MR images of a 64-year-old man with prostate-specific antigen progression (PSA serum level 0.75 ng/mL) after radical retropubic prostatectomy, with suspected local recurrence. a Axial T2-weighted fast spin-echo (6200/112), b axial T2-weighted fat saturated fast spin-echo (8300/112) and c sagittal T2-weighted fast spin-echo (4640/112) show a solid tissue on posterior perianastomotic location in front of the rectal wall at about 40 mm from the ureteral meatus, which is slightly hyperintense compared to pelvic muscles (white arrows). d Axial Gradient-echo T1-weighted image and e Gradient-echo T1-weighted subtracted image showing a remarkable enhancement of the pathological tissue f Axial ADC map reconstructed from images obtained at b values of 0, 500 and 1000 s/mm show a dark area corresponding to the abnormal hyperintense tissue seen on T2-weighted images (black arrow). All these findings are consistent with local recurrence
