Mri Chiari Malformation
Then leave it alone: Various cerebellar malformations fron I to IV or v depending extent, to severe symptoms in type I just cerebellar tonsils herniate to spinal canal as shown (most likely you have this) most of the time asymptomatic other have symptoms need complex corrective procedures, . ...Read more
Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
Went to ent for tinnitus and found out through mri I have chiari malformation. Dr didn't seem concerned but is it serious?
I had a brain MRI stating cerebral tonsils terminating 5mm below foramen magnum. C spine mri says no chiari malformation. Is it chiari or not?
5mm: Is a borderline measurement. There is some variability between investigators regarding the precise range of normal. In the abscence of any other findings, most authors would consider 5mm at the upper limit of normal. Some would term this "benign tonsillar ectopia", an incidental and asymptomatic finding. Some would consider 5mm indeterminate. As an isolated finding, it is not diagnostic of chiari ...Read more
My son of 13 yrs had bad throat infection. Now he's been tasting blood in throat. Main symptom bad ear pain for months. Terrible pressure in ears when bends down. ENT not found any prob with ears few months ago. MRI shows possible chiari malformation, no
Suspecting chiari malformation. Mri on wed. Have been having tension/neckaches and now nausea but I am 6wk pregnant. Safe to wait til wed for mri?
Basically,: Chiairi malformations are characterized by herniation of the cerebellar tonsils through the foramen magnum into the cervical spinal canal. Depending on the type of malformation there may be other associated findings. The graphic shows the changes at the level of the skull base. ...Read more
Chiari malformation shows up on a MRI as an extension of the cerebellar tonsils (the lower part of the cerebellum) into the foramen magnum, with or without involving the brain stem. Normally, only the spinal cord passes through this opening. For more info please refer to chiari and syringomyelia foundation

Recently found through MRI that I have a chiari malformation just wondering if this condition always gets progressively worse or if I can live with it?
Not all progress: Not all chiari malformations cause progressive problems. Early signs are recurrent headaches. If this is an issue, contact a neurologist or neurosurgeon. ...Read more
I have an chiari malformation type 1. What symptoms would I have if I am not circulating enough csf? I have a MRI in two weeks to see.
Shoulder area numb: The lack of CSF flow around the chiari area is thought to raise the risk for a fluid collection inside the cervical spine called a syrinx. This can cause arm/hand symptoms with some numbness in a shawl pattern across the shoulder area. An MRI through your cervical spine should show this fluid collection if it is there. It can be followed after the chiari is decompressed usually resolving by itself. ...Read more
I have chiari malformation and we found this on an mri. Another mri for the spine and no fluid was blocked. My symptom get worse. Do I need surgery?
Neurosurgery always: Sounds scary. In truth, current minimally invasive techniques have remarkably low risk in the hands of pediatric and adult neurosurgeons. And that's who you need to ask, because the decision is not based on the size, or length, of the Chiari malformation, it's based on symptoms that interfere with a person's daily functioning. Review your MRI's with the neurosurgeon at your first consult. ...Read more
I want to speak to a dr regarding crainocervical instability and chiari malformation. I have a 2014 and 2016 mri. I live in the UK.
If I have chiari malformation 1 and my spinal Mri came up negative do I still need surgery? I have symptoms just nothing wrong with my spinal fluid
Neurological: Symptoms guide the decision that surgery is needed. Pressure from the cerebellum on the spinal cord or lower brainstem can cause neurological signs & symptoms. Read all the pages on www. Mayoclinic. Org/diseases-conditions/chiari-malformation/basics/definition/con-20031115. Seek a 2nd pediatric neurosurgical opinion if you are hesitant. ...Read more
When symptomatic: When symptomatic or when mild symptoms being followed change. ...Read more
What does it mean when my MRI results say that my cerebellar tonsils are seen low lying 4.2mm below, suggesting chiari malformation?
Chiari malformation: What you're describing is a typical finding for a chiari type 1 malformation. Chiari malformation is basically when part of the brain (cerebellum) sits below the base of the skull. This may cause headaches, weakness, trouble swallowing/speaking, numbness of the arms....Many different symptoms are possible. It also can be asymptomatic. Get a neurological or neurosurgical evaluation. ...Read more
Does "some what low lying cerebellar tonsils" necessarily mean chiari malformation? That was the impression on my mri. Should I be worried?
