Figure 1 (A-G): Plain CT scan (A) demonstrates an extensively calcifi ed, hyperdense, parafalcine, extra-axial mass. Axial T1W MRI image (B) reveals the mass to be predominantly hypointense with hyperintense calcifi cations (arrows). An axial T2W MRI image (C) shows it to be heterogeneously isohyperintense with marked perifocal edema. An axial diffusion-weighted MRI image (D) reveals lack of restriction of diffusion within the tumor. A contrast-enhanced T1W, sagittal MRI image (E) reveals diffuse heterogeneous enhancement with transcalvarial–subgaleal extension (arrows). A three-dimensional time-of-fl ight MRI angiography image (F) reveals extensive tumor neovascularity with splaying and posterolateral displacement of both anterior cerebral arteries (arrows). An MRI venography image (G) demonstrates thrombosis/invasion of the anterior one-third of the superior sagittal sinus (arrow)
