Abstract

|
A ten-year-old Yorkshire Terrier developed serious abdominal distension and respiratory distress. Radiography and ultrasonography revealed a hyperechoic mass around the aorta that was contiguous with the right atrium and main pulmonary artery. It was resulted in failure of the right side of the heart including tricuspid regurgitation, hepatomegaly with dilation of the hepatic vein and severe ascites due to a large, expansile mass. Computed tomography(CT) identified a large mass originating at the cardiac hilar region and spanning from the cranial vena cava to the caudal vena cava. The tumor had invaded the cranial vena cava, caudal vena cava, heart and pleural wall. A tentative diagnosis of chemodectoma was assigned to the tumor through a fine needle aspiration. This report focuses on the typical features of imaging diagnosis of heartbase tumors by radiography, ultrasonography and CT.
