RESUMO
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.
RESUMO
Spinal giant cell tumor (GCT) and aneurysmal bone cyst (ABC) are infrequent neoplasms of bone. Thirty percent of ABCs are secondary to tumors, such as GCT. We report a rare case of a pediatric cervical spine secondary ABC to GCT that had to be multimodally managed through anterior and posterior surgical approach, embolization, and denosumab treatment leading to a stabilization of the remnant. The case shows the importance of therapeutic strategy decision that depends on the patient and the lesion.
