Intramedullary lesions of the conus medullaris: differential diagnosis and surgical management

摘要: The medullary conus represents a distinct entity of the spinal cord regarding its anatomical, clinical and microsurgical features. An overview pathologic processes this region is provided. Epidemiological, neuroradiological characteristics neoplastic (glial tumors, non-glial metastasis, primary melanomas) non-neoplastic lesions (granulomatous lesions, abscess, parasitic infections, vascular, demyelinating dysembryogenetic lesions) are discussed. Main MR imaging used to differentiate from consist in pathological expansion, gadolinium-enhancement tumoural cyst formation. Management strategies differ substantially, depending on kind lesion. According suspected radical resection, biopsy or conservative treatments reasonable options. Intraoperative electrophysiological monitoring fundamental part surgical setting.
