摘要
目的探讨胆囊脏面穿孔CT与MRI表现特征。资料与方法回顾性分析16例经手术病理证实或经多种影像检查确诊的胆囊脏面穿孔患者的多层螺旋CT(MDCT)与MRI表现,并结合临床情况进行综合分析。结果胆囊脏面穿孔的CT与MRI表现包括胆囊壁异常、胆囊脏面穿孔所致肝脏异常和胆囊周围及右上腹腔异常。胆囊壁异常包括胆囊壁局部缺损或突出正常轮廓外,壁呈分层状。肝脏异常表现为肝脓肿或胆汁瘤形成,胆囊床周围肝实质动脉期异常强化。胆囊周围及上腹腔异常包括胆囊窝及右上腹腔包裹性积液,胃窦、十二指肠、结肠肝曲、右半横结肠壁及邻近肠系膜肿胀。结论MDCT和MRI能够准确、全面地反映胆囊脏面穿孔的大体病理特征、累及范围和程度,为准确诊断和选择合理的治疗方案提供可靠的影像学信息。
Objective To investigate the CT and MRI features of gallbladder perforation in the visceral wall.Materials and Methods The MDCT and MRI features and clinic data of 16 cases with gallbladder perforation in the visceral wall confirmed by surgery or multiple imaging modalities were analyzed retrospectively.Results The CT and MRI findings were divided into primary changes of the gallbladder wall,liver changes,pericholecystic changes and findings of the right upper abdominal cavity. Primary changes of the gallbladder wall associated with gallbladder perforation included wall defect or focal bulging and stratification of the gallbladder wall. Liver changes included liver abscess or biloma formation and liver enhancement surrounding the gallbladder bed on the hepatic artery phase. The findings of extra-gallbladder organs included pericholecystic fluid collection,encapsulated fluid collection of the right upper abdominal cavity,wall swelling of the pyloric antrum and duodenum,right colic flexure and right transverse colon,and thickened mesentery.Conclusion Imaging features,invasion range and extent of gallbladder perforation in the visceral wall could be evaluated more accurately and comprehensively on MDCT and MRI,which would offer reliable image information to make correct diagnosis and rational choice for treatment.
