Figure 13a. Axial diagrams show the main regional drainage pathways (black nodes) for malignant mesothelioma. E = esophagus. (a) Diagram shows the anterior scalene/supraclavicular nodes (ASSCN). ASM = anterior scalene muscle, LCCA = left common carotid artery, LJV = left internal jugular vein, RCCA = right common carotid artery, RJV = right internal jugular vein, Tr = trachea. (b) Diagram shows the extrapleural nodes (EPN), internal mammary nodes (IMN), lobar node (LN), 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, TD = thoracic duct. (c) Diagram shows the pericardial fat nodes (PCFN). Ao = aorta, CS = coronary sinus, ECF = epicardial fat, LV = left ventricle, PCF = pericardial fat, RA = right atrium, RV = right ventricle, TD = thoracic duct. (d) Diagram shows the anterior peridiaphragmatic nodes (APDN) and extrapleural nodes (EPN). Ao = aorta.
