<b><i>Introduction:</i></b> Intraspinal epidermoid cysts are congenital or acquired in origin; whereas intraspinal neurenteric cysts (NECs) are of congenital origin. Their individual association with spinal dysraphism and vertebral segmentation anomalies is very well known. <b><i>Case presentation:</i></b> We hereby report a case of concurrent intradural extramedullary epidermoid and NEC at adjacent vertebral levels in a spinal dysraphism child, not reported in English Literature till now. <b><i>Conclusion:</i></b> Multiple spinal lesions related to any/all of the 3 germ layers can coexist at same or adjacent vertebral levels in the same patient and surgical planning shown to be done accordingly.

Intradural Extramedullary

Ependymomas are common spinal lesions, with the vast majority arising in an intramedullary location. Several cases have been described in the literature of ependymomas in an intradural, extramedullary location. The authors present a case of a 56-year-old female who presented with several weeks of lower back pain and weakness. MRI revealed an intradural, extramedullary enhancing mass at L1-L2. The mass was successfully resected surgically. Pathologic evaluation revealed a low grade glioma with components of both ependymoma and pilocytic astrocytoma with MUTYH G382D mutation. Extramedullary ependymomas are very rare tumors. To the authors’ knowledge, this is the first case of ependymoma/astrocytoma collision tumors described in an extramedullary location.

Considerable Experience

Although there has been considerable experience with anterior approaches to ventral intradural, extramedullary, and pial-based spinal lesions, there is no information in the literature regarding the safety and feasibility of the resection of an intramedullary tumor via an anterior approach. The authors report on the gross-total resection of an intramedullary cervical pilocytic astrocytoma via a C-7 corpectomy and anterior myelotomy. The surgery proceeded without complication, and postoperatively the patient maintained the preoperative deficit of mild unilateral hand weakness but had no sensory deficits. Follow-up MR imaging at 6 months showed gross-total macroscopic resection. Selected intramedullary tumors can be safely removed via an anterior approach. This approach avoids the typical sensory dysfunction associated with posterior midline myelotomy.

Intradural Extramedullary Tumour

Tumour excision and laminoplasty are commonly performed as surgical treatment of extra vertebral extension of cervical schwannoma. It is worth knowing that the conventional technique of multilevel laminectomy may hinder younger patients in the long-term. This article reports a 30-year old man with an intradural-extramedullary tumour which extended from C4 to T1 that underwent modified laminoplasty.  This modified technique is preferable in maintaining the anteroposterior diameter of spinal canal as well as reducing the displacement of guttered laminae

Methods Of Treatment

Epidemiological studies show an increase in the number of people with cancer. Bone metastases are a frequent manifestation of generalized cancer, because it is in malignant tumors of the spine more often than other bones of the skeleton becomes a target for metastasis. The article describes in detail the methods of diagnosis of spinal lesions in cancer pathology. Particular attention is paid to the scales reflecting the severity of the patient’s condition, the degree of spinal cord damage, the severity of pain in metastasis to the spine, the prognosis of survival in oncovertebrology and evaluation of the stability of the spine in metastatic lesions. Further, the paper presents non-radical (decompression, vertebroplasty) and radical (spondylectomy, corporectomy) surgical methods of treatment
