肝脓肿的CT分析(附78例报告)

目的探讨肝脓肿的CT表现特征,着重讨论其与肝癌(HCC)的鉴别诊断.方法将78例已证实的肝脓肿CT图像与手术病理所见及同期证实的一组肝癌CT图像对照分析.结果25例无病灶周边"双靶征”或"牛眼征”及病灶内均匀液化坏死和积气等典型肝脓肿CT表现.53例有中央均匀液化坏死、病灶周边"双靶征”及病灶内积气等特征性CT表现.不典型肝脓肿多为早期肝脓肿,CT平扫表现无特征性,增强扫描可见周边多囊征,边缘锐利征,蜘蛛征,持续强化征.结论肝脓肿特征性和非特征性CT表现,有助于肝脓肿的诊断和鉴别诊断.

CT Diagnosis of Hepatic Abscess:An Analysis 78 Cases

Objective The CT features of hepatic abscess (HA) were studied to differentiate form hepatocellular carcinoma(HCC).Methods The CT and operative-pathological findings of 78 cases with HA were analyied and compared with the CT appearances of a series proven cases of HCC.Results None of 25 cases had the so-called typical findings such as the marginal"double-target sign"and the even liquidizing necrotic area and containing gas zone within the lesion,53 cases had the central even liquidizing necrotic area,the marginal "Double-target sign",and containing gas zone within the lesion.Most of a typical hepatic abscess were early HA,and the precontrast CT showed nonspecific features.There were characteristic features on contrast CT.They were peripheral multicyst sign,sharp-edged sign spider-like sign,continued enhancement sign.Conclusion The CT features of HA are very valuable for the diagnosis of HA and the differential diagnosis from HCC.
