Abstract
Tracheal Bronchus: Rare Cause of Recurrent Pneumonia and Worsening Bronchiectasis in Adults
Highlights
True tracheal bronchus is an aberrant bronchus arising above 2-6 cm from carina, from the lateral wall of trachea and directed towards the upper lung lobe [1]
The incidence of 0.31% was reported via multidetector computed tomography (MDCT) analysis in a study of 9k cases
We described a rare presentation of tracheal bronchus in late adulthood in the form of recurrent respiratory infections
Summary
True tracheal bronchus is an aberrant bronchus arising above 2-6 cm from carina, from the lateral wall of trachea and directed towards the upper lung lobe [1]. Located on the right side, it can be further described as supernumerary if there is an anatomic right bronchus with normal segmental apical, anterior and posterior bronchi. It is considered displaced if it’s accompanied by an absence of anatomic segmental bronchi. Incidence described in the literature ranges from 0.1 to 1% reported in different studies. The incidence of 0.31% was reported via multidetector computed tomography (MDCT) analysis in a study of 9k cases. We described a rare presentation of tracheal bronchus in late adulthood in the form of recurrent respiratory infections
