case_images: Brain sonography. (A) Right sagittal view, (B) left sagittal view, and (C,D) the coronal plane, showing ventriculomegaly, especially at the right side (A).

case_images: Brain sonography on the first day revealed bilateral ventriculomegaly, particularly on the right side, with midline deviation to the left side (Figure 1). Developmental milestones were achieved by the age of 7 months (Supplementary Figure S1).
case_images: Preoperative T2 fluid-attenuated inversion recovery (FLAIR) sequence in the transverse view (A) showing bilateral ventriculomegaly and contralateral shift of the septum pellucidum (arrow), and postoperative T2 FLAIR sequence transverse view (B) showing regressive change of right-sided ventriculomegaly.

case_images: The MRI also revealed a left shift of the septum pellucidum (Figure 2A) and normal-sized third and fourth ventricles, which suggested a complete obstruction of the right and partial obstruction of the left of the FOM. Follow-up brain MRI performed 3 months after the operation showed significant regression of bilateral ventriculomegaly (Figure 2B).
case_images: Intraoperative image showing obstructed foramen of monro, which was fenestrated to connect the bilateral ventricles.

case_images: The obstructed right FOM was identified by tracing the choroid plexus, and fenestration of the membranous obstruction of the FOM was conducted with membrane perforator and Fogarty catheter (Figure 3).
