The gender ratio of patient with MCFAC adopted resection of arachnoid cyst and arachnoid cyst-peritoneal shunt was performed in 28 patients.Results Follow-up was performed for 3 months to 3 years. The headache completely disappeared in 75 patients (58.59%) and partial remission in 41 (32.03%) after the operation. The frequency and degree of seizures obviously decreased in 8 of the patients with MCFIAC. Eleven patients with dystropy,attention-deficit disorder or difficulty of learning got improvement.

Conclusion The clinical features of MCFAC is that it mainly occur in the left side of male. The younger the patient with MCFAC is, the better the treatment effect in the surgical intervention is. good outcome can be achieved by resection of the parietal layer of arachnoid cysts.
