About


It is a condition that occurs in brain of the foetus when lateral ventricles become dilated. When the measurement is above 15 mm, ventriculomegaly is considered to be severe.


This condition can be diagnosed in around 1% of the pregnancies, i.e., 1-2 cases in 1000 pregnancies. (1)


- Not self-treatable
- Not self-diagnosable
- Lab tests or imaging are required


Causes


Generally, the cause of left ventriculomegaly is not identifiable. There can be several causes for left ventriculomegaly. Some of them are as follows:
- Loss of brain volume due to infection
- Impaired outflow of cerebrospinal fluid from the ventricles
- Damage and loss of brain tissue


Complications due to left ventriculomegaly:
- Hydrocephalus: It can cause ventricles to grow even more progressively.
- Benign macrocrania: It leads to increase in size of head.


Symptoms


A child suffering from hydrocephalus will show signs and symptoms once he is born. Some of the symptoms are as follows:
Self diagnosable:
- Abnormal growth in size of the head
- Inability of eyes to look upward
- Slow growth and delays in development
- Irritability
- Abnormal sleepiness
- Poor feeding and vomiting


Diagnosis


Diagnosis: This condition is diagnosed around 18-20 weeks of gestation period. There are two most commonly used tests:
- Ultrasounds: to examine the condition of blood vessels, organs, and tissues of baby in the womb.
- Amniocentesis: this test is used to detect chromosomal abnormalities in the baby.


Treatment


Medicines: there are certain treatments used to treat hydrocephalus such as shunt placement, endoscopic third ventriculostomy, and choroid plexus cauterization. Along with these treatments, the doctor will suggest a follow-up examination depending upon the condition.
