Recurrent Anti-NMDAR Encephalitis Necessitating Oophorectomy in an Adolescent Patient: A Case Report

Abstract

Conclusion: This case of A-NMDAR encephalitis presented with many atypical features including neuropsychiatric presenting symptoms, bilateral teratomas, and severe recurrence of disease. While imaging is the recommended modality for investigation of etiology, no teratoma was identified on the second presentation, leading to an ethical and clinical conundrum in this adolescent patient. More research is needed to investigate other diagnostic methods for A-NMDAR encephalitis without distinct teratoma on imaging in female patients.
