A 63-year-old man with hematuria for 6 months. A biopsy revealed high-grade urothelial carcinoma. The patient underwent 2 cycles of neoadjuvant chemotherapy followed by transurethral resection of the bladder tumor. A Axial T2-weighted image shows an exophytic tumor extending to extravesical fat on the right side of bladder. B Axial diffusion-weighted image (b = 1000) shows high-signal-intensity sessile tumor with low-signal-intensity thickened inner layer. C Apparent diffusion coefficient image shows low-signal-intensity sessile tumor with high-signal-intensity thickened inner layer. D Axial contrast-enhanced image shows early enhancement tumor with continuous submucosal linear enhancement (arrows). The final VI-RADS score was 2 for all readers. Histopathology confirmed a non-muscle-invasive bladder cancer
