Overview
Key Chest X Ray Findings in Croup
- Steeple sign is seen on anteroposterior radiographs of the soft tissues of the neck.[1]
- Normal lateral convexities of the subglottic trachea are lost, and narrowing of the subglottic lumen produces an inverted V configuration in this area.
- The 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.Salour M (2000). "The steeple sign". Radiology. 216 (2): 428–9. PMID 10924564.</ref>
- Distension of the hypopharynx can is also be revealed by chest x ray, indicating a patient's attempt at decreasing airway resistance
