A lumbar puncture is done to: Find a cause for symptoms possibly caused by an infection (such as meningitis), inflammation, cancer, or bleeding in the area around the brain or spinal cord (such as subarachnoid hemorrhage).
What is chorea? Chorea refers to involuntary movements characterized by their random, brief, and non-rhythmic character. They are often described as seeming to âflowâ from one body part to another unpredictably, though they can also be confined to a single area of the body (such as the mouth area or hands).
Sydenham chorea can occur in rheumatic fever and may be the first symptom of it. A tumor or an infarct in the striatum (caudate or putamen) can cause acute unilateral chorea (hemichorea). Sydenham chorea and chorea due to infarcts of the caudate nucleus often lessen over time without treatment.
