Giant adrenal myelolipoma treated by laparoscopic excision: A case report and review of literature

Abstract

Adrenal myelolipoma is inevitably a benign neoplasm of the adrenal gland. It is the second most common primary adrenal incidentaloma after adrenocortical adenomas. Adrenal myelolipoma is a rare, benign and non-functional neoplasm, composed of mature adipose and hematopoietic tissue which closely resembles bone marrow. Most of these lesions are small, unilateral and asymptomatic, discovered incidentally at autopsy or on imaging studies performed for other reasons. We report a case of this rare tumour in a 46-year-old obese male who had presented with vague abdominal pain on the right side past 6 months without any other significant history. Ultrasound and subsequently CECT scan abdomen showed a large well-circumscribed mass arising from the right adrenal gland, measuring 11×10cm. Laparoscopic right adrenalectomy was performed.
