Abstract/OtherAbstract:
A 56-year-old man presented to the outpatient clinic with a 3-year history of itch within the innervation territory of C-6 of the left arm. Sudden neck movements induced intermittent paresthesias in the same dermatome. No dermatological diseases, allergies, or trauma to the affected extremity or the spine or a history of familial pruritus were reported. Neurological physical examination and electromyography revealed normal findings. Quantitative sensory testing demonstrated selective C-fiber dysfunction at C6-8 on the left, and cervical MR imaging revealed multilevel degenerative cervical spine pathology with neuroforaminal stenoses. Brachioradial neuropathic pruritus caused by cervical neuroforaminal stenosis was the final diagnosis. Treatment consisted of 2 cervical epidural steroid applications that resulted in clinical disappearance of the itch and improvement in C-fiber function on quantitative sensory testing.
