Study design: Case Report
Abstract: BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary arteriopathy associated with the NOTCH3 gene. Clinical manifestations include strokes, transient ischaemic events, psychiatric disturbances, dementia, and migraines. We report a case of a Thai man with a severe CADASIL phenotype who presented with recurrent seizures and acute ischaemic stroke and classic vascular risk factors. CASE PRESENTATION: A 50-year-old man with a history of mood disorder and progressive cognitive decline for 20 years as well as well-controlled diabetes mellitus and hypertension presented with recurrent generalized seizures and acute right-sided weakness. An MRI of the brain showed acute infarction of the left pons, a large number of cerebral microbleeds throughout the brain and white matter abnormalities without classic anterior temporal lobe lesions. Molecular genetic testing identified a homozygous pathologic variant, c.1672C > T (p. Arg558Cys), in the NOTCH3 gene. The diagnosis of CADASIL was confirmed. His clinical symptoms deteriorated, and he died of tracheobronchitis with secretion obstruction. CONCLUSION: This case raises awareness of an uncommon cause of acute ischaemic stroke in patients with classic vascular risk factors and emphasizes the need for a complete evaluation in cases with unexpected clinical presentation or unexpected diagnostic study results.
