Solitary Fibrous Tumor of the Ischiorectal Fossa : CT and MRI Findings

Solitary fibrous tumor (SFT) is a mesenchymal cell origin that usually occur in the pleura, but the presence of these tumors are currently reported in a variety of extrapleural sites, including retroperitoneum (1-6). Because of the rarity of SFTs, information on the imaging features is sparse, and the radiologic features of SFT occurred in the ischiorectal fossa have been rarely reported. In this case, we describe the CT and MRI findings in a case of a SFT that involved in the ischiorectal fossa. Case Report
