It extends into paravertebral space through C3-C4, C4-C5 & C5-С6 widened intervertebral foramina on the left side, giving a dumbbell-shaped appearance. Large para vertebral component seen causing posterior displacement of vertebral artery with encasement of the vertebral artery at the place, however, flow void is maintained and no luminal narrowing seen. Marked spinal cord compression at these levels by the above mass lesion with right lateral deviation of the cord and intramedullary T2 W hyperintense cord signal abnormality at C3 & C4 levels.
The histopathological report suggestive of schwannoma (neurilemmoma).
