Table 1. Predictors of malignancy in branch duct IPMN.

Category	Sendai consensus	Fukuoka consensus
High-risk stigmata	Presence of mural nodules; MPD >6 mm; symptoms; positive cytology (cyst size >3 cm)§	Enhanced mural nodules; MPD ≥10 mm; jaundice associated with a cystic mass in pancreatic head
Worrisome features		Cyst size ≥3 cm; thickened enhanced cyst walls; MPD 6-9 mm; non-enhanced mural nodules; MPD stenosis with distal pancreatic atrophy; adjacent lymphadenopathy

^§, cyst size >3 cm is not an absolute indicator of malignancy until more evidences are available. IPMN, intraductal papillary mucinous neoplasm; MPD, main pancreatic duct.
