Legend Axial T2 images reveal a high signal mass involving gray and white matter in the left temporal lobe. The uncus and medial temporal lobe have migrated medially to compress the midbrain and ambient cisterns.

Legend Additional axial T2 (left) FLAIR (right) images again reveal the large mass involving gray and white matter, with extension to the insular cortex, external capsule and putamen.

Legend A pre gad coronal (top left) with post gad coronal and axial images demonstrate no clear enhancement but the low signal center suggests cyst formation. The sylvian fissure and MCA insular branches are displaced superiorly. Key words: mri tumor neoplasia
