Chemodectomas appear as soft nodular encapsulated homogeneous masses mainly growing at the base of the heart. Diagnosis and Treatment. The primary differential for a mass located at the heart base in a dog is chemodectoma also known as aortic body tumor or paraganglionoma a slow-growing neuroendocrine tumor that is most common in brachycephalic breeds.
