Weight-loss with activation of brown fat: Suspect pheochromocytoma.
CONCLUSION: Brown fat activation may mislead diagnosis of pheochromocytoma, suggesting multi-metastatic extra-adrenal tumor, if clinicians are not aware of it. PMID: 31606198 [PubMed - as supplied by publisher]
Conclusion: Congenital polycythemia was clinically diagnosed, mimicking Chuvash polycythemia. Chuvash polycythemia is an autosomal recessive disorder that usually harbors a homozygous mutation of VHL598C>T but not predispose to pheochromocytoma development; in contrast our patient showed for the first time that the concurrent heterozygous VHL and TMEM mutations, resulted in a clinical phenotype of a normotensive patient with polycythemia due to erythropoietin-secreting pheochromocytoma that improved after adrenalectomy.
A 52-year-old male who had chronic hypertension for several years presented with abrupt epistaxis. The CT scan revealed a 40 mm × 40 mm mass in the nasal cavity intended to the maxillary sinus and the base of skull. Nasal endoscope biopsy and serum/urinary catecholamine detection conformed an ectopic noradrenaline-secreting pheochromocytoma. The present research was to discuss the clinical characteristics of the rare pheochromocytoma and the palliative interventional embolization for it.
ConclusionPheochromocytomas is a rare disease which may lead to a life-threathening hypertension as a result of elevated cathecolamine production. Initial recognition and appropriate management of pheochromocytomas are important. Preoperative management to normalize blood pressure followed by tumor removal has proved to be the ideal choice for good prognosis. Multidisciplinary team during preoperative, intraoperative and postoperative are required for successful outcome.
ConclusionEndocrine HT has many etiologies possibly responsible for high morbidity and mortality, especially when not properly diagnosed or treated. The potentially curable nature of endocrine HT in more than two thirds of cases, demonstrates the importance of early diagnosis of every severe HT resistant to treatment or in the presence of suggestive clinical, biological or radiological signs.
Conclusion: Most AIs are hormonally inactive adenomas. The most frequent hormonal manifestation of AI is subclinical hypercortisolemia. Presence of AI is often accompanied by features of metabolic syndrome. The tumor density on CT scan picture may be predictive of both hormonal activity and the risk of malignancy. Tumors of all sizes may exhibit hormonal activity, while the risk of malignancy significantly increases with the size above 6 cm.
Abstract This paper presents a case study of a patient that underwent surgery for a ruptured abdominal aneurysm. The postoperative course was complicated by resistant hypertension and tachycardia. A suprarenal mass was detected in the computed tomography scan with radiological suspicion of pheochromocytoma. Few cases of pheochromocytoma coexisting with aneurysms have been reported. Management of cardiovascular stability is crucial in such cases. Despite the lack of evidence, pheochromocytomas might have a role in the etiology of aortic aneurysms.

Abstract Pheochromocytomas and sympathetic paragangliomas are rare catecholamine-secreting tumors and represent very rare causes of intracerebral hemorrhage in young, with only few cases reported. A 32-year-old man presented to our emergency department because of sudden onset of severe headache. He had a six months history of paroxysmal headache, palpitations and sweating. During examination he became somnolent and developed left-sided hemiplegia. A computed tomographic (CT) scan of the brain showed a right temporoparietal hematoma. He was admitted to the Clinic for Neurosurgery and hematoma was evacuated. The pat...
We report herein three cases of major hepatectomy with IVC invasion and discuss several surgical tips.Patients and MethodsFrom March 2011 to February 2014, we retrospectively reviewed three cases of adrenal malignancy with liver and IVC invasion. Based on the severity of the malignant tumor, each case illustrates a different method to address surgical complications and maintain oncologic safety. Case 1: A 34-year-old woman was diagnosed with adrenocortical tumor during medical examination. Tumor invaded the right lobe of the liver and very close to the IVC. Fortunately, there was little thrombosis inside the IVC; we perfor...
ConclusionThis case brings to the attention of clinicians the need to have a high index of suspicion of a giant phaeochromocytoma in a patient presenting with vague abdominal symptoms whose CT scan shows a large retroperitoneal tumour, even in the absence of clinical symptoms and negative or absent biochemical workup.
