CT Findings of a Gastric Inflammatory Fibroid Polyp Manifesting as Unexpected Growth: A Case Report

cellular proliferations that originate from the submucosa, and are histologically composed of fibrous tissues, blood vessels, and an inflammatory cell infiltrate containing a high percentage of eosinophils within an edematous and collagenous stroma (1). IFPs are most frequently found in the gastric antrum and the small bowel (1). Although the pathogenesis of gastric IFPs remains uncertain, some authors have proposed that they result from immunological reactions to several irritations; in particular, they may be related to Helicobacter pylori infection (2, 3). Several reports on gastric IFPs have described its endoscopic findings; however, few have reported on its CT findings (1, 4). To the best of our knowledge, no previous report has been issued on the CT findings of a gastric IFP showing morphological changes. Here, we report the CT findings of a case of gastric IFP that demonstrated marked growth over a five month period.
