Adrenal myelolipoma is a rare, benign tumour composed of adipose and haematopoietic cells. It is usually an incidental finding or may present in the form of a complication, the most severe being spontaneous retroperitoneal rupture. Computed tomography is the best examination, providing a preoperative diagnosis in 90% of cases. Adrenal aspiration cytology is useful in the case of a persistent doubt concerning the diagnosis. The principal differential diagnosis consists of an angiomyolipoma of the upper pole of the kidney. The indications for surgical resection are limited to symptomatic tumours, tumours larger than 5 cm in diameter and in the case of a doubtful diagnosis.
肾上腺髓质脂肪瘤是一种罕见的良性肿瘤，由脂肪和造血细胞组成。它通常是偶然发现的，或者可能以并发症的形式出现，最严重的是自发性腹膜后破裂。计算机断层扫描是最佳检查方法，90%的病例可在术前作出诊断。对于诊断仍有疑问的病例，肾上腺穿刺细胞学检查很有用。主要的鉴别诊断包括肾上极血管平滑肌脂肪瘤。手术切除的指征仅限于有症状的肿瘤、直径大于5厘米的肿瘤以及诊断存疑的情况。
