A case of bilateral pheochromocytoma during pregnancy.

Pheochromocytoma is a disease where catecholamines are secreted. If pheochromocytoma occurs during pregnancy, it can be difficult to diagnose because it is similar to pregnancy-induced hypertension. F...

Epinephrine-secreting large incidental pheochromocytoma in a normotensive male with stormy intraoperative hemodynamics.

Pheochromocytoma is a rare tumour which is usually suggested by sustained or paroxysmal hypertension however the spectrum of the presentation of pheochromocytoma continues to expand and hypertension m...

Quantitative Versus Qualitative Methods in Evaluation of T2 Signal Intensity to Improve Accuracy in Diagnosis of Pheochromocytoma.

The purpose of this study was to assess T2 signal intensity (SI) of adrenal pheochromocytoma at 1.5 T using the rapid acquisitions with relaxation enhancement (RARE) sequence. We also sought to determ...

Pheochromocytoma - why is its early diagnosis so important for patient?

Pheochromocytoma may present with various clinical signs, symptoms due to continuous and/or paroxysmal release of catecholamines. Arterial hypertension may be sustained and/or paroxysmal and palpitati...

Coronary Bypass Surgery in the Presence of Metastatic Pheochromocytoma.

The hemodynamic management of a patient with a pheochromocytoma presents special challenges due to the episodic release of catecholamines from the tumor, which threatens to provoke a hypertensive cris...

Medical and Biotech [MESH] Definitions

A selective adrenergic alpha-1 antagonist used in the treatment of heart failure, hypertension, pheochromocytoma, Raynaud's syndrome, prostatic hypertrophy, and urinary retention.

A benzodioxane alpha-adrenergic blocking agent with considerable stimulatory action. It has been used to diagnose PHEOCHROMOCYTOMA and as an antihypertensive agent.

An inhibitor of the enzyme TYROSINE 3-MONOOXYGENASE, and consequently of the synthesis of catecholamines. It is used to control the symptoms of excessive sympathetic stimulation in patients with PHEOCHROMOCYTOMA. (Martindale, The Extra Pharmacopoeia, 30th ed)

A nonselective alpha-adrenergic antagonist. It is used in the treatment of hypertension and hypertensive emergencies, pheochromocytoma, vasospasm of RAYNAUD DISEASE and frostbite, clonidine withdrawal syndrome, impotence, and peripheral vascular disease.

A neural crest tumor usually derived from the chromoreceptor tissue of a paraganglion, such as the carotid body, or medulla of the adrenal gland (usually called a chromaffinoma or pheochromocytoma). It is more common in women than in men. (Stedman, 25th ed; from Segen, Dictionary of Modern Medicine, 1992)
