Small mesenteric hematoma following blunt abdominal trauma as early sign in computed tomography of occult small bowel perforation-report of 2 cases.

Blunt abdominal trauma can lead to mesenteric injuries, which are not an uncommon but often underestimated finding on the initial computed tomography (CT) scan. Only small mesenteric hematomas, which are shrinking in short-term follow-up CT examinations, do not require surgery. We present two cases where subtle mesenteric hematoma was one hint on the admission scan for subsequent small bowel perforation. So it can be a relevant finding and should prompt early CT follow-up imaging, even in asymptomatic patients. This will enable early diagnosis and reduction in morbidity and mortality.
