In addition, increase in size is not always pathologic; some nodes are bigger than others normally (e.g compare jugulodigastric nodes to mesenteric nodes), and reactive nodes are a healthy response and do not imply pathology of the node itself. Most descriptive systems are based on a modification of Rouvière’s classification of lymph node groups. 9. These nodes are located in the AP window lateral to the ligamentum arteriosum. However, this criterion, being an absolute value, depends on lymph node location and has either low sensitivity or low specificity.
