Meningeal hemangiopericytoma (HP) has mostly been viewed as a variant of meningioma. There is more and more evidence, however, that HP constitutes a separate entity among tumors of the central nervous system. The data of intracranial and spinal HP of 17 of our patients and from a review of the literature is compared to meningioma and to peripheral HP. Meningeal and peripheral HP present with a similar sex ratio, age distribution, tendency to metastasize and are almost never multiple. This is fundamentally different from meningioma. Other data of meningeal HP like interval between first operation and manifestation of a recurrence or metastasis and survival time cannot be compared to peripheral HP due to its special location. Prognosis of meningeal HP is distinctly worse than of meningioma, placing HP between malignancy grade I and II as specified by WHO.
脑膜血管外皮细胞瘤（HP）大多被视为脑膜瘤的一种变体。然而，越来越多的证据表明，HP在中枢神经系统肿瘤中构成一个独立的实体。我们将17例患者的颅内和脊髓HP数据以及文献综述数据与脑膜瘤和外周HP进行了比较。脑膜和外周HP的性别比例、年龄分布、转移倾向相似，几乎从不呈多发性。这与脑膜瘤有根本区别。由于脑膜HP的特殊位置，其首次手术与复发或转移表现之间的间隔以及生存时间等其他数据无法与外周HP进行比较。脑膜HP的预后明显比脑膜瘤差，按照世界卫生组织的规定，HP介于恶性I级和II级之间。
