Image JPEG image RHD
This picture shows the abdominal contents of an adult lionhead neutered male rabbit that died the day after a general anaesthetic for dentistry. The liver is swollen and pale and there is haemorrhagic fluid in the abdomen. Histopathology showed characteristic signs of RHD, including hepatocellular necrosis. PCR testing confirmed the presence of RHDV2.

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 JPEG image Subtle macroscopic signs of RHD
Gross post-mortem signs are not always obvious in rabbits that died from RHD and this rabbit is an example. The liver is slightly enlarged and close inspection with a hand lens did show a mottled appearance. Histopathology showed characteristic hepatocellular necrosis and PCR testing confirmed the presence of RHDV2.
