Abstract:
Medulloblastoma is one of the most undifferentiated primitive neuroectodermal tumors and represents about 30% of all posterior fossa tumors in children. Disseminated medulloblastoma, mainly involving cerebral surfaces, ventricles and the subarachnoid space can, in 50% of patients, be identified on intial imaging studies. One thirdof these lesions metastasize to an extracranial site, primarily to bone. Osseous metastases, which occur mainly after craniectomy are typically lytic, but osteoblastic lesions also may occur. We experienced the case of a 14year-old female patient with multiple bone metastases of medulloblastoma after craniectomy. Bone metastaticlesions were present in the right femur and thoracic spine and were osteoblastic or osteolytic
