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


METHODS
Case report.


METHODS
Perinatal center at a Japanese university hospital.


METHODS
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.


METHODS
A female infant was delivered by scheduled cesarean section at 30 weeks of gestation. The cesarean section was performed for dystocia.


METHODS
Brief review of parasitic twin and malformations in fetuses achieved after ICSI.


RESULTS
Resuscitation was not done because of the poor prognosis for both fetuses. Molecular analysis with informative genetic markers is consistent with monozygotic pregnancy.


CONCLUSIONS
A careful ultrasound examination is indicated to detect additional anomalous findings in twin fetuses achieved after ICSI.
