Abstract We report our experiences of four cases with meningeal hemangiopericytoma treated with surgery and postoperative radiotherapy and survey the literature to elucidate the efficacy of radiotherapy. Patients were treated with surgical resection and 46-52 Gy postoperative radiotherapy. Three patients had local control for 30, 54 and 138 months, respectively and one patient had local recurrence after 49 months. Distant metastases were observed in two patients; one had multiple bone, liver and lung metastases and the other multiple bone and brain metastases. For bone and brain metastases, better tumor control was obtained with palliative radiotherapy and stereotactic radiotherapy. Literature analyses demonstrated that surgery and postoperative radiotherapy of 50 Gy or more resulted in significantly better local control than surgery alone (p = 0.02). Stereotactic radiosurgery was effective for intracranial recurrence or metastasis, especially when the tumor volume was <8 cm(3) and >15 Gy at the 50\% isodose line was used. Radiotherapy for bone metastases was also effective for palliation.
