313名妇女因临床怀疑有磨牙妊娠而接受盆腔超声检查，另外5例超声诊断但临床不怀疑为葡萄胎，其中50例最终证实为葡萄胎。有2例假阳性和2例假阴性超声解释。在50例证实有磨牙妊娠的患者中，超声计算出产前子宫体积，记录叶黄素囊肿的存在和大小。从超声测量宫内体积估计的胎龄与临床估计的子宫大小的相关性显示平均高估3.5周的胎龄倾向。10%的患者通过临床检查发现叶黄素囊肿，而37%的患者通过超声检查发现叶黄素囊肿。50例磨牙妊娠中有7例与磨牙后滋养细胞疾病有关。子宫体积较大或有叶黄素囊肿的患者在手术后发生侵袭性痣或绒毛膜癌的发生率不高。超声检查仍然是一种很好的诊断技术，但不能预测疏散后的临床过程。
From a group of 313 women referred for pelvic sonography because of clinical suspicion of molar gestation and 5 additional sonographically diagnosed but clinically nonsuspect cases of hydatidiform mole, 50 were ultimately proved to have a hydatidiform mole. There were 2 false-positive and 2 false-negative sonographic interpretations. In the 50 patients having a proved molar gestation, predelivery uterine volume was sonographically calculated, and the presence and size of theca lutein cysts was recorded. Correlation of gestational age estimated from sonographically measured intrauterine volume to clinical estimation of uterine size revealed a tendency to overestimate gestational size by a mean of 3.5 weeks. Theca lutein cysts were detected in 10% of patients by clinical examination, whereas they were detected by sonography in 37% of cases. Seven of 50 molar pregnancies were associated with post-molar trophoblastic disease. Patients with a volumetrically large-for-dates uterus or with theca lutein cysts did not have a higher incidence of postevacuation invasive mole or choriocarcinoma. Sonography remains an excellent diagnostic technique, but cannot predict the postevacuation clinical course.
