Fatal Acute Disseminated Encephalomyelitis Post-COVID-19 Vaccination: A Rare Case Report.

ABSTRACT

Acute disseminated encephalomyelitis (ADEM) is a disease of the brain and spinal cord that is an immune-mediated inflammatory and demyelinating disorder, which is commonly preceded by an infection. Some reports have also shown the association of acute demyelination of the central nervous system (CNS) with vaccination. Primarily, the involvement of the white matter of the cerebral hemispheres, brain stem, and spinal cord is observed. Such lesions should be considered as the differentials of ADEM. We would like to report a case of a 77-year-old female who was of post-COVID-19 vaccination status and presented to us with altered sensorium with imaging revealing acute demyelination.
