Bielchowsky于1902年首次报告幕上成血管细胞瘤。其后在文献上又有50例的报告。然而这些幕上的成血管细胞瘤究竟是真正的成血管细胞瘤抑或是成血管性脑膜瘤呢?尚有争论。在文献报告的308例成血管细胞瘤中,93.8%位于后颅窝,3.2%位于脊髓,仅2.9%位于幕上。在Paillas报告的一组3000例手术证实的脑瘤中,仅1%是成血管细胞瘤且全部位于后颅窝。Morello报告一组1483例原发性幕上新生物,仅2例为成血管细胞瘤。本文报告一例没有 Bipolarchowsky first reported supratentorial angioblastoma in 1902. Then there were 50 reports in the literature. However, whether these hemangioblastomas on the epidermis are true hemangioblastomas or angiogenic meningioma are still controversial. Of the 308 hemangioblastomas reported in the literature, 93.8% were located in the posterior fossa, 3.2% were in the spinal cord, and only 2.9% were located in the supratentorial space. Of the group of 3000 surgically-reported brain tumors reported by Paillas, only 1% were hemangioblastomas and all were located in the posterior fossa. Morello reported a group of 1483 primary supratentorial neoplasms, only 2 hemangioblastomas. This article reports an example
