摘　　要：目的探讨低度恶性潜能多房囊性肾瘤(multilocular cystic renal cell neoplasm of low malignant potential,MCRCNLMP)的超声造影表现。方法收集术前常规超声及超声造影检查并经手术病理证实的21例MCRCNLMP病灶,对比常规超声及彩色多普勒超声,观察其超声造影表现,根据Bosniak标准分级,分析总结其超声造影特点。结果 21例MCRCNLMP病灶内常规超声仅有1例未见囊内分隔,余20例均可见数条分隔,平均厚度为(2.15±0.90)mm,囊内分隔的厚度与分隔血流相关(P=0.020)。21例病灶超声造影均可见明显增强分隔,平均厚度为(2.54±0.66)mm,在超声造影与常规超声上病灶内分隔厚度的差异有统计学意义(P=0.023),而在超声造影与常规超声上病灶内分隔条数的差异无统计学意义(P=0.305)。MCRCNLMP病灶按Bosniak标准分级分为ⅡF级～Ⅳ级,其中大部分病灶为Bosniak Ⅲ级。结论超声造影诊断MCRCNLMP较常规超声能准确鉴别分隔上有无血供,临床上筛查时若测及囊性团块内较多分隔的病灶建议行超声造影检查。Objective To retrospectively investigate the contrast enhanced ultrasound （CEUS） characteristics of muhilocular cystic renal cell neoplasm of low malignant potential （MCRCNLMP）. Methods Twenty one lesions pathologically approved as MCRCNLMP, which underwent both preoperative conventional ultrasound and CEUS in our hospital, were enrolled in this retrospective study. The CEUS images were compared with those of conventional and color Doppler ultrasound. Meanwhile, all the 21 lesions were analyzed and categorized based on the Bosniak classification. Results On conventional uhrasound,1 case showed no septa inside the lesion and the other 20 lesions demonstrated few to many septa inside. The mean thickness of MCRCNLMP lesions was （2.15 ± 0.90） ram. There was correlation between the thickness of the septa and the existence of blood flow wihtin the septa on conventional ultrasound （P=0. 020）. The mean thickness of the enhanced septa was （2.54 ± 0.66） mm, which was significantly higher than that on conventional ultrasound （P=0. 023）.According to Bosniak classification, MCRCNLMPs were classified as category Ⅱ F Ⅳ, and the majority of them were category Ⅲ. Conclusions The presence of blood on the separation of MCRCNLMP can be identified accurately by CEUS than conventional ultrasound. The patient with cystic lesion should be suggested to undergo CEUS when there is few to many septa within the lesion on conventional ultrasound.
