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:
  • 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.
