There is a wide range of spinal tumors that can manifest in the intradural lumbar spine, including ependymoma, astrocytoma, myxopapillary ependymoma, schwannoma, neurofibroma, malignant nerve sheath tumor, paraganglioma, hemangioblastoma, metastatic disease, and meningioma. Surgical considerations for these lesions include the use of electrophysiology, standard open approaches, emerging minimally invasive approaches, microscopic techniques, and specific surgical nuances based on the anatomical relation between the tumor and the spinal cord or filum terminale. Understanding these principles and techniques of treating these intradural lumbar spinal tumors will maximize outcomes.
