AbstractWe report a case of Brown-Séquard syndrome and cervical CSF leakage caused by a knife injury. A 34-year-old man was involved in a fight and was stabbed on his occiput and back with a knife. Neurological examination on admission showed right hemiparesis, right hemihypesthesia and left hemihypalgesia, indicating Brown-Séquard syndrome. Furthermore, cerebrospinal fluid was leaking from the occipital stab wound. Head CT scan showed massive accumulation air in the subarachnoid space. Cervical MRI showed that the injury tract reached to the space between the occipital bone and the atlas. One week after admission, suboccipital craniectomy and duraplasty were performed because of continuous CSF leakage. Although, the CSF leakage recurred due to the wound infection, it disappeared naturally as the patient's general condition improved. Follow-up MRI studies demonstrated the cervical spinal lesion as hyperintensity on T2WI, which localized at the right side of the spinal cord. The patient's hemiparesis gradually improved and he underwent rehabilitation. Spinal cord injury due to a stab wound by a knife is rare in Japan. In this case, we suppose that the mechanism of spinal cord injury was due to direct injury by a knife avoiding the lateral corticospinal tract because his right hemiparesis obviously improved.
