Schwannoma of the adrenal gland is very rare, comprising 0.2% of adrenal tumors, presenting usually as non-specific abdominal pain. We report such a rare case in a 50-year-old female. Her only complaint was right lumbar pain. Ultrasonography (USG) and computed tomography (CT) both showed a supra renal cystic mass most likely of adrenal origin. Excision of mass was performed. Post-operative course was uneventful. Histopathology showed a benign tumor of Schwann cell origin. Usually, pre-operative imaging including CT and magnetic resonance imaging (MRI) are inconclusive and diagnosis has to be confirmed on histopathology.
