Figure 1
Prenatal ultrasound images at 25 weeks of gestation demonstrate a dilatation of the cisterna magna >10 mm (arrows) and nodular lining of walls of the lateral ventricles (oval).
Figure 2
Sagittal and axial T2w images (a, b) and axial T1w image (c) of the brain performed at a gestational age of 25 3/7 weeks. The ventricular lining (closed arrows and ovals) shows a bilateral nodular thickening following the signal intensities of the grey matter (open arrows).
Figure 3
Post-mortem axial and sagittal T2w (a, b) and axial T1w (c) MR images of the brain at a fetal age of 27 weeks. The ventricles are lined with multiple nodules (closed arrows and ovals) following the signal intensities of the grey matter (open arrows).
