Question

Recently, a family member has been diagnosed with pediatric brain abscess, and the family is very anxious about this, not knowing what kind of disease it is. There are questions about the seriousness of the condition, the treatment methods, and whether it is easy to treat.

Answer

Pediatric brain abscess, also known as arachnoid cyst, can be categorized into two types: congenital and acquired. Congenital cysts are problems present at birth, while acquired cysts are caused by factors such as trauma, inflammation, or widespread adhesions of the arachnoid. This benign brain cyst has an arachnoid wall and contains fluid resembling cerebrospinal fluid. The cysts typically locate on the surface of the brain and are closely connected to the subarachnoid cavity but do not invade brain tissue. Most cases are solitary, with a few being multiple, and they are commonly found in the brain and cistern areas. Larger cysts may compress brain tissue and skull bones.
