 The posterior pituitary hypoenhancing lesion seen on prior exam has decreased in size. When measuring the hypoenhancing area alone, the lesion now measures 11 x 8 mm on coronal image 8 of series 7 (compared to 14 x 10 mm previously), and 5 mm AP on sagittal series 8 image 5 (compared to 8 mm previously). There is mild encroachment upon the suprasellar space without significant mass effect on the optic chiasm. There is no significant deviation of the pituitary stalk. The cavernous sinuses enhance symmetrically without evidence of mass. There is no invasion into the sphenoid sinus. There are no other foci of suspicious enhancement in the imaged brain.
Mild interval decrease in size of hypoenhancing pituitary mass.
