Abstract

PRES is a clinic radiological syndrome characterized by neurologic findings with edema predominantly in the posterior region of the brain. Pathophysiology is not clear but the final problem is thought to be cerebral vasogenic edema. It usually occurs with seizures, unconsciousness, headache, visual abnormalities, nausea / vomiting and more rarely with hemiparesis or aphasia. MRI is vital for diagnosis. MRI findings are characterized by hyper intense signals in fluidattenuated inversion recovery sequences .PRES is usually reversible due to vasogenic edema. Therefore, PRES has a relatively good prognosis. MRI findings and clinical symptoms are reversible, especially if the syndrome is treated early and appropriately.
