BACKGROUND
Subependymomas are rare in the spinal cord. They are typically expansile, intramedullary spinal cord masses, eccentrically located with minimal gadolinium enhancement.
CASE DESCRIPTION
We present a case of subependymoma originating from the cervical cord with an unusual exophytic appearance. Hallmarks of subependymoma and treatment are reviewed.
CONCLUSIONS
This is the first case, to our knowledge, where imaging revealed a mass appearing to be completely extramedullary with a primary exophytic component. Therefore, subependymomas should remain on the differential for masses in the spinal cord that appear extramedullary and exophytic.
背景
脊髓室管膜下瘤较为罕见。它们通常为膨胀性、脊髓内肿块，偏心性生长，仅有轻微钆增强。
病例描述
我们报告 1 例起源于颈髓的室管膜下瘤，具有不同寻常的外生性表现。复习室管膜下瘤的特征和治疗方法。
结论
据我们所知，这是首例影像学检查显示完全髓外、主要为外生性成分的脊髓室管膜下瘤病例。因此，对于表现为髓外外生性的脊髓内肿块，应考虑室管膜下瘤。
