Discussion
PRES was first described in 1996 and is a well-known syndrome that typically presents with a headache, seizures and visual disturbance [1]. The most common cause of PRES is sever hypertension, renal failure, immunosuppressant therapy, chemo therapy, eclampsia and autoimmune disorder. In connection with spinal disease, though several reports show PRES associated with autonomic dysreflexia in spinal cord injury patients [2-4], only a few reports with spinal epidural hematoma. PRES due to spinal epidural hematoma has occurred such rarity with 2 cases reported previously [5, 6] (Table1). Among them, only 2 cases caused by spontaneous spinal epidural hematoma including our case. Case No.2 is postoperative case. Spontaneous spinal epidural hematoma itself could not lead to PRES, so several risk factors are connected.
