Delayed diagnosis of posterior reversible encephalopathy syndrome (PRES) in a parturient with preeclampsia after inadvertent dural puncture

SummaryPosterior reversible encephalopathy syndrome is a rare complication generally associated with headache and acute changes in blood pressure. We present a case of posterior reversible encephalopathy syndrome where diagnosis was delayed because the patient also had preeclampsia and an inadvertent dural puncture, both associated with headache. The clinical challenge and the need for prompt diagnosis and treatment are emphasized.
