Meningioma is one of the most common tumors of the spinal canal. Spinal meningiomas are usually found
in the thoracic spine and intradural extramedullary space. Intraspinal clear cell meningiomas are a rare
histological variant. Fewer than 20 intraspinal cases have been reported in the literature and only two
cases have been reported in the Korean literature, but there is no report available in the Korean orthopedic
literature. We report here on a case of an intraspinal clear cell meningioma that was found in the thoracic
region and it was completely resected. The nonspecific MR imaging characteristics make the diagnosis
of this tumor difficult. Histological examination must be used to differentiate clear cell meningiomas from
other tumors. Clear cell meningioma represents an aggressive variant of meningiomas, and surgical
reatment and adjuvant radiotherapy are though to be essential. Further more, long term follow-up
observation will be needed for detecting recurrence of clear cell meningioma.ope
