Doctor insights on: Non Calcified Lung Parenchymal Nodule In Right Lower Lobe

Share

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

What is a pasterior right lower lobe pareachynal nodule abutting. The pleaura exhibits stripped internal calcification just need to know what it is

What is a pasterior right lower lobe pareachynal nodule abutting. The pleaura exhibits stripped internal calcification just need to know what it is

A : A parenchymal nodule is an area of abnormal density in the tissue of the lung. The fact that it abuts the pleura means that it is at the edge of the lung. Based on that description alone, this could be just about anything, from an area of infection to a tumor. The fact that is contains calcium in it means that it has been present for a while, and that usually means a benign process, but that can't really be determined without comparing to old studies or doing follow-up images to show no change over time. ...Read more

I have a 4mm nodule in my right lower lung lobe. Doctors suspect its benign. Risk outweighs benefits to aspirate it out.Do nodules hurt? I feel pain

I have a 4mm nodule in my right lower lung lobe. Doctors suspect its benign. Risk outweighs benefits to aspirate it out.Do nodules hurt? I feel pain

No: The short answer is no, lung nodules are in areas of the body which do not have pain receptors. A nodule that involves the pleura (lining or edge) of the lung might present with pain if large enough and if it grows through the parietal pleura (lining of the chest wall) but a 4mm lung nodule would not be painful. ...Read more

(36 and smoker)What could 3 noncalcified lung nodules sizes 6mm- 4mm left lower lobe be? Found on ct, what would be next step to identify cause?

Many possibilities.: Noncalcified lung nodules are worrisome, especially if you are a smoker (as you have), & more so if you are a "heavy" smoker (based on number of packs per day, & no of yrs that you've smoked). A nodule could be scar tissue, or the effects of an infection or radiation; however, most worrisome, of course, is lung cancer. To identify cause, next step is usually bronchoscopy (scope to look) & biopsy. ...Read more

Questionable right lower lobe lung nodule vs end on vessel a followup x-ray is recomended in 3 month to reassess.No acute anatomic finding. any wrong?

Questionable right lower lobe lung nodule vs end on vessel a followup x-ray is recomended in 3 month to reassess.No acute anatomic finding. any wrong?

Unclear: The lauded radiologist, whoever it was that issued the report, is uncertain as to whether a nodule was found in the lung, or if there was a confounding shadow from a vessel. That is why he/she recommends a repeat of the exam (X-ray) in 3 months. A malignant nodule would get bigger. A stable appearance suggests a benign anomaly or artifact. Without seeing the actual film, nothing more can be said. ...Read more

Pleural bassed nodule at posterior aspect os mid cephalad right lower lobe of lung 7 x 4 mm. Also linear atelectasis within right midlung. Age 73?

Pleural bassed nodule at posterior aspect os mid cephalad right lower lobe of lung 7 x 4 mm. Also linear atelectasis within right midlung. Age 73?

Future evaluation: Nodules can be very common in the chest. A lot of the decision of what to do with your nodule depends on your smoking history. If you have never smoked then the likelihood that this represents an early cancer is low. There is a national guideline in the United States for repeating a series of ct scans to ensure that the nodule does not grow. Your doctor will plan this out with you. ...Read more

I had a CT done on my abdominal area and it found a 3mm non calcified subpleural nodule seen posterolaterally in the left lower lobe. Thoughts?

I had a CT done on my abdominal area and it found a 3mm non calcified subpleural nodule seen posterolaterally in the left lower lobe. Thoughts?

Frequent finding: Ct's frequently show "incidental" findings. In most cases, they do not represent any serious disease. Often your radiologist and physician will recommend some follow-up, such as repeating the ct in about 3 months to make sure the nodule isn't growing (ie a possible cancer, rather than old scar). If you are at high risk for lung cancer (a smoker), more tests might be ordered immediately. ...Read more
