Hepatic lipidosis- ruptured liver
-
Abdominal haemorrhage was found in this rabbit that died on the way home after examination and treatment for anorexia. During the consultation. the rabbit struggled as the owner was returning it to its carrier. Unfortunately the rabbit escaped and fell from the consulting table. Post-mortem examination showed that abdominal haemorrhage from a ruptured liver was the cause of death. The liver was pale (arrow). Histopathology confirmed the presence of heaptic lipidosis.

Haemorrhage in the mouth
-
Occasionally a spur on the tooth can perforate a major blood vessels in the mouth and cause fatal haemorrhage. In this case the buccal artery had been perforated by a sharp spur on the tooth that had torn the mucosa (arrow). A large blood clot was occluding the pharynx.

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.

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.
