Primary intraventricular lymphoma (non-Hodgkin's lymphoma) in a 77-year-old woman.

A. Sagittal T1-weighted MR image (600/15) depicts multiple masses in the hypothalamus, floor and posterior wall of the third ventricle and septum pellucidum (arrows). The posterior lobe no longer shows high signal intensity.

B. Contrast-enhanced sagittal T1-weighted MR image (600/15) shows strong enhancement of the above mentioned lesions and of the superior portion of the fourth ventricle (arrows), indicating lymphomatous involvement. Lymphoma was pathologically proven.
