Today’s case is in the non-domestic animal category. It’s an 8-year-old male neutered rabbit with lethargy. See what you think and post your findings in the comments section.
The colon, cecum, and small bowel are mostly empty. The margins of the liver, bladder, and cecum are well defined. There is radiodense debris within the urinary bladder. There is a fat opacity mass in the mid-abdomen, which is causing a mass effect, displacing the cecum and small bowel cranially and ventrally.
The mass effect helps to identify a mass of lesser opacity than soft tissue. It is slightly more opaque than fat normally seen in the abdomen because of its large size. The mass may have caused ileus because of compression of the bowel.
The sediment in the urinary bladder contains calcium and is a common finding in rabbits.
