Lymphocytic infundibulohypophysitis in a 43-year-old man.

A. Sagittal T1-weighted MR image (500/25) depicts an isointense mass comprising the hypothalamus, the pituitary stalk, and the pituitary gland (arrows). The posterior lobe no longer shows high signal intensity.

B. Contrast-enhanced sagittal T1-weighted MR image (500/25) shows strong enhancement of the mass (arrows). Lymphocytic infundibulohypophysitis was pathologically proven.
