U. Braun et al., ECHOCARDIOGRAPHIC DIAGNOSIS OF A CARDIAC FIBROSARCOMA IN THE RIGHT ATRIUM OF A SHEEP, Schweizer Archiv fur Tierheilkunde, 137(5), 1995, pp. 187-192
This is a case report of a six-year-old female White Alpine sheep with
a cardiac fibrosarcoma in the right atrium. Clinically, the sheep had
right-sided cardiac insufficiency with tachycardia, engorgement of th
e jugular veins, brisket edema, and ascites. Chronic congestion of the
liver resulted in increased hepatic enzyme activity. Based on clinica
l findings, a tentative diagnosis of endocarditis or pericarditis was
made. Radiography of the thorax revealed hydrothorax. An echogenic mas
s was observed in the right atrium via echocardiography; it was interp
reted as a tumor or thrombus. Ultrasonography of the abdomen revealed
severe ascites and chronic congestion of the liver attributable to rig
ht-sided cardiac insufficiency. The clinical and sonographic findings
were verified at post mortem. The mass in the right atrium was a pedun
culated fibrosarcoma.
