Dilatation of the common bile duct is rarely caused by cystic formations. Though the pathogenesis is uncertain, congenital disorders have been suggested. Most cases are observed in small children (80% female predominance) with only 20% of the cases reported in adults. Clinical signs vary. Recurrent acute pancreatitis has been reported but is rare. New imaging techniques using CT-scan cholangiography and sometimes MR cholangiography have greatly improved the diagnostic approach. MR of the bile ducts is a recent noninvasive technique enabling an analysis of the biliopancreatic ducts without contrast injection into the bile. To our knowledge, cystic dilatation of the common bile duct has not been previously reported in the literature. We report an interesting case in a 25-year-old woman who developed an episode of acute pancreatitis during the post partum period. We describe the clinical aspects and the different imaging findings, including magnetic resonance cholangiography results.
胆总管扩张很少由囊性病变引起。尽管发病机制尚不清楚，但有人提出可能是先天性疾病。大多数病例见于小儿（女性占80%），仅20%的病例报道于成人。临床症状各异。曾有复发性急性胰腺炎的报道，但很罕见。使用CT扫描胆管造影术以及有时联合磁共振胆管造影术的新成像技术极大地改进了诊断方法。胆管磁共振成像术是一种最新的非侵入性技术，无需向胆管内注射造影剂就能分析胆胰管。据我们所知，此前文献中尚未报道过胆总管囊性扩张。我们报告一例有趣的病例，一名25岁女性在产后发生了一次急性胰腺炎发作。我们描述了临床情况以及不同的影像学表现，包括磁共振胆管造影结果。
