Abstract Disclosure: K. Chanturishvili: None. Q. Gvazava: None. N. Zavrashvili: None. An adrenal incidentaloma is a mass lesion greater than 1 cm in diameter, discovered by radiologic examination, performed for another reason. Widespread use of imaging studies in everyday clinical practice has led to the increased rates of adrenal incidentalomas. Two main questions arise after discovering adrenal mass: is it malignant or benign, and is the mass hormonally active?We present a case of a 55 years old male, with a history of obesity (BMI 35).He had no significant past medical history and was not taking any medications.He presented to our clinic with an upper respiratory tract infection and shortness of breath. Chest CT was done to evaluate for possible pneumonia, where 46 x 30 cm adrenal incidentaloma with -5 HU was discovered.He was referred to our department for endocrine evaluation.Initial assessment revealed previously unknown hypertension with left ventricular hypertrophy. Laboratory workup revealed high aldosterone, suppressed renin, low normal ACTH and DHEA-S, positive 1-mg overnight dexamethasone suppression test (DST- 2.66 ug/dL) and 8-mg DST (2.26 ug/dL).Additionally, the metabolic panel showed prediabetes and hyperlipidemia.Diagnosis of adrenal macroadenoma with cortisol and aldosterone co-secretion was made.Unilateral adrenalectomy was planned. Possible postoperative adrenal insufficiency has been established. Recommendation for proper glucocorticoid coverage was given.In conclusion, evaluation of the functional status of adrenal tumors is essential to uncover hidden medical issues, as s well as to properly guide the patient for intra and postoperative management, avoiding the risks of adrenal insufficiency with proper glucocorticoid coverage. Surgical management of hormonally active adrenal incidentalomas, especially larger 2.4 cm, has potential benefit of improving and preventing metabolic abnormalities: hyperglycemia, dyslipidemia as well as comorbidities such as obesity, hypertension and osteoporosis.
