Fukuoka IPMN Fukuoka international consensus imaging features for intraductal papillary mucinous neoplasm

vigente

Categorias num relance

Cat.	Significado	Conduta	Risco	Fonte
no-risk-features	No worrisome features or high-risk stigmata Neither high-risk stigmata nor worrisome features present on imaging: a branch-duct IPMN below the worrisome-feature thresholds (cyst <3 cm, no enhancing mural nodule, main pancreatic duct <5 mm, no concerning secondary features).	Imaging surveillance rather than resection; the source describes risk-stratified follow-up of cysts without worrisome features or high-risk stigmata.	Lowest malignancy risk category among IPMN; managed by surveillance.	okfonte PMC8713311, Table 2 (revised Fukuoka 2017): absence of the listed worrisome features and high-risk stigmata.
worrisome-features	Worrisome features Worrisome features: cyst size >=3 cm; enhancing mural nodule <5 mm; thickened/enhancing cyst walls; main pancreatic duct 5-9 mm; abrupt change in main-duct caliber with distal pancreatic atrophy; lymphadenopathy; elevated serum CA 19-9; acute pancreatitis attributable to the IPMN; and cyst growth rate >5 mm over 2 years.	Further assessment, typically endoscopic ultrasound (EUS), rather than immediate resection; the presence of worrisome features prompts closer evaluation.	Intermediate malignancy risk warranting additional workup.	okfonte PMC8713311, Table 2: worrisome features 'Cyst size >= 3 cm; Acute pancreatitis (due to IPMN); Enhancing mural nodule >= 5 mm; Thickened and enhancing cyst wall; MPD dilation 5-9 mm; Abrupt change of MPD caliber with distal pancreatic atrophy; Presence of lymphadenopathy; Elevated serum CA 19-9; Cyst growth rate > 5 mm/2 yr'.
high-risk-stigmata	High-risk stigmata High-risk stigmata: obstructive jaundice in a patient with a cystic lesion of the pancreatic head; enhancing mural nodule >=5 mm; main pancreatic duct >=10 mm; (and high-grade dysplasia or cancer on cytology).	Surgical resection is recommended for surgically fit patients with any high-risk stigmata.	Highest malignancy risk category; resection advised.	okfonte PMC8713311, Table 2: high-risk stigmata 'Jaundice; Enhancing mural nodule >= 5 mm; MPD >= 10 mm' (plus 'HGD or cancer on cytology').
