 note = {We experienced a case of intramural duodenal hematoma that was caused by a blunt trauma toward the upper abdomen in a 33-year-old man. Contrast-enhanced computed tomography (CT) was considerably effectual in diagnosis, visualizing a cystic lesion located at the upper second portion of the duodenum. Duodenography showed a so-called coiled spring appearance, and endoscopy revealed a tumor that was covered by normal duodenal mucosa and obstructed the whole duodenal lumen. We employed a conservative therapy in this case. The patient was discharged after 50 days hospitalization without any serious complications.},
