Abstract
A 4-year-old intact female, mixed breed dog was presented with a complaint of dyspnea. Clinical examination revealed symptoms related to disease of the upper airways. Radiographic findings were consistent with tracheal collapse associated with anomalies involving the seventh cervical vertebra and the first ribs bilaterally. Radiographs were highly suggestive of cervical ribs; computed tomography and ultrasound examination allowed complete characterization and better localization of the anomalies with relationship to the adjacent muscle and vasculature. Cervical ribs are malformations widely described in human medicine, but only sporadically in dogs. Herein, we discuss etiological, clinical, diagnostic and therapeutic aspects of cervical ribs and possible correlations between the cervical ribs and other anatomical anomalies noted in this dog.
