Extraosseous Intradural Chondrosarcoma of the Cervical Spine: A Case Report with Brief Review of Literature

Figure 8

Axial T2WI (Figure 8(a)), axial postgadolinium (Figure 8(b)), and coronal postgadolinium (Figure 8(c)) demonstrate a well-defined extramedullary heterogeneously enhancing T2 hyperintense lobulated lesion representing a schwannoma (green arrow) extending along the left C2 nerve root in this patient with neurofibromatosis type 2 (NF2). This lesion causes effacement of left lateral thecal space at C1-C2 level and abuts the cervical spinal cord on the left, which is demonstrated on Figures 8(a) and 8(b). There is widening of left C1-C2 neural foramen (pink arrow) by this lesion. Additional multiple intracranial meningioma (blue arrows) are also identified on coronal postgadolinium image (Figure 8(c)) in this patient with NF2.
