A 54-year-old male patient who underwent TURBT and was confirmed as Bladder inverted papilloma. a Sagittal reconstruction excretory phase image showed the lesion was located at the Bottom wall, the junction between lesion edge and bladder wall was smooth (arrow), the maximum transverse diameter of this lesion was 1.56cm, the maximum longitudinal diameter was 1.38cm (Transverse diameter/longitudinal diameter=1.13 ) and the tumor-wall interface was 0.97cm (yellow curve). b The non-enhanced CT value of this lesion was 32.71HU. c The arterial phase CT value of this lesion was 59.69HU, the arterial reinforcement rate was 0.82 ([59.69-32.71]/32.71)
