Triple-phase helical computed tomography of an arterio-hepatic venous shuntin a hepatic tumor in a dog

[摘要] A 10-year-old French bulldog presented with an abdominal tumor. Triple-phase helicalcomputed tomography was performed, revealing a hepatic tumor, an enlarged hepatic lymphnode, and no masses in other organs. The hepatic tumor demonstrated marked enhancement,similar to that of the aorta in the arterial phase. The tumor had rich vascularization anda hepatic arterio-venous shunt formed between the hepatic artery and middle hepatic vein.The hepatic tumor was surgically removed and histological diagnosis revealed a hepaticcarcinoid tumor. During surgery, rapid massive arterial hemorrhage occurred from the siteof the incision. The animal died without improvement post-surgery. In the case of anarterio-venous shunt in a hepatic tumor, it is important to be careful to avoidperioperative bleeding.
