Pheochromocytoma Presenting as the Alternation of Hypertension and Hypotension

Abstract

We reported a rare case of pheochromocytoma presenting as the alternation of hypertension and hypotension, which highlighted the rare event of an extreme and cyclical blood pressure pattern in a pheochromocytoma hypertensive crisis. Early recognition is critical for selection of the appropriate treatment to terminate the effects of catecholamine storm, which prepares for surgical resection of the tumor.
