CTICasesBenign solitary fibrous tumor of the pleura
Imaging findings
CTA demonstrates a massive (19 cm), homogeneous, well-defined mass filling the left hemithorax, with its primary blood supply arising from the left internal mammary artery (LIMA) and an intercostal branch. Pathology confirmed a benign solitary fibrous tumor (SFT) of the pleura.
Key takeaways
Solitary fibrous tumors of the pleura are slow-growing mesenchymal tumors. Despite their large size, benign variants are typically homogeneous and lack high-grade features. Preoperative embolization of systemic feeding vessels (such as the LIMA) is helpful to reduce surgical bleeding risk.
