On an MRI report, what does mild inferior cerebellar tonsillar ectopia mean?

Possible Chiari: This statement means that a portion of your cerebellum (the cerebellar tonsils) is sitting lower down than is normal. If your cerebellar tonsils are low lying they can sit in an opening in your skull and get pushed on by your skull. This condition is called a Chiari I malformation. It can also cause compression on the brainstem. People whose cerebellar tonsils sit 12 mm low tend to have symptoms.

Cerebellum (Definition)

An area in the back of the brain that helps coordinate movement, speech, and eye movements. It has connections to the frontal lobes also and may play a role in helping you ...Read more

FOR MY MOM INFERIOR CEREBELLAR TONSILLAR ECTOPIA 1.2CM BELOW FORAMEN MAGNUM. THERE IS A ASYMETRIC HERNIATION OF CEREBELLAR TONSILS RIGHT-1.2CM LEFT-8MM?

FOR MY MOM INFERIOR CEREBELLAR TONSILLAR ECTOPIA 1.2CM BELOW FORAMEN MAGNUM. THERE IS A ASYMETRIC HERNIATION OF CEREBELLAR TONSILS RIGHT-1.2CM LEFT-8MM?

Chiari malformation: Arnold chiari malformation type 1 is defined by cerebellar tonsils that extend below the foramen magnum. The symptoms range from none to headaches, numbness, pain and weakness. The condition can become life threatening when cerebrospinal fluid is blocked. It is important to see a neurosurgeon with experience treating this disorder to discuss the therapeutic options.

Rec direct consult.: Digging into the details of this exam should be done in consult with a radiologist &/or your neurologist. Free free to upload your MRI images and schedule a concierge appointment and I'd be happy to go through the findings and terminology with you.

Mild cerebellar tonsillar ectopia 5 mm?

Chiari malformation: The definition for chiari malformation is the presence of cerbellar ectopia of greater than 3 mm below the foramen magnum. Thus you fulfill at least part of the criteria for chiari 1 malformation. The key is the presence of symptoms. If present, then phase-contrast mr flow studieshave a role in determining whether symptomatic chairi malformation patients may benefit from surgical intervention.

What exactly is cerebellar tonsillar ectopia?

Tonsillar ectopia: The cerebellum is at the lower back of your brain, and is mainly responsible for motor coordination. The tonsils are at the midline of your cerebellum and sometimes they can extend a bit lower than normal. That's called tonsillar ectopia. They may be asymptomatic, or they could cause symptoms like headache, pain, and other neurologic symptoms.

Hi doctors, was just wondering what is cerebellar tonsillar ectopia?

Hi doctors, was just wondering what is cerebellar tonsillar ectopia?

Chiari 1: Tonsillar ectopia, slight descent of the cerebellar tonsils and Chiari I malformations, disorders observed in older children and adults and are believed to be an acquired form of the Chiari malformations. This entity is different from the other Chiari malformations in that hydrocephalus plays no role in its evolution

Diagnosed with mild cerebellar tonsillar ectopia, I am experiencing headaches while excercising. Should I be concerned?

Diagnosed with mild cerebellar tonsillar ectopia, I am experiencing headaches while excercising. Should I be concerned?

Co-morbidity: Unlikely that your headaches are caused by the ectopia, and other causes, such as dental/jaw, sinus/nasal, cervical, thyroid, could all be considered. But, may well be migraines which are exercise triggered.

What does it mean? My report says the report says there is mild cerebellar tonsillar ectopia with tonsils extending 5mm through the foramen magnum

Chiari Malformation: Well at least one of the features is present. Low lying cerebellar tonsils are dipping into the foramen magnum which is the big hole at the base of the skull that allows the spinal cord to pass up to the brain. It means no more trampolines, bungee cord jumping or roller coaster rides for you. You don't want the cerebellar tonsils to be forced down further. Look up arnold chiari malformation, .

When an MRI reads borderline cerebellar tonsillar ectopia, is there a possibility of it going down some more? Any physical activity restriction needed

When an MRI reads borderline cerebellar tonsillar ectopia, is there a possibility of it going down some more? Any physical activity restriction needed

Low cerebellar tonsi: Borderline cerebellar tonsillar ectopia (low lying) is very common and has no clinical significance. There is no activity restriction. It should not progress unless transiently after a spinal tap. You should let your doctor know if you are going for a spinal tap.

My fiancé just got diagnosed with Bilateral cerebellar tonsillar ectopia. Our doctor did not say much, but im extremely worried and don't know what to?

Educate yourself.: Here is an article by the National Organization for Rare Disorders: https://rarediseases. Org/rare-diseases/chiari-malformations/ Take care

A recent mri showed cerebellar tonsillar ectopia up to 12 mm, does this along with having a lot of the symptoms of chiari mean that chiari is likely?

A recent mri showed cerebellar tonsillar ectopia up to 12 mm, does this along with having a lot of the symptoms of chiari mean that chiari is likely?

Meets Chiari I def: Tonsilar ectopia greater than 5-6mm below the foramen magnum is considered a Chiari I malformation. Whether symptoms are associated is more individual, but usually at 12mm and greater, most are found to have associated symptoms.

I have mild cerebellar tonsillar ectopia less than 5mm. I do have various things wrong that could be conected. But gp is not sure. What is my prognose?

I have mild cerebellar tonsillar ectopia less than 5mm. I do have various things wrong that could be conected. But gp is not sure. What is my prognose?

Chiari: This sounds like a "borderline" chiari malformation. These are generally not serious as long as there are not other brain abnormalities or spinal abnormalities. Thus further imaging is likely needed. However, if this is normal then your prognosis is good and you will not likely need further treatment.

Mild Cerebellar tonsillar ectopia 4mm, but been diagnosed w/ pseudotumor cerebri for over a year. My mother also has Chari, do I??

Yes mild form: You will need to be followed by a good neurologist. Symptoms may never appear if all remains stable.

A recent brain mri showed that I have cerebellar tonsillar ectopia but did not show a syrinx. Is it possible that it could show on a different mri?

A recent brain mri showed that I have cerebellar tonsillar ectopia but did not show a syrinx. Is it possible that it could show on a different mri?

Possibly: A syrinx does not occur with all Chiari Malformations but regardless, a spinal MRI would be the best imaging to identify a syrinx.

My 9 yr old son was diagnosis with chiari malformation 1. What does "8 mm of cerebellar tonsillar ectopia with tonsillar deformity" mean? Dr wants surgery

My 9 yr old son was diagnosis with chiari malformation 1. What does "8 mm of cerebellar tonsillar ectopia with tonsillar deformity" mean? Dr wants surgery

Description of probl: The "bottom" part of the brainstem leaks back into the spinal cord from the skull. This may pressure the brainstem causing damage. Surgery can fix this. The description refers to how much of the brain is misplaced and at risk.

Daughter is experiencing headache (front, back, down neck and back). She was diagnosed last month with a 4mm mild cerebellar tonsillar ectopia. Last week she had 2 lumbar punctures done with 59ml of spinal fluid removed. Is this related? Cause? Fix?

Daughter is experiencing headache (front, back, down neck and back). She was diagnosed last month with a 4mm mild cerebellar tonsillar ectopia. Last week she had 2 lumbar punctures done with 59ml of spinal fluid removed. Is this related? Cause? Fix?

Be seen: Rather than use HealthTap, you should go back to the neurologist who has been evaluating and/or doing the lumbar punctures. That health care provider has the context on why the LPs were performed, why imaging was done, and the potential other aspects historically that are relevant. Good luck.
