Abstract

Aims: To emphasize the diagnostic challenge of primary cervical medulloblastoma mimicking a nerve sheath tumor in pediatric patients. Case Report: An 8-year-old boy presented with posterior neck swelling and spastic quadriparesis. MRI revealed a well-defined intradural extramedullary cervical mass with "dumbbell" extension, radiologically resembling a schwannoma. Gross total resection was performed, yielding significant neurological recovery. Unexpectedly, histopathology confirmed medulloblastoma. Discussion: Primary spinal medulloblastomas are rare and can radiologically masquerade as benign tumors. Unlike drop metastases, they lack intracranial involvement. Management requires surgical decompression followed by craniospinal irradiation and chemotherapy. Conclusion: Medulloblastoma should be considered in the differential of pediatric spinal masses. Early recognition and multimodal management are critical for favorable outcomes.
