Cholecystitis emphysematosa, sometimes called acute gaseous cholecystitis, pyopneumocholecystitis, or gas phlegmon of the gallbladder, is a rare form of acute, usually gangrenous, cholecystitis in which gas is found within the gallbladder lumen. This phenomenon was first reported as an operative finding by Lobingier1 in 1908. The first recorded preoperative roentgenogram diagnosis was made by Von Friederich2 in 1929. Since this time a few operative reports and reviews3-5 have occurred in the literature. As this phenomenon appears more commonly in diabetics, it is suggested that it will be more frequently encountered primarily associated with the aging diabetic population. The disease has been reported6 occurring between the ages of 32 and 76, but it most frequently occurs between the fifth and seventh decades and thus is a problem of a somewhat older age group than the average acute cholecystitis. The sex incidence is essentially the same as that
