Objective To explore the clinical features and surgical indications of intracranial arachnoid cysts (IACs) and curative effect of the surgery on IACS. Methods The clinical data of 55 patients with IACs demonstrated by craniocerebral MRI or CT were analyzed. Of 55 patients with IACs, 29 were conservatively treated and 26 surgically treated. Of 26 patients treated by surgery, 18 were treated by microsurgical excision or fenestration of IACs walls and 8 by cystoperitoneal shunt (in 7 patients) or cystoatrial shunt (in 1 patient). Results The following-up from 3 months to 5 years (mean, 15 months) symptoms. CT or MRI showed that the IACs shrank or disappeared in 15 patients (83.3%, 15/18) treated by microsurgical excision or fenestration and 5 (62.5%, 5/8) treated by the shunt. Conclusion The major indications of surgery for IACs include the intractable seizures, intracranial hypertension and compression of the cerebral tissues. The excision or fenestration of IACs walls and communicating the cyst with arachnoid cistern by microsurgery through keyhole approach is a safe, effective and optimal method to treat IACs.
