This Case Study describes a 80-year-old patient with lower-body parkinsonism who was diagnosed with vascular parkinsonism on the basis of clinical and neuroimaging findings, but whose gait and, to a lesser extent, cognitive impairments improved following external lumbar drainage. Postmortem neuropathology confirmed a diagnosis of normal pressure hydrocephalus.
