Pheochromocytoma
Key Points
Hypertension may be constant or episodic. Diagnosis involves demonstrating high levels of catecholamine products (typically plasma free metanephrines in the serum or 24-hour metanephrines in the urine). Tumors should be localized with imaging tests, sometimes using radiolabeled compounds. A combination of alpha-blockers and beta-blockers are given pending tumor removal.
