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

Let's not jump into: The worst conclusions. Your are 30 y/o, nonsmoker. If you look at the study, 1994, univ of miami, people who developed lung cancer under age 36 were mainly exposed to marijuana, inconclusive but something to think about. In all likelihood this is part of your rheum problem such as rheumatoid nodules or infectious such as fungal. You need a bronch/biopsy for dx. I wish you luck, keep spirits up. ...Read more

Are small lung nodules cancer?

Are small lung nodules cancer?

Needs biospy: Small nodules can be cancer, but they would need to be biopsied. Many times, the nodules are just scars and not cancer. If you find nodules on a cat scan of your chest, depending on the size, they need to be followed to make sure they don't grow or look ominous enough to warrant a biopsy. What to do about nodules also depends on your risk for lung cancer, i.e., were/are you a smoker, etc. ...Read more

Calcified lung nodules?

Generally no worries: These are likely "healed" TB or fungal infection that the body has "walled off" and calcified. Usually called calcified granulomas. Very common, especially in certain parts of the world where specific fungi are endemic in the environment - in those areas, nearly every one has them and they do no harm. ...Read more

Severe chest pain, calcium screening showed chronic pulmonary hypertension& lung nodules. Had CT of chest 3mm & 8mm noncalcified granulomas.helpplease?

Lung nodules: many causes of lung granulomas. Histoplasmosis a fungus in the dirt is probably most common cause. Being around construction sites or bird handling are frequent causes especially around Ohio river. Connective tissue causes like sarcoidosis and wegeners can also cause. Working in dusty areas or around talc is known cause. With pulmonary hypertension you need to see a pulmonologist for definitive dx ...Read more

Lung CT scan impression: multiple small nodules largest 6mm ill-defined semisolid noncalcified medial left upper lobe ?

Lung Nodules:: It is fairly common for people to have benign lung nodules that are incidentally found on ct scans. Would recommend a follow-up scan in a few months just to make sure they are not growing. If you smoke, please stop! but, i wouldn't be too worried about these small lung nodules. Check back with your physician for a follow-up plan. ...Read more

Thyroid u/s: 3x2x3mm cystic nodule, ill-defined 1.6x0.8x1.0cm hypoechoic nodule r lobe; 6x3x6mm solid, slightly hypoechoic nodule l lobe- next step?

Followup exam: By age 60, about one-half of all people have a thyroid nodule, found either through examination or with imaging. Over 90% of such nodules are benign. Hypoechoic noodules are usually cysts. A complex nodule over one cm. With blood flow should be biopsied. This can be performed by neeedle or core bx. Most nodules are asymptomatic. Follow up us examination in six months suggested. ...Read more

Ct chest adrenal nodule 1.9 CM right. Lungs demonstrate babisalar dependent atelectasis small subpleural bullae noted right up lobe trace pericardial?

Adrenal eval: Hi. The adrenal nodule needs to be evaluated. What were the Hounsfield units on the non-contrast scan of the nodule? Your endocrinologist will determine: 1) if it's producing any hormones, and 2) if it's growing. If high Hounsfield units, it needs sooner evaluation. Any hirsutism, amenorrhea, diabetes, serious high blood pressure, sweating, headache, palpitations, etc? Good luck! ...Read more

What's a 14mm noncalcified left upper lobe parenchymal pulmonary mass adjacent atelectasis.Left upper lobe bronchus/hillar peribronchial cuffing/thick?

Mgt PHI: The imaging may be uploaded to an inbox consultation. From your description I would suggest a follow up imaging study with an evaluation with additional information. Have you smoked? Is there a family history of cancer? Have you been tested for any infections? The mass is probably impinging on the airway and causing areas of collapse, called atelectasis. This area is prone to secondary infection ...Read more

Ct angiogram shows non calcified opacity on middle lobe 4mm. Appearance of benign intrapulmonary lymph node on lung with no pleural abnormalites.

Ct angiogram shows non calcified opacity on middle lobe 4mm. Appearance of benign intrapulmonary lymph node on lung with no pleural abnormalites.

Opacity: The question to your doctor should be - is this an incidental pulmonary nodule or something more concerning. If the ct angio was done for something completely unrelated, and it was a true incidental finding, some guidelines say that under a certain size (4mm) for low risk patients (no smoking, etc), then no follow up is needed. Otherwise a biopsy or interval imaging followup is appropriate. ...Read more

Chest CT scan subsegmental atelectasis versus fibrosis in medial margins of r \l upper lobes abutting mediastinum was f/u for 6mm ground glass nodule

The fibrosis and : Atelectasis isnt anything to worry about, just some lung tissue collapsed on itself and scarring. The ground glass nodule is something that may need longer term follow up to make sure it doesnt grow. These can be due to something called atypical adenomatous hyperplasia (aah). ...Read more

+ PPD test, CT scan solitary pulmonary nodule. 5mos after nodule stable/slight increase pet2.9suv bronchoscopy inflammatory no cough doc said remov?

Curious: More information is required. The pet uptake (measured in standard uptake value or suv), is low level, but not low enough to guarantee benignity. Given age and + ppd, i would suspect this could be an active granuloma. Given your age, i would encourage consultation with a pulmonologist and full review of all your records first. Lung surgery is serious business. ...Read more

Lung nodules 7 mm are they a concern?

Lung nodules 7 mm are they a concern?

It depends: Not all lung nodules are alike. The odds that a nodule is cancer depends in the appearance and size of the nodule, the medical history of the patient, the smoking history of the patient, and how the nodule changes over time. Radiologists, pulmonary physicians and thoracic surgeons are best qualified to determine the risk that a particular nodule is cancer. ...Read more
