BACKGROUND AND PURPOSE: Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is increasingly recognized in children. Some children have isolated disease while others relapse. The study evaluates clinical, demographic and imaging features children with positive anti-MOG antibodies comparing to previously reported findings and correlate patterns on MR imaging with a relapsing course in MOGAD.
MATERIAL AND METHODS: All pediatrics patients with serum anti-MOG antibodies were reviewed. Demographic, clinical, and imaging data were evaluated. Patients with a relapsing course were compared to those with a single event. We assessed initial MR images of the brain, orbits and spine obtained at the onset of clinical symptoms, whether performed at our institution or elsewhere.
RESULTS: Thirty patients were included, fourteen with a single event and sixteen with more than one clinical event. The mean age was 8.1 years, with a mean follow-up of 58 months (range of 0.67 to 238 months). The relapsing patients had a mean of 3.5 relapses (range 2-12). 55% of patients had long segment optic nerve lesions, 53% of patients had cortical or peripheral white matter lesions, and 46% of patients had thalamic lesions. 43% of patients had spinal cord lesions, with 39% involving the central cord and 26% with long segment involvement. The imaging features between the groups were not statistically significant.
CONCLUSION: There were no distinguishing features in relapsing versus non-relapsing patients. In the absence of any predictive characteristics for future relapse, patients should have regular clinical and imaging follow up.
