A Case of Subcortical Meningioma

Summary

¶ Subcortical meningioma, which has been reported as meningioma without dural attachment, a cerebral subcortical lesion, is extremely rare. Very few findings of radiological examination of subcortical meningioma have been described. Pre-operative differentiation of this lesion is generally difficult. We characterize the peritum oural oedema adjacent to the meningioma in this region, and we suggest that radiological findings of peritum oural oedema contribute to differential diagnosis of subcortical meningiomas.
