Within minutes of arrival in the post-anaesthesia care unit, he developed intermittent involuntary motor episodes characterised by retrocollis, axial hyperextension and decorticate-like posturing. He remained alert and oriented throughout, and neuroimaging and laboratory studies were unremarkable. The patient later reported a similar experience after a previous anaesthetic involving propofol. This case highlights the importance of recognising propofol-induced opisthotonos as a rare but distinct clinical entity that may be mistaken for seizure or stroke.<\/jats:p>","DOI":"10.1136\/bcr-2025-270690","type":"journal-article","created":{"date-parts":[[2026,7,10]],"date-time":"2026-07-10T11:10:15Z","timestamp":1783681815000},"page":"e270690","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Propofol-induced opisthotonos in the post-anaesthesia care unit"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4521-3993","authenticated-orcid":false,"given":"Evan","family":"Shorr","sequence":"first","affiliation":[{"name":"Anesthesiology, Perioperative Care & Pain Medicine, NYU Grossman School of Medicine, New York, New York, USA"},{"name":"Anesthesiology, Perioperative Care & Pain Medicine, Bellevue Hospital Center, New York, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-0053-1593","authenticated-orcid":false,"given":"Laura","family":"Scholtz","sequence":"additional","affiliation":[{"name":"Neurology, NYU Grossman School of Medicine, New York, New York, USA"},{"name":"Bellevue Hospital Center, New York, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7755-2984","authenticated-orcid":false,"given":"Gabriel","family":"Soto Arzon","sequence":"additional","affiliation":[{"name":"NYU Grossman School of Medicine, New York, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7000-8620","authenticated-orcid":false,"given":"Kenneth","family":"Sutin","sequence":"additional","affiliation":[{"name":"Anesthesiology, Perioperative Care & Pain Medicine, NYU Grossman School of Medicine, New York, New York, USA"},{"name":"Anesthesiology, Perioperative Care & Pain Medicine, Bellevue Hospital Center, New York, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,7,10]]},"reference":[{"key":"2026071004100770000_19.7.e270690.1","first-page":"S72","article-title":"Molecular targets underlying general anaesthesia","volume":"147 Suppl 1","author":"Franks","year":"2006","journal-title":"Br J Pharmacol"},{"key":"2026071004100770000_19.7.e270690.2","unstructured":"Shahade A , De Jesus O .
