[Enterovesical fistula secondary to leiomyosarcoma].

We report an unusual case of an enterovesical fistula caused by leiomyosarcoma infiltrating the intestinal wall and urinary bladder. The patient had previously presented recurrent urinary tract infection for one year. Although he has residual tumor, so far this elderly patient has survived for three years post-operatively without further antineoplastic treatment.
