We present a case of a 60-year-old woman with chronic lower abdominal pain and green urine. Further workup revealed a cholecystovesicular fistula (CVF), a newly coined term to indicate a fistula between the gallbladder and the urinary bladder. The CVF was treated surgically. The pathophysiology of CVF is thought to result from gallbladder perforation into the liver. Over time, a tract forms inferiorly until it meets another organ, in this case, the urinary bladder. This later complication of the gallbladder disease joins the broader spectrum of cholecystic fistulas. To our knowledge, a CVF has never been reported in the literature.
