Types of brain cysts

  1. Arachnoid cyst of the brain. This cyst is located in the arachnoid membrane of the brain. The cyst cavity is filled with cerebrospinal fluid. Most often, an arachnoid cyst can be found in adolescents and young boys
  2. A colloid cyst. A cyst is formed due to embryogenesis. This cyst can stay in a person’s head all their life and not bother them. This disease can be detected without diagnosis if the cyst blocks the current liquor. The cyst may be the cause of hydrocephalus. Colloidal cyst should be detected as early as possible, because it causes sudden death of a person.
  3. Dermoid cyst. This cyst appears in a person even in childhood. It begins to grow suddenly and press on certain parts of the brain. The cyst looks like a bubble, inside of which are different human tissues: hair, nails, teeth, fat. It is better to remove such a cyst immediately with an operation.
  4. Cyst of the pineal gland. The cyst develops in the epiphysis of the brain. There is a cavity inside the cyst. A cyst disrupts a person’s vision, coordination of movements, and metabolic processes in the brain. Cyst of the pineal gland may be the cause of hydrocephalus.

Research of cyst of brain:

  • Doppler study of blood vessels. This procedure is performed to detect narrowing of blood vessels that are present in the brain. Their narrowing can cause a lack of oxygen in the brain and is one of the reasons for the formation of cysts.
  • Analysis of blood clotting and cholesterol.
  • Blood pressure monitoring.
  • Blood tests for autoimmune diseases and infections. This study was conducted when multiple sclerosis, neuroinfections, and arachnoiditis were suspected.
