This 58-year-old female complained about temperature changes and hyperpathy in her left leg for the past 12 months. On the right side, the sensibility was different but not normal. The strength in her left leg was diminished. These complaints ascended over time, initially starting at the foot and developing further to the groin at the time of presentation.\nNeurological examination revealed only a paretic quadriceps femoris muscle on the left side. Vital sensibility was disturbed on the left side below T10. The plantar reflexes on both sides were indifferent.\nAn MRI revealed a herniation of the SC at T8 (Figure ).\nDuring surgery, a laminectomy on T8 and T7 was performed. The dentate ligaments were transected. While gently mobilizing the SC from the left to the right, a large defect in the ventral dura was observed. The same maneuver at the right side revealed a fixed SC with the defect. After transection of some adhesions, a tumor-like extension of the SC was seen (Figure ) and was finally mobilized completely intradurally. To prevent re-herniation, an artificial graft was gently placed in front of the SC covering the defect and fixated laterally to the dural sleeve. Throughout the entire surgery, MEPs, SSEPs, and D-waves were monitored. Changes were not noticed. Post-operatively, the patient did not notice any new complaints.
A 76-year-old female presented with progressive onset difficulty in walking, leg weakness, and gait ataxia. On clinical exam, she had a sensory level T9 and T8-9 myelopathy was suspected. Lab parameters were within normal limits. There was no history of trauma. MRI thoracic spine demonstrated acute ventral kink in the thoracic spinal cord at T2-3 level [].
