prostate stromal tumor of uncertain malignant potential

Differential

diagnosis of uncommon prostate diseases: combining mpMRI and clinical information. Prostate stromal tumor of uncertain malignant potential in a 39-year-old man with a normal serum PSA level of 1.780 ng/mL. a Axial T2WI shows a well-circumscribed nodule with heterogeneous signal and an incomplete capsule (arrowheads) located in the left PZ of the prostate and compressing the extra-prostatic tissue. b DWI shows hypointensity, indicating no restricted diffusion of the nodule. c–f Axial DCE imaging at 30 s (c), 60 s (d), 120 s (e) and 180 s (f) after contrast injection shows the early and gradual enhancement of the nodule

diagnosis of uncommon prostate diseases: combining mpMRI and clinical information. Prostate stromal tumor of uncertain malignant potential in a 33-year-old man with a normal serum PSA level of 1.080 ng/mL. a Axial T2WI shows a 2.7-cm nodule with heterogeneous signal in the TZ of the prostate surrounded by a capsule-like hypointense rim (arrowhead). b, c DWI and ADC maps show remarkably restricted diffusion of most of the nodule (☆). d–f Axial DCE imaging at 30 s (d), 60 s (e) and 120 s (f) after contrast injection shows early and gradual enhancement of the nodule containing non-enhanced areas inside the tissue (arrow)
