Female, 25 years old, known pituitary adenoma, follow-up exam. The size and morphology of the pituitary gland are stable and within normal limits. The gland measures no more than 7 mm in height. Signal characteristics and pattern of enhancement are slightly heterogeneous. However, no definite focal lesions are detected. At most, there may be a 3-mm focus of slightly increased T2 signal within the midline inferior gland (see image 8 of series 501). This finding is not appreciated on the prior examination, and there is no clear correlation of this finding on post contrast images. The pituitary stalk enters gland at midline and enhances normally. The suprasellar cistern is free of lesions. The visualized optic apparatus is unremarkable.
Stable examination with no definite focal pituitary lesion seen. A small focus of slightly increased T2 signal within the midline inferior gland is of uncertain significance and may be artifactual given that no correlation for this finding is seen on other sequences or on the prior study.
