Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

What are the tests for arnold-chiari malformation?

What are the tests for arnold-chiari malformation?

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

Can there be some connection between cervical dystonia and arnold chiari malformation?

Yes there is: Not only the dystonias but also other movement disorders such as the dyskinesias. Chiari malformation is readily treatable with decompression and may have a positive impact on the level of disability associated with these movement disorders. Please have it evaluated. Good luck and well wishes. ...Read more

What to do if I have arnold chiari malformation 1 and now I also have lupus. I am very active, but will that end?

Close follow up!: Arnold Chiari 1 occurs when part of the brain (cerebellum) presses into the opening at the base of the skull. The future depends more on what what your Neuro exams show over time. Symptoms may be mild (such as headache when sneezing) or more significant (imbalance/weakness). In lupus, ~ 70% of people can do very well while on therapy. Close follow up with MD's = best Rx to maintain active life!! ...Read more
