Score: T2W/DWI/DCE: 5/5/+ PI-RADS 5
- MRI stage T3a (mT3a): bulge, broad contact, invasive
- Value of DCE: early enhancement, arterial curve-like
high probability of Gleason 4 component
- PI-RADS 5: internal invasive growth, >15 mm
Score: T2W/DWI/DCE: 5/5/+ PI-RADS 5

83 yr
PSA 13,2
PSAD 0,29
DRE T2R
Answer:
PI-RADS 5 in d.d.: granulomatous prostatitis (GP)
Always biopsy to exclude sign-PCa
T2W: Patchy organized chaos + some erased charcoal
DWI: Patchy areas of low ADC (minimal 467)
DCE: areas of central lack of enhancement
Diagnosis: GP + central necrosis

Sadly, many of us exhibit high Ego, high Euro, and low Empathy.
Let’s strive to restore the pyramid to its proper orientation
By doing so, we’ll create a far better world for all.
