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.
