肝内胆管错构瘤的超声诊断、误诊分析及相关探讨

Analysis on ultrasonic diagnosis and misdiagnostic causes of bile duct hamartoma in liver

目的探讨肝内胆管错构瘤的超声声像图特征,并对误诊原因进行分析。方法总结我院经MR诊断的11例肝内胆管错构瘤的超声特点,分析其声像图特征,查找误诊原因。结果 11例超声首诊仅2例正确,其余9例超声首诊误诊为慢性肝病、肝硬化7例,弥漫性肝癌2例;首诊的诊断符合率仅18.2%。4例超声复诊中确诊并与MR诊断符合。结论肝内胆管错构瘤声像图具有特征性,了解其典型超声表现,对提高本病的诊断及鉴别诊断具有重要价值。

Objective To investigate the nltrasonographic characters of bile duct hamartomas and to analyze the possible causes of misdiagnosis. Methods This retrospective study was on 11 cases of BDH which were diagnosed by MRI and the ultrasonic images were analyzed. Results Misdiagnosis as cirrhosis of liver was made in 7 cases, diffuse liver cancer in 2 cases of all 11 cases. The first diagnostic accordance rate was only 18.2% （2/11 ）. The 4 cases were diagnosed in the second ultrasonic examination and corresponds to MR. Conclusion The recognition of BDH ＇ s ultrasonic characteristics will improve the diagnostic value and the differential diagnostic value.
