The authors report a case of large arachnoid cysts of the posterior fossa treated by endoscopic surgery. A 40-year-old man was admitted with a 3-month history of headache and progressive gait imbalance, with no significant medical history. At the time of admission, neurological examination revealed no abnormalities except for tandem imbalance. Brain computerized tomography (CT) scan and magnetic resonance imaging (MRI) revealed a posterior fossa arachnoid cyst (PFAC) causing brain stem compression accompanied by hydrocephalus. The patient was treated by endoscopic fenestration of the cyst with a paramedian suboccipital transcortical approach. Postoperatively the patient's complaints showed improvement and he was discharged with no complications. Follow up MRI showed a decrease in the cyst's size and the hydrocephalus with decompression of the brain stem.
作者报告了一例采用内镜手术治疗的后颅窝大型蛛网膜囊肿病例。一名40岁男性因头痛3个月和进行性步态不稳入院，无明显病史。入院时，神经系统检查除串联不稳外无异常。脑部计算机断层扫描（CT）和磁共振成像（MRI）显示后颅窝蛛网膜囊肿（PFAC）导致脑干受压并伴有脑积水。患者采用经枕下旁正中皮质入路进行囊肿内镜开窗术治疗。术后患者的症状有所改善，出院时无并发症。随访MRI显示囊肿大小减小，脑积水减轻，脑干减压。
