Colosalpingeal fistula: a rare complication of colonic diverticular disease

Abstract.

Diverticular disease is a common condition in Western countries. The formation of inflammatory fistulae, usually from sigmoid colon to bladder or vagina, can be a feature of complicated cases of the disorder and is normally an indication for surgical intervention. We present a case of colosalpingeal fistulation occurring secondary to diverticulitis, a complication which, to our knowledge, has not been previously reported in the radiological literature. As in this instance, the initial clinical presentation of this problem can often be non-specific, with localising symptoms occurring later. In our case, barium enema examination allowed good demonstration of the fistulous communication before the more specific symptoms were clinically apparent.
