A case of a four-year-old spayed female Maltese presented with an acute cough. In a variety of examinations, traumatic diaphragmatic hernia was suspected, and surgery was performed. During surgery, visual inspection of the diaphragm confirmed intact with normal-sized vena caval foramen and a herniation of the entire right medial liver robe through the vena caval foramen into the right thoracic cavity. The diagnosis was a caval foramen hernia. Contrast-enhanced computed tomography (CT) revealed a herniation of the entire right medial liver lobe with normal branches of hepatic veins and portal veins, and surgical repair of the hernia was attempted. After successful surgical repair, the biopsied specimen from the right medial liver lobe was revealed to be histologically normal. Contrast-enhanced CT is considered as a useful diagnostic modality for determining treatment in dogs.
