Conjoined twins: a rare case of thoraco-omphalopagus.

Conjoined twins are a rare entity. Only few cases have been reported in the medical literature. They are a rare and exclusive type of monozygotic twins. They are caused by a faulty division of the embryonic disk. Due to high post-natal morbidity and mortality, an early pre-natal diagnosis is a must. All the monozygotic twins should be carefully screened for conjoinnment and if it is present, the type and the degree of sharing of the foetal organs should be delineated. There are many associated anomalies, of which congenital heart defects are the major prognostic factors. Here, we are reporting a case of thoraco-omphalopagus in which there was sharing of the foetal heart, liver and the intestinal loops.
