A case of ileocecal inflammatory fibroid polyp (ifp) that presented as an invagination-like image with colon diverticulitis

Abstract

This patient was a 53-year-old man with pain and a right lower quadrant mass that was first noted in April 2009. Colon cancer was suspected on abdominal echography. On CT, the presence of metastases was suspected given the visualization of intraabdominal lymphadenopathy as well as multiple abdominal wall masses and left lung involvement. CF revealed bulky polyps in the ascending colon. Moreover, because the Barium enema showed multiple diverticula and an ileocecal stenosis in the same lesion, the patient was hospitalized ; a type 5 progressive colon cancer was suspected. After repeat CF and Barium enema studies, the cancer still could not be identified. However, his abdominal pain did not improve ; and abdominal CT showed possible invagination. The patient had an ascending colon resection and a small intestine segmental resection. On pathology, the ileocecal IFP resulted from inflammation of the colon diverticulitis, and IFP presented as an invagination on imaging.
