Pearl necklace sign

The pearl necklace sign occurs in adenomyomatosis of the gallbladder, on both oral cholecystograms and MRCP. It represents the contrast / fluid-filled intramural mucosal diverticula (Rokitansky-Aschoff sinuses); lined up, these are reminiscent of pearls on a necklace. It is synonymous with the CT rosary sign.

It is said to be highly specific (92%) for the diagnosis of adenomyomatosis, however it has limited sensitivity, present in ~70% of cases 1.
