Pheochromocytoma presenting with upper abdominal pain and hypertensive crisis: A case report

Abstract

Pheochromocytoma (PHEO) is a rare and complex molecularly driven endocrine disease that can present with a variety of clinical manifestations, including paroxysmal hypertension, episodic anxiety, tremors, devastating acute heart failure and acute pulmonary edema. The variety of PHEO-related symptoms increase the difficulty of identifying and diagnosing PHEO. We reported a case of a 27-year-old Chinese male was diagnosed PHEO by CT scan because of upper abdominal pain. The patient complicated with hypertensive crisis and headache following his admission, and he was underwent adrenal tumor surgical resection by carrying out appropriate clinical, laboratory and radiological imaging. Thus, the patient's PHEO-related symptoms were relieved and the blood pressure returned to normal, and discharged from the hospital with a follow-up plan. Although the PEHO-related symptoms are varied and difficult to diagnose, CT examination can be used for the preliminary detection and diagnosis. This case report emphasizes the importance of considering PHEO by CT scan and atypical symptoms, which help others better understand PHEO for early detection and timely surgical treatment to reduce catecholamine-related complications.
