Fetus in fetu is an extremely rare condition embryologically arising in monozygotic diamniotic twins with an incidence of 1:500,000 births. To the best of our knowledge, number of reported cases should not be more than 100 with majority of cases presenting in post natal life with only 5 cases detected prenatally. We are presenting a case diagnosed at 24 weeks of gestation on ultrasound with pre...

A 38 year-old woman presented with a dichorionic diamniotic twin pregnancy at gestational age of 32 weeks concerning for an abdominal wall mass in one of the twins. Initial ultrasound evaluation was suspicious for an omphalocele, but the affected twin was found to have bladder exstrophy at birth. This illustrates the difficulties of accurate prenatal diagnosis of bladder exstrophy in a twin pre...

We report on the prenatal diagnosis through array CGH of a dichorionic–diamniotic (DC/DA) twins discordant for Cri du Chat Syndrome. Structural anomalies on one of the twins lead to amniotic fluid sampling, which revealed a partial deletion on the short arm of the chromosome 5. Selective feticide of the affected twin was performed at 34 + 1 weeks' and elective Cesarean section at 37 + 2 weeks. ...

There is a long-held credo, as illustrated in Langman's Medical Embryology (11th ed., Sadler, 2010), that dichorionic diamniotic (DD) twins develop after embryo splitting in the early stages of embryonic development. However, from our clinical experiences of the examination of data from single-embryo transfers in 16 fertility clinics in Japan and from various reports, the majority of occurrence...

Methods A 30 year old woman with gravida 1, parity 0, abortus 0, admitted to our unit because of triplet pregnancy at 10th weeks of gestation. She underwent IVF treatment with transfer of one ‘day 3’ embryo resulting in a monochorionic-diamniotic triplet pregnancy. The three embryos appeared to share the same trophoblast, with two of them sharing the same amniotic sac. The two amniotic sacs wer...

Hypoplastic left heart syndrome is a congenital disease which accounts for 8% of all defects. Twin pregnancies have significantly higher risk structural than singleton ones, however the concordance rate has been found to be relatively low, even in monochorionic pregnancies. We describe here favorable evolution monochorionic, diamniotic, twin pregnancy both fetuses were diagnosed with hypoplasti...

Objectives: To determine the indications for referral, sonographic workload, diagnoses and outcomes of women with a multiple pregnancy referred to the New South Wales Fetal Therapy Centre (NSW FTC). Methods: Retrospective cohort study of twin and higher order multiple (HOM) pregnancies referred to the NSW FTC at the Royal Hospital for Women (RHW) Department of Maternal Fetal Medicine (MFM), Syd...
