| [ Summary ] | Intraductal papillary mucinous neoplasm (IPMN) is often detected by cross‒sectional imaging. Most branch‒duct IPMNs can be followed‒up without cyst resection ; however, it is important to consider the incidence of IPMN‒related cancer such as IPMN‒derived and IPMN‒concomitant cancer during follow‒up of IPMN. A mural nodule is a predictor of malignant IPMN, and there are several reports that evaluate the presence and/or size of the mural nodule for differential diagnosis of malignant‒IPMN from non‒malignant IPMN. Previous reports also mentioned that the prognosis of IPMN‒related cancer is better than ordinary pancreatic ductal adenocarcinoma. For early detection of those tumors, optimal follow‒up methods based on evidence are needed. In particular, endoscopic ultrasound is useful for early detection of IPMN‒derived and IPMN‒concomitant cancer during follow‒up of IPMN. | |
