Posterior reversible encephalopathy (PRE) is a clinico-radiologic syndrome that may be due to a variety of pathologies, combining reversible central nervous system damage with typical encephalic imaging. There is a great variability in the clinical presentation of this syndrome and imaging aspects are sometimes atypical. RPE is an unusual neurological complication occurring during pregnancy or postpartum, especially in the context of preeclampsia, in which vasogenic oedema due to rupture of the hemato-encephalic barrier seems to be the main actor. Magnetic resonance imaging frequently shows a distinctive parieto-occipital pattern with a symmetrical distribution of changes reflecting vasogenic edema.

We report the observation of a 24-year-old primiparous patient with generalized convulsions associated with a hypertensive episode at 33 weeks of amenorrhea. An adapted and early management usually allows to prevent the occurrence of irreversible sequelae.
