Cylindromas usually arise from the middle third of trachea presenting as an endotracheal mass with extratracheal extension. The propensity to invade locally results in frequent recurrence of the tumor after removal. They can, therefore, masquerade as asthma for some period of time before being discovered. A more penetrated film may show the endobronchial tumor. CT usually shows a smooth hemispherical density in the air column of the trachea accompanied by an extratracheal soft tissue mass.
