Cystic Pheochromocytoma with Hypertensive Crisis and Classic Triad Diagnosed Using Point-of-care Ultrasound in the Emergency Department.

Pheochromocytoma is a rare catecholamine-secreting neuroendocrine tumor that commonly presents as hypertensive crisis with the classic triad of headache, sweating, and palpitations. However, it is challenging for emergency physicians to diagnose patients who initially present to the emergency department without a medical history. Here, we present the case of a patient diagnosed with cystic pheochromocytoma using point-of-care ultrasound in the emergency department.
