A CASE OF COMBINED CENTRAL AND PERIPHERAL DEMYELINATION IN A PATIENT WITH PEDIATRIC MULTIPLE SCLEROSIS AFTER SARS-COV-2 VACCINATION

Abstract

We present a case of combined central and peripheral demyelination in a patient with pediatric multiple sclerosis after the first dose of ChAdOx1-S (Chimpanzee Adenovirus Oxford 1) vaccination. The patient presented with ascending flaccid quadriparesis with respiratory failure that required mechanical ventilation. The lumbar puncture revealed albuminocytological dissociation, was negative for presence of JCV (John Cunningham Virus) in the CSF (Cerebrospinal Fluid) and ruled out other infections. A few days later he developed anisocoria and multiple new enlarging acute demyelinating lesions in the brain MRI (Magnetic Resonance Imaging). He was treated with intravenous immunoglobulin, corticosteroids and plasma exchange with gradual improvement. All other diseases were excluded via MR Spectroscopy, MR Angiography and serum and CSF laboratory investigations. Seven months later, the patient is under intense physiotherapy and is improving every day.
