- What is Arnold-Chiari Condition?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: Would you please give people some information on Arnold-Chiari?
- I'm 43 and just found out a week ago. I did have a bone removed 3 years ago
- that was pinching my spinal cord. The doctors say they want to wait before
- they do more surgery. Can you explain this condition for me and what my
- outcome will be?
-
- ------------------------------------------------------------------------------
-
- ANSWER: The condition which bears the name of two German physicians who first
- described it back in the 1890's results from a congenital deformity of the
- occipital bone, which forms the back of the skull, and the upper end of the
- spine. Because the occipital bone is flattened, a portion of the brain may
- move downward through the large hole in this bone (called the foramen magnum)
- and come to rest in the neck portion of the spinal canal. This can provoke a
- wide variety of symptoms, including headaches, vomiting, visual troubles
- including double vision dizziness and sometimes weakness of the arms and legs.
- Although these problems may develop during childhood, the symptoms start most
- often in adults between the ages of 30 and 60. It affects both sexes with
- about equal frequency, and the reason for the changes in these bones is still
- unknown. Physicians may use a number of techniques to discover the extent of
- the condition, including myelography. This technique uses x-rays and a
- radio-opaque substance (sometimes misnamed a "dye") injected into the space in
- the spinal cord to obtain a picture of the location of the brain tissue. CT
- scans have also proved useful. The need for additional surgery will depend
- upon the findings of these tests and your own condition. If the first
- operation was sufficient to remove your symptoms, more surgery may not be
- necessary, and waiting is just fine. It is hard for me to predict an outcome,
- for this varies greatly with the individual and the extent of the changes in
- your structures; but a frank and open discussion with your physicians, who
- seem to have the situation in hand, should provide you with their opinion. I
- would hope they could give you an optimistic report, for this condition can be
- helped.
