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.
■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。
