Abstract

Color and pulsed Doppler examinations can provide additional discriminative information on tumor vascularity, which can be evaluated along with morphology for more accurate diagnosis of uterine masses. Vascularization of the myoma is largely dependent on the hormonal status of the patient and the tumor size, position and extent of secondary degenerative changes. Large fibroids, especially those with degenerative and inflammatory changes, usually show increased diastolic flow and a lower resistance index (RI). The typical findings in most cases of uterine sarcomas are thin, randomly dispersed intratumoral vessels with very low impedance shunts. However, normal intratumoral vascularity can also be found in some cases of low-grade-type endometrial stromal sarcoma. Varying histological origin, cellular atypia and mitotic rate in uterine sarcomas can all significantly affect the intratumoral vascularity and blood flow characteristics detected by color Doppler. The results of previous studies suggest that using intratumoral RI alone for discrimination produces an overlap between uterine leiomyomas and uterine sarcomas. It seems that the complex evaluation of all parameters obtained by ultrasonography (morphology and size, vascular arrangement and intratumoral blood flow parameters) can help to extend the diagnostic efficiency.
