Abstract
Case 1: A female in her 60s was found to have a pancreatic solid lesion by transabdominal ultrasonography (US) during a health check-up in our hospital. Endoscopic ultrasonography (EUS) identified a hypoechoic mass with repeatability of US, but contrast-enhanced computed tomography (CE-CT) did not detect the lesion on detailed examination. Based on the diagnosis of pancreatic body cancer, we conducted distal pancreatectomy with splenectomy. We diagnosed it as a 1cm intraductal papillary mucinous carcinoma of the pancreas.
Case 2: A female in her 70s was found to have dilatation of the main pancreatic duct (MPD) by US during a health check-up in our hospital. CE-CT showed no mass in the pancreas. EUS detected a hypoechoic mass in the pancreatic head and the distal MPD from the lesion was dilatation. Based on diagnosis of pancreatic head cancer, we performed pancreatoduodenectomy and histological diagnosis was 1.5cm pancreatic invasive ductal cancer. EUS was useful in detailed examination of the pancreas, because the pancreatic lesions indicating abnormal findings on the health check-up might be a small pancreatic cancer.
