congenital varicella syndrome encompasses a broad spectrum of malformations present in children of mothers who developed chickenpox during the fi rst 20 weeks of gestation. we report a case of a monochorionic diamniotic twin pregnancy, with maternal exposure to chickenpox during the thirteenth week of gestation, which produced one symptomatic and one healthy child.

Fetus in fetu (FIF) is an extremely rare cause of infantile abdominal mass where a rudimentary, malformed monozygotic-diamniotic twin grows inside the other twin. We describe a male infant with double or twin fetuses in fetu. The diagnosis was made on a computerized tomography (CT) scan of the abdomen and confirmed on surgery. Surgical excision was done and the baby did well post operatively.

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...

Fetus-n-fetu is a fascinating diagnosis explaining the development of ‘baby within a baby’. It results out of a monozygotic diamniotic twin pregnancy in which a twin is absorbed into the body of its sibling. The surviving twin often presents with abdominal mass and the diagnosis is only confirmed by surgical exploration. It is often mimics retroperitoneal teratoma on imaging and poses a challen...

We report on two cases of prehospital initiated precipitated preterm deliveries with breech presentation, which were completed at the hospital. Case 1 involved a precipitated breech delivery in a multipara, and case 2 an unrecognizeddizygotic (diamniotic, dichorionic) twin pregnancy, with precipitated preterm breech delivery of the first twin, in a multipara.

Fetus- in- fetu (FIF), is a rare congenital anomaly that occurs due to malformed fetus growing inside the twin. It occurs due to the aberration in the diamniotic monochorionic monozygotic twinning with unequal division of inner cell mass of blastocyst leading to inclusion of small cell mass inside the developing sister fetus. The most common presentation will be with intra-abdominal mass locat...

OBJECTIVE To construct monochorionic diamniotic (MCDA) and dichorionic diamniotic (DCDA) twin reference ranges for umbilical artery (UA) pulsatility index (PI), UA resistance index (RI), fetal middle cerebral artery (MCA) PI and peak systolic velocity (PSV) and cerebroplacental ratio (CPR) from 24 weeks' to 38 weeks' gestation and compare these with published normal values for singleton pregnan...

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...

Arteriovenous fistulas of the placenta are extremely rare in singleton pregnancies and, to our knowledge, have not previously been reported in twin gestations. We describe a case of an arteriovenous fistula of the placenta in a diamniotic-monochorionic twin pregnancy complicated by twin-to-twin transfusion syndrome (TTTS). The arteriovenous fistula was demonstrated by color-coded vascular injec...
