Hypertrophic verumontanum of a 66-year-old man with prostate-specific antigen progression (PSA serum level 0.75 ng/mL) after radical retropubic prostatectomy. a Axial T2-weighted fast spin-echo (6330/115), b axial T2-weighted fat saturated fast spin-echo image (8450/115) and c sagittal T2-weighted fast spin-echo (5000/114) show a small tissue at the bladder neck location, which is slightly hyperintense compared to pelvic muscles (arrow). d Axial Gradient-echo T1-weighted subtracted image showing no signs of enhancement of the suspicious pathological tissue detected on T2-weighted images. 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 abnormal hyperintense tissue seen on T2-weighted images, which is a finding suggestive for the absence of restricted diffusion phenomena. f Photomicrograph from biopsy specimen showing verumontanum
