FLAMES is a new clinico-radiological sub entity of myelin oligodendrocyte glycoprotein (MOG) antibody associated disease (MOGAD). FLAMES is characterized by fluid attenuated inversion recovery (FLAIR) imaging showing hyperintense cortical lesions, in MOG associated Encephalitis with Seizures. MOGAD usually presents with optic neuritis, myelitis or acute disseminated encephalomyelitis and such rare focal cortical encephalitis like presentation can be mistaken as due to viral aetiology. FLAMES can present with unilateral or bilateral cortical encephalitis and we report a case where magnetic resonance angiography, susceptibility weighted imaging and perfusion studies were done and the utility of these additional imaging markers in diagnosing FLAMES is discussed.

Objective: To clarify the clinical features of recurrent myelin oligodendrocyte glycoprotein antibody-associated cortical encephalitis (MOGCE) in adults.
Methods: We present an adult case of recurrent MOGCE and summarize the clinical symptoms, imaging findings, treatment and prognosis of this phenotype as per a systematic review of the literature.
Results: We identified 9 adult patients with recurrent MOGCE.

Background: Chronic neurologic deficits from traumatic brain injury (TBI) and subsequent infectious encephalitis are poorly characterized.
Methods: Using TriNetX database we queried patients 18 years or older with a confirmed diagnosis of encephalitis between 2016 and 2024. Patient cohorts included those with a diagnosis of TBI at least one month before encephalitis ( = 1,038), those with a diagnosis of a TBI anytime before encephalitis ( = 1,886), and those with encephalitis but no TBI, ( = 45,210; = 45,215).

The Fc receptor (FcRn) inhibitors can ameliorate autoimmune conditions such as myasthenia gravis through a rapid and specific clearance of serum IgG levels, and they also have potential for future use in a wider variety of antibody-mediated autoimmune diseases. Some patients with therapy-refractory autoimmune encephalitis (AE) continue to be unresponsive to initial and secondary treatment regimens. A 32-year-old male presented with predominant psychiatric symptoms and seizures, along with imaging evidence indicating multifocal cerebral cortical involvement.

After decades of inactivity throughout the Americas, western equine encephalitis virus (WEEV) recently re-emerged in South America, causing a large-scale outbreak in humans and horses. WEEV binds protocadherin 10 (PCDH10) as a receptor; however, nonpathogenic strains no longer bind human or equine PCDH10 but retain the ability to bind avian receptors. Highly virulent WEEV strains can also bind the very low-density lipoprotein receptor (VLDLR) and apolipoprotein E receptor 2 (ApoER2) as alternative receptors.

To summarise the clinical characteristics, radiological features, treatments and prognosis of patients with myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD) overlapped with NMDA receptor (NMDAR) encephalitis. We retrospectively analysed patients who exhibited dual positivity for MOG antibodies and NMDAR antibodies in serum/CSF from Jan 2018 to Jun 2023. Ten patients with MOGAD and NMDAR encephalitis were enrolled.
