Case Discussion
Adenomyomatosis of the gallbladder is a hyperplastic cholecystosis of the gallbladder wall. It is a relatively common and benign cause of diffuse or focal gallbladder wall thickening. Three morphological types of adenomyomatosis are described: fundal (localized), segmental (annular), and generalized (diffuse). It is most often an incidental finding and usually requires no treatment.
