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.
Abbreviation used in this paper: QST = quantitative sensory testing.
