Abstract
Ninety patients, found to have lymph nodes in the hepato-duodenal ligament (HDL) on ultrasound examination were reviewed over a one-year period in order to define the diseases in which such nodes can be found. The patients were divided into four main groups: benign liver disease (n = 31), malignant disease (n = 26), disease of the gallbladder or the biliary tree (n = 14) and a group with various benign, most inflammatory diseases (n = 19). In 40% of the patients (36/90), the lymph nodes in the HDL were the only sign of disease on ultrasound examination, and the majority of those were in the benign group.
