ABSTRACT

The bridge bronchus (BP) along with the pulmonary artery sling (SAP) are already described, but infrequent, congenital anomalies as a cause of persistent stridor in children. The case of a 3-year-old patient referred to as dyspnea, recurrent respiratory infections and suspected vascular ring is described. When examining she presented stridor evident so we decided to request bronchoscopy which does not show main bronchus right nor allows to pass to the left. The multislice computed tomography demonstrates the presence of a bridge bronchus associated with pulmonary sling. The presence of both malformations is classified as type 2B according to the contribution of wells and landing and although its diagnosis was mostly post-mortem in past times, the current technology allows to confirm it in a timely manner.

KEYWORDS
