Image Buzzard attack
This juvenile wild rabbit was found after a Common Buzzard was disturbed and flew into a tree that was close by. The body was warm and limp indicating that the rabbit had only just died. There were no visible marks or wounds on the body. After the skin was partially removed, four small tears were found that penetrated either the thorax or abdomen. One of these had caused substantial haemorrhage. These marks were consistent with wounds inflicted by talons. There was more severe damage internally.

Image Spleen in a rabbit with RHD2
The spleen must be found during a post-mortem examination. Lifting the stomach and reflecting it dorsolaterally the spleen can be found, attached to the stomach by the lesser omentum. In this case it is at least double the size it should be. This is a sign of RHD.

Image Splenomegaly
An enlarged spleen may be seen in cases of RHD. There are few other causes of splenomegaly in this species. Histologically the changes can range from moderate congestion to haemorrhage, deposition of fibrin, lymphocytolysis and necrosis of lymphoid tissue.

Image Enlarged pale, mottled liver
The liver is always affected in rabbits with RHD. Microscopically hepatocellular necrosis is present in all cases. Macroscopically, there may be minimal changes or hepatomegaly with a pale mottled appearance as in this rabbit that died from RHDV2 confirmed by PCR testing.

Image JPEG image Enlarged, congested, mottled liver
Congestion is often present in the organs of rabbits that have died from RHD and can mask other characteristic changes. The liver of this rabbit that died from RHD is congested. Close inspection shows a mottled appearance.

Image Enlarged congested liver
An enlarged congested liver can be due to rabbit haemorrhagic disease (RHD) but is also a macroscopic feature of other conditions, such as congestive heart failure or septicaemia. Close inspection of the liver shows a mottled appearance, which is suggestive of RHD. In this case, RHD was diagnosed from the histopathological finding of characteristic hepatocellular necrosis.

Image Octet Stream Pulmonary congestion and oedema
Pulmonary haemorrhage and oedema are features of RHD although, macroscopically, it can be difficult to differentiate agonal changes, such as alveolar collapse, congestion, and alveolar oedema from lung pathology. In this confirmed case of RHD, fibrin thrombi were seen in occasional small capillaries and venules on histopathological examination.

Image ECMAScript program Ecchymotic pulmonary haemorrhages
In this confirmed case of RHD, ecchymotic haemorrhages were evident macroscopically and alveolar haemorrhages were seen microscopically.
