Two recent clinical reports detail rare cases of postpartum eclampsia complicated by posterior reversible encephalopathy syndrome, highlighting how acute neurological symptoms like seizures, severe hypertension, and psychosis can develop in young mothers.
Posterior reversible encephalopathy syndrome remains an elusive clinical entity, first described in 1996 and previously known as reversible posterior leukoencephalopathy syndrome. Characterized by acute neurological symptoms including severe headaches, seizures, altered mental status, and visual disturbances, the condition is frequently linked to endothelial dysfunction states such as preeclampsia and eclampsia. While the exact incidence in the general population remains uncertain, neuroimaging frequently identifies the condition in obstetric patients experiencing eclampsia.
Adolescent Postpartum Eclampsia and Refractory Hypertension
A 16-year-old pregnant woman at 35.4 weeks of gestation arrived at the emergency department exhibiting marked proteinuria, headache, and elevated lactate dehydrogenase levels alongside fetal growth restriction and suspected placental abruption. Medical teams managed the presentation as preeclampsia with severe features. During the subsequent surgical delivery, clinicians observed a large retroplacental hematoma and a 40% placental abruption. Due to uterine atony refractory to massage and oxytocin, a B-Lynch hemostatic suture was performed, and the newborn was transferred to basic neonatal care while the mother entered postoperative monitoring in the pediatric intensive care unit.
Seventeen hours after the cesarean delivery, the adolescent suffered a generalized tonic-clonic seizure. A non-contrast head CT scan revealed bilateral frontal, parietal, and occipital cortico-subcortical hypodensities, while a subsequent brain MRI confirmed bilateral asymmetric cortical and subcortical hyperintense signal abnormalities consistent with vasogenic edema. Throughout her intensive care unit stay, the patient battled refractory hypertension that demanded intravenous sodium nitroprusside and prazosin, alongside levetiracetam for seizure prophylaxis.
Postpartum Psychosis and Emergency Hospital Presentation
A parallel case described by Elsevier involves an 18-year-old pregnant woman at 39.3 weeks from Cali, Colombia, with no relevant prior medical history. Admitted due to a premature rupture of membranes, she underwent a cesarean delivery for a breech-positioned fetus. Fourteen hours post-delivery, she reported an intense holocranial headache accompanied by phosphenes, quickly followed by a generalized tonic-clonic seizure. Laboratory tests indicated proteinuria and elevated lactate dehydrogenase levels, pointing toward eclampsia despite normal initial blood pressure readings.
The clinical picture escalated dramatically over the next day and a half. Thirty-six hours after symptom onset, her mean arterial pressure climbed, requiring intravenous labetalol and oral antihypertensives. Concurrently, the patient developed acute psychotic symptoms marked by anxiety, hallucinations, soliloquies, psychomotor agitation, and hetero-aggression, culminating in an attempt to jump from the fifth floor of the hospital. She suffered additional generalized tonic-clonic seizures controlled by benzodiazepines, magnesium sulfate, and phenytoin. Following comprehensive metabolic, infectious, immunological, and rheumatoid studies that yielded normal results, medical and psychiatric teams managed her care until her neurological and psychiatric manifestations fully resolved. A follow-up brain CT showed complete normalization, and she was discharged on day nine.
Pathophysiological Mechanisms and Diagnostic Challenges
The underlying mechanics connecting posterior reversible encephalopathy syndrome and related vascular anomalies continue to be debated across clinical literature.
Because syndromes like posterior reversible encephalopathy syndrome share clinical and radiological overlaps with conditions such as reversible cerebral vasoconstriction syndrome, timely neuroimaging remains vital. As medical awareness and diagnostic imaging availability expand, recognizing atypical presentations—such as postpartum psychosis or seizures—remains critical for preventing permanent neurological harm or fatal complications from ischemic stroke and intracranial hemorrhage.
