Legend Axial FLAIR images reveal mass-like signal abnormality involving both gray and white matter of the left frontal lobe with probable extension to the right frontal lobe via the corpus callosum.

Legend More superior T2 and FLAIR axial images reveal the left frontal mass with mild midline shift.

Legend Coronal (left) and axial (right) post gad images reveal no enhancement. The abnormal hypointensity spares the corpus callosum, suggesting that the callosal signal abnormality on the T2-weighted scans may be limited to edema. Subtle subfalcine herniation is seen on the coronal image. Key words: mri tumor neoplasia
