I have several symptoms and they seem to be increasing daily. I am currently waiting to see a neurosurgeon. I have a brain mri that the results indicated chiari malformation. I would like to know the size of the chiari malformation.
Also I have an mri of thoracic spine that I was wondering about the diagnosis of hemangioma…can you confirm. I wondered if there was something more going on in that area.
Just a few of my symptoms…fingers numb on right hand, difficulty with fine motor skills, muscle fatigue when walking short distances, memory loss, bladder control issues, constant wrist pain, constant shoulder pain, visual problems, dizzyness, fall a lot, facial numbness, headaches, etc. Negative for carpal tunnel. Negative for pinched nerves…so far only diagnosis is chiari malformation. Thank you for opinion on any of this. I can not find a way to attach files. Is there a way to email them to you?Donald Corenman, MD, DCModeratorJuly 30, 2011 at 1:20 amPost count: 8500
Arnold Chirari malformation is a problem with the brain stem at the base of the skull. The cerebellum is the part of the brain at the lowest aspect of the skull and has two paired structures, the cerebellar tonsils that are right above the foramen magnum- the hole at the base of the skull that the spinal cord exits from and arteries enter to supply the base of the brain.
In a case that these tonsils descend or are “pushed” into the foramen magnum to crowd the spinal cord, this is call an Arnold Chirai type 1 malformation. This may or may not be symptomatic. The type 2 disorder has more of the brain stem that is pushed down to crowd out the spinal cord and is more associated with symptoms.
Symptoms include balance problems, arm and leg weakness, paresthesias (pins and needles) and numbness, swallowing, tinnitis (ringing in the ears), nausea, vomiting, headache and base of the skull pain. A condition called syringomyelia can occur which is a collection of fluid in the spinal cord- associated with the type 2 problems.
The “size” of the Arnold Chiari disorder depends upon how “congested” and deformed the brain stem is and what signs and symptoms are associated.
The “hemangioma” found in the thoracic spine may or may not be a problem. Benign hemangiomas are quite commonly seen on an MRI of the vertebral body and generally do not cause problems but there are rare hemangiomas that can be troublemakers. You need a good consultation to determine the significance of both.
