Diagnostic Considerations
Differentials to consider in the diagnosis of pheochromocytoma include the following:
- Alcohol withdrawal
- Labile essential hypertension
- Hyperventilation
- Orthostatic hypotension
- Multiple pharmacologic agents (monoamine oxidase inhibitors [MAOIs], decongestants, sympathomimetics)
- Illegal drug use (phencyclidine [PCP], lysergic acid diethylamide [LSD], cocaine)
- Migraine headache
- Autonomic neuropathy
- Stroke
- Toxemia of pregnancy
- Polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome
- Acute intermittent porphyria
- Cardiogenic pulmonary edema
- Renovascular hypertension
- Subarachnoid hemorrhage
- Lead toxicity
