Nonprogressive congenital unilateral ventriculomegaly

Congenital unilateral ventriculomegaly is a rare condition, usually caused by obstruction of the foramen of Monro. In the past, this condition required surgical intervention. We present a female newborn with nonprogressive unilateral ventriculomegaly which was initially detected by prenatal sonography. No surgical intervention was performed, and during the 9 months of follow-up, she had normal head growth and reached appropriate developmental milestones.
