摘　　要：Ileus from an impacted gallstone in the duodenum or any other part of intestine is a rare complication of cholelithiasis. When a gallstone impacted in the distal stomach or in the duodenum, it is called Bouveret＇s syndrome, a rare form of gallstone ileus. Small bowel ileus caused by gallstone has become more and more common recently due to popular usage of computed tomography （CT） and magnetic resonance imaging （MRI）. In the past, imaging diagnosis relied primarily on conventional radiography and contrast-enhanced fluoroscopy. CT has subsequently been shown to be quite useful for this diagnosis. Recently, MR cholangiopancreatography （MRCP） has emerged as a valuable noninvasive technique for evaluation of biliary disease. Here we described the CT, MRCP and gastroenterography findings in two patients with unusual form of gallstone ileus （GI）, one is Bouveret＇s syndrome and the other is negative gallstone-induced ileus. Few reports about GI with angiografin and MRCP findings of Bouveret＇s syndrome has been published.Ileus from an impacted gallstone in the duodenum or any other part of intestine is a rare complication of cholelithiasis.
