Neurofibromatosis: an unusual cause of cervical myopathy.

Generalized neurofibromatosis (NF) is characterized by café au lait spots, deformity of the skeleton and tumors involving the skin as well as spinal, peripheral and cranial nerves. The spine is that part of the skeleton most commonly affected in NF, although involvement of the cervical spine in NF has only rarely been reported. The majority of neurofibromas involving spinal nerves are asymptomatic or present with symptoms consistent with nerve root involvement.
