摘要 目的探讨肾集合管癌的CT表现以提高术前诊断准确性。方法回顾性分析5例经手术病理证实的肾集合管癌术前螺旋CT动态增强扫描表现。结果 5例中男性2例、女性3例,5例均为单侧发病,4例为肾皮质-髓质型、1例为肾皮质-髓质-肾盂型。5例肾脏体积均增大、局部轮廓突出;肿瘤形态不规则、与肾实质分界不清,3例肿瘤突破肾皮质侵犯包膜或腰大肌,1例累及肾窦,2例有腹膜后多发淋巴结转移。5例肿瘤大小自5cm×5.5cm至5.5cm×7cm不等,瘤内密度不均匀,1例瘤内有钙化,4例有囊样液性低密度区。增强CT三期扫描示肿瘤实体强化均呈轻-中等度强化,强化过程呈渐进性并延迟持续强化。结论肾集合管癌的CT表现有一定特征性,通过仔细观察影像学特征性表现及结合临床表现,对该病术前可作出提示性的诊断,确诊仍需依靠病理。
