Ileo-Ileal Intussusception Caused by Inflammatory Fibroid Polyp in an Adult Female: A Case Report

Intussusception occurs when a segment of the intestine telescopes into an adjacent part, leading to obstruction and possible ischaemia. Although common in children, adult intussusception is rare and frequently associated with a pathological lead point. We report the case of a 62-year-old woman who presented with abdominal pain, vomiting, and constipation. Contrast-Enhanced Computed Tomography (CECT) revealed ileo-ileal intussusception with a suspected lesion measuring approximately 6 cm. Intraoperatively, a 3×3 cm serosal tumour was identified as the lead point. Resection and ileo-ileal anastomosis were performed, and histopathology confirmed the mass to be an Inflammatory Fibroid Polyp (IFP) with eosinophilic infiltration. This case highlights the importance of early diagnosis using imaging and the necessity of surgical intervention to avoid complications. Awareness of IFPs as rare causes of adult intussusception can guide timely and accurate clinical decision-making.
