Abstract
The incidence of conjoined twins as reported in a worldwide epidemiological study
is 1.47 per 100,000 births. It varies from 1 in 45,000–200,000 births. Conjoined twins
following assisted reproduction are even rarer and we report one such case. A 36-year-old
woman who conceived by intracytoplasmic sperm injection, was referred to the feto-maternal
unit for nuchal translucency scan. A diagnosis of thoracopagus conjoined twins was
made on ultrasound at 12 weeks 3 days of gestation. The couple was counseled in detail
and they opted for termination. Pregnancy was terminated medically and the ultrasound
diagnosis was confirmed. Assisted reproduction techniques involve a risk of conjoined
twins and the present case report supports this. Early diagnosis of conjoined twins
and determination of the type of fusion is possible. This aids in discussing the prognosis
and counseling the couple regarding options of termination or continuation of pregnancy.
