CTICasesSolitary Fibrous Tumor of the Pleura (Large Mass)
Imaging findings
Chest radiographs show a large pleural effusion and a consolidation-like density. CT reveals a very large, inhomogeneous pleural mass associated with a large pleural effusion. A calcified blood vessel is seen supplying the mass. Sagittal CT shows the mass hanging from the bottom of the right lower lobe, extending into the pleural space.
Key takeaways
Solitary fibrous tumors of the pleura often arise from the visceral pleura, with the bottom of the lower lobe being a favored location. They grow slowly and can reach massive sizes. Features like significant inhomogeneity and associated pleural effusion are more typical for malignant variants of solitary fibrous tumors, requiring resection and complete pathology to differentiate. Inflammatory myofibroblastic tumor (IMT) is another differential diagnosis for a large pleural mass.
