Angiomyolipoma is a benign mesenchymal tumour of kidney that consists of adipose tissue, muscle cells and blood vessels. Renal angiomyolipomas represent almost one percent of all renal tumours. We reported a case of a 50-year-old woman complaining of mild abdominal discomfort with no other symptoms and no remarkable medical history. Clinical examination was inconclusive and no lump was palpable in abdomen. Ultrasonography raised the suspicion of existence of a large, homogeneous, hyperechoic tissue mass arising from right kidney. Abdominal computed tomography scan suggested the presence of giant angiomyolipoma of right kidney. The histopathological examination confirmed the diagnosis of renal angiomyolipoma. The patient underwent open simple nephrectomy to remove the tumour without any complications. We documented a rare case of retroperitoneal angiomyolipoma with extrusion of fat content from the renal hilum breaching the cortex as peculiarity which presented just as mild abdominal discomfort.
血管平滑肌脂肪瘤是一种肾脏的良性间叶性肿瘤，由脂肪组织、肌肉细胞和血管组成。肾血管平滑肌脂肪瘤几乎占所有肾肿瘤的1%。我们报告了一例50岁女性病例，该患者主诉轻度腹部不适，无其他症状，既往病史无特殊。临床检查无明确结果，腹部未触及肿块。超声检查怀疑右肾存在一个大的、均匀的、高回声组织团块。腹部计算机断层扫描提示右肾巨大血管平滑肌脂肪瘤。组织病理学检查确诊为肾血管平滑肌脂肪瘤。患者接受了开放性单纯肾切除术以切除肿瘤，无任何并发症。我们记录了一例罕见的腹膜后血管平滑肌脂肪瘤病例，其特点是脂肪成分从肾门挤出并突破皮质，最初仅表现为轻度腹部不适。
