超声造影诊断“团块型”肝内胆管局限性发育异常1例

Focal dysplasia of intrahepatic bile ducts diagnosed by contrast-enhanced ultrasound: A case report

局限于某一肝段、且表现为肝脏团块的肝内胆管的发育异常,临床少见,无特异性症状、体征及实验室检查结果,仅影像学检查能发现,超声检查尤其超声造影有一定的特征性表现,能很好地与肝脏其他占位性病变鉴别,但其诊断须更多地病例积累,其治疗和预后须更多病例的观察和总结.

Focal dysplasia, mimicking a mass, confined to intrahepatic bile ducts of a liver segment, is rare clinically. Since there are no specific symptoms, signs and laboratory findings, this disease is difficult to diagnose. It can be found only by imaging examinations. Especially, it shows some characteristics different from other liver space-occupying lesions on contrastenhanced ultrasound.
