A 55-year-old male patient with acute onset of abdominal pain was examined. He had no apparent history of abdominal trauma or bleeding tendency. MRI showed three layered architecture, so-called "ring sign" distinctive of hematoma. MRI seemed to be very useful in non-invasively diagnosing intramural duodenal hematoma.
对一名突发腹痛的55岁男性患者进行了检查。他没有明显的腹部外伤史或出血倾向。磁共振成像（MRI）显示出三层结构，即所谓的血肿特有的“环形征”。MRI在非侵入性诊断十二指肠壁内血肿方面似乎非常有用。
