2y FS Bernese Mountain Dog with stridor. There is a sessile soft‐tissue mass that arises from the ventral tracheal wall and appears to be
primarily intraluminal (a: arrow). The mass proves to be of mixed soft‐tissue and mineral opacity on unenhanced CT images (b,c) and
mildly enhances following contrast administration (d). CT imaging confirms the mass is well defined and is restricted to the ventral tra­
cheal wall. Bronchoscopic evaluation supports the radiographic and CT imaging findings (e). Biopsy confirmed the mass to be an
osteochondroma.
