Pancreatic ductal adenocarcinoma of the uncinate process of the pancreas: histology with triple-phase helical CT correlation in mild chronic pancreatitis of the pancreas upstream. Extensive mild fibrosis in the upstream pancreatic tissue (HδE 100×) (a) and pancreatic ductal adenocarcinoma with severe fibrous stromal reaction (HδE 100×) (b). CT shows maximum enhancement on portal venous phase for upstream pancreatic tissue (c-e) and increasing pattern for pancreatic ductal adenocarcinoma (f-h). Note dilatation of main pancreatic duct in the pancreas upstream to the tumor.
