Figure 4: A 76-year-old female who presented with progressive onset difficulty in walking, leg weakness, and gait ataxia. (a) Sagittal and (b) Axial T2-weighted images of the thoracic spine demonstrating anterior cord displacement (“C” shaped kink) of the spinal cord with an associated kink at T4-5 level representing anterior spinal cord herniation (Yellow arrows). Posterior to the kink, CSF pulsation artifacts are seen in the posterior subarachnoid space (White arrows). (c) Sagittal T2-weighted image of the thoracic spine demonstrating a focal swelling with small intramedullary T2 hyperintensity is seen in the spinal cord just proximal to the kink representing a focal syrinx (Red arrow).
