Abstract

Solitary fibrous tumor is rare benign mesenchymal neoplasm. The spinal solitary fibrous tumor is extremely rare. The authors experienced a case of intramedullary solitary fibrous tumor of cervicothoracic spinal cord in a 48-year-old man with right lower extremity sensory disturbance. Spinal MRI showed intradural mass lesion in the level of C7-T1, the margin between the spinal cord and tumor was not clear on MRI. A Left unilateral laminectomy and mass removal was performed. Intra operative finding, the tumor boundary was unclear from spinal cord and it had intramedullary and extramedullary portion. After surgery, patient had good recovery and had uneventful prognosis. Follow up spinal MRI showed no recurrence of tumor.

  Fig. 1 Preoperative axial (A and B) sagittal (C) MRIs demonstrating a left-sided intra-dural spinal cord tumor at the level of C7-T1. The tumor is homogenously enhanced after gadolinium injection. The tumor margin is unclear to spinal cord.

  Fig. 2 Intraoperative photograph (A) showing the tumor strongly adherent to pia mater and arising within the spinal cord, without clear margin. Photomicrographs of the specimen showing a proliferation of predominantly spindle-shape cells and intracellular collagen deposition (B : HE stain, ×40, C : HE stain ×400), and immune-histochemical staining revealing strong, diffuse positive for CD34 (D).

  Fig. 3 Postoperative photographs axial (A), sagittal (B) MRI images demonstrate partial removal after 2 weeks after surgery. At 6 months after operation, axial (C), sagittal (D) MRI showing no evidence of local recurrence.
