  "abstract": "Intraductal papillary neoplasm of the bile ducts (IPNB) is a premalignant epithelial lesion of the biliary tract. IPNB arising from the cystic duct is extremely rare. A man in his 70s presented with right upper quadrant abdominal pain with radiation to the right shoulder. Imaging studies revealed a small enhancing lesion in the gallbladder cystic duct, accompanied by features of acute cholecystitis. Macroscopic evaluation of the cholecystectomy specimen showed an intraluminal papillary lesion confined to the cystic duct. Histologic examination demonstrated intraductal papillary proliferation with high-grade dysplasia and focal invasion, consistent with IPNB with invasive carcinoma (pT1b). This case highlights the rare presentation of cystic duct IPNB with luminal obstruction and acute cholecystitis.",
