Intussusception is rare in adult and usually caused by organic lesions, although there is a significant number of so-called idiopathic cases. The diagnosis of intussusception have been made by plain abdomen, barium enema and small bowel series. But recently ultrasound and computed tomography make a contribution to diagnose intussusep-tion. Computed tomography is not the primary means for evaluating a gastrointestinal tract abnormality but also provides yaluable informations in evaluating disorders affecting the hollow viscera of the alimen-tary tract. Computed tomography image of intussuseception demonstrates a whirl like pattern of bowel loops separated by fatty stripe correlating to the intestinal walls. Abdominal ultrasonogram was used as the initial diagnosic test in 2 cases out of total 4 cases, with abdominal mass of unknown cause. It revealed a typical pattern, composed of a round or oval mass with central dense echoes and peripheral poor echoes. We report 4 all cases of intussusception in adult who were performed by computed tomography and/or ultrasound. All cases were correlated with barium enema examination and / or surgical reports.
