CT and MRI imaging features of carcinoma of the duodenal papilla / 中华肝胆外科杂志

ABSTRACT

In this article,we reviewed the CT/MRI imaging features of carcinoma of the duodenal papilla in 15 cases.The characteristic CT and MR imaging findings of duodenal papillary carcinoma included mass in the descending part of the duodenum,the mass and duodenum wall showed a "target" sign or " diamond ring" sign;a ring-enhancing lesions around the distal end of the common bile duct/pancreatic duct,and thickening of the wall of the second portion of the duodenum near the papilla.The use of MPR MDCT images and MRI coronal images are very useful to show these imaging features as an aid in early diagnosis of carcinoma of the duodenal papilla.
