This is a rare example of a single arterial supply to brain structures on both sides of the midline. Occlusion of the artery of Percheron results in bilateral medial thalamic infarction, which is manifest clinically as gaze paresis, cognitive disturbance and altered consciousness. The presentation can mimic subarachnoid haemorrhage, drug intoxication, encephalitis and other inflammatory or infective conditions. The presentation is similar to the \u2018top of the basilar syndrome\u2019 and early recognition should prompt further investigation for underlying stroke aetiologies and consideration can be given to thrombolysis if vascular occlusion can be confirmed.<\/jats:p>","DOI":"10.1136\/bcr-2012-007205","type":"journal-article","created":{"date-parts":[[2012,11,19]],"date-time":"2012-11-19T11:35:44Z","timestamp":1353324944000},"page":"bcr2012007205","source":"Crossref","is-referenced-by-count":4,"title":["Occlusion of the artery of Percheron: an unusual cause of bilateral stroke"],"prefix":"10.1136","volume":"2012","author":[{"given":"Clare","family":"Anderson","sequence":"first","affiliation":[{"name":"Radiology Department, City Hospitals Sunderland NHS Foundation Trust, Sunderland, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"O'Brien","sequence":"additional","affiliation":[{"name":"Care of the Elderly Department, City Hospitals Sunderland NHS Foundation Trust, Sunderland, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2012,11,19]]},"reference":[{"key":"2025082707174213000_2012.nov16_1.bcr2012007205.1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.d4277"},{"key":"2025082707174213000_2012.nov16_1.bcr2012007205.2","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000179677.84785.63"},{"key":"2025082707174213000_2012.nov16_1.bcr2012007205.3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jstrokecerebrovasdis.2009.07.003"},{"key":"2025082707174213000_2012.nov16_1.bcr2012007205.4","doi-asserted-by":"publisher","DOI":"10.1007\/BF00315956"},{"key":"2025082707174213000_2012.nov16_1.bcr2012007205.5","first-page":"309","article-title":"Arteries of the human thalamus.
