Hello, I'm a 56 year old male. Four years ago I had papillary thyroid cancer with local spread to lymph nodes. It was treated with a total thyroidectomy and removal of affected nodes and subsequent radio iodine treatment. There has been no recurrence. In December of 2019 a nodule on one of my adrenal glands showed up on a CT. It was 1.2cm in size. I had some hormonal tests done and there were no abnormal levels. This month my endocrinologist asked for more blood tests, principally thyroid related tests (TSH, T4, thyroglobulin, etc) but also DHEA-S. All tests were normal except for elevated DHEA-S levels. In the past my DHEA-S levels have typically been between 350 and 400ug/dL. The recent reading was 654ug/dL. The endocrinologist asked for the test to be redone. I did the test again yesterday and the level is still high, measuring 684ug/dL.
I now have to wait for the results of a second CT with contrast that I am trying to organise. It may take weeks for the final result as the insurance company takes a very long time to approve more expensive exams. The endocrinologist said I need to wait to see if the nodule has grown in size but did not offer any more information.
I'm wondering what is the likelihood that this nodule is malignant and also what more tests, beyond the imaging, should be done to prove if it is functional, malignant or not?
