Dear Doctor, I d to ask you about ventricle enlarged issue of my son. He s nearly 10 months old, can roll but still not seat by his own until now. I m very worry about his status. He was good when my wife in pregnant and when he was born. We just found the ventricle enlargement issue last 3 months ago when we feel he might got some thing wrong cause he ussualy get fever, weak and late in seat and his head circumference also was at high side (90 percentile). I m providing you the ultrasound scan as below and wonder if I can do anything to get my son better. - At 7 month, his lateral ventricle: 12.7mm (left), 13.7mm (right) and third ventricle: 11mm. Third ventricle is not enlarged. - At 9 month, his lateral ventricle is enlarged up to 15.6mm and 10.4mm for third ventricle, forth ventricle is not enlarged. - At 9.5 month, his lateral ventricle enlarged up to 16mm and third ventricle: 12.8mm. Thank you indeed for your review and support Regards.
