Brain cysts located in the brain are not truly “brain tumors” because they do not arise from the brain tissue itself. Although they tend to be (benign noncancerous), they are sometimes found in parts of the brain that control vital functions.
There are four main types of cysts found in the brain:
Arachnoid Cyst (also called Leptomeningeal Cyst): An enlarged, fluid-filled area of the subarachnoid space that occurs in both adults and children.
Colloid Cyst: Although scientists are not sure of the definitive cause of colloid cysts, most agree that these cysts begin during embryonic development of the central nervous system. Malignant forms are unknown.
Dermoid Cyst: These cysts most likely form during the early weeks of fetal development even though symptoms may not be noticed until years later. They are usually benign.
Epidermoid Cyst (also called Epidermoid Tumor): Often referred to as epidermoid tumors. Likely form during the early weeks of fetal development even though the symptoms may not be noticed until decades later.
