7109 "My Stomach hurts": A Rare Case of Adrenal Cortical Carcinoma

Abstract Disclosure: R.C. Attah: None. I. Sirisena: None. Pheochromocytoma/Paragangliomas are rare neurogenic tumors that arise from chromaffin cells present in the adrenal medulla or extra-adrenal paraganglia, these cells produce catecholamines. Typically, these tumors are discovered as incidentalomas. They can be hereditary as seen in genetic syndromes like multiple endocrine neoplasia type 2A or 2B, neurofibromatosis type 1 or Von Hippel Lindau syndrome but can occur sporadically. Patients typically present with hormonal hypersecretion signs or symptoms like abdominal pain, episodic headaches, sweating, hypertension and tachycardia, but some patients are asymptomatic. Patient is a 37-year-old female with past medical history of hypertension, type 2 diabetes mellitus and fatty liver who presented to the ED with abdominal pain for a few weeks. On arrival, her vitals were BP 205/124, HR 102, RR 14 and SpO2 100% on room air. CT abdomen was obtained which showed a 7.6 x 4.7 x 5.7 cm mass replacing left adrenal gland with small left retroperitoneal hemorrhage worrisome for adrenal cortical carcinoma, metastatic disease or pheochromocytoma. Hormonal workup revealed elevated 24-hr urine cortisol 124.2mcg (ref 4.0-50.0mcg/24h), normal aldosterone/renin ratio 10.63ng/dL (ref
