Brain magnetic resonance imaging (MRI) showed a new active MS lesion involving the basal ganglia on the left side (Figure 1(a)). Intravenous steroid treatment resulted in rapid regression of this paroxysmal kinesigenic dyskinesia (PKD)-like hyperkinetic movement disorder. The patient became asymptomatic within 3 months. PKD is characterized by recurrent uni- or bilateral choreoathetosis and usually represents an autosomal dominant inherited disorder caused by PRRT2 gene mutations. As in the present case, a PKD-like phenotype may be associated with MS relapses in presumably genetic negative cases.<\/jats:p>","DOI":"10.1177\/1352458517702535","type":"journal-article","created":{"date-parts":[[2017,4,11]],"date-time":"2017-04-11T05:13:20Z","timestamp":1491887600000},"page":"1795-1797","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Paroxysmal kinesigenic dyskinesia\u2013like phenotype in multiple sclerosis"],"prefix":"10.1177","volume":"23","author":[{"given":"Roxana","family":"Pop","sequence":"first","affiliation":[{"name":"Department of Neurology and Internal Medicine, Kantonsspital Olten, Olten, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Kipfer","sequence":"additional","affiliation":[{"name":"Department of Neurology and Internal Medicine, Kantonsspital Olten, Olten, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,4,11]]},"reference":[{"key":"bibr1-1352458517702535","doi-asserted-by":"publisher","DOI":"10.1136\/jmedgenet-2012-101406"},{"key":"bibr2-1352458517702535","doi-asserted-by":"publisher","DOI":"10.1177\/1756285608095119"},{"key":"bibr3-1352458517702535","doi-asserted-by":"publisher","DOI":"10.3892\/etm.2014.2155"},{"key":"bibr4-1352458517702535","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awv317"},{"key":"bibr5-1352458517702535","doi-asserted-by":"publisher","DOI":"10.1016\/j.jns.2013.02.007"}],"container-title":["Multiple Sclerosis Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1352458517702535","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1352458517702535","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1352458517702535","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T03:50:08Z","timestamp":1777693808000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1352458517702535"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,4,11]]},"references-count":5,"journal-issue":{"issue":"13","published-print":{"date-parts":[[2017,11]]}},"alternative-id":["10.1177\/1352458517702535"],"URL":"https:\/\/doi.org\/10.1177\/1352458517702535","relation":{},"ISSN":["1352-4585","1477-0970"],"issn-type":[{"value":"1352-4585","type":"print"},{"value":"1477-0970","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,4,11]]}}}
