NEWELL-FUGATE, A  and  LANE, E. Periaortic haemangiosarcoma in an African wild dog (Lycaon pictus). J. S. Afr. Vet. Assoc. [online]. 2009, vol.80, n.2, pp.108-110. ISSN 2224-9435.

A 9-year-old apparently healthy male African wild dog (Lycaon pictus) was found dead in its enclosure at the De Wildt Cheetah and Wildlife Centre. Necropsy revealed a pericardium distended by approximately 250 ml of thick blood. A soft, red, lobulated mass was attached to the periaortic fat between the level of the aortic valves and the pericardial reflection. Histologically, the mass was consistent with a haemangiosarcoma. Other findings in the heart included mild to moderate ventricular hypertrophy and moderate, acute perivascular myocardial necrosis. Sudden death was attributed to acute heart failure precipitated by cardiac tamponade.

Keywords : African wild dog (Lycaon pictus); cardiac tamponade; heart failure; haemangio-sarcoma; pericardium; ventricular hypertrophy.
