摘要
目的 探讨超声与CT对肝泡球蚴病的诊断价值。方法 对23例肝泡球蚴病进行B型超声检查和普通CT扫描,必要时增强扫描。结果 23例中巨块型10例,结节型2例,坏死、液化型6例,混合型5例。超声表现为肝脏局限性或弥漫性肿大,肿块与周围组织境界不清或外形不规整,凹凸不平呈“菜花”状,内部显示不均匀结节状、小囊状或点粒状、小片状钙化灶回声,病灶坏死区腔壁不规整,回声增强。CT的主要特征为病变部位组织密度严重不均匀,其内显示斑片状钙化灶,病变中心坏死腔液化呈水样密度,周边见“晕影征”。结论 CT增强扫描对泡球蚴病有肯定价值,超声检查操作方便,敏感性高,有一定特异性。
Objective To explore the ultrasound and CT diagnosing value for live alveolar hydatid diseas.Methods Twenty three cases of liver alveolar hydatid disease were examined by B ultrasound,routine CT scanning and necessary enhanced scanning.Results Of 23 cases,there were 10 massive shape,3 node shape,6 liquefied necrosis,5 mixed shape.Ultrasonographic findings showed localized of diffused liver tumfaction,the boundary between the tumor and surrounding tissure was not clear or the outer of the tumor was irregular and conveoconcave with cauliflower like shape,the inside of the tumor was of irregular node shape,small vesicular shape or spot and grain shape,small piece shape with calcific focal echo,focal necrosis region,and irregular parietal echo enhanced.CT findings showed that tissue density in pathological region was quite heterogeneous,the inside of which had psoriasis calcified foci,the center of which was necrotic and liquefied cavity with watery density,around which “dizzy shadowsign” was seen.Conclusions Examining by CT enhanced scanning has a positive value to alveolar hydatid disease,and examining by ultrasound is easy to operate,very sensitive and has a certain specificity,which is the first chosen examining method to liver alveolar hydatid disease.
