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;MRIT2WI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。
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 18 F-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.
