What does "lymphadenopathy" mean on my CT or ultrasound report?
Short answer: enlarged lymph nodes were seen on your scan. "Lymphadenopathy" is the medical term for lymph nodes that are bigger than expected. Lymph nodes are small, bean-shaped filters of the immune system found throughout your body — in your neck, armpits, chest, abdomen, and groin.
What it usually means on your report
Lymph nodes enlarge when they're doing their job: fighting infection or responding to inflammation. A cold, a recent vaccination, a skin infection, or an inflammatory condition can all cause nearby nodes to swell temporarily. That's why radiologists often describe the nodes' size and appearance — features like a preserved fatty hilum (the node's normal center) and normal shape tend to suggest a benign, reactive process.
The important context: imaging alone can't say why nodes are enlarged. A CT or ultrasound shows size, shape, and location — it can't examine the tissue. That's why reports often recommend "clinical correlation" (your doctor matching the finding to your symptoms and history) and sometimes follow-up imaging or a biopsy if the cause isn't clear.
What it does NOT mean
- It does not mean cancer. Infection and inflammation are far more common causes of enlarged lymph nodes. The word itself just means "enlarged nodes" — it says nothing about the cause.
- It does not mean the radiologist knows what's causing it. Determining the cause usually requires your clinical picture and sometimes tissue sampling.
- It does not mean every enlarged node needs a biopsy. Many are simply monitored to confirm they shrink back down.
When to ask your clinician
- "Could my recent [illness/vaccination/infection] explain these enlarged nodes?"
- "Do these nodes need follow-up imaging, and when?"
- "What symptoms should prompt me to come back sooner?"
This is a plain-English explanation of terms, not medical advice. Talk to your clinician about what your results mean for you.
