Objective ToimprovetherecognitionofovariancysticlesionsbyanalyzingCTand MRIappearances.Methods A retrospectivereviewofCTand MRIimagesof67caseswithpathologicallyprovenofovariancysticlesionswasperformed.Among which,58casescarriedoutplainCTscan,52casesunderwentenhancedCTscan,12casesunderwentplainMRIscan,and7casesunderwent enhancedMRIscan.Results 20caseswereovariancystadenomas,14caseswerecystadenocarcinomas,8caseswereteratomas(1case wasmalignant),5caseswerestrumaovarii,15caseswerecysts,3casesweremetastases,and2caseswereovariantuberculosis.The CTand MRIcharacteristicsofthecysticlesions,inculdingsize,shape,thicknessofcystwall,wallnodule,densityorsignalintensity andenhancementfeatureswerevaluableindifferentialdiagnosisofovariancysticlesions.Conclusion CTand MRIappearancesofovarian cysticlesionshavesomecharacteristics,includingcysticwallandseptaofcystadenocarcinomasirregularthickened,papillaryprotuberance andascites.Teratomasoftencontainfatandcalcification.Strumaovariipresentsmultilocularcystic-solidmass,withthesolidportions markedenhancement.Metastatictumorshaveahistoryofprimarygastrointestinalneoplasmsandperitonealeffusion.
