Chronic epigastric pain in a middle-aged man.

Abstract

The objective of this article is to describe and show a number of imaging findings that are classical for an intussusception in an adult and discuss the clinical manifestations and associated findings. We also discuss the differential diagnosis of intussusception in an adult and the most likely causes. A malignant cause of intussusception is more likely when an intussusception involves the large bowel, in which case primary adenocarcinoma of the colon is the most prevalent. Therefore, surgical resection followed by careful pathologic analysis is typically indicated in nonresolving cases. Nevertheless, when intussusception is transiently diagnosed in an asymptomatic adult, follow-up is favored over surgery.
