Myelolipomas are relatively rare benign tumors, frequently associated with the adrenal glands. Usually, they are non-functioning, asymptomatic and measure less than 5 cm. Bilateral giant adrenal myelolipomas are rare. We report the first case of bilateral giant adrenal myelolipomas of the Latin American literature: a 57-year old woman who presented with left abdominal pain. The computed tomography scanning revealed bilateral suprarenal masses measuring 9 x 7 x 6.5 cm on the right and 23 x 19 x 8 cm on the left. The masses were radiographically consistent with fatty tissue. The preoperative diagnosis was liposarcoma. Surgery was performed with excision of the masses. The histologic analysis identified bilateral adrenal myelolipomas. Although they are benign tumors, surgery must be performed because only the histologic analysis can exclude malignancy.
