自身免疫性胰腺炎的内镜超声表现

目的 分析总结自身免疫性胰腺炎在内镜超声的特征表现.方法 回顾分析2004年8月至2007年9月确诊的11例原发性自身免疫性胰腺炎的临床资料,总结内镜超声的影像特点.结果 内镜超声下见胰腺实质回声极低,胰腺弥漫或局部增大,边缘呈波浪样改变;肝外胆管扩张,胆管壁明显增厚,呈均匀中低回声;可见胰腺周边淋巴结肿大.所有病例均未见明显胰管扩张或胰石、胰腺钙化和囊肿形成;未见周边血管受累.结论 自身免疫性胰腺炎在内镜超声下具有相对特征性的表现,有助于自身免疫性胰腺炎的临床诊断.

Endoscopic ultrasonography in patients with autoimmune pancreatitis

Objective To analyze the characteristics of EUS imaging in the patients with autoimmune pancreatitis(AIP).Methods Eleven cases of AIP were studied retrospectively,and features of EUS were analyzed.Results EUS revealed diffuse or focal enlargement of pancreas along with hypoechoic parenchyma and a wavy margin.In addition to dilation,the bile duct had a prominently thickened wall with homogenous mild hypoechoic image.Peripancreatic lymph nodes could be enlarged.No pancreatic duct dilation.calcification or cysts were found.No peripheral vessels were involved.Conclusion EUS could demonstrate specific images which is helpful in diagnosis of AIP.
