Posterior reversible encephalopathy (PRES) is a clinico radiological syndrome, which manifests itself by headaches, confusion, consciousness disorders or during a sudden rise in blood pressure but can be seen in other circumstances, such as during an immune reaction or a systemic infection. Its mechanism is explained by a lesion of the blood-brain barrier leading to a reversible vasogenic edema. The scarcity of sympathetic innervation of the posterior cerebral territories explains its usual localization. We report the case of an 18 years old girl who presented with generalized tonic-clonic seizures following a scorpion bite, which yielded to Diazepam. An emergency brain MRI was performed, showing bilateral and symmetrical signal abnormalities of the posterior cortico-subcortical territories and basal ganglia, compatible with an atypical PRES syndrome. The diagnosis of PRES syndrome complicating a scorpion bite was retained.
