what does this mri results mean?
I am so glad you have had good health.
MRIs work with magnets - so just for your future information, anytime you get contrast with different machines, they are all different types. MRIs do not require any radiation and the contrast used is not radioactive but is a material that is metallic and can be passed out in urine but the metal helps things light up for a short time. If you have questions, ask the tech and they should explain about radiation or not - but MRIs are very safe.
The pituitary sits in a fluid filled bone pocket - sort of like one of those chocolate covered cherry things - the cherry sits in goo and the outside is hard. Now, what the doctors found with you is that they cherry/pituitary cannot be seen well and all they can see is the CSF (cerebral spinal fluid)/goo. That is empty sell. CSF appears black on MRIs and you cannot see behind it and you don't know what is going behind it.
So your doc ordered another MRI to look at it - normally a good pituitary MRI is with and without contrast. So that is why your doc did not discuss it probably.
Now the second MRI showed a bit more as it focused in on the pituitary. Now they can see the pituitary is squished (not a technical term) and they may be able to see a lesion there but they are not sure. However, the lesion that they see is rather large... it is just under the level of macroadenoma (over 10mm) - but it a micro-adenoma (under 10mm).
The next step is for you to get a lot of lab testing. You need to find out if/how the lesion is effecting you. You may not think you have vision issues - but pituitary usually take it away from the sides so it can be subtle at first.
Other symptoms can vary a lot from healing issues, bone issues, depression/mood issues, sleep problems, pain, fatigue, etc etc - they symptoms can vary by type of lesion and if the symptoms are caused by mass effect or by hormone. It will have to be monitored to see if you need surgery or medication to resolve the lesion.
I had the surgery as have others here - while it seems very scary as long as you have an experienced surgeon (that is crucial), you should be fine.
