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
