Causes Of Retrocerebral Cysts
Retrocerebral cyst represents intracerebral cyst cavity, which is filled with liquid. The main reason for the development of rectocerebral cyst is cell death of the gray matter, in place of which a bladder filled with the remains of dead cells and intracerebral liquid is formed.
Causes of retrocerebral cyst
The factors which influence the gray matter cell death should be recognized as causes of the disease. These include:
- Stroke, that is, bleeding in the brain, the formation of intracerebral hematomas that cause cell death.
- Poor blood circulation in the brain, i.e. acute or chronic oxygen deficiency of brain cells, causing them to die .
- Surgery on the brain.
- Injuries, including concussion, bruises and others.
- Infectious diseases, such as meningoencephalitis, meningitis, and others.
Symptoms of retrocerebral cyst
Symptomatology of the disease entirely depends on the size of the cyst, its causes and location in the brain. If the cyst is small and its walls do not press on the neighboring parts of the brain the symptoms may not occur. If cyst's growth continues, for example, due to the inflammatory process which occur in it, because of poor circulation, or due to autoimmune processes in the brain, there may occur the following symptoms:
- Headache that is difficult to correct with the help of painkillers.
- Bloating in one;s head.
- Pulsation inside the skull.
- Hearing loss or tinnitus.
- Blurred vision, the appearance of "flies " in front of the eyes, double vision.
- Convulsions or seizures.
- Numbness or partial paralysis of the limbs.
- Poor coordination, gait, loss of balance.
- Loss of consciousness.
Diagnosis and treatment of retrocerebral cyst
Diagnosis of the disease is carried out by means of diagnostic procedures, such as CT and MRI.
If the cyst is small, and does not provoke any symptoms and is found by accident during a routine inspection or diagnosis of other diseases, the treatment is not required and the observation by a neurologist and control of tumor growth are sufficient in this case.
If you have symptoms and the size of the cyst increases, surgery is necessary. Before the operation, there is estimated the size of the cyst, particularly its location and risk of surgery. And then the doctor makes a decision whether to pescribe one of the three types of surgery:
- Endoscopic puncture is the least traumatic type of surgery made using an endoscope. The skull is punctured and through a cyst or pumped liquid is removed through it. This type of operation is not always acceptable because of the peculiarities of the location of cyst.
- Brain surgery with a craniotomy is a traumatic type of operation, which implies a full opening of the skull and the removal of the cyst.
- Bypass surgery is performed in the case there is hydrocephalus, ie, a constant flow of fluid in the cyst. Operation is performed using a shunt, which removes fluid from a cyst an moves it to the natural reservoirs of the body.
