Abstract
A 23-year-old man was incidentally diagnosed on CT scan with a 6.4 cm right adrenal mass during workup for acute abdominal pain, with interval growth to 9.4 cm over 3 months. Given the mass size and concern for potential malignancy, a right open adrenalectomy was performed. Pathologic evaluation confirmed a diagnosis of adrenal ganglioneuroma (AG) and the patient exhibited an unremarkable postoperative course. AGs are rare, benign tumors of the adrenal gland. Diagnosis is made by histopathologic assessment, and management of larger AGs is nearly always surgical given radiographic similarities between AG and malignancy. Adrenalectomy is generally curative for AG.
