Chest X Ray
- Steeple sign is seen on anteroposterior radiographs of the soft tissues of the neck.
- Normal lateral convexities of the subglottic trachea are lost, and narrowing of the subglottic lumen produces an inverted V configuration in this area.
- Point of the inverted V is at the level of the inferior margin of the true vocal cords.
- Narrowing of the subglottic lumen alters the radiographic appearance of the tracheal air column, which resembles a steeply pitched roof or a church steeple.
- The lateral radiograph of the upper airway will show a normal epiglottis and narrowing of the subglottic region.
