Plain-English summary
A 9-year-old Bouvier des Flandres was brought to the vet because he was coughing, seemed tired, and had fluid in his chest. An ultrasound of his heart showed a mass that was blocking blood flow from the heart. The vet performed surgery to remove the mass, which turned out to be an ectopic thyroid carcinoma (a type of cancer). Unfortunately, the dog was euthanized 11 months later due to ongoing issues with fluid in his chest that did not improve.

Abstract
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.
