Common carotid bifurcation may have rare variations like separate origins of left internal and external carotid arteries from aortic arch, or bifurcation of common carotid artery within thoracic cavity. Intrathoracic carotid bifurcation is a rare variation with limited number of cases reported. The occurrence of a low carotid bifurcation seems to be embryologically related to the persistence of the ductus caroticus. Additionally, intrathoracic carotid bifurcation can be accompanied by findings of Klippel-Feil syndrome. Herein, we present imaging findings of an incidentally detected intrathoracic left common carotid artery bifurcation in a pediatric patient accompanied by fusion of the cervical vertebrae and ribs.eninfo:eu-repo/semantics/closedAccessCommon carotid arteryLow bifurcationKlippel-Feil syndromeVertebra fusionRib fusionThoracic bifurcationArchAnatomy & morphologyRadiology, nuclear medicine & medical imagingSurgeryCarotid artery, commonCervical vertebraeChildFemaleHumansIncidental findingsKlippel-feil syndromeRadiography, thoracicRibsTomography, x-ray computedArticle0005195969000082-s2.0-8507403334341141542431531710Anatomy & morphologyRadiology, nuclear medicine & medical imagingSurgeryExternal Carotid Artery; Thyroid Cartilage; ArteriesAortic archArticleBronchiectasisCarotid artery anomalyCase reportChildClinical articleComputer assisted tomographyContrast enhancementFemaleHumanIncidental findingIntrathoracic bifurcation of the left common carotid arteryKlippel Feil syndromePediatric patientPhysical examinationPneumoniaPriority journalRecurrent diseaseRib fusionRib malformationSchool childThorax radiographyCervical vertebraCommon carotid arteryDiagnostic imagingKlippel Feil syndromeRibX-ray computed tomography
