Intracholecystic papillary neoplasm of the gallbladder is a rare and relatively new entity in the fifth edition of the World Health Organization classification of tumors of the digestive system. It mainly occurs in elderly women. It is an exophytic, granular, and friable mass seen in gallbladder mucosa, often mistaken clinically as sludge. We report a middle-aged female with abdominal pain and a vague mass in the right hypochondrium. A computed tomography scan of the abdomen and pelvis showed a heterogeneously enhancing lesion in the gallbladder lumen extending from the fundus to the neck, causing an irregular luminal obstruction. Histopathological examination of the cholecystectomy specimen showed features of intracholecystic papillary neoplasm of biliary and oncocytic type with low-grade dysplasia.
