Please tell me what does chiari malformation show up as on an mri?

Chiari Malformation. 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.

I don't have any symptoms, but an MRI shows a chiari malformation.  what does this mean?

Three types. An asymptomatic chiari malformation shows a low situated cerebellum, it is asymptomatic and referred to as type i. Types ii and iii show the same, but a progressively worsening impingement on the foramen magnum and the occurrence of cervical spine impingement-giving rise to neck and shoulder numbness.

I have been diagnosed with a middle cranial fossa meningomia and chiari malformation my MRI also shows empty sella morphology. Should I be concerned?

Not life threatening. Your doctors will likely monitor the meningioma as long as you are not having any severe headaches or other symptoms from it. They are usually not malignant. The Chiari can also cause headaches and other symptoms like vertigo, or numbness- surgery for that may be optional. Empty sella is common- be sure to have your thyroid function checked. Bottom line is none of this is life- threatening. Read more...
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...

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?

Usually stable. Chiari malformation can be minimal and asymptomatic throughout life, incidentally found on an MRI done for another reason, or it can be significant and require surgery. It usually remains stable in each individual. A well founded discussion can be found here: http://www.ninds.nih.gov/disorders/chiari/detail_chiari.htm#281473087. Read more...

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...
