A 58-year-old male patient presented with history of recurrent hematuria and pelvic pain. Axial T2 WI (a) showed intra-vesical soft tissue mass arising from dome and high left posterolateral bladder wall expressing intermediate signal intensity with infiltration of the muscle layer and perivesical fat. Axial DW-MRI (b1000) (b) showed restricted diffusion of the mass with infiltration of the perivesical fat. Axial ADC map (c) showed low SI of the lesion with ADC value = 0.85 × 10–3 mm2/s, consistent with high-grade tumor. Axial post contrast T1WI FAT-SAT (d) showed early heterogeneous enhancement of the mass with cystic degeneration and infiltration of the perivesical fat. Time-intensity curve (e) showed grade 3 curve with early enhancement and rapid washout. Multiparametric MRI features of low-grade stage T3 muscle-invasive urinary bladder carcinoma. Microscopic image of histopathology (f) demonstrated high-grade urothelial carcinoma which confirms the multiparametric MRI finding
