Abstract
Introduction and importance
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.
Case presentation and clinical discussion
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.
Conclusions
Spinal epidural meningiomas are rare and should optimally be fully excised at the index surgery.
