目的:探讨儿童先天性胆管囊肿的 CT 诊断。材料与方法:40例儿童先天性胆管囊肿中,平扫40例,增强25例,胆系造影CT(CTC)10例。全部病例均作 B 超。40例中,男16例,女24例,年龄3天～11岁(平均3岁)。39例经手术和病理证实,1例经 B超、CT 和肝肾动脉造影确诊。结果:(1)肝外胆管囊肿35例,表现为肝门至胰头间圆形或椭圆形近水样低密度灶,增强无强化,CTC 示高密度造影剂进入囊腔内。邻近组织和器官不同程度受压;(2)肝内胆管囊肿(即 Caroli’s 病)1例,示肝内胆管呈“串珠状”、“分节状”低密度灶,增强无强化,有中心点征。合并双侧髓质海绵肾;(3)肝内、外胆管囊肿4倒,除上述征象外,肝内、外同时发病是其特点。结论:儿童先天性胆管囊肿的 CT 表现具有一定特征性,尤其是 CTC 具有十分可靠的定性诊断价值。
Objective: To investigate CT diagnosis of congenital cholangiocarcinoma in children. Materials and Methods: Forty children with congenital choledochal cyst were enrolled in this study. Forty cases were enrolled in this study, including 25 cases of enhancement and 10 cases of choledocholithiasis (CTC). All cases were made B-ultrasound. In 40 cases, 16 males and 24 females, aged 3 days to 11 years (mean 3 years). 39 cases were confirmed by surgery and pathology, 1 case was diagnosed by B ultrasound, CT and liver and renal artery angiography. Results: (1) 35 cases of extrahepatic bile duct cyst showed hepatic to pancreatic head round or oval near water-like low-density lesions, enhanced without enhancement, CTC showed high-density contrast agent into the cysts. Adjacent tissues and organs to varying degrees of compression; (2) intrahepatic bile duct cyst (Caroli’s disease) in 1 case, showed intrahepatic bile duct was “beaded”, “sub-node” low density lesions, enhanced without strengthening , There is a central point sign. Combined with bilateral medullary sponge kidney; (3) intrahepatic and extrahepatic biliary cyst 4 down, in addition to the above signs, intrahepatic and external disease is its characteristics. Conclusion: The CT manifestations of children with congenital cholangiocarcinoma have certain characteristics, especially CTC has a very reliable qualitative diagnostic value.
