From: Beyond fetal magnetic resonance diagnosis of corpus callosum agenesis
A 29-year old pregnant female, 35th WG, (G3P2L2). MRI of the fetal brain in sagittal (a) and axial (b and c) views show: Herniation of brain parenchyma through a frontal midline defect measuring about 1.5 cm, associated with mild hypertolerism. Asymmetry of cerebral hemispheres, enlarged right cerebral hemisphere shows abnormal cortical infoldings and sulcation, large right posterior porencephalic cyst is communicating with deformed dilated right lateral ventricle body and the corpus callosum could not be identified, crowded posterior fossa with tonsillar herniation, and small skull size. Diagnosis: CCA, Chiari I with frontal cephalocele, right hemimegalencephaly, right porencephaly, Abnormal sulcal pattern, and microcephalic skull
