Abstract: Objective To investigate the clinical and CT manifestations of iatrogenic hepatic subcapsular biloma (HSB).Methods Seven cases with iatrogenic HSB confirmed by paracentesis in our hospital,and 18 reported in literatures were enrolled into this study.Their clinical and CT manifestations were retrospectively analyzed.Results Of the 25 cases,9 were secondary to laparoscopic cholecystectomy (LC),5 were secondary to percutaneous transhepatic choleductus drainage (PTCD),4 were secondary to percutaneous transhe-patic removal of bile duct stones,2 were secondary to open cholecystectomy,and 5 were secondary to other surgeries.CT showed localized or diffused hepatic subcapsular fluid collection with crescent-shaped or sac-shaped.The hepatic volume decreased and the surface was compressed in some of the cases with diffused fluid collection.Conclusion When localized or diffused hepatic subcapsular fluid collection was detected in CT imaging after liver or gallbladder surgeries (especially LC and PTCD),HSB should be considered.Paracentesis should be performed as soon as possible.
