Common causes

- Less common but more serious causes depending on the imaging context
When doctors worry
- The report says the finding is suspicious, enlarging, obstructive, or aggressive
- The imaging pattern is indeterminate and follow-up is recommended
- Symptoms, lab results, or cancer history make the finding more concerning
Typical follow-up
- Compare with prior imaging when available
- Use a targeted follow-up scan or specialist review when the report recommends it
- Interpret the finding with the rest of the report instead of the slug alone
