Brown-Sequard syndrome associated with Horner’s syndrome following a penetrating drill bit injury to the cervical spine

Abstract We report a 41-year-old male who presented with a partial Brown-Sequard syndrome and Horner’s syndrome following a penetrating drill bit injury to his mid cervical spine. As the injury was not a complete hemisection of the spinal cord, the patient presented with ipsilateral motor deficit and hyperesthesia and diminished contralateral fine touch sensation; however, proprioception, vibration and temperature were all initially intact. A cervical CT and MRI scan showed a damaged spinal cord at the C5/6 level with posterior cord compression secondary to haematoma. A decompressive laminectomy and evacuation of the haematoma was performed. Over the following 5 days the patient’s right-sided motor deficit improved daily; however, he developed a contralateral deficit to pain and temperature upon wakening from the operation which did not resolve. The right-sided Horner’s syndrome also persisted.
