Tracheal Bronchus Presenting with Recurrent Haemoptysis in an Adult Female

Abnormal bronchus arising directly from the trachea or the main bronchus is a rare developmental anomaly of the tracheobronchial tree. In general, tracheal bronchus has been reported in less than 1% of adult patients undergoing bronchoscopy with a male predominance. Tracheal bronchus is classified as—‘displaced’ and ‘supernumerary’, the former being the most common type reported. Most patients are asymptomatic; however, cases presenting with cough, haemoptysis or recurrent lung infections are not uncommon. The diagnosis is usually made through computed tomography or bronchoscopy. Awareness of this anomaly may help in timely identification or prevention of perioperative complications during general anaesthesia or resectional thoracic surgery. Herein we report a case of right-sided displaced tracheal bronchus in an adult female presenting with recurrent haemoptysis.
