RESUMEN
BACKGROUND: This case report describes the clinical and ultrasonographic findings in a Swiss Braunvieh cow with lymphosarcoma of the abomasum. CASE PRESENTATION: The main clinical findings were vomiting in response to eating and melena. The results of serum biochemistry and rumen fluid analysis were indicative of abomasal reflux syndrome. The main ultrasonographic findings were two enlarged lymph nodes caudal to the reticulum and a severely enlarged abomasum with thickening of the abomasal wall and folds. Based on all the findings, pyloric stenosis caused by lymphosarcoma was tentatively diagnosed and later confirmed at postmortem examination. CONCLUSIONS: This is an interesting case, which broadens the spectrum of abomasal reflux syndrome.

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.
