Renal Lesions with Fat

Almost all fat-containing renal masses are angiomyolipomas. Fat density has been reported in renal cell carcinomas, but this is extremely rare. However, a mass that contains both fat and calcification is suspicious for renal cell carcinoma as angiomyolipomas rarely contain calcification.¹ Fat density without calcification has been reported in papillary renal cell carcinoma, secondary to adipose tissue¹ and cholesterol necrosis.² Papillary renal cell carcinomas tend to be more homogeneous and enhance less than clear cell carcinomas.³ Clear cell renal carcinomas often have intracytoplasmic fat, which can be detected by chemical shift magnetic resonance imaging (MRI),⁴ but do not have macroscopic fat detectable by computed tomography (CT).
