This structure is the appendix as it connects (red arrows) to the end of the caecum that is gas-filled (green stars).
Radiographic description: There is a large tubular structure in the right caudal abdomen (1.7cm in diameter, 6cm long, orange stars), mostly fluid-filled with a small amount of collecting gas. This structure also contains cranially a denser structure (9mm by 2.5cm long, blue stars) that is partially aerated like the ingesta/faeces, but also has a mineral peripheral rim.
This rabbit went to surgery and the appendix was removed. It was infected and pus-filled. With hospitalization and supportive care this rabbit survived. Appendicitis is believed to be an under-reported cause of ileus/colic in rabbits. Diagnosis is difficult and best made with abdominal CT using contrast enhancement.
