Cholelithiasis and/or obstructive biliary tract disease was diagnosed ultrasonographically in 8 horses, 5 to 15 years old. Ultrasonographic findings revealed greater than normal amount of hepatic parenchyma in the right side of the abdomen in 8 horses and in the left side in 3 horses. The echogenicity of the liver was greater than normal, and thick distended bile ducts were seen in all horses. Choleliths were imaged ultrasonographically in 6 horses. Subsequently, postmortem findings in 6 horses revealed periportal and intralobular fibrosis, moderate bile duct dilatation, proliferation, and cholestasis. One or more choleliths were found in all horses. Ultrasonographic findings accurately depicted the histologic changes in the hepatic parenchyma in horses with cholelithiasis.
超声检查诊断出8匹5至15岁的马患有胆结石和/或阻塞性胆道疾病。超声检查结果显示，8匹马的腹部右侧肝实质量多于正常，3匹马的腹部左侧肝实质量多于正常。肝脏的回声性高于正常，且所有马匹均可见胆管增厚扩张。6匹马的超声图像显示有胆结石。随后，6匹马的尸检结果显示门静脉周围和小叶内纤维化、中等程度的胆管扩张、增生和胆汁淤积。所有马匹均发现有一个或多个胆结石。超声检查结果准确地描绘了患有胆结石的马肝脏实质的组织学变化。
