Clinical case:

Patient of 20 years of age, without pathological antecedents, with term pregnancy, evolutionary norm. Who enters by exit of mucous plug, followed by premature rupture of membranes, so it is admitted for conduction of labor, however presents convulsive crisis, generalized clonic tonic. Advanced airway management is decided, and an emergency caesarean section is performed, obtaining a single live product, and the patient is admitted to the ICU. His toxemic profile was reported without alterations, his initial CT scan without structural alterations, and mechanical ventilation was removed twelve hours later. MRI is performed where subcortical right parieto-occipital hyperintensity is observed, being kept under surveillance and graduated to floor without complications.

Conclusions:

The treatment of PRES syndrome is focused on organic and metabolic supports and mainly on tension Figures. Not all are reversible, however, the pregnant patient is more frequent than present evolution without sequelae.
