Differentiation of uterine myoma and adenomyoma by transabdominal and transvaginal color Doppler ultrasound.

Objective To evaluate color Doppler flow imaging(CDFI) and two dimensional ultrasonography in the differential diagnosis of uterine myoma and adenomyoma.Methods Transabdominal and transvaginal color Doppler sonography was performed in 45 cases of uterine myomas and 38 cases of uterine adenomyoma to analyze the characteristics of two dimensional and color Doppler flow with them,50 normal women were chosen for control.Results The age of onset and clinical manifestations of two groups of patients were similar,but dysmenorrhea and uterine tenderness of uterine adenomyoma group were obvious.Characteristic changes were observed in the two dimensional ultrasonography of both the uterine myoma and adenomyoma.CDFI: RI of uterine artery of uterine myoma and uterine adenomyoma were lower than that of control group(P 0.05).In the group of uterine myoma,color blood flow was often detected in peripheral area of focal uterine lesions,bases of submucous and subserous myoma showed rich blood flow.The blood stream at edge of mass in patients with uterine adenomyoma was sparse or absence,and there was rich blood flow or starlike flicker color blood signal in the interior.The value of RI in the uterine adenomyoma's interior was higher than within and at the egde of the uterine myoma.Conclusion Transabdominal and transvaginal color Doppler ultrasonogrphy provide differential diagnosis of uterine myoma from uterine adenomyoma,the diagnostic accuracy of them must be improved with clinical performance.
