as she has noticed her menstrual cycle has become irregular over
the past 6 months. She has performed multiple home-pregnancy tests,
all of which have been negative. In addition to her irregular
cycles, she complains of a headache and over the past two weeks,
feels as though her vision is disturbed. On further questioning,
she explains that her vision is not blurred; the GP finds
bitemproal hemianopia on examination. She has a recent diagnosis of
hypothyroidism, but no other medical history of note. She takes
levothyroxine daily. She does not take any other medications
or over the counter remedies. She is not on the oral contraceptive
pill. Bloods are sent and she is found to have a raised prolactin
level.
