Description
Abdominal lymph nodes are generally organized along the blood vessels within the abdominal cavity. These can be categorized into parietal and visceral abdominal lymph nodes.
Parietal abdominal lymph nodes receive lymph from the lower limb through the common iliac lymph nodes. They are arranged as three chains: the left lumbar nodes surrounding the aorta, the right lumbar nodes surrounding the inferior vena cava and the intermediate lumbar nodes between the two blood vessels. Thus, they are often referred to as the aorticocaval lymph nodes. In addition, inferior diaphragmatic and inferior epigastric lymph nodes form part of the parietal abdominal lymph nodes.
