) in the synchronous group.

    Full Text Available An 11-year-old male German Shepherd dog presented for inappetence and weight loss. Physical examination and initial bloodwork revealed palpable abdominal masses, mild non-regenerative anemia and thrombocytopenia. Survey radiography and abdominal ultrasonography confirmed the presence of bilateral abdominal masses and lymphadenopathy. Contrast-enhanced computed tomography (CT was performed in order to further investigate the origin of the intraabdominal masses, confirming two enlarged cryptorchid testes, one of which had an associated CT whirl sign. Histopathology of the testes and lymph nodes revealed bilateral malignant Sertoli cell tumors and seminomas with lymph node metastasis of both neoplasms. The purpose of this case report is to discuss the benefits of CT in the diagnosis of cryptorchid testes and describe an additional organ that may display CT whirl sign.

    Providing a more comfortable life and a longer survival for pancreatic corpus/tail tumors without metastasis depends on the complete resection. Recently, distal pancreatectomy with celiac axis resection was reported as a feasible and favorable method in selected pancreatic corpus/tail tumors which had invaded the celiac axis. Additional organ resections to the celiac axis were rarely required, and when necessary it was included only a single extra organ resection such as adrenal or intestine. Here, we described a distal pancreatic tumor invading most of the neighboring organs-stomach, celiac axis, left renal vein, left adrenal gland, and splenic flexure were treated by en bloc resection of all these organs. The patient was a 60-year-old man without any severe medical comorbidities. Postoperative course of the patient was uneventful, and he was discharged on postoperative day eight without any complication. Histopathology and stage of the tumor were adenocarcinoma and T4 N1 M0, respectively. Preoperative back pain of the patient was completely relieved in the postoperative period. As a result, celiac axis resection for pancreatic cancer is an extensive surgery, and a combined en masse resection of the invaded neighboring organs is a more extensive surgery than the celiac axis resection alone. This more extensive surgery is safe and feasible for selected patients with pancreatic cancer. PMID:24159408

  5. Computed tomography of adrenal Cushing's adenoma

    International Nuclear Information System (INIS)

    CT findings of 22 patients with surgically confirmed adrenal Cushing's adenomas were compared with pathologic findings. The cut surfaces of the adenomas showed mixture of yellow and brown areas in various proportions and were classified into three patterns; speckled brown areas in yellow background, geometrically brown areas in yellow background, totally brown or black surface. The maximum diameters of the cut surfaces were measured. The CT appearances of Cushing's adenomas after intravenous contrast administration have various patterns of enhancement and classified into three patterns; speckled, geometrical, and homoenous. The maximum diameters of the adenomas in CT images were also measured. Correlation between the CT and gross appearances of the specimens showed that while brown areas in adenomas were strongly enhanced, yellow areas were poorly enhanced. Histologically, brown areas in adenomas consist of compact-like cells with rich intercellular space and yellow areas consist of clear-like cells with poor intercellular space. The patterns of contrast enhancement some to depend on the cell types of adenomas. Difference in the intercellular space between compact and clear-like cells may have altered the patterns of contrast enhancement. The study also revealed that predominantly brownish adenomas were smaller in size than predominantly yellowish ones. As compact-like cells which make up the brown areas in Cushing's adenoma are thought to be more active in producing and secreting steroid hormones than clear-like cells, this result suggests that clinical symptoms may appear earlier in predominantly brownish adenomas than in predominantly yellowish ones.

