Ependymomas are commonly reported at an intradural intramedullary location and more frequently at the conus medullaris or filum terminale. In comparison to this, the incidence of spinal tumors being reported at an intradural extramedullary site is less. We describe a young patient who presented with urinary retention and a long-standing history of back pain radiating to the right lower limb. Imaging revealed an intradural ependymoma extending from D11 to S1 and measuring 21 cm in length. The patient underwent D10 to S1 laminectomy. Although the tumor originated from the conus medullaris, the histological evaluation revealed a WHO grade II ependymoma, which is rare, as only 30% of tumors in this location are non-myxopapillary.
室管膜瘤常见于硬脊膜内髓内位置，更常见于圆锥或终丝部位。相比之下，硬脊膜外髓外部位的脊柱肿瘤报道发病率较低。我们描述了一名年轻患者，该患者出现尿潴留以及长期背痛并向右下肢放射。影像学检查显示一个从胸11延伸至骶1的硬脊膜内室管膜瘤，长度为21厘米。患者接受了胸10至骶1椎板切除术。尽管肿瘤起源于圆锥，但组织学评估显示为世界卫生组织二级室管膜瘤，这种情况较为罕见，因为该部位只有30%的肿瘤是非黏液乳头型的。
