Steeple sign
![](../I/m/Croup_steeple_sign.jpg)
The steeple sign as seen on an
anteroposterior neck X-ray of a child with croup.
In radiology, the steeple sign is a radiologic sign found on a frontal neck radiograph where subglottic tracheal narrowing produces the shape of a church steeple within the trachea itself.[1][2] The presence of the steeple sign supports a diagnosis of croup, usually caused by paramyxoviruses.[3]

Radiologic confirmation of proximal narrowing of the subglottic space can be • obtained by an AP radiograph of the neck; typically, a “steeple sign” is noted referring to the similar appearance of a church steeple.

This type of narrowing is typically present in croup and is known as the steeple sign on the anteroposterior radiograph given its similarity to a church steeple.
