Spinal SFTs are typically intradural extramedullary lesions that mimic common tumors such as meningiomas or schwannomas. Our case highlights how an atypical spinal SFT was diagnosed on magnetic resonance (MR) and successfully resected.<\/jats:p>\n<\/jats:sec>\n\nCase Description: <\/jats:title>\nA 55-year-old female with a history of chronic nocturnal low back pain and multiple falls presented with urinary incontinence alone. The spinal MR imaging (MRI) revealed an intradural, extramedullary, lobulated contrast-enhancing lesion at T7. The lesion was resected utilizing a hemi-laminectomy\/tubular retractor. Postoperatively, the patient recovered normal function, and the MR confirmed gross total tumor excision. The histopathology confirmed a solitary fibrous tumor (central nervous system [CNS] World Health Organization grade 1), composed of spindle cells in a collagenous stroma with thin-walled, staghorn-like vessels. Immunohistochemistry showed focal vimentin positivity and negative STAT6 staining, supporting a lowgrade SFT diagnosis. Eighteen months later, the MRI showed enhancement at the surgical site but without a clear mass; an open biopsy confirmed normal inflammatory changes, but no tumor recurrence.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nSpinal SFTs are exceedingly rare neoplasms that can mimic more common spinal tumors, and early diagnosis with surgical biopsy and immunohistochemical confirmation is essential to ensure accurate management.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_402_2025","type":"journal-article","created":{"date-parts":[[2025,7,4]],"date-time":"2025-07-04T09:26:47Z","timestamp":1751621207000},"page":"270","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Solitary
