85-year-old male with history of prostate cancer treated with brachytherapy 10 years ago now with pelvic pain and dysuria. PELVIS:PROSTATE/SEMINAL VESICLES: Multiple small signal voids are present within the prostate likely representing brachytherapy seeds. There is a single small signal void located within the left periprostatic fat, but this is equivocal. BPH.BLADDER: Mildly trabeculated bladder wall likely the result of chronic outlet obstruction.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: Right groin skin scarring.
Mild findings of chronic outlet obstruction likely from BPH. Majority of brachytherapy seeds appear to be within the prostate gland, although there is suggestion that one seed may be located within the left periprostatic fat, however this is equivocal given susceptibility of MRI to artifact. Please note that CT is more sensitive to evaluate more exact location of brachytherapy seeds.
