[Ultrasonic findings in polycystic ovary].
Nineteen patients with polycystic ovarian disease (PCO) underwent ultrasound examinations. Criteria of PCO were determined by clinical findings [(1) sterility (2) irregular menses], and hormonal analysis [(1) basal LH level greater than or equal to 20 mIU/ml, (2) LH/FSH greater than or equal to 2.5, (3) maximum LH level after LH-RH test greater than or equal to 150 mIU/ml]. Seven cases out of nineteen patients were confirmed by histologic examinations. Fourteen normal women were compared with PCO patients. We have obtained the following results. No significant differences between PCO groups and normal women were observed in uterine longest diameter (ULD) and uterine volume (UV). On the other hand, correlation tests of ovarian longest diameter (OLD), ovarian volume (OV), OLD/ULD and OV/UV were highly significant (p less than 0.01), as compared with each for normal women. The sonographic spectra of ovarian morphology in PCO were classified into three types. In type I, the ovary was filled with a light homogeneous echo. And type II was divided into two small types, IIa and IIb. In type IIa, small cysts (3-5 mm) were sporadic in the ovary and indistinct. In type IIb, the cyst was rather larger (5-7 mm) and more distinct than that of type IIa. In type III, the capsule echo of the ovary was thick and cysts under the capsule were 3-7 mm-sized and arranged regularly. We investigated the induced ovulation rates with clomiphene in each type. Two of 4 cases of type I and 6 of 8 cases of type IIa were induced.(ABSTRACT TRUNCATED AT 250 WORDS)
