The CT, sonographic, and pathologic appearances of 13 surgically confirmed cases of papillary renal cell carcinoma were reviewed. CT-pathologic correlation was available in all 13 cases. Sonography was performed in eight patients (10 distinct renal masses). CT features closely correlated with the previously established clinicopathologic and angiographic appearances. Papillary renal cell carcinoma demonstrated low stage at presentation in most cases (10 of 13 had stage I or II), had a high frequency of calcification (seven), and had less enhancement (diminished vascularity) than typical hypernephroma on CT scans. No consistent sonographic pattern existed; one of 10 masses was hyperechoic, five were hypoechoic, and four were isoechoic compared with normal kidney cortex. On the basis of these observations, a prospective CT diagnosis of papillary renal cell carcinoma can be confidently made in many circumstances. This is particularly important when renal-sparing surgery is a clinical consideration.
回顾了13例经手术证实的乳头状肾细胞癌的CT、超声及病理表现。13例均有CT与病理的对照资料。8例患者（10个不同的肾肿块）接受了超声检查。CT表现与先前确立的临床病理及血管造影表现密切相关。乳头状肾细胞癌多数病例在就诊时处于低分期（13例中有10例为I期或II期），钙化发生率高（7例），在CT扫描上强化程度低于典型的肾细胞癌（血管减少）。超声表现无一致模式；与正常肾皮质相比，10个肿块中有1个为高回声，5个为低回声，4个为等回声。基于这些观察结果，在许多情况下可以可靠地做出乳头状肾细胞癌的CT前瞻性诊断。当保留肾手术成为临床考虑因素时，这一点尤为重要。
