Abstract

A 40-year-old Asian female presented with a 2-month history of right shoulder pain and right triceps weakness. MRI revealed an extramedullary, extradural, dumbbell-shaped spinal cord tumor with C6 to C7 iso- and hyperintensity on T1 and T2 weighted imaging, respectively. Histological examination revealed monomorphous spindle cells with a storiform pattern. Immunohistochemistry was positive for CD34, CD99, and negative for EMA, SMA, and S100; solitary fibrous tumor (SFT) was confirmed.

Figure

• 

  Fig. 1 Preoperative magnetic resonance images and computerized tomographic scan showing a dumbbell-shaped, extramedullary, extradural mass with homogenous enhancement at C6-7. A: Sagittal, T2-weighted image showing a hypointense mass behind C6 and C7 vertebral bodies. B: Sagittal, T1-weighted image showing isointense mass. C: Axial, T1-weighted-gadolinium-enhanced image showing a homogenously enhanced mass, located mainly in the extradural space with foraminal extension and partly in the intradural extramedullary space. D: Computerized tomographic scans showing enlarged, right C6-7 neural foramina.

• 

  Fig. 2 Pathological findings. A: Hematoxylin and eosin staining showing uniform spindle cells with storiform pattern. The tumor is composed of haphazardly arranged spindle cells with intervening hyaline stroma. Mitosis and necrosis are absent. B: Immunohistochemical staining showing CD34-positive spindle cells.
