摘要

Superior vena cava (SVC) syndrome is a common complication of lung cancer, including both non-small cell and small cell lung cancers. The formation of collateral circulation can reduce clinical symptoms, such as shortness of breath, a puffy face, and neck and arm swelling. Here, we report a case of SVC syndrome in a 70-year-old woman, a never-smoker, who presented with right neck and right arm numbness for 1 month. Right upper lobe lung cancer with partial compression of the SVC was diagnosed. Chest computed tomography revealed a rare collateral circulation pathway, i.e., the phrenic venous pathway. Collateral circulation was observed during the follow-up period.