  6. Vesicle Pools: Lessons from Adrenal Chromaffin Cells

    Full Text Available The adrenal chromaffin cell serves as a model system to study fast Ca2+-dependent exocytosis. Membrane capacitance measurements in combination with Ca2+ uncaging offers a temporal resolution in the millisecond range and reveals that catecholamine release occurs in three distinct phases. Release of a readily releasable (RRP and a slowly releasable (SRP pool are followed by sustained release, due to maturation and release of vesicles which were not release-ready at the start of the stimulus. Trains of depolarizations, a more physiological stimulus, induce release from a small immediately releasable pool of vesicles residing adjacent to calcium channels, as well as from the RRP. The SRP is poorly activated by depolarization. A sequential model, in which non-releasable docked vesicles are primed to a slowly releasable state, and then further mature to the readily releasable state, has been proposed. The docked state, dependent on membrane proximity, requires SNAP-25, synaptotagmin and syntaxin. The ablation or modification of SNAP-25 and syntaxin, components of the SNARE complex, as well as of synaptotagmin, the calcium sensor, and modulators such complexins and Snapin alter the properties and/or magnitudes of different phases of release, and in particular can ablate the RRP. These results indicate that the composition of the SNARE complex and its interaction with modulatory molecules drives priming and provides a molecular basis for different pools of releasable vesicles.

    Metastasis is a complex process that propagates cells from the primary or initial site of the cancer occurrence to distant parts of the body. Cancer cells break from the cancer site and circulate through the bloodstream or lymph vessels, allowing them to reach nearly all parts of the body. These circulating tumour cells (CTCs) contain specialized metastasis-initiating cells (MICs) that reside in the biological heterogeneous primary tumour. Researchers have hypothesized that metastasis of rena...

    In bilateral thumb amputations, the functional impairment is serious and every attempt should be made to reconstruct the thumb. We report a case of bilateral post traumatic thumb amputation, reconstructed with bilateral second toe transfer. Only two such cases have been reported in literature so far. Though there are various modalities for the reconstruction of thumb, microvascular toe transfer has its own merits. The convalescent period is minimal with excellent function. It is bilaterally s...

    Full Text Available Modern radiological technology has transformed the way that adrenal lesions are currently investigated. The contemporary radiologist has been catapulted to the forefront in the management of adrenal disease. With the increasing use of cross-sectional imaging, adrenal lesions are being serendipitously discovered in radiological studies undertaken for non-adrenal-related conditions – the so-called adrenal ‘incidentaloma’. This review discusses the imaging modalities available for characterising these lesions, highlighting current concepts and controversies in differentiating benign from malignant pathology. The article also provides a brief overview of the spectrum of adrenal pathology commonly encountered in the adult population.

    Little information is available on medical imaging of the adrenal glands in horses. We investigated the feasibility of transrectal ultrasonography to characterize the normal equine adrenal gland. Transrectal ultrasonography was performed in 25 healthy horses using a 7.5 MHz linear array probe at a displayed depth of 8 cm. Transrectal ultrasonography of the right adrenal gland was not feasible. For the left adrenal gland, the left kidney, the abdominal aorta, the left renal artery, the left renal vein, and the cranial mesenteric artery were used as landmarks. The size of the left adrenal gland was variable, but it generally appeared as a long, flat structure with a hyperechoic medulla surrounded by a hypoechoic cortex. The most cranial part of the gland could not be delineated appropriately in 11 horses (44%). The mean (+/-SD) thickness of the gland and medulla was 0.66 +/- 0.15cm (n = 25) and 0.28 +/- 0.09 cm (n = 25) near the caudal pole, 0.87 +/- 0.25 cm (n = 14) and 0.40 +/- 0.18 cm (n = 12) near the cranial pole, and 0.89 +/- 0.18 cm (n = 25) and 0.36 +/- 0.13 cm (n = 25) in the middle of the gland, respectively. The mean (+/-SD) length of the entire adrenal gland and of the medulla was 6.22 +/- 0.77 cm (n = 14) and 5.45 +/- 0.71 cm (n = 6), respectively. Transrectal ultrasonography allowed adequate visualization of the left adrenal gland in horses. PMID:20973389

    Androgen refractory prostate cancer metastasis is a major clinical challenge.Mechanism-based approaches to treating prostate cancer metastasis require an understanding of the developmental origin of the metastasis-initiating cell.Properties of prostate cancer metastases such as plasticity with respect to differentiated phenotype and androgen independence are consistent with the transformation of a prostate epithelial progenitor or stem cell leading to metastasis.This review focuses upon current evidence and concepts addressing the identification and properties of normal prostate stem or progenitor cells and their transformed counterparts.

