自身免疫性胰腺炎患者胰腺外器官受累时的超声表现

Ultrasonographic findings of extrapancreatic lesions associated with autoimmune pancreatitis

目的:探讨自身免疫性胰腺炎(autoimmune pancreatitis,AIP)患者胰腺外器官受累时的超声表现.方法:回顾性分析16例AIP患者的胰外组织器官超声表现,包括胰管、胆管、胆囊、胰腺周围淋巴结、肾脏、腮腺、颌下腺及泪腺,对声像图特点进行分析.观察胰管及胆管有无扩张,胰腺周围是否存在肿大淋巴结,肾脏回声是否均匀,腮腺、颌下腺及泪腺是否存在类似干燥综合征样超声改变.结果:16例AIP患者均进行了胰管、胆管、胆囊、胰腺周围淋巴结、肾脏的检查,分别有6、8、6、3、0例出现了超声异常,10例进行了腮腺、颌下腺、泪腺检查,分别有1、3、7例出现了超声异常.结论:AIP患者泪腺改变的发生率高,有可能在AIP与胰腺癌的鉴别诊断中具有重要的意义.

AIM： To summarize ultrasononographic find- ings of extrapancreatic lesions associated with autoimmune pancreatitis （AIP）. METHODS： Sixteen patients with AIP underwent ultrasound examination of the pancreatic duct, bile duct, gall bladder, peripancreatic lymph nodes, kidneys, parotid glands, submandibular glands, and lacrimal glands to observe whether the pancreatic duct and bile duct were dilated, the gall bladder wall was thickened, parapan- creatic lymph nodes were enlarged, echoes of the kidneys were evenly distributed, and the parotid glands, submandibular glands and lacri- mal glands mimicked symptoms associated with Sjogren＇s syndrome RESULTS： Of 16 patients, 6 had dilated pancre- atic ducts, 8 had dilated bile ducts, 6 had thicken- ing of the gall bladder wall, and 3 had enlarged peripancreatic lymph nodes. Of 10 patients who underwent examination of the parotid glands, submandibular glands, and lacrimal glands, one had abnormalities in the parotid glands, 3 in the submandibular glands, and 7 in the lacri- mal glands. CONCLUSION： Lacrimal gland abnormalities occur more usually in AIP patients, which may be useful for the differentiation of AIP from pan- creatic cancer.
