CTICasesMalignant Solitary Fibrous Tumor
Imaging findings
Chest radiograph reveals a very large mass with associated pleural fluid, calcification, and mediastinal shift. CT further characterizes it as a very large, highly vascular, heterogeneous tumor with internal necrosis and extensive calcifications, demonstrating parasitism from adjacent vessels.
Key takeaways
Malignant solitary fibrous tumor is a rare, aggressive tumor that can present as a large, vascular mass in the chest, often with internal necrosis and calcifications. Histological diagnosis is crucial, and the STAT6 marker is considered predictive for this entity.
