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.
