Medical Definition of Pheochromocytoma
1.
A tumour of the adrenal gland which produces catecholamines (noradrenaline and adrenaline). Although the tumour is usually benign it produces hypertension, pounding headaches, tachycardia, palpitations, apprehension, facial flushing, nausea and vomiting.
A diagnosis can be made using a urine test which measures the quantity of adrenaline byproducts. Adrenal tumours may be detected by CT, MRI or a nuclear scan of the adrenal glands.
