Background: Cystitis cystica, previously thought to be premalignant condition or associated with malignancy, is actually a benign condition. It may present with lower urinary tract symptoms, abdominal pain or haematuria. The exact aetiology is unknown. Cystitis cystica may cause chronic bladder outflow obstruction resulting in hydronephrosis and hydroureter.

Case Presentation: A 53-year-old male was referred to emergency department with incidental finding of deranged renal profile. Physical examination was unremarkable. Ultrasound revealed gross hydronephrosis and hydroureter with bladder wall trabeculae suggestive of chronic bladder outlet obstruction. Cystoscopy revealed small tumour over the bladder neck. It was subsequently confirmed to be a case of cystitis cystica.

Conclusions: Cystitis cystica can only be confirmed by histopathology. Unless confirmed by histopathology examination, all suspicious tumours should be treated as malignancy until proven otherwise.
