This is a retrospective study that describes the historical, physical exam, radiographic, fistulographic, ultrasonographic, and surgical findings associated with non-gastrointestinal and extrathoracic foreign bodies in six dogs.
All dogs had a chronic draining tract or abscess.
Although radiographs were obtained in five of the six dogs, no foreign bodies were identified with this modality.
Fistulography was performed in four of the six dogs, and a filling defect consistent with a foreign body was found in two of four dogs.
A foreign body was identified in five of the six dogs with ultrasound.
Foreign bodies were removed surgically in five of six dogs. This report clarifies the importance of ultrasound in the evaluation of chronic draining tracts and abscesses in dogs.
