CASE 34: 43 y/o male with altered mental status

Patient had altered mental status mainly behavioral changes and abnormal hesitation in regular activities. CT scan was abnormal but inconclusive. There was a focal hypodensity  in right frontal lobe but with no ischemic characteristics. Rest was unremarkable. We did a contrast enhanced CT scan to see if it showed an abnormality.

Here are the relevant images of the contrast enhanced CT scan:

With a diagnosis in mind, we conducted an MR:

Axial FLAIR

T1 coronal post gad

Pretty clear diagnosis. Findings?...later, the conclusion.
