Seminal vesicle ischaemia. Image from a 72-year-old patient with lower urinary tract symptoms due to a large BPH (120 mL). a Axial contrast-enhanced T1-weighted MR image obtained before PAE shows a large benign prostatic hyperplasia (straight arrow) and normal seminal vesicles (arrowheads). b Axial contrast-enhanced T1-weighted MR image obtained 1 month after PAE shows reduction of the prostate (straight arrows) and hypoperfusion in the seminal vesicles (arrowhead), suggestive of ischaemia. c DSA of the left prostatic artery (straight arrow) with same-side anterior oblique projection (35°) demonstrates contrast-medium staining in the left prostate lobe (asterisk). d CB-CT with axial view after catheterization of the left prostatic artery (straight arrow) demonstrates the small branches (curved arrow) supplying the seminal vesicles (the seminal vesicle artery) and contrast medium staining in the left prostate lobe (asterisk)
