Computed tomography of the dilated main pancreatic duct

The ducts of the pancreas undergo changes secondary to pancreatic disease. This report is based on computed tomographic studies of 13 cases with enlarged main pancreatic ducts. All patients showed severe pancreatic disease of tumoral or inflammatory etiology. The dilatation of the main pancreatic duct was confirmed by endoscopic retrograde cholangiography and pancreaticography, surgical intervention, biopsy, and/or autopsy in all but two cases.
