Vascular plexus cyst: causes and treatment

A vascular plexus cyst is called education in the brain, which is detected on the ultrasound of the fetus on the 6-7th month of its development. After which she must disappear and never again remind herself of herself. However, after receiving the results of the study, the pregnant woman begins to worry and consider this a deviation. In fact, this is not so. Such a cyst, which originated in the brain during intrauterine development, is not a threat to the child. Neither his health nor his development is in danger.

Differentiate it with a cyst that has a vascular origin. Namely, it is formed in the substance of the brain after a stroke, an aneurysm, an infection. That is, this is a consequence of the pathology that has occurred in the body. In this article, we'll figure out what the cyst of the vascular plexus is.

Description of education

The cyst in the vascular (choroid, choroid, villous) plexus is formed not so often. In general, it is only 1-3% of all pregnancies that are under observation. This education should disappear by the 27-28th week of pregnancy. Half of the cysts are bilateral. But there are cases when the cyst is visualized before delivery. This is also nothing to worry about.

The fruit is not in danger. In addition, if it is found later in a newborn or in an adult (very rarely in a person's lifetime), it does not matter. The cyst of a vascular plexus can be a little, it in any way is not reflected in the forecast.

What is this vascular plexus cyst? Inside the plexus, the cerebrospinal fluid or cerebrospinal fluid accumulates, which is produced in it. She nourishes the head and back the brain of the fetus. Vascular plexus is a sign of early formation of the central nervous system in the embryo, and there are two of them, like the cerebral hemispheres (right and left).

Science does not know for what reason the fluid accumulation is localized in a certain place. Understand this does not make sense. After all, this cyst of the vascular plexus in the fetus does not really matter. It is called so, because on an ultrasound study the cluster is visualized in this form.

Is there a link with the pathology of intrauterine development?

Medical literary sources sometimes provide such information that the connections between the vascular plexus cyst and some intrauterine pathology exist. This can lead, for example, to a genetic mutation.

Where the cyst of the vascular plexus is localized (on the right side, on the left or on both sides), it does not matter. It is important to note that there is a connection, but it is reverse. That is, the cyst of the vascular plexus does not lead to developmental anomalies, but on the contrary, congenital dysplasia of the fetus causes the formation of cysts in the vessels. But these formations are not necessarily accompanied by abnormalities and pathological processes.

What accompanies the cyst of the vascular plexus in the newborn?

Consider the most commonly diagnosed genetic defect, accompanied by the presence of a cyst. It's about Edwards syndrome or trisomy 18. For a given anomaly 18, a pair of chromosomes does not diverge, and one more chromosome 18 is added to it. Thus, there are normally two of them, and for a given disease, three are obtained. In the embryo as a result, the genotype consists of 47 chromosomes.

A copy of the 18 chromosome can cause the death of the fetus, or at birth, the baby will have multiple defects and anomalies. This leads to:

• Neural tube defect;
• Feet-hammers;
• Torsion of fingers on hands;
• Gigromo cysts;
• Hydrocephalus;
• Micrognatia;
• Foot rocker;
• Limited growth.

There are also trisomy 21 or Down's disease, but for some reason the cyst of the vascular plexus of the brain in this disease is formed less often.

The significance of the cyst is zero even in the presence of Edwards syndrome, since it is the deviations that accompany this developmental anomaly that are important.

Features of the vascular plexus cyst

So, according to the aforesaid, we can draw the following conclusions:

• No value, right cyst or left;
• It does not matter whether it is single or is represented by several small entities;
• While it is safe;
• It has no function;
• Does not participate in any vital processes;
• Does not grow and does not degenerate.

Pregnant women should not be intimidated by the diagnosis of the "cyst of the vascular plexus of the brain" or consider it another cystic formation. Names may be similar, but they are of different locations and genesis.

Other vascular cysts

It is important to note that in the later stages of pregnancy other vascular structures can be detected. On the ultrasound of the fetal brain, the cyst of the vascular plexus is not visualized at all. What can it talk about?

Such cystic formations testify in this case that the mother has had an infection or she still has it. Such ailments include cytomegalovirus and herpes virus.

But these are not cysts of vascular plexuses of the brain in the fetus.

Vascular and Ramolytic (located in the substance of the brain) cyst, which is found in later terms, indicates that the brain is already formed and it causes cystic cavity due to the virus.

