Intussusception in adults is rare. It is estimated to account for only 5% of all intussusceptions and causes only 1% of all bowel obstructions and 0.003-0.02% of all hospital admissions [1]. About 90% of intussusceptions in adults are caused by a definite underlying disorder such as a neoplasm or by a postoperative condition [2]. However, neoplasm is the most common cause and is found in approximately 65% of adult cases [3]. Malignant tumors are more common than benign tumors in the colon, although the reverse is true in the small bowel. In this article, we describe the characteristic radiologic features of intussusception according to location and cause and correlate these with the pathologic findings.
