There is a large extra-axial calcified mass overlying the right frontal lobe. It is mostly calcified with expected hypointense signal on T1/T2 within areas of calcifications and diffuse susceptibility artefacts on SWI. It is mildly T1 hypointense, moderately T2 hyperintense (outside of the calcific foci) and demonstrates mild internal enhancement. A small pedicle arising from right greater wing of sphenoid is noted. There is no diffusion restriction.
There is no significant intraparenchymal oedema and no other abnormal intracranial enhancement.
There is moderate mass effect on the adjacent right frontal lobe parenchyma with mild rightward midline shift and compression of the right lateral ventricle (especially the frontal horn).
