Abstract
Subependymoma is rare, and little is known regarding subependymoma intratumoral hemorrhage. A retrospective study of subependymoma was performed, and 4 cases of intratumoral hemorrhage from 61 subependymomas were collected. All 4 cases were pathologically confirmed to be subependymoma and showed a benign character. After complete subependymoma resection, the 4 patients achieved favorable outcomes; however, pathology showed that dilated thin-wall vessels and/or hyalinosis of the vessel walls existed in all 4 cases. The present series showed that subependymomas with hemorrhage and benign pathology are rather rare and that surgical treatment results in good prognosis. The present series supports the hypothesis that the pathology of vascular degeneration may contribute to subependymoma hemorrhage.
