This is a case of a meningioma with all of the classic MRI findings, except for location. Meningiomas arise from the arachnoid cap cells of the meninges. They are supratentorial in 90% of the time, which is why this case isn’t entirely a classical. Meningiomas are benign neoplasms, however, they can cause real symptoms and be very dangerous, as in this case. They are typically T1 hypo to isointense (first image above), T2 hypointense (second image above), and enhance homogenously (last image above). They typically have a broad based dural attachment and extension which has been described as a “dural tail,” and they also have a CSF cleft as seen in the third image above.
