She had been diagnosed with normal pressure hydrocephalus (NPH) and underwent ventriculoperitoneal shunt (VPS) placement 1 year prior. Before VPS placement, brain imaging showed ventriculomegaly and chronic infarction of the right putamen and claustrum. A lumbar drain trial resulted in modest improvement of gait dysfunction. She underwent VPS placement for suspected NPH, but her symptoms remained unchanged. Examination revealed mild cognitive impairment, left-sided and lower body predominant parkinsonism, as well as disproportionately prominent postural instability. Gait analysis showed increased gait variability, reduced velocity and shortened step length bilaterally. Motor and gait abnormalities did not change after administration of levodopa. Her symptoms have remained stable for up to 52 months since symptom onset. We postulate that the infarction affecting the right putamen and claustrum could have led to a higher-level gait disorder mimicking NPH.<\/jats:p>","DOI":"10.1136\/bcr-2024-259957","type":"journal-article","created":{"date-parts":[[2024,8,19]],"date-time":"2024-08-19T12:00:39Z","timestamp":1724068839000},"page":"e259957","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Right putamen and claustrum infarction mimicking normal pressure hydrocephalus"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8450-7121","authenticated-orcid":false,"given":"Natalia","family":"Chunga","sequence":"first","affiliation":[{"name":"Department of Neurology, University of Rochester, Rochester, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyra","family":"Curtis","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of Rochester, Rochester, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Colleen B","family":"Tomcik","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of Rochester, Rochester, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9766-6252","authenticated-orcid":false,"given":"Karlo J.","family":"Lizarraga","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of Rochester, Rochester, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,8,19]]},"reference":[{"key":"2025082712235247000_17.8.e259957.1","doi-asserted-by":"crossref","first-page":"717","DOI":"10.1055\/s-0041-1726355","article-title":"Approach to the Patient with Gait Disturbance","volume":"41","author":"Tarolli","year":"2021","journal-title":"Semin Neurol"},{"key":"2025082712235247000_17.8.e259957.2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.25046"},{"key":"2025082712235247000_17.8.e259957.3","doi-asserted-by":"publisher","DOI":"10.1001\/archneurpsyc.1942.02290060069004"},{"key":"2025082712235247000_17.8.e259957.4","doi-asserted-by":"publisher","DOI":"10.2176\/nmc.st.2020-0292"},{"key":"2025082712235247000_17.8.e259957.5","unstructured":"Shumway-Cook A , Woollacott MH .
