arachnoid cyst treatment in Iran
Arachnoid cysts are cerebrospinal fluid-filled sacs that are located between the brain or spinal cord and the arachnoid membrane, one of the three membranes that cover the brain and spinal cord. Primary arachnoid cysts are present at birth and are the result of developmental abnormalities in the brain and spinal cord that arise during the early weeks of gestation. Secondary arachnoid cysts are not as common as primary cysts and develop as a result of head injury, meningitis, or tumors, or as a complication of brain surgery. The majority of arachnoid cysts form outside the temporal lobe of the brain in an area of the skull known as the middle cranial fossa. Arachnoid cysts involving the spinal cord are rarer. The location and size of the cyst determine the symptoms and when those symptoms begin. Most individuals with arachnoid cysts develop symptoms before the age of 20, and especially during the first year of life, but some people with arachnoid cysts never have symptoms. Males are four times more likely to have arachnoid cysts than females.
What are the arachnoid cyst symptoms?
Some arachnoid cysts never present a problem, but others can cause symptoms by putting pressure on the brain. Depending on the size and location of the arachnoid cyst, symptoms can include:
- Nausea and vomiting
- Lethargy, including excessive fatigue or low energy
- Visible lumps or protrusions from the head or spine
- Developmental delays
- Hydrocephalus due to obstruction of normal cerebrospinal fluid circulation
- Endocrine (hormone-related) issues, such as early onset of puberty
- Involuntary head bobbing
- Vision problems
How are arachnoid cysts diagnosed?
Arachnoid cysts are usually diagnosed with a complete exam and imaging tests to see the cysts. These tests may include:
- Computed tomography (CT) scans – CT scans use x-ray equipment and powerful computers to create detailed images of the head and brain.
- Magnetic resonance imaging (MRI) – MRI uses a combination of electromagnets and radio waves to take detailed images of the brain.
arachnoid cyst treatment in Iran
An arachnoid cyst rarely causes symptoms. If your child has a cyst without symptoms, the doctor may just watch the cyst to make sure it does not change size.
If an arachnoid cyst is causing symptoms, your child may need surgery to remove it. Depending on your child’s needs, the neurosurgeon will recommend 1 of 2 surgeries to remove the cyst.
- Open the cyst (fenestration)
Your child’s neurosurgeon makes a small cut (incision) near the arachnoid cyst and takes out a small piece of the skull bone. Then the neurosurgeon puts a small, flexible tube called an endoscope through the incision. The endoscope has a tiny light and a camera that allows the neurosurgeon to see the cyst. The neurosurgeon uses the endoscope to make a hole in the cyst and open it up (fenestration).
Once the arachnoid cyst has been opened, the fluid inside drains out of the cyst into other areas of the brain that contain cerebrospinal fluid (CSF). Your child’s body reabsorbs the fluid from the cyst.
- Put a shunt into the cyst
A shunt is a tiny tube (catheter) that drains CSF from one place in the body to another. Learn more about shunts.
After your child’s neurosurgeon makes a small cut near the arachnoid cyst, they place the shunt into it. The shunt drains the fluid from the cyst into another part of your child’s body, like the belly (abdomen). Once the fluid is in the belly, your child’s body reabsorbs it.
10 common questions about arachnoid cyst treatment in Iran
1Do arachnoid cysts require surgery?
Most arachnoid cysts are stable and do not require treatment. ... Arachnoid cysts are diagnosed with a CT or MRI scan. Treatment, if necessary, involves draining the fluid through surgery or shunting.
2Can an arachnoid cyst go away on its own?
After rupture, subdural effusion must develop around the cyst. As this effusion is absorbed, the fluid in the cyst drains away, after which the cyst becomes smaller and gradually disappears. This supports the possibility of a “natural cure” for arachnoid cysts without surgical intervention.
3Is an arachnoid cyst dangerous?
Untreated, arachnoid cysts may cause permanent severe neurological damage when progressive expansion of the cyst(s) or bleeding into the cyst injures the brain or spinal cord. Symptoms usually resolve or improve with treatment.
4Is arachnoid cyst life threatening?
Are Arachnoid Cysts Life-Threatening? Arachnoid cysts are benign fluid-filled sacs that form between the arachnoid membrane and the central nervous system. ... The most severe form of presentation can lead to bleeding (hemorrhage), damage to the central nervous system and sometimes even death
5What can happen if a cyst is left untreated?
If left untreated, benign cysts can cause serious complications including: Infection – the cyst fills with bacteria and pus, and becomes an abscess. If the abscess bursts inside the body, there is a risk of blood poisoning (septicaemia)
6Can you die from an arachnoid cyst?
None of the children died or had major disability. As more children with arachnoid cysts are identified, neurosurgeons need the best possible information on risk factors for rupture or bleeding. The risk that an arachnoid cyst will rupture or bleed has been estimated somewhere between two and five percent.
7Does arachnoid cyst grow?
Primary, or congenital, arachnoid cysts are usually caused by an abnormal growth of your brain and spinal column while you're developing in utero. The exact cause of this growth is not known. It might be genetic. Secondary arachnoid cysts, also known as noncongenital arachnoid cysts, can be caused by several things
8Can you feel an arachnoid cyst?
A variety of additional symptoms occur in some individuals with arachnoid cysts depending upon the size and location of the cyst. Most cysts occur near the middle fossa region of the brain. Such symptoms include lethargy, seizures, vision abnormalities and hearing abnormalities
9Can an arachnoid cyst turn into cancer?
Brain cysts are fluid-filled sacs that may form in the brain. They can be benign (not cancer) or malignant (cancer). ... These include arachnoid, colloid, dermoid, epidermoid, pineal, infectious, and tumor cysts. Even when brain cysts are noncancerous, they may press against brain tissue and cause symptoms.
10Can arachnoid cyst cause eye problems?
Although arachnoid cysts are benign and asymptomatic lesions, patients with posterior fossa arachnoid cysts often complain of headaches, gait disturbance, and ataxia due to the local mass effects on the cerebellum. ... After 7 days, the patient revisited our hospital in a state of near-blindness
