Enlarged lymph nodes ab ct scan after colonscopy found mild colitis. Had rectal bleeding daily for 1 month. Now gone. Going for 6/mo check. Lymphoma?

Not necessarily: There are many reasons for enlarged lymph nodes; most common is reaction to infection/inflammation which maybe your case but they can also enlarge in reaction to cancer nearby and in cases of lymphoma. These possibilities shluld be sorted out after colonoscopy and biopsy of any colon lesions ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! The image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Swollen jugular lymph nodes, 5mm per CT scan. Has been swollen for over 6 months. Goiter. What's going on?

Cervical LN caution!: Many inflammations can cause large cervical LNs. LN over 10 mm is generally abnormal. Danger of cervical LN enlargement is that such nodes frequently harbor head and neck neoplasms. If it persists may need biopsy. ...Read more

Indeterminate but concerning lymph nodes in the mesenteric lymph nodes...In a CT scan report. Aslo 2 cyst near ovary. Doe this mean cancer.

Not necessarily: Why was the ct done in the first place? Slightly enlarged lymph nodes in the mesentery are not specific for cancer. They may be normal variant or inflamed nodes. Cysts in the ovary or near? If simple cysts unlikely to be malignant again. However, one's symptoms that led to ct scan should be the context in which one reviews imaging or lab results. ...Read more

Would my doctor be able to see whether my lung cancer has spread to my lymph nodes on a CT scan?

Would my doctor be able to see whether my lung cancer has spread to my lymph nodes on a CT scan?

Yes, but with just a: Little more accuracy than a coin-flip based on size. Ct's miss small things, and falsely label benign things cancer. Proving nodal positivity is helped with pet scans, endoscopic ultrasonography with esophagoscopy or bronchoscopy, and sometimes surgery. Why the fuss? If nodes are +, the role of surgery is limited, and surgery is no picnic, and despite trying to prove its benefit, we're not sure. ...Read more

Swollen lymph node under jaw CT scan neg how do you know if you have Pathogens left behind the bone? Been swollen for 2 months

Good questio: If a radiograph does not visualize either infection or tooth fragment, energy testing will identify and quantify the presence of infection. Appropriate detoxification and/or surgery will resolve the infection and swelling. ...Read more

Multiple small subcentimeter bilateral axillary, mediastinal and hilar lymph nodes are noted on CT Scan what does this mean?

Just what it says: Lymph nodes, located where they are supposed to be, visible on the CT scan and at a size that is generally considered normal. Taken out of context, it is impossible to tell you anymore than this. But even in the context of some known disease, these likely mean nothing. ...Read more

Can endometrosis cause mesternic and retro-penal lymph nodes to show in a CT scan. The radiologist noted them but did not say they were enlarged.?

See below: Non-enlarged lymph nodes seen on a ct scan are likely just to be a normal finding in most anyone. Would not seem to be related to endometriosis to me. Ask the doctor who ordered the ct scan to review with you what the significance of the radiology reported findings means for you. ...Read more

Dr said mono. Left supraclavicular lymph node swollen several weeks. Had ct scan, all ok. Worried as read those lymph node are bad when swollen.

Biopsy Virchow's Nod: The L supraclavicular node is particularly worrisome. Due to the drainage of the lymphatic system, Virchow's node (as it is known) is commonly the first node that enlarges in cancers of the chest, abdomen, legs, & left arm. Scans can be negative & miss cancer, especially since they are anatomical scans, not functional ones (small cancers can be missed). Biopsy or PET recommended. TTYD or HT Prime. ...Read more

My father has metastatic melanoma, 1 lymph node involvement. Pet scan and CT scan shows no other metastasis at this time. Does this mean he is cured?

My father has metastatic melanoma, 1 lymph node involvement. Pet scan and CT scan shows no other metastasis at this time. Does this mean he is cured?

Melanoma...: Melanoma is a very tricky disease and must be followed closely. It can metastasize to odd places. It is good news that only 1 lymph node is seen on pet/ct rather than many lymph nodes but one should note that micrometastases or very small lesions may be below the resolution of pet imaging. ...Read more

Which is better, MRI or CT scan, when trying to detect what's the nature of a cervical swollen lymph node? Is a CT scan of neck a lot of radiation?

