Figure 2:

(a) Coronal and (b) sagittal T1-weighted images demonstrating the diffusely infiltrating hyperintense tumor causing marked compression on the left and anterior spinal cord surfaces. Of notice the extraspinal extension through the left third and fourth foramina and the anterior component of the lesion located anteriorly to the third and fourth vertebral bodies. (c) Sagittal T2-weighted scan showing the inhomogeneous hypointensity of the lesion. (d) The paraspinal and the intra-extradural components of the tumor exhibited homogeneous gadolinium enhancement. (e) Postoperative T2-weighted image documented successful decompression of the spinal cord and debulking of the intraspinal component of the tumor. (f) Axial T1-weighted image after the administration of contrast showing considerable reduction of the paraspinal component of the solitary fibrous tumors/hemangiopericytomas following the four cycles of chemotherapy.
