Figure 1: Case no. 1. (a) Axial T2-weighted image (T2WI), (b) sagittal T2WI, and (c) coronal T2WI demonstrate ill-defined mass infiltrating the posterior wall of the urinary bladder (UB) extending to the adjacent part of the left lateral wall measuring 8.5 cm in maximum diameter. It displays low signal intensity in T2WIs. It infiltrates muscular layers of the UB with areas of likely disruption posteriorly and is seen inseparable from the uterine body, cervix, and upper vagina. (d) Diffusion-weighted image shows restricted diffusion with evidence of focal invading the perivesical fat planes along the left posterolateral wall of the UB. (e) Axial postcontrast T1-weighted image shows heterogeneous postcontrast enhancement.
