肾上腺髓性脂肪瘤是一种少见的、无功能的良性肿瘤。只有当肿瘤体积明显增大或内部有出血及坏死时可产生临床症状，常见症状为腰酸或腰痛。我院超声科自１９８９年至１９９４年共查出６例，所有病例均手术证实，并将每例超声图像与病理切片图像进行比较，超声图像是以密集增强光团为特征，边界清晰，个别病例肿瘤内部合并出血时，可见不规则液性暗区；病理切片图像可见大量脂肪细胞和部分骨髓造血细胞，对于出血病例可在脂肪细胞周围见到成堆红细胞。超声和ＣＴ检查对本病的诊断有很大的价值
Adrenal myelolipoma is a rare, non-functioning benign tumor. Only when the tumor volume increases significantly or there is bleeding and necrosis inside can produce clinical symptoms, common symptoms are backache or low back pain. The Department of Ultrasound in our hospital had detected 6 cases from 1989 to 1994. All cases were confirmed by surgery. The ultrasound images were compared with the images of pathological sections. Ultrasound images were characterized by intense light-enhanced masses with clear boundaries. In case of intratumoral hemorrhage in the tumor, irregular fluid dark areas can be seen; in the pathological section, a large number of adipocytes and some bone marrow hematopoietic cells can be seen. For the hemorrhage cases, piles of red blood cells can be seen around adipocytes. Ultrasound and CT examination have great value in the diagnosis of this disease
