A right sided extra-axial mass arises from the inner surface of the skull vault, adjacent to the superior sagittal sinus which it invades and occludes. The mass is isointense to grey matter on both T1 and T2 with vivid contrast enhancement. It is also isointense on DWI. Unfortunately ADC is not available. No particularly prominent flow voids. It is surrounded by vasogenic oedema. The overlying bone is abnormal with loss of the normal fatty marrow and tumour can be extending beyond the outer table.
