Case Discussion

Care must be taken in interpreting peripheral areas of delayed enhancement in pituitaries when the endocrinological abnormalities are not well defined. "Elevated prolactin" is common (see elevated prolactin - differential diagnosis) and can be due to many different causes. Similarly, infertility has many causes. 

As such prolactin levels need to be obtained to allow appropriate interpretation.
