Sonographic appearances of conglomerated polyps (giant polyposis) in patients with Crohn's disease

Giant polyposis is a rare presentation of Crohn's disease (CD) of the colon and can be misdiagnosed as colon cancer. To our knowledge, the sonographic characteristics of conglomerated polyps in colonic CD have not been published. The purpose of this article is to describe sonographic findings in 3 patients with giant polyposis and evaluate the contribution of sonography in establishing this diagnosis. We conclude that sonography can facilitate the diagnosis of giant polyposis in CD by demonstrating associated findings in the large and small bowels that are suggestive of CD. © 2000 John Wiley & Sons, Inc.