Clinical issue: Choice of imaging study will depend upon what is being looked for. The best way to approach finding out what this is, is to biopsy it, but the diagnostic approach may be to assess first the extent of involvement and other areas which may also have structural abnormalities. Ct carries a fair amount of radiation but may be necessary under these circumstances, and one ct not likely to be harmful. ...Read more

Hi. If one has lymphoma and does a neck CT scan of swollen lymph node, would the CT scan show an abnormality that leads to a biopsy or can it miss it?

Hi. If one has lymphoma and does a neck CT scan of swollen lymph node, would the CT scan show an abnormality that leads to a biopsy or can it miss it?

No test perfect: But a contrast enhanced ct scan of the neck performed and interpreted well should see any enlarged lymph nodes.

Unfortunately, sometimes disease is located in lymph nodes that are normal in size. That is why for lymphoma, pet/ct is often performed for restaging.

See your doctor and decide what further workup is needed. ...Read more

Hi. Had a ct scan results say I have multiple partially calcifiedmediastinal lymph nodes measure up to 28mm. What does this mean?

It means: You probably had a previous inflammatory/granulomatous process that caused it. For example, histoplasmosis, TB, sarcoid. Occasionally treated lymphoma, certain metastases, and certain dust exposures can do it. It is possible that the cause is not clinically relevant at this point, but speak with your doc about what this finding may mean in your case. ...Read more

Ct scan results "numerous lymph nodes in right and left neck. Stable in appearance" What does this mean?

Important facts: To fully answer, more details are needed, but this is what I know:
You had a CT done of your neck to follow-up on the finding of some lymph nodes in your neck.
Usually this is done to make sure someone doesn't have cancer or that someone who you know does have cancer does not have progressive disease.
In your case, it is reassuring to find a "stable" appearance but you must meet with your doctor. ...Read more

What could cause reactive lymph nodes in both inguinal regions (as noted on a CT scan)?

Lots of things: A reactive lymph node is a pathology finding, that is something you can diagnose with a biopsy, but not with a ct scan. There are lots of lymph nodes in the inguinal region, and a few slightly enlarged nodes is not a big finding. If your doctor thinks more needs to be done, a biopsy might be needed. ...Read more

Can you have a lot of sigmoid lymph nodes swell up if diagnosed with diverticulitis with a ct scan?

Can you have a lot of sigmoid lymph nodes swell up if diagnosed with diverticulitis with a ct scan?

Absolutely: Often diverticulitis has a chronic element, which allows adenopathy.
Earlier (acute) signs are the "misty mesentery" &/or smudged pericolonic fat which is inflammatory change in the fatty tissue that suspends the sigmoid. Also we look for free fluid and esp. Free air (perforation).
Care must be taken to exclude inflammatory change near a cancer so F/U scan/colonoscopy is often done after a while. ...Read more

Would a CT scan be able to tell you if your appendix or lymph nodes next to your appendix are infected?

Would a CT scan be able to tell you if your appendix or lymph nodes next to your appendix are infected?

Probably helpful: A ct scan can help identify the appendix and/or nearby tissues. It can give an idea about swelling or inflammation. The only limitation is that it is possible for the appendix to not be visualized. Rare occurrence, but, leaves you wandering what to do next. It's worth being done. ...Read more

I have IDC and ct scan said 2 12mm indeterminate lymph nodes found in same area. Lumpectomy in two days. Do the those lymph nodes have to be removed?

Maybe: Surgeons will often use injection of a small amount of a radioactive material to identify the lymph node that drains that area of the breast. This is called a Sentinel Node localization and biopsy. This procedure has been shown to be efective in identifying spread to the Lymph nodes.

Speak to your surgeon about this procedure. ...Read more

My mom has 2 small lymph nodes, showed up in her X-ray and CT scan. But she doesn't feel anything, she's very healthy. Should we worry? Is there a cure?

Talk to your doctor.: Small ln are actually very common and may be normal. Can't really say with this limited info. Where exactly were the ln? How small are they? Is there a history of some disease or symptoms which could cause ln swelling? Why did we get the cxr to begin with - was there a suspicion of something? Your doctor already knows the answer to these and can tell you if you need further testing or not. ...Read more
