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

Figure 1

There is a slightly lobulated well-demarcated 1.4 × 1.7 × 1.2 cm intradural extramedullary mass lesion (blue arrow) in the spinal canal, anterior to the spinal cord at the level of C2-C3. There is mass effect with posterior displacement of the cord as well as cord edema. There is widening of the ventral subarachnoid space. It is homogeneously isointense on T1 and slightly heterogeneously hypointense on T2. Postcontrast imaging demonstrates avid diffusely homogenous enhancement.
