Extradural tumors square measure principally metastases from primary cancers elsewhere (commonly breast, prostate and respiratory organ cancer). Intradural tumours will be classified as intramedullary (within the spinal parenchyma) or extramedullary (within the dura mater, however outside the spinal parenchyma). Extramedullary tumours square measure additional common than intramedullary tumours.The database annal and accepted cachet of 164 patients 21 years of age and adolescent in whom an IMSCT was resected were reviewed. A gross-total resection (> 95%) was accomplished in 76.8% of the surgical procedures. Subtotal resections (80–95%) were performed in 20.1%. The majority of patients (79.3%) had histologically low-grade lesions.
Common extramedullary tumours embody meningiomas, schwannomas, extramedullary ependymomas, haemangioblastomas, whereas intramedullary tumours embody astrocytomas and intramedullary ependymomas. The diagnosing of primary funiculus tumors is troublesome, chiefly because of their symptoms, that in early stages mimic additional common and benign chronic spinal diseases. tomography and bone scanning square measure used for diagnostic functions.
