Dorsolumbar intradural extramedullary ependymoma is a rare entity. Spinal metastases in patients with intracranial ependymoma are well described, but it is extremely rare for a spinal ependymoma to metastasize to brain. We describe a case of aggressive dorsolumbar intradural extramedullary ependymoma mimicking arachnoid cyst radiologically, which developed intracranial metastasis.
硬脊膜内外髓外室管膜瘤是一种罕见的实体。颅内室管膜瘤患者的脊柱转移已有很好的描述，但脊髓室管膜瘤转移到脑部极为罕见。我们描述了一例侵袭性硬脊膜内外髓外室管膜瘤，在影像学上类似蛛网膜囊肿，发展为颅内转移。
