| 摘 要：肾集合管癌（collecting duct carcinoma，CDC）又称Bellini导管癌，是一种极少见的肾脏恶性肿瘤。其影像学表现主要包括：肾髓质的定位；实性或囊实性肿块；侵袭性的生长方式；囊变常见；轻度、不均匀性强化；MRI T2WI上信号偏低；呈高18F-FDG摄取灶等。当出现上述影像特征时，CDC可作为重要的鉴别诊断加以分析。文章主要就其临床表现、病理及影像学诊断作一综述。 |

| Abstract: Collecting duct carcinoma(CDC) of the kidney，also known as Bellini duct carcinoma，is a very rare variant of renal cell carcinoma(RCC). The informative imaging findings of the CDC include medullary location，solid or complex solid and cystic mass，infiltrative growth，a cystic component，weak and heterogeneous enhancement，low-intense signal of T2WI on MR images and strong uptake of 18F-FDG,etc. When a renal tumor has these imaging findings，CDC might serve as a valuable differential diagnosis. The clinical manifestation，pathology and imaging diagnosis of CDC were reviewed. |
