The question of whether meningeal hemangiopericytoma is a variant of meningioma ("angioblastic meningioma") or a nosologically distinct entity remains controversial. We present the case histories of an intracranial meningioma and of a meningeal hemangiopericytoma, both of which developed extracranial metastases. The metastatic lesions in both cases were studied by electron microscopy, which demonstrated pericytomatous differentiation in one instance and meningothelial differentiation in the other. This report supports the opinion that meningeal hemangiopericytomas and meningiomas of the CNS are distinct pathological entities.
脑膜血管外皮细胞瘤是脑膜瘤的一种变体（“血管母细胞性脑膜瘤”）还是一种分类学上不同的实体，这一问题仍存在争议。我们展示了一例颅内脑膜瘤和一例脑膜血管外皮细胞瘤的病例史，二者均发生了颅外转移。对两例病例的转移病灶进行了电子显微镜研究，其中一例显示为血管外皮细胞瘤样分化，另一例显示为脑膜内皮分化。本报告支持以下观点，即中枢神经系统的脑膜血管外皮细胞瘤和脑膜瘤是不同的病理实体。
