由于我们的轶事经验表明，早期葡萄胎妊娠超声检查中经典描述的“暴风雪”外观通常不存在，而且卵泡膜叶黄素囊肿也很少见，因此我们检查了早期完全性葡萄胎妊娠的超声检查外观。我们回顾了 21 例经组织学诊断的完全性葡萄胎妊娠的超声检查报告和临床数据，超声检查平均孕龄为 10.5 周（范围为 4 至 18 周）。超声检查诊断葡萄胎妊娠 12 例（57%），鉴别诊断中排第二位的为 1 例（4.8%），8 例（38%）未考虑。未发现卵泡膜黄素囊肿。 13 周或以上的 5 例葡萄胎妊娠中，有 5 例 (100%) 被前瞻性诊断，而 16 例早期妊娠中，只有 8 例 (50%) 被前瞻性诊断。在对 16 名患者的可用图像进行回顾性审查时，16 幅图像中只有 9 幅 (56%) 表现出经典外观，并且没有看到卵泡膜黄素囊肿。我们得出的结论是，超声检查中完整痣的典型表现在不到三分之二的病例中可见，在妊娠早期则更少见。卵泡膜黄素囊肿的患病率非常低。
Since our anecdotal experience indicates that the classically described "snowstorm" appearance on ultrasonography of early molar pregnancies is often not present and that theca‐lutein cysts are also rare, we examined the ultrasonographic appearance of early complete molar pregnancies. We reviewed the ultrasonographic reports and clinical data of 21 cases of histologically diagnosed complete molar pregnancies with a mean gestational age at sonography of 10.5 weeks (range, 4 to 18 weeks). The diagnosis of molar pregnancy was made on ultrasonography in 12 (57%) cases, was second in the differential diagnosis of one (4.8%) case, and was not considered in eight (38%) cases. No theca‐lutein cysts were identified. Five of five (100%) molar pregnancies of 13 weeks or over were diagnosed prospectively, while only eight of 16 (50%) earlier pregnancies were correctly diagnosed prospectively. In a retrospective review of the available images of 16 patients, only nine of 16 (56%) images demonstrated the classic appearance, and no theca‐lutein cysts were seen. We conclude that the classic appearance of complete moles on ultrasonography is seen in less than two thirds of cases and even less commonly in the first trimester. The prevalence of theca‐lutein cysts is very low.
