CASE REPORT
We report a case of a huge posterior fossa arachnoid cyst with hydrocephalus. This 15-month-old girl presented with macrocrania and psychomotor retardation. Magnetic resonance (MR) imaging demonstrated ventriculomegaly and a huge cystic lesion in the posterior fossa. A membranectomy was performed microscopically and the patient had a good postoperative course.
OUTCOME
Magnetic resonance imaging 1 year after the operation revealed adequate reduction in the size of the ventricle and cyst. Progressive macrocrania discontinued and normal development was obtained.
病例报告
我们报告一例伴有脑积水的巨大后颅窝蛛网膜囊肿病例。这名15个月大的女童表现为巨头症和精神运动发育迟缓。磁共振成像显示脑室扩大以及后颅窝有一个巨大的囊性病变。在显微镜下进行了囊肿切除术，患者术后恢复良好。
结果
术后1年的磁共振成像显示脑室和囊肿大小有适当缩小。巨头症进展停止，患儿获得了正常发育。
