Abstract
Purpose
The purpose was to evaluate characteristics of pancreatic cancer without main pancreatic
duct (MPD) dilatation on dual-phase computed tomographic (CT) scans.
Materials and methods
We studied 16 patients with pancreatic head cancer without accompanying MPD dilatation
and 39 patients with MPD dilatation
Results
Elevation of serum amylase level and peripancreatic fluid collection were more frequently
seen in the MPD(−). Common bile duct dilatation and atrophy of the upstream pancreatic
parenchyma were more frequently seen in MPD(+).
Conclusion
Pancreatic cancers without MPD dilatation were more frequently related to acute pancreatitis
and had fewer secondary signs. Thus, early diagnosis of pancreatic cancer with these
characteristics could be difficult.
