摘要
We present a case of a 72-year-old man with a common bile duct cancer, who was initially believed to have multiple liver metastases based on computed tomography findings, and in whom magnetic resonance cholangiography （MRC） revealed a diagnosis of bile duct hamartomas. At exploration for pancreaticoduodenectomy, liver palpation revealed disseminated nodules at the surface of the liver. These nodules showed gray-white nodular lesions of about 0.5 cm in diameter scattered on the surface of both liver lobes, which were looked like multiple liver metastases from bile duct cancer. Frozen section of the liver biopsy disclosed multiple bile ducts with slightly dilated lumens embedded in the collagenous stroma characteristics of multiple bile duct hamartomas （BDHs）. Only two reports have described the MRC features of bile duct hamartomas. Of all imaging procedures, MRC provides the most relevant features for the imaging diagnosis of bile duct hamartomas.
我们在场是的有胆总管癌症的一个 72 岁的人的一个盒子开始相信了吃多重肝转移基于计算断层摄影术调查结果，并且在磁性的回声胆管造影术(MRC ) 在谁揭示胆汁管 hamartomas 的诊断。在为 pancreaticoduodenectomy 的探索，肝触诊在肝的表面揭示了传播小瘤。这些小瘤在在两片肝脑叶的表面上散布的直径显示出大约 0.5 厘米的灰色白人的榴状的损害，它被看起来像从胆汁管癌的多重肝转移。肝活体检视的冰冻切片揭示了多重胆汁管，稍微扩大的腔在多重胆汁管 hamartomas (BDH ) 的成胶的基质特征嵌入。仅仅二份报告描述了胆汁管 hamartomas 的 MRC 特征。所有成像过程， MRC 为胆汁管 hamartomas 的成像诊断提供最相关的特征。
