[Weston-Hurst syndrome. A case report and literature review]

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.

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.

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.
