It mostly develops secondary to a destructive lesion involving the Guillain\u2013Mollaret pathway. The mostly reported destructive lesions causing hypertrophic olivary degeneration are stroke, trauma, tumors, neurosurgical interventions, and gamma knife treatment of brainstem cavernoma. It presents with symptomatic palatal tremor, and typically appears as an expansive nonenhancing nodular lesion that shows increased signal intensity on magnetic resonance imaging (MRI). The identification of hypertrophic olivary degeneration on MRI is of great importance as its MRI appearance is very similar to those of more severe pathologies, including tumors, infarction, demyelinating lesions, and infections. We present a case of hypertrophic olivary degeneration in a patient with a history of ischemic stroke two years before the development of palatal tremor.<\/jats:p>","DOI":"10.4103\/ijri.ijri_412_18","type":"journal-article","created":{"date-parts":[[2020,1,3]],"date-time":"2020-01-03T12:26:51Z","timestamp":1578054411000},"page":"435-437","source":"Crossref","is-referenced-by-count":4,"title":["Hypertrophic olivary degeneration: A case report"],"prefix":"10.1055","volume":"29","author":[{"given":"Meltem","family":"\u00d6zdemir","sequence":"additional","affiliation":[{"name":"Department of Radiology, D\u0131\u015fkap\u0131 Y\u0131ld\u0131r\u0131m Beyaz\u0131t Training and Research Hospital, University of Health Sciences, Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aynur","family":"Turan","sequence":"additional","affiliation":[{"name":"Department of Radiology, D\u0131\u015fkap\u0131 Y\u0131ld\u0131r\u0131m Beyaz\u0131t Training and Research Hospital, University of Health Sciences, Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rasime Pelin","family":"Kavak","sequence":"additional","affiliation":[{"name":"Department of Radiology, D\u0131\u015fkap\u0131 Y\u0131ld\u0131r\u0131m Beyaz\u0131t Training and Research Hospital, University of Health Sciences, Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alper","family":"Dilli","sequence":"additional","affiliation":[{"name":"Department of Radiology, D\u0131\u015fkap\u0131 Y\u0131ld\u0131r\u0131m Beyaz\u0131t Training and Research Hospital, University of Health Sciences, Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2021,7,21]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"302","DOI":"10.3389\/fneur.2017.00302","article-title":"Hypertrophic olivary degeneration and palatal or oculopalatal tremor","volume":"8","author":"C Tilikete","year":"2017","journal-title":"Front Neurol"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"8","DOI":"10.4103\/2156-7514.150454","article-title":"Hypertrophic olivary degeneration \u2013 A report of two cases","volume":"5","author":"R Sarawagi","year":"2015","journal-title":"J Clin Imaging Sci"},{"key":"ref3","first-page":"1073","article-title":"Hypertrophic olivary degeneration: Metaanalysis of the temporal evolution of MR findings","volume":"21","author":"M Goyal","year":"2000","journal-title":"AJNR Am J Neuroradiol"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"1252","DOI":"10.1093\/brain\/awh137","article-title":"Progressive ataxia and palatal tremor (PAPT): Clinical and MRI assessment with review of palatal tremors","volume":"127","author":"M Samuel","year":"2004","journal-title":"Brain"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"145","DOI":"10.1111\/j.1552-6569.2009.00461.x","article-title":"Diffusion tensor imaging of Guillain-Mollaret triangle in patients with hypertrophic olivary degeneration","volume":"21","author":"A Din\u00e7er","year":"2011","journal-title":"J Neuroimaging"},{"key":"ref6","doi-asserted-by":"crossref","first-page":"401","DOI":"10.4103\/0971-3026.143902","article-title":"MRI and MR tractography in bilateral hypertrophic olivary degeneration","volume":"24","author":"D Sen","year":"2014","journal-title":"Indian J Radiol Imaging"}],"container-title":["Indian Journal of Radiology and Imaging"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.4103\/ijri.IJRI_412_18.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,7,21]],"date-time":"2021-07-21T22:47:44Z","timestamp":1626907664000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.4103\/ijri.IJRI_412_18"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,10]]},"references-count":6,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2021,7,21]]},"published-print":{"date-parts":[[2019,10]]}},"URL":"https:\/\/doi.org\/10.4103\/ijri.ijri_412_18","archive":["Portico","CLOCKSS"],"relation":{},"ISSN":["0971-3026","1998-3808"],"issn-type":[{"value":"0971-3026","type":"print"},{"value":"1998-3808","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,10]]}}}
