 AB    Echocardiography was valuable in identifying tumorous growth in the
       cardiac tissues of a bull with enzootic bovine leukosis. The tumor was
       discernable as a thickening of the interatrial septum and wall of the
       right atrium, accompanied by an immobile pedunculated mass that
       originated from the interatrial septum and extended into the lumen of
       the right atrium. The mass did not interfere with right atrioventricular
       valve function. The pedunculated mass and thick portion of the atrial
       wall had a similar echogenic appearance; both were hypoechoic, when
       compared with the wall of the right ventricle. A thin anechoic rim
       surrounding the heart was indicative of mild pericardial effusion.
       Echocardiographically detectable abnormalities in combination with
       results of other clinical examinations were the basis for recommending
       euthanasia of the bull.
