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.
