What is Ventriculomegaly?

Q:
What is ventriculomegaly?

A:
Ventriculomegaly is a brain condition that occurs in the fetus when the lateral ventricles become dilated. Commonly, if the width of the atrium of the lateral ventricle is greater than 10 mm, it’s ventriculomegaly.

Symptoms:

Infants with mild ventriculomegaly typically have no symptoms, while those who suffer from progressive ventriculomegaly tend to show symptoms of hydrocephalus, including:

  • Abnormally rapid head growth
  • Abnormally full fontanel
  • Distended scalp veins
  • Eyes that cannot look upward or appear to be staring downward (sunset sign)
  • Developmental delays
  • Irritability or abnormal sleepiness
  • Poor feeding
  • Vomiting

What causes Ventriculomegaly?

No single cause has been confirmed to result in Ventriculomegaly. However, four factors may enlarge the ventricles:

  • Hydrocephalus
  • A minor self-limiting imbalance in fluid circulation and absorption that becomes compensated
  • Defects in brain development
  • Damage or loss of brain tissue

Outlook:

Most babies who have mild, nonprogressive ventriculomegaly without other brain damage won’t be affected at all. They will have a totally normal and healthy development.
