1、·200·影像诊断与介入放射学2014年第23卷第3期·腹部影像学·人体肝脏巨片形吸虫感染影像学表现李琴杜伟张靓顾伟潘云【摘要】目的探讨人体肝巨片形吸虫病的影像学表现特点及其诊断价值。方法回顾分析经临床确诊26例肝巨片形吸虫病患者的临床、病理及影像学表现。26例行CT平扫检查,其中24例行CT增强。9例行MRI平扫检查,其中7例行MRI增强。2例行肝穿刺病理学检查。结果26例CT平扫示肝肿大并实质内弥漫斑片状密度减低影,边界欠清,15例病灶相互融合呈簇状或隧道样病灶,以包膜下肝实质内为主,其中24例CT增强病灶不均匀轻度强化;
2、19例脾轻度增大。9例MRI平扫示为肝肿大并实质弥漫性病变,病变呈稍长T。、稍长T:,DWI上呈稍高或高信号改变;7例增强扫描呈蜂窝状稍强化;5例MRCP示肝内胆管及胆总管未见扩张或梗阻。2例穿刺病理活检表现为寄生虫性肉芽肿与坏死,周围大量单核细胞和嗜酸性粒细胞浸润。结论人体肝巨片形吸虫感染的CT、MRI表现为肝包膜下多发微小脓肿,部分呈簇状或隧道样特点,结合血清学检查,有助于早期诊断。【关键词l肝;巨片形吸虫;体层摄影术,x线计算机;磁共振成像;活检Imagingfindingsofhepaticfasciolagigant
