Objective To investigate the CT features of liver abscess of different etiology. Methods The CT findings and clinical data of 54 liver abscess cases were retrospectively analyzed. Results The CT findings of liver abscess were lower density lesions than those of normal liver tissue. The target signs of liver abscess, cluster sign and gas inside abscess were the characteristic signs of CT diagnosis. The etiological diagnosis of liver abscess include pyogenic liver abscess, gallbladder liver abscess, amebic liver abscess and hepatic artery transcatheter arterial chemoembolization (TAE) postoperative abscess and other CT signs have certain characteristics. Conclusions CT features not only confirm the location of the liver abscess, but also diagnose the nature and etiology of the liver abscess
