Brain Metastasis in a Case of Osteosarcoma

Abstract

Introduction: Sarcomas are responsible for about 3% of brain metastases and brain metastases are found in 1-8% of patients of sarcoma patients. One of the most prevalent malignant bone tumors in adolescents and children is osteosarcoma, which only rarely spreads to the central nervous system. We report here a rare case of an 8-year-old boy with brain metastasis from osteosarcoma of the foot. Case Report: An 8-year-old male presented with osteosarcoma of the foot and brain because of metastasis from the primary tumor. After diagnosis by CT scan and PET scan, the patient underwent occipital- parietal craniotomy with gross total excision of the skull along with pirogoff’s amputation for the foot. On histopathological examination, the diagnosis of osteosarcoma was confirmed and patient was started on chemotherapy. Conclusion: Brain metastasis with osteosarcoma is a rare condition. However, aggressive craniotomy and excision of the primary tumor with timely chemotherapy can result in long term survival of patient. However, a proper protocol must be followed to achieve this.
