We reported a case of a 30-year-old multipara who was admitted at 37 weeks of gestation for induction of labour due to preeclampsia. After postpartum, the patient developed severe hypertension, eclamptic fits, confusion and cortical blindness. The patient was treated in the intensive care unit with antihypertensive drugs, calcium-channel antagonists, anticonvulsants and anti-edematous agents. Nineteen days later, there was a complete clinical improvement, except for a left homonymous hemianopia which remained. A head MRI showed that most of the lesions in the bilateral subcortical areas of the parietal, temporal and frontal lobes observed in previous images had disappeared, with the exception of the left occipital lobe lesions, which were significantly reduced. A neurological follow-up at 18 months found no permanent neurological abnormalities, except for the left homonymous hemianopia. Diagnosis of cortical blindness associated with posterior reversible encephalopathy syndrome is based on the presence of clinical features of acute neurologic compromise, abnormal neuroimaging, and nearly complete reversibility of findings after timely treatment. Further research should focus on the development of more effective therapeutic strategies for this condition.
