Intussusception associated with Salmonella typhimurium enterocolitis.

Abstract

Intussusception in the adult is unusual, and its etiology is mostly neoplastic. In most cases of intussusception, a polypoid tumor located in the terminal ileum invaginates within the cecum. We described an unusual case of adult intussusception associated with Salmonella typhimurium enterocolitis. Preoperative diagnosis of intussusception in the ileocecal region was made by ultrasonography, and the ileocecal region containing the mass in the cecum, causing the intussusception, was resected. Histological features of the mass included an edematous focal wall thickening. Later, the diagnosis of S. typhimurium enterocolitis was made by the preoperative stool cultures. This case demonstrated intussusception as a complication of S. typhimurium enterocolitis. It is worth noting that S. typhimurium enterocolitis is in fact a potential cause of intussusception.
