Abstract
A 34-year-old female patient was presented with leg and hip pain for 6 months as well as voiding difficulty for 1 year. Magnetic resonance imaging revealed a well-demarcated mass lesion at L2-3. The mass was hypo-intense on T1- and T2-weighted images with homogeneous gadolinium enhancement. Surgery was performed with the presumptive diagnosis of intradural extramedullary meningioma. Complete tumor removal was possible due to lack of dural adhesion of the tumor. Histologic diagnosis was clear cell meningioma, a rare and newly included World Health Organization classification of meningioma usually affecting younger patients. During postoperative 2 years, the patient has shown no evidence of recurrence. We report a rare case of cauda equina clear cell meningioma without any dural attachment.
摘要
一名34岁女性患者出现腿部和髋部疼痛6个月，排尿困难1年。磁共振成像显示L2 - 3水平有一个边界清晰的肿块。该肿块在T1加权和T2加权图像上呈低信号，钆增强均匀。手术时初步诊断为硬脊膜内髓外脑膜瘤。由于肿瘤未与硬脑膜粘连，得以完整切除肿瘤。组织学诊断为透明细胞型脑膜瘤，这是一种罕见的、世界卫生组织新纳入的脑膜瘤分类，通常影响年轻患者。术后2年，患者无复发迹象。我们报告一例罕见的马尾神经透明细胞型脑膜瘤，无任何硬脑膜附着。
