Ovoid sharply marginated mass in the lower right part of adenohypophysis with low signal on T2-weighted and iso-slightly low signal on T1-weighted images. Laterally and slightly upper from the mass - low intensity on T1-weighted and isointense on T2-weighted images lesion, less than 4 mm in diameter. The latter is taking up contrast material slower, than anterior pituitery, which is consistent with microadenoma.
