The document discusses spinal tumors, including: - Types are extradural, intradural extramedullary, and intramedullary tumors. Extradural tumors most often originate from metastases and present with compression and pain. - Intradural extramedullary tumors include meningiomas, which appear attached to the dura and cause slow, progressive neurological deficits. Ependymomas are the most common intramedullary tumor. - Clinical presentation is usually back pain and neurological deficits depending on location and severity of compression. Diagnosis involves imaging like MRI and treatment depends on tumor type and involvement.
