[Association of an appendicovesical fistula and an appendiceal adenoma. Case report]

Abstract

A new case of appendicovesical fistula is reported. A hundred cases of such fistula are described in the literature. Usually the origin is appendicitis. Cecal diverticulitis, cystadenocarcinoma or carcinoid tumours of appendix are other less common causes. In one case, association with neuroma of appendix is found. We report a case of appendicovesical fistula caused by papillo-villous adenoma of appendix. In this case, echography and cystoscopy were helpful in management of diagnosis and planning for the therapeutic approach. Only two other cases of benign tumour of appendix forming fistula are reported in the literature.
