ABSTRACT

Acroparesthesias of the arms are characterized by feelings of pins and needles, tingling, numbness, and pinching that can affect all fingers or be localized to only some of them. Acroparesthesias can be unilateral or bilateral. Depending on their topography and character, one can distinguish:

• Global acroparesthesias, affecting the whole hand and occurring usually during the night

• Acroparesthesias with radicular topography • Acroparesthesias with entrapment topography

They may originate from lesions in the spinal cord (syringomyelia) or the cerebrum. Multiple causes can provoke a feeling of numbness, of a swollen hand, or of a dead finger that characterizes this syndrome. The leading pathologic cause of this syndrome by far is carpal tunnel syndrome.
