To investigate the imaging features of pancreatic tuberculosis in multislice spiral CT (MSCT), and to improve the accuracy of the diagnosis.

The clinical data of 7 cases of pancreatic tuberculosis proved by MSCT and diagnostic therapy were analyzed, retrospectively. All cases were confirmed by pathology or follow-up. The image characteristics of pancreatic tuberculosis included its location, boundary, density, enhancement features, the relationship between the lesion and peripheral vessels.

There were 5 cases with tuberculosis in the head of pancreas, 2 cases with tuberculosis in the neck of pancreatic in the study. The lesion form were 2 cases of round, 2 cases of circular, and 3 cases of irregular shape. Pancreatic tuberculosis often showed low density mass or cystic lesion, and their boundary was not clear, with honeycomb enhancement, rim enhancement or nonuniformity reinforcement after contrast injection. There were 3 cases with lymph nodes surrounding the pancreatic head, 2 cases with bile duct mild expansion of liver inside and outside, and the pancreatic duct, and 1 case with gallbladder enlargement in 5 cases with pancreatic tuberculosis. Two cases showed hepatic artery was invaded and enveloped by intumescent lymph nodes.

MSCT examination could not only clearly show the lesion range of pancreatic tuberculosis, but also could reveal a certain characteristic features. It can improve the accuracy of the diagnosis of the pancreatic tuberculosis.
