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.
本文报告一例双侧肾上腺髓样脂肪瘤。患者为一名40岁男性，超声检查意外发现腹膜后肿瘤。计算机断层扫描显示双侧肾上腺肿块，右侧直径14.0 cm，左侧直径5.0 cm，伴有不均匀低密度成分。磁共振成像也显示出一个具有异质性的高强度肿块。肾上腺功能实验室检查结果正常。我们确诊为双侧肾上腺髓样脂肪瘤，并进行了右侧肾上腺切除术和左侧肿瘤剜除术。右侧肿瘤大小为14.0×12.5×10.0 cm，重量920 g，左侧肿瘤大小为5.0×4.5×4.0 cm，重量50 g。病理检查显示成熟脂肪组织和类似骨髓的造血成分混合存在。组织病理学诊断为肾上腺髓样脂肪瘤。该病例是日本文献中报道的第6例双侧肾上腺髓样脂肪瘤。
