本文分析了经病理证实的15例肝泡状棘球蚴病的声像图表现,其中巨块型8例,占53.3%,结节型1例,占6.7%,坏死液化型3例,占20%,混合型3例,占20%.其声像图特征为:肝脏肿大,肿块与周围组织分界不清或外形不规整,凹凸不平呈"花菜"状,内部显示为不均匀结节状,小囊状高回声,有时见较小的钙化灶回声;病灶坏死腔可呈"溶洞"样透声区,腔壁回声增强.在进行诊断时应同肝囊型包虫病钙化、实性变、肝血管瘤、肝癌仔细鉴别.%The ultrasonographic characteristics of 15 cases of hydatidosis which were proved by pathology were analyzed.Among the 15 cases,8(53.3%)belonged to massive,1(6.7%) modular,3(20%)necrotic and liquified and 3(20%) mixed type.The ultrasonographic characteristics were:liver enlargement;the boundary betweem the tumor and the surrounding tissure was not clear;the outer shape of the tumor was irregular,undulant and cauliflower-like;inside the tumor,there was nonhomogeneous nodular and small cystic dense echo sometimes with echo of few calcified foci;the foci of the necrotic cavity showed cave-like echo free area with enhanced reflection of the wall.Differential diagnosies should be made among the consolidation and calification of the hepatic bydatid cyst,hepatic angioma and carcinoma.
