MKSAP 16 question:
55-yo awaiting kidney transplant (ESRD per lupus). Kidney ultrasound reveals a complex-appearing mass suspicious for a renal neoplasm in the right kidney.
Which of the following is the most appropriate imaging study to perform next?
A) CT with contrast (51%) [correct answer]
B) Intravenous pyelography
C) MRI with gadolinium
D) Positron emission tomography (30%) [wrong answer that I chose]
So I understand that CT is the better radiological modality to characterize said mass (really what you might need here is a biopsy, but that wasn't an answer chioce). But really, what's CT going to tell you? That you have a very suspicious mass that looks like cancer. Don't you already have this info from the ultrasound?
In the context of a patient awaiting transplant: isn't the more pertinent conern that of distant mets? That's why I chose PET. If PET is positive in other organs, that might take her off the transplant list. If PET is negative, she can have a nephrectomy and proceed with transplant!
