Rokitansky-Aschoff sinuses, also entrapped epithelial crypts, are diverticula or pockets in the wall of the gallbladder. They may be microscopic or macroscopic.

Histologically, they are outpouchings of gallbladder mucosa into the gallbladder muscle layer.

They are not of themselves considered abnormal, but they can be associated with cholecystitis.

[edit] Causes

They form as a result of increased pressure in the gallbladder and recurrent damage to the wall of the gallbladder. They are associated with gallstones (cholelithiasis).
