Causes, symptoms and treatment of arachnoid cysts of the posterior cranial fossa

Б.в

An Arachnoid cyst of the posterior cranial fossa is a small cavity, which is filled with liquid. Its walls are composed of special cells of the arachnoid. As a rule, cerebrospinal fluid arachnoid cyst is formed between the brain and its membranes.

Localization of arachnoid cysts

There are two types of this disease: congenital and acquired cysts. The last type can occur as the result of a complex disease: the inflammatory process of the spinal cord or brain, diseases of Morgana, absence of the corpus callosum in humans, and also as a result of surgical intervention. As a rule, on the surface of cysts can be noticed arachnoid scarring.

It shows many statistics, tumors of this type are most often found in men. In this case the cyst develops quite rapidly and growing in size. In women, this phenomenon is more rare, and the tumor growth is several times slower.

It is Interesting that tumor size has a direct effect on manifestation of disease symptoms. If the size of the cyst is very large, it can cause partial loss of hearing or even eyesight. Can occur defects of speech, memory lapses, seizures and so on.

causes of diseases and symptoms

Reasons education archibaldo cysts in the posterior cranial fossa can be very different. It most commonly occurs under the influence of the following factors:

  • inflammation of the membranes of the brain or spinal cord;
  • absence of nerve fibers;
  • no small part of the corpus callosum;
  • mechanical brain injury;
  • brain surgery
  • disease of Morgana and so on.

the Occurrence of cysts from mechanical injury

The Cyst grows in size due to the fact that inside the cavity rapidly increases the amount of fluid. Also affect the development of inflammation of the lining of the brain. Often the impetus for the growth of the cyst becomes even a slight concussion.

Symptoms that indicate the presence of arachnoid cysts are slightly different depending on its size. Sometimes symptoms may be absent, which is extremely rare. If the cyst is congenital, the first signs of problems can manifest themselves closer to twenty years of life.

The Main signs of presence of this type of cyst is considered to be the following:

  • chronic headaches of various degrees and intensity;
  • frequent nausea and/or vomiting;
  • disturbances in coordination of movements;
  • partial or temporary paralysis of one half of the body;
  • if the cyst is big enough, hallucinations;
  • full or partial mental disorder;
  • can bothered by frequent and strong convulsions.

the Presence of cysts in the child

the U.S. head of the child to diagnose cysts

The child this problem can occur as a result of the inflammatory process during fetal development. In addition, in some situations, the cause is trauma during childbirth, certain violations in the child's development at a time when the formation of the embryo, meningitis at a different stage.

If the tumor was found in the child, the doctor needs to constantly monitor its condition and how it develops. If will be noticed that the cyst progresses too quickly, then, as a rule, the decision to completely remove the tumor. To detect the cyst in the cranial fossa in a child is possible only with the help of ultrasound, and therefore, if you notice even minor symptoms, you should contact a specialist for a thorough examination.

Detection of disease in the newborn

If a newborn child found a cyst, it may occur as a result of developing meningitis or other inflammatory process even during prenatal development. In addition, the cause in this case is more often received by the child trauma or congenital disorders.

To Detect the problem in the newborn is possible only by carrying out an ultrasound. It should be remembered that such tumors could not dissolve themselves and therefore need the doctor to control the situation and if necessary, immediately took measures for the removal or treatment of cysts in the posterior cranial fossa in a newborn.

Prenatal development of brain cysts

Tactics and methods of therapy

Treatment usually start when a cyst begins to grow in size and appear the first symptoms that may not indicate its presence. In order to start treatment in time, irreversibly to regularly visit specialists and conduct the desired survey.

If the cystabruptly and progresses quickly, in most cases, treatment can be only surgical.

Thus there is a radical surgical intervention: craniotomy patient, and then the removal of a tumor from the posterior fossa. In practice, such treatment is quite often the cause of serious injury in humans, and therefore used it in extreme cases.

To Remove a tumor from the skull can be the other way, which is used slightly more often. The removal is done by a special drainage tube, through which specialists pumped fluid from the cysts by shunting. But this method is also considered quite dangerous, because there is a high risk of infection.

Another method of treatment is endoscopy. In this case, the tumor is pierced and gently pump her for all content. The injury of the patient in such a situation is considered to be minimal, but it can be used far not in all tumors in the skull of man.

the Operation to remove a cyst in the brain

the Implications and complications

If time does not begin treatment arachnoid cysts of the posterior cranial fossa, the fluid can begin to accumulate fairly quickly that will affect the increase in the size of the tumor, and then it will be to put pressure on the brain. Therefore, you may experience hearing, vision, speech, memory and other things. If the shell of the cyst in late-stage disease will be interrupted, it can lead even to death.

Preventive measures

The Only prevention of disease today is the timely detection of problems. It is very important to start the treatment on time. Also, do not allow the development of different kinds of inflammatory processes in the brain, mechanical trauma and infection in the body.

If the time to detect an arachnoid cyst of the posterior cranial fossa and begin to treat it, the doctors ' prognosis is in most cases more than optimistic. After surgery, the cyst completely and correctly removed, the person quickly recovers, and the presence of tumor in the past does not affect his health, does not affect the hearing, vision, speech and mental capacity.

So watch your health and at the first unpleasant symptoms or suspect the presence of cysts refer to specialists.
