Magnetic resonance imaging (MRI) findings of the prostate tumor. A Axial T2-weighted image showing the tumor located in the right peripheral zone of the prostate with heterogeneous iso- to hyperintense signal and surrounding low signal intensity pseudocapsule (yellow arrowheads). In particular, the low signal intensity area in the posterior part of the tumor is indicative of fibrotic components (white arrow). B Axial diffusion-weighted image showing the tumor as areas of markedly high signal intensity (yellow arrowheads). C Axial dynamic contrast-enhanced MR image showing a weakly and gradually enhanced solid part of the tumor (yellow arrowheads)
