Adenomyomatosis of the gallbladder is an entity that is being recognized increasingly, chiefly by radiologists. The pathogenesis, pathology, and indications for surgery are not well understood. The clinical, radiological, and pathologic features supported a hyperplastic and degenerative disorder which should be distinguished from cholecystitis. Associated with these morphologic changes is a dyskinesia similar to that seen in diverticular disease of the colon. Follow-up studies after cholecystectomy have shown that over 90 percent of all patients were completely relieved of symptoms. Adenomyomatosis should be identified as a distinct entity, probably of a degenerative nature. Cholecystectomy is indicated and beneficial when the symptoms suggest biliary tract diseases.
