CTICasesThoracic Ewing Sarcoma
Imaging findings
Chest CT shows a giant, heterogeneous, hypervascular mass in the left hemithorax with internal necrosis. The mass causes marked mediastinal shift and severe extrinsic compression of the left pulmonary artery. Pathology confirmed Ewing sarcoma.
Key takeaways
Thoracic Ewing sarcoma (or PNET) typically presents in teenagers as a giant, hypervascular, necrotic chest wall or pleural-based mass that compresses rather than invades adjacent mediastinal structures.
