Adenomyomatosis of the gallbladder
Updates to Case Attributes
This female patient had a CT made forto evaluate a totally different reason, namely renal cyst (seen on the left). Indeterminate gallbladder appearance was found with a suspicion of an inflammatory process or a tumor. Clinicians decided to evaluate this patient in abdominal mrMR with cholangiopancreatographic sequences.
Final diagnosis of gallbladder adenomyomatosis can be made with a very high rate of certainty noting the characteristic findings- intramural cystic diverticula with lumen narrowing without any nodular enhancing conentcontent (pearl necklace sign).

These are thin section axial plane T2WI fat saturated images as a part of abdomen examination made to evaluate gallbladder findings in a CT exam that was ordered to confirm benign character of a large renal cyst (on the left). WallThe wall of the fundus and distal body of the gallbladder is alterated bycontain multiple cystic intramural diverticula with lumen narrowing which give the characteristic pearl necklace sign appearance.
