目的：分析囊性肾癌的 CT 表现，探讨多层螺旋 CT 的诊断价值。方法：回顾性分析11例囊性肾癌的临床表现、CT 及病理资料。CT 成像技术为采用64排螺旋 CT 平扫及三期增强扫描，并行冠状位、矢状位的多平面重建。结果：11例囊性肾癌均显示为囊性或囊实性肿块，规则或不规则，大小不一，均有囊壁增厚。其中壁结节占9例，瘤内分隔占4例，囊壁钙化占4例。囊壁及分隔厚薄不均，增强后可见囊壁、囊内分隔及壁结节的强化，主要呈“快进快出”的特征。多平面重建图像显示肿瘤细节及其与周围结构关系更加清晰。结论：囊性肾癌具有一些特征性的 CT 征象，多层螺旋 CT 多期增强扫描及多平面重建有助于明确诊断，但需与肾脏其他囊性病变相鉴别。

Objective: To improve the diagnostic accuracy by analysis CT features of cystic renal cell carcinoma (CRCC). Methods: Retrospective analysis of 11 cases with complete clinical manifestations, CT examination and pathology of cystic renal carcinoma (CRCC) patients’ data were performed. All cases underwent 64-detector row spiral CT scans and three phase enhancement including cortex, medulla, and renal pelvis phase. Multiplanar reconstruction (MPR) includes coronal and sagittal reconstruction was subsequently obtained. Results: All cases were cystic or cystic-solid tumors with regular or irregular shape and with varied size. Of 11 cases with CRCC, 9 cases had mural nodular, 7 cases had intratumoral septum, and tumor cyst wall calcification was found in 4 cases. Uneven thickness of the cystic wall, septa of the cysts and mural nodular were enhanced, and the pattern of the enhancement in most of the cases was the same as in carcinoma. MPR images were helpful in illustrating the detail of the tumors and the relationship with adjacent structures. Conclusion: CRCC have typical features on CT. multi-phase enhanced scanning with multi-detector row spiral CT and MPR images is helpful for making a definite diagnosis, but differential diagnosis with other cystic renal lesions must be given.
