Should i be concerned about CT checking my thymus due to mg and or lems showing a right lower lobe solitary pulmonary subpleural nodule 6mm?

Should i be concerned about  CT checking my thymus due to mg and or lems showing a right lower lobe solitary pulmonary subpleural nodule 6mm?

No worries: A nodule of that size in a person of your age is overwhelming benign. Lung cancer is very uncommon in young adults. There are many causes to have lung nodules that are not cancer. ...Read more

Nodule (Definition)

Any growth or deposit in the body or on its surface may be casually termed a nodule until its character is determined by the familiarity of the physician with it or by the results of a biopsy if it is not so obvious. The term is casual ...Read more

How is a 5mm non-calcified lower lobe pulmonary nodule in a non-smoker managed? Was found incidentally on a contrast CT of abdomen.

Recommendation: Fleischner society recommendation for nodule this size is follow up ct at 12 months and, if no change, no further follow up for low risk(e.g. Nonsmoker etc..) patient. For high risk patient, follow up CT at 6-12 months and then at 18-24 months if no change. ...Read more

CT SURVEILLANCE: Accp guidelines recommend 2 years of low dose ct surveillance. Repeat ct 3 months x 2 then 6 months x 3 for a total of 2 years. Probably nothing. ...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

Is a 6mm pulmonary nodule in the right upper lobe too small to biopsy?

Is a 6mm pulmonary nodule in the right upper lobe too small to biopsy?

Probably so: Biopsy of a lung nodule depends on the size and location. A nodule smaller than 1 cm is difficult to biopsy. A nodule located too close to the heart or main blood vessels is difficult to biopsy. A nodule too adjacent to the ribs may also be difficult to biopsy. In your case ct follow up at intervals by established guidelines may be considered. ...Read more

Ct shows 2 mm & smaller indeterminant pulmonary nodules, in the right lower lobe. Tiny subpleural lymph nodes along the fissures. What causes this?

A lot of things: If just 2 mm, i would just monitor with a ct scan every 6 months for a year and then every year thereafter. Possibilties include exposure to fungus, old infection, dust or malignancy but this is less likely. Hope this helps. ...Read more

2mm lung nodule lower left lobe - unrelated CT found it - on 1yr fu it's now 4mm. Any reason other than cancer it would grow? I just quit smoking.

2mm lung nodule lower left lobe - unrelated CT found it - on 1yr fu it's now 4mm. Any reason other than cancer it would grow? I just quit smoking.

Benign possibilities: There are many benign causes of a solitary pulmonary nodule. However, with a smoking history, you probably ought to have it biopsied, if possible, or even removed. This is to be certain that this isn't due to an early malignancy whose removal would likely be curative. Kudos to you for smoking cessation; keep up the good work. Good luck! see a cardiothoracic surgeon for evaluation. ...Read more

When my 6mm lung nodule was found on CT, slight "alvelitis" was found on the right upper lobe. What is alvelitis?

Alveolitis: This is inflammation of the Alveoli,...the pulmonary (lung) alveoli are the terminal ends of the respiratory tree, which outcrop from either alveolar sacs or alveolar ducts, and which are both sites of gas exchange with the blood as well. ...Read more

I have just been diagnosed with a Lung Nodule. It is in Right lung btween upper two lobes. My father died from Squamous Cell. Should it be watched 6 m?

I have just been diagnosed with a Lung Nodule. It is in Right lung btween upper two lobes. My father died from Squamous Cell. Should it be watched 6 m?

Lung nodules: are very common and fortunately most of the time are benign. Some need to be watched and other do not. Certain characteristics such as the size, morphology and your smoking history dictate the necessity and timing of follow up imaging studies. More information is needed to properly answer your question :) ...Read more

What is a noncalcified pulmonary nodule? Is it treatable?

It is a small: lung mass. There are benign and potentially malignant causes. Whether it needs workup depends on its imaging features and your clinical history. Sometimes a biopsy is necessary to determine what it is, other times it can be safely followed or ignored. The presence of calcification is important because most of the time a calcified nodule is benign. ...Read more

Is a solitary pulmonary nodule if calcified , a glanuloma?

Not necessarily: Central calcification, laminated or stippled calcification (popcorn) calcified nodules are benign. However, calcifications on the edge or periphery of a nodule could still be malignant and need further evaluation with followup ct scan, pet scan and/or biopsy. ...Read more

What is the definition or description of: pet-ct pulmonary nodule?

What is the definition or description of: pet-ct pulmonary nodule?

Lung mass: If a lung mass is seen on chest xray or ct scan and the patient has a moderate risk of malignancy, often the next test is a positron emission tomography (pet scan). This test detects masses with high metabolic rates. Around 95% of patients with a malignant nodule will have a positive pet scan. It is falsely positive in about 21% of patients, meaning that it will suggest cancer when it is not. ...Read more

I have a pulmonary nodule that was 5 mm in 07/2013. As of 09/2014 it is 6 mm. Would you recommend a follow up next year? I haven't smoked in 30 years

Work-up now: The nature of the nodule needs to be established now rather than waiting for a year. You may wish to discuss with your doctor other diagnostic modalities, e.g., Pet scan and consultation with a pulmonary specialist. ...Read more
