Many cases of left VCP related to cardiovascular pathologies have been documented. However, right VCP associated with cardiovocal (Ortner) syndrome is an atypical and rare presentation. A case of right VCP caused by a right aortic arch (RAA) and Kommerell diverticulum (KD), diagnosed on CT angiography, and its association with the variant course of the right RLN, is described.\nContribution:\u00a0This case report highlights the rarity of cardiovocal syndrome causing a right VCP and the association of a RAA with the variant course of the right RLN hooking around the RAA in place of the right subclavian artery.<\/jats:p>","DOI":"10.4102\/sajr.v30i1.3382","type":"journal-article","created":{"date-parts":[[2026,3,9]],"date-time":"2026-03-09T12:53:46Z","timestamp":1773060826000},"update-policy":"https:\/\/doi.org\/10.4102\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Atypical cardiovocal syndrome associated with right aortic arch and Kommerell diverticulum"],"prefix":"10.4102","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-1554-1223","authenticated-orcid":false,"given":"Chetna","family":"Mishra","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04gzb2213","id-type":"ROR","asserted-by":"publisher"}],"name":"University of Delhi"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-9387-0940","authenticated-orcid":false,"given":"Vikas","family":"Yadav","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04gzb2213","id-type":"ROR","asserted-by":"publisher"}],"name":"University of Delhi"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7338-4397","authenticated-orcid":false,"given":"Rama","family":"Anand","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04gzb2213","id-type":"ROR","asserted-by":"publisher"}],"name":"University of Delhi"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8020-6049","authenticated-orcid":false,"given":"Moazzam","family":"Mojahid","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04gzb2213","id-type":"ROR","asserted-by":"publisher"}],"name":"University of Delhi"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2580","published-online":{"date-parts":[[2026,3,12]]},"reference":[{"key":"ref0","doi-asserted-by":"crossref","unstructured":"Rizvi MM, Singh RB, Jain A, Sarkar A.
