I am interested in people’s experience. I have done lit search and haven’t answered my questions. I found a mass left adrenal in 12 yr old mixed breed. the surgeon removed left adrenal and left kidney since vascular invasion found there was also invasion of surrounding tissue planes and perirenal bleeding. The histopath adrenal cortical carcinoma with infiltration into renal vein.It is one month post op. The remaining adrenal gland was scanned last week by internist and me today. There is some discussion about whether it is normal. When to expect hypertrophy? how much hypertrophy if it occurs? etc. the patient today was not still so video not taken. I have included images anyway.the surgeon felt at time of surgery the right adrenal was normal.
