Objective:

To report a case of a pediatric patient with encephalitis and bronchopneumonia associated with MOG-IgG, highlighting the importance of MOG-IgG testing in similar cases.

Key Findings:
  • The patient tested positive for serum MOG-IgG despite negative infection results.
  • MOG-IgG testing is crucial in children with encephalitis and bronchopneumonia.
Interpretation:

This case underscores the potential for MOG-IgG-associated disorders to present with symptoms resembling infections, necessitating thorough testing.

Limitations:
  • Single case study limits generalizability.
  • Lack of long-term follow-up data on the patient's recovery.
Conclusion:

This case provides insights into atypical presentations of MOGAD in children and emphasizes the need for MOG-IgG testing in similar clinical scenarios.
