Cephalothoracopagus: A rare conjoined twins, pre and postnatal findings.

Being unique is good, but not so for conjoined twins. Cephalothoracopagus is a rare type of conjoined twins, which is a rare monozygotic twinning resulting in imperfect fusion of the head, chest and upper abdomen. These twins have separated limbs and pelvis. The incidence of conjoined twins is 1 per 50,000 to 1 per 200,000 births. The cephalothoracopagus however is very rare variant seen in 1 in 3 million births. In literature approximately 200 cases have been reported till now. The cephalothoracopagus janiceps has two types: disymmetros and asymmetros. We present a case of cephalothoracopagus janiceps disymmetros in a 22-year-old gravida at 19 weeks gestation.
