Overview
Head CT scan may be diagnostic of meningioma. Findings on CT scan suggestive of meningioma include homogeneously hyperdense lesion, calcification, hyperostosis, lytic lesions and pneumosinus dilatans.[1]
CT Scan
- Head CT scan may be diagnostic of meningioma.[1]
- Findings on CT scan suggestive of meningioma include:[1]
- Homogeneously hyperdense lesion
- Calcification
- Hyperostosis
- Lytic lesions
- Pneumosinus dilatans
- Meningioma is highly vascularized thus it is readily visualized with contrast head CT scan.[1]
- Head CT scan confirms the location of the meningioma and illustrates any invasion to the surrounding brain tissue.
- Head CT scan may be used to determine if the meningioma could be surgically resected.
