Associated Conditions & Findings
Polymicrogyria
Polymicrogyria is a malformation where the brain develops too many small folds.
In short: Polymicrogyria
- It is a type of cortical malformation.
- It can be associated with encephalocele.
- It can affect development and seizure risk.
- It is identified on brain imaging.
What it is
It is a malformation of cortical development in which the brain forms an excessive number of small folds (gyri). It is identified by its characteristic appearance on brain imaging.
Understanding Polymicrogyria
As a cortical malformation, polymicrogyria can be associated with encephalocele and may affect development and seizure risk depending on its extent and location. Because the abnormal folding reflects altered cortical development, its impact varies, and the team considers it alongside the child's overall picture.
Why it matters
Understanding polymicrogyria helps families interpret imaging descriptions of abnormal brain folding and see why such findings are part of assessing development and seizure risk.
Common questions
What is polymicrogyria?
A malformation with too many small brain folds.
Can it occur with encephalocele?
Yes, in some cases.
What can it affect?
Development and seizure risk.
Bottom line
Polymicrogyria is a malformation of too many small brain folds that can accompany encephalocele.
