Abstract
A 76-year-old man was admitted because of a large cystic lesion detected by ultrasonography. Contrast computed tomography demonstrated a low cystic lesion with a nodular enhanced mass in the body of the pancreas and an enhanced mass in the right lobe of the liver. Endoscopic retrograde pancreatography showed an obstruction of the main pancreatic duct in the body of the pancreas. MRI detected the cystic lesion as a hyperintense mass on T2-weighted imaging. Angiography demonstrated the tumor in the body of the pancreas and in the liver. Distal pancreatectomy and splenectomy were performed. Histological examination revealed invasive intraductal tubular carcinoma with a large bloody cystic lesion, and the sequence of intraductal tubular adenoma to carcinoma.
