While studies looking at outcomes of this condition have identified high rates of genetic and structural abnormalities, it is not clear that the prognosis is poorer compared to fetuses with comparable NT measurements not categorized as cystic hygroma.2. The most common abnormalities observed for the first time in the ultrasounds at 35 to 37 weeks were: Incidence of abnormalities seen at 35 to 37 weeks was 0.5% and those that were detected exclusively for the first time at the examination were ovarian cyst, microcephaly, achondroplasia, dacryocystocele, and hematocolpus. Although ultrasounds require no radiation, only a trained professional who can accurately interpret the results should perform them. The Papile grading system [24], first described in 1978 using CT scan images, has been adapted for other imaging modalities (notably HUS and MRI), and is still the most commonly used IVH grading system in Canadian centres.

According to ACOG, this ultrasound measures the space at the back of a fetus' neck. Events leading to cerebral blood flow instability (e.g., respiratory distress with acidosis, hypo- or hypercarbia, or rapid changes in blood pressure due to cardiorespiratory instability) in the early postnatal course have also been associated with GMH-IVH. These might include chorionic villus sampling (CVS) or amniocentesis, which screen the baby for congenital disorders. Losing the mucus plug is another sign that labor is very close. Abnormal tone, such as fixed extension of the legs or clenching of the fingers Figure 37), can indicate a neurologic, neuromuscular, or musculoskeletal abnormality. Except for emergencies, CT scans are now generally avoided for newborn imaging. Although hemorrhagic and ischemic injuries are caused by different pathophysiological processes, they often occur together. The Papile system does not specifically include white matter lesions in brain locations other than periventricular areas, or lesions inthe cerebellum, basal ganglia, and brainstem. While open neural tube defects are usually multifactorial in origin, they may be a feature of Trisomy 18. Sagittal imaging can identify hemivertebra (Figure 32).

At 12 weeks acrania is suspected by absence of the normally ossified skull and distortion of the brain (exencephaly). In infants with moderate-to-severe anomalies on HUS, or when risk for WMI is greater, a term-corrected MRI may be considered, always weighing in cost, need to transport, the infants clinical stability, and the clinical purpose of imaging (e.g., whether it will influence access to specialized medical care). Stored three-dimensional (3D) ultrasound volumes of the fetal head at 11-13 weeks' gestation from 407 euploid and 88 chromosomally abnormal fetuses (Trisomy 21, n = 40; Trisomy 18, n = 19; Trisomy 13, n .
