Hello everyone,

i just came back from the radiology and I had an mri done for the pituitary prolactinoma because I have a high prolactin in my blood test.



My results state that I have a pituitary gland measuring 5mm and most consistent with a microadenoma. It also states that I have a giant cisterna magna or arachnoid cyst which measures 4cm.



The impression also stated:

1. Mri finding most consistent with a microadenoma in the right side of the pituitary gland which measure 5mm.


2. Suspected arachnoid cyst versus giant cisterna magna in the posterior fossa with a measurement of 4cm.



I am concerned about the results and I thought I could have someone explain to me the finding in simplest terms. I hope it isn't anything to worry about. Thank you
