Adrenal schwannoma: An uncommon incidentaloma

Abstract

WHO classification of adrenal tumors. Only a handful of cases have been reported so far. A 30-year-old lady presented with cerebrovascular accident. CT scans of the abdomen and pelvis revealed a 3.5-cm well-defined, smooth margined, heterogeneously enhancing, mass lesion in the right adrenal gland. She had no endocrine symptoms and urinary metanephnines were normal. She underwent right adrenalectomy for incidentaloma. Histopathology of the excised mass showed features of an adrenal schwannoma. Diagnosis of adrenal schwannoma on imaging studies is difficult preoperatively and raises suspicion of other adrenal tumors. Surgical excision followed by histopathology confirms the diagnosis.
