 Dedicated images through the sella demonstrate diminutive pituitary tissue along the posterior inferior aspect of the sella, consistent with incidental partially empty sella. Glandular tissue measures4 mm in greatest height. Grossly, this appears similar to the prior MRI brain. There is a tiny area of relative hypoenhancement along the right paramedian posterior aspect of the gland measuring 1 mm CC x 2 mm AP x 3 mm transverse (8/9, 7/9). The pituitary stalk lies in the midline, although is likely adhesed to the posterior inferior aspect of the sella as it is placed posteriorly in the AP dimension. Suprasellar cistern, optic chiasm, cavernous sinuses and intracranial portions of the optic nerves appear unremarkable.
Redemonstration of a partially empty sella, with a punctate focus of hypoenhancement along the right paramedian posterior glandular tissue. Please correlate with serum hormone levels for possibility of tiny microadenoma.
