Overview

Head CT scan may be diagnostic of meningioma. Some of the findings on CT scan suggestive of meningioma include edema, CSF attenuation cleft, round/elongated extraaxial mass, and hyperostosis of the adjacent skull. Although MRI is the diagnostic study of choice, CT is easier to use and may be used in cases where there is a contraindication to the use of an MRI.

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]

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.
