Description
Summary:Brain metastases of a chondrosarcoma are extremely rare, and treatment remains controversial. A 54-year-old woman had undergone surgical treatment for a femoral chondrosarcoma and its lung metastases. She presented with visual disturbance and dizziness 22 months after the initial surgery; imaging studies of the brain revealed a metastatic tumor in the left parieto-occipital lobe. Surgical tumor resection was performed; however, only 2 months after gross total resection of the tumor, rapid tumor recurrence was observed. Surgical resection was performed again, followed by intensity-modulated radiation therapy. Three months later, another small brain lesion was detected in the right parietal lobe and was treated with gamma knife stereotactic radiosurgery. No recurrence has been reported 20 months after this radiosurgery for brain metastasis. Thus, surgical treatment combined with several adequate radiation therapy sessions may be a viable treatment strategy for brain metastases of chondrosarcomas.
