Visualization of the longitudinal fold of the duodenum by computed tomography.
The longitudinal fold of the duodenum can be visualized by computed tomography (CT). Visualization of the fold helps localize the hepatopancreatic duct entrance into the duodenum. Many pathological processes of the head of the pancreas such as pancreatitis or malignancy can produce swelling involving the longitudinal fold, which can be visualized by CT.
