Imaging findings
Chest CT shows a large, well-defined pleural-based mass in the left lower hemithorax with a large pedicle (stalk). Large feeding vessels from the left lower lobe are seen supplying the mass, which also contains chunky, dystrophic calcification. A small pleural effusion is present. Histopathological examination confirmed a solitary fibrous tumor of the pleura with some malignant features.
Key takeaways
Solitary fibrous tumors of the pleura are mesenchymal neoplasms that typically arise from the visceral pleura and are often pedunculated, receiving their blood supply via a prominent vascular pedicle from pulmonary or systemic vessels. Although most are benign, malignant features can be present. Findings of a pleural effusion, heterogeneous enhancement, and dystrophic calcification can suggest a higher likelihood of malignancy.
