胰腺结核的影像学诊断(附4例报告)

Imaging Diagnosis of Pancreatic Tuberculosis: Report of 4 Cases

目的：本文对胰腺结核的影像学表现进行分析。材料与方法：４例胰腺结核均经手术病理证实，影像学检查方法包括：超声、ＣＴ和ＥＲＣＰ。结果：超声检查发现胰腺病灶呈低回声或无回声，可有周围淋巴结肿大；ＣＴ检查发现胰腺病灶及周围肿大的淋巴结呈低密度，此变化在增强扫描时更明显；ＥＲＣＰ胰管可有受压移位，但无破坏。结论：超声和ＣＴ检查可发现液化、坏死的胰腺病灶及受累淋巴结；ＥＲＣＰ可准确判断胰管情况。超声。

Objective: To analyse the image findings of pancreatic tuberculosis.Materials and Methods: All of the four cases were surgico pathologically confirmed pancreatic tuberculosis. Imaging modalities include ultrasonography, CT and ERCP. Results: Ultrasonographically pancreatic foci appeared hypoechoic or anechoic and surrounding lymph nodes might be enlarged. On CT scans both pancreatic foci and affected lymph nodes were typically low densitified which were more distinct on enhanced scans. On ERCT examination, pancreatic duct displacement could be discerned and its internal structure remained intact.Conclusion: Ultrasonography and CT can detect liquefied pancreatic mass and related lymph nodes clearly. ERCP can demonstrate pancreatic duct structures satisfactorily, Ultrasonography, CT and ERCP are reliable modalities in diagnosing pancreatic tuberculosis.
