CECOVESICAL FISTULA OF INFLAMMATORY ORIGI N MIMICKING CECAL NEOPLASM

We describe a case of a caecovesical fistula in a 60-year-old woman ca used by an inflammatory tumour of a probably appendicular origin which mimicked cancer of the caecum. The patient, had a history of idiopath ic peripheral polineuropathy and chronic constipation. presented urina ry tract infection and fecaluria, without symptoms of appendicitis. At operation, a solid mass including the caecum and the fundus of the bl adder was found, and the appendix was not identified. In view of the n eoplastic appearance and the imposibility of separating the caecum fro m the bladder, <<en bloc>> right hemicolectomy and partial cystectomy were performed. The pathologic study showed the inflammatory nature of the lesion.
