ObjectiveThis study presents the results of a systematic literature review conducted to determine most up-to-date information on the natural outcome of cervical spondylotic myelopathy (CSM) and the most reliable diagnostic techniques. MethodsA literature search was performed for articles published during the last 10 years. ResultsThe natural course of patients with cervical stenosis and signs of myelopathy is quite variable. In patients with no symptoms, but significant stenosis, the risk of developing myelopathy with cervical stenosis is approximately 3% per year. Myelopathic signs are useful for the clinical diagnosis of CSM. However, they are not highly sensitive and may be absent in approximately one-fifth of patients with myelopathy. The electrophysiological tests to be used in CSM patients are motor evoked potential (MEP), spinal cord evoked potential, somatosensory evoked potential, and electromyography (EMG). The differential diagnosis of CSM from other neurological conditions can be accomplished by those tests. MEP and EMG monitoring are useful to reduce C5 root palsy during CSM surgery. Notable spinal cord T2 hyperintensity on cervical magnetic resonance imaging (MRI) is correlated with a worse outcome, whereas lighter signal changes may predict better outcomes. T1 hypointensity should be considered a sign of more advanced disease. ConclusionThe natural course of CSM is quite variable. Signal changes on MRI and some electrophysiological tests are valuable adjuncts to diagnosis.

Our study shows that software version is comparable to the paper version. It may prove to be a useful tool for epidemiological studies and patient follow-up over longer period.

Neurogenic tumours of the paraspinal space can occur in all age groups. It is common in adult population and relatively rare in elderly group. Usually they are benign, but in children, arising from the autonomic system, tends to be malignant in nature. Usually in adults, they arise from peripheral nerve sheath and are labelled as schwannomas. For a given tumour, determination of a correct surgical approach is mandatory to achieve a successful surgical outcome. Several factors like tumour size, histology, involvement of the bony spinal canal, etc. are some of the deciding factors for a correct surgical approach. Since many such tumours are benign, total excision is possible with a correct surgical approach. If the tumour involves the integrity of the spine then additionally a stabilization procedure may have to be carried out. Unfortunately, there are still no guidelines regarding the choice of surgical approach for the excision of such tumors. Presented here is a series of five patients managed by us over a period of 10 years. Four patients were adults and one female child was three years old. Four patients were operated upon successfully and the fifth one is waiting for surgery.
