Legend Axial FLAIR (left) and T2 (right) images reveal a high signal mass arising in the pineal region and extending forward along the third ventricle. It compresses and displaces the third ventricle to the left. A small amount of edema surrounds the mass.

Legend Additional FLAIR image (left) shows some additional extension to the left of the 3rd ventricle. Sagittal T1 images (right) aid greatly in locating the mass to the pineal region with extension inferiorly along the posterior 3rd and into the tectum of the midbrain.

Legend Clockwise, post gad axial, coronal, and sagittal T1WIs reveal vivid enhancement of this mass. Key words: mri pineal tumor neoplasia
