Steeple sign (trachea)

Last revised by Mostafa Elfeky on 26 Oct 2023

The steeple sign (also called the wine bottle sign, and inverted V sign), refers to the tapering of the upper trachea on a frontal chest radiograph reminiscent of a church steeple, suggestive of croup. A corresponding lateral x-ray would show narrowing of the subglottic trachea and ballooning of the hypopharynx.
