Ultrasound findings in small bowel infarction.

A patient with small bowel infarction was studied using grey-scale ultrasound. The appearance was that of a lobulated abdominal mass consisting of smaller masses with a central sonolucent area and a peripheral echogenic rind. This is the reverse of what has been described in intramural intestinal hematoma, intussusception, and inflammatory and neoplastic bowel masses.
