(d) GP

2y FS Australian Shepherd with hypoproteinemia and abdominal effusion. Survey radiographs show a globoid cardiac silhouette consistent
with pericardial effusion (a). Marked, eccentrically distributed pericardial effusion is present on CT images, and the contrast‐enhanced image
reveals irregular septations within the pericardial sac and an ill‐defined enhancing mass (c: white arrowhead) adjacent to the left ventricular
free wall (c: black arrowhead). Cytology of the pericardial fluid was described as hemorrhagic with mixed inflammation. A cystic, multilobular
mass was incompletely excised from the surface of the left ventricle (d) and determined to be a mesenchymal hamartoma.
