Patient's dynamic cervical spine MRI. Neutral position T1 post-contrast cervical spine MRI, sagittal image (A) and axial image at level of C6 (B) demonstrates mild asymmetric narrowing of the lower left cervical spinal cord (white arrow). Flexion T1 post-contrast cervical spine MRI, sagittal image (C) and axial image at level of C6 (D) demonstrates increased left-sided narrowing of the lower cervical spinal cord (white arrow) and exuberant enhancement of the dorsal venous plexus (black arrow), not observed on neutral views.
