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

Figure 6

Axial NECT of cervical spine (Figure 6(a)) demonstrates a calcified well-marginated lesion (green arrow) within posterior aspect of central canal at C1 level. On sagittal T2WI (Figure 6(b)) and sagittal postgadolinium (Figure 6(c)) MR images, this extramedullary intradural lesion (orange arrows) is noted to be T2 hypointense and mildly rim enhancing, respectively, causing effacement of posterior thecal sac and abutment of cervical spinal cord at the level of posterior arch of C1. The imaging findings favor a calcified meningioma.
