 Compared to 7/1/2015 there is slight increase in prominence of the hypoenhancing pituitary lesion involving the left anterior aspect of the pituitary gland measuring 7 x 7 x 7 mm, previously 7 x 6 x 6 mm in the AP, transverse, and craniocaudal dimensions. Lesion is isointense on T1 and hyperintense on T2-weighted sequences. The pituitary stalk remains midline. There is no suprasellar extension or optic chiasm abutment. Cavernous sinuses are unremarkable. Limited evaluation of the visualized brain parenchyma is unremarkable.
Stable to minimal interval increase in size of hypoenhancing nodule involving the left anterior aspect of the pituitary gland which is favored to represent a microadenoma. T1 hyperintense blood products within the sella seen on remote prior studies are no longer evident.
