His neurological examination revealed he was oriented only to himself, and aforementioned movements of his left arm and leg. CT head demonstrated old infarcts in his right aspect of his pons and basal ganglia. Cerebrospinal fluid analysis was unremarkable. He initially had a normal blood glucose with an elevated anion gap and elevated creatine kinase. Brain MRI showed a small lacunar-type ischaemic infarct within the anteromedial aspect of the right cerebral peduncle, which localised to his haemiballism. To prevent worsening rhabdomyolysis associated with his haemiballism, the primary team initiated both tetrabenazine and diazepam. His movements improved after 1\u2009week of medication therapy. This report discusses a thorough workup for this movement disorder and when to intervene for this distressing condition.<\/jats:p>","DOI":"10.1136\/bcr-2020-240439","type":"journal-article","created":{"date-parts":[[2021,6,4]],"date-time":"2021-06-04T11:06:44Z","timestamp":1622804804000},"page":"e240439","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Haemiballism\/haemichorea: an atypical presentation of ischaemic stroke"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3313-4833","authenticated-orcid":false,"given":"Raman","family":"Nohria","sequence":"first","affiliation":[{"name":"Department of Family Medicine and Community Health, Duke University School of Medicine, Durham, North Carolina, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stacey","family":"Bennett","sequence":"additional","affiliation":[{"name":"Department of Neurology, Duke University Health System, Durham, North Carolina, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasmin Ali","family":"O'Keefe","sequence":"additional","affiliation":[{"name":"Department of Neurology, Duke University Health System, Durham, North Carolina, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,6,4]]},"reference":[{"doi-asserted-by":"publisher","key":"2025082709550804000_14.6.e240439.1","DOI":"10.1136\/jnnp.2003.011874"},{"doi-asserted-by":"publisher","key":"2025082709550804000_14.6.e240439.2","DOI":"10.1016\/S1474-4422(06)70494-X"},{"key":"2025082709550804000_14.6.e240439.3","doi-asserted-by":"crossref","first-page":"725","DOI":"10.1007\/s00415-004-0412-5","article-title":"Hemichorea after stroke: Clinical-radiological correlation","volume":"251","author":"Chung","year":"2004","journal-title":"J Neurol"},{"doi-asserted-by":"publisher","key":"2025082709550804000_14.6.e240439.4","DOI":"10.1016\/j.parkreldis.2011.08.015"},{"key":"2025082709550804000_14.6.e240439.5","doi-asserted-by":"crossref","first-page":"2187","DOI":"10.1212\/WNL.0000000000002741","article-title":"Network localization of hemichorea-hemiballismus","volume":"86","author":"Laganiere","year":"2016","journal-title":"Neurology"},{"doi-asserted-by":"publisher","key":"2025082709550804000_14.6.e240439.6","DOI":"10.1016\/S1474-4422(03)00554-4"},{"key":"2025082709550804000_14.6.e240439.7","doi-asserted-by":"crossref","DOI":"10.1007\/s11910-016-0676-z","article-title":"Alien hand syndrome","volume":"16","author":"Hassan","year":"2016","journal-title":"Curr Neurol Neurosci Rep"},{"doi-asserted-by":"publisher","key":"2025082709550804000_14.6.e240439.8","DOI":"10.1016\/S0022-510X(96)00290-0"},{"doi-asserted-by":"publisher","key":"2025082709550804000_14.6.e240439.9","DOI":"10.1161\/01.STR.0000022810.76115.C0"},{"key":"2025082709550804000_14.6.e240439.10","article-title":"Post-Stroke hemichorea: observation based study of 15 cases","volume":"51","author":"Parees","year":"2010","journal-title":"Rev Neurol"},{"key":"2025082709550804000_14.6.e240439.11","doi-asserted-by":"crossref","first-page":"2240","DOI":"10.1111\/j.1532-5415.2010.03111.x","article-title":"Thalamotomy for postapoplectic hemiballistic chorea in older adults","volume":"58","author":"Astradsson","year":"2010","journal-title":"J Am Geriatr Soc"},{"key":"2025082709550804000_14.6.e240439.12","doi-asserted-by":"crossref","DOI":"10.1007\/s11940-018-0529-y","article-title":"An update on the treatment of chorea","volume":"20","author":"Feinstein","year":"2018","journal-title":"Curr Treat Options Neurol"},{"unstructured":"LiverTox: Clinical and Research Information on Drug-Induced Liver Injury [Internet].
