[Bilateral adrenal myelolipoma: a case report].
A case of bilateral adrenal myelolipoma is presented. The patient was a 40-year-old man in whom a retroperitoneal tumor was unexpectedly found by ultrasonography. Computed tomography revealed bilateral adrenal masses, 14.0 cm in diameter on the right side, and 5.0 cm on the left side, with heterogeneous low density components. Magnetic resonance imaging also revealed a high intensity mass with heterogeneity. Laboratory examination of adrenal function revealed normal results. We confirmed myelolipoma of bilateral adrenal gland, and performed right adrenalectomy, and left tumor enucleation. The right tumor was 14.0 x 12.5 x 10.0 cm in size and 920 g in weight, and the left tumor 5.0 x 4.5 x 4.0 cm in size and 50 g in weight. Pathology disclosed an admixture of mature adipose tissue and hematopoietic elements resembling bone marrow. Histopathological diagnosis was adrenal myelolipoma. This case was the 6th to be reported in the Japanese literature as bilateral adrenal myelolipoma.
