Magnetic resonance of the dorsal spine [sagittal acquisition - (a and d) T1-weighted images; (b and e) T2-weighted images; (c and f) SPIR (Selective partial inversion recover) T2-weighted images] demonstrating the spinal cord herniation (a-c) and the radiological result following surgical treatment (d-f)

T4 with a spastic paraparesis and bilateral (right greater than left) muscle atrophy. The MR revealed a ventral dural gap at the T4 level [Figure 1a-c].
Intraoperative photograph. (a) Here, the herniated spinal cord content is demonstrated (instrument tip to the right). (b) The dural defect (indicated by the instrument), the reduced spinal cord area, and the tapering of the spinal cord at the herniation level are shown

T4 laminectomy at which time the ventral dural gap was repaired (e.g. ventral dura mater defect repaired utilizing a 5-0 prolene suture to attach a muscle/fascia patch to the surrounding healthy dura mater) and the cord was reduced [Figure 2a] at surgery. The herniated cord appeared "violaceous/pale" in color and was hardened [Figure 2b].
