| 目的 总结胆管错构瘤的超声图像特征，提高超声对其的诊断和鉴别诊断能力。方法 回顾性分析我院37例经MRI或病理检查证实为胆管错构瘤患者的超声影像资料，总结其特异性超声图像特征有：1.肝内弥漫分布的不规则囊性变；2.肝内多发的偏高回声结节；3.肝内弥漫分布的点状强回声伴彗尾征。（具体包括哪些？请列出）。结果 37例胆管错构瘤超声多表现为肝内弥漫分布不规则囊性病变，直径＜1.5 cm（97.3%）；肝脏弥漫性回声增粗（78.4%）；肝内多发偏高回声结节，直径＜1.0 cm（54.1%）；肝内弥漫分布的点状强回声伴彗尾征（56.8%）；肝包膜光整（94.6%）。平均LSM（7.16±1.99）kPa。结论 肝脏胆管错构瘤的超声表现具有特征性，对其典型超声表现的判读可提高对该病的超声诊断能力，减少误诊。 |

| ABSTRACT Objective To improve the ability of diagnosis and differential diagnosis of Bile Duct Hamartomas by exploring the characteristics of ultrasound.Methods From January 2015 to May 2020，37 patients with MRI confirmed BDH in our hospital （3 of whom were diagnosed by pathology） were retrospectively analyzed to summarize the sonographic characteristics. To summarize the ultrasonic image characteristics:1.Irregular cystic changes with the diffuse distribution in the liver; 2. Multiple hyperechoic nodules in the liver; 3. The diffuse punctate strong echo with comet tail features in the liver. Results In 37 cases of BDH ，Ultrasound diagnosis was found in 25 cases of BDH ，6 cases of diffuse liver lesions ，4 cases of hepatocirrhosis and 2 cases of hepatic multiple cysts.Characteristics of ultrasonic image：a .intrahepatic diffuse irregular cystic pathological changes （diameter less than 1.5 cm）（97.3%）；b.diffuse echo thickening in b liver （78.4%）; c.multiple hyperechoic nodules in c liver （diameter less than 10 cm）（54.1%）; d.high light spots diffusely distributed in the d liver with tail sign （56.8%）; e.liver capsule finishing （94.6%）; f.liver stiffness （LSM）LSM：7.16±1.99kpa。Conclusion The ultrasound findings of cholangihamartoma in the liver are characteristic, and the interpretation of the typical ultrasound findings can improve the ultrasound diagnostic ability of the disease and reduce misdiagnosis. |
