| 摘 要： | 目的 分析囊肿型胆道闭锁（CBA）的MRI和MR胰胆管造影（MRCP）表现。方法 回顾性分析24例经手术病理证实的CBA患儿术前MRCP及MRI资料，结合术中造影及病理结果，分析CBA的影像学特点。结果 24例CBA，MRI均显示肝门区囊状结构，11例出现肝门区门静脉周围T2WI高信号，23例显示胆囊宽径明显小于长径，1例胆囊未显示；5例显示肝门区纤维斑块。24例CBA患儿MRCP均可见肝外胆总管区囊性结构，位于肝门区22例，位于左右肝管区2例；18例肝门区囊肿与胆囊管相通。结论 肝门区囊肿及纤维斑块、胆囊大小、形态及MRCP显示的肝外胆管情况是诊断CBA的重要征象。MRCP对于早期诊断CBA具有一定价值。

| Abstract: | Objective To analyze MRI and MR cholangiopancreatography (MRCP) manifestations of cystic biliary atresia (CBA). Methods MRI and MRCP data of 24 CBA infants confirmed with operation and pathology were retrospectively analyzed. MRCP and MRI findings were observed combining with intraoperative radiography and pathological features. Results Cystic structure in the hepatic hilum were found in all 24 infants. T2WI high signal in periportal area was showed in 11 infants. The width of the gallbladder was obviously shorter than the length in 23 infants, while gallbladder was absent in 1 infant. Fibrous plaque in the hepatic portal area was observed in 5 infants. Cystic structure located at hepatic hilum in 22 infants, at the left or right hepatic duct area in 2 infants. The cysts of the hepatic portals area were interlinked with the cystic duct in 18 infants. Conclusion Hepatic hilar cyst, hilar fiber block, morphology of gallbladder and common bile duct in MRCP are important signs for diagnosis of CBA. MRCP has a certain value in early diagnosis of CBA. |
