I have just found out my daughter aged 31 has had a catscan, then mri with and without contrast resulting in the findings of a 3mm cyst in her pituitary gland. 10 years ago they found she had had bleeding in the brain from the pituitary gland. She is a lactating mother. I was searching for some knowledge and found Rathicke . Her symptoms have been a dull ache in the head, dizziness and she has almost passed out a few times. This concerns me as she is a nurse and works with newborns as lactation consultant. We are still waiting for the PCP to get back to her.
Hello, I will suggest you to look for some other causes of these symptoms as it's a very remote possibility for a very small pituitary cyst (a 3 mm cyst). Mild headache dizziness and feeling of passing out needs work up like checking her blood pressure, electrolyte (sodium potassium magnesium and calcium levels) and then correlating it to a primary disease of a Chat Doctor.  But this all needs a careful detailed history and physical examination. Hope I have answered your query. Let me know if I can assist you further.
