Female, 43 years old, with elevated prolactin. Evaluate for pituitary mass. A hypoenhancing lesion is present within the left lateral sella potentially extending into the cavernous sinus. The lesion measures 6 x 6 x 6 mm and has decreased in size from the prior examination where it measured up to 8 mm in diameter. The pituitary gland is otherwise within normal limits. The pituitary stalk enhances normally and deviates very slightly towards the right. No evidence of significant suprasellar encroachment is seen.
Interval decreased size of a hypoenhancing lesion in the left sella which, given the history, would be compatible with a microadenoma.
