Introduction: Intradural extramedullary cervical lesions usually cause pain or neurological deficit secondary to neural compression. Traditional treatment of these tumors includes standard fashion cut incision, open laminectomy and some cases fusion.

Methods: We present four patients (one woman and tree man) with symptoms include radicular pain and/ or neurological deficit, due intradural-extramedullary cervical lesion. All the patients underwent total resection with minimally invasive uniportal technique using a tree blade MAXCESS retractor system (Nuvasive, Inc). We measured a VAS, Nurick scales preop and with follow up of 6 weeks, 3,6 and 12 months pop. Surgical time, blood loss and time to discharge. All the patients was underwent control MRI postoperatively.

Results: Histologically report: One patient neurenteric cyst, two patients: neurocisticercosis and the last: epidermoid cyst. The VAS and Nurick scales was decreased over the time line. The surgical time was 140 minutes mean, blood loss 30cc mean, All the patients was discharged 47hours mean and return to daily activities 10 days mean.

Conclusions: Intradural-extramedullary lesions can be safely and effectively treated with minimally invasive techniques. Potential reduction in blood loss, hospitalization ,disruption to local tissues and return to daily activities suggest that, this technique may present an alternative to traditional open resection.

Patient Care: This minimally invasive technique Improve the symptoms with less blood lose and allow a short hospitalization and return to daily activities.

Learning Objectives: By the conclusion of this session, participants should be able to: 1) Describe the importance to know the unusual intradural-extramedullary lesions of the cervical spine- 2) Discuss, in small groups the importance of minimally invasive techniques to approach this lesions. 3) Identify an effective treatment such as minimally invasive options to achieve good results and quickly recovery.
