Abstract:
OBJECTIVETo investigate the diagnostic method and analyze the result of microneurosurgical treatment for tumors of the fourth cerebral ventricle.
METHODSTumor of the fourth ventricle was clinically diagnosed in 86 patients basing on the preliminary assessment of symptom and CT or MRI findings. Of these 86 patients treated with micro-neurosurgery, the tumors in 62 were totally removed, subtotally in 19, and partially in 5. Forty-two patients received postoperative radiotherapy.
RESULTSThree patients died postoperatively within ten days, and symptoms in 83 were improved after treatment. The average survival period was over 3 years. The pathology included 32 medulloblastomas, 23 ependymoma, 15 astrocytoma, 10 hemangiblastomas, 2 choroid plexus papillomas, and 4 epidermoid cysts.
CONCLUSIONMedulloblastoma, astrocytoma and hemangiblastoma are suggested to be removed totally whenever technically possible according to the site, character and volume of the tumor. For ependymoma, if close to the brain stem, is recommended to be subtotally removed. Postoperative radiotherapy may be beneficial for malignant types.
