What are the effects of ventriculomegaly?

If the ventriculomegaly progresses, the baby may have symptoms of hydrocephalus, including: an unusually large head. a rapid increase in head size. extreme sleepiness.

Should I be worried if my unborn baby’s brain ventricles are larger than they should be?

If the ventricles are more than 15 mm wide, the enlargement is considered severe. Fetal ventriculomegaly occurs in approximately one in every 1,000 births, and in roughly half of the cases, there are no other findings or abnormalities in the baby.

What infections can cause ventriculomegaly?

These are:

• Cytomegalovirus—an infection caused by a type of herpes virus.
• Toxoplasmosis—an infection linked to cat stool or infected food.
• Syphilis—a sexually transmitted infection (STI)
• Chickenpox.
• Lymphocytic choriomeningitis—a virus spread by mice (rare)

Is ventriculomegaly associated with Down syndrome?

Ventriculomegaly is defined as a width of 10 mm or greater of the lateral ventricles at the level of the atria (Fig. 151.4). It is associated with an increased risk of aneuploidy, including Down syndrome. In a large series of 2743 cases, 3.8% of fetuses had aneuploidy, and 2% of all cases had Down syndrome.

Can ventriculomegaly cause autism?

Similarly, studies have shown that prenatal isolated ventriculomegaly is associated with later developmental delay (e.g., in fine motor and expressive language skills (Lyall et al., 2012)) and psychiatric diagnoses (autism and schizophrenia) (Gilmore et al., 1998; Gilmore et al., 2001; Palmen et al., 2005).

What causes mild ventriculomegaly in fetus?

Approximately 5% of cases of mild to moderate ventriculomegaly are reported to result from congenital fetal infections, including cytomegalovirus (CMV), toxoplasmosis, and Zika virus.

Can Covid cause ventriculomegaly?

Case report: Two cases of severe ventriculomegaly, neurological dysfunction, and seizures were found in neonates with prenatal exposure to COVID-19 infection during the first and third trimesters of pregnancy.

Is ventriculomegaly hereditary?

Approximately 90% of cases with 17q12 duplication syndrome are inherited from parents with normal or slightly abnormal phenotypes. Parents without the phenotype cannot be sure whether the fetus is abnormal.

What causes enlarged ventricles in the brain in fetus?

Ventriculomegaly develops early in pregnancy. Two of the main factors that cause enlarged ventricles are: An injury or problem with brain development around the ventricles. A blockage or imbalance in the ventricular system which prevents spinal fluid from moving or being absorbed normally.

How can ventriculomegaly affect my child?

Should I worry about mild ventriculomegaly?

Confirmation that mild ventriculomegaly is isolated increases the likelihood that long-term neurodevelopment will be normal, and identification of other CNS malformations makes it more likely that the fetus will have neurologic abnormalities, including developmental delay.

Can Covid cause ventriculomegaly in fetus?

What are the symptoms of ventriculomegaly after birth?

After birth, mild ventriculomegaly may not produce any symptoms or signs. If the condition is severe or caused by worsening hydrocephalus (CSF buildup in the brain), your baby may have one or more of these symptoms: How Is Ventriculomegaly Diagnosed?

What is ventriculomegaly in newborns?

Fetal ventriculomegaly (VM) refers to the enlargement of the cerebral ventricles in utero. It is associated with the postnatal diagnosis of hydrocephalus. VM is clinically diagnosed on ultrasound and is defined as an atrial diameter greater than 10 mm.

What is ventriculomegaly and what causes it?

Ventriculomegaly is a condition in which the brain ventricles, or fluid-filled cavities, are enlarged due to build up of cerebrospinal fluid (CSF). CSF is a fluid that protects the brain and spinal cord. The severity of ventriculomegaly depends on how enlarged the brain is.

How is ventriculomegaly treated in utero?

Currently, there are no in utero procedures being performed on fetuses with ventriculomegaly. After stabilizing the newborn, consultation with a medical geneticist and a neurosurgeon is recommended. Postnatal diagnostic imaging of the central nervous system may include computed tomographic (CT) scan and magnetic resonance imaging (MRI).
