Core Tip
Core tip: Branch-duct intraductal papillary mucinous neoplasms are a frequent incidental finding. The management of these lesions is challenging because of the need to balance low but concrete risk of developing malignancy over time versus costs of prolonged follow-up procedures. In this retrospective study, we showed high rate of imaging evolution (44.4%), with 8.3% of patients developing alert findings prompting further diagnostic steps, though there were no final diagnoses of malignancy. Since there were no clinical or imaging predictors of alert findings, our results suggest that prolonged follow-up is useful, but might be significantly delayed with minimal risk of missing malignancy.
