Steeple sign (trachea)

The steeple sign, also called the wine bottle sign, refers to the tapering of the upper trachea on a frontal chest radiograph reminiscent of a church steeple. The appearance is suggestive of croup, which should be obvious clinically. A corresponding lateral x-ray would show narrowing of the subglottic trachea and ballooning of the hypopharynx.
