There is a large, ill-defined mass in the right frontal lobe with extensive
surrounding edema, causing right to left midline shift. Post gadolinium images
demonstrates thick enhancing rim with mass-like areas of enhancement internally
as well as central non-enhancing regions which likely represent necrotic areas.
Diffusion tensor imaging displays marked splaying, distortion and attenuation
of right frontal white matter tracts.
MR perfusion demonstrates increased rCBV in the periphery and corresponding
mass-likely enhancing region within the mass and lack of perfusion in central
