A 9-year-old Bouvier des Flandres was presented with coughing, lethargy, chylous pleural effusion, and a heart murmur. An echocardiogram revealed the presence of an intracardiac mass causing right ventricular outflow tract obstruction. The mass was successfully removed surgically, using total inflow occlusion. Histopathology and immunohistochemistry identified the tumor as an ectopic thyroid carcinoma. The dog was euthanized 11 months after diagnosis at the request of the owner because of nonresolving chylothorax.
