A newborn girl was admitted suffering from convulsive seizures in both legs. A computed tomography (CT) scan revealed bilateral symmetrical middle cranial fossa arachnoid cysts and intraventricular hemorrhage. In the course of a year, only the cyst on the right side became gradually larger; the cyst on the left side was reduced in size. At the age of 1 year and 2 months, her intellectual development was normal, but she could not stand by herself. On metrizamide-enhanced CT cisternography, the cyst on the right side was of a noncommunicating type. Membranectomy of the right-sided cyst was performed and the cyst proved to be of the intraarachnoid type. The postoperative course was uneventful and a CT scan, taken 10 months after the operation, revealed no abnormality on either side. The intellectual and motor development was normal, and no abnormality was observed by electroencephalography. This may be the first report of arachnoid cysts found in a neonate. It gives us clues for understanding the etiology of this disease, which has not been fully clarified.
一名新生女婴因双腿抽搐发作入院。计算机断层扫描（CT）显示双侧对称的中颅窝蛛网膜囊肿和脑室内出血。在一年的时间里，只有右侧的囊肿逐渐增大；左侧的囊肿则缩小。在1岁2个月时，她的智力发育正常，但还不能独自站立。在甲泛葡胺增强CT脑池造影中，右侧囊肿为非交通性类型。对右侧囊肿进行了囊肿切除术，结果证明囊肿为蛛网膜内型。术后过程顺利，术后10个月进行的CT扫描显示两侧均无异常。智力和运动发育正常，脑电图检查未发现异常。这可能是新生儿蛛网膜囊肿的首例报告。它为我们理解这种尚未完全阐明病因的疾病提供了线索。
