Abstract Colonic torsion is a life‐threatening condition that results in colonic ischemia, necrosis, perforation, sepsis, and eventual death. The aim of this multicenter, retrospective case series study was to describe the CT findings dogs with surgically confirmed torsion. Medical records were searched for following abdominal CT. Five met inclusion criteria. Three had history chronic intermittent diarrhea prior presentation. Two presented acute vomiting, diarrhea, pain one dog vomiting lethargy. Computed tomographic all include: “whirl sign,” displacement distension cecum colon, focal narrowing mesenteric vasculature (5/5); streaky peritoneal fat effusion (4/5), pneumatosis coli (2/5), small intestinal portal vein thrombosis (1/5), reduced wall contrast enhancement (1/5). In (5/5), site descending colon demonstrated an anticlockwise rotation. At surgery, three five partial hyperemia at obstruction two complete marked necrosis wall. Displacement cecum, segmental presence sign” are highly suggestive
