Simultaneous occurrence of anomalous cardiac and tracheal bronchi: a case study

A rare case of a combination of an accessory cardiac bronchus and a right tracheal bronchus found incidentally is presented, together with a discussion of the anatomy, embryology, and possible clinical ramifications of these anomalies. The incidence of these anomalies occurring in 2,000 tomographic studies of the chest at University of South Alabama Medical Center is cited.
