Axial PD (1, 2) and T2 (3): A large heterogeneous suprasellar mass
is hyperintense on PD and isointense on T2. The mass displaces
but does not surround the internal carotid arteries.
Axial (4) and coronal nonenhanced (5) and gadolinium-enhanced (6, 7) images
again demonstrate that the mass is heterogeneous in signal . Minimal peripheral
enhancement is present. The optic chiasm is markedly effaced.
Sagittal T1 images prior to (8) and following (9, 10) gadolinium administration
show erosion of the sella and clivus by the mass.
The time-of-flight MRA shows the hyperintense mass displacing the carotid
arteries laterally and elevating the anterior cerebral arteries. Phase contrast
MRA shows no flow in the mass and the mass is hypointense..
