Color Doppler sonography of endometrial masses.

Objective: To correlate the color Doppler sonographic features of endometrial masses with histologic characteristics and microvessel density.

Methods: We performed a retrospective analysis of 10 postmenopausal and 5 premenopausal women with abnormal bleeding who had color Doppler sonography and histologic studies of endometrial masses.

Results: Endometrial masses that contained multiple branches on color Doppler sonography were more likely carcinomas, even though both polyps and carcinomas were vascular on color Doppler sonography and their microvessel densities were similar. On color Doppler sonography, polyps averaged 1.2 detectable vessels versus 3.4 for carcinomas.

Conclusions: Color Doppler sonography may be useful in distinguishing carcinomas from polyps in women with thickened endometria.
