Background and purpose: To report a unique case of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy manifesting as a progressive supranuclear palsy phenotype, thereby expanding its recognized presentations.
Methods: Review of the pertinent literature from MEDLINE, cross-referencing cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, progressive supranuclear palsy, and parkinsonism. Description of a 60-year-old woman who presented with a several year history of step-wise, progressive parkinsonism secondary to cerebral autosomal dominant arteriopathy.
Results: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy may present with a progressive supranuclear phenotype.
Conclusion: Parkinsonism, including a progressive supranuclear palsy phenotype, is one of a growing number of recognized ways that cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy may present.
