| Popis: | The goal of the gynecologist is to detect ovarian tumors in their earliest stages. Small virilizing tumors, which barely affect the size of the ovaries, are such lesions. Since the introduction of transvaginal sonography it is technically possible to detect small intraovarian neoplasms. Three cases of virilizing steroid cell tumors in postmenopausal women with ovarian volumes just exceeding the normal sizes for age are presented. High-frequency transvaginal ultrasound and color Doppler studies to measure flow parameters were used. These small tumors had different echogenicity from the surrounding ovarian tissue and two had low impedance-to-flow values. Gray-scale transvaginal sonography combined with color Doppler studies can make the diagnosis of small steroid cell tumors easier and, at times, better than other, more costly imaging modalities. |
