Congenital airway malformations can present with respiratory distress, cyanosis, and difficulty feeding in the neonate or infant. Clinical presentation may vary from asymptomatic to fatal airway obstruction. They may exist in isolation or in association with vascular rings and slings, bronchopulmonary malformations, and/or syndromes. We present an unusual case of bridging bronchus, complete bronchial rings, and left pulmonary artery sling presenting with recurrent croup, highlighting the importance of bronchoscopy and CT imaging to achieve an accurate diagnosis in patients with recurrent croup and/or respiratory failure not responding to usual treatment measures and a multidisciplinary treatment approach.