    Full Text Available Milia en plaque (MEP is an extremely rare form of milia that is characterized by a number of milia-like cysts on an erythematous base and histologically exhibits features of keratin cysts. The etiology is not exactly known. MEP is generally seen among middle-aged women and especially on the head and neck region. Many of the diagnosed cases are localized in the retroauricular region, eyelids and the nose region. To date, no case of MEP in the auricula has been reported in the literature. In this article, we present the case of a 71-year-old female patient clinically and histologically diagnosed with bilateral auricular milia en plaque (in the external ear canal in the light of current literature.

    Unlike other non-gynecologic solid tumors, such as breast cancer, lung cancer, metastasis to bone from endometrial carcinoma is rare, metastasis to extremity is extremely rare. We report a 51-year-old multiparous woman with FIGO Stage IVb Grade 2 endometrial adenocarcinoma which metastasized to left lower extremity bone. She received an amputation of left lower extremity below the knees, and a total abdominal hysterectomy and bilateral salpingo-oophorectomy, and followed by systemic chemotherapy, radiation therapy to the pelvis and progestational agent. She had a complete response to above treatments, and disease-free survival for 10 months. After recurrence, she received chemotherapy, radiotherapy and progestational agent once again. She had lived 56 months and is still alive by the time of report. Metastasis of endometrial carcinoma to extremity bone can rarely occur and should be considered when the patient with endometrial carcinoma complained of unexplained pain and swelling associated with extremity bone.

Clinical findings and complementary studies suggested a bilateral atherogenic embolic event. Initially, she presented a superior branch retinal artery occlusion in her right eye followed by a central retinal artery occlusion with cilioretinal artery sparing in her left eye. Some conservative maneuvers performed did not improve visual acuity in the left eye. Supra-aortic Doppler ultrasonography revealed mild right internal carotid artery stenosis and moderate left internal carotid artery stenosis with a small, smooth, and homogeneous plaque. The transthoracic echocardiography showed a severe calcification of the mitral valve with a mild-moderate rim of stenosis. Central retinal artery occlusion and branch retinal artery occlusion are characterized by painless monocular loss of vision. Clinical approach and management attempt to treat the acute event, find the source of the vascular occlusion, and prevent further vascular events from occurring. Giant cell arteritis is a potentially treatable cause of central retinal artery occlusion and should be excluded in every single patient over 50 years old.Keywords: loss of vision, branch retinal artery occlusion, central retinal artery occlusion, Hollenhorst plaque

    Full Text Available Penile cancer as primary disease is relatively rare in developed countries. The penis is a rare site of metastases in spite of its rich vascularization. Approximately 500 cases have been reported in the literature; almost 70% of primary lesions are of pelvic origin (from genitourinary or recto-sigmoid primary tumors. We describe a case of penile metastasis from lung cancer. The rarity of the event prompted us to also explore related reviews and discuss the incidence, physiopathology, diagnosis and therapy of penile secondary cancer.

    Full Text Available Osteosarcoma is the most common primary malignant mesenchymal tumor, accounting for approximately 20% of sarcomas, with 5% incidence in the jaws. They present various clinical and histological aspects as well as variable disease prognosis and outcome. About 50% of all osteosarcomas are osteoblastic, 25% fibroblastic, 25% chondroblastic. Metastasis of osteosarcoma in the oral cavity is rare, and very few cases have been described so far in the literature. This article presents a metastatic case of chondroblastic osteosarcoma in the mandibular right-attached gingiva arising from 4 th rib. This case report further suggests that chondroblastic osteosarcoma has poor prognosis.
