Chordoid meningioma, classified as atypical meningioma according to the World Health Organisation (WHO) classification, is a rare subtype, which represents only 0.5% of all meningiomas and is associated with a high incidence of recurrence. Multiple intracranial meningiomas are rare in non-neurofibromatosis patients. We present a female patient with both of these rare types of meningioma. The patient presented with two concurrent intracranial meningiomas, with one a meningotheliomatous subtype and the other a chordoid meningioma. Given the wide array of histological differential diagnoses in chordoid meningioma, immunohistochemistry has a significant role to play in differentiating them. Recurrence in chordoid meningioma can be generally predicted based on the extent of resection, the percentage of chordoid element, and proliferation indices.
脊索样脑膜瘤根据世界卫生组织（WHO）分类被归类为非典型脑膜瘤，是一种罕见的亚型，仅占所有脑膜瘤的0.5%，且复发率高。在非神经纤维瘤病患者中，多发性颅内脑膜瘤很少见。我们报告了一名患有这两种罕见类型脑膜瘤的女性患者。该患者同时患有两个颅内脑膜瘤，一个是脑膜上皮型亚型，另一个是脊索样脑膜瘤。鉴于脊索样脑膜瘤存在广泛的组织学鉴别诊断，免疫组化在鉴别诊断中具有重要作用。脊索样脑膜瘤的复发通常可根据切除范围、脊索样成分百分比和增殖指数来预测。
