pheochromocytoma is a catecholamine‑producing tumor. there are a very few reported cases of clinical pheochromocytoma. here, we report a 27‑year‑old woman para 1 live 1 with chief complaint of headache, confusion, nausea, and vomiting 2 days after cesarean section. she was anxious and had palpitation. on physical examination, fever, tachycardia, tachypnea, high blood pressure, and right thyroid...

Pheochromocytomas and paragangliomas are tumors of the autonomic nervous system; pheochromocytomas are tumors of the adrenal medulla, and paragangliomas are extraadrenal tumors arising from either the sympathetic nervous system or parasympathetic ganglia. It has previously been estimated that approximately 10%–15% of pheochromocytomas are due to hereditary causes. However, our increased underst...

Recent guidelines recommend consideration of genetic screening in all newly diagnosed patients with pheochromocytoma. Patients diagnosed with pheochromocytoma in the Region of Southern Denmark during 2006-2013 without previously recognized monogenetic etiology were offered genetic screening for mutations in the VHL, RET, SDHB, SDHC, and SDHD genes. A total of 41 patients were included, and gene...

Excess concentrations of catecholamines in pheochromocytoma can cause various clinical manifestations. There are few reports of pheochromocytoma presented with stress-induced cardiomyopathy (catecholamine-induced cardiomyopathy) after mild stress and the case of pheochromocytoma associated with nonocclusive stroke is more uncommon. We report a case of pheochromocytoma manifested repeated stress...

Introduction: The present study was aimed to assess the diagnostic performance of the two imaging methods of 131I-metaiodobenzylguanidine (131I-MIBG) and 99mTc-hydrazinonicotinyl-Tyr3-Octreotide (99mTc-HYNIC-TOC) in diagnosis and localization of pheochromocytoma and neuroblastoma. Methods: This study ...

Extra-adrenal pheochromocytoma is rare and presents variable symptoms. Its difficulty to diagnosis delays appropriate treatment. We would like to report an unusual case of extra-adrenal pheochromocytoma. The patient came to the emergency room with dyspnea, palpitation, and cyanosis. He had a history of hospitalization for Fontan operation due to congenital heart disease. Despite medication, his...

Pheochromocytoma is a rare cause of secondary hypertension. Presentation varies from asymptomatic to paroxysmal hypertension, palpitations, flushing, syncope, and even shock or death. Diagnosis is often delayed because pheochromocytoma is not considered a likely diagnosis. We present the case of a 47-year-old male that presented with hypertensive emergency. Several diagnostic tests were perform...

Neurofibromatosis type 1 is a complex, multi-system genetic disorder that is associated with an increased prevalence of pheochromocytoma and paraganglioma compared to the general population, 1.0%-5.7% versus 0.2%-0.6%, respectively. A delay in pheochromocytoma and paraganglioma diagnosis or undiagnosed pheochromocytoma and paraganglioma, as seen in normotensive and asymptomatic patients, may po...

OBJECTIVES Adrenal pheochromocytomas are rare neuroendocrine tumours, however their prevalence is probably underestimated - in some series 50% were diagnosed at autopsy. The clinical presentation varies among patients, that is why diagnosis might be difficult to establish. Pheochromocytoma may coexist with paraganglioma and when paraganglioma is diagnosed, the patient should be screened for phe...
