Ependymomas rarely occur outside the CNS. Of those that do, the majority are in the sacrococcygeal or presacral areas.

室管膜瘤很少见于中枢神经系统之外，假如有的话，主要见于骶尾部或骶前区。

Because fourth ventricular subependymomas can have calcification and contrast enhancement more typical of ependymomas, diagnostic imaging is more challenging.

由于四脑室的室管膜下瘤更容易出现钙化，增强扫描多有强化，其诊断更具有挑战性。

Here is an ependymoma arising from the ependymal lining of the fourth ventricle above the brainstem and bulging toward the cerebellum. Ependymomas are benign histologically.

发生在脑干之上第四脑室室管膜的室管膜瘤。组织学上，室管膜瘤是良性肿瘤。
