Abstract:
Objective ToexploretheMRIfeaturesofthepseudoaneurysmsandarteriovenousmalformationsinuterus,andtoimprove ourunderstandingonthemforhigherdiagnosticaccuracy.Methods TheMRIfeaturesofthe4casesofuterinepseudoaneurysmsand the7casesofuterinearteriovenousmalformationswhichdiagnosedandcuredbyourhospitalwereanalyzedretrospetively.Results TheMRIofuterinepseudoaneurysms(n＝4)shownodular(n＝3)oroval(n＝1)abnormalsignalinthemyometriumsofuterus,low signalintensityonT1WI,highsignalintensityonT2WI.Thelesionenhancementissimilartotheuterinearterycommunicatingwiththe lesion.TheMRIofuterinearteriovenousmalformations(n＝7)showuterinepatchyabnormalsignal,andtheirboundaryarenotclear. Thereareanumberoftortuousbloodvessels.Thelesionsareobviouslyheterogenouslyenhanced,andthethickeneddrainagevessels couldalsobeseenoncontrastGenhancedimages.Thelesionsofuterinepseudoaneurysmsandarteriovenousmalformationsdon’tshow highsignalintensityonDWI,suggsetingnolimiteddiffusion.Conclusion The MRIcharacteristicsoftheuterinepseudoaneurysms showthattheuterinelesionenhancementissimilartotheuterinearterycommunicatingwiththelesion.The MRIcharacteristicsof theuterinearteriovenous malformationsarethatthereareanumberoftortuousbloodvesselsanddrainagevesselsintheuterus.
