Background:
Cerebellar medulloblastomas are the most common malignant tumors of the posterior fossa in childhood that frequently metastasize. Leptomeningeal dissemination and distant metastasis have been associated with medulloblastomas; however, intramedullary metastases are rare with very few case reports in the literature available.
Methods:
We present a case of a 3-year-old girl with a medulloblastoma who underwent surgical resection of spinal intramedullary metastases. Histopathology revealed the tumor to be an anaplastic medulloblastoma similar to the intracranial lesions. The patient subsequently underwent postoperative chemotherapy followed by radiotherapy.
Results:
Following the surgery and subsequent follow-up, the patient showed a good recovery without any new neurological dysfunction.
Conclusions:
Intramedullary metastasis of medulloblastoma remains a rare disease. Surgical resection could play a possible role in the management in addition to radiation and chemotherapy.
Insights
This study reports a rare case of intramedullary spinal cord metastasis from cerebellar medulloblastoma in a child. Surgical resection, chemotherapy, and radiotherapy led to a good recovery, highlighting surgical management
