Most small<unk> s (less than 1 cm) are not cancerous and may remain unchanged for years. However, when small<unk> s occur with other conditions, such as primary sclerosing cholangitis, they are less likely to be benign. Larger<unk> s are more likely to develop into adenocarcinomas. Cholesterolosis is characterized by an outgrowth of the mucosal lining of the gallbladder into fingerlike projections due to the excessive accumulation of cholesterol and triglycerides within macrophages in the epithelial lining. These cholesterol<unk> s account for most benign<unk> s. Adenomyomatosis describes a diseased state of the gallbladder in which the gallbladder wall is excessively thick, due to proliferation of subsurface cellular layer. It is characterized by deep folds into the muscularis propria. Ultrasonography may reveal the thickened gallbladder wall with intramural diverticulae, called Rokitansky-Aschoff sinuses.
