Overview

Case report reveals transient gallium uptake in an 11-year-old girl with anti-NMDA receptor encephalitis, suggesting limited diagnostic utility.

Key Points

  • To report a pediatric case of anti-NMDA receptor encephalitis with atypical symptoms and transient gallium uptake.
  • Case report of an 11-year-old girl with behavioral changes and neurological symptoms.
  • Used gallium scintigraphy, cerebrospinal fluid analysis, MRI, and SPECT scans for diagnosis and follow-up.
  • Administered high-dose intravenous methylprednisolone and immunoglobulin.
  • Identified transient gallium uptake in the left ilium without tumor evidence.
  • Patient showed neurological and psychiatric improvement after treatment, returning to baseline activities after one year.
  • Follow-up gallium scintigraphy showed resolution of abnormal uptake.
