Adrenal Incidentaloma With the Diagnosis of Normotensive Pheochromocytoma: A Case Report

Background: Pheochromocytomas (PCCs) are catecholamine-producing neuroendocrine tumors that originate from the adrenal medulla. Their clinical presentations most commonly include hypertension, headache, palpitations, and sweating; however, PCCs sometimes normotensive clinically silent. Case Presentation: A female patient with abdominal pain as well persistent crushing left flank for past six months was examined. The imaging studies revealed a mass in upper pole of kidney indicative potential gland tumor; she had normal blood pressure (BP). Histopathologic examination exploratory laparotomy showed it PCC. Findings sonography computed tomography (CT) scan tumor, along elevated urinary normetanephrine level positive iodine-123 metaiodobenzylguanidine (MIBG) led to preoperative diagnosis PCC our case. Conclusion: This study highlighted importance biochemical testing diagnosing patients incidentalomas (AIs), even though they were entirely asymptomatic.
