Why the radiologist wrote it that way
"Free fluid" is fluid lying loose in the abdominal or pelvic cavity, outside the bowel and organs. After an injury it can mean bleeding; in other settings it can come with infection, inflammation or liver disease. Ultrasound and CT both look for it routinely, especially in emergencies, so radiologists state that it is absent as a clear negative.
Is this good or bad news?
This is the answer a scan looking for internal bleeding, a burst organ or significant inflammation is hoping for. It is often part of an otherwise normal report. One nuance worth knowing: in women of reproductive age a small amount of fluid in the pelvis can be normal, often related to ovulation, and a report may describe "a small amount of physiological free fluid" without concern. That is a different sentence from this one, and is also usually harmless.
What it does not mean
- That the whole abdomen is normal. It answers one specific question; other organs are reported separately.
- That the cause of your pain has been excluded. Many causes of abdominal pain do not produce free fluid.

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
- No acute intracranial abnormalityThe scan found nothing new or urgent inside the skull — no bleeding, no swelling, no sign of injury needing treatment today.
- UnremarkableNormal. There was nothing worth remarking on.
- Mild degenerative changesOrdinary age-related wear in the joints or spine — the kind almost everyone develops, to some degree, as they get older.
- No acute cardiopulmonary processThe chest X-ray shows no new problem with the heart or lungs — no pneumonia, no fluid around the lungs, no collapsed lung, and a heart that looks a normal size.
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.
