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.

CT Scan

• Head CT scan may be diagnostic of meningioma.
• Findings on CT scan suggestive of meningioma include:

• Homogeneously hyperdense lesion
• Calcification
• Hyperostosis
• Lytic lesions
• Pneumosinus dilatans

• Meningioma is highly vascularized thus it is readily visualized with contrast head CT scan.
• 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.
