Parotid duct foreign body in a dog diagnosed with CT.

A 12 mo old castrated male German shorthaired pointer was referred with a 3 mo history of a recurrent left-sided facial swelling. Contrast-enhanced computed tomography (CT) combined with a positive contrast sialogram revealed the presence of a thick-walled dilated region of the left parotid duct and a normal appearance of the parotid gland. The affected parotid duct, complete with grass seed foreign body, was surgically removed under general anesthesia, and the parotid duct was ligated leaving the parotid gland in situ. Twelve mo later, the dog was doing well with no reported complications.
