目的：探讨囊性肾癌的CT表现，以提高对囊性肾癌的认识和诊断符合率。方法回顾性分析16例经手术病理证实为囊性肾癌患者的CT影像学表现特点，16例均行CT平扫和增强扫描，6例同时行多平面重建。结果16例囊性肾癌均单发，位于左肾13例，右肾3例；多囊者11例，其内可见粗细不均分隔，单囊者5例；囊液密度不均匀15例；10例囊壁不均伴有壁结节；增强后囊壁和（或）分隔及结节呈不同程度的强化；2例病灶伴有钙化。结论囊性肾癌的CT主要表现为具有厚薄不均的囊壁和（或）粗细不均分隔、伴有囊壁结节及钙化的囊性病变，有一定特征性，具有重要的诊断价值。

Objective To discuss the features of cystic renal cellcarcinoma(CRCC),and to evaluate its clinical value. Methods This study included sixteen patients’s CT imaging features,who were proved pathological y to be CRCC after nephrectomy. Results Al cases were single,The tumor was located in left kidney in 13cases and right kidney in 3 cases;The cystic carcinoma showed multiple cystic cavities in 11 cases with irregular thickening septum,and single cystic cavity in 5 cases;Uneven density in the cavity in 15cases;unevencysticwal and mural nodule were found in10 cases;The solid part of the tumor in al the 10 cases was enhanced mode rately or strongly . Various degrees of cystic wal and/or septum and mural nodule enhanement were detected after intravenous administration 0f contrast material. Calcification were found in 2 cases. Conclusion Cystic renal carcinoma has certainCT characteristics,performance for the cystic lesion with unevencysticwal and /or irregular thickening septum、mural nodule and Calcification.CT can play an important role in diagnosis.
