Craniopagus parasiticus: A rare case.

Conjoined twins or Siamese twins are identical twins whose bodies are joined in the uterus. Craniopagus is a condition in which the heads of the two twins are joined. Craniopagus parasiticus is a rare condition in which one of the twins is rudimentary in form and parasitic on the other. Few cases of craniopagus parasiticus are reported in literature; here, we present one such rare occurrence.
