Meningiomas account for approximately 15% of all intracranial tumors and are the most common non-glial primary tumors of the central nervous system. Most meningiomas are benign neoplasms with characteristic imaging features. Primary extradural meningiomas account for only 1-2% of all meningiomas. They must be differentiated from intradural meningiomas with secondary extradural extension and/or metastases. The vast majority of extradural meningiomas are found in the skull or in the head and neck region. We report on an extremely rare case of primary extradural meningioma that was located in the scapula. The lesion was resected. Radiographic findings and pathologic features are discussed. To the best of our knowledge, this form of presentation of an extradural meningioma has not been previously described.
脑膜瘤约占所有颅内肿瘤的15%，是中枢神经系统最常见的非神经胶质原发性肿瘤。大多数脑膜瘤是具有特征性影像学表现的良性肿瘤。原发性硬膜外脑膜瘤仅占所有脑膜瘤的1-2%。它们必须与伴有继发性硬膜外扩展和/或转移的硬膜内脑膜瘤相鉴别。绝大多数硬膜外脑膜瘤位于颅骨或头颈部区域。我们报告一例极为罕见的原发性硬膜外脑膜瘤，其位于肩胛骨。该病变已被切除。文中讨论了影像学表现和病理特征。据我们所知，这种硬膜外脑膜瘤的表现形式此前尚未见报道。
