case_images: Preoperative MRI thoracic spine. (a) Sagittal view; arrow pointing to the level of the spinal cord herniation at T7-8, (b) Axial view at the level of the spinal cord herniation T7-8. MRI thoracic spine, T2-weighted sequence.

case_images: The thoracic MRI showed a ventral thecal sac irregularity with accompanying distortion of the ventral cord, consistent with "tethering;" cervical and lumbar studies were unremarkable [Figure 1].
case_images: CT myelogram. (a) Sagittal view; arrow pointing to the level of the spinal cord herniation at T7-8, (b) Axial view at the level of the spinal cord herniation at T7-8. CT myelogram.

case_images: The CT myelogram was suggestive of ventral dural tear and spinal cord herniation at the T7-8 levels and a diffuse ventral subdural fluid collection extending from T1 to T10 [Figure 2].

case_images: We performed a T7-T8 laminectomy and unilateral facetectomy with removal of the right T7 pedicle and transverse process, exposing the T7-8 nerve roots [Figure 3].
case_images: Postoperative MRI thoracic spine. (a) Sagittal view; arrow pointing to the level of the prior spinal cord herniation at T7-8, (b) Axial view at the level of the spinal cord herniation T7-8.

case_images: On repeat, MRI at 4 months postoperatively demonstrates postsurgical changes with a well-circumscribed right paraspinal fluid collection with minimal mass effect on the spinal cord [Figure 4].
