(a) Neutral position MRI of cervical spine T2W image reveals mild focal atrophy of cervical cord at C6-C7 levels with loss of attachment between the posterior dural sac and subjacent lamina. (b) Flexion MRI of cervical spine T2W image reveals characteristic anterior displacement of the posterior wall of cervical dural canal reaching up to spinal cord. Prominent posterior epidural spaces with multiple flow voids suggestive of prominent venous plexus are present.
