Three cases of meningioma showing hyaline-like inclusions by light microscopy were studied at the fine structural level. The hyaline-like inclusions were found to be cyst-like contents of variable size filled with moderately dense finely filamentous material arranged either in a reticulated configuration or closely packed and appearing relatively homogeneous and dense. The surrounding cyst membrane is characterized, especially in the smaller inclusions, by the presence of microvilli. The reticulated material is found at the inner aspect of the cyst membrane and is attached to it. It is identical to the coating material seen at the surface of various epithelia. In addition to the filamentous material, minute membrane-bounded vesicles are often found floating within the larger cysts. The inclusions apparently begin as small, microvillous-filled cysts which eventually cluster and presumably fuse to form a single large body.
对3例经光学显微镜检查显示有透明样包涵体的脑膜瘤进行了超微结构水平的研究。发现透明样包涵体为大小不一的囊样内容物，充满中等密度的细纤维状物质，这些物质呈网状排列或紧密堆积，显得相对均匀且致密。周围的囊膜，尤其是在较小的包涵体中，其特征是存在微绒毛。网状物质位于囊膜内侧并与之相连。它与在各种上皮表面所见的覆盖物质相同。除了纤维状物质外，在较大的囊肿内还经常发现有微小的膜性小泡漂浮。这些包涵体显然最初是小的、充满微绒毛的囊肿，最终聚集并可能融合形成一个单一的大物体。
