Adrenal myelolipomas are rare benign tumors consisting of mature fat and hematopoietic elements resembling bone marrow. Due to the frequent use of ultrasound and computerized tomography their presence is now more frequently discovered. Although these tumors are usually asymptomatic and only found incidentally at autopsy, they can cause local symptomes or hemorrhage requiring surgical excision. We present the case of a large surgically and histologically confirmed, adrenal myelolipoma with retroperitoneal hemorrhage due to spontaneous rupture in a 32-year old man.
