Our patient had a displaced type II right-sided tracheal bronchus, with multiple associated pulmonary, hepatic and renal vascular anomalies.
A higher occurrence of tracheal bronchus has been found in patients with congenital heart diseases, with other vascular abnormalities also described.
conclude that the presence of a clinically significant tracheal bronchus should be considered in every child with recurrent right upper lobe pneumonia, especially in those with Down's syndrome or rib abnormalities.
The bronchoscopy revealed a tracheal bronchus. (figure 1).
Because tracheal bronchus, while uncommon and usually asymptomatic, may be associated with significant morbidity and possibly mortality, clinicians should keep this anomaly in mind when evaluating a patient with recurrent symptoms localized to the right upper lobe region.
Tracheal bronchus and lung cancer association is rarely stated in the literature.
Tracheal bronchus is accepted as a normal anatomical variation in some animals like sheep, pig, camel, goat and giraffe while it is seen as a congenital anomaly in human beings.
