The bile duct of Luschka (BDL) is an anatomic anomaly that is an important cause of bile leakage after bile duct surgery. We report a case of bile duct carcinoma with dilated BDL that was diagnosed by ultrasonography (US). An 83-year-old man presented with an obstructive jaundice. US on admission revealed the presence of a solid hypoechoic mass in the bile duct at the hepatic duct confluence and a branch of the bile duct, about 2-4 mm in diameter, distinct from the dilated right anterior hepatic duct slightly upstream of the tumor. This branch had a spiral structure, extended along the gallbladder bed on the surface of segment 5 (S5) of the liver, and emanated small branches that entered the hepatic parenchyma. There has been no previous report of delineation of BDL by preoperative US.
卢施卡胆管（BDL）是一种解剖学异常，是胆管手术后胆汁漏的重要原因。我们报告一例经超声检查（US）诊断为BDL扩张的胆管癌病例。一名83岁男性出现梗阻性黄疸。入院时的超声检查显示在肝管汇合处的胆管及一条胆管分支内有一个实性低回声肿块，直径约2 - 4毫米，与肿瘤稍上游扩张的右肝前叶胆管不同。该分支具有螺旋结构，沿肝脏第5段（S5）表面的胆囊床延伸，并发出进入肝实质的小分支。此前尚无术前超声检查描绘BDL的报道。
