Anti-NMDA receptor encephalitis is a severe but treatable autoimmune disease of the CNS. However, the use of immunotherapy and long-term outcomes have yet to be defined for this disease. We describe a case of an 18-year-old male diagnosed with anti-NMDAR encephalitis not associated with tumor, which did not respond to initial treatment with immunoglobulin, followed by corticosteroids, cyclophosphamide and evolved with significant clinical improvement after a prolonged course of plasmapheresis. Although it is not possible to affirm the good outcome was due solely to the prolonged plasmapheresis regimen, recently published data shows that improvement may take weeks or months to occur. This case discloses another therapeutic possibility for patients with refractory disease who fail to respond to recommended first-line and second-line therapy.

Introduction: Anti-N-methyl-D-aspartate receptor (NMDA-R) encephalitis is a neuropsychiatric disorder with additional psychiatric features caused by NMDA-R immunoglobulin G (IgG) antibodies in cerebrospinal fluid (CSF). This report presents the follow-up of a patient in whom we assumed mild NMDA-R encephalitis in the first psychotic episode.
Case Study: A patient with a prior episode of an acute polymorphic psychotic syndrome relapsed five and a half years later following a severe COVID-19 infection.

Background: Pediatric N-methyl-d-aspartate receptor (NMDAR) encephalitis (pNMDARE) is characterized by severe neuropsychiatric symptoms and prolonged hospitalization and recovery. Early pNMDARE diagnosis is complicated by neuropsychiatric mimickers requiring strong clinical suspicion to escalate to the required lumbar puncture (LP), delaying diagnosis and treatment. Since autonomic dysfunction is a cardinal feature of pNMDARE, we hypothesized that early vital signs serve as a potential noninvasive biomarker to screen for appropriate escalation of pNMDARE evaluation.

This case report highlights a rare association between anti-NMDAR encephalitis and meningioma, where the patient developed typical autoimmune encephalitis symptoms shortly after tumor resection. Unlike the well-established link with ovarian teratomas, meningioma-associated cases may involve indirect immune mechanisms, such as molecular mimicry or bystander activation, rather than direct antigen exposure. The findings emphasize the need for postoperative autoimmune screening in neurosurgical patients with unexplained neuropsychiatric symptoms.

Background: Imaging, particularly multimodal magnetic resonance imaging (MRI), serves as an essential auxiliary examination for diagnosing autoimmune encephalitis (AE). The diversity of autoantibodies complicates the imaging presentation of AE, exhibiting both common and individual features across different subtypes of AE. Currently, there is a lack of comprehensive studies on the imaging features of different subtypes of AE.
