Introduction
Posterior reversible encephalopathy syndrome (PRES) is identified on
magnetic resonance (MR) imaging by posterior predominant white and gray
matter lesions. The common clinical features are headache, seizures, and
visual loss, often in the setting of renal failure, accelerated
hypertension and following administration of immunosuppressive drugs. It
is widely accepted that the mechanism of PRES is the generation of
vasogenic edema caused by failure of cerebral autoregulation and the
production of cytotoxic edema due to ischemia. PRES secondary to spinal
disease is very rare. Only a few reports show PRES occurred in patients
with spinal epidural hematoma. Here, we report a case of clinical and
imaging findings about PRES associated with spinal epidural hematoma.
