不典型肝脓肿的动态增强CT表现与病理基础

Dynamic Enhanced CT Manifestations and Pathologic Basis in Atypical Liver Abscess

目的分析不典型肝脓肿的动态增强CT表现及病理基础。方法 24例经手术或临床证实的不典型肝脓肿患者纳入研究,回顾性分析其动态增强CT表现及相关病理学基础。结果不典型肝脓肿主要表现为增强动脉期病灶周围一过性肝段性强化,病灶分隔轻度强化;门脉期持续性强化,病灶范围缩小或不变。结论动态增强CT检查有助于不典型肝脓肿的诊断,熟悉CT征象及病理基础有利于提高疾病的诊断和鉴别诊断。

Objective To analyze the dynamic enhanced CT manifestations and pathologic basis in atypical hepatic abscess. Methods Dynamic enhanced CT findings and correlated pathologic basis in 24 cases of atypical hepatic abscess which were proven by operation or clinical data were retrospectively analyzed. Results In the arterial phase of enhanced CT, the slightly separating enhancement of the focus and temporal hepatic segments enhancement around the focus were found. In the portal vein phase, the persistent enhancement was found and the focus diminished or unchanged. Conclusion Dynamic enhanced CT examination is helpful in the diagnosis of atypical hepatic abscess. To be familiar with CT manifestations and pathologic basis is favorable to imnrove the diagnosis and differential diagnosis of the diseases.
