Legend Axial FLAIR images demonstrate two round areas of increased signal intensity in the periventricular white matter suspicious for mass lesions. Focal hyperintensity is also present in the right occipital lobe. Additional small hyperintensities in the frontal lobes probably represent chronic ischemic change.

Legend Coronal T1, pre and post contrast, upper left and right images, demonstrate a small amount of hemorrhage associated with the left periventricular mass. A third enhancing mass is noted in the cerebellar midline with mass effect upon the adjacent fourth ventricle.

Legend A fourth heterogeneously enhancing mass is seen in the right occipital lobe. Key words: mri tumor neoplasia
