Abstract

|
A benign fibrous histiocytoma (BFH) is one of the fibrohistiocytic groups of soft-tissue tumors for which spinal involvement is extremely rare. To the best of our knowledge, most spine-originating BFHs are bone tumors. We report the first case of BFH occurring in the intraspinal extradural space on the lumbar spine. A 66-year-old female presented with severe claudication symptom. The preoperative magnetic resonance images showed a huge intraspinal, extradural, thecal-sac-compressing soft-tissue tumor that extended along the right L5 root to the neural foramen. The tumor was a relatively well-marginated, inhomogeneous soft-tissue mass with some fluid-containing cystic portions that were well enhanced by the gadolinium contrast dye. After a total facectectomy, the tumor was removed completely. The patient had a good neurological recovery without complications, and no recurrence was noted at the 6-month follow-up.
