What are mildly enlarged periportal and gastrohepatic ligament lymph nodes?

Mildly enlarged periportal and gastrohepatic ligament lymph nodes are usually seen in malignancies of the liver, gallbladder, pancreas, and lymphoma. For those with enlarged periportal and gastrohepatic ligament lymph nodes without evidence of the above malignancies, biopsies are recommended to ascertain where the malignant cells are coming from.
