摘要
目的探讨起源于肾髓质常见肾癌(嫌色细胞癌和集合管癌)的MSCT诊断及鉴别诊断价值。方法对已经手术病理证实的9例嫌色细胞癌和2例集合管癌术前的MSCT动态增强影像学特征进行回顾性分析及跟踪随访。结果根据TNM分期,9例肾嫌色细胞癌中,T1aN0M0期2例,T1bN0M0期3例,T2aN0M0期2例,T2bN0M0期2例;2例集合管癌均为T4N2M0期。结论 MSCT三期增强扫描后影像学特征对起源于肾髓质肾癌与肾皮质来源肾癌的鉴别诊断具有一定意义,有助于对肾癌病理亚型作出进一步诊断和判断预后及决定治疗方法和范围。
Objective To discuss multi-slice CT （MSCT） diagnosis and differential diagnosis of common renal cancers that are originated from renal medulla, including chromophobe cell carcinoma and collecting duct carcinoma. Methods A total of 9 patients with chromophobe cell carcinoma and 2 patients with collecting duct carcinoma encountered at author＇ s hospital were enrolled in this study. The diagnosis was surgically and pathologically proved in all patients. The preoperative dynamic enhanced MSCT imaging features were retrospectively analyzed. All the patients were followed up to check the re- suits. Results According to TNM staging, among 9 cases of chromophobe renal cell carcinoma, 2 belonged to TlaNOM0 stage, 3 belonged to T1 bNOM0 stage, 2 belonged to T2aNOM0 stage and 2 belonged to T2bNOM0 stage. Both two patients with collecting duct carcinoma belonged to T4N2M0 stage. Conclusion Imaging findings on MSCT three phase enhanced scanning are definitely helpful in diagnosing the common renal cancers that are originated from renal medulla as well as in differentiating it from the renal cancers that are originated from renal cortex. Besides, it helps to make a further diagnosis of the histological subtype, to evaluate the prognosis and to determine the therapeutic method.
