Two ependymomas in adults, extending into both lateral ventricles have been reported. The final diagnosis was achieved by cranial computed tomography. This was particularly important in the first case while the clinical course and the previous diagnostic methods as angiography and isotope scintigraphy were misleading, suggesting a demyelinating process. This patient died because of a rare complication: intraoperatively evolved extradural, frontobasal hematoma which diagnosed again by CT-scan, but the removal of the hematoma was not performed on due time. In the second case a similar, but larger tumor could be removed successfully after CT diagnosis. The importance of CT-scan in diagnosis and operative decision of intraventricular tumors was emphasized.
已有报道称，两名成人室管膜瘤延伸至双侧脑室。最终诊断通过头颅计算机断层扫描得以实现。这在第一例病例中尤为重要，因为其临床病程以及先前的诊断方法如血管造影和同位素闪烁扫描具有误导性，提示为脱髓鞘病变。该患者死于一种罕见并发症：术中出现硬膜外额底部血肿，通过CT扫描再次确诊，但血肿未及时清除。在第二例病例中，经CT诊断后成功切除了一个类似但更大的肿瘤。强调了CT扫描在脑室肿瘤诊断和手术决策中的重要性。
