Key findings:
- in T2 moderate hypointense left posteromedial and posterolateral peripheral zone with diffusion restriction and broad capsular contact and irregularity (red arrows)
- the indistinct margin of the pseudocapsule (green arrowhead)
- tumour extension along the ejaculatory ducts into the seminal vesicles above the base of the prostate (blue arrowheads).
Findings from the MRI of the prostate are illustrated on a map.
Biopsy results:
Histology of the US-guided systematic biopsy 4 months before the MRI showed a high-grade acinar adenocarcinoma (modified Gleason score 4+3=7b within five cores and 3+4=7a within one core) of the left lobe and a low-grade acinar adenocarcinoma (modified Gleason score 3+3=6) within one core taken from the right posteromedial mid gland. The five remaining biopsy cores were negative.
The results of the systematic biopsy are illustrated.
