Test

Croup is largely a clinical diagnosis.Therefore, x-ray should not be performed in a child presenting with typical symptoms and signs of croup. The steeple sign (narrowed trachea) is a classic finding on anteroposterior view, but is not always present.

Radiological studies are contraindicated if there is clinical suspicion of epiglottitis or bacterial tracheitis, as manipulation of the neck region and agitation may precipitate further airway obstruction. If the clinical picture is atypical for these conditions, soft-tissue radiographs of the neck may provide helpful information to support an alternative diagnosis. Any x-ray should be performed with considerable care and personnel equipped to support the airway in the event of worsening obstruction.
