Discussion on Pancreatic Calculus from Aspects of Roentgenology

The diagnosis of disseminated parapancreatic calculus is relatively easy from its specific roentgenogram, but in those cases with little roentgenographic shadow or with a solitary shadow it becomes quite difficult. Hence in the latter cases it is necessary to distinguish it from bilestone, kidney stone, peritoneal calcified lymph node, splenic venous thrombus, or duodenal diverticulosis. Therefore, for the diagnosis of the parapancreatic calculus it is important to take a single roentgenogram of the entire abdomen as well as lateral views of the abdomen, the combination of which would afford us to identify the parapancreatic calculus from the density of its shadow, its site and its size. We have recently encountered three patients with pancreatic calculus and present our observations of the cases as well as some remarks on them from the aspects of roentgenology.
