Diagnosis and microsurgical treatment of intracranial subependymoma:report of 33 cases

Abstract

Objective To explore the clinical characteristics and treatment of intracranial subependymoma.Method 33 patients with intracranial subependymoma treated with microneurosurgical management at Beijing Tiantan Hospital from 1998 to 2008 were analyzed retrospectively.Results In this serials,19 patients were in male and 14 patients in female.Tumors located in the lateral ventricles in 18cases,located in the fourth ventricle in 13 cases,intra -brain tissue in 2 cases.On MRI scans,the tumors showed iso/hypointensity on T1 - weighted and hyperintensity on T2 - weighted images.On enhanced scans,the tumors showed no enhancement or only slightly enhancement.Tumors located in the lateral ventricles,were totally removed in 13 cases and subtotal in 5 cases; tumors located in the fourth ventricle,were totally removed in 3 cases,subtotally in 7 cases and partial in 3 cases;tumors were subtotally removed in 2 cases in intra- brain tissue type.Conclusions MRI may contribute to diagnose the intracranial subependymoma and surgical management.Radical resection usually contributes to a good outcome.
