Truncus Bicarotidus and Arteria Lusoria: A Rare Birth Defect

We present the case of a 50-year-old woman who underwent a CT scan of the chest as part of a surveillance examination during which a congenital anomaly of the branches of the aortic arch was discovered. It was a bicarotid trunk associated with an aberrant right subclavian artery, with no other abnormal vascular arrangement. This rare type of anomaly is usually discovered in childhood or when symptoms appear. Our patient had no knowledge of an episode of dyspnea-type respiratory disorder or dysphagia-type digestive disorder. This anomaly had never been reported to him. Educating clinicians about this anomaly is important for cardiologists and interventional radiologists given the growing number of cases.
