The AA., after having examined the various hypothesis reported in literature about the etiopathogenesis and the contrasting anatomical and pathological data concerning the arachnoid supratentorial cysts, point out the remarkable frequency of they malformative and above-all post-traumatic genesis. On the formation mechanism of this last type, they agree upon the supposition expressed by Taveras and Ransohoff in 1953. The AA., therefore, after having analysed the principal morphological and topographical aspects, pay attention to the present diagnostic possibilities, above all in radiological range, where the TAC represents, by this time, the examination of election compared with traditional assurances with means of contrast. It follows the analysis of the personal casuistry, consisting in 6 arachnoid supratentorial cysts, two of which clearly post-traumatic and two, very probably, of malformative genesis (for the coexistence of data in favour of both suppositions). The AA. draw these conclusions: the CT Scan is the only diagnostic means which permits an exact pre-operating diagnosis on the nature of the lesion; the surgical and, above all, anatomo-pathological reports assume an essential rule for an exact etiopathogenetic interpretation of the lesion examined.
作者在研究了文献中报道的关于蛛网膜幕上囊肿的病因发病机制以及相互矛盾的解剖学和病理学数据的各种假说后，指出其发育异常尤其是创伤后起源的显著频率。关于后一种类型的形成机制，他们认同1953年塔韦拉斯和兰索霍夫提出的假设。因此，作者在分析了主要的形态学和局部解剖学方面后，关注当前的诊断可能性，尤其是在放射学领域，此时与传统的造影检查相比，CT扫描是首选的检查方法。接下来是对6例蛛网膜幕上囊肿的个人病例分析，其中2例明确为创伤后囊肿，2例很可能是发育异常性起源（因为存在支持两种假设的数据）。作者得出以下结论：CT扫描是唯一能够对病变性质进行准确术前诊断的诊断方法；手术报告，尤其是解剖病理学报告，对于准确解释所检查病变的病因发病机制起着至关重要的作用。
