Case presentation:We describe two patients with simultaneous presentation of meningioma with astrocytoma. A correct preoperative radiological diagnosis was made in both patients and their tumors were completely removed microscopically. Pathological examinations confirmed that one among them was meningioma and the other an anaplastic astrocytoma. We reviewed the studies carried out regarding meningioma associated with astrocytoma in China as well as in other countries. Conclusion:In the absence of phacomatosis or prior radiation therapy, the reason for the simultaneous occurrence of astrocytoma with meningioma is not clear, and these tumors could be merely a statistical coincidence. Careful preoperative radiological evaluation and surgical management is of great importance in these patients.展开更多
