Single-Staged Multilevel Spondylectomy for En Bloc Resection of an Epithelioid Sarcoma With Intradural Extension in the Cervical Spine: Technical Case Report

BACKGROUND AND IMPORTANCE: Occurrence of spinal epithelioid sarcomas is rare, with few cases reported in the literature. Although wide local resection is the recommended treatment, this technique is challenging in the spine. CLINICAL PRESENTATION: The case of a 17-year-old male with a recurrent epithelioid sarcoma with intradural extension in the cervical spine is presented. Because of nerve root involvement, the patient presented with right upper extremity weakness. The patient underwent a posterior C1-C4 spondylectomy to achieve an en bloc resection, followed by reconstruction from the occiput to T4. The right vertebral artery and C1-C4 nerve roots were sacrificed because of tumor involvement. After 3 years of follow-up the patient is disease-free but has persistent right deltoid weakness. CONCLUSION: Cervical spondylectomy via a single-staged posterior approach is a challenging yet feasible procedure for the treatment of epithelioid sarcomas. To the best of the authors' knowledge, this is the first report of complete resection of an epithelioid sarcoma with intradural extension in the cervical spine. Although neurovascular structures may warrant sacrifice, this procedure may provide improved long-term prognosis.