A newborn child can become infected with a virus when passing through the mother's birth canal. Then the cystic formation, the plural, most often located in the temporal and frontal areas of the brain, will be revealed after birth. If the cyst originates from the foci of necrosis, it is called a cyst.

Nervous tissues become necrotic because of herpes or cytomegalovirus damage. Cysts of vascular plexuses of the lateral ventricles are not formed.

Neurosonography

A microcyst of the vascular plexus can be detected on an ultrasound examination when performing neurosonography. Each child is supposed to undergo such diagnostics for up to a year. On ultrasound, neurological disorders are determined.

Neurosonography is mandatory in the following cases:

• With birth trauma.
• In case of suspected intrauterine infection.
• With severe pregnancy.
• In case of premature birth.
• With deviations in the newborn in weight and size.
• In the presence of severe violations of the structure and shape of the head, with anomalies in the anatomy of the organs.

Forecast

The reason, localization and size of the cyst affect the prognosis of the pathology. Most often, PCR diagnostics are prescribed in order to identify a viral agent. If the analysis is positive, then certain therapy and further control is required.

In three months, then in six months and in a year it is necessary to do ultrasound of the brain (neurosonography) to the baby. The prognosis is most often favorable regardless of the detected viral lesion. This education disappears about a year and does not remind of itself. There are no relapses.

If we talk about the remediation cyst, it can also disappear without a trace in infancy. Otherwise, if it occurs for other reasons, it behaves differently. But then you can not call it a cyst. This formation arises from the violation of the walls of the vessels, and is located in the brain tissues.

The provoking factors

The pathological cyst can be formed due to other factors:

• Infections.
• Generic and other injuries.
• Micro stroke.
• Hemorrhagic stroke (cyst replaces hematoma, formed as a result of vascular damage).
• Ischemic stroke (a remission cyst of vascular origin just arises as a result of necrosis).
• Aneurysms.

Most often, if the vascular wall is damaged, it will be arterial. After all, in this process, the veins do not participate.

Clinical signs

A hematoma, a stroke, an aneurysm can provoke a cyst in the brain. In some cases, there are no signs of this formation, and it can be detected only after the death of a person. But together with the cyst, formed from the virus, it can give some symptoms:

• Signs of hypertension in newborns.
• A feeling of compression of the brain, headaches.
• Some hearing and vision impairment.
• Minor movement coordination disorder.
• Epileptic seizures, which are considered the most serious consequences.

Cysts of the vascular plexus of the ventricle do not give such symptoms.

Additional symptoms

In addition, constantly compressed brain tissue can lead to other signs:

• Aching constant pain in the head of varying intensity and duration;
• Disturbed work of organs providing hearing, smell and vision;
• Drowsiness or, conversely, insomnia;
• Problems with motor coordination;
• Hypotonic muscle; Sensation of pulsation and noise in the head, increased pressure inside the skull;
• Sudden frequent fainting and convulsions;
• Tremor;
• Regurgitation;
• Pulsations, felt in the fontanel, swelling;
• Local paralysis of the hands or feet, complete numbness of the limbs.

The appearance of these clinical signs is provoked by squeezing adjacent tissues. Normal functioning is impaired in the brain. This happens when the cyst is large or is too close to the important centers of higher nervous activity. Transforation leads to impaired blood circulation and hypoxia.

Methods of treatment

Any special treatment for cyst of the brain, as well as with the vascular plexus cyst, is not required. But in the detection of herpes, cytomegalovirus or other infection, antiviral therapy is prescribed. If there are epileptic seizures, then the reception of drugs with anticonvulsant properties is indicated.

It should also be noted that in the case when conservative treatment does not work (the cyst of the vascular plexus of the fetal brain is too large, for example), one resorts to surgical intervention. The hearth is eliminated by the operation. After that, as a rule, all the symptoms go away.

With mild symptomatology and rare complaints of the patient for dizziness, headache, which has a squeezing character, he is prescribed a long-term course "Tsinarizina" and "Cavinton." Drugs can significantly improve the supply of the brain with oxygen, improve blood circulation, normalize well-being. Carry more often well, side effects do not cause. But individual intolerance is possible.

We examined in detail the cyst of the vascular plexus, as well as its main differences from other cystic formations.
