Synovial sarcoma of the prostate in a 26-year-old man, with a serum prostate-specific antigen level of 1.14 ng/mL. a, b T1-and T2-weighted imaging show a heterogeneous signal mass compressing the prostatic urethra and the left lobe of the prostate, with an incomplete, low T2 signal intensity pseudocapsule (arrowheads on b) and irregular areas of hemorrhagic and necrotic changes (☆). c DWI at a b-value of 1200 s/mm2 shows a high signal intensity of the solid area and low signal intensity of the cystic area of the mass (☆). d Coronal fat-suppressed T2WI shows the mass compressing the prostatic urethra and the left lobe of the prostate (arrowheads), compressing and invading the right seminal vesicle (arrow). e DCE imaging shows heterogeneous enhancement of the lobulated mass invading seminal vesicles (white arrow). Note the residual tissue of the left seminal vesicle (black arrow)
