# Posterior Reversible Encephalopathy Syndrome in a Late Postpartum Patient With a Rare Complication of Subarachnoid Hemorrhage

## TL;DR

A rare case of a postpartum patient with PRES and subarachnoid hemorrhage is reported, emphasizing the need for early recognition to improve outcomes.

## Contribution

This case report highlights a rare complication of PRES with subarachnoid hemorrhage in a postpartum patient.

## Key findings

- Neuroimaging revealed findings consistent with PRES and subarachnoid hemorrhage in a 10-day postpartum patient.
- The case underscores the importance of considering PRES in postpartum patients with headache and hypertension.
- Early recognition of PRES can help reduce morbidity and mortality in postpartum women.

## Abstract

Posterior reversible encephalopathy syndrome (PRES) is considered a neuroclinical syndrome of headache, confusion, visual changes, and seizures associated with neuroimaging findings of posterior cerebral white matter edema. Although the incidence of the syndrome is largely unknown, this condition is becoming increasingly recognized. The prognosis is generally good with most symptoms resolving within one week and lesions on imaging resolving in two weeks. Death and significant neurological disability have been reported but are relatively rare. In this report, we present a 10-day postpartum patient with an atypical history of headache and seizure-like activity. Neuroimaging revealed findings consistent with PRES as well as a rare complication of subarachnoid hemorrhage. This case highlights the importance of clinicians considering preeclampsia/eclampsia-induced PRES when encountering a postpartum patient with headache and hypertension to further reduce morbidity and mortality in this patient population.
