Gallbladder inflammatory polyps are a benign subtype of gallbladder polyps, representing ~10% of all polyps. They appear as a result of chronic inflammation (chronic cholecystitis).
For further details, please refer to the parental article on gallbladder polyps.
On this page:
Pathology
Gallbladder inflammatory polyps are thought to develop from chronic inflammation, with deposition of cholesterol in the gallbladder wall and mucosal irritation, leading to a fibrous reaction 2,3.
There is no evidence that they are a premalignant lesion 3.
Radiographic features
Ultrasound
- usually multiple and <10 mm
- variable echogenicity
- cannot be reliably differentiated from other subtypes of gallbladder polyp
- features of chronic cholecystitis might be evident
