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.
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.
