Multidetector-row CT diagnosis of cholecystocolic fistula

Spontaneous fistula formation between the gallbladder and colon is an unusual complication of calculous cholecystitis and may be difficult to diagnose clinically because of its non-specific clinical signs and symptoms. This report describes a case of spontaneous cholecystocolic fistula in a 68-year-old man complicated by peritonitis from chronic calculous cholecystitis that was diagnosed pre-operatively by multidetector-row CT (MDCT).
