Intradural-extramedullary solitary fibrous tumor of the thoracic spine: A case report.

Spinal solitary fibrous tumors are extremely rare neoplasms and of those, intradural extramedullary location is even rarer. A 64-year-old male presented to the emergency department with worsening right leg pain over 1 month. Whole spine magnetic resonance imaging revealed a well-circumscribed mass with low T1 and markedly low T2 signal intensity at the level of T1-2. Spine computed tomography showed no evidence of calcification or acute hemorrhage. Surgical removal was performed and the final diagnosis was intradural extramedullary solitary fibrous tumor.
