Today’s case is a 6-year-old female neutered Dachshund with intermittent lethargy, coughing, and gagging. What are your findings?
There is an increased soft tissue opacity at the heart base causing rightward deviation of the trachea on the dorsoventral projection. The bronchus of the caudal subsegment of the left cranial lung lobe is displaced dorsally by soft tissue opacity. The heart and pulmonary vasculature appear normal. No abnormalities are noted in the pulmonary parenchyma.
Heart base mass causing displacement of the cranial lung lobe bronchus. The most likely diagnosis is chemodectoma. CT scanning is recommended for further characterization.
Presumed choroid plexus tumor. The dog underwent radiation therapy, and her clinical signs resolved.
