1 - While they travel together, the internal mammary veins, arteries and lymph nodes represent three distinct functional systems that are affected by a variety of diseases and should be assessed individually. A basic familiarity of normal anatomy and the spectrum of pathology is essential for accurate interpretation of chest CT. 2 - This image-rich educational exhibit will review the diverse pathology that can affect the internal mammary veins, arteries and lymph nodes including neoplastic, inflammatory/infectious, congenital, traumatic and iatrogenic conditions.

Outline: Normal anatomy (lymph nodes, arteries, veins) Lymphadenopathy - size criteria for enlargement; discuss exclusion from IASLC staging for lung cancer Reactive (infection) - empyema (bacterial, parasites, mediastinitis, other) Malignant (breast, lung/pleural; abdominal with review pathway of drainage from peritoneal cavity/liver) Arteries: -bypass graft (anatomy from subclavian, any variants?) -dilated - coarctation, interrupted aortic arch, BT shunt, unilateral vs bilateral -collateral supply to lungs (mycetoma, fibrosis) -traumatic pseudoaneurysm with active extravasation Veins: -dilated - collateral pathways SVC syndrome, varices -trauma -tumor -iatrogenic - catheter placement in internal mammary vein Conclusion
