Imaging findings
Chest radiograph shows extensive opacity in the basal right hemithorax. CT reveals a large, heterogeneous, very vascular lesion displacing lung, in contact with the hemidiaphragm. Multiple other concerning lesions are seen in the left lower lung lobe and near the major fissure, suggesting metastasis. Pathology confirmed a malignant fibrous tumor with features consistent with a malignant solitary fibrous tumor.
Key takeaways
Malignant solitary fibrous tumors can be large, heterogeneous, and vascular. Unlike their benign counterparts, they can be infiltrative and metastasize, appearing as additional nodules in other lung regions. Careful inspection for multifocal disease is crucial.
