[en] The imaging features and diagnosis of primary intraosseous meningioma were studied. Eight cases of primary intraosseous meningioma examined with plain film, angiogram and CT were reviewed. Seven cases of benign primary intraosseous meningioma showed intraosseous expansible growth; one malignant tumor appeared as an osteolytic growth on plain film and CT scan. Six cases were hyperdense (65-85 HU) on plain CT scan, five cases demonstrated marked enhancement on postcontrast CT scan. Angiogram revealed external carotid artery feeding the tumor in 4 cases and one case was normal. Conclusion: Combining the findings of plain film, angiogram and CT scan, it is possible to make a diagnosis of intraosseous meningioma
