More than a century ago, Rokitansky* mentioned hernia-like outpouchings of the gall-bladder mucosa. He described them as sometimes numerous and usually very small, commonly having narrow openings, and at times containing small concretions. Halpert,3 in 1927, declared these formations identical with the structures described by Aschoff in 1905 as Luschka's ducts and named them Rokitansky-Aschoff sinuses.

These diverticula may extend to the muscular layer of the gall-bladder wall, may penetrate into the intermuscular lacunae, or may progress through the muscular wall into the underlying connective tissue, even reaching the serosa occasionally. Although structurally similar to diverticula of the small intestine, colon, and urinary bladder, they differ in their tendency toward folding and branching, a characteristic ascribed to the particular construction of the gall-bladder wall. Pathologicoanatomic study has demonstrated that these invaginations are more numerous, appreciably deeper, and more developed in chronically inflamed gall bladders than in normal gall bladders
