Diprosopus: A Rare Conjoined Twin

Abstract

Diprosopus twin is a rare form of conjoined twin with incidence of one case in 180000 to 15 million births. This is a rare congenital anomaly whereby face is duplicated on the head. Usually, this type of fetuses are stillborn. A 24 years unregistered primigravida presented to our hospital at 26 weeks of gestation. On clinical examination and after ultrasonography, anencephaly and polyhydramnios was diagnosed. Labor was induced considering nonviable fetus due to anencephaly. The born fetus was female baby weighing 2.2 kg. It was a fresh stillborn with external features showing two faces, two sets of eyeballs, two sets of ears with medial ears fused, two noses and two mouths with single body. Fetus had anencephaly with proptosed eyeball. So far, very few cases are reported.
