Hi,

There is not only one single cyst type, there are different types with different content. Also cyst size is important as well, naturally a small cyst doesn't have the same risks as a gigantic one. Generally speaking, in everyday practice the most common type is an arachnoid cyst. There are many common, found in many people and usually remain the same and do not cause any complications, without affecting learning and development, the majority of people lead a perfectly normal life. However to say confidently whether this child belongs to this majority as I said at the beginning more info is needed.

Hope I have answered your query. Let me know if I can assist you further.
