Craniopagus parasiticus

Craniopagus parasiticus (pronunciation: /kræniːoʊpægəs pærəsɪtɪkəs/) is a rare medical condition where a parasitic twin head with an undeveloped body is attached to the head of a developed twin. This condition is a type of conjoined twins where the twins are joined at the head.

Etymology

The term "Craniopagus" is derived from the Greek words "kranion" meaning skull and "pagus" meaning fixed. "Parasiticus" is derived from the Greek word "parasitos" meaning parasite. Thus, the term "Craniopagus parasiticus" refers to a parasitic twin fixed to the skull of the developed twin.
