A 51-year old obese man had been followed up for diabetes mellitus and hypertension. Hepatomegaly was noted on routine examination without any complaints in 1981. Through further investigation of the liver, a large hyperechoic mass lesion was shown between right kidney and the liver on ultrasonogram. On admission, diabetes was controlled by diet alone and blood pressure was 160/90 mmHg. without medication. There were no abnormal findings in laboratory data including hormone assays. The mass showed fat density on CT scan and hypovascularity on angiogram. The mass was diagnosed as benign non-functioning right adrenal tumor, most likely myelolipoma. By operation, the tumor was removed through long subcostal incision. The tumor was well defined and encapsulated, 14 X 8 X 8cm. in size and 480g. in weight. Microscopically the tumor was typical myelolipoma with a mixture of hematopoietic and adipose tissue. Postoperative course was uneventful and the patient discharged on 17-th postoperative day. Myelolipoma of the adrenal gland is a rare non-functioning benign tumor consisting of fat cell and bone marrow element. Only 30 resected cases of adrenal myelolipoma have been reported in the world including 7 cases in our country.
一名51岁的肥胖男子因糖尿病和高血压接受随访。1981年常规检查时发现肝脏肿大，但无任何不适主诉。通过对肝脏的进一步检查，超声检查显示右肾和肝脏之间有一个大的高回声肿块病变。入院时，糖尿病仅通过饮食控制，血压为160/90 mmHg，未用药。实验室检查数据包括激素检测均无异常发现。CT扫描显示肿块为脂肪密度，血管造影显示血供不足。该肿块被诊断为良性无功能右肾上腺肿瘤，很可能是髓脂肪瘤。通过手术，经长肋下切口切除肿瘤。肿瘤边界清晰，有包膜，大小为14×8×8cm，重量为480g。显微镜下，肿瘤为典型的髓脂肪瘤，由造血组织和脂肪组织混合而成。术后病程平稳，患者于术后第17天出院。肾上腺髓脂肪瘤是一种罕见的无功能良性肿瘤，由脂肪细胞和骨髓成分组成。世界上仅报道了30例肾上腺髓脂肪瘤切除病例，其中我国有7例。
