Objective:
We report a case of conjoined twins in a trichorionic quadruplet pregnancy after ovulation induction with clomiphene citrate for anovulation.
Methods:
The diagnosis of a trichorionic quadruplet pregnancy was made in routine ultrasound at 11 weeks' gestation.
Results:
Conjoined twinning was thoracopagus and presented with increased nuchal translucency. Selective termination of the conjoined twins was performed with potassium chloride injection. The patient delivered 2 healthy infants after an uneventful follow-up.
Conclusion:
Monozygotic twinning has increased with widespread usage of ovulation induction agents and assisted reproductive techniques. Early detection of conjoined twinning and chorionicity is essential for an optimal obstetric management and outcome.
