Ultrasound in utero from IV-6 (A). Image showed ventricular asymmetry and brain MRI confirmed right frontotemporal dilatation (B). IV-5-Brain MRI revealing porencephalic cyst of frontal horn of lateral right ventricle (C). (D) III- 3-Brain MRI showed small asymptomatic lesions in white matter. No microbleeds or cystic cavities were found. (E,F) IV-3-Brain MRI showed left frontotemporal dilatation and diffusion tensor imaging (DTI) sequences demonstrated no left corticospinal tract (cranio-caudal fibers, indigo, with arrows). A dashed arrow indicates secondary atrophy in the left cerebral peduncle.

He underwent at birth neurosonography for axial hypotonia that revealed ventricular asymmetry and right frontotemporal dilatation (Figure 3). IV-6 disclosed a large right-sided frontoparietal cavity (Figure 3B) with communication to the lateral ventricle, isosignal to CFS. IV-3 had a left hemisphere porencephalic cyst and the lack of evidence of a left corticospinal tract on tractography (Figures 3E,F), IV-5 had a porencephalic cyst on the right lateral ventricle (Figure 3C), and III-3 had leukoencephalopathy (Figure 3D).
