An omphalopagus parasitic twin after intracytoplasmic sperm injection.

OBJECTIVE

To describe a first case of parasitic twin achieved after intracytoplasmic sperm injection (ICSI).

DESIGN

Case report.

SETTING

Perinatal center at a Japanese university hospital.

PATIENT(S): A 30-year-old pregnant Japanese woman with a history of secondary infertility achieved after ICSI was diagnosed with an omphalopagus parasitic twin pregnancy by prenatal ultrasound at 28 weeks of gestation.

INTERVENTION(S): A female infant was delivered by scheduled cesarean section at 30 weeks of gestation. The cesarean section was performed for dystocia.

MAIN OUTCOME MEASURE(S): Brief review of parasitic twin and malformations in fetuses achieved after ICSI.

RESULT(S): Resuscitation was not done because of the poor prognosis for both fetuses. Molecular analysis with informative genetic markers is consistent with monozygotic pregnancy.

CONCLUSION(S): A careful ultrasound examination is indicated to detect additional anomalous findings in twin fetuses achieved after ICSI.
