This study concerns 51 cases of cystic @entity816 of the @entity1779 . At operation these @entity5 closely resembled @entity76 , presenting as a big cyst contiguous with the lateral ventricle and containing a small mural nodule. The nodule was in a deep location in 26 cases, and always showed marked contrast enhancement on computerized tomography scans. The most frequent presenting symptom was @entity302 (68%), and the most common sign was @entity1829 (85%). The major goal of surgery was extirpation of the nodule. The follow-up period of the 34 cases available for long-term review ranged from 6 to 31 years (mean 17 years). Of these, 28 @entity1 (82%) had a good outcome; four (12%) had a fair result, and two (6%) had a poor response. An analysis of these results shows that total extirpation of the mural @entity5 was associated with the best outcome, whether or not the cyst wall was completely removed. Radiation therapy was irrelevant to the prognosis for these @entity1 . On the other hand, partial excision of the nodule, correlated with the deep location of the @entity5 , was the cause of the two poor results in this series and resulted in multiple operations for recurrences in two other @entity1 . Nevertheless, two of these @entity1 are still alive and well many years after incomplete surgical treatment. On the basis of this study, the importance of recognizing the occurrence of this "benign" @entity5 of the @entity1779 is stressed, and the hypothesis of a common origin from subependymal glia of all @entity816 is supported.
