Solitary Fibrous Tumor/Hemangiopericytomas (SFT/HPC) is a rare tumor that arises from pericapillary cells. It is commonly found in musculoskeletal system and skin, but rarely found in the central nerve system, extremely rare in the spinal canal. Because of its rarity of this tumor, its clinical and radiographic characteristics of features and clinical manifestations have not been extensively. We report a rare case of Solitary Fibrous Tumor/Hemangiopericytoma (SFT/HPC) that developed in the thoracic vertebral intradural extramedullary region. A 50-year-old man experienced numbness in the left lower limb and weakness in the right lower limb from 2 months prior to initial visit to our hospital. MRI revealed that an intradural extramedullary tumor with strongly enhancement compressed the spinal cord toward the left on 7th thoracic vertebral level. Due to exhibit dural tail sign, clinically a diagnosis of meningioma was possible and removal of the tumor was performed. The histopathological diagnosis was SFT/HPC. The gait disturbance was improved postoperatively. SFT/HPC tumors arising in central nerve system mainly develop in intracranial region and SFT/ HPC tumors occurring in the spinal canal, especially intradural region, are extremely rare. It is difficult to differentiate from meningioma clinically. Surgical excision is recommended as the first choice for treatment of this tumor, but SFT/HPC tumors are more likely to recur locally and to metastasize even over an extended time, so long-term observation is necessary.
