The plain film, computed tomography (CT) and angiographic findings in 10 patients with primary intraosseous meningioma were reviewed and the differential diagnosis considered. In nine patients with benign primary intraosseous meningioma, the radiological findings revealed intraosseous expansile growth. In one patient with the malignant form of the tumour, osteolytic growth was evident on plain film and CT. In eight patients, the tumour tissue was hyperdense (65-85 HU) on the unenhanced CT images and striking enhancement was shown in seven. In five patients angiography showed that the external carotid artery fed the tumour, while in one the vasculature was normal. Benign primary intraosseous meningioma showed expansile growth and malignant tumour showed osteolytic growth. If a combination of the plain film, angiogram and CT findings is considered, a diagnosis of the benign tumour can be made and a diagnosis of benign meningioma can be suggested.
回顾了10例原发性骨内脑膜瘤患者的平片、计算机断层扫描（CT）和血管造影表现，并考虑了鉴别诊断。在9例良性原发性骨内脑膜瘤患者中，影像学表现为骨内膨胀性生长。在1例恶性肿瘤患者中，平片和CT显示溶骨性生长。8例患者的肿瘤组织在未增强的CT图像上呈高密度（65-85 HU），7例显示明显强化。5例患者血管造影显示肿瘤由颈外动脉供血，1例血管结构正常。良性原发性骨内脑膜瘤表现为膨胀性生长，恶性肿瘤表现为溶骨性生长。如果综合考虑平片、血管造影和CT表现，则可做出良性肿瘤的诊断并提示为良性脑膜瘤。
