Approximately 15% of cases of renal cell carcinoma present cystic configuration on radiologic and pathologic examination. These lesions are often difficult to differentiate from the multiloculated renal cyst or other benign cystic lesions such as hemorrhagic cyst and so on. We report a case of multilocular cyst of the right kidney complicated with clear cell type renal cell carcinoma in which MRI suggested benign cyst. The diagnosis of complicated benign cyst must be proposed very cautiously and the persistence of doubtful images justifies surgical exploration.
约15%的肾细胞癌病例在影像学和病理学检查中呈现囊性结构。这些病变往往难以与多房性肾囊肿或其他良性囊性病变（如出血性囊肿等）相鉴别。我们报告一例右肾多房性囊肿合并透明细胞型肾细胞癌的病例，其中磁共振成像（MRI）提示为良性囊肿。对于复杂良性囊肿的诊断必须非常谨慎，而可疑图像的持续存在证明手术探查是合理的。
