A case of thoraco-omphalopagus with omphalocele with 3D ultrasonography and MRI / 대한산부인과학회지

One of the most interesting congenital malformations is a conjoined twin. Conjoined twins are a rare occurrence in obstetric practice. More commonly known as Siamese twins, this phenomenon is shrouded in mystery and considered a curiosity by general public. Current technology is providing a basis for earlier diagnosis and a better prognosis. Frequently, the twins are born dead, but there are a few cases in which the twins survive. We present a case of thoraco-omphalophagus with omphalocele in 35 years old woman at 25weeks 5 days gestation by 3-D ultrasonography and MRI.

A case of abdominal pregnancy implanted on uterosacral ligament / 대한산부인과학회지

Abdominal pregnancy, a rare type of ectopic pregnancy is difficult to be suspected at its first presentation. The diagnosis of this rare disease may often be delayed, since early symptoms are usually non-specific. In some cases, delayed diagnosis of abdominal preganacy can be associated with catastrophic hemorrhage secondary to placental separation. A 24-year old woman visited our emergency unit, presenting with a sudden-onset low abdominal pain. She had undergone uterine curettage 3 weeks before. Transvaginal sonogram of the cul-de-sac revealed complex fluid consistent with blood. On diagnostic laparoscopic operation, we found a ruptured cystic, conception-like structure near the right uterosacral ligament. Histology of the resected structure finally showed chorionic villi consistent with abdominal pregnancy. In this report, we present an unusual case of abdominal pregnancy. This case underscores the careful ultrasonic determination of gestational location at early pregnancy.

An Unexplained case of Recurrent Massive Subchorionic Hematoma in Midpregnancy / 대한산부인과학회지

Placental abnormality is the important predisposing cause of intrauterine growth retardation. Massive subchorionic hematoma is defined as a large size of maternal blood clot that separates the chorionic plate from the villous chorion and can result in serious obstetrical complications. We report a case of massive subchorionic hematoma diagnosed prenatally, and propose an additional peculiar finding detectable on both the ultrasound and magnetic resonance images: a large hematoma in the subchorionic region at 17 weeks gestation. At 18 weeks 2 days gestation, the fetus was miscarried. The clinical and pathological findings were compatible with massive subchorionic hematoma. Recurrent massive subchorionic hematoma without thrombophilic finding was observed at the next pregnancy in 17 weeks 5 days by ultrasound. The patient was managed conservatively and had successful outcome at term. So we report the case with the brief review of literatures.
