Adenomyomatosis of the gall bladder: This is often an incidental finding on cholecystography. There is thickening of the muscle layers and the gall bladder mucosa. Usually no treatment is indicated.

Gallbladder polyps are due to an elevation of the gallbladder mucosa, which protrudes into the gallbladder lumen. Polyps can be divided into polyps and pseudopolyps. Pseudopolyps have no malignant potential and thus require no further intervention or follow-up. Polyps, including those classified as adenoma and adenocarcinoma, warrant surgical resection. The occurrence of gallbladder polyps among adults has been estimated to be 5%, and of these, 5–30% are considered true polyps [7,8] (Figure 1). Features that predict malignant disease include the following: polyp size ≥ 10 mm, solitary or sessile mass, associated gallstones, patient age over 50 years, rapid polyp growth, primary sclerosing cholangitis and positive fludeoxyglucose (FDG) uptake on positron emission tomography (PET) [2,8–10]. For patients with primary sclerosing cholangitis, surgical intervention is recommended regardless of polyp size, as even small polyps have been shown to carry malignant potential in this patient group [1,8,11]. Ethnicity and geography are also factors to consider, as a higher incidence of gallbladder cancer is observed in Latin America and Asia and a lower incidence is observed in the United States and in Western and Mediterranean Europe [2,12,13]. Gallbladder wall thickening can consist of adenomyomatosis, chronic cholecystitis and porcelain gallbladder (Figure 2).

There are a few benign gallbladder morphologies which may present macroscopic abnormalities. Some gallbladders present with Rokitansky-Aschoff sinuses also known as adenomyomatosis (Figure 3(a)), which is a benign condition and is characterised by pseudodiverticula of the gallbladder reaching into lamina muscularis as a result of hyperplasia and herniation into the gallbladder lumen [13]. Distinguishing between these sinuses and a possible (pre-)malignancy can be challenging.
Is there a role for growth status in distinguishing gallbladder adenomas from cholesterol polyps? – A retrospective study based on 520 cholecystectomy patients

Figure 1 summarizes the pathological diagnoses of all 581 GPs. Cholesterol polyps were the most common type of GPs [441/581 (75.9%)]. Non-cholesterol benign polyps consisted of 57 patients with adenomyomatosis, hyperplastic polyps, and inflammatory polyps. In terms of neoplastic polyps, adenomas constituted 95.2%, and the prevalence of adenocarcinoma was only 4.8%.
