Unusual location of myxopapillary ependymoma in the sacrum: Case report and review of the literature.

Myxopapillary ependymoma, a rare variant of ependymoma, commonly occurs in the conus medullaris or filum terminale. The rarity of these tumors can make their diagnosis and treatment challenging. This case report presents an atypical occurrence of myxopapillary ependymoma within the sacrum in a 68-year-old patient presented with a 3-month history of persistent left-sided low back pain radiating to the legs and fecal dysfunction. The patient underwent a sacral laminectomy and subtotal excision of the tumor, followed by adjuvant radiotherapy with favorable outcomes. This report highlights the significance of tailored approaches for unconventional tumor locations emphasizes the potential benefits of multimodal treatment strategies and provides insights from a comprehensive literature review on similar cases.
