为了进一步研究ＣＴ对肾细胞癌的诊断价值，笔者分析了经手术切除病理证实的１１２例肾细胞癌的临床ＣＴ表现。结果ＣＴ特征表现为：（１）８４例肿块呈分叶状，边界不清，有短毛刺，并与肾周筋膜相连；（２）１７例肿块周边弧线状或中心斑点状钙化；（３）４６例肿块直径超过５ｃｍ者，密度不均，增强后坏死、囊变呈更低密度区；（４）８例直径≤３ｃｍ的小肾癌，长在肾实质内，边缘较清楚，密度不均。并就肿瘤分期及鉴别诊断进行了讨论。认为ＣＴ是诊断肾细胞癌最有价值的检查方法之一，ＣＴ表现可为术前定性诊断及术前分期，确定治疗方案及估计预后提供重要依据。分叶状肿块边缘有短毛刺并与肾周筋膜相连是肾细胞癌的特征性表现。
In order to further study the diagnostic value of CT on renal cell carcinoma, the author analyzed the clinical manifestations of 112 cases of renal cell carcinoma confirmed by surgical resection. Results The CT features were as follows: (1) 84 cases were lobulated with unclear border, short burr and connected with perirenal fascia; (2) 3) 46 cases of tumors with a diameter of more than 5 cm had uneven density and increased necrosis with cystic degeneration in a lower density area. (4) 8 cases of small renal cell carcinoma with a diameter of ≤3 cm grew within the renal parenchyma with a clear edge, Uneven. Tumor staging and differential diagnosis were discussed. That CT is one of the most valuable diagnostic methods for the diagnosis of renal cell carcinoma, CT performance for preoperative qualitative diagnosis and preoperative staging to determine the treatment options and provide an important basis for the estimation of prognosis. Lobulated tumor edge with a short burr and perineal fascia connected with renal cell carcinoma is a characteristic manifestation.
