An appendicular mass mimicking a bladder tumour.

We present a case of an appendicular mass mimicking symptoms of a bladder tumour in a 27-year-old female. The patient initially presented with a 5-month history of intermittent lower abdominal pain associated with dysuria, anorexia and weight loss. Cystoscopy revealed an erythematous urothelium with the appearance of a solid mass bulging into the bladder posteriorly. Urothelial biopsies were negative and computerised tomography showed a soft tissue mass extending from the right superior aspect of the bladder and abutting the distal ileum. At laparoscopy an appendiceal mass adherent to the bladder was found. The symptoms later resolved and she is well at follow-up.
