There is a well-defined left frontoparietal broad-based extra-axial mass measuring (40 x 37 x 26 mm). The extra-axial location is evidenced by a thin rim of CSF around the mass " CSF cleft sign". It elicits an isosignal to the cortical grey matter on both T1/T2 with cystic areas of low T1 and high T2 as well as signal void vessels and mild surrounding vasogenic oedema. A vivid and heterogeneous enhancement is noted on the postcontrast sequences with a "dural tail sign". Thickening of the adjacent diploe is noted. The ADC was ~ 1152 x 10-6 mm2/s.
