True Tracheal Bronchus:

[摘要] Aberrations in tracheobronchial branching patterns are occasionally encountered during tracheobronchosopy. In this case, a 19-year-old man with chronic respiratory insufficiency and subsequent tracheotomy at an outside hospital was sent for evaluation of his tracheotomy, with exam findings as shown in Figure 1. Approval was obtained from The Johns Hopkins Hospital Institutional Review Board for submission of this report.
