On the basis of 26 cases with extracerebral fluid accumulation in the middle cranial fossa the bony changes occurring in this connection are described and discussed in respect of their aetiology. If there are bony accompanying reactions, two entities can be observed in principle. One group shows thinning and protrusion of the temporal squama, raising of the lesser wing of the sphenoid bone and protrusion of the greater wing of the sphenoid bone. The second group is associated with thickening of the temporal squama and of the lesser and greater wing of the sphenoid bone without showing any change in volume of the middle cranial fossa. If we postulate in the first group a space-occupying property of the extracerebral fluid accumulation, the prominent reactions in the second group are those usually associated with absence of pressure exercised on the cranial vault by a space-occupying growth.
基于26例中颅窝脑外积液病例，描述并讨论了与此相关的骨质改变及其病因。若存在骨质伴随反应，原则上可观察到两种情况。一组表现为颞鳞变薄并突出、蝶骨小翼抬高以及蝶骨大翼突出。第二组则与颞鳞、蝶骨小翼和大翼增厚相关，而中颅窝体积无任何变化。如果我们假定第一组中脑外积液具有占位性，那么第二组中显著的反应通常与占位性病变对颅顶无压力作用有关。
