He was found to have diffuse large B-cell lymphoma encasing the left internal carotid artery but not impeding blood flow. The syncopal episodes resolved after his first cycle of chemotherapy. Recurrent syncope in non-cardiac lymphomas and other head and neck masses is exceedingly rare and may be due to reflex syncope prompted by carotid baroreceptor activation. There are 11 previously described cases of recurrent syncope associated with non-cardiac lymphoma. In all cases, lymphadenopathy abutting the carotid artery was present and the syncopal episodes resolved with treatment. Our case illustrates that malignancy should be considered in patients with unexplained recurrent syncope.<\/jats:p>","DOI":"10.1136\/bcr-2021-244881","type":"journal-article","created":{"date-parts":[[2021,12,30]],"date-time":"2021-12-30T08:34:37Z","timestamp":1640853277000},"page":"e244881","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Syncope caused by lymphomatous encasement of the internal carotid artery"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1811-317X","authenticated-orcid":false,"given":"Ellery","family":"Altshuler","sequence":"first","affiliation":[{"name":"Internal Medicine, University of Florida College of Medicine, Gainesville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3028-8618","authenticated-orcid":false,"given":"Mahmoud","family":"Aryan","sequence":"additional","affiliation":[{"name":"Internal Medicine, University of Florida College of Medicine, Gainesville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jess","family":"Delaune","sequence":"additional","affiliation":[{"name":"Hematology and Oncology, College of Medicine, University of Florida, Gainesville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"Lynch","sequence":"additional","affiliation":[{"name":"Hematology and Oncology, College of Medicine, University of Florida, Gainesville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,12,30]]},"reference":[{"key":"2025082707531917000_14.12.e244881.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2017.03.003"},{"key":"2025082707531917000_14.12.e244881.2","doi-asserted-by":"crossref","first-page":"595","DOI":"10.1038\/s41416-019-0692-2","article-title":"Syncope as a sign of occult cancers: a population-based cohort study","volume":"122","author":"Lorenzen","year":"2020","journal-title":"Br J Cancer"},{"key":"2025082707531917000_14.12.e244881.3","doi-asserted-by":"crossref","first-page":"649","DOI":"10.1016\/S0300-8932(01)76369-5","article-title":"[Syncope due to parapharyngeal space lesions syncope-syndrome]","volume":"54","author":"C\u00f3rdoba L\u00f3pez","year":"2001","journal-title":"Rev Esp Cardiol"},{"key":"2025082707531917000_14.12.e244881.4","doi-asserted-by":"crossref","first-page":"497???503","DOI":"10.1288\/00005537-199404000-00018","article-title":"Carotid sinus syncope in head and neck cancer","volume":"104","author":"Bauer","year":"1994","journal-title":"Laryngoscope"},{"key":"2025082707531917000_14.12.e244881.5","doi-asserted-by":"crossref","first-page":"31","DOI":"10.1186\/1746-160X-8-31","article-title":"Carotid sinus syndrome as the presenting symptom of cystadenolymphoma","volume":"8","author":"Noroozi","year":"2012","journal-title":"Head Face Med"},{"key":"2025082707531917000_14.12.e244881.6","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/euq409"},{"key":"2025082707531917000_14.12.e244881.7","unstructured":"Armstrong M , Kerndt CC , Moore RA .
