我们回顾了33例患者的50次CT扫描，共37次肝脓肿。除1例(97%)外，其余均检出异常。然而，肝脓肿的特征性CT表现不明显。肝内病灶多为单发，但34%可见多发脓肿。病变的CT表现各不相同，从边界清晰的圆形空洞，内容物接近水密度，类似于边界不清的肝囊肿，到难以与肝肿瘤区分的高密度病灶。仅有19%的患者脓肿内有气体。边缘强化仅占6%。CT可能是发现肝脓肿的一种敏感检查，但通常不具特异性。
Fifty computed tomographic (CT) scans in 33 patients with 37 separate episodes of hepatic abscess were reviewed retrospectively. Abnormalities were detected in all but 1 case (97% sensitivity). However, a characteristic CT appearance of hepatic abscess was not evident. Most intrahepatic foci were solitary, but multiple abscesses were present in 34% of cases. The CT appearance of the lesions varied from well defined, rounded cavities with contents near water density, resembling poorly defined hepatic cysts, to higher-density foci indistinguishable from hepatic neoplasms. In only 19% was gas present within the abscess. Rim enhancement was seen in only 6%. CT is probably a sensitive test for detecting hepatic abscess, but is often nonspecific.
