Posterior Reversible Encephelopathy Syndrome in Post-Streptococcal Glomerulonephritis

Posterior reversible encephalopathy syndrome (PRES) is a recognized brain disorder most commonly associated with hypertension, toxemia of pregnancy, or the use of immunosuppressive agents. Its clinical features include headache, decreased alertness, confusion, diminished spontaneity of speech, seizures, vomiting, and abnormalities of visual perception like cortical blindness. Magnetic resonance imaging shows edematous lesions primarily involving the posterior supratentorial white matter. We describe a 14-year-old boy who developed neurological symptoms of PRES during the course of acute post-streptococcal glomerulonephritis (APSGN).
