Ileocolic Intussusception Secondary to Appendicular Mass in an Adult Patient: A Case Report and Radiological Approach.

Abstract

Intestinal intussusception is a condition determined as the telescoping of one portion of the bowel loops into the approximate distal portion. Intestinal intussusception is a fairly rare condition in the adult population and almost always secondary to the underlying pathology; the most common leading causes of intussusception in adults are neoplasms, accounting for up to two-thirds of the causes. However, appendicular pathology is an extremely rare leading cause. The clinical picture of an adult patient with bowel intussusception (BI) is uncertain and nonspecific; it varies from vague abdominal pain to clinical presentation of complications, such as signs of bowel obstruction or bowel perforation. Therefore, early access to imaging is the cornerstone for the early detection and establishment of the provisional diagnosis of BI. Herein, we report a case of ileocolic intussusception in an adult patient secondary to appendicular phlegmon; moreover, we propose a radiological approach to reach the diagnosis of intestinal intussusception in the adult age group.
