Posterior reversible encephalopathy syndrome (PRES) and reversible cerebral vasoconstriction (RCVS) are rare neurological disorders with complex physiopathology which is not yet fully understood. We present here the case of a 31-year-old woman with a bi-amniotic bi-chorial pregnancy who developed immediate postpartum eclampsia after vaginal delivery, associated with RCVS and PRES. Although post-partum is a well-known precipitating factors for these diseases, to our knowledge, there are only few similar cases reported with the association of these syndromes. Repeated MRI scans were instrumental in the final diagnosis of RCVS associated with PRES, allowing us to give the patient the appropriate treatment. These two syndromes have similar symptoms but may have different treatments, thus highlighting the importance of a correct diagnosis.
