Bridge bronchus and pulmonary artery sling: Case report and literature review.

ABSTRACT

We present the case of a 14-year-old adolescent boy with a history of poorly controlled asthma and a final diagnosis of a bridge bronchus associated with sling of the left pulmonary artery. Regarding the case report, we describe the characteristic findings in computerized tomography multidetector of the thorax, its classification, and the most relevant information about this malformation. Congenital malformations of the tracheobronchial tree may occur in the context of asymptomatic or symptomatic respiratory patients. These malformations may be associated with other vascular, tracheal, and syndromes with multiorgan involvement. Although most patients are asymptomatic, some of them will have nonspecific symptoms without a clear etiology or will be diagnosed incidentally during the diagnostic evaluation of other pathologies. It is important to know and recognize the normal anatomy and its variations, since radiology undoubtedly plays a fundamental role in the diagnosis and preoperative assessment of these malformations, which although they have low incidence, must be identified in a timely manner by the specialist in diagnostic images.
