A Difficult Diagnosis And Challenging Management Of An Aggressive Case Of Aquaporin 4 Negative Nmosd.

Neuromyelitis optica spectrum disorders can be challenging to diagnose and manage. There is considerable potential long-term morbidity but this can be avoided by appropriate treatment. Here we present one such case that is interesting as well as instructive.

Post-COVID-19 Encephalitis With Claustrum Sign Responsive to Immunomodulation.

We describe a case of encephalitis following coronavirus disease 2019 (COVID-19) in a six-and-a-half-year-old girl who presented with acute onset confusion and jerky movements of the limbs. The patient was unvaccinated for COVID-19. Subsequent magnetic resonance imaging revealed a bilateral "claustrum sign" on T2 and fluid-attenuated inversion recovery (FLAIR) images and electroencephalogram reported moderate diffuse encephalopathy.
