Welcome to ehealthforum.
The Venriculomegaly due to aqueductal stenosis is found in about 1 in 2000 pregnancies (more common in male babies). The major causes for such anomalies are related to infections during pregnancy like cymegalovirus, toxoplasma, syphilis, and rubella. A work-up to look for evidence of these infections might be necessary. The babies with mild isolated ventriculomegaly of less than 12 mm have excellent prognosis. The treatment for hydrocephalus depends on the type of fetal hydrocephalus, the rate of progression, gestational age and, ultimately, the family's wishes. In conventional treatment the fetus is followed with serial ultrasound scans. If the ventriculomegaly is stable, the fetus is carried to term. The decision of performing cesarean section on the discretion of the obstetrician based on head size at term along with immediate shunt insertion. This should be done in a clinical center with extensive experience in neonatal surgery.
Getting a karyotyping done on parents is also advised to see if it is a congenital X-linked hydrocephalus. The presence of sonographic findings of other intracranial and spinal abnormalities suggests X-linked hydrocephalus.
The recurrence rate in subsequent pregnancies is about 4%.
The complete and detailed prognosis of the long term effects and survival of the baby should be discussed with a perinatologist based on the sonographic findings and serial follow-up scans to decide whether to carry on with pregnancy or not. Few families decide for abortion if the quality of life of baby after birth is said to be severely affected in the prognosis. However, most babies with isolated ventriculomegaly have normal outcomes, with only about 20% of babies having some degree of developmental delay.

Hope this helps. Take care.
