Multiple large lymph nodes in the hilar and peritoneal areas appear, and the possible diseases include hepatitis, gastric cancer metastasis, lymphoma, cirrhosis and so on. 1. Hepatitis: Inflammation of liver due to year-round drinking, viral infection, parasites, etc. Due to inflammation stimulation, local lymph nodes will be enlarged, such as in hepatoportal and/or peritoneal area. 2. Liver metastasis of gastric cancer: in the middle and late stages of gastric cancer, the cancer cells metastasize to the liver, causing enlarged lymph nodes in hepatoportal and peritoneal area, accompanied by epigastric pain, anemia, anorexia and other symptoms. 3. Lymphoma: originated from lymph nodes and lymphatic tissues, patients mainly manifest painless lymph node enlargement. When lymphoma occurs in the hilar and/or retroperitoneum, multiple enlarged lymph nodes will be found in that area. 4. In addition to the above diseases, cirrhosis of the liver and primary liver cancer may also cause the above situation. The above test results alone cannot accurately determine the cause, but need to be combined with the characteristics of the medical history and other test results to make an accurate judgment, and it is recommended to clarify the cause of the disease under the guidance of a doctor.
