## Abstract Type II osteogenesis imperfecta (OI) is a perinatally lethal disorder due to type I collagen abnormalities that has been diagnosed successfully in the second trimester. We report a case of type II OI that was confirmed on postmortem histology and radiography presenting as increased nuch

โฆ Synopsis
Makrydimas and colleagues recently reported two cases of subcutaneous edema in the back of the fetal neck at 10-14 weeks associated with osteogenesis imperfecta [Makrydimas et al., 2001].
We report a very similar case we have observed at 13 and 16 weeks in a pregnancy without any family risk. A healthy primigravida 31-year-old Caucasian woman presented for first trimester screening at 13 weeks' gestation. Family history was unremarkable for skeletal dysplasias. An increased nuchal translucency was observed: the crown-rump length (CRL) was 72.3 mm and the nuchal translucency thickness was 3.8 mm (Fig. 1). The estimated risk for trisomy 21, calculated by a combination of maternal age and nuchal translucency thickness, was one in ten, so the parents

Before chorionic villus sampling at 10-13 weeks' gestation, 453 women had the crown-rump length and nuchal translucency (NT) measured with transabdominal ultrasound. There were 19 aneuploid pregnancies (ten cases of trisomy 21, six of trisomy 18, one of 47+marker, one 47,XXX, and one 45,X mosaic). A
We decided to assess the practicability of introducing nuchal translucency (NT) measurements as a screening programme for fetal Down's syndrome in the first trimester of pregnancy, within the population of women who receive ultrasound examinations in our department. Over a l-year period, measurement
