Imaging of bilateral prostatic artery embolism. a Both the right prostate artery (black solid arrow) and the dorsal penis artery (white arrow) originate from the internal pudendal artery (black dashed arrow). There are communicating branches between the right dorsal penis artery and the left dorsal penis artery. The left dorsal penis artery can be seen, suggesting that the right dorsal penis artery is the dominant blood supply. b After embolization of the right prostate artery, neither the prostate artery nor the dorsal penis artery were obstructed. c The left prostate artery (black solid arrow) and dorsal penis artery (white arrow) were separated. d After embolization, the left prostate artery was not developed, and the left dorsal penis artery was developed
