Dural based sarcoma is a rare aggressive neoplasm arising from the multipotent primitive mesenchymal stem cells of the dura. A 61-year-old male patient presented with complaints of loss of visual acuity in his right eye for 1 week. Neuroimaging revealed a tumour located at the right temporal lobe. The mass was dural-based. Three years ago dural based lesion was seen. In that period radiological diagnosis was meningioma. Within three years, the lesion has grown and radiologically presumed meningioma view has been disappeared. After surgical resection of the mass pathological diagnosis of primary dural based sarcoma was made. As in soft tissue sarcomas, diagnosis is mainly based on light microscopy, while immunohistochemistry can improve accuracy of diagnosis. In this article we would like to highlight two things: one is dural sarcoma and meningioma cannot be distinguished radiologically, and the other is the patient's three-year history
