These results on Bill Kennedy,........, would indicate a pituitary source for
increased ACTH production with a greater than 2-fold gradient before CRH in the
right IPS (but with a normal cortisol) and a many fold gradient post CRH (at
least in the right inferior petrosal sinus sample). If due to an adenoma, it
would appear to drain into the right with a greater than 10-fold gradient
between right and left. The inferior petrosal sinuses were of similar size, and
normal. Obviously, these results must take into account the patient's clinical
scenario, and there are false positives and possible overlap with normal.
So there we have it. Nothing on the AVS yet and no word from Dr. F. While I was sure the IPSS would show something it's still a little of a shock to actually read it. Before, it was all in our mind, now it's positive.
