Twenty Year and Still Isolated Form of Restless Arm with Hypometabolism of Brain in Caudate Bilaterally

摘要

We reported a patient with restless arm but without any other extremity involvement during 20 year period. There was hypometabolism of brain in caudate bilaterally. Interestingly, the restlessness had not progressed to involve other hand or his legs during this long time period. Only restless arm syndrome (RAS) is very rare. In describing the patient, we hope to raise awareness about RAS and avoid misdiagnoses and inappropriate investigations.
