Male, 74 years old, with acromegaly, follow-up pituitary microadenoma. A hypoenhancing, T2 hypointense mass is evident within the anterior aspect of the sella measuring 10 mm transverse, 12 mm AP and 12 mm CC. There has been no significant interval change in the size or morphology of this lesion when compared to the prior exam.As before, the lesion extends into the suprasellar cistern and may very slightly contact the optic chiasm. No convincing evidence of cavernous sinus involvement is seen.On limited views of the brain parenchyma, scattered small foci of white matter T2 hyperintensity are redemonstrated appearing grossly similar to the prior exam, a nonspecific finding which may be related to microvascular ischemic disease.
