囊性肾细胞癌的CT诊断(附11例报道)

CT diagnosis of cystic renal cell carcinoma:Report of 11 cases

目的:探讨囊性肾癌的CT影像学表现及鉴别诊断,旨在提高术前诊断率。方法:回顾性分析11例囊性肾癌的CT影像学表现。结果:7例表现为多房样改变,囊内壁不光整,分隔厚薄不一,增强后呈中重度强化;4例表现为单房样改变,囊内见不均匀絮状影,增强后囊壁呈结节样异常强化,絮状物强化不明显。结论:囊性肾癌的CT影像学表现有一定的特征性,了解其特点有助于给临床术前提供一些重要信息。

Objective：To study the CT features of cystic renal cell carcinoma in order to improve accuracy of the preoperatiue diagnosis.Methods：The CT imaging data of 11 cases of cystic renal cell carcinoma confirmed by pathology were retrospectively analyzed.Results：Seven cases demonstrated multilocular cystic mass with irregular inner wall and septas,and the inner wall and septa were obviously enhanced.Four cases revealed unilocular cystic renal cell carcinoma with enhanced mural nodules and non-enhanced muddy cystic content.Conclusions：The cystic renal cell carcinoma has certain CT characteristics,which is of value for surgical operation.
