目的：探讨卵巢异位妊娠的超声表现。方法：对所有确诊为卵巢异位妊娠的妇女的超声报告、录像带、病历和手术总结进行回顾性分析。检查由放射科-产科医生或产科-母胎医学专家亲自进行。结果：在13年的研究期间发现了6例。月经年龄从6周到9周半不等。大多数（5/6）患者出现腹痛，其中3例在妊娠前或妊娠7周出现腹痛。6例患者中5例可见宽回声环伴内部回声区；其中一个还含有卵黄囊，另一个可以看到胎心运动。5例患者回声环均出现在卵巢表面或卵巢实质内。5例发现卵巢环的回声强度大于卵巢环的回声强度。手术时，6例卵巢妊娠患者均出现出血性卵巢囊肿。未见回声环的患者为妊娠破裂。6例均经活检证实。结论：卵巢妊娠多表现为卵巢表面或卵巢内囊肿，外环回声较宽。卵黄囊或卵黄胚则不太常见。内容物的外观与胎龄相比滞后。早期腹痛很常见。(C) 2005年由美国妇产科医师学会出版。
OBJECTIVE: To evaluate the ultrasonographic findings of ovarian ectopic pregnancies.METHODS: The ultrasonographic reports, videotapes, medical records, and operative summaries were reviewed for all women with a confirmed diagnosis of an ovarian ectopic pregnancy. Examinations were personally conducted by a physician who was either a radiologist-obstetrician or an obstetrician-maternal-fetal medicine specialist.RESULTS: Six cases were identified in the 13-year period studied. Menstrual ages ranged from 6 to 9 2/7 weeks. Most (5/6) patients had abdominal pain, with 3 demonstrating it before or at 7 weeks gestation. A wide echogenic ring with an internal echolucent area was seen in 5 of 6 patients; 1 of these also contained a yolk sac, and in another, fetal heart motion could be seen. The echogenic ring seemed to be on the surface of the ovary or within the substance of the ovary in all 5 patients. The echogenicity of the ring was greater than that of the ovary in the 5 patients in whom it was identified. At surgery, the ovarian pregnancies had the appearance of a hemorrhagic ovarian cyst in all 6 patients. In the patient in whom no echogenic ring was seen the pregnancy had ruptured. All 6 cases were biopsy proven.CONCLUSION: Ovarian pregnancies usually appeared on or within the ovary as a cyst with a wide echogenic outside ring. A yolk sac or embryo was less commonly seen. The appearance of the contents lagged in comparison with the gestational age. Early abdominal pain was common. (C) 2005 by The American College of Obstetricians and Gynecologists.
