IMAGING DIAGNOSIS—ACUTE MESENTERIC ISCHEMIA ASSOCIATED WITH HYPERTROPHIC CARDIOMYOPATHY IN A CAT

A middle‐aged cat was presented with vomiting, diarrhea, and pelvic limb paresis. Radiography showed cardiomegaly, interstitial pulmonary infiltration, distended intestinal loops, and portal venous gas. Hypertrophic cardiomyopathy (HCM) was confirmed. On CT, thrombi were identified at the abdominal aorta, superior mesenteric artery, bilateral renal arteries, and cauda vena cava at the level of the iliac vein bifurcation. Dilated and gas‐filled loops of bowel with a “paper thin wall” were observed on CT images and were considered indicative of necrotic bowel. This case report describes the CT findings of acute mesenteric ischemia associated with HCM in a cat.
