Doctor insights on:
Incidental on MRI: Chiari type I is an incidental finding on an MRI that shows low lying tonsils of the cerebellum. A line can be drawn on the film and the measurement in millimeters of how low the tonsils lie. If just a few mm, it is considered borderline. Most cases are just incidental and are not clinically relevant. ...Read more
If I have borderline chiari 1 since my symptoms are still very severe can I still be a canidate for surgery?
Need a consult: Best to discuss with a board certified neuro surgeon. Hope that helps. ...Read more
I have had 3 mri's this past year due a colloid cyst. I had my 3 month post op mri, it showed borderline Chiari l malf. Why didn't it show before?
Depends on reader: It probably did but since you're saying that it was called "borderline" by one radiologist that means that it is so close either being called Chiari or NOT BEING called Chiari that who ever the last person was who read it may have chose not make ANY call compared to the current reader who chose to read it using MAXIMUM WAFFLING CAPACITY!

Migraine history MRA/MRI results: right A1 anterior cerebral artery is hypoplastic. Right P1 posterior cerebral artery is markedly hypoplastic. Low lying cerebellar tonsils, no chiari. Borderline high riding left jugular bulb. What's the significance?
High potassium, platelets, wbc, acth test low. Fever still, muscle, joint pain, dizziness, etc, chiari too. Borderline addison's.Do I have it? Hemoc poss. Y
Not likely,,,: Due to your low acth, you might have secondary adrenal insufficiency which can give many of the same symptoms, like dizziness and muscle pain. You also could have an infection as seen with your high wbc. It would be smart to see your doctor and get an acth stimulation test to see for sure if your adrenals work right. ...Read more
Arnold-Chiari: A-c is a malformation of the brain consisting of a downward displacement of the cerebellar tonsils through the opening at the base of the skull, sometimes causing non-communicating hydrocephalus as a result of obstruction of cerebrospinal fluid (CSF) outflow. It can cause headaches, fatigue, facial muscle weakness, difficulty swallowing, dizziness, nausea, incoordination, and paralysis. ...Read more
Chiari type II (2)?: Chiari malformations develop due to a decreased size in the back of the skull. Because there is not enough space for the brain to develop, a part of the brain called the cerebellar tonsils get pushed through through the hole where the spinal cord attaches to the brain. This results in increased pressure and development of "cysts" in the spinal cord. Chiari ii has additional brain&cord changes. ...Read more
NO: Chiari 1 is an incidental finding of low lying cerebellar tonsils. This finding is of minimal clinical significance unless a degree of pressure causes some specific symptoms. In occasional cases decompressive surgery can relieve some of these symptoms. In some cases the surgery just causes more discomfort. The findings of the chiari 1 do not change with surgery. ...Read more
Three types: Chiari malformations come in three types (i, ii, and iii). Type I is, by far, the most common. There is a hole at the bottom of the skull where the spinal cord exits (the foramen magnum). If the back part of the skull is not large enough to house the cerebellum, the lower portion of the cerebellum can push through the foramen magnum and into the spinal canal - this is a chiari I malformation. ...Read more
Depends on symptoms:
Most patients with chiari I malformation have no symptoms, and don't need surgery. Findings that would require surgery include cranial nerve dysfunction, swallowing problems, arm or leg weakness, numbness, syrinx formation in the spinal cord. In this group of patients, surgery can help.
You should be thoroughly evaluated by a neurosurgeon to see if you require treatment or just observation. ...Read more
It can be: Hydromyelia and/or syringomyelia can develop for many reasons, including trauma, tumors, developmental abnormalities and sometimes with no clear cause. Chiari malformations are commonly associated with these conditions, but not exclusively. ...Read more

Complex: The imaging part is straightforward - you see herniation of the cerebellar tonsils on an MRI scan. The symptoms can be more difficult to pinpoint - these include headaches, fatigue, muscle weakness in the head and face, difficulty swallowing, dizziness, nausea, impaired coordination, and, in severe cases, paralysis. ...Read more

Chiari Malformation: It is a congenital disorder when the cerebellum, the part of the brain which controls balance, is below the foramen magnum (which is a opening at the base of the skull). Symptoms of a chiari malformation could be balance issues, neck pain, numbness to arms, and headaches. If symptoms are severe, a patient can seek consultation with a neurosurgeon to discuss if they could benefit from surgery ...Read more
Many do not: The finding of a type one chiari malformation is often an incidental finding on MRI of no clinical significance. These do not need surgery. Surgery for the malformation is quite complex and must be considered very carefully. There are significant risks to the surgery that must outweigh the risks of not doing surgery. Second, third, and fourth opinions may be appropriate. ...Read more
Extent of herniation: It is the downward displacement of the cerebellum, specifically a region called the "tonsils", through the foramen magnum. There are actually 4 types. Type one is only tonsillar herniation, that is mild; type ii shows more herniation, to include a middle portion of the cerebellum. This type is often associated with an myelomeningocele (herniation of lining of the brain). ...Read more
Brain issues: If you have symptoms or reason to believe you have any brain malformation please see your doctor. He/she will assess the situation and order the proper tests which is the way to rule out your concern or offer proper treatment. Peace and good health. ...Read more
