Brain cysts are typically caused by the abnormal accumulation of fluid within the brain. This buildup can occur due to various factors, especially during development or as a result of injury.
Here's a more detailed breakdown of the causes:
- Developmental Issues:
- Many brain cysts form during the early stages of fetal development, specifically within the first few weeks of gestation. These are often congenital, meaning they are present at birth.
- Trauma:
- Head injuries or other forms of trauma to the brain can lead to the formation of cysts. This is because the trauma can disrupt the normal tissues and cause fluid to collect.
- Other Potential Causes: Although not explicitly stated in the reference, some other possible causes could be:
- Infections
- Tumors
- Genetic conditions
While the exact cause of some brain cysts remains unknown, these are the most common factors contributing to their formation.
