Posterior reversible encephalopathy syndrome (PRES) is a neurological complication linked to preeclampsia and eclampsia. This study compared the clinical and radiological features of PRES in patients with these conditions. This retrospective single-center cohort study from 2010 to 2024 included patients diagnosed with preeclampsia and eclampsia who underwent MRI due to neurological symptoms. Two radiologists, blinded to the clinical data, re-evaluated the MRIs twice. PRES cases were assessed based on the sites and patterns of involvement. Maternal and perinatal outcomes, along with laboratory characteristics, were reviewed through medical records. The study included 157 patients with preeclampsia and eclampsia who underwent MRI for neurological symptoms. PRES was diagnosed in 55 patients (35.0%), with a higher incidence of eclampsia (64.71%) compared to preeclampsia (20.75%). Patients with PRES were younger, had lower gravidity and parity, and were at an earlier gestational age than those with normal MRI findings. The parietal and occipital regions were the most affected in both preeclampsia and eclampsia patients with PRES. Parietal lobe and bilateral involvement were more common in the eclampsia group. Atypical involvement, including brainstem and cerebellar lesions, was observed in both groups. These findings suggest that eclampsia may represent a neurological manifestation of PRES.
