Enterovesical fistulae secondary to benign or malignant bowel disease are not uncommonly reported in the literature. However,bladder malignancy as the primary pathology is exceedingly rare. We report a case of muscle invasive urothelial carcinoma of bladder with an enterovesical fistula to a loop of small bowel. The patient first presented with signs and symptoms of per rectal bleeding,haematuria,pneumaturia,faecaluria and rectal micturition. Her initial biochemistry test revealed significant metabolic acidosis with normal anion gap and hypokalemia. A computed tomography abdomen/pelvis with rectal contrast demonstrated an enterovesical fistula from the dome of bladder to a loop of small bowel. The patient underwent radical cystectomy with enbloc resection of a loop of involved ileum and sigmoid colon due to the intraoperative findings of the sigmoid colon adherent to the tumour. The published literature is reviewed,focusing on the incidence,diagnostic modality and treatment strategies available for this rare condition.
