Evaluate the outcome of children with prenatally diagnosed arachnoid cysts.
Retrospective study of seventeen cases of children who were diagnosed with an arachnoid cyst during prenatal MRI between July 1994 and January 2007 and followed up for a mean 6 years and 6 months. Follow-up was based on evaluation of clinical files and contacts with the physicians who were following the children. The children were divided into three groups: group 1 normal development, group 2: minor clinical signs, normal schooling, group 3: major clinical symptoms, schooling disturbed.
Eight of the 17 patients included in this study underwent derivation surgery for the cyst. Eight of the 17 children were in group 1, and 3 in group 2. Four of the 6 children in group 3 had associated symptoms. Two of the children in group 3 present with a supratentorial cyst, and 4 with a cyst of the posterior fossa.
The prenatal diagnosis of a arachnoid cyst should be accompanied by a search for associated lesions. The risk of hydroencephalitis should be explained to the parents.
评估产前诊断为蛛网膜囊肿患儿的预后情况。
对1994年7月至2007年1月期间在产前MRI检查中被诊断为蛛网膜囊肿的17例患儿进行回顾性研究，平均随访6年6个月。随访基于临床档案评估以及与患儿主治医生的联系。将患儿分为三组：第1组发育正常；第2组有轻微临床症状，学业正常；第3组有严重临床症状，学业受影响。
本研究纳入的17例患者中有8例因囊肿接受了引流手术。17名儿童中，8名属于第1组，3名属于第2组。第3组的6名儿童中有4名伴有相关症状。第3组中有2名儿童患有幕上囊肿，4名患有后颅窝囊肿。
产前诊断出蛛网膜囊肿时，应同时检查是否存在相关病变。应向家长解释发生脑积水的风险。
