TEACHING POINTS

Incidental gallbladder (GB) polyps are common, seen in 3-6% of the general population, often benign cholesterol polyps. Few GB polyps (6%) are neoplastic (intracholecystic papillary neoplasm, ICPN). While ICPNs have malignant potential, malignant transformation is believed rare. GB cancers also typically arise from flat dysplastic epithelium, not polyps. Yet the concern a small polyp may harbor a future or early neoplasm has led past guidelines to suggest relatively aggressive management; recent studies show significant overtreatment of predominantly benign GB lesions.In 2021 the Society of Radiologists in Ultrasound (SRU) convened a multidisciplinary committee to review current literature and construct updated guidelines for the management of incidentally detected GB polyps. The SRU Guidelines, to be published in 2022 (Radiology), stratify risk into three categories: Extremely Low, Low, and Indeterminate Risk. Clinical examples and common questions will be addressed.
