ENCEFALITIS LÍMBICA, HIPONATREMIA, SÍNDROME DE SECRECIÓN INADECUADA DE ADH, DEMENCIAResumen
La encefalitis límbica (EL) autoinmune es una afección neurológica infrecuente de curso subagudo con manifestaciones neuropsicológicas. Actualmente el tratamiento inmunoterápico agudo o de mantenimiento es dirigido según el anticuerpo neural acompañante y la presencia o ausencia de cáncer.
Presentamos el caso de una mujer de 52 años con hipotiroidismo autoinmune, síndrome de secreción inadecuada de hormona antidiurética (SIADH) e hiponatremia (hipoNa) persistente, con evolución progresiva de perdida de la memoria y crisis distónicas faciobraquiales (DFBC) a quien se le realiza un diagnóstico oportuno de encefalitis límbica.
Recibió tratamiento intravenoso combinado en base a corticoides e inmunoglobulina con buena respuesta y morbilidad mínima neuropsicológica.
El reconocimiento de esta patología permite un diagnóstico y tratamiento temprano, imprescindible para mejorar el pronóstico de estos pacientes.
