Agar-gel electrophoresis of the pericerebral fluid and more recent data obtained from CT-Scan examination suggest the presumably important role of external subarachnoid hydrocephalus in postmeningitic pericerebral effusions of infancy. Postmeningitic subarachnoid hydrocephalus results very likely from an impeded resorption at the level of the arachnoid villi and venous sinuses; in some cases, however, there could be a coincidental occurrence of meningitis and pericerebral effusion from a distinct origin. The presence of a pericerebral effusion correlates badly with the seriousness of the clinical condition, whilst its spontaneous tendency to resorption is obvious in many cases, leading to a more conservative attitude. Fontanometry seems helpful when discussing the indication to operate. If surgery is required, it will usually be limited to a minor procedure; we perform, in such cases, an external drainage that can be transformed, if necessary, into an internal shunt.
脑周液的琼脂凝胶电泳以及近期CT扫描检查获得的数据表明，外部蛛网膜下腔脑积水在婴儿期脑膜炎后脑周积液中可能起重要作用。脑膜炎后蛛网膜下腔脑积水很可能是由于蛛网膜绒毛和静脉窦水平的吸收受阻所致；然而，在某些情况下，可能会同时发生源于不同病因的脑膜炎和脑周积液。脑周积液的存在与临床病情的严重程度相关性较差，而在许多情况下其自发吸收的倾向很明显，这导致了更为保守的态度。在讨论手术指征时，囟门测压似乎有帮助。如果需要手术，通常将其限制在一个小手术；在这种情况下，我们进行外部引流，如有必要可将其转换为内部分流。
