BACKGROUND The presence of antibodies to the myelin oligodendrocyte glycoprotein (MOG) has been identified in about 40% of children with acute disseminated encephalomyelitis (ADEM). The objective of this report was to describe three fulminant cases of ADEM complicated by increased intracranial pressure associated with the presence of the anti-MOG antibodies. METHODS This is a retrospective case series. Informed consent was obtained from the concerned patients or caregivers. RESULTS High intracranial pressure associated with ADEM in the presence of MOG antibodies can result in cerebral edema, herniation, prolonged hospital stay (average intensive care unit stay: 22 days, average hospital stay: 50.6 days), and long-term disability. CONCLUSION Increased intracranial pressure complicating MOG antibody-related ADEM is a unique finding in our cases. This can complicate the clinical picture of ADEM and confers high morbidity. Long-term immunosuppression is warranted in selected cases with persistent seropositivity.
