Thanks for choosing Doctorspring.com From the MRI I do see a pituitary microadenoma. Your endocrinologist will be the best guy who can suggest you whether to continue medical management or is there a need for surgery. Pituitary adenomas are non cancerous, ( 0.1-0.2 % incidence ), and they are also non-invasive, mostly not capable of causing a lot of substantial damage. Risk of surgery for patients with Cushings is high with relatively low success rates... Regards 
Patient replied :
Can you leave a comment on the pictures that have a microadenoma? Because the radiologists who took these said there was no tumor.

In the sagittal images of the pituitary fossa, the whole of bright structure is the tumour. The normal pituitary gland is dark in color.
I can describe better if I have coronal images, early contrast and delayed contrast images of the pituitary.

Patient replied :
The mri album earlier had early contrast and delayed. They injected me twice, once between the scan & another during the scan with galdonium.
I think you are referring to these two pictures I marked with red circles?
Thanks for writing to us again.
Yes. The red circle which you have marked in the attached images is the one which points to the pituitary tumour. Patients with cushing's are very poor and high risk candidates for surgery. The line of treatment will be best guided by a endocrinologist. Kindly consult your endocrinologist, so that he can start the treatment regimen soon. In my opinion, its best to control your symptoms medically, since medicines can block the hormones that's been produced in your body, and it will lead to relief from your symptoms. Hence the Endocrinologist opinion is recommended.
Based on his opinion, and treatment regime we can decide if radiation might be required in the future. Also just to reinforce these tumors are non cancerous. That's the good part. Kindly get an opinion and get back to me for additional information.
