Abstract：
Intracranial meningeal convexity chondroma is a rare benign lesion hypothesized to stem from remnant chondrocyte precursors of embryonic origin. This lesion often masquerades as meningioma given the similar dural-based attachment and pattern of calcification. We describe the case of a 26-year-old female with incidentally discovered convexity meningeal chondroma, originally presumed to be a meningioma. In this case, we share our diagnostic and operative intervention and outcome and discuss the unique pathologic findings in this lesion that differentiate it from similar appearing lesions. To the authors\' knowledge, there are fewer than 20 cases of convexity meningeal chondroma in the literature; thus, we also provide a brief review of the literature regarding this rare pathology.
摘要：
颅内脑膜凸性软骨瘤是一种罕见的良性病变，假设源于胚胎起源的残余软骨细胞前体。鉴于类似的基于硬脑膜的附着和钙化模式，该病变通常伪装成脑膜瘤。我们描述了一名26岁女性偶然发现的凸性脑膜软骨瘤的病例，最初推测是脑膜瘤.在这种情况下,我们分享我们的诊断和手术干预和结果，并讨论该病变的独特病理发现，将其与类似的病变区分开来。就作者所知，文献中的凸脑膜软骨瘤少于20例；因此，我们还对这种罕见病理的相关文献进行了简要回顾.
