CASE REPORT Idiopathic Carpal Tunnel Syndrome Presenting with Raynaud’s Phenomenon: Neurophysiological Evaluation

Carpal tunnel syndrome and Raynaud’s phenomena are common diseases and coexist in some patients while in others Raynaud’s phenomenon may be a clinical feature of carpal tunnel syndrome. I describe an interesting case with Raynaud’s phenomenon as a predominant presenting clinical feature due to an underlying mild carpal tunnel syndrome with preferential involvement of the autonomic fibers. Nocturnal wrist splinting, a common treatment for carpal tunnel syndrome, resulted in marked improvement in the symptoms.
