Real-Life Diagnostic Accuracy of MRI in Prenatal Diagnosis

Figure 2

Complete agenesis of corpus callosum. Gestational age: 27 weeks. (a) Sagittal SSFSE T2. (b) Coronal SSFSE T2. (c) Axial SSFSE T2. Complete agenesis of corpus callosum with right interhemispherical cyst with mass effect (solid black arrow) is shown. The right cerebral hemisphere is smaller in size, and malformation of cortical development is evident, with multiple anomalous sulci, bumpy cortical surface (solid black arrowhead), and cortical invaginations (empty white arrow). Regions of associated polymicrogyria (solid white arrowhead) and heterotopias bulging on the ventricle wall are depicted (solid white arrow). Fetal MRI provides useful information for perinatal management and prognosis over fetal ultrasound by detecting anomalies of the cerebral cortex and heterotopies not visible in the fetal ultrasound.
