Though it is not the norm, it's also not uncommon for me to disagree with a radiologist's interpretation of a scan. Radiologists are very thorough and they don't typically miss much but the scans don't tell the whole story. Pixels that show up on a computer screen after a CT or MRI only represent findings inside the body. But the images aren't always perfectly clear and there is a fair degree of "interpreting" that goes on when reading films.

As a surgeon, I have two advantages over a radiologist when it comes to interpreting films on my patients: 1) I have actually seen and examined the patient and therefore have more insight about the severity of the problem and how it affects the patient; and 2) In doing surgery, I can compare the findings on a scan with what is actually going on inside the body and how patients with those findings respond to treatment/surgery.

There is a reason why many radiology reports end with the phrase: "Please correlate clinically." It is an admission that the CT or MRI is not the patient and the significance of any finding (or lack thereof) can only be ascertained by knowing what is actually going with the patient.

That being said, just ask your surgeon about the discrepancy.
