The corresponding transversal T2w MRI image shows a low-signal-intensity mass (arrow) (B). Photomicrograph from a tissue cross section obtained after RP. The tumoural lesion on the right is outlined (blue dots) (C) . Fusion of the transverse T2w MRI image with the corresponding tissue cross section (D).
