Limbic encephalitis in a child with ovarian teratoma and influenza B. Case report and critical review of the history of autoimmune anti-N-methyl-d-aspartate receptor encephalitis

Anti-CASPR2 myeloencephalitis with active replication of hepatitis B virus in the central nervous system: a case report

“…Some AE patients present tumors, such as ovarian teratoma in a patient with encephalitis involving antibodies against the N-methyl- d -aspartate receptor [ 6 ], and a thymoma in a patient with anti-caspr2 encephalitis [ 2 ]. Viral infection also appears capable of triggering AE: cases of encephalitis involving antibodies against the N -methyl- d -aspartate receptor have been linked to infection by herpex simplex virus, H1N1 influenza virus, influenza B virus, and severe acute respiratory syndrome coronavirus 2 [ 3 , 7 ]. Some patients have been reported to have chronic HBV infection as well as neurological disorders including acute disseminated encephalomyelitis, neuromyelitis optica spectrum disorders, and Guillain-Barré syndrome [ 4 ].…”
