In our clinic we have specialists who treat all types of neurological disorders, the best surgeons and professionals to diagnose pathologies in this field. In this article we leave you all the information about Chiari malformation, the types, symptoms, how it is diagnosed and what are the best treatments that exist to treat it.
What is Chiari malformation?
Chiari malformation, or Chiari disease, is a pathology that affects the structure of the skull and cerebellum. In this condition, brain tissue is pressed downward, often by an overly small or deformed skull, causing it to extend into the spinal canal.
Do you have pain that doesn't get better?
Our team of specialists analyzes your case and advises you on the best treatment, whether conservative or surgical.
Request a medical evaluationThis defect produces excessive pressure in the cerebellum and brain stem that can hinder the circulation of cerebrospinal fluid and affect brain functions.
Types of Chiari malformation
Chiari malformation is classified according to the severity of the defect and the patient's anatomy, allowing for a more precise approach to diagnosis and treatment.
Chiari malformation type I
It is considered the mildest case of Chiari malformation. They usually have no symptoms, Therefore, it is normal for it to be detected by “chance” during another study being performed on the patient, or late when the patient begins to present symptoms.
Chiari malformation type II
This type of malformation is characterized by being more serious. Symptoms usually appear during childhood and are associated with cComplications that can be potentially fatal. Patients with a type II Chiari malformation have a increased amount of brain tissue extending into the spinal canal.
This type of malformation occurs from birth and can be detected even before birth, in ultrasounds during pregnancy, which allows immediate diagnosis and surgical treatment to avoid neurological problems in the patient.
Chiari malformation type III
Chiari malformation type III is rare but extremely serious. This case is characterized by an opening in the back of the skull which causes a higher mortality rate, as well as serious neurological problems. Like Chiari type II malformation, this can be diagnosed at birth or even before and requires urgent treatment.
Chiari malformation type IV
This type of malformation, often called cerebellar hypoplasia, involves a problem with the development of the cerebellum. Patients who have a type IV Chiari malformation have the cerebellum in the correct place but, due to some developmental problem, some part of it is missing.
Main symptoms of a person with Chiari malformation
In patients with Chiari malformation type I, it is common for symptoms to be absent or mild. One of the most common symptoms is headache, which tends to be aggravated by actions such as coughing or sneezing.
Likewise, symptoms may vary depending on the severity of compression and accumulation of cerebrospinal fluid that the patient presents. Among the main symptoms that may arise we can stand out:
- balance problems
- Dizziness
- Hearing problems
- Seizures
- Vomiting
- Difficulty swallowing or speaking
- Fine motor problems
- Muscular weakness
In infants, symptoms may include difficulty swallowing, which can lead to irritability during feeding. They may also have a stiff neck, excessive drooling and a weak cry, as well as developmental delays.
Causes and risk factors of Chiari malformation
Chiari malformation is a structural defect of the skull that affects the development and positioning of the back of the brain, particularly the cerebellum. This disorder usually occurs during fetal development, when the skull does not form properly, causing brain tissue to be pushed into the spinal canal.
In most cases, Chiari malformation is a consequence of genetic abnormalities or nutritional deficiencies that occur during pregnancyThe most common genetic alteration is related to mutations that affect the proper development of the skull and brain. Deficiencies in essential nutrients, such as folic acid, can also be a factor in the appearance of this disorder during pregnancy.
In less frequent cases, this malformation can develop due to traumatic head injuries or acquired diseases, such as tumors, that can alter the bone structure of the skull or the normal flow of cerebrospinal fluid.
Are there risk factors for acquiring Chiari disease?
Currently, there is no scientific evidence of the specific risk factors for developing Chiari malformation. However, some studies suggest that there may be a genetic predisposition, which would indicate a genetic component in certain cases.
Diagnosis and treatment of Chiari disease
As we have mentioned previously, Chiari malformation can often be diagnosed with an ultrasound during pregnancy. If you notice any of the symptoms described above in your child, do not hesitate to consult a doctor so that he or she can carry out the necessary measures. diagnostic imaging tests and clinical study necessary to determine the cause of those symptoms.
What happens if Chiari disease is not treated?
Without treatment, Chiari disease can lead to serious complications. As it progresses, debilitating symptoms such as chronic headaches, dizziness, balance problems and muscle weakness can appear. Compression on the brain also increases the risk of hydrocephalus and syringomyelia, a cyst in the spinal cord that affects motor and sensory function. In addition, breathing and swallowing difficulties can arise in more advanced cases. Therefore, although not all cases require surgery, medical follow-up is essential to prevent complications and maintain a good quality of life.
Treatment and surgery for Chiari malformation.
In milder cases of Chiari disease, the specialist may opt for close monitoring without immediate surgical intervention, monitoring any possible progression of symptoms. However, when the pathology progresses and symptoms that affect quality of life appear, surgery becomes the most effective treatment option.
The most common surgery for this condition is decompression, which involves removing a small portion of bone at the base of the skull to relieve pressure on the cerebellum and brain stem, improving the flow of cerebrospinal fluid.
Although this technique is the most used, the treatment must always be adapted to each patient, which highlights the importance of attending a neurosurgery clinic to analyze the case and develop a tailored approach plan for each person.
Our team of neurology specialists is at your disposal to evaluate your case and develop a personalized treatment plan. Do not hesitate to contact us so we can provide you with the best care.

