restlessangler said:I had an MRI done back in month 9, and then last week I had this pituitary MRI based on those previous results:
On the pituitary MRI—viewed in three planes, both natively with T1 and T2, and post-contrast—the pituitary gland itself is normally positioned with regular shape and size, though there is a cystic formation measuring 7.7x4.9 mm located posteriorly on the left. The pituitary stalk is regular and shows no resistance.
The pituitary exhibits a homogeneous, normal structure, with the aforementioned cystic formation noted on the native slices at the posterior aspect.
The parasellar and suprasellar regions show no changes. The optic chiasm and cavernous sinus appear normal.
Following the administration of contrast, the pituitary shows homogeneous enhancement, except for the described cystic formation, which does not take up the contrast.
I know I’m just a layperson, but it feels like this scan was totally unnecessary since nothing "new" appears besides the dimensions. Am I wrong here, or did the doctor who wrote this miss the mark? Why even do this second scan if nothing new was discovered—unless I'm right about the cyst being on the posterior side while the first scan placed it in the adenohypophysis area?
I'm honestly so disappointed by all this..
Is there anything actually new in these results?
He didn't miss the mark.
When you undergo a pituitary MRI (or really any specific imaging, for that matter), you have to understand what the goal is—what are we trying to prove or rule out?
If there is a suspicion of a microadenoma, a pituitary MRI is performed specifically to confirm its presence. While a standard brain MRI might pick it up, it can be unreliable because the pituitary is such a tiny structure; therefore, you need a targeted, specialized view. It also allows doctors to see how it relates to surrounding structures, which is absolutely vital if surgery ever becomes necessary.
So, the objectives are to:
1. Describe the pituitary, check for pathological changes, and see how it reacts to contrast—
which is described in your report 2. Describe the appearance of the infundibulum—
which is described in your report 3. Describe the appearance of the optic chiasm—
which is described in your report 4. Describe the appearance of the suprasellar region—
which is described in your report 5. Describe the appearance of the cavernous sinus—
which is described in your report 6. Note any potential abnormalities in the sphenoid sinus, meninges, etc.

Nothing "new" was found, but one shouldn't expect something entirely different with a microadenoma—the whole point was simply to confirm what was already seen on the brain MRI, for the reasons I mentioned above.
