Abstract

Clear-cell meningioma is a rare disease entity showing a more aggressive nature, clinically, than those of other subtypes of meningioma. It occurs in younger persons and commonly in the spinal canal. The recurrence rate has been reported to be as high as 60%. We present a case of clear-cell meningioma in a 17-year-old man in whom initial MR imaging showed localized leptomeningeal enhancement that had progressed into the entire subarachnoid space after surgical resection of the primary tumor.

摘要

透明细胞型脑膜瘤是一种罕见的疾病实体,在临床上比其他亚型的脑膜瘤具有更强的侵袭性。它发生于较年轻的人群,且常见于椎管内。据报道,其复发率高达60%。我们报告一例17岁男性的透明细胞型脑膜瘤病例,该患者最初的磁共振成像显示局限性软脑膜强化,在原发性肿瘤手术切除后已进展至整个蛛网膜下腔。
