Systematic transrectal ultrasound biopsy was performed, which showed a Gleason 3 + 3 prostate cancer in the left midgland. Multiparametric MRI was performed. A. T2-weighted imaging shows an ill-defined hypointense lesion in the transition zone at the left midgland (arrow). B. Apparent diffusion coefficient map shows a marked low signal (arrow). C. Diffusion-weighted imaging shows marked hyperintensity (arrow). This was graded as a Prostate Imaging-Reporting and Data System 4 lesion. MRI-ultrasound fusion targeted biopsy shows a Gleason 3 + 4 cancer. The patient was, therefore, ineligible for active surveillance based on baseline MRI.
