From: Prostate cancer arising in ectopic prostatic tissue within the left seminal vesicle: a rare case diagnosed with multi-parametric magnetic resonance imaging and magnetic resonance imaging-transrectal ultrasound fusion biopsy

a-b Pre- and post-contrast fat-saturated T1-weighted (T1W) imaging of the prostate gland (arrowhead) and left seminal vesicle (arrow) reveal that this lesion demonstrated abnormal perfusion on dynamic contrast enhancement (DCE). c Computer-aided detection (CAD) confirms abnormal perfusion pattern of the lesion in the left seminal vesicle, which demonstrates early enhancement with partial washout and colorimetric stratification of both indeterminate/suspicious (‘green’) (dashed arrow) and highly suspicious patterns (‘red’) (solid arrow). The hyperperfused lesion in the left central zone with highly suspicious enhancement on CAD (asterisk) demonstrated relative hypointensity on T2W imaging with thin, circumscribed hypointense periphery, and no diminished diffusivity, compatible with a hyperplastic (BPH) stromal nodule that was later confirmed as benign on MR imaging-TRUS fusion biopsy
