RESUMO
Intramural duodenal hematoma (IDH) is a quite rare disese entity which results from the collection of blood and body fluid between mucosa and serosa. Various degrees of duodenal obstruction may be caused by IDH as it gradually enlarges and compresses the mucosa against the opposite side of duodenum. The most common cause of IDH is blunt abdominal trauma and the spontaneous IDHs are generally casused by coagulation disorder such as blood dyscrasia, anticoagulation treatment or pancreaticoduodenal aneurysm. The diagnosis is usually made by the typical imaging on abdominal computed tomographic scan with a previous history of blunt abdominal trauma. For spontaneous IDH without coagulation disorder, an abdominal angiogram may be considered to exclude vascular anomalies. Medical treatment is recommended unless the associated visceral injuries require immediate laparotomy. Here, we report a case of acute duodenal obstruction due to IDH which had resolved completely without an operative management.
