What to Do With the Incidental Finding Nobody Was Looking For
Imaging reveals more than anyone asked for. How physicians communicate, track, and decide on incidental findings shapes patient anxiety, safety, and the downstream cost of care.
The CT was ordered to look for kidney stones. It found one. It also found a small nodule at the lung base, a subcentimeter lesion in the adrenal gland, and a line recommending follow-up imaging for both. The patient came in for flank pain and is now leaving with three problems, two of which may never matter and one of which might.
Incidental findings are a system problem
As imaging becomes more sensitive and more common, incidental findings have become a routine part of practice. The challenge is not identifying them. Radiologists do that well. The challenge is making sure each finding is communicated, weighed, and either followed or deliberately set aside.
These findings often fall between clinicians. The emergency physician who ordered the scan may assume the primary care physician will handle follow-up. The primary care physician may never see the report. The patient may not remember being told.
Decide, then document
Professional societies, including radiology organizations, publish recommendations for managing common incidental findings, and many radiology reports now reference them. These are helpful starting points. They still require clinical judgment about the patient's age, comorbidities, and goals. A finding that warrants surveillance in a healthy middle-aged patient may not warrant it in someone with limited life expectancy.

Whatever you decide, make the decision visible.
- State the finding and the plan in plain language in the note.
- Name who is responsible for arranging follow-up, and when.
- If you are choosing not to pursue it, say why and record that the patient was part of that conversation.
- Use your record's task or reminder features for surveillance that is months away, rather than relying on memory.
Talk about it without alarming
How a finding is described shapes how a patient carries it. "We found a spot on your lung" lands very differently from "The scan showed a very small nodule. Most small nodules like this turn out to be harmless, and the usual approach is to repeat the scan later to make sure it stays the same." The second version is honest, specific, and gives the patient a plan instead of a fear.
Patients increasingly read their reports through online portals, sometimes before their physician does. That makes it worth anticipating questions and reaching out first when a report contains language that sounds more frightening than the finding is.
This week, look at how your practice tracks follow-up imaging recommendations. If the honest answer is that it depends on someone remembering, that is the gap to close first.
