MRI
Large extra-axial lesion at the right frontal lobe is isotense on T1-weighted sequence, isointense on T2-weighted sequence and demonstrates homogenous contrast enhancement. Central region of T2 hypointensity is consistent with calcification. Mild degree of diffusion restriction.
Mass effect with 10mm midline shift towards the left side. Narrowing and possible invasion of the anterior aspect of the superior sagittal sinus. Downward displacement of the right lateral ventricle and midbrain.
Conclusion: Appearance of the extra-axial lesion of the right parafalcine lesion is suggestive of meningioma.
