In order to assess the current prognosis of HMP we reviewed our personal experience limited to the last decade (1986-1995): during this period 7 patients (4M, 3F) were treated by surgery alone or surgery combined with postoperative radiotherapy. In spite of meticulous attempts at radical resection, the tumors recurred in all but two cases with a mean interval of 85 months, and a total of 18 operations were performed (2.57\/patient; range 1-4). Massive intratumoral hemorrhage determined acute deterioration and required emergency surgery in two cases while in one patient diffuse visceral metastases were discovered at autopsy. Five patients are still alive at follow-up but only 2 of them are in good neurological conditions and without evidence of disease. These results are similar to those reported in other series. In view of our results we conclude that intracranial hemangiopericytomas still have a dismal prognosis. Advances in neuroimaging, neuroanesthesia, microneurosurgery and adjuvant therapy do not seem to have significantly affected the recurrence rate, quality of life and mortality.<\/jats:p>","DOI":"10.1177\/030089169708300516","type":"journal-article","created":{"date-parts":[[2018,4,16]],"date-time":"2018-04-16T12:24:05Z","timestamp":1523881445000},"page":"856-861","source":"Crossref","is-referenced-by-count":52,"title":["Recent Experience in the Management of Meningeal Hemangiopericytomas"],"prefix":"10.1177","volume":"83","author":[{"given":"Andrea","family":"Brunori","sequence":"first","affiliation":[{"name":"Department of Neurosciences \u201cG.M.
