Rare Ileal Inflammatory Fibroid Polyp Causing Intussusception: A Case Report

Abstract

An inflammatory fibroid polyp (IFP) is a rare, benign tumor most commonly presenting in the gastric antrum (60–70%), followed by the intestines (18–20%). We present a case of intussusception due to an IFP. A middle-aged female was admitted with right iliac fossa pain and abdominal distention. A CT of the abdomen showed a 5 cm smooth, oval, fluid-like (24 HU), simple hypoattenuating lesion at the terminal ileum complicated with intussusception. An open laparotomy and end-to-end anastomosis were performed. The tumor was resected. Histopathological results showed an IFP. IFP can be identified on CT abdomen as oval, hypoattenuating, fluid like lesion, However, it is not specific and other differential diagnoses of bowel lesions should be considered. Histopathologically, it is rare that this lesion extends into the muscularis propria and subserosa.
