Cervical MRI and CT. In the first and second row sagittal and parasagittal images of the cervical spine in T2 (a), T1 (b) and T1 with contrast enhancement (c) are shown. There is a vertebral tumor infiltration of the fifth and sixth vertebra with a small invasion into the spinal canal (arrow). Larger tumor masses are found in the right lateral paravertebral space (second row). The tumor is hyperintens in T2 (a , arrowheads ), hypointens in T1 and is partially contrast enhancing (arrowhead) with central non-enhancing parts ( arrow in c). Remarkably the tumor grows through the intervertebral foramina in an hour glass pattern ( last row, a) like a schwannoma even with enlargement of the osseous canal ( arrow in b, axial CT). The infiltrated vertebrae are only slightly hyperdens compared to the normal vertebrae ( arrowheads in c).
