SURG-30. SURGICAL MANAGEMENT OF A RARE SACROCOCCYGEAL MYXOPAPILLARY EPENDYMOMA OF THE GLUTEAL REGION: CASE ILLUSTRATION AND SYSTEMATIC LITERATURE REVIEW

Abstract Ependymomas are rare tumors originating from neuroepithelial cells lining the wall of ventricles or central canal spinal cord. While these mainly occur within nervous system (CNS), there occasional reports in children and young adult patients with a primary tumor occurrence outside CNS. sacrococcygeal region have been infrequently described literature no standard care established. We present case report review regarding this entity. A 24-year-old woman presented right gluteal pain worsened by sitting palpable soft tissue mass region. Magnetic resonance imaging revealed 3.7 cm cystic centered Histology myxopapillary ependymoma. The patient underwent an interdisciplinary neurosurgical orthopedic oncology en bloc resection ependymoma, which intraoperatively appeared to originate coccygeal nerve. Through our systematic review, we identified 38 studies describing 78 unique cases ependymoma occurring without extension into exact presentation ependymomas is variable. Given their location propensity for drainage, they frequently misdiagnosed as pilonidal cyst. Recurrence occured 16.7% described, typically 20 years. Rate metastasis was 20%. means management complete surgical including excision neighboring sacrum coccyx, when involved. Ultimately, demonstrate that may isolated attached nerve, frank CNS involvement. Furthermore, approach lesion appears represent effective treatment modality.
