| Summary: | Although brain metastases from bone and soft tissue sarcoma are uncommon, advances in sarcoma treatment have led to an increasing incidence of them. We present a 23-year-old male with a history of metastatic femoral osteosarcoma, who presented with headache and unsteady gait and was diagnosed with a cerebellar metastasis. CT scan revealed a mass in the left cerebellar parenchyma with large intralesional central calcification and perilesional edema. Corticosteroid treatment led to neurological symptoms resolution, with a rapid tapering. The patient had also lung metastases and we opted to administer systemic treatment with the tyrosine kinase inhibitor cabozantinib. Given the relative radioresistance of osteosarcomas, the patient did not receive radiation therapy.
