Axial T2W and FLAIR, and Sagittal T1W images; large right inferior frontal lobe
lesion with heterogeneous signal and a large right posterolateral and inferior
cystic component. Overall peripheral rim of low T2 (and Flair) signal and foci
of high signal on all images. Positive mass effect, moderate left midline shift
and right frontal lobe white matter edema.
Left to Right: Axial Gradient, B0, Diffusion, Apparent Diffusion Coefficient MR images
and non contrast axial CT; large area of blooming artifact, restricted diffusion in
the right posterolateral "cystic" component that demonstrates hypodense attenuation
on CT. Larger area of mass is hyperdense on CT.
Pre-gad axial T1, Post Gadolinium axial and Coronal T1W images demonstrate no
significant enhancement of the lesion.
