A 63-year-old man, who was diagnosed with sudden sensorineural hearing loss (SSHL), showed severe hypertension 10 hours after prednisolone administration. Subsequently, the patient suddenly died due to pulmonary edema. The autopsy indicated a pheochromocytoma in the right adrenal gland, and the cause of death was determined to be a pheochromocytoma crisis induced by systemic administration of p...

To investigate the release of neuropeptide Y (NPY) from the pheochromocytomas, we studied the relationship between the plasma and tumor tissue immunoreactive (IR) NPY concentrations in 13 patients with pheochromocytoma and measured the IR-NPY concentration in plasma samples obtained by catheter from several veins (jugular veins, superior vena cava, renal veins, adrenal veins and inferior vena c...

BACKGROUND Excessive catecholamine release in pheochromocytoma is known to cause transient reversible left ventricular (LV) dysfunction, such as in the case of pheochromocytoma-associated catecholamine cardiomyopathy. We investigated patterns of clinical presentation and incidence of LV dysfunction in patients with pheochromocytoma. METHODS From January 2004 to April 2011, consecutive patient...

Composite adrenal medullary tumors, composed of both pheochromocytoma and ganglioneuroma, are extremely rare, as are pheochromocytomas masquerading as acute relapsing pancreatitis. We recently experienced a case of a 48-year-old male with both these phenomena. The patient complained of an acute onset of intense abdominal discomfort. At the same time, pancreatic enzymes were increased in concent...

This case report describes a rare cause of refractory ventricular fibrillation which was identified as a clinical manifestation of pheochromocytoma. It illustrates the pitfalls of diagnostics and surgical treatment of pheochromocytoma and the dilemma whether to implant in such patient an implantable cardioverter-defibrillator (ICD). Although the cause of cardiac arrest accompanying pheochromocy...

INTRODUCTION Pheochromocytoma is a chromaffin cell catecholamine-secreting tumour originating from the adrenal medulla. CASE PRESENTATION We report here an unusual presentation of pheochromocytoma with secondary amenorrhoea and its resolution after medical treatment with the alpha adrenergic blocker, Phenoxybenzamine. CONCLUSION Pheochromocytoma is a rare cause of secondary amenorrhoea.

Pheochromocytoma is an uncommon tumor of the adrenal glands that can present with headaches, sweating, palpitations, and paroxysmal hypertension. Pheochromocytoma crisis can lead to cardiomyopathy, pulmonary edema, and even total circulatory collapse. We describe a patient with hypoxic respiratory failure requiring extracorporeal membrane oxygenation to stabilize until the pheochromocytoma was ...

We present a rare case of intra-abdominal hemorrhage due to a ruptured pheochromocytoma. Our patient presented with signs of shock. By emergency surgery, an hemorrhagic pheochromocytoma of the left adrenal gland was removed. Recovery was uneventful. In cases of suspected hemorrhagic pheochromocytoma with severe shock, prompt surgery is mandatory and catecholamines administration may be crucial ...

Since the hypotensive and natrluretic role recently attributed to dopamine (DA) is difficult to test (free DA is usually undetectable in plasma) we measured free and conjugated DA by a newly developed method of hydrolysis of conjugated catecholamlnes in four pheochromocytoma, four primary aldosteronism and 34 essential hypertensive patients subjected to selective venous catheterization or perip...
