Gastric concretion forming around a suture nidus and mimicking a gastric polyp on radiographs.
A small gastric mass was detected by upper GI X-ray series and found at endoscopy to be a concretion hanging from a suture at a previous gastrostomy site. The suture was clipped and the concretion was removed endoscopically. Sutures protruding into the gastric lumen may serve as a nidus for the formation of concretions and because of their fixed position, these masses may mimic neoplasms on upper GI X-rays.
