Colosalpingeal fistula: a rare complication of colonic derverticular disease

Diverticular disease is a common condition in Western countries. The format ion of inflammatory fistulae, usually from sigmoid colon to bladder or vagi na, can be a feature of complicated cases of the disorder and is normally a n indication for surgical intervention. We present a case of colosalpingeal fistulation occurring secondary to diverticulitis, a complication which, t o our knowledge, has not been previously reported in the radiological liter ature. As in this instance, the initial clinical presentation of this probl em can often be non-specific, with localising symptoms occurring later. In our case, barium enema examination allowed good demonstration of the fistul ous communication before the more specific symptoms were clinically apparen t.
