title: Reversible acquired tracheobronchomalacia of a combined crescent type and saber-sheath type.
abstract: A case of tracheobronchomalacia (TBM) in a 71-year-old woman, who had suffered a cough syncope, is reported. It was a combination of both the crescent type (the posterior membranous portion of trachea or bronchus protrudes into the lumen) and the saber-sheath type (the lateral cartilaginous wall of trachea or bronchus protrudes into the lumen). In this patient, acute bronchitis had developed superimposed upon a chronic bronchitis in addition to age-related regressive changes of the trachea and bronchus. A TBM due to acute inflammation can be reversible, but aggressive airway management as well as medical treatment of the underlying inflammation are critical to a successful outcome.
