The formation of gas in such instances is usually due to the presence of gas-forming organisms within the gallbladder and conditions favorable to their growth.
Among the many acute intra-abdominal conditions which produce clinical problems acute pneumocholecystitis is relatively rare. The rarity of this condition has been pointed out by most authors writing on the subject. In 1956 LaCour and O'Neil2 were able to collect only 37 cases of acute pneumocholecystitis from the literature and added 1 of their own cases; since then no additional cases have been reported.
