Abstract
Four cases of choroid plexus papilloma (CPP) obtained at the time of surgical excision were examined by electron microscopy and compared with normal choroid plexus (CP) of mouse and chick. In apical tight junctions fusion of the two outer leaflets of the adjacent cytoplasmic membrane was verified as in CP. This fact suggests that there is a blood-CSF barrier not only in CP but also in CPP.
摘要
对手术切除时获取的4例脉络丛乳头状瘤（CPP）进行了电子显微镜检查，并与小鼠和鸡的正常脉络丛（CP）进行了比较。在顶端紧密连接处，相邻细胞质膜的两个外小叶融合，这与脉络丛中的情况相同。这一事实表明，不仅在脉络丛中存在血脑屏障，在脉络丛乳头状瘤中也存在。
