Giant Gallbladder Revealed by Chronic Cholecystitis Gallstone: A Case Report and Review of the Literature.

We report here an extremely rare case of giant gallbladder and discuss diagnostic circumstances and different ethiopathogenic theories. A 53-year-old woman presented acute right hypochondrium pain. Ultrasonography showed a huge cystic mass with gallstones and a CT scan confirmed the diagnosis of giant gallbladder. Cholecystectomy was performed. Outcomes were uneventful and histopathological examination of the specimen confirmed the presence of chronic cholecystitis. Enlargement of the gallbladder is related to biliary retention. This enlargement is favored by the slow evolution of malignant pathologies. However, some benign situations have been reported in the literature, and giant gallbladder can occur in a benign situation even if its ethiopathogeny is not so clear.
