A 9-year-old, intact female Shih-tzu dog presented with a three-week history of anorexia, lethargy, and weight loss. Abdominal radiography revealed a mass in the right cranial quadrant of the abdomen that was displacing the right kidney caudally. Ultrasonography showed a large, irregular, heterogeneous hepatic mass and a small amount of peritoneal fluid. On computed tomography (CT), a large hypoattenuating mass with heterogeneous contrast enhancement occupied the right lateral lobe, and parts of the right medial and caudate lobes of the liver. There was no evidence of regional lymph node or pulmonary metastasis. Lobectomy of the right medial, right lateral and caudate liver lobes was performed, however, the patient did not recover from surgery. Hepatoblastoma was confirmed by histological examination. Hepatoblastoma is rare in dogs, and this is the first report describing CT imaging of hepatoblastoma in a dog.

제안 방법
A CT examination was performed with a 32-multislice CT system (Alexion , Canon Medical Systems, Tokyo, Japan). The patient was positioned in sternal recumbency on the CT table without anesthesia.
대상 데이터
Although the diagnosis is confirmed by histopathological examination, diagnostic imaging, such as radi- ography, ultrasonography, and computed tomography (CT) is helpful for diagnosis. This study described the diagnostic imaging, including CT, of a rare case of hepatoblastoma in a dog.
A 9-year-old, intact female, Shih-tzu was presented with three weeks history of anorexia, lethargy, and weight loss from 4.10 to 3.45kg. On physical examination, the dog showed mild icterus, pale mucous membranes, and body condition score 3 of 9 point scale.
However, it has not previously been reported in young dogs. In this study, the dog was nine years old at the time of diag- nosis. The differences in the age at incidence between humans and dogs may be related to the causes of hepatoblastoma, which are mostly obscure in humans (13).
후속연구
The causes of hepatoblastoma in dogs are unknown; however underlying hepatic disease may play a more influential role than do hereditary factors in old dogs, as with hepatoblastoma in adult humans. Hepatoblastoma in neonatal or young dogs has not been studied previously, therefore, further studies are needed.
The reason may be the patient’s age and the cause of hepatoblastoma develop- ment. Because this study is the only report on CT findings of hepatoblastoma in a dog, comparative studies of additional CT findings in dogs with hepatoblastoma are needed.
