Preoperative sagittal (A) and axial (B) T2-weigthed MRI revealed a spinal cord herniation at the level of T 6/7 (read arrow) and disc herniation at the level of T 7/8 (blue arrow). Postoperative sagittal (C) and axial (D) follow-up T2-weigthed MRI after 3 months revealed the release of spinal cord herniation.

A magnetic resonance imaging of the spine revealed spinal cord displacement to the ventral location of the spinal canal at the level of T 6/7, a possible adhesion of the cord tissue to the upper part of the T 7 dorsal vertebral body, and a hyperintensity of the spinal cord in T2-weighted imaging at the same level (Figures 1A,B). In the follow-up after 3 months, the magnetic resonance image of the spinal axis showed good release of the spinal cord without reattachment (Figures 1C,D).
Preoperative sagittal and axial CT scan in a soft tissue window (A) and bone window (B,C) revealed a bone spur at the level T6/7 (red arrow) as a possible cause of spinal cord herniation.

A supplementary thin-sliced computed tomography of the spine revealed a bone spur at the level of T 6/7 (Figure 2).

Intraoperatively, the cranial and caudal ends of the right paramedian ventral dural defect were visualized (Figure 3).
