 There is a 4 mm transverse x 3 mm craniocaudal focus of relative hypoenhancement within the right pituitary gland correlating with the smaller focus of T2 hyperintensity, matching previous abnormality identified on the MRI from 2003 and consistent with microadenoma. Although it appears to be larger, a portion of this is secondary to changes in technical acquisition including dynamic contrast imaging and also interval increase in conspicuity. The infundibulum remains in the midline. There are no suprasellar or parasellar masses and the cavernous sinuses are symmetric bilaterally.
