Figure 9c. Axial diagrams show the main intrathoracic drainage pathways (black nodes) for lymphoma. E = esophagus, TD = thoracic duct. (a) Diagram shows the internal mammary/retromanubrial nodes (IMRMN), left bronchomediastinal trunk node (LBMTN), left paratracheal node (LPTN), preaortocarotid node (PACN), periesophageal/posterior mediastinum nodes (PEPMN), right brachiocephalic angle node (RBCAN), right phrenic node (RPN), and right paratracheal nodes (RPTN). LBCV = left brachiocephalic vein, LCCA = left common carotid artery, LSCA = left subclavian artery, RBCA = right brachiocephalic artery, RBCV = right brachiocephalic vein, Tr = trachea. (b) Diagram shows the internal mammary nodes (IMN), left phrenic node (LPN), periesophageal/posterior mediastinum nodes (PEPMN), right phrenic node (RPN), and right paratracheal nodes (RPTN). AA = aortic arch, LBCV = left brachiocephalic vein, RBCV = right brachiocephalic vein, Tr = trachea. (c) Diagram shows the extrapleural nodes (EPN), internal mammary nodes (IMN), lobar node (LN), left phrenic node (LPN), periesophageal/posterior mediastinum nodes (PEPMN), subcarinal node (SCN), and segmental node (SN). AA = ascending aorta, Ao = aorta, LMB = left main bronchus, PA = pulmonary artery, RMB = right main bronchus, RPA = right pulmonary artery, SVC = superior vena cava. (d) Diagram shows the pericardial fat nodes (PCFN) and periesophageal/posterior mediastinum nodes (PEPMN). Ao = aorta, CS = coronary sinus, ECF = epicardial fat, LV = left ventricle, PCF = pericardial fat, RA = right atrium, RV = right ventricle. (e) Diagram shows the anterior peridiaphragmatic nodes (APDN), extrapleural nodes (EPN), gastrohepatic ligament/celiac nodes (GHLCN), and periesophageal/posterior mediastinum nodes (PEPMN). Ao = aorta.
