Arachnoid-cysts-of-the-brain

Brush called a bubble, which is filled with liquid. Arachnoid cysts of the brain has received such name in the location – this formation is localized in the arachnoid membrane of the brain. It is formed after cleavage or formation of a so-called pocket soft lining of the brain. This formation is filled with fluid which circulates in the brain.

It should be noted that the cyst – a fairly common phenomenon. According to statistics, about 4% of people faced with such entities. In most cases, the cysts are small in size, are not associated with any symptoms, and therefore do not require special treatment. The most common cysts occur in men, and such a diagnosis often pose as adults – this is due to the fact that early diagnosis is difficult due to the lack of characteristic features of this education.

Types of arachnoid cysts

The walls of an arachnoid cyst are formed either by cells of the brain’s arachnoid membrane (primary cyst), or by scar collagen (secondary cyst). There are two types of arachnoid cyst:

  • Primary or congenital arachnoid cyst is the result of abnormalities in the development of the brain membranes in the fetus as a result of physical and chemical factors (drugs, radiation exposure, toxic agents);
  • Secondary or acquired arachnoid cyst is the result of various diseases (meningitis, agenesis of the corpus callosum) or a complication after injuries, surgery (bruises, concussions, mechanical damage to the external membranes of the brain).

Symptoms of arachnoid cysts of the brain

Diagnostics arachnoid cysts of the barin

Various methods are used to diagnose an arachnoid liquor cyst (a cyst filled with liquor). The main ones are magnetic resonance imaging and computed tomography to detect cystic formation, determine its localization and size. Intravenous contrast administration allows differentiating the arachnoid liquor cyst from the tumor (the tumor accumulates contrast, the cyst does not).

You have to remember that kanhaiyalal cyst is often a consequence of another disease. Most often, the cyst grows due to neurologic diseases or when the internal organs function abnormally. To identify an arachnoid cyst, the following diagnostic methods are used:

  • blood Tests to detect viruses, infections, and autoimmune diseases;
  • blood tests for clotting and cholesterol levels;
  • Doppler studies can detect vascular patency disorders, resulting in a lack of cerebral blood supply;
  • Blood pressure monitoring, which records pressure fluctuations during the day.
