Filiform Polyps

Filiform (thread-like) polyposis refers to the characteristic radiographic finding of multiple slender, finger-like filling defects seen on contrast studies (from the esophagus to the colon) in patients with inflammatory bowel disease.

Filiform polyps are true polyps consisting of submucosa and mucosa. Also called postinflammatory polyps, they are seen in the healing phase of Crohn disease or ulcerative colitis. The background mucosa is nearly always normal in appearance without evidence of acute inflammation.
