Acute disseminated encephalomyelitis (ADEM) has been linked to immunizations, viral infections, and occasionally to arthropods stings. Its association with scorpion stings has not been described. A 29-year-old man, who after being stung by a scorpion presented right hemiparesis and language impairment. Brain MRI showed subcortical bihemispheric lesion characteristics of ADEM and a bigger one compatible with Baló concentric sclerosis (BCS). Patient was managed with steroids, showing complete clinical improvement. Magnetic resonance imaging (MRI) after 6 months showed cavitation of the bigger lesion with no new findings. In 2 years of follow-up, there is no clinical relapse or new lesions in MRI. Although cases of ADEM have been reported due to venom of chilopoda and hymenoptera, the scorpion sting can be considered as another new cause; this case being even more relevant due to present a Baló-like lesion in MRI.
