Resumen
Introducción: la encefalomielitis aguda diseminada es una enfermedad autoinmune y desmielinizante. Es rara en el adulto. Cuenta con tres variantes principales. Una de ellas es el síndrome de Weston Hurst, también conocido como leucoencefalitis hemorrágica aguda. El objetivo fue compartir la experiencia en el abordaje diagnóstico y terapéutico de esta rara enfermedad, así como hacer una revisión de la bibliografía actual, a fin de colaborar con el conocimiento de esta.
Caso clínico: mujer de 27 años con cuadro de infección respiratoria viral 2 semanas previas al desarrollo de síndrome neurológico caracterizado por parestesias, déficit motor, estatus epiléptico y encefalopatía aguda, el cual progresó a estado de coma y evidenció en resonancia magnética lesiones difusas hemorrágicas en sustancia blanca cerebral con desmielinización y edema periférico. Se inició tratamiento con esteroides por 5 días con mejora de síntomas, aunque persistió el déficit motor y sensitivo.
Conclusión: la encefalomielitis aguda diseminada y la variante hemorrágica de esta son entidades raras, con una importante gama de diagnóstico diferencial, que deben ser identificadas y tratadas de forma rápida para evitar su letal o incapacitante desenlace.
Abstract
Background: Acute disseminated encephalomyelitis is an autoimmune and demyelinating disease. It is rare in adults. It has 3 main variants. One of them is Weston-Hurst syndrome, also called acute hemorrhagic leukoencephalitis. The objective was to share the experience in the diagnostic and therapeutic approach of this rare disease, as well as make a review of the current bibliography, in order to collaborate in the knowledge of this disease.
Clinical case: 27-year-old woman, with a viral respiratory infection 2 weeks prior to the development of a neurological syndrome characterized by paresthesia, motor deficit, status epilepticus and acute encephalopathy, progressing rapidly to coma, with evidence in MRI of diffuse hemorrhagic lesions in cerebral white matter with demyelination and peripheral edema. It was administered steroid treatment for 5 days, with improvement of symptoms, but with motor and sensory deficits persisting.
Conclusion: Acute disseminated encephalomyelitis and its variants are rare entities, with an important range of differential diagnosis, which must be identified and quickly treated to avoid their lethal or disabling outcome.
