Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
From the case:
Glioma (MR spectroscopy)
MRS

MR spectroscopy of a high-T2 signal expansile lesion of the insular cortex, known to be a glioma, shows a raised choline peak with a depressed N-acetyl aspartate peak.
Increased choline and choline/creatine ratio and decreased NAA levels.
