Malignant solitary fibrous tumor of the lumbar spinal root
mimicking schwannoma: a case report.
In our patient, we recorded chronic neurogenic MUP changes in the muscles innervated by left L5 spinal root
in needle EMG as reported in the literature.
As the myelination progresses from the spinal root
toward the periphery, the value of proximal conduction velocity would be higher than distal segment in developing nerve trunk.
All patients with clinical signs of spinal root
deficit also underwent pre- and postoperative neurophysiological studies (see Neurophysiologic Evaluation).
It is well known that patients with primary headaches often report pain not only involving the frontal head innervated by the first (ophthalmic) division of the trigeminal nerve, but also involving the occipital region innervated by the greater occipital nerve (GON), a branch of the C2 spinal root

mimics metastatic melanoma: a potential pitfall for misdiagnosis," International Journal of Clinical and Experimental Pathology, vol.
Neurofibromatosis type 1 (NF1) is an inherited disorder characterized by formation of tumors (neurofibromas) involving nerve tissues in skin, subcutaneous tissues, cranial nerves, and spinal root
Localization helps in diagnosis: fasciculations can be generalised, in metabolic-toxic conditions, the benign fasciculation syndrome and degenerative disorders of anterior horn of spinal cord, as amyotrophic lateral sclerosis; segmental, as in syringomyelia; or focal, affecting the muscles controlled by a nerve or spinal root
. When fasciculations are in a distribution that cannot be explained by plexus, root or nerve lesion amyotrophic lateral sclerosis (ALS) must be ruled out as soon as possible.
(4, 5) We noted during dissection that manual traction applied to the RCPma caused movement of the spinal root
within several levels.
Lateral spinal root
stenosis is a common condition occurring in 8 to 11% of surgical cases of lumbar degenerative disease .
One spinal root
sends information to the muscle and one spinal root
transmits sensation from the muscle to the spinal cord.
There were 1/20 patients that had bilateral findings, while only 2/1 reported having bilateral symptoms that supports SEPs having a higher sensitivity in detecting spinal root
compression secondary to spinal stenosis.
