Differential diagnosis means the list of possible explanations doctors are considering for a finding or symptom.
This is not a symptom itself. It is a way of saying that more than one condition could explain the problem seen on the scan or described by the patient.
Imaging helps narrow the list by showing patterns, location, size, spread, and associated features that make some causes more likely than others.
Radiologists often give a differential diagnosis when a scan finding is not specific enough to point to only one explanation.
The next step may include follow-up scans, blood tests, biopsy, treatment, or specialist review to confirm which explanation is correct.
This entry explains the word. If it appeared on your report, the next step is getting that report interpreted for your case.
