July 1st 2007
A 32-year-old left-handed woman presented with a 4-week history of progressive left hand numbness, tingling, and clumsiness. Symptoms worsened until she found it difficult to write and perform fine motor tasks. She reported having no transient neurological symptoms in the past. Her medical history was significant only for Dengue fever acquired several years ago while on a visit to Southeast Asia. She was taking no medications, and a review of systems was noncontributory.
