Tracheal bronchus, also referred to as bronchus suis or pig’s bronchus, is a rare tracheobronchial anomaly in which an ectopic bronchus arises from
the lateral wall of the trachea above the carina and supplies the entire upper lobe or a segment of the upper lobe. It affects 0.5 - 2% of the population
and may be detected incidentally, or in patients who present with bronchospasm, persistent cough, recurrent upper lobe infections and haemoptysis.
Surgical resection is reserved for patients with severe or persistent symptoms that are resistant to treatment. We present a case of a symptomatic
5-month-old baby who had a type II right-sided tracheal bronchus on bronchography and CT.
