PRES
Also written as: PRES — Posterior Reversible Encephalopathy Syndrome
A clinical-radiological syndrome characterized by reversible brain edema, typically affecting the posterior regions.
Full Definition
Posterior Reversible Encephalopathy Syndrome is a neurological condition seen in critically ill pediatric patients, often associated with hypertension, immunosuppressive therapy, or renal disease. The syndrome presents with altered mental status, seizures, and characteristic MRI findings of vasogenic edema predominantly in the posterior cerebral regions. Recognition is crucial as the condition is typically reversible with appropriate management of underlying causes.
Usage
Usage note: Always spell out on first use in patient documentation.
