Inflammatory polyps of the gallbladder
Inflammatory polyps of the gallbladder are a subtype of gallbladder polyps, representing ~10% of polyps.
Thought to develop from chronic inflammation, with deposition of cholesterol in the gallbladder wall and mucosal irritation, leading to a fibrous reaction 2.
There is no evidence that they are a premalignant lesion.
- usually multiple and <10 mm
- variable echogenicity
- cannot be reliably differentiated from other subtypes of gallbladder polyp
