Ventriculomegaly is a condition in which the ventricles appear larger than normal on a prenatal ultrasound. This can occur when CSF becomes trapped in the spaces, causing them to grow larger. Ventricles develop early in pregnancy and can be seen on prenatal ultrasound in the second trimester, at about the 15th week.
Enlargement of the ventricles may occur due to many reasons, such as loss of brain volume (perhaps due to infection or infarction), or impaired outflow or absorption of cerebrospinal fluid from the ventricles, called hydrocephalus or normal pressure hydrocephalus associated with conspicuous brain sulcus.
In a normal fetal brain, the ventricles are less than 10 mm wide. When the ventricles are between 10-mm and 15-mm wide, the baby is diagnosed with mild ventriculomegaly. If the ventricles are more than 15 mm wide, the enlargement is considered severe.
If your child has mildly enlarged brain ventricles or ventriculomegaly without other complications, the condition may resolve on its own. When hydrocephalus is more severe or progresses, timely treatment is important.
Hydrocephalus is the abnormal enlargement of the brain cavities (ventricles) caused by a build-up of cerebrospinal fluid (CSF). Hydrocephalus can be caused by problems with CSF secretion, CSF flow, or CSF absorption.
After a complete evaluation, if the ventriculomegaly is mild and isolated, the outcome is most commonly normal. With isolated moderate ventriculomegaly of 13–15 mm, after a complete evaluation, the outcome is likely to be favorable, but there is an increased risk of neurodevelopmental disabilities.
An abdominal wall defect is an opening in the abdomen through which various abdominal organs can protrude. This opening varies in size and can usually be diagnosed early in fetal development, typically between the tenth and fourteenth weeks of pregnancy.
Abdominal wall defects, specifically the main two types, gastroschisis, and omphalocele, are rare, occurring in about one out of every 5000 births.
Diaphragmatic hernia, one of the other more common major musculoskeletal malformations, has a reported prevalence of 3 to 4 per 10,000 live births. It also carries a high mortality with a reported rate as high as 43%.
No genetic mutations are known to cause an abdominal wall defect. Multiple genetic and environmental factors likely influence the development of this disorder. Omphalocele and gastroschisis are caused by different errors in fetal development. Omphalocele occurs during an error in digestive tract development.
The first is usually at around 8 to 14 weeks and is sometimes called the 'dating scan' because it can help to determine when the baby is due. This first scan may be able to detect problems with your baby's spine that could indicate spina bifida if the condition is severe.
