Atypical case of posterior reversible encephalopathy syndrome related to late onset postpartum eclampsia

<jats:title>Abstract</jats:title> <jats:sec> <jats:title>Rationale:</jats:title> <jats:p>Eclampsia, an obstetric emergency frequently seen in pregnant or puerperal women, is a risk factor for posterior reversible encephalopathy syndrome (PRES). Most cases of eclampsia occur postpartum. We report a woman with PRES associated with eclampsia 10 weeks post-delivery, the latest onset ever reported.</jats:p> </jats:sec> <jats:sec> <jats:title>Patient concerns:</jats:title> <jats:p>A 23-year-old healthy woman presented headache and nausea 10 weeks after delivery. Two days later, she generalized tonic-clonic seizure. Her brain MRI presented the foci which is typical of PRES.</jats:p> </jats:sec> <jats:sec> <jats:title>Diagnosis:</jats:title> <jats:p>The patient was diagnosed as PRES associated with eclampsia.</jats:p> </jats:sec> <jats:sec> <jats:title>Interventions:</jats:title> <jats:p>The patient received levetiracetam and edaravone.</jats:p> </jats:sec> <jats:sec> <jats:title>Outcomes:</jats:title> <jats:p>Her clinical course was uneventful and she fully recovered without neurological complications</jats:p> </jats:sec> <jats:sec> <jats:title>Lessons:</jats:title> <jats:p>The possible diagnosis of late onset postpartum eclampsia, even weeks post-delivery, should be considered, since initiation of early treatment averts severe complications and decreases mortality. Sharing our experience may increase awareness of PRES induced by late-onset postpartum eclampsia.</jats:p> </jats:sec>
