Abstract
AIM: To summarize ultrasononographic findings 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, parapancreatic lymph nodes were enlarged, echoes of the kidneys were evenly distributed, and the parotid glands, submandibular glands and lacrimal glands mimicked symptoms associated with Sjogren's syndrome.
RESULTS: Of 16 patients, 6 had dilated pancreatic ducts, 8 had dilated bile ducts, 6 had thickening 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 lacrimal glands.
CONCLUSION: Lacrimal gland abnormalities occur more usually in AIP patients, which may be useful for the differentiation of AIP from pancreatic cancer.
