Convexity meningioma

Axial, sagittal, and coronal images reveal a round extra-axial lesion, with a broad base along the dura of the convexity, and a small associated dural tail. Additional typical findings for the diagnosis include relative isointensity to brain on the T1-weighted scan, slight hyperintensity on T2-weighted scans, and homogeneous contrast enhancement.
