Role of CECT abdomen in evaluation of abdominal lymph nodes in different abdominal pathologies: Does size of lymph nodes really matter?

Abstract

Many disease, neoplastic, infective, inflammatory, autoimmune result in abdominal lymphadenopathy. Because there is a complex pattern of intercommunications between regional groups of lymph nodes, it is usual for lymphadenopathy to involve several contiguous or even widely separated nodule chains. The abdominal lymph nodes are empirically divided into groups: 1. Retrocrural 2. Retroperitoneal 3. Porta hepatis 4. Gastrohepatic ligament 5. Celiac and superior meseneteric artery 6. Preaortic and paraaortic 7. Pancreaticoduodenal 8. Perisplenic 9. Periumbilical 10. Mesenteric Aims and Objectives 1. To evaluate lymph nodes in different abdominal pathologies i.e. group of lymphnodes involved, morphology, size etc. 2. To assess the size of lymph nodes in different abdominal pathologies.
