Arteria lusoria, or the aberrant right subclavian artery, represents the most frequent congenital malformation of the aortic arch, although its prevalence remains under 2% of the population. While often asymptomatic, this anomaly can cause esophageal or tracheal compression, leading to clinical manifestations such as dysphagia and recurrent respiratory infections. We report the case of an 11-month-old infant presenting with solid-food selective dysphagia, recurrent wheezing, and fever. Radiographic and contrast-enhanced thoracic CT imaging confirmed the presence of a retroesophageal right subclavian artery, consistent with arteria lusoria. Initial management involved antibiotics for respiratory infection, dietary adaptations, and supportive measures, with referral for surgical evaluation. This case highlights the diagnostic importance of advanced imaging modalities in detecting vascular anomalies and emphasizes the need for early recognition of arteria lusoria in symptomatic pediatric patients to avoid complications and ensure timely treatment.
