case_images: Twenty-eight months after chemoradiotherapy, magnetic resonance imaging (MRI) revealed multiple recurrent tumors with muscle layer infiltration of the left lateral wall and the neck of the urinary bladder (T2-weighted image; Figures 1(a) and 1(b)).

case_images: T4a, with lymphovascular invasion, positive surgical margin, and skip lesions of the UC in the perivesical adipose tissue (Figure 2). Therefore, we decided to perform more careful observation of this patient without adjuvant chemotherapy.
case_images: Dynamic contrast-enhanced MRI showing LMC of the cerebrum, mesencephalon, and cerebellum (a). Infiltrating tumor cells can be identified along the cerebral cortex on T2 fluid-attenuated inversion-recovery imaging (b) (arrows).

case_images: Dynamic contrast-enhanced MRI showed LMC of the cerebrum, mesencephalon, and cerebellum (Figure 3(a)). Infiltrating tumor cells were identified along the cerebral cortex on T2 fluid-attenuated inversion-recovery images (Figure 3(b)).
case_images: T2-weighted MRI showing vestibulocochlear nerves metastasis (a) and cauda equina metastasis (b) (arrows).
