CTICasesSVC Syndrome and Transpleural Collaterals
Imaging findings
Large infiltrating central mediastinal mass causing SVC syndrome, extensive chest wall collaterals, and hyper-perfusion in the peripheral middle lobe, likely representing systemic-to-pulmonary vein collateral circulation.
Key takeaways
Central venous obstruction can lead to significant collateral pathways, including systemic-to-pulmonary communication, which can cause dramatic peripheral enhancement patterns.
