How serious is a brain cyst?
Large brain cysts can block the normal flow of cerebrospinal fluid , which can cause increased pressure on the brain. Cysts can also leak into other areas of the brain, or blood vessels on the cyst’s surface can bleed into the cyst causing a hematoma. If left untreated, cysts can cause neurological damage.
How do you get rid of a cyst on the brain?

What is isolated choroid plexus cyst?
What are isolated choroid plexus cysts and how common are they? A choroid plexus cyst is a small fluid-filled structure within the choroid of the lateral ventricles of the fetal brain . Sonographically, choroid plexus cysts appear as echolucent cysts within the echogenic choroid (Figure 1).
Can choroid plexus cyst cause seizures?
Choroid cysts are best observed on coronal sections on neuroimaging and among the MRI sequences FLAIR is considered to be superior. These cysts can become symptomatic and cause seizures if they increase in size by compressing adjacent structures .
