Overview

Gallbladder polyps are a common clinical findings occurring in 5% of patients who often have cross-sectional imaging for non-specific abdominal symptoms.

When encountering patients with gallbladder polyps, it is important to note what type of polyp is described. While “true” polyps are adenomatous, gallbladder polyps are often non-epithelial growths and, in fact, about 70% of polyps are cholesterol polyps that have no malignant potential.

Adenomas are uncommon and constitute approximately 8% of all gallbladder polyps. Less common polypoid lesions include gallbladder adenocarcinomas, inflammatory polyps, gallstones masquerading as polyps and heterotopic tissue.
