We retrospectively reviewed abdominal computed tomographic (CT) studies from 20 patients with sclerosing cholangitis and found evidence of abdominal lymphadenopathy in 13 patients. Enlargement occurred primarily in areas draining the liver, such as the gastrohepatic ligament or celiac axis (N = 8), the porta hepatis (N = 7), and the pancreaticoduodenal region (N = 2). One patient had reactive adenopathy and retroperitoneal fibrosis. The presence of benign reactive lymphadenopathy in at least one intraabdominal location was confirmed by pathological examination of excised lymph nodes in seven patients. Malignancy was excluded by surgical exploration or clinical follow-up. We conclude that enlarged lymph nodes are a common finding by CT in patients with sclerosing cholangitis. Enlarged reactive lymph nodes in this condition should not be mistaken for evidence of periportal metastasis or cholangiocarcinoma.
我们回顾性分析了20例硬化性胆管炎患者的腹部计算机断层扫描（CT）研究，发现13例患者有腹部淋巴结肿大的证据。肿大主要发生在肝脏引流区域，如肝胃韧带或腹腔干（8例）、肝门（7例）和胰十二指肠区域（2例）。1例患者有反应性淋巴结病和腹膜后纤维化。7例患者经切除淋巴结的病理检查证实至少有一个腹腔内位置存在良性反应性淋巴结病。通过手术探查或临床随访排除了恶性肿瘤。我们得出结论，淋巴结肿大是硬化性胆管炎患者CT检查的常见表现。在这种情况下，肿大的反应性淋巴结不应被误认为是门静脉周围转移或胆管癌的证据。
