A Case of Heterotopic Pregnancy Diagnosed by Ultrasonogram / 대한산부인과학회잡지

Heterotopic pregnancy is a condition in which ectopic and intrauterine pregnancies coexist. The reported incidence varies widely from 1 in 1000 to 1 in 30000 pregnancies. Assisted reproductive technologies have led to an increase in the number of heterotopic pregnancies. Because heterotopic pregnancy is difficult to diagnose early and it has high morbidity and mortality rate, careful pelvic examination combined with transvaginal sonogram and serial beta-HCG determinations are important. We experienced a case of heterotopic pregnancy in a natural cycle diagnosed by ultrasonogram who continued intrauterine pregnancy successfully.

A Case of Ectopic Breast Tissue in the Vulva / 대한산부인과학회잡지

Ectopic breast tissue may be seen along a diagonal line drawn from axilla to groin and it is rare with only a few reports in the world. There is a relatively frequent occurrence of ectopic breast tissue close to the breast or in the axilla, but the vulvar location is rare. We experienced a case of ectopic breast tissue in the vulva and reported it with brief review of literatures.

A Case of Osteogenesis Imperfecta: Diagnosis in Uterus by Ultrasonogram / 대한산부인과학회잡지

Osteogenesis imperfecta is a heterogeneous group of disorders that are characterized by connective tissue defects resulting in bone fragility, blue sclera, impaired hearing, defective dentition, and hyperlaxibility of the joints. The overall incidence of osteogenesis imperfecta is estimated at 1/25,000. We recently experienced a case of osteogenesis imperfecta type II diagnosed in uterus by ultrasonogram and confirmed after termination of pregnancy and autopsy. We report a case here with a brief review of the literature.

A Case of Struma Ovarii / 대한산부인과학회잡지

Struma ovarii is a monodermal and highly specialized teratoma which is composed predominantly or entirely of thyroid tissue. It is rare tumor accounting for 2.7% of ovarian mature cystic teratoma. Most of the tumors are benign. Malignant change has been reported in approximately 5% of cases. We have experienced a case of struma ovarii with brief review of the literature.

Three Cases of Spina Bifida by Antenatal Ultrasonogram / 대한산부인과학회잡지

The prenatal diagnosis of spina bifida includes the combined use of maternal serum alpha-fetoprotein (MSAFP) screening and fetal sonography. On ultrasonogram, spina bifida is characterizd by visualization of the spinal defect and associated cranial abnomalities: the Lemon sign, the Banana sign, ventriculomegaly, small biparietal diameter, and obliteration of the cisterna magna. We should now be able to rely on ultrasound as the main technique for diagnosis of spina bifida when MSAFP is elevated. Recently, we have experienced three cases of spina bifida diagnosed with meningomyelocele, lemon sign, banana sign and ventriculomegaly on ultrasonogram at respectively 18+3, 18, and 18+6 weeks of gestation. We present these cases with a brief review of literatures.
