A 70-year-old male patient, presented hematuria, his PSA level was 38 ng/ml. a T2 WI high-resolution pelvic MRI: a well-defined lesion (2.2 × 1.2 cm) at the right PZ at the level of mid gland with an abnormal hypointense T2WI SI with irregular capsule. b DWI image showed restricted diffusion. c ROI on DTI image: (FA = 0.31), (MD = 0.55 × 10mm2/sec), d DTT map displays slightly disorganized fiber bundles without interruption that corresponds with intermediate grade prostate cancer. e Transrectal US and biopsy were done: an ill-defined suspicious hypoechogenic focal lesion at the left PZ (yellow arrow). f Histopathological biopsy: prostatic adenocarcinoma, moderately differentiated, combined Gleason score: (3 + 4 = 7). T2WI, T2-weighted imaging; FA, fractional anisotropy; DWI, diffusion-weighted imaging; DTT, diffusion tensor tractography. PZ: peripheral zone
