A well-marginated fat-containing renal lesion gives strong suspicion of renal angiomyolipoma (RAML) that usually requires no surgical intervention. Radiologically, renal masses with a large amount of fat can rule out renal cell carcinoma (RCC). Calcifications are very infrequent in RAML. However, the presence of calcifications in a fat-containing renal lesion is highly suggestive of RCC. These lesions should undergo surgical resection and histopathological assessment to reach the right diagnosis and avoid poor outcomes if diagnosed late. We present a case of bilateral renal tumors, in which one of them radiologically contained abundant fat with calcifications on CT scan, which was confirmed to be an RCC on histopathological examination.
边界清晰的含脂肪肾病变高度怀疑为肾血管平滑肌脂肪瘤（RAML），通常无需手术干预。在放射学上，含有大量脂肪的肾肿块可排除肾细胞癌（RCC）。RAML中钙化非常罕见。然而，含脂肪的肾病变中出现钙化强烈提示为RCC。这些病变应进行手术切除和组织病理学评估，以做出正确诊断，避免延误诊断导致不良后果。我们报告一例双侧肾肿瘤病例，其中一个肿瘤在CT扫描上放射学表现为含有丰富脂肪并伴有钙化，经组织病理学检查证实为RCC。
