A case of NMDAR encephalitis treated in the third trimester - novel arterial spin labeling findings and a review of literature

초록

Diagnosis and treatment of anti-NMDAR encephalitis during pregnancy are challenging. We report a case of anti-NMDAR encephalitis in a 28-year-old, 24 weeks pregnant woman. Her brain magnetic resonance imaging was normal, but arterial spin labeling (ASL) showed increased cerebral blood flow in the right insula and temporal area. She was successfully treated with emergent cesarean section and immunotherapies including intravenous immunoglobulin, steroids, and rituximab. The newborn was healthy and she recovered fully. Early suspicion and proper management is important in treatment of anti-NMDAR encephalitis during pregnancy. ASL can help diagnosing anti-NMDAR encephalitis during pregnancy.
