Abstract：
Spinal meningiomas are typically intradural lesions. Some may infiltrate the dura mater, thus exhibit direct extradural extension. Pure spinal epidural meningiomas are very rare. Here we present a 64 year-old-male with a purely extradural meningioma, and reviewed 15 previously reported cases from the literature.
A 64-year-old male presented with a progressive cauda equine syndrome. When Lumbar spine MRI showed two extradural lesions regarding the L3-L4 level, one was fully removed (i.e., the posterolateral lesion), while the other anterior lesion was left alone (i.e., to avoid potential neurologic sequelae). Pathologically, the lesion was a benign meningioma.
Spinal epidural meningiomas are rare and should optimally be fully excised at the index surgery.

摘要：
■脊髓脑膜瘤是典型的硬膜内病变。有些人可能会渗入硬脑膜，因此表现出直接的硬膜外延伸。单纯的脊髓硬膜外脑膜瘤非常罕见。这里我们介绍一个64岁的男性，患有纯粹的硬膜外脑膜瘤，并回顾了以前从文献中报道的15例病例。
■一名64岁男性出现进行性马尾神经综合征。当腰椎MRI显示两个关于L3-L4级别的硬膜外病变时，一个被完全移除(即，后外侧病变)，而其他前部病变则单独留下(即，以避免潜在的神经系统后遗症)。病理上,病灶为良性脑膜瘤.
结论：脊髓硬膜外脑膜瘤是罕见的，最好在初次手术时完全切除。
