Extranodal lymphoma is not uncommon; however, lymphomatous involvement of the wall of the bile duct is rare, with only a few case reports available. Three cases were imaged with computed tomography (CT) and direct cholangiography at our institution. In one, Hodgkin disease recurred in the duct wall, producing a radiographic pattern indistinguishable from sclerosing cholangitis. In another, central sclerosis on cholangiography was associated with a separate liver mass identified by CT. This presentation of non-Hodgkin lymphoma mimicked cholangiocarcinoma. The third patient had multifocal, diffuse histiocytic lymphoma arising in the gallbladder and cystic duct, as well as in the kidneys and pancreas. Although the condition is unusual, the diagnosis of lymphoma in the bile duct wall should be considered, particularly when the cholangiographic picture of diffuse central sclerosis is associated with little or no observable mass on CT.
结外淋巴瘤并不罕见；然而，胆管壁的淋巴瘤累及却很罕见，仅有少数病例报告。我院有3例通过计算机断层扫描（CT）和直接胆管造影成像。其中1例，霍奇金病在胆管壁复发，产生了与硬化性胆管炎难以区分的放射学表现。另一例，胆管造影显示的中央硬化与CT发现的一个独立肝脏肿块有关。这种非霍奇金淋巴瘤的表现酷似胆管癌。第3例患者的多灶性、弥漫性组织细胞淋巴瘤发生于胆囊和胆囊管，以及肾脏和胰腺。尽管这种情况不常见，但胆管壁淋巴瘤的诊断应予以考虑，尤其是当弥漫性中央硬化的胆管造影表现与CT上几乎没有或没有可观察到的肿块相关时。
