Adenomyomatosis Looks Like a Pearl Necklace

Focal and diffuse thickening of the gallbladder, Benign and noninflammatory pathology. Gallbladder adenomyomatosis is a benign alteration of the gallbladder wall characterized by excessive epithelial proliferation associated with muscle hyperplasia, resulting in thickening of the gallbladder wall. Excessive epithelial proliferation leads to epithelial folding in the underlying muscle layer with the subsequent formation of diverticular pockets lined with epithelium, the Rokitansky-Aschoff sinuses (SRA).
