Female, 46 years old, history of small pituitary adenoma now with persistent headache. Assess for growth of lesion. A lesion in the right posterior aspect of the pituitary gland seen on the 2011 examination remains much reduced in size and similar to that noted on the more recent examination from 2014. No discretely measurable lesion is seen. Rather, the right posterior aspect of the pituitary is mildly heterogeneous in T2 signal and pattern of enhancement.The remainder of the pituitary gland is within normal limits. The pituitary stalk sits at midline and enhances normally. No suprasellar lesions are detected. No abnormalities of the visualized optic apparatus are seen.
Stable appearance of the pituitary gland with residual heterogeneity of the right posterior aspect of the gland representing the site of a previously larger lesion.
