Inflammatory fibroid polyp presenting with intestinal invagination: Sonographic and correlative imaging findings

We report a case of a large inflammatory fibroid polyp of the small bowel presenting with intussusception in a 22‐year‐old man. Sonography demonstrated a solid, mobile, homogeneous, echogenic mass surrounded by the typical mural layers of an invaginated ileum. CT demonstrated a well‐defined intraluminal solid mass with an attenuation of 17 HU. The pathologic diagnosis after segmental ileal resection was ileal inflammatory fibroid polyp. © 1999 John Wiley & Sons, Inc. J Clin Ultrasound 27:89–91, 1999.
