Clinics in diagnostic imaging (109). Nocardial adrenal abscess.

A 34-year-old man presented with a two-month history of intermittent fever and left loin pain. A large left suprarenal mass was detected on computed tomography and magnetic resonance imaging. Blood pressure, serum electrolytes, serum cortisol and urinary catecholamines were normal. Laparoscopic adrenalectomy was planned but the mass was found to be an isolated adrenal abscess due to Nocardiosis. He was later found to have AIDS. The clinical utility of various imaging modalities and management of adrenal cysts are reviewed.
