Ovarian cysts were diagnosed by antenatal ultrasonographic examination in 15 fetuses between 19 and 37 weeks' gestation. In six cases there was ultrasonographic evidence of torsion. Intracystic flocculation, which typically was deposited on the sloping part of the cyst, gave a characteristic liquid interface that was regarded as ultrasonographic evidence of torsion. All cases with evidence of torsion were managed surgically post partum, and in all patients this complication was confirmed. The remaining nine cases were followed up by repeated ultrasonograms, and in all patients disappearance of the cyst was documented within the first 6 months of life. The mean size of cysts with evidence of torsion was 5.41 +/- 0.25 cm, and the mean size of those without torsion was 4.33 +/- 0.3 cm (p less than 0.01). Histologic examination of the surgical specimen in the cases with evidence of torsion revealed follicular cysts in three cases and necrotic ovarian cysts with no specific epithelial findings in the remaining three. We recommend continuous ultrasonographic assessment of antenatally diagnosed cysts and believe that the choice of treatment depends on the appearance of the cyst and its evolution throughout pregnancy.
在15例妊娠19至37周的胎儿中，通过产前超声检查诊断出卵巢囊肿。6例有超声扭转证据。囊内絮状物通常沉积在囊肿的倾斜部分，形成特征性的液界面，被视为扭转的超声证据。所有有扭转证据的病例均在产后进行手术治疗，且所有患者的这一并发症均得到证实。其余9例通过重复超声检查进行随访，所有患者均记录到囊肿在出生后6个月内消失。有扭转证据的囊肿平均大小为5.41±0.25厘米，无扭转的囊肿平均大小为4.33±0.3厘米（p<0.01）。有扭转证据的病例手术标本的组织学检查显示，3例为滤泡囊肿，其余3例为坏死性卵巢囊肿，无特异性上皮表现。我们建议对产前诊断的囊肿进行持续超声评估，并认为治疗方法的选择取决于囊肿的外观及其在整个孕期的演变。