My granddaughter was diagnosed with chiari malformation. The MRI shows slight reversal of the cervical lordosis and minimal anterolistesus of c3?
I have been diagnosed with a middle cranial fossa meningomia and chiari malformation my MRI also shows empty sella morphology. Should I be concerned?
Why ask here?: Presumably in Georgia you can't just wander into an MRI facility and make an impulse purchase. The MRI isn't the patient; you are. It doesn't sound like anything serious, but I'm not your doctor. The ordering doc is responsible for interpreting the results or if they can't, to send you to someone else who can. You have a right to an explanation in terms you can understand. Meanwhile, don't panic. ...Read more
Can white matter on brain MRI be some kind of connection with my chiari malformation? Can it be spinal fluid build up?
Come again?: Brain consists of gray matter (neurons' cell bodies) & white matter (connecting fiber tracts). Chiari malformation has to do with position of cerebellum at base of brain. These 2 things aren't related at all. Finally, can WHAT be spinal-fluid buildup? You'll understand much better if you educate yourself about brain anatomy. There are good sources for laypeople. It's NOT beyond your ability. ...Read more
I have chiari malformation type 1. Mri shows loss of cervical lordosis and disc herniation at c5-c6. Is this connected?
No: Disk problems are not associated with the chari 1 malformation. ...Read more
Would a chiari malformation show up on a brain mri? Had 3 Mris in the past 2 yrs and they haven't seen one but lots of pain and pressure nape of neck
Evaluate neck: Do NOT understand repetitive focus on Chiari malformation, even with history of connective tissue disorder. However, appears you do NOT have it. See a good osteopathic or rehab doctor, and uncover pain generator in neck, and treat underlying problem. Many co-morbidities can be associated with Ehlers-Danlos. ...Read more
Is it possible to have "slightly low lying cerebellar tonsils" without it being chiari malformation? That was a finding on MRI but doc says no chiari
Yes,: I suppose so. Chiari malformations have specific findings. "Slightly low lying cerebellar tonsils" is a somewhat nebulous, nonspecific subjective description. It probably means that the tonsillar tip is below the foramen magnum but within the range of normal variation, but if you are concerned, talk to your doc about it. ...Read more
Does a standard brain CT or MRI go down far enough to be able to see a chiari malformation if there was one?
Went for MRI last year for tinnitus and found out I have arachnoid cyst and chiari malformation recently have worsening tinnitus blurry vision, why?
Blurred vision &,: Less commonly, tinnitus, can be symptoms of a Chiari Type I from the cerebellar tonsils' causing pressure on the brainstem &/or spinal cord or blocking flow of CSF. Arachnoid cysts may have no symptoms or may cause pressure on the parts of the brain they overlie, especially if there is an increase in size of the fluid-filled sac. Thorough medical & neurological re-evaluations are warranted. ...Read more
Just diagnosed with chiari malformation 1 after mri. Is surgery always necessary? I have no symptoms other than posttussive headaches.
Basic answer: The cerebellum is the rearmost part of the brain structures as it transitions into the spinal cord holding all the nerve tracts. This part of the brain is supposed to stop at the base of the skull, but in some people part of the cerebellum is positioned below the skull, extending between the cord & the upper vertebrae. The Chiari malformation is a broad label covering this defect. ...Read more
Head/ Cervical MRI: Chiari malformation is best diagnosed with a head MRI without contrast to assess for the abnormal tonsil position and determine whether hydrocephalus, or water on the brain, is present also. A cervical MRI without contrast can assess for a problem called a syrinx, or a fluid cavity in the center of the spinal cord. A lumbar MRI without contrast can also exclude a tethered cord causing numb legs. ...Read more
Chiari malformation: The most common chiari malformation is the type 1. There is a situation where two "tongues" of tissues called the cerebellar tonsils leave their normal anatomical position and herniated down through a hole at the base of the skull called the foramen magnum and can lead to compression of the brain stem. ...Read more
