A term of art for the über rare (1-5/105 pregnancies) coexistence of a normal intrauterine pregnancy (usually a single, non-twin fetus) and gestational trophoblastic disease–GTD, one or moles together, which typically occurs in a background of infertility treatment and in vitro fertilisation.

Synonym Twin pregnancy
