Questions??????

  So the last post was about the new symptom I have ( drooping face at times, it comes and goes)….So I got my MRI scheduled, went to it....during the MRI my left side felt weird I can't really explain it...like somewhat it wasn't there of in the middle of my head...I guess that's how I would explain it...at times my whole left side felt like that...or like it wasn't there....now wait for the results...
 by the way the MRI was mainly focused on my ear cannel . Neurologist thought that maybe I could have a inner ear inflammation...t( he didn't even look in my ear...)
   So I got the MRI on Wednesday of this past week...The doctor called me , himself... with the results of the MRI...( he is hard to understand at times)….he said something about ordering another MRI at least that's what I got out of it...I was so shocked that HE ( himself) called me with the results..So I go to the hospital login and log in...and find that I need another MRI focusing on the pituitary gland..( I said which is hard to pronounce)...So I then see that the results of the MRI are in..
 The results are as follows: Abnormal signal in the left lateral Pituitary gland. predominantly hypointense on T1 and hyperintese on T2 with some internal heterogeneous signal possibly representing calcification or blood products...lesion measures 8.5 mm craniocaudad x 5 mm transverse x 6.9 mm Ap. the remainder of the pituitary gland stalk and optic chiasm unremarkable...
Impression  is Chronic small vessel ischemic changes and lesion in left lateral pituitary gland. Complex cyst cannot be differentiated from neoplasm....( now that is a mouth full and a lot of words I don't understand)...I know that hypo means less and hyper means more...and internal means inside..so of course I google all the words I don't understand and google the pituitary gland...
   Now the questions I have...Ok I had a MRI back in September Why didn't show up then...considering the how big it showed up on the MRI last week...?...Has this been the my problems all along?...is this why I have hypothyroid issues?...so many questions...and the one that is strong Is this Cancer?...and what needs to be done...What options do I have for this? Do I need an operation?...so many questions...I just wonder why it wasn't seen on the MRI I had in September...

well this is where I leave ya with all of these questions....
