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 helpful in the diagnosis of meningioma. Findings on CT scan suggestive of/diagnostic of meningioma include:[1][2]

  • Round or elongated extraaxial mass
  • Mass with broad attachment to the dura
  • Isodense mass. Can often be hyperdense or slightly hypodense compared to the cerebrum
  • CSF attenuation cleft
  • Tumor intense enhancement
  • Homogeneous mass that can show heterogeneity depending on the presence of fat, calcium, or tumor necrosis
  • Hyperostosis of adjacent skull in benign meningiomas
  • Edema
  • Mixed solid and cystic mass in clear cell meningiomas

Despite MRI being the imaging study of choice, CT is more widely available, better in urgent settings, and used when patients have a contraindication to MRI usage such as pacemakers.
