Inflammatory fibroid polyp in Crohnʼs disease revealed by ileoileal intussusception: Case report and review of the literature

To the Editor: Inflammatory fibroid polyps (IFP) are rare, benign, submucosal lesions of the gastrointestinal tract. They were first described occurring in the stomach; however, their distribution is universal.1 Intussusception and intestinal obstruction are symptoms of lesion located in the small bowel.2,3 The simultaneous occurrence of active inflammatory bowel disease such as Crohn's disease (CD) with such lesions has rarely been reported and the exact etiopathogenetic relationship between both entities remains unclear.3,5 The present case report describes a patient with CD who presented acute obstruction symptoms due to an IFP located in the terminal ileum. A 22-year-old male patient was referred for clinical small bowel obstruction with crampy abdominal pain, nausea, and vomiting. This patient presented a 2-year history of left colonic and perineal CD treated with infliximab. Physical examination revealed a distended abdomen with tenderness on palpation and abdominal x-ray showed dilated small bowel segments. Computed tomography (CT) scan suggested ileal intussusception, showing proximal small bowel distension with thickening of terminal ileal segment with a concentric ring or “target” aspect.
