ULTRASOUND ASSESSMENT MIDLINE STRUCTURES OF THE FETAL BRAIN IN THE SECOND TRIMESTER OF PREGNANCY: CORPUS CALLOSUM

Fetal brain was retrospectively evaluated in normal fetuses at 18-27 weeks of gestation, obtained by multiplanar echography. Most useful for assessment normal development of the corpus callosum measurement length of the corpus callosum. The multiplanar mode to obtain the mid-sagittal plane and measured length of the fetal corpus callosum from the most anterior aspect of the genu to the most posterior aspect of the splenium. Normal range plotted on the reference range (mean, 5 th and 95 th percentiles) of length of the corpus callosum, may be useful for assessment development of the corpus callosum in cases of suspicion on cerebral anomalies like hypoplasia, partial agenesis of the corpus callosum.
