Which condition is included in the differential diagnosis of an adrenal incidentaloma?

• A. Pheochromocytoma
• B. Hepatic hemangioma
• C. Ovarian cyst
• D. Renal cell carcinoma

Answer: (A)

An adrenal incidentaloma is an unexpected mass found in the adrenal gland, and part of its evaluation is to consider tumors that could originate there and other conditions that might mimic an adrenal lesion. Pheochromocytoma is a tumor of the adrenal medulla that can present as an incidental adrenal mass and may secrete catecholamines. This makes it a key item in the differential because identifying or ruling it out before any intervention is crucial—catecholamine release during biopsy or surgery can cause severe hypertension or other dangerous events. The other choices lie outside the adrenal gland (liver, pelvis, kidney) and thus do not belong to the adrenal incidentaloma differential.
