Preoperative chemical-shift magnetic resonance images in a 56-year-old man suggested the presence of microscopic fat in the tumor. The surgical specimen showed a granular-cell renal cell carcinoma with papillary architecture, associated with abundant fat-containing foamy histiocytes in the interstitium. The radiologist should include this entity in the differential diagnoses of renal tumors that contain microscopic fat.
一名56岁男性的术前化学位移磁共振成像显示肿瘤内存在微小脂肪。手术标本显示为具有乳头状结构的颗粒细胞肾细胞癌，间质中有大量含脂肪的泡沫状组织细胞。放射科医生应将该实体纳入含有微小脂肪的肾肿瘤的鉴别诊断中。
