Just like a cyst anywhere else in your body, a cyst in the brain is a sphere filled with fluid—much like a balloon filled with water. They may contain fluid, blood, tissue, pus, or tumor cells. Brain cysts are not truly “brain tumors” because they do not arise from the brain tissue itself.
Although they tend to be benign (non-cancerous), they are sometimes found in parts of the brain that control vital functions. Many cysts are formed before birth and slowly grow over the course of years. Some arise as a result of head injury or infection.
There are five main types of cysts found in the brain: Arachnoid, Colloid, Dermoid, Epidermoid, and Pineal. Cysts are diagnosed through use of imaging tests such as CT or MRI.
Cysts can appear in a variety of locations within the brain.
Symptoms depend on the size and location of the cyst and can vary from person to person.
The type, size, and location of the cyst determine how it will be addressed. Treatment methods for the various types of cysts are briefly explained below:
Molecular profiling is the detection of specific genes, proteins, or other molecules in a tumor. This information helps confirm tumor diagnosis, inform treatment options, and predict prognosis.
There are no known molecular markers for cysts.
