Axial T2 (left) and FLAIR(right) images demonstrate a large mass with both solid and cystic
components, causing mass effect on the inferior frontal lobes, bilaterally. Note the
posterior position of the anterior cerebral arteries.
A pre-gad sagittal T1W image (left) reveals mostly hypointensity with a posteriosuperior
crescent of high signal material. The sagittal plane helps locate the lesion in the suprasellar
and subfrontal regions.
On axial and coronal postcontrast T1WIs with fat-suppression, note the heterogeneous enhancement
of the solid component of the lesion. The hyperintense material does not suppress, ruling out
fat and making it more likely to be proteinaceous fluid or subacute hemorrhage.
