X-ray of the spine showed prevertebral soft tissue swelling that was confirmed on the cervical spine (C/S) MR imaging [Figure 1], along with an anterior extra-axial space-occupying lesion extending from C1 to C4 level resulting in complete obstruction of cerebrospinal fluid (CSF) flow [Figure 2].
On admission emergency cervical MRI of this patient reveals severe CSF block (a) in upper cervical region due to compression and anterior hypersignal extra-dural mass from C1 to C4 on T2 weighted sagittal (b) and axial (c) views

Repeated cervical MRI 4 days after first MRI shows no previous mass in T2-weighted sagittal (a) and axial (b) views
