Known as the paraphysis cyst, or the colloid cyst of the third ventricle, the lesion described in this study continues to have an unprecise etiology in spite of a great number of investigations. This series of 75 anatomo-clinical cases with this lesion provides sufficient material for a valuable statistical analysis. After enumerating the different cerebral symptoms of this disease, the author makes a macroscopic and microscopic morphological analysis and compares his own results with those found in literature. The embryologic investigations mentioned and the hypotheses to which they lead do not shed light on the origin of these cysts. The mathematical analysis indicates a difference in frequency between both sexes, with a far greater frequency in males. Referring to the grey commissure's agenesia, mentioned by Morel as statistically more frequent in men than in women, the author concludes that the colloid cysts of the third ventricle are also to be considered as a cerebral anomaly related to sex.
这种病变被称为旁突体囊肿或第三脑室胶样囊肿，尽管进行了大量研究，但本研究中描述的病变病因仍不明确。这一系列75例患有该病变的解剖临床病例为有价值的统计分析提供了充足的材料。在列举了该疾病的不同脑部症状后，作者进行了宏观和微观形态学分析，并将自己的结果与文献中的结果进行了比较。所提及的胚胎学研究及其得出的假设并未阐明这些囊肿的起源。数学分析表明两性之间在发病率上存在差异，男性的发病率远高于女性。作者提及莫雷尔指出的灰质连合发育不全在男性中的统计学发病率高于女性，得出结论认为第三脑室胶样囊肿也应被视为一种与性别相关的脑部异常。
