A giant common bile duct (CBD) calculus is a rare occurrence, and the presence of a giant calculus within a choledochal cyst (CDC) is even more unusual. In this case report, we detail an instance of a giant CBD calculus measuring 7 cm x 3 cm found within a CDC, accompanied by multiple tiny calculi. Magnetic resonance cholangiopancreatography (MRCP) revealed the dilation of the bi-lobar intrahepatic biliary radical (IHBR) and the CBD. A large T2 hypointense and T1 hyperintense calculus occupied the dilated CBD and common hepatic duct (CHD), extending into the left hepatic duct (LHD) and right hepatic duct (RHD). There was a possibility of type 1c CDC with cystolithiasis, hepatolithiasis, and cholelithiasis. The patient underwent open cholecystectomy with choledochotomy, stone retrieval, excision of the CDC, and Roux-en-Y hepaticojejunostomy.
巨大胆总管结石较为罕见,而胆总管囊肿(CDC)内出现巨大结石则更为少见。在本病例报告中,我们详细介绍了一例在CDC内发现的大小为7 cm×3 cm的巨大胆总管结石病例,同时伴有多个微小结石。磁共振胆胰管造影(MRCP)显示双侧肝内胆管分支(IHBR)和胆总管扩张。一个大的T2低信号和T1高信号结石占据了扩张的胆总管和肝总管(CHD),延伸至左肝管(LHD)和右肝管(RHD)。存在1c型CDC合并胆囊结石、肝内胆管结石和胆结石的可能性。患者接受了开腹胆囊切除术、胆总管切开取石术、CDC切除术和Roux-en-Y肝空肠吻合术。
