Yes important: Reticule nodular patterns are important for they imply a particular type of infection. You should have this investigated with your primary care doctor. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

After diagnosis with C.T scan Abdomen results were liver cyst - small left lung base nodule, my mother have pain symptoms every four days pls advice?

May not cause pain: Liver cysts are usually benign fluid filled structures. There are may causes for lung nodules including lung cancer and therefore usually requires follow up. Neither is usually painful. ...Read more

I have diagnosed with a 3 mm lingular nodule probably representing granuloma. Mild fibrotic changes at the left lung base. Is this something I should worry about?

I have diagnosed with a 3 mm lingular nodule probably representing granuloma. Mild fibrotic changes at the left lung base. Is this something I should worry about?

Need to follow up: Follow up checks with X-Ray /CT scan is advised to be certain that it does not grow in size. Most likely it is benign in which case it will remain inactive and not grow in size. Unless you have watched/monitored it for the next 2-3 years, there will remain some concern that it could be an early form of lung Cancer although it is not very likely to be. ...Read more

Saw a 3 mm nodule during a CT scan at the base of my left lung. What could it be?

From nothing: To an early something. The anxiety you are experiencing is given as a main reason to not do screening ct's in smokers. 3 mm is too small to worry about. If it were me, i'd re-ct in 6 months to a year to check change in size. You can google the nlst - national lung screening trial. Do you smoke? Time to stop if yes. Good luck. ...Read more

6mm nodule left lung base pleural surface and faint 6mm nodule on left lower sub pleural lobe found from CT. Enlarged heart found on right side. Also very slight alveolitis found in right upper lobe. ?

Nodule: A 6mm nodule is a relatively common finding. Many times these are benign resulting from old infections or exposures. It becomes more worrisome in a smoker, and regardless should have a follow up cat scan in 3-6 months. ...Read more

A very faint subpleural nodular density in the left lower lobe posterolaterally noted on CT Scan along with minor nodularity to posterior lung bases?

A very faint subpleural nodular density in the left lower lobe posterolaterally  noted on CT Scan along with minor nodularity to posterior lung bases?

Do they give a size: for the "subpleural nodular density"? There are a litany of potential causes, from chronic to acute, from inflammatory to neoplastic, from no concern to worrisome. More specific info on the nodule and any relevant clinical history would help narrow it down. ...Read more

Got a 2cm nodule in my left lung. Can it be a hytadid cyst?

Got a 2cm nodule in my left lung. Can it be a hytadid cyst?

Lung nodule: The only way to find out for sure what it is is to do a biopsy. Depending on what the radiologists impression of the lung nodule is, we sometimes elect to do interval or followup imaging to see if the nodule is stable or not. Please discuss with the doctor who ordered the imaging test what the plan of action is. Best of luck. ...Read more

What is nodule 10mm in left lung mean?

What is nodule 10mm in left lung mean?

Many possibilities: This is a "spot" in the lung where there's a concentration of solid tissue. The spot may represent a focus of past or present immune activity against a particular germ such as TB or histoplasmosis, or a growth of some type. Most turn out to be harmless, but listen carefully to your doctor(s) re the best and safest way to evaluate the nodule. ...Read more

Hi Dr. I am 34 years old male , non smoker I took chest radiograph before 2 weeks I found that I have lung nodule 6*6mm In my left lung ,thanks?

Hi Dr.
I am 34 years old male , non smoker
I took chest radiograph before 2 weeks
I found that I have lung nodule 6*6mm
In my left lung ,thanks?

CT follow-up: Get a CT scan if not done yet. Isolated lung nodule of 6.6 mm is too small to be detected by PET-CT, and also too small to biopsy at this time. Your risk for primary lung cancer is relatively low given your young age and nonsmoker status. But I suggest you to see a lung doctor for opinion and CT follow-up. In addition, what did your MRI abd show? ...Read more

In 72'-74', I was on a U.S Navy ship, which was full of asbestos. In 05', I was diagnosed with that left lung nodule. May this have caused my nodule?

In 72'-74', I was on a U.S Navy ship, which was full of asbestos. In 05', I was diagnosed with that left lung nodule. May this have caused my nodule?

You're still alive: If the nodule was found ten years ago, and you had no illness as a result, then this is not cancer. If it were cancer, you might have a pretty good case. I'm glad it's not. Asbestosis itself presents as diffuse thickening of the lung texture, or of the pleural surfaces. Most lung nodules in non-smokers (hope that's you) are old histoplasmosis, which is harmless. Thanks for your service. ...Read more

Many types of tumor: If a lung lesion was noted as solitary and no previous history of underlying disease with bx of mesothelioma then Asbestos has been associated with such lung lesions. Squamous Ca usually derived from smoking and adenoCa from a viral source. At this time worth while to get PET/CAT to assure all path absent from lung or metastatic foci. ...Read more

I had colon cancer three years ago, now nodule on left lung. Could it be cancer again?

Yes: Depending on the Dukes classification as to extent of tumor into bowel wall and number of lymph nodes involved the chances of a lung lesion being metastasis is a possibility. A PET/CAT will help identify the lesion as met or not. If neg. careful follow up and possible biopsy might be necessary. ...Read more

I had a CT scan which showed a 3-4 mm nodule in the lower left lung. I was a smoker for 40 years. Does that have anything to do with it?

I had a CT scan which showed a 3-4 mm nodule in the lower left lung. I was a smoker for 40 years. Does that have anything to do with it?

Can't Tell Yet: Is the nodule uncalcified? Is this the first time it has been identified? Any prior ct scans? If this is a new finding with no prior scans there will probably be a suggestion to rescan you in 6 months to check for growth. If no change then another scan 12 months after the repeat. Most such nodules are incidental and are sequelae of prior infections. Important to followup though. ...Read more

Ct scan with contrast found a 3mm nodule in my left lung, minimal dependent atelectasis, & an exaggerated cardiac silhouette. What does this mean?

Pulmonary nodule: Any nodule in the lung, no matter what size, needs to be investigated thoroughly. Comparison with previous chest xrays and CT scans would be the priority. If you smoked tobacco, then further tests such as a PET scan and a biopsy and bronchoscopy are indicated. Please see a pulmonologist soon. Best wishes. ...Read more

What's it mean if CT scan says I have a 4 mm nodular density in lower left lung postero-laterally? In 2012 it was at 3mm now in 2015 it was 4mm

What's it mean if CT scan says I have a 4 mm nodular density in lower left lung postero-laterally? In 2012 it was at 3mm now in 2015 it was 4mm

Depending on how: the scans were performed, they may or may not be reliably comparable when measuring tiny nodules. Additionally, studies show significant intra-observer variability when measuring small nodules. So the first order of business is having one person look at both scans and determine if the size has really changed. If yes, further workup might be needed. If no, then probably nothing needs to be ddone ...Read more
