title: Cephalothoracopagus syncephalus: a case report with previously unreported anatomical abnormalities and chromosomal analysis.
abstract: A case of cephalothoracopagus conjoined twins is presented. The abnormality was detected antenatally by the use of ultrasonography. A detailed anatomical description is given, including previously unreported abnormalities of the cerebrum and genito-urinary tract. Chromosomal analysis was also performed. This showed a pericentric inversion of one chromosome 9 in the fetus. Studies performed on the mother showed pericentric inversion of both chromosome 9s. A comparison of this case with previously reported cases in the literature is then given.
