Imaging findings
Chest radiograph reveals a circumscribed mass at the right anterior cardiophrenic angle. CT shows a fairly homogeneous mass with large feeding vessels and a prominent pedicle originating from the mediastinal pleura, abutting the right middle lobe. This finding was asymptomatic and consistent with a fibrous tumor of the pleura.
Key takeaways
Solitary fibrous tumors of the pleura (SFTP) are typically benign mesenchymal tumors that can arise from either the visceral or parietal pleura (including mediastinal pleura). They can present as circumscribed masses, often at the cardiophrenic angle, and may have large feeding vessels and a visible pedicle. Although they can be mobile, their appearance on CT with characteristic vascularity and a pedicle helps differentiate them from other cardiophrenic angle masses such as fat pads, Morgagni hernias, or pericardial cysts. Surgical resection is the treatment of choice.
