摘　　要：目的　探讨肝泡状棘球蚴病的CT表现特征。资料与方法　 50例经手术病理或穿刺活检证实的肝泡状棘球蚴病行常规CT或螺旋CT双期动态扫描 ,分析其CT表现。结果　 50例中单发病灶 38例 ,多发病灶 1 2例 ,钙化发生率为 93 %。根据CT表现可分巨块型 (包括实性肿块型 ,肿块液化型 ,钙化型 )、结节型和混合型。肿块和结节内出现直径 0 .2～ 0 .8cm小囊泡。病灶侵犯肝门 6例 ,4例出现肝外转移。结论　肝泡状棘球蚴病CT表现有一定特征性 ,结合临床 ,诊断不难。Objective To discuss CT features and classification of hepatic alveolar echinococcosis. Materials and Methods Conventional or Helical dual phase dynamic enhanced CT scanning was performed in 50 patients with surgically or pathologically proved hepatic alveolar echinococcosis. CT findings were analyzed.Results Of 50 cases, single lesion was seen in 38 and multiple in 12. Calcifications occurred in 93% of cases. Based on CT manifestations, the lesions were classified into three types. (1) Massive type, which could be subdivided into solid, liquefactive and calcified types. (2) Nodular type. (3) Mixed type. Small nodular calcification and vesicles (0.2～0.8 cm in diameter) were found in almost all lesions of nodular and mixed type. Involvement of porta hepatis and extrahepatic organs was seen in 6 and 4 cases, respectively.Conclusion Hepatic alveolar echinococcosis carries some certain CT features. Usually, it is not difficult to make a correct diagnosis when clinical information is taken into account. CT classification may be helpful for clinical management.
