弥漫分布的胞浆透亮的瘤细胞；丰富的毛细血管；年轻男性——血管母细胞瘤

特点：WHO I 级，多发生在小脑，部分与von Hippel -Lindau综合征有关。

 

Though WHO grade I capillary hemangioblastoma is a good thought, I have to raise the possibility of WHO grade I angiomatous meningioma. Angiomatous meningioma often shows features of microcystic meningioma, and can sometimes be very difficult to distinguish from hemangioblastoma. Please look and see if there are any subtle meningothelial whorls, psammoma bodies, or large and isolated stromal cells (with hyperchromatic, irregularly shaped nuclei and vacuolated lipidized). Upload a few more photos taken at focus will certainly help. If still in doubt, do immunohistochemical stains to confirm.
