Another diagnosis that can be suspected based on second-trimester ultrasound is agenesis of the corpus callosum (Figure 16), a condition in which the large midline bundle of white matter connecting neurons in the 2 hemispheres is absent. Sagittal imaging can identify hemivertebra (Figure 32). The vascular structure of the cerebral white matter in mid- to late gestation includes long, penetrating arteries that originate from the anterior, middle, and posterior cerebral arteries. Fetal anomalies can be diagnosed by ultrasound in early pregnancy, though second-trimester ultrasound can identify or exclude more conditions. The lips and palate are best evaluated with coronal imaging and transverse views at the level of the palate. One of the most commonly used grading systems for PVL on HUS describes four grades of severity: Grade 1 involves transient periventricular areas with increased echogenicity for 7 days or more; Grade 2 includes small, localized fronto-parietal cysts; Grade 3 presents with extensive periventricular cystic lesions; and Grade 4 involves areas of increased echogenicity in deep white matter which are evolving into extensive cystic lesions[26]. .
