Posterior reversible encephalopathy syndrome: Pattern on ¹⁸F-fluorodeoxyglucose positron emission tomography-computed tomography correlated with magnetic resonance imaging in pediatric hypertensive encephalopathy

Posterior reversible encephalopathy syndrome (PRES) is characterized clinically by headache, seizures, vomiting, altered mental status, and blurred vision. However, with overlapping and atypical clinical symptoms, PRES becomes a diagnostic challenge. We describe the imaging findings of PRES in magnetic resonance imaging and¹⁸F-fluorodeoxyglucose positron emission tomography-computed tomography in an 11-year-old child who presented with features of hypertensive encephalopathy.
