Branch-duct type intraductal papillary mucinous neoplasms (BD-IPMNs) are premalignant lesions of the pancreas and are most often diagnosed incidentally. Compared with main duct type IPMNs, the clinical management of BD-IPMNs without or with main pancreatic duct (MPD) dilatation remains challenging. Following a suspicion of BD-IPMN, identifying the risk of high-grade dysplasia (HGD)/malignancy would help decide whether resection or surveillance is optimal. The current consensus guidelines for BD-IPMNs largely rely on imaging features, and various imaging predictors of HGD/malignancy and different therapeutic strategies have been proposed. However, which imaging features can better predict the patients who will benefit from surgical resection remains controversial.
