A 69-year-old male suspected of having prostate cancer based on a high serum prostate-specific antigen (100.1 ng ml−1) level. All biopsy samples were positive in the 12 core systematic biopsies. Gleason score 4+4=8. Three-dimensional (3D) greyscale transrectal ultrasound shows ill-defined peripheral and transitional zone demarcation on the transverse, sagittal and coronal planes. 3D power Doppler sonography shows diffusely increased flow in the prostate gland.
