Placental polyp with prominent neovascularization Akihiro Takeda, M.D., Kazuyuki Koyama, M.D., Sanae Imoto, M.D., Masahiko Mori, M.D., Kotaro Sakai, M.D., Hiromi Nakamura, M.D.  Fertility and Sterility  Volume 93, Issue 4, Pages 1324-1326 (March 2010) DOI: 10.1016/j.fertnstert.2009.03.065 Copyright © 2010 American Society for Reproductive Medicine Terms and Conditions

Figure 1 Image diagnostic findings of placental polyp with prominent neovascularization after elective abortion. (A) Transvaginal ultrasonography showing heterogeneous polypoid mass (arrow) within the uterine cavity. (B) Color Doppler ultrasonography showing prominent vascular flow within polypoid mass. (C) Coronal and (D) sagittal 64-row multidetector computerized tomographic angiographic images showing prominent vascular mass (arrow). Major feeding artery was identified as the left uterine artery (arrowhead). (E) Selective left uterine arterial angiogram demonstrating prominent vascular mass (arrow) with blood flow supplied from the left uterine artery (arrowhead). (F) Color Doppler ultrasonography showing disappearance of vascular flow (arrow) in the placental polyp tissue a day after selective uterine artery embolization.
