Polycystic ovary syndrome: a new ultrasonographic and color Doppler pattern.

The aim of this study was to evaluate whether patients with partial bilateral polycystic ovaries show different ovarian and uterine blood flow to those with complete bilateral polycystic ovaries, and to investigate whether there is a correlation between ultrasonographic and hormonal parameters. Fifteen patients with partial polycystic ovaries and eighteen patients with complete bilateral polycystic ovaries underwent clinical, biochemical, gray-scale and color Doppler ultrasonographic evaluation. Hormonal (luteinizing hormone (LH), follicle-stimulating hormone (FSH), LH/FSH concentration ratio, estradiol, prolactin, androstenedione, testosterone), clinical (body mass index, Ferriman-Gallwey score), ultrasonographic (ovarian volume, number and distribution of subcapsular follicles, stromal score) and Doppler (uterine artery and intraparenchymal vessels pulsatility index, ovarian stromal vascularization) parameters were evaluated, in the early follicular phase (cycle day 3-5) in oligomenorrheic patients, or at random in amenorrheic patients. Significantly higher androstenedione plasma levels and LH/FSH concentration ratios were observed in complete bilateral polycystic ovaries. In partial polycystic ovaries, gray-scale and color Doppler ultrasonography showed different features in affected and unaffected areas of the ovary, similar to polycystic and normal ovary appearance respectively. In conclusion, PCOS does not predetermine a single ultrasonographic or Doppler pattern.
