Bulging duodenal papilla

Dr Francis Fortin and Radswiki et al.

Bulging duodenal papilla​ is a conical or cylindrical protuberance at the medial aspect of the descending or horizontal duodenum at the site of the sphincter of Oddi. It is a finding on small bowel follow-though (and endoscopy) and has a relatively long differential. On cross-sectional imaging, the underlying cause is usually seen before the effect on the papilla.
