Abstract

Solitary fibrous tumor is a rare mesenchymal tumor, most frequently located in the pleura. Other locations have been recently described in the literature including the mediastinum. Solitary fibrous tumor of the mediastinum affects both men and women with a peak in frequency in the fifth and sixth decade. Most often asymptomatic and of incidental discovery, this tumor is evoked by a mediastinal opacity on thoracic radiography or a mediastinal tissue mass on CT scan and confirmed by histological examination through transcutaneous CT-guided aspiration biopsy or after complete
surgical removal.
