Primary intraspinal fibrosarcoma.

Fibrosarcomas of dura mater are very rare tumors representing only 0.5% of all central nervous system sarcomas. A higher incidence of dural fibrosarcomas has been reported in patients with neurofibromatosis. We present a case of spinal dura mater fibrosarcoma in a patient without neurofibromatosis. The diagnostic and therapeutic strategy in the clinical management is discussed.
