Acute Intestinal Intussusception in Adults Caused by an Inflammatory Fibroid Polyp: A Case Report

The inflammatory fibroid polyps (IFPs) are rare benign lesion originating in the submucosa of the digestive tract [1]. Its incidence is low, ranging between 0.6 and 2% [2]. Localization in the small intestine accounts for only 18% of cases [3], frequently presenting as acute intestinal intussusception. We report a case involving a 61-year-old woman with a history of cesarean section, presenting with diffuse abdominal pain, cessation of bowel movements and gas, and food-related vomiting. Physical examination revealed slightly distended abdomen and pelvic tenderness. Imaging studies demonstrated mechanical bowel obstruction due to terminal ileoileal intussusception with regular circumferential thickening of the invaginated bowel loops without signs of ischemia. Histopathological examination with immunohistochemical analysis confirmed the diagnosis of an inflammatory fibroid polyp without evidence of malignancy.
