Background. Stroke in young patients (<50 years old) represents a diagnosis and therapeutic challenge, given the multitude of etiologies and mimics of the disease. Pregnant women have a higher risk of stroke during the entire pregnancy, especially in the postpartum p eriod. Case report. We present the case of a young women of 35 years old, admitted to the neuroemergencies department, with previous transient amaurosis, single episode of complex motor seizures the week before admission, moderate right sided hemiparesis, and temporal spatial disorientation. Anamnesis reveals an emergency c section 12 days before hospitalization at 36 weeks of pregnancy. Past medical history unremarkable. Admission neurological state: awake, alert, disoriented in time, and space. Intact cranial nerves. Diminished strenght in the right upper and lower limbs 2/5 points; hypertonus and brisk deep tendon reflexes on the right; bilateral Babinski sign; mild hemihypoalgesia on the right side; temporal and spatial disorientation, cognitive dec line (MMSE 15p). No meningeal signs. To exclude a possible posterior circulation ischemic stroke, a brain computed tomography was performed showing some diffuse occipital lobe lesions suggestive for encephalitis. Further investigation by 3T brain MRI showe d diffuse, bilateral, white matter lesions of possible inflammatory or toxic metabolic etiology. Posterior Reversible Encephalopathy Syndrome (PRES) diagnosis was established and targeted treatment performed. Two weeks later we noticed complete resolution of the motor deficit (patient walking alone without support), the patient was alert, oriented in time, space and herself, the cognitive function improved (MMSE 25 p) with home discharge. Normal follow up MRI (1 month) was obtained. Conclusions. Stroke sho uld be excluded in post partum women given the higher incidence in this group of population. PRES syndrome is a benign stroke mimic that should be suspected in the appropriate clinical and imagistic context for correct management of the pathology.
