CT Diagnosis of the Small Pancreatic Carcinoma

Objective To study the CT signs of the small pancreatic carcinoma. Methods The CT data of the 41 cases of the small pancreatic carcinomas proved by surgical pathology were retrospectively analyzed. Results Twenty nine of 41 cases were located in the heads or necks, 10 cases in the processus uncinatus, 2 cases in the bodies. The maximize size of 41 small pancreatic carcinomas were ranged from l.0cm to 3.0 cm. Twenty six were presented as isodensity and l5 were low density on the unenhanced CT images. All of them showed low density with peripheral enhanced on the enhanced images. Most of them accompanied with dilation of intra or extra hepatic bile duct, pancreatic duct and deformed the contour of the pancreas. Conclusion The small pancreatic carcinomas were presented as low density on enhanced images, dual phase enhanced spiral CT was more valuable than dynamic enhanced CT.
