探讨胰腺结核多层螺旋CT（MSCT）表现，以提高胰腺结核诊断的正确性。

回顾性收集7例行MSCT检查并经病理确诊及随访证实的胰腺结核患者，分析胰腺结核的MSCT表现，分析其部位、边缘、密度、增强特征及与周边血管的关系。

7例胰腺结核中位于胰头者5例，胰腺颈部者2例；2例患者为类圆形，2例患者为圆形，3例患者呈不规则形，表现为略低密度肿块或囊性病变，边界不清，增强扫描呈蜂房状强化灶、环状或不均匀性强化。5例患者中伴胰头周围淋巴结肿大者3例，伴肝内外胆管及胰管轻度扩张者2例，胆囊增大者1例；2例患者显示肝动脉被病变及肿大的淋巴结侵犯、包绕。

MSCT检查不但可以明确胰腺结核病灶范围，而且MSCT表现有一定特征性，能进一步提高胰腺结核诊断的正确性。

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.
