Abstract
A twin pregnancy with one hydrocephalic fetus with oligohydramnios is presented. Sonographic evaluation could not exclude monochorionicity. Before considering selective feticide, blood samples from both fetuses were examined for DNA 'fingerprint' analysis. The different banding p atterns of the blood samples established dizygosity. This procedure is suggested in cases where sonography fails to determine chorionicity.
