Multilocular hydrocephalus is a complication of neonatal hydrocephalus. Its main feature is the presence of multiple cysts inside the ventricles, which requires a specific therapeutic approach. The case of a preterm infant with intracranial hemorrhage grade II-III and central nervous system infection is reported. The cysts developed at the subependymal layer in the posterior area of the patient's thalamus. Their growth and development were charted by ultrasound imaging for several weeks. These types of cysts may grow to occupy the totality of the lateral ventricles, isolating the temporal horns. Of all the reviewed pathogenic mechanisms, we support the hypothesis of an inflammatory vasculitis at the subependymal level, with the subsequent infarct giving rise to the cysts. The osmotic pressure within the cavities, rather than intraventricular fluid, would account for the enlargement of the cysts.
多房性脑积水是新生儿脑积水的一种并发症。其主要特征是脑室内存在多个囊肿，这需要特定的治疗方法。本文报道了一例患有II - III级颅内出血和中枢神经系统感染的早产儿病例。囊肿在患者丘脑后部的室管膜下层形成。通过超声成像对其生长发育情况进行了数周的记录。这类囊肿可能会生长并占据整个侧脑室，使颞角孤立。在所有经审查的致病机制中，我们支持室管膜下水平炎症性血管炎的假说，随后的梗死导致了囊肿的形成。囊肿腔内的渗透压而非脑室内的液体，是囊肿增大的原因。
