==Description==

A highly malignant tumour of vascular endothelial origin. Commonly affect dogs and the most frequently affected areas are the spleen, pericardium, right atrium, liver and muscle.  The cat is affected less frequently and the most common sites are the liver, spleen and mesentry. Metastasis occurs via the haematogenous route or via rupture and transabdominal spread.  Metastatic sites include, lungs, liver, omentum, diaphragm and less commonly brain. Surgery is the treatment of choice but even with this survival time remains very short.

Animals may have history of multiple episodes of collapse following repeated rupture of an abdominal mass, leading to non-fatal haemoabdomen. Occasionally can be found dead following catastrophic rupture and fatal haemoabdmen.

In instances where the heart (right auricle) is involved, animals may die suddenly or present in [[:Category:heart Failure|heart failure]]. Rupture of the mass and haemorrhage into the pericardial sac leads to compression of the heart, which can no longer fill with blood during diastole (cardiac tamponade).

If the nervous system is involved a range of neurological abnormalities will also be present.
