The correct answer is  Adenomyomatosis is a type of hyperplastic cholecystoses, characterized by a benign proliferation of gallbladder surface epithelium with glandlike formations, extramural sinuses, transverse strictures, and/or fundal nodule ("adenoma" or "adenomyoma") formation. The classic appearance is focal wall thickening in the gallbladder fundus. The presence of cystic spaces and echogenic foci with "comet tail" reverberation aifact is diagnostic of adenomyomatosis.
