Recently, we experienced 3 cases of chronic pancreatitis and 4 cases of pancreatic cancer. The following are the results of the ultrasonic examination of these cases. = Chronic Pancreatitis : Some of the cases of chronic pancreatitis have atrophy and / or regional or whole swelling in the pancreas. Most of the internal echo images were spotted type, but the strong echoes and echo spots due to the presence of pancreatic calculi were noted in some of them. Therefore, it was difficult to discriminate the cases which showed mottled pattern echoes and those of the regional Tumor Forming type of chronic pancreatitis from the cases of pancreatic cancer. Pancreatic Cancer : The subjects of this study were two each of both sexes ranging between 50-70 years of age. There were 2 cases of pancreatic head tumor and 2 of pancreatic body. A regional hypoechoic mass and the dilatation of the caudal main pancreatic duct were seen in the pancreatic body. Ordinarily, parenchymal tissue of the pancreas is seen in the hypoechoic area. But hyperechoic or mottled pattern for the necrotic one and a cystic pattern for the region of colliquative necrosis is necrogenized. Since the symptoms of early pancreatic cancer are few, the rate of its diagnosis is only 200/0 or so at present. The treatment of the pancreatic cancer has been conducted mainly by multidisciplinary or surgical therapy. Generally, the prognosis is not good. It is said that the five-year survival rate is between less than 5％ to 10％.
