Acute Disseminated Encephalomyelitis and Acute Hemorrhagic Encephalomyelitis

Atypical acute disseminated encephalomyelitis with systemic inflammation after a first dose of AztraZaneca COVID-19 vaccine. A case report

“…Also, the MRI evolution of the lesions is atypical for several reasons: the sub-acute evolution (longer than 3 months), the discordance between brain and spinal cord lesions in terms of how they evolved and their aspects, and the limited resolution on the last MRI after 7 months of follow-up. As some studies have described, some lesions could take up to 18 months to disappear ( 15 ) or persisted on follow-up imaging ( 16 ). We did have the information of the MRI evolution from only 3 previously reported cases as shown in Table 2 : one with a complete resolution in 1 month ( 4 ) and the other two with a partial resolution at follow-up of 30 and 66d ( 6 , 11 ).…”
