What is Sulcal enlargement?

Ventricular enlargement and sulcal widening were defined as an increase in ventricular size or sulcal size of 3 of 10 grades between baseline and follow-up.

What does Involutional changes of the brain mean?

As some people age, the folded brain tissue starts to shrink, making the spaces between the folds (the sulci) deeper and wider. These are called involutional brain changes. In many people with dementia, the folds are greatly shrunken.

What is the cortical sulci?

Cortical sulci are convoluted regions between cortical folds deeply embedded in the surface of the brain. Deep fissures in the brain, sulci separate functionally distinct regions. They are complex 3D surface boundaries that partition the brain’s anatomy.

Can enlarged brain ventricles be normal?

The brain may shrink in older patients or those with Alzheimer’s disease, and CSF volume increases to fill the extra space. In these instances, the ventricles are enlarged, but the pressure usually is normal.

What can cause enlarged ventricles?

What are the causes of ventriculomegaly?

• a problem that prevents cerebrospinal fluid (CSF) fluid from circulating and being absorbed normally in the brain, which causes hydrocephalus.
• a minor imbalance in fluid circulation and absorption.
• defects in brain development.
• damage or loss of brain tissue.

Is moderate brain atrophy serious?

This loss may be the result of an injury, infection, or underlying health condition. Mild cases of brain atrophy may have little effect on daily functioning. However, brain atrophy can sometimes lead to symptoms such as seizures, aphasia, and dementia. Severe damage can be life threatening.

What do sulci do?

Brain gyri and sulci serve two very important functions: They increase the surface area of the cerebral cortex and they form brain divisions. Gyri and sulci form brain divisions by creating boundaries between the lobes of the brain and dividing the brain into two hemispheres.

How is mild ventriculomegaly treated?

How is ventriculomegaly treated? Ventriculomegaly only needs to be treated if the baby has hydrocephalus, a build-up of cerebrospinal fluid (CSF) in the brain. Treatments for hydrocephalus include: Shunt placement: In this process a small tube is implanted in the brain while the child is under anesthesia.

What is ventricular prominence in the brain?

There are spaces within the brain (ventricles) that are also filled with CSF. 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.

Is Mild ventriculomegaly normal?

The chance that mild ventriculomegaly represents a normal variant decreases with increasing degrees of dilation. Mild ventriculomegaly is likely to represent a normal variant if no other structural abnormalities are noted and if aneuploidy screening or diagnostic genetic testing results are normal.
