There is an expansile coarse trabeculated intraosseous lesion of the right parietal bone with thinning of the internal and external skull tables. It appears non-homogeneously, hypo-to-isointense on T1WI, hyperintense on FLAIR and T2WI with inhomogeneous enhancement following IV contrast. A mass effect is noted on the adjacent parietal lobe as well as the superior sagittal sinus which remains patent. No intra-axial extension seen.
In the cervical region on the sagittal T1 sequence, there is an abnormal appearance at the C4-C5 level.
