Spontaneous Bowel Infarction in a Golden Retriever
History: This 7-year-old MN Golden Retriever presented for anorexia of sudden onset. The physical exam revealed fever of unknown origin, tacky mucosal membranes, and focal splinting abdominal pain cranial to the urinary bladder. The CBC revealed mild/moderate neutrophilic leukocytosis (23,000 wbc/hpf). Chemistry panel and urinalysis were uneventful.
The abdominal sonogram revealed a focal painful region of distal small intestinal pathology with ill-defined hyperechoic adhesion pattern of surrounding mesentery that is attached and associated with the compromised intestine cranial to the urinary bladder. There is a complete loss of intestinal mural detail in the affected small intestine with gas penetration into the wall. The patient was extremely painful on imaging this structure. Primary differentials included perforating intestine due to underlying neoplasia (LSA, MCT, carcinoma), transmural inflammatory disease, bowel infarction, foreign body passage.
