Animals can also present collapsed following the rupture of the mass, leading to a haemoabdomen or occasionally can be found dead.  

Animals may have history of repeated episodes of collapse following 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 is involved animals may present in [[:Category:heart Failure|heart failure]]. If there is muscular involvement this often presents as a hard swollen mass.

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.
