We report on a 23-year-old woman with a right adrenal tumor 13 cm in diameter who was treated by laparoscopy. The patient was asymptomatic, and the tumor was incidentally diagnosed on abdominal ultrasonography. A subsequent computed tomography (CT) of the abdomen confirmed a 12 x 7 x 8-cm homogenous mass of the right adrenal. Magnetic resonance imaging (MRI) showed a solid mass measuring 13 x 7 x 7.5 cm arising from the right adrenal. Laparoscopic complete excision of the mass was accomplished through a transabdominal lateral approach. The postoperative period was uneventful, and the patient was discharged on the second postoperative day. Histology was consistent with an adrenal ganglioneuroma. Two years later, there is no evidence of recurrence on abdominal CT scan.
