Liver lobe torsion
-
This image shows the liver of a rabbit that had died from a liver lobe torsion. The caudal lobe has twisted around so the blood supply was cut off. The rest of the liver has fatty infiltration.

Liver lobe torson
-
This image shows the liver of a rabbit that died from a torsion of the caudate process of the caudal lobe of the liver (arrow). This is the most common part of the liver to be involved in liver lobe torsion in rabbits. The image shows its position behind the ribs on the right side of the abdomen

Metastasised uterine tumour
-
This is a post-mortem image of the abdominal contents of an aggressive uterine tumour. The tumour was confirmed in the living rabbit by exploratory laparotomy. The uterus is in the lower part of the picture. The larger mass of metastasised (spread) tumour is in the upper half. There were other small tumours throughout the peritoneal cavity. The rabbit was euthanased during surgery which is why the body can be seen through the semi-transparent surgical drape.

Myocardial haemorrhages
-
Disseminated intravascular coagulopathy is a feature of acute cases of RHD and haemorrhages may be found in any part of the body. In this case, there were multifocal areas of haemorrhage in the myocardium, which were evident macroscopically and microscopically.

PATHOLOGY
-
Predator attack
-
This image shows the internal organs of a rabbit that was found dead. There is free blood in the abdomen. Although a diagnosis of RHD might be made, closer examination shows that the gross appearance of the liver is normal, and the haemorrhage originated from a puncture wound across the chest wall. The rabbit died from predator attack.

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.

Rabbit Haemorrhagic Disease
-
This half-grown female wild rabbit was found dead. There were no signs of external injury. Post-mortem examination revealed a full gastrointestinal tract - the rabbit had been eating up until an hour or two before death. The liver was enlarged and mottled, the lungs contained several haemorrhages in addition to a pale, necrotic area in the left caudal lung lobe. Histopathology showed the characteristic hepatocellular necrosis of RHD. The pale area in the lung was an aspergilloma and there was also evidence of hepatic coccidiosis. The case was confirmed as RHDV2 with PCR testing.

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.
