Investigation of spinal pathology in notalgia paresthetica.

A possible association of spinal pathology with notalgia paresthetica (NP) was investigated through clinical and radiographic evaluation. Forty-three NP patients underwent dermatologic and orthopedic examination accompanied by radiography of the spine. Sixty-one lesions in 43 patients were evaluated. In 34 patients, various vertebral pathologies were observed radiographically by a blinded investigator, and in 28 of these cases these changes were most prominent in the vertebrae which corresponded to a lesional dermatome. Thirty-seven lesions were accompanied by spinal changes decided to be relevant (60.7%). The striking correlation of NP localization with spinal pathology suggests that spinal nerve impingement may contribute to the pathogenesis of this entity.