Hello, I had Chiari type one surgery because my head hurt a lot, I was fine for a month or so and my head started to hurt again but harder, I used all the painkillers there are and none of them calmed me down, until I They had to give me morphine for the pain, now I live with morphine because there is no other medication that calms my headache, I did a lot of studies and they recommended a neuro stimulator, which I didn't want to take because another patient I had the same thing that I told me that Hera is torture to use
Hello Omar, we are sorry that you are going through these circumstances. We are waiting for you at our clinic to evaluate your case in detail.
You can request your appointment by calling 910 053 900.

Indeed, the neurostimulator brings many complications. Don't get it, and the relief is minimal. They put one in me, and it only infected my brain and spinal cord.
Good evening, I'm Maria. I'm very worried because I was diagnosed with Chiari deformation. What I feel is pressure in my brain and tingling in my hands. They referred me to a neurologist, but my concern is that I'm receiving chemotherapy treatment. I don't know what to do. I'm very worried.
Hello Maria,
We are very sorry that you are going through this difficult time. Feeling worried is completely natural, especially when dealing with two major medical conditions at the same time. Please let your oncologist know about this and see your neurologist as soon as possible for clarification. It is important to take care of your emotional health, rest, and prioritize activities that do not exacerbate symptoms. Seek support from loved ones or specialists.

My name is Rosmely, I have Chiari syndrome, but I have another pathology, which is muscular dystrophy. I have type I. The symptoms are very similar, that's why I didn't know I had it until my dystrophy caused me to have some tests done on my head, but I do have a lot of IOS and they observed it there.
Hello Rosmely,
Thank you for sharing your experience. We understand that having both Chiari syndrome and muscular dystrophy type 1 can be confusing due to the similar symptoms. It's essential that you continue with specialized medical follow-up for proper management of both conditions, as each may require specific treatments or approaches.
It's recommended that you continue with your regular checkups and appointments to ensure any changes in your condition can be identified and treated promptly. If you need a second opinion or more guidance on how to manage both conditions, don't hesitate to contact us.
Good morning. My head has been hurting all the time. They did an MRI. They diagnosed me with vascular migraines and tonsils that have been out of place since birth. I won't see a neurologist for the migraines, but they're referring me to neurosurgery, but they say it doesn't require surgery. I don't know if this could or has anything to do with my pain. I'll go see what they say.
Hello Rachel,
We're sorry you're experiencing this pain. It's good that you've been diagnosed with vascular migraines, and that surgery isn't necessary. As for your tonsils, although they're not directly related to migraines, it's always helpful to follow the advice of specialists.
We suggest you continue with your appointments to obtain a more complete evaluation and see what treatment options are available to you.
Good luck and we hope you find relief soon.
Hello, good afternoon
My daughter is currently 22 years old and was diagnosed at 17, which the neurologist only said that surgery was necessary without providing further information.
Afterward, despite the many bad things that happened, we didn't seek any other treatment option. It's worth noting that the doctor told us she wouldn't have to undergo surgery until she was 40, and she didn't offer any treatment, just the diagnosis.
Currently my daughter is having episodes of tremors in her body and a few days ago her body collapsed giving her a kind of epileptic attack, something that had never happened to her before.
We had to urgently find a neurologist to review his case.
But we still have no information about what will happen.
Is it possible that I need to undergo an operation urgently?
Hello,
We understand how difficult it must be to lack clear information about diagnosis and treatment. Chiari malformation can manifest itself in different ways, and the therapeutic approach varies depending on the severity of the symptoms. The episodes you mention, such as tremors and body collapse, could indicate that the condition is becoming more pronounced, necessitating closer monitoring.
It's essential that a specialized neurologist thoroughly evaluate your case to determine whether surgery is necessary and urgent, or if other treatment options exist. We recommend staying in close contact with your specialist to obtain an accurate assessment and decide on the next step.
Greetings.
My name is Daisi. I was diagnosed with Chiari type 1 a month ago. I am worried and have fallen into depression. My question is, will I have surgery because when I am lying down in the morning I have energy, but when I start walking for about an hour I feel weak in the body and my energy almost drops to zero.
Hello Deysi,
Thank you for sharing your experience. A diagnosis of Chiari type 1 can be very worrying, but it doesn't always require surgery. The decision depends on the intensity of your symptoms and the findings from tests such as an MRI. The weakness you describe may be related to this condition, but it's essential that a specialized team assess your case individually. If you wish, you can schedule an appointment with us by calling 91 005 39 00. We are here to help and support you throughout this process.

WHAT IS THE PROGNOSIS FOR QUALITY OF LIFE FOR A TYPE 2 CHIARI, DETECTED AT 20 WEEKS, IF SURGERY IS REQUIRED IN UTERUS, HOW WILL IT AFFECT THEIR QUALITY OF LIFE?
Hello Mirian,
The prognosis for quality of life in Chiari type II diagnosed during pregnancy can vary greatly depending on the degree of involvement, the presence of other associated malformations, and the response to treatment. Intrauterine surgery can sometimes improve certain aspects of neurological and motor development, but it does not always eliminate all complications.
It is essential that your case be evaluated by a specialized medical team who can explain in detail the potential benefits, risks, and limitations of intrauterine surgery. Each case is unique, and a specialist evaluation is key to making the best decision.
Greetings.
