Male, 62 years old, yearly follow-up for pituitary cyst. A heterogeneously enhancing mass is redemonstrated within the sella measuring 16 mm AP, 15 mm TV and 15 mm CC, without significant interval change in size. Although the lesion appears to be predominantly solid, there are irregular areas of nonenhancing, possibly cystic tissue intermixed, and these areas seem to be smaller than on the prior examination. As before, the lesion extends into the suprasellar cistern mildly but without significant impingement on the optic apparatus. The pituitary stalk deviates toward the left inserting on the apex of the lesion. A mucous retention cyst is evident in the left maxillary sinus.
There has been no significant interval change in the overall size of a sellar/suprasellar mass, though suspected cystic components of this lesion do appear to be smaller.
