Binswanger disease (BD) involves injuries to the brain small vessels, resulting to gradually progressive subcortical ischemia. This disorder manifests with dementia, gait abnormalities, upper motor signs and parkinsonism, and presents as extensive, confluent, bilateral cerebral white matter hyperintensities in the MRI. Cases of BD typically manifests with vascular risk factors, such as hypertension and multiple strokes. We report a unique case of a Filipino patient whom we have diagnosed with BD presenting with no cardinal signs of parkinsonism, but with generalized choreiform movement disorder and without a history of hypertension and symptomatic strokes. To our knowledge, this is the first report presenting an adult patient with subcortical leukoaraiosis of Binswanger type associated with a hyperkinetic movement disorder.
