Image SIS package End point of gut stasis
This picture shows the abdominal organs of a fat rabbit that died from gut stasis. He was presented for veterinary treatment because he was lethargic and anorexic. He died shortly after admission and the post-mortem examination was performed within an hour. A spur on an upper cheek tooth was discovered during post-mortem examination. It was digging into the cheek causing an ulcerated, necrotic area in the mucosa. This was the most likely cause of the anorexia and the triggering factor for gut stasis. The image shows several features of gut stasis. There is a pale fatty liver, some gastric ulceration, an empty caecum distended with gas and empty gas filled intestines. It takes at least 3 days for a rabbit to die from gut stasis. Death can be prevented by providing food and fluid (syringe feeding) and medication to stimulate gut motility. Treatment of the cause of gut stasis (in this case dentistry) is also necessary.

Image Blood in the abdominal cavity
Blood or blood-stained fluid in the abdomen is one of the macroscopic signs of RHD although it is not diagnostic. Differential diagnoses include trauma, ruptured tumours, and end-stage hepatic lipidosis where the liver is so friable that it splits and bleeds. This case was confirmed as RHD.

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 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.

Image 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.

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 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.

Image JPEG image RHD: macroscopic findings
Macroscopic abnormalities are not always obvious in rabbits that have died from RHD. Histopathology reveals severe underlying pathology in the liver, often accompanied by other organs. RHD was confirmed in this rabbit.

Image C header 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.
