The evolving role of multi-parametric MRI in the evaluation of bladder cancer: Revealing what lies beneath the surface.

Abstract Conventional staging for bladder cancer involves CT and TURBT, and is thought to understage up to fifty-percent of T1 tumours. This report details the case of a 64-year-old male who whilst on cystoscopic surveillance for high grade bladder cancer, underwent a multi-parametric MRI Bladder due to clinical suspicion of occult muscle invasive disease. Despite minimal urothelial changes at cystoscopy, MRI demonstrated a well-defined T3 lesion. The patient proceeded to radical cystectomy and final pathology verified the MRI findings. The role of MRI in bladder cancer is yet to be defined but should be considered if clinical suspicion for understaging exists.
