Question:
A 32-year-old man presents to the emergency room with headache, palpitations, sweating, and anxiety for the past 30 minutes. His blood pressure is 220/110 mm Hg. Upon questioning the patient reports that he has experienced similar episodes intermittently over the last year, with complete resolution of symptoms between episodes. Further testing in this patient will most likely show which of the following?
Correct Answer: D. Elevated plasma free metanephrine
This patient likely has a pheochromocytoma. The classical presentation is paroxysmal hypertension associated with the triad of headaches, sweating, and palpitation. The best test for confirming pheochromocytoma is a finding of elevated plasma free metanephrine. The most practical and best confirmatory test for pheochromocytoma is urine VMA assessment.
