[Intramural small-bowel hematoma due to anticoagulant therapy: a radiologic study; with regard to two cases]

We report two cases of spontaneous small bowel hematoma in two patients receiving long-term anticoagulant therapy. Plain abdominal film, ultrasound, CT-scan and oral barium examination were performed. Abdominal ultrasonography and CT-scan are in most cases relevant for the correct diagnosis of intra-mural small bowel hematoma. The diagnosis was based on the acknowledgment by the patient of anticoagulant drug consumption. Early diagnosis is crucial because most patients are treated nonoperatively with good outcome.
