Prostatic stromal sarcoma in a 41-year-old man with a normal serum PSA level of 0.784 ng/mL. a Axial T2WI shows an oval mass occupying the prostate with heterogeneous hyperintensity, an incomplete hypointense capsule and compressing the bladder (arrowhead). b, c Axial DWI and ADC maps show cystic areas occupying the majority of the mass (☆), but containing focal solid components with remarkably restricted diffusion (arrow). d Axial fat-suppressed T1WI shows the mass containing a slightly high signal intensity, which suggested a hemorrhagic change (arrow). (e–f) Axial DCE imaging (e) shows that the mass had diffuse but no enhancement of the cystic components (f, curve 2) accompanied by a gradual moderate enhancement restricted to the solid components (f, curve 1)
