Although diverticulosis of the gallbladder is not a new pathologic entity, the clinical and radiographic picture of the disease deserves periodic re-emphasis. A perplexing problem may thereby become clarified and a dilemma in treatment resolved.
In the pathologic review by Robertson and Ferguson,1 it was noted that Luschka first described the lesions of diverticulosis of the gallbladder but thought them to be glands. It has since been established that the lesions are false diverticula which correspond to those found at the pharyngo-esophageal junction and in the colon and urinary bladder. In the gallbladder they are generally small and multiple. The diverticula themselves are intramural, and their formation is probably related to the unique structure of the gallbladder.2 Mucosal plicae form recesses in the gallbladder mucosa. Unphysiologic increases in intraluminal pressure in the gallbladder may then lead to pulsion diverticula in the relatively loose stroma of the gallbladder wall.
