囊性肾细胞癌的CT影像诊断和病理表现

目的：分析囊性肾细胞癌的CT特征及病理表现。方法：回顾分析9例经手术病理证实且临床和影像资料完整的囊性肾细胞癌。结果：9例患者中，女性2例，男性7例，病灶均为单发，多为外生性生长。CT平扫囊性2例，囊实性7例，5例囊内容物内见碎屑或絮状物，2例囊壁见小结节状钙化。增强后囊壁、分隔及附壁结节呈不同程度强化，囊内容物未见明确强化。9例病变大体病理显示肿瘤均有厚薄不等的假纤维包膜围绕，切面见单一或大小不等的囊腔，内含浆液性或血性液体。镜下见囊腔上皮被覆肿瘤细胞。结论：囊性肾细胞癌CT表现为单发，囊壁、分隔及附壁结节呈不同程度强化，具有一定的特征性。

Imaging features and pathological findings of cystic renal cell carcinoma

Objective：To analyze CT features and pathologic findings of cystic renal cell carcinoma（ CRCC ）. Methods：Nine cases were confirmed by operation and pathology and the clinical and imaging data of cystic renal cell carcinoma were retrospectively analyzed. Results：Of the 9 patients,2 cases of female,7 cases of male,lesions were solitary,mostly exophytic growth. CT plain scan in 2 cases,cystic solid in 7 cases,debris or floc in 5 cases of cystic contents in 2 cases,cystic wall nodular calcification. After enhancement,cystic wall separating and mural nodule showed thickness ranging from false tumors all around,see section cavitysingle or with different sizes,including serous or bloody fluid. Cystic epithelial tumor cells coated with transparent microscopically. Conclusion：Cystic renal cell car-cinoma CT showed solitary,cystic wall,partition and mural nodule showed varying degrees of enhancement,has certain characteristics.
