MR images of a 64-year-old man with prostate-specific antigen progression (PSA serum level 0.62 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 coronal T2-weighted fast spin-echo (4110/114) image showing a unilocular, thin walled hyperintense cystic-like mass at the obturator lymph nodes location. d Axial post-contrast T1-weighted fat saturated 3D FLASH (VIBE) image showing no signs of enhancement of the cystic mass. e Axial ADC map reconstructed from images obtained at b values of 0, 500 and 1000 s/mm2 show a bright area corresponding to the cystic mass seen on T2-weighted images. These findings are consistent with lymphocele (white arrows)
