Figure 1: (a and b) Sagittal and axial T2-weighted MR images of the upper thoracic spine reveal anterior displacement, flattening and a kink (large arrows) of the spinal cord posterior to the T3 vertebral body. The signal intensity of the herniated spinal cord segment parallels that of the remaining thoracic spinal cord. Note the enlarged cerebrospinal fluid space posterior to the spinal cord at the level of herniation. Artifacts due to turbulent CSF flow can be appreciated in the widened CSF space dorsal to the cord (small arrow in b)
