摘　　要：目的：探讨多房囊性肾细胞癌（MCRCC）的影像学及病理学特点，提高术前诊断水平。方法回顾性分析20例MCRCC的临床资料，分析影像学、病理学、手术方式及预后特点。结果术前诊断肾癌16例，肾癌坏死2例，肾复杂囊肿2例；行肾部分切除术16例，肾根治性切除术4例；术后病理18例提示MCRCC ，2例提示肾透明细胞癌合并MCRCC。术后随访14～120个月，平均36个月，均未见明确的肿瘤复发和转移。结论 MCRCC病因不明、恶性程度低、预后良好，提高影像学检查技术可在术前提示诊断MCRCC ，治疗以保留肾单位的手术方式为佳。ABSTRACT：Objective To investigate the imaging and pathological features of multilocular cystic renal cell carcinoma （MCRCC） .Methods Clinical data of 20 cases of MCRCC were retrospectively analyzed .The imaging and pathological fea‐tures ,surgical procedures ,and follow‐up outcomes were studied .Results Before operation ,16 cases were diagnosed as renal cell carcinoma ,2 as necrosis caused by renal cell carcinoma and 2 as complex renal cyst .Four cases underwent radical nephrec‐tomy while the other 16 partial nephrectomy . Histological examination showed that 18 cases were MCRCC , and 2 were MCRCC complicated with clear cell carcinoma .During the follow‐up of 14‐120 months （mean 36 months） ,all patients sur‐vived ,with no evidence of metastasis or recurrence .Conclusions MCRCC is characteristic of unknown etiology ,low malig‐nancy ,low pathological grade and favorable prognosis .Preoperative imaging is helpful in the diagnosis .Kidney‐sparing surgery is preferred in the treatment .
