1- To describe the clinical , physiopathology and imaging features of EXTRAPLEURAL Solitary Fibrous Tumors (SFT) based in 9 cases diagnosed and treated at our center. 2-To show the imaging and histological correlation. 3-To make a review of the literature.

1-Introduction about SFT.What we have to know? SFT is a rare spindle-cell neoplasm of mesenquimal origin that were first described in the pleura. Is an uncommon tumor occurring in the intracranial and extra cranial head and neck regions. We reported nine cases in in the head&neck and spine regions. Correct diagnosis could be challenging as some other lesions can mimick these tumors. 2. Physiopathology and natural history of SFT and hemangioperytomas.Immunohistochemical study. 3-MR and CT features.Evaluation of location,margins,MR signal intensity,CT density,internal architecture,pattern of enanchement.Darker signal intensity on T2-weighted images represents a firmer fibrous tumor composed of abundant collageneous stroma. 4-Differential diagnosis.Mimicks lesions. 5-Comments about recurrences and metastasis. Most SFT are bening but exist local recurrences and invasive growth pattern and metastasis(lung,lives,bones). 5. Summary
