What does “Pulmonary nodule” mean on a radiology report?
A small round spot in the lung — usually well under an inch across, and in most cases harmless.
Why the radiologist wrote it that way
Nodules turn up constantly on chest CT, which is sensitive enough to find very small ones. The radiologist records size, position and whether it is solid, because those features determine whether anything needs doing.
Is this good or bad news?
The great majority of small lung nodules are benign — old healed infections, small scars, clusters of normal tissue, tiny lymph nodes. Because a minority are not, radiology has well-established published guidance on which sizes and appearances warrant a repeat scan and when. If your report recommends a follow-up interval, that recommendation is the system working normally, not a signal of suspicion. Comparing with any older scan is often the fastest way to settle it: a nodule unchanged over years is reassuring in itself.
What it does not mean
- Cancer. Most nodules are not, and small ones very often are not.
- That a follow-up scan implies suspicion. Interval follow-up is the standard protocol.
- That it is new. Without a prior scan there is no way to know how long it has been there.

One phrase is not the whole report
What this sentence means for you depends on everything else your report says. Radily reads the whole thing and explains it in plain English — and can talk you through it on video, so you are not reading medical language alone.
Other phrases on your report
- Cannot be excludedThe images are not able to completely rule this out — which is a statement about the limits of the scan, not a suggestion that it is likely.
- NonspecificThe finding is real, but its appearance is not distinctive enough to say what is causing it.
- Small pleural effusionA small amount of fluid has collected in the space between the lung and the chest wall.
- Hepatic steatosisFat has built up in the liver — commonly called fatty liver.
This explains how a phrase is commonly used in radiology reports. It is not a diagnosis, not a reading of your scan, and not medical advice. Only your doctor can tell you what your own report means.
