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]

Head CT scan may be helpful in the diagnosis of meningioma. Findings on CT scan suggestive of/diagnostic of meningioma include:

Round or elongated extraaxial mass
Mass with broad attachment to the dura
Isodense mass. Can often be hyper dense or slightly hypo dense 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
