First of all I'd like to say that this site and its forums have been quite useful for me. Thanks to everyone who contributes and devotes their time to helping others!
My dad (72) was diagnosed in October with stage IB squamous lung cancer. Two weeks later he had upper right lobectomy. Histology read: poorly differentiated (G3) squamous cell lung cancer with massive necrosis. No lymph nodes involved. Doctors recommended adjuvant radiotherapy to the mediastinum, just in case and did 40Gy.
A post-surgery CT scan indicated suspicious bilateral adrenal masses 3.6 and 3.8 cm. The pre-operation scan indicated these adrenal masses as adenomas. Both pre- and post-operation CTs were done without contrast. (PET was not suggested by any of the doctors).
Now, 3 months after radiotherapy we did a CT with contrast which showed 3.3 and 4.8 cm masses in the adrenals. One of which has lower attenuation segments (the larger one).
Another important note is that over 1 year ago my father had an abdominal CT with contrast in connection with some kidney stones and the two masses in the adrenals were reported there as 3.2 and 4.8 cm adenomas.
My question is, is it more than likely these are metastasis? Especially given the CT performed over a year ago showed them too? Wouldn't they have grown considerably more, if they were? One oncologist advised starting chemo, indicating the lower attenuation areas were probably necrotic zones, but we will consult another one to get a second opinion.
I would appreciate any thoughts on the matter. Thank you once again.
