introduction spinal tumours may be classified in three groups: 1) extradural, 2) intradural extramedullary and 3) intramedullary spinal cord tumours. intradural extramedullary tumours arise from the leptomeninges or nerve roots and include schwannomas. a schwannoma is usually a firm grey-whitish tumour growing near a nerve trunk or ramus. it can be separated from the nerve without damaging neur...

Spinal cord tumours account for about 15% of central nervous system neoplasms. Intramedullary tumours arise within the substance of the spinal cord, whereas extramedullary tumours are extrinsic to the cord. About two thirds of spinal cord tumors in adults are extramedullary in location, among which nerve sheath tumors, meningiomas and Filum terminale ependymomas account for the most. Metastatic...

Teratomas in the spinal cord are rare. We report a case in a 54-year-old man. CT scans revealed tumours of different densities within the spinal canal; this heterogeneity may help to differentiate teratoma from other spinal cord tumours. After resection of the tumours under microscopy, the result was excellent. Histological examination showed a variety of tissues, including elements of all thre...

Intraspinal and spinal cord tumours are quite rare in childhood. Most authors reporting cases of tumours found within the spinal canal use the term 'spinal cord tumour' in a broad sense without regard to whether they are spinal cord tumours proper or of extradural origin. In this paper we refer to an 'intraspinal' neuroblastoma in a newborn infant, and wish to emphasize that though it is intras...

OBJECTIVE Currently, the standard practice to treat intradural spinal tumours involves microsurgical resection of the lesions. It is essential to be able to locate the lesion precisely to reduce the risk of neurological morbidity. The purpose of this study was to evaluate intraoperative ultrasonography (IOUS) in visualizing intradural spinal tumours, and assess its potential to improve surgical...

Most surgery is designed to relieve compression of the spinal cord or spinal nerve roots. Reduction in the bore of the vertebral spinal or root canals (spinal stenosis) can occur in many conditions, and some patients have congenitally narrow canals. Osteophytic projections at the intervertebral joints (cervical spondylosis) are the commonest problem. Tumours, infection, trauma, disc protrusions...

Of 214 children with malignant tumours admitted in the Children’s Hospital between 1987 to 1991, six (2.8%) had spinal cord compression. The diagnosis and levels of spinal cord compression were substantiated by Omnipaque myelography in all patients. Location of the lesion was confirmed by laminectomy. Biopsy and histopathology were done to confirm the tumour types. Spine roentgenography as well...

Neurofibromatosis 1 (NF1) is an autosomal dominant disorder associated with a variety of benign and malignant lesions such as café au lait spots, neurofibromas, phaeochromocytomas, pilocytic astrocytomas, and malignant peripheral nerve sheath tumours. With an incidence of 1 in 4000, NF1 is caused by genetic alterations of the NF1 gene located on 17q11.2. Consisting of 60 exons, the NF1 gene is ...

In India all types of nervous disease exist, but very few spinal tumours are reported. This does not mean that the incidence of spinal tumours in this country is a rare phenomenon. The diagnosis of a spinal tumour is made by the clinical symptoms of (1) the root cycle usually unilateral; (2) the Brown-Sequard syndrome; (3) the compression paraplegia, and by special clinical tests such as lumbar...
