Vague headaches for investigation.
Extra axial homogeneously enhancing mass lesion with dural tail is seen overlying the right frontal cerebral convexity. It has very high T2 signal. No adjacent hyperostosis or bony change; no edema.
2 case questions available
These selected images of a meningioma demonstrate how vessels coursing through the subarachnoid space can help confirm that the mass is extra-axial. The high T2 signal nature of this meningioma is not typical, but seen in a number of histological variants, particularly secretory meningiomas, angiomatous meningiomas, chordoid meningiomas and microcystic meningiomas. Absent adjacent edema makes secretory meningioma less likely.
Unfortunately pathological proof is unavailable, however I believe this was confirmed.
