We present a case in which the medial sectional bile duct (B4) drained the right hepatic duct. A 42-year-old man was referred to our hospital after an abdominal ultrasound during a medical check-up revealed a gallbladder polyp. Magnetic resonance cholangiopancreatography did not adequately depict the hepatic hilum bile ducts; therefore, drip infusion cholangiography with computed tomography was performed, which revealed that B4 drained the right hepatic duct. The patient subsequently underwent laparoscopic cholecystectomy. His post-operative course was uneventful, and he was discharged on post-operative Day 3. The confluence of B4 into the right hepatic duct is extremely rare. We report this case along with a brief review of the literature.
我们报告一例肝内段胆管（B4）引流右肝管的病例。一名42岁男性在体检时腹部超声发现胆囊息肉后转诊至我院。磁共振胰胆管造影未能充分显示肝门部胆管；因此，进行了CT滴注胆管造影，结果显示B4引流右肝管。该患者随后接受了腹腔镜胆囊切除术。术后恢复顺利，术后第3天出院。B4汇入右肝管的情况极为罕见。我们报告此病例并对相关文献作简要回顾。
